Quick Answer

Float tanks contain a saturated solution of magnesium sulfate with a specific gravity of 1.23 to 1.3, maintained at approximately 92–96°F (33.3–35.6°C) for flotation [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf].
Health departments often regulate float tanks like pools or spas, which can sometimes lead to regulations such as "continuous filtration" that may not be suitable for float tank systems [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/].
The Floatation Tank Association (FTA) officially updated its North American Float Tank Standards in 2025, offering best practices to ensure quality, sanitation, and safety in commercial float operations [https://www.floatation.org/standards-regulations].
Since float tanks rarely use traditional chemicals like chlorine for water treatment, effective disinfection methods such as ozone or ultraviolet (UV) are crucial to reduce the likelihood of pathogen transmission [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf].

Ensuring proper sanitation in float tanks is critical for client safety and the overall integrity of the float therapy experience. Float tanks, also known as float rooms or sensory deprivation tanks, operate with unique water chemistry. They typically hold a concentrated magnesium sulfate solution, which has a specific gravity ranging from 1.23 to 1.3, making the water exceptionally dense and buoyant [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. This solution is kept at a skin-neutral temperature of approximately 92–96°F (33.3–35.6°C) to minimize sensory input [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. Because of this unique environment, standard pool and spa regulations often do not directly apply or are impractical. Many health departments classify float centers in various ways, sometimes as pools or spas, or even as tattoo parlors or hair salons, leading to a complex regulatory landscape [https://www.floatation.org/standards-regulations]. The Floatation Tank Association (FTA) and organizations like NSF International work to develop specific guidelines, with the FTA updating its North American Float Tank Standards in 2025 to provide clear best practices for sanitation and safety [https://www.floatation.org/standards-regulations]. These guidelines emphasize the need for effective disinfection methods like ozone or UV, as traditional chlorine is rarely used in float tank systems [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf].

What are Float Tanks and Why is Sanitation Different?

Float tanks are specialized tubs designed for relaxation therapy, where individuals float in a highly saturated solution of magnesium sulfate. This unique environment is engineered to reduce external stimulation like sound, touch, and light [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. The water in these tanks is not just ordinary water; it is a dense saline solution that requires a distinct approach to sanitation compared to typical swimming pools or spas.

The Unique Chemistry of Float Tank Water

The core of a float tank is its water solution. This solution contains magnesium sulfate, commonly known as Epsom salt, in a very high concentration. We know that float tanks hold a saturated solution of magnesium sulfate with a specific gravity of 1.23 to 1.3 [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. This high specific gravity is what allows a person to float effortlessly on the surface, creating the unique sensation of weightlessness. The water temperature is also carefully controlled, typically maintained at approximately 92–96°F / 33.3–35.6°C [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. This temperature is close to skin temperature, further enhancing the sensory deprivation experience by making it difficult to discern where the body ends and the water begins. These precise parameters are crucial for the therapeutic benefits of floating.

Risks of Improper Sanitation

Despite the high salt content, float tank water is not immune to pathogens. When the water solution used in floatation tanks is not properly treated, pathogens can survive, allowing for increased risk of disease transmission [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. This risk underscores why diligent sanitation practices are not just a recommendation but a necessity. The warm, enclosed environment, if not properly managed, could become a breeding ground for various microorganisms. This is a primary concern for both float center operators and health departments, highlighting the need for robust and effective disinfection systems.

Distinct Disinfection Methods

A key difference in float tank sanitation, compared to pools, lies in the disinfection methods used. Floatation tanks rarely use chemicals like chlorine to treat the water [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. Chlorine, while effective in pools, can react poorly with the high concentration of Epsom salts and may cause skin irritation in such an environment. Instead, float tank systems need to incorporate other effective disinfection methods. Ozone or ultraviolet (UV) are prime examples of alternative disinfection methods that are incorporated to reduce the likelihood of pathogen transmission [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. These methods effectively neutralize bacteria and viruses without introducing harsh chemicals into the solution, preserving the integrity of the float experience and ensuring user safety. The need for these alternative systems is why float tanks are distinct from swimming pools and other recreational water, leading to questions about the efficacy of various disinfection methods [https://ncceh.ca/sites/default/files/Float_Tanks_Considerations_EPH_July_2016.pdf].

Float Tank Terminology

Floatation tanks go by many names. They can be referred to as float tanks, float rooms, pods, spas, chambers, isolation tanks, or sensory deprivation tanks [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. Regardless of the name, the fundamental principles of their operation and the critical need for proper sanitation remain the same. Understanding these unique aspects of float tanks is the first step in appreciating why their sanitation standards are a specialized field, demanding attention beyond general pool and spa regulations. We at Float Finder believe that recognizing these distinctions is essential for both operators and consumers to ensure a safe and beneficial float experience.

Who Sets the Rules for Float Tank Sanitation?

The regulatory landscape for float tank sanitation is complex and often varies significantly by location. Unlike some other industries, there is no single, overarching national pool code in the United States or Canada that dictates how float tanks should be regulated [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. This fragmented system means that operators and consumers must look to various levels of government and industry bodies for guidance.

State, Provincial, and Local Control

The primary authority for pool rules and regulations typically rests at the state or provincial level [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. This means that each state or province has its own unique set of regulations governing recreational water facilities. While there might be similarities between these different codes, there can also be significant differences, even in fundamental aspects like ideal pH levels. Adding another layer of complexity, counties and cities often enforce their own additional pool rules on top of what the state or provincial rules dictate [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. This multi-layered approach results in a fractured system where the specifics of getting float tanks approved can differ hugely from one place to another. A float center might be classified as a pool or spa, a tattoo parlor, or even a hair salon, depending on the local health department [https://www.floatation.org/standards-regulations]. This lack of a unified classification often leads to confusion and inconsistency in enforcement.

The Role of the CDC and Model Aquatic Health Code

Despite the absence of a national code, federal agencies do provide guidance. The Centers for Disease Control and Prevention (CDC) plays a significant role in developing recommendations for the operation and maintenance of aquatic facilities. The CDC’s 2023 Model Aquatic Health Code (MAHC) includes recommendations for floatation tanks [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. The MAHC is not a federal law but rather a suggested code that health departments can use when regulating pools, spas, and other recreational waters, including floatation tanks [https://www.floatation.org/standards-regulations]. This guide combines information from the CDC's MAHC and its website to highlight key recommendations for safely managing floatation tanks. For more detailed information, operators and health departments are directed to cdc.gov/mahc. This provides a valuable, evidence-based resource that local jurisdictions can adapt to their specific needs, aiming to standardize best practices even within a fragmented regulatory system.

Industry Associations and Standards

Recognizing the need for specific guidance, industry organizations have stepped in to develop best practices for operating float tanks. The Floatation Tank Association (FTA) is one such organization. Its Sanitation and Regulations Committee has officially updated the North American Float Tank Standards, providing best practices to ensure quality, sanitation, and safety while operating float tanks [https://www.floatation.org/standards-regulations]. This 2025 version of the standards offers a comprehensive set of recommendations for the float community. Another key organization is NSF International, which creates product safety standards and certifications. Standard language for float tanks is included in their NSF/ANSI/CAN 50 Standard for recreational water facilities [https://www.floatation.org/standards-regulations]. These industry-led standards are crucial because they are specifically tailored to the unique characteristics of float tanks, addressing aspects that general pool codes often overlook. They represent the collective knowledge and experience of float experts, working to ensure the highest levels of safety and cleanliness. The Floatation Tank Association, based in Richmond, Virginia, is a key player in this effort, working to advance the health, wellness, and fitness aspects of floating [https://www.linkedin.com/company/floatation-tank-association].

The Challenge of Interpretation

Ultimately, because almost none of the existing pool rules have anything specific to say about float tanks, how they should be regulated often becomes a matter of the personal opinion of your local health department official [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. This variability means that float center operators must be proactive in working with their local health departments, educating them on the unique nature of float tanks, and advocating for sensible regulations that ensure safety without imposing impractical requirements. The efforts of organizations like the FTA and the guidance from the CDC’s MAHC provide valuable tools for these discussions, helping to bridge the gap between general aquatic regulations and the specific needs of float therapy.

How Do Health Departments Regulate Float Tanks?

When a new float center seeks approval, one of the most significant challenges involves navigating local health department regulations. Due to the lack of specific, widespread codes for float tanks, health departments often take one of several approaches, which can lead to varied and sometimes illogical requirements. For more details, see Floatation Tank Association Standards and Regulations.

Regulating Like a Pool (with Exceptions)

A common approach health departments take is to classify float tanks as pools or spas, and then apply existing pool/spa codes to them [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. While this provides a framework, it often means that float centers are asked to follow rules that are not designed for their unique environment. For example, some pool codes might lead to pretty ridiculous rules, such as having a "No Diving" sign posted in front of each float tank or requiring a lifeguard on duty [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. These regulations, while sensible for a swimming pool, make no practical sense for a small, shallow float tank.

Even less obviously absurd rules can conflict with running a float tank effectively. One of the most common pool regulations, for instance, is "continuous filtration," which requires the pump system to run all the time [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. For a float tank, where the goal is often reduced sensory input and the water is highly saline, continuous filtration might not be the most efficient or even necessary approach when other disinfection methods are in place. The argument here is that equating pools and spas with floatation tanks may create unintended negative consequences to the health of the floater and place unfair and unnecessary burden on the float tank operator [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. This highlights the need for a nuanced understanding of float tank operations by regulatory bodies.

The Influence of Local Officials

The specifics of float tank regulation can often come down to the personal opinion of your local health department official [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. Because most existing pool rules do not specifically address float tanks, the interpretation and application of these rules can vary widely from one inspector to another. This makes the approval process unpredictable for float center operators. It also underscores the importance of proactive communication and education between float center owners and their local health departments. Operators often find themselves needing to explain the unique nature of float tanks, their specific sanitation protocols, and why certain traditional pool regulations are not applicable or beneficial. This is where resources like the North American Float Tank Standards become invaluable.

Evolving Standards and Best Practices

To address these challenges, the float industry is actively working to provide clear, evidence-based guidelines. The Floatation Tank Association (FTA) is at the forefront of this effort. Its Sanitation and Regulations Committee officially updated the North American Float Tank Standards in 2025 [https://www.floatation.org/standards-regulations]. These standards represent recommendations for the baseline best practices to ensure quality, sanitation, and safety while operating float tanks in a commercial setting [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. The standards are supported by an appendix that explains the research and reasoning behind the recommendations, along with supporting documentation. This level of detail helps to provide a solid foundation for discussions with health departments, offering a comprehensive framework that is specifically designed for float tanks.

Furthermore, the CDC’s Model Aquatic Health Code (MAHC) also aims to continue developing a suggested code for health departments to use when regulating pools, and this includes regulations for floatation tanks [https://www.floatation.org/standards-regulations]. The MAHC provides a quick guide for health departments and operators on safely managing floatation tanks, highlighting key recommendations from the 2023 MAHC [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. These resources are vital tools for operators to present a coherent and well-supported case for float-specific regulations, ensuring that safety is paramount without imposing unnecessary burdens.

The Need for Float-Specific Regulations

In jurisdictions that do not already have standards for float tanks, there is often an attempt to initially place them in the same category as pools or spas [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. Doing so ignores the unique nature of floating, leaving out inherent characteristics important to float tank safety and enforcing others that make no sense for the small, saline environment. This is why the development and adoption of float-specific standards are so crucial. They help to educate regulators and provide a clear path for ensuring public health and safety in a way that is appropriate for the float industry.

What are the Industry Best Practices for Float Tank Sanitation?

Industry best practices for float tank sanitation are designed to ensure public safety and the quality of the float experience, taking into account the unique nature of the highly saline environment. These practices go beyond general pool rules and are specifically tailored to the challenges and characteristics of float tanks. Organizations like the Floatation Tank Association (FTA) and NSF International are key players in developing and disseminating these standards.

The North American Float Tank Standards

The Floatation Tank Association (FTA) is a leading organization in the US dedicated to developing best practices for operating float tanks [https://www.floatation.org/standards-regulations]. The FTA's Sanitation and Regulations Committee has produced the North American Float Tank Standards, which were officially updated in 2025 [https://www.floatation.org/standards-regulations]. These standards represent our recommendations for the baseline best practices to ensure quality, sanitation, and safety while operating float tanks in a commercial setting [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. The recommendations are not arbitrary; they are based on the current evidence that exists for float tanks, in addition to decades of operational experience, dating back to the invention of the commercial float tank in the 1970s [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. This historical context is important, as it shows a long-standing commitment to safety and innovation within the industry.

These comprehensive standards include detailed guidance on various aspects of float tank operation, from water quality parameters to facility design and maintenance. The standards are supported by an appendix that explains the research and reasoning behind these recommendations, as well as some supporting documentation. This transparency allows operators and health departments to understand the scientific and practical basis for each guideline. The goal is to provide a robust framework that ensures a consistently safe and hygienic environment for all floaters.

NSF International Standards

Another important contributor to float tank sanitation standards is NSF International. This organization is known for creating product safety standards and certifications across various industries. For recreational water facilities, their NSF/ANSI/CAN 50 Standard includes specific language for float tanks [https://www.floatation.org/standards-regulations]. This standard provides criteria for the design, construction, and performance of equipment used in recreational water facilities, including filtration systems, pumps, and disinfection equipment. Compliance with NSF standards signals that equipment has been rigorously tested and meets recognized health and safety benchmarks. For float center operators, selecting NSF-certified equipment can be a crucial step in demonstrating a commitment to high sanitation standards and can often simplify the approval process with local health departments.

CDC Recommendations for Operation and Maintenance

The Centers for Disease Control and Prevention (CDC) also provides valuable recommendations through its Model Aquatic Health Code (MAHC). The MAHC includes a quick guide specifically for floatation tanks, offering guidance for both local, state, tribal, and territorial health departments and floatation tank/spa operators [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. This guide highlights key information from the CDC's 2023 MAHC and website. The MAHC emphasizes critical aspects such as the water supply. It states that water used by floatation tank facilities should be from a potable source [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. Potable water is clean, safe drinking water, which is a fundamental requirement for any facility where people immerse themselves. This ensures that the water entering the system is free from initial contaminants. For more details, see CDC Model Aquatic Health Code Quick Guide.

Essential Disinfection Methods

As discussed, float tanks rarely use chlorine. Therefore, effective alternative disinfection methods are paramount. The CDC quick guide explicitly states that since floatation tank systems rarely use chemicals like chlorine to treat the water, other effective disinfection methods, like ozone or ultraviolet (UV), need to be incorporated to reduce the likelihood of pathogen transmission [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. We know that ozone and UV systems are highly effective at neutralizing bacteria, viruses, and other microorganisms without altering the chemistry of the Epsom salt solution or causing skin irritation. These systems are typically integrated into the filtration loop, ensuring that all water passes through the disinfection stage regularly. The basics of float tank sanitation, including the various methods of sanitizing float solution, are essential for operators to understand and implement [https://www.floattanksolutions.com/basics-float-tank-sanitation/].

Continuous Improvement and Collaboration

The float industry is dynamic, with ongoing research and development in sanitation technologies and best practices. The FTA encourages members to submit change requests for additions or modifications to the North American Float Tank Standards, demonstrating a commitment to continuous improvement and responsiveness to new evidence and operational experience. This collaborative approach, involving operators, health departments, and industry experts, ensures that sanitation standards remain robust, practical, and effective in safeguarding public health while supporting the growth and integrity of float therapy.

Why are Specific Float Tank Standards Important?

The development and implementation of specific float tank standards are crucial because float tanks possess unique characteristics that differentiate them significantly from traditional pools and spas. Attempting to regulate float tanks solely under existing pool or spa codes can lead to inappropriate requirements, potential health risks, and unnecessary burdens on operators.

Recognizing Unique Characteristics

A primary reason for specific standards is that equating float tanks with pools or spas ignores the unique nature of floating [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. Float tanks are not simply smaller pools. Their high concentration of magnesium sulfate creates a dense, sterile-like environment that inherently inhibits the growth of many microorganisms. The water temperature, typically maintained at 92–96°F (33.3–35.6°C), is also distinct from typical pool temperatures. Furthermore, the very purpose of a float tank – sensory reduction – means that certain features common in pools, such as continuous loud filtration or chemical smells, would directly contradict the therapeutic goal.

The absence of specific float tank regulations often leads health departments to default to pool or spa codes. In jurisdictions that do not already have standards for float tanks, there is often an attempt to initially place them in the same category as pools or spas [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. This approach can result in overlooking inherent characteristics important to float tank safety, such as the self-sanitizing properties of a highly saline solution, or the need for specific non-chlorine disinfection methods.

Preventing Unintended Negative Consequences

Applying general pool/spa rules to float tanks can create unintended negative consequences for floater health [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. For instance, if a float tank were forced to use chlorine as its primary disinfectant, the chemical could react unpredictably with the high concentration of Epsom salt, potentially forming irritating compounds or reducing the efficacy of the disinfection. This could lead to skin irritation, respiratory issues, or other adverse reactions for floaters, directly undermining the wellness benefits of float therapy. The unique chemistry of the float solution demands specific considerations for disinfectants to ensure both effectiveness against pathogens and user comfort.

Moreover, the high salt content itself requires specialized filtration and heating equipment. Standard pool equipment may not withstand the corrosive nature of the concentrated saline solution, leading to equipment failure or inefficient operation. This is why the NSF/ANSI/CAN 50 Standard for recreational water facilities includes specific language for float tanks, acknowledging these distinct equipment needs [https://www.floatation.org/standards-regulations].

Reducing Unfair Burdens on Operators

Without specific standards, float tank operators often face unfair and unnecessary burdens [https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf]. They may be required to implement costly changes to their pump systems or install features like "No Diving" signs that are irrelevant to a float tank environment [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. These mandates can significantly increase operational costs without providing any tangible improvement in safety or sanitation for the specific float environment. For a small business, such arbitrary requirements can be a major barrier to entry or continued operation.

Specific float tank standards provide clarity and predictability for operators. They outline clear expectations for sanitation, equipment, and operational procedures that are relevant and effective for float tanks. This allows operators to invest in appropriate technologies and practices, ensuring compliance without wasteful spending on irrelevant or counterproductive measures. The North American Float Tank Standards, updated in 2025 by the FTA, are designed to provide these clear guidelines, offering baseline best practices for quality, sanitation, and safety [https://www.floatation.org/standards-regulations].

Ensuring Effective Pathogen Control

Perhaps most importantly, specific standards ensure that the unique saline environment of float tanks is properly managed for safety. While high salt content is antimicrobial, it does not eliminate all pathogens. Effective disinfection methods like ozone or UV are necessary to reduce pathogen transmission in float tanks [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. These systems are integral to float tank sanitation and require specific operational parameters and maintenance schedules, which are best addressed through tailored standards. The CDC's Model Aquatic Health Code also includes recommendations for floatation tanks, providing a framework for health departments to consider when developing local regulations [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. By developing and adopting specific float tank standards, the industry and regulatory bodies can work together to ensure the highest level of safety and hygiene, fostering trust and confidence in float therapy.

Where Can I Find Local Float Tank Regulations?

Navigating the regulatory landscape for float tanks can be challenging due to the fragmented nature of health codes across different jurisdictions. Since there is no single national pool code in the United States or Canada, finding the specific rules that apply to a float center requires targeted research at the local level. For more details, see Float Tank Solutions on Health Department Approvals.

Starting with Your Local Health Department

The most effective way to find the regulations that apply to your center is to visit your city, county, or state's health department website [https://www.floatation.org/standards-regulations]. This is the primary point of contact for all public health matters, including those related to recreational water facilities. Health department websites often contain downloadable codes, regulations, and guidelines for businesses that operate pools, spas, or similar facilities. It is crucial to look specifically for any sections that might address floatation tanks, sensory deprivation tanks, or even general "special use" aquatic facilities. If explicit regulations for float tanks are not immediately apparent, it is advisable to contact the health department directly. Speaking with an environmental health specialist or inspector can provide clarity on how they classify and regulate float tanks in your specific area. They can explain which existing codes they apply and whether they make any exceptions for the unique characteristics of float tanks.

Resources from the Floatation Tank Association

The Floatation Tank Association (FTA) recognizes the difficulty operators face in finding local regulations and has made efforts to compile relevant information. The FTA provides a list of standards for many US cities and counties on its "Standards & Regulations" page [https://www.floatation.org/standards-regulations]. While this resource is a helpful starting point, it is important to remember that regulations can change, and operators should always verify the most current information directly with their local health department. The FTA also actively encourages the float community to help keep this information up-to-date by sending in any updated codes they find. This collaborative approach underscores the industry's commitment to transparency and compliance.

For example, the FTA's resource indicates that for states like California, multiple local and county regulations exist, meaning you would need to call your local department of health for specific information [https://www.floatation.org/standards-regulations]. Similarly, in states such as Rhode Island, Arkansas, and Louisiana, there are no known statewide regulations, which means operators should look for county-specific regulations [https://www.floatation.org/standards-regulations]. Other states like Connecticut, Illinois, Missouri, New Mexico, and Wisconsin are listed as having specific standards available. This highlights the varied landscape and the necessity of local inquiry.

Understanding Classification Challenges

One of the main reasons for the difficulty in finding specific float tank regulations is that not all health departments have specific codes or regulations for float centers [https://www.floatation.org/standards-regulations]. As a result, a float center may be classified in various ways, such as a pool or spa, a tattoo parlor, or even a hair salon [https://www.floatation.org/standards-regulations]. This varied classification can significantly impact which set of regulations applies to your facility. For instance, if a float tank is classified as a pool, it might be subject to regulations like "continuous filtration," which may not be ideal for a float tank [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. This is why understanding the local health department's classification is so important.

Leveraging Industry Standards and Model Codes

When local regulations are unclear or absent, operators can proactively refer to industry best practices and model codes. The North American Float Tank Standards, updated by the FTA in 2025, provide comprehensive recommendations for quality, sanitation, and safety in commercial float settings [https://www.floatation.org/standards-regulations]. These standards are based on decades of operational experience and current evidence, offering a robust framework that can be presented to health officials. Additionally, the CDC’s 2023 Model Aquatic Health Code (MAHC) includes recommendations for floatation tanks, which can serve as a valuable reference for health departments looking to develop or update their own codes [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. By presenting these well-researched and industry-backed standards, float center operators can advocate for sensible and appropriate regulations that ensure public health and safety without imposing unnecessary or impractical requirements. This collaborative approach often leads to more favorable outcomes for both the float center and the community it serves.

Frequently Asked Questions

What is the typical specific gravity of float tank water?

Float tank water is highly concentrated with magnesium sulfate, giving it a specific gravity ranging from 1.23 to 1.3 [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. This high density allows individuals to float effortlessly on the surface. Maintaining this specific gravity is crucial for the unique buoyancy and therapeutic experience of float therapy.

Do float tanks use chlorine for sanitation?

No, float tanks rarely use chlorine for water treatment [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. The high concentration of Epsom salts can react unpredictably with chlorine, and it may cause skin irritation in the enclosed, warm environment. Instead, float tanks typically incorporate other effective disinfection methods like ozone or ultraviolet (UV) light to ensure water safety.

Who is responsible for regulating float tanks in the US?

In the US, there is no single national pool code for float tanks. Regulations are primarily decided at the state and provincial levels, with counties and cities often adding their own rules [https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/]. This fractured system means that local health departments are the primary agencies responsible for approving and auditing float centers.

What is the purpose of the CDC's Model Aquatic Health Code for float tanks?

The CDC's 2023 Model Aquatic Health Code (MAHC) provides recommendations for floatation tanks, serving as a suggested code for health departments to use when regulating pools and other recreational waters [https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf]. Its purpose is to offer evidence-based guidelines for safe operation and maintenance, helping to standardize best practices even within a varied regulatory environment.

When were the North American Float Tank Standards last updated?
