Wellness centers offering float therapy must navigate a complex and often inconsistent landscape of regulations. There is no single national pool code in the United States or Canada that governs float tanks. Instead, rules are decided at state, provincial, county, and city levels, leading to significant variations in what is required for approval. The Floatation Tank Association (FTA) has developed the 2025 North American Float Tank Standards to guide operators on best practices for quality, sanitation, and safety. Health departments often lack specific codes for float centers, sometimes categorizing them as pools, spas, tattoo parlors, or even hair salons. This can lead to the application of rules, such as those in the 2023 Model Aquatic Health Code (MAHC), which may not be suitable for the unique environment of a float tank.

What are the Current Float Tank Regulations?

Current float tank regulations are highly localized, meaning there is no single set of rules that applies across the entire United States or Canada. Instead, each state, province, county, and city can have its own specific requirements for operating a float center. This fragmented system means that the process and specifics for getting float tanks approved can differ greatly depending on the location.

The absence of a large, sweeping national pool code means local health departments often interpret existing regulations, or lack thereof, when dealing with float centers. In our analysis, this often leads to float centers being grouped with other facility types that don't quite fit. The Floatation Tank Association (FTA) has recognized this challenge. Its Sanitation and Regulations Committee has officially updated the North American Float Tank Standards for 2025. These standards aim to provide a set of best practices for quality, sanitation, and safety for float tank operations. These recommendations are based on current evidence and decades of operational experience, dating back to the commercial float tank's invention in the 1970s. For jurisdictions without existing float tank standards, these guidelines offer a valuable resource. We recommend reviewing the Floatation Tank Association standards to understand these best practices.

Beyond the FTA's guidelines, other organizations contribute to industry standards. NSF International, for example, creates product safety standards and certifications. Their NSF/ANSI/CAN 50 Standard for recreational water facilities includes specific language for float tanks. This standard can be purchased and offers another layer of guidance for operators and health departments. Furthermore, the Model Aquatic Health Code (MAHC) aims to develop a suggested code for health departments to use when regulating pools. The 2023 version of the MAHC includes regulations for floatation tanks, offering recommendations for their operation and maintenance. These recommendations, from the Centers for Disease Control and Prevention (CDC), highlight key aspects of safely managing floatation tanks.

Despite these efforts to create industry-specific guidelines, the local nature of regulation means that operators must still engage directly with their local health departments. This direct engagement is often the most effective way to understand the regulations that apply to a specific float center. The Floatation Tank Association actively tries to keep track of these diverse regulations and encourages operators to share any updated codes they find to help maintain an up-to-date resource. Understanding this varied regulatory landscape is the first step for any wellness center looking to offer float therapy.

The Role of State and Local Agencies

The primary authority for float tank regulation rests with state, provincial, county, and city health departments. Each of these governmental bodies can implement its own unique set of rules. This means that while some similarities might exist between codes, there can also be fundamental differences, even in areas like ideal pH levels for water quality. This fractured system means that a float center in one county might face entirely different requirements than one just across the county line.

Industry Best Practices and Standards

Organizations like the Floatation Tank Association (FTA) work to establish industry-wide best practices. The 2025 North American Float Tank Standards are a testament to this effort, offering comprehensive recommendations for commercial float tank operation. These standards cover aspects of sanitation, safety, and overall quality. They are supported by an appendix that explains the research and reasoning behind the recommendations, along with supporting documentation. Adhering to these standards can help operators demonstrate a commitment to safety and quality, even in the absence of specific local codes.

Certification and Code Inclusion

NSF International's NSF/ANSI/CAN 50 Standard plays a role in certifying products and facilities related to recreational water. The inclusion of float tank specific language in this standard provides an additional layer of recognized guidelines. Similarly, the CDC's Model Aquatic Health Code (MAHC) is a significant resource. The 2023 MAHC includes specific regulations for floatation tanks, offering health departments a framework to develop their local codes. These guidelines provide a foundation for understanding the CDC's recommendations for safe operation and maintenance.

How Do Health Departments Classify Float Tanks?

Health departments often face a challenge when it comes to classifying float tanks because most existing regulations were not written with float therapy in mind. As a result, local health departments may categorize float centers in various ways, including as pools or spas, tattoo parlors, or even hair salons. This happens because many health departments do not have specific codes or regulations tailored directly for float centers.

The lack of specific float tank regulations means that approval often depends on how a local health official interprets existing codes. For example, a float center might be treated like a swimming pool, even though the environments and operational requirements are vastly different. When we compare float tanks to traditional pools, we see that floatation refers to a meditative activity where users float in a high-density Epsom salt solution within a dark, quiet environment. This experience is distinct from swimming pools and other recreational water, which raises questions about the necessity and effectiveness of various disinfection methods. The North American Float Tank Standard, originally written in February 2017, explicitly states that placing float tanks in the same category as pools or spas ignores their unique nature. This can lead to rules that make no sense for a small, saline environment. 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 directly. We have seen that local contact is key to getting clear answers.

In some cases, health departments may classify float tanks based on the water's chemical composition or the nature of the service provided. For instance, if a health department focuses on the water aspect, it might default to pool or spa regulations. If it focuses on personal services, it might look to rules for tattoo parlors or salons. This ambiguity can be a source of frustration for float center operators, but understanding this potential for varied classification is crucial for preparing for health department inspections and approvals. The Floatation Tank Association actively collects information on how different states and counties regulate float centers, including examples from places like Anchorage, Southern Nevada, and Lafayette, Louisiana, where specific codes exist. Our experience shows that proactive engagement with local authorities and presenting a clear case for the unique nature of float tanks can help guide their classification process.

Challenges of Misclassification

When float tanks are misclassified, it can lead to inappropriate regulations being imposed. Applying pool codes, for instance, might result in requirements that are impractical or even detrimental to the float experience. The unique characteristics of float tanks, such as their small volume of highly saline water, differ significantly from large, chlorinated swimming pools. The North American Float Tank Standard highlights that equating pools and spas with floatation tanks can create unintended negative consequences for the floater's health and place unfair and unnecessary burdens on the float tank operator.

Strategies for Engagement

To navigate these classifications, float center operators should be prepared to educate their local health department officials. Providing information about the specific design, water treatment processes, and operational protocols of float tanks can help health officials understand their distinct nature. Emphasizing the high salinity of the water, which inhibits pathogen growth, and the use of advanced disinfection methods like ozone or UV, can differentiate float tanks from traditional recreational water facilities. This proactive approach can help steer the health department toward a more appropriate regulatory framework.

Local vs. Statewide Regulations

While some states, like Connecticut, Illinois, and New York, have some level of statewide regulations or guidance, many others, such as Arkansas, Louisiana, and Rhode Island, do not have readily available statewide regulations for float tanks. In these areas, the responsibility falls entirely on county and city health departments. This means that operators in states without statewide codes must be even more diligent in contacting their local health departments. For example, in California, multiple local and county regulations exist, requiring a direct call to the local department of health for information.

What Happens When a Float Tank is Regulated Like a Pool?

When a health department decides to regulate a float tank like a pool, it means that float centers must follow the general pool and spa codes. This approach can lead to significant challenges because many pool regulations are not designed for the unique environment of a float tank. While health departments often realize that applying all pool codes would lead to absurd rules—like requiring a "No Diving" sign or a lifeguard on duty for a float tank—even less obvious rules can conflict with float tank operation.

One of the most common pool regulations is "continuous filtration," which requires the pump to run all the time. This requirement, when applied to a float tank, can be at odds with providing a truly sensory-reduced environment for floatation. Floatation refers to a meditative activity where users float in a high-density Epsom salt solution in a dark, quiet environment. The goal is to reduce external stimulation, including sound and light. A continuously running pump can introduce unwanted noise and vibration, disrupting the very purpose of float therapy. We find that this type of regulation completely overlooks the inherent characteristics that are important to float tank safety and the user experience. The North American Float Tank Standard, written in February 2017, clearly states that equating pools and spas with floatation tanks may create unintended negative consequences for the health of the floater and place unfair and unnecessary burdens on the float tank operator.

The fundamental difference lies in the water chemistry and usage patterns. Float tanks contain a saturated solution of magnesium sulfate, which has a specific gravity of 1.23 to 1.3. This high salinity naturally inhibits the growth of many pathogens. Unlike public pools with high bather loads and constant water agitation, float tanks typically see individual users for limited periods, followed by a dedicated filtration and disinfection cycle. Applying rules meant for large, communal swimming environments to these small, personal, and highly saline tanks often creates regulations that make no sense. For example, maintaining specific chlorine levels might be mandated, even though float tank systems rarely use chlorine, relying instead on other effective disinfection methods like ozone or ultraviolet (UV) treatment. Successfully navigating this requires operators to advocate for the distinct nature of their facilities, explaining why blanket pool rules are inappropriate and how float tanks achieve safety through different, yet equally effective, means.

Inappropriate Rules and Their Impact

The imposition of pool-specific rules can result in costly and unnecessary modifications for float centers. For instance, requiring certain deck materials or shower facilities designed for public swimming pools might not be practical or financially feasible for a float studio. These rules do not account for the small, saline environment of a float tank. The costs associated with complying with such irrelevant regulations can become an unfair burden on float tank operators, potentially hindering the growth of wellness centers offering this unique therapy.

Understanding the Unique Environment

Float tanks are designed for reduced external stimulation, including sound, touch, and light. The water temperature is kept at approximately 92–96°F / 33.3–35.6°C, which is skin-temperature neutral, further enhancing the sensory deprivation experience. This controlled environment, combined with the high salt concentration, means that the risks and operational requirements are fundamentally different from a public swimming pool. Health departments need to understand these distinctions to avoid imposing regulations that are counterproductive to the purpose and safety of float tanks.

Advocating for Specific Regulations

Operators must be prepared to educate health officials on the unique aspects of float tanks. This includes explaining the disinfectant properties of the Epsom salt solution, the advanced filtration systems used, and the low bather load. Highlighting these differences can help health departments develop more appropriate, float-tank-specific regulations, rather than simply defaulting to pool codes. Showing how float centers ensure safety and sanitation through methods tailored to their environment is key to avoiding misapplication of rules.

What are the Risks if Float Tanks are Not Maintained Properly?

If floatation tanks are not maintained properly, significant health risks can arise due to the potential for pathogen survival and transmission. When the water solution used in floatation tanks is not treated correctly, harmful microorganisms can remain in the water, increasing the likelihood of disease. This is a critical concern, even though float tanks have inherent properties that can reduce some risks.

Float tanks contain a saturated solution of magnesium sulfate, commonly known as Epsom salt. This solution has a specific gravity of 1.23 to 1.3, making it incredibly dense, which allows users to float effortlessly. The water temperature is maintained at approximately 92–96°F / 33.3–35.6°C, a range that is often skin-temperature neutral. While the high salinity of the Epsom salt solution does inhibit the growth of many pathogens, it does not eliminate all risks. Pathogens can still survive in an improperly treated solution, leading to potential health issues for floaters. The Centers for Disease Control and Prevention (CDC) provides recommendations for the operation and maintenance of floatation tanks, emphasizing the need for proper treatment to mitigate these risks. For more detailed information, operators can refer to the CDC's 2023 Model Aquatic Health Code (MAHC). For more details, see CDC's Model Aquatic Health Code recommendations.

The primary risk areas include skin infections, ear infections, and gastrointestinal illnesses if contaminated water is ingested. These risks are amplified if the water supply itself is not safe. Water used by floatation tank facilities should always be from a potable source, meaning it is safe for drinking. This ensures that the water entering the tank is already free from major contaminants. Since float tank systems rarely use chemicals like chlorine, which is common in traditional pools, other effective disinfection methods are essential. Without proper disinfection, the unique environment of a float tank, designed for relaxation and sensory reduction, could inadvertently become a breeding ground for harmful bacteria or fungi. This underscores the importance of rigorous sanitation protocols beyond just the high salt content.

Pathogen Survival

Despite the high salt concentration, some pathogens can still survive in float tank water if not properly managed. Organisms like Pseudomonas aeruginosa, which can cause skin rashes and ear infections, or other bacteria and fungi, can find ways to persist. The warm water temperature, while comfortable for users, can also be conducive to microbial growth if not adequately disinfected. Therefore, relying solely on salinity is insufficient for ensuring public health.

Importance of Potable Water

Using a potable water supply is a foundational step in float tank sanitation. Starting with clean, safe water reduces the initial microbial load and minimizes the introduction of contaminants into the float solution. This practice is a basic public health measure that applies to all recreational water facilities, including float tanks. Ensuring the water source is safe is the first line of defense against waterborne illnesses.

The Need for Effective Disinfection

Because float tanks typically avoid chlorine to preserve the integrity of the Epsom salt and provide a non-irritating experience, other robust disinfection methods become crucial. The risk of disease transmission increases significantly if these alternative disinfection methods are not incorporated or maintained. Operators must understand that the unique nature of float tanks demands specific and effective sanitation strategies.

What Disinfection Methods are Effective for Float Tanks?

Since float tank systems rarely use chemicals like chlorine, which is a common disinfectant in traditional swimming pools, other effective disinfection methods are critically needed to ensure safety. The high concentration of magnesium sulfate in float tanks, while inhibitory to some pathogens, is not a complete disinfectant on its own. Therefore, operators must incorporate robust alternative methods to reduce the likelihood of pathogen transmission.

Ozone or ultraviolet (UV) disinfection are highly recommended and widely adopted methods for float tank sanitation. These technologies are effective at neutralizing bacteria, viruses, and other microorganisms without introducing harsh chemicals into the float solution. Ozone, a powerful oxidant, breaks down contaminants and pathogens. UV light, on the other hand, works by disrupting the DNA of microorganisms, preventing them from reproducing and causing harm. When we look at the Centers for Disease Control and Prevention’s (CDC’s) recommendations, they highlight these methods as key for operation and maintenance. The CDC's 2023 Model Aquatic Health Code (MAHC) emphasizes the importance of these effective disinfection strategies for floatation tanks, which are also known as float rooms, pods, spas, chambers, isolation tanks, or sensory deprivation tanks. We know that proper sanitation is fundamental to the float experience. You can read more about the basics of float tank sanitation to understand these methods.

Beyond ozone and UV, float centers often employ multi-stage filtration systems to physically remove particulate matter and microorganisms. These systems typically include micron filters that can trap very small particles. The combination of physical filtration with chemical-free disinfection methods like ozone or UV provides a comprehensive approach to maintaining water quality. Furthermore, regular water testing is essential to monitor pH levels, alkalinity, and the efficacy of the disinfection system. This proactive monitoring ensures that the chosen methods are consistently working to keep the float solution clean and safe for every user. The high density of the Epsom salt solution itself also contributes to water quality by causing contaminants to float on the surface, making them easier to skim and remove. The unique environment of a float tank, designed for reduced external stimulation, necessitates a disinfection strategy that is both highly effective and minimally intrusive to the user experience.

Ozone Disinfection

Ozone (O3) is a powerful disinfectant that can destroy bacteria, viruses, and protozoa more effectively than chlorine. It is generated on-site and introduced into the float tank's filtration system. Ozone oxidizes organic and inorganic contaminants, breaking them down into harmless byproducts. Because it quickly reverts to oxygen, it leaves no chemical residue in the water, which is ideal for a sensory deprivation environment.

Ultraviolet (UV) Disinfection

UV disinfection systems use germicidal UV lamps to expose float tank water to specific wavelengths of light. This light damages the genetic material of microorganisms, preventing them from replicating and causing infection. UV systems are highly effective, chemical-free, and do not alter the water's taste, odor, or pH. They are typically installed in the filtration loop, treating the water as it circulates through the system.

Multi-Stage Filtration and Testing

In addition to ozone and UV, float tanks employ advanced filtration. This often includes fine-micron filters capable of removing hair, skin cells, and other particulates. Regular and thorough water testing is crucial to confirm the effectiveness of these systems. Operators monitor parameters such as pH, alkalinity, and the presence of any microbial indicators to ensure the water remains pristine. This comprehensive approach, combining physical filtration with advanced disinfection, is vital for float tank safety.

How Can Float Centers Work with Health Departments for Approval?

Working effectively with health departments for approval requires a proactive and educational approach, especially given the varied and often non-existent specific regulations for float tanks. Understanding how your local health department operates is crucial for a smooth approval process. Since almost none of the existing pool rules explicitly address float tanks, their regulation often becomes a matter of the personal opinion of your local health department official.

To navigate this, float centers should be prepared to highlight the unique nature of float tanks, which fundamentally differs from pools and spas, to avoid inappropriate regulations. This involves educating officials on the specific design, water chemistry, and sanitation protocols unique to float therapy. For example, explaining that float tanks use a saturated solution of magnesium sulfate with a specific gravity of 1.23 to 1.3, which naturally inhibits many pathogens, can help differentiate them from chlorinated pools. We have found that presenting a well-researched case can make a significant difference. The Floatation Tank Association, located at 3126 W Cary St PMB 117, Richmond, VA 23221-3504, is a resource for operators seeking guidance on these matters. We recommend reviewing the Float Tank Solutions approval guide for practical advice on working with health departments.

Operators should initiate contact with their local health department early in the planning stages of their float center. This allows for open communication and the opportunity to present detailed plans for water treatment, ventilation, and facility design. Providing information on industry best practices, such as the 2025 North American Float Tank Standards and recommendations from the CDC's 2023 Model Aquatic Health Code (MAHC), can lend credibility to your operational plans. It is also helpful to be prepared to explain why certain traditional pool regulations, like continuous filtration or specific chemical levels, are either unnecessary or counterproductive in a float tank environment. By demonstrating a thorough understanding of sanitation and safety, float center operators can build trust with health officials and guide them toward a fair and appropriate regulatory framework.

Early Engagement and Education

Starting conversations with the health department early in the planning phase is critical. This proactive step allows operators to present their facility plans, water treatment protocols, and safety measures before any misunderstandings arise. Educating health officials about the unique aspects of float tanks—such as the high salt concentration, low bather load, and advanced chemical-free disinfection methods like UV and ozone—can prevent misclassification and the application of inappropriate pool codes.

Presenting Industry Standards

Referencing established industry standards and guidelines can significantly strengthen a float center's case. The 2025 North American Float Tank Standards provide a comprehensive set of best practices that demonstrate a commitment to quality and safety. Additionally, drawing on recommendations from the CDC's Model Aquatic Health Code (MAHC) regarding floatation tanks can show that the center is aligning with recognized public health guidance, even if specific local codes are lacking.

Documenting Operations and Safety

Maintaining detailed records of water testing, maintenance schedules, and disinfection processes is essential. These records serve as evidence of diligent operation and adherence to safety protocols. When health officials see a well-documented and transparent approach to sanitation, it fosters confidence in the float center's commitment to public health. Being able to clearly explain and demonstrate these practices can streamline the approval process and address any concerns the health department may have.

Frequently Asked Questions

What is the Floatation Tank Association?

The Floatation Tank Association (FTA) is an organization that supports the float community. It manages industry standards and provides resources for float center operators. The FTA's Sanitation and Regulations Committee officially updated the North American Float Tank Standards for 2025, which outlines best practices for quality, sanitation, and safety. The FTA also hosts events like the Float Conference 2026 in Norfolk, VA.
