Quick Answer

Float tanks contain a saturated solution of magnesium sulfate with a specific gravity of 1.23 to 1.3, kept at 92–96°F (33.3–35.6°C) to allow floating (https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf).
The Floatation Tank Association (FTA) updated its North American Float Tank Standards in 2025 to ensure quality, sanitation, and safety (https://www.floatation.org/standards-regulations).
Many health departments lack specific float tank codes, often classifying them as pools, spas, tattoo parlors, or hair salons (https://www.floatation.org/standards-regulations).
Pathogens can survive in improperly treated float tank water, increasing disease risk if effective disinfection methods like ozone or UV are not used (https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf).

Float tanks offer a unique relaxation experience by allowing users to float in a highly saturated magnesium sulfate solution within a reduced-stimulation environment. However, ensuring proper hygiene and sanitation in these systems is critical to prevent the spread of disease. Many health departments face challenges in regulating float tanks because there is no single, national standard across the United States or Canada. Instead, regulations often vary by state, province, county, or even city, leading to float centers being classified under codes for pools, spas, or even unrelated businesses like tattoo parlors. The Floatation Tank Association (FTA) has actively worked to address this, releasing updated North American Float Tank Standards in 2025 to provide best practices for quality, sanitation, and safety in commercial float operations Floatation Tank Association Standards and Regulations. When water in these tanks is not properly treated, pathogens can survive, increasing the risk of disease transmission. Therefore, effective disinfection methods, such as ozone or ultraviolet (UV) treatment, are essential, especially since float tank systems rarely use traditional chemicals like chlorine.

What are Float Tanks and How Do They Work?

Floatation tanks, also known as float tanks, float rooms, pods, spas, chambers, isolation tanks, or sensory deprivation tanks, are specialized tubs designed for relaxation therapy. They contain a specific water solution and create an environment with minimal external stimulation.

The Unique Solution

The core of a float tank is its water solution. This solution is not plain water; it is a saturated mix of magnesium sulfate, commonly known as Epsom salt. This high concentration of salt is what allows a person to float effortlessly. The specific gravity of the solution typically ranges from 1.23 to 1.3. This density is much higher than regular water, providing buoyancy that supports the body. The water used by floatation tank facilities should always come from a potable source. This ensures the initial water quality is safe before any treatment processes begin.

Optimal Temperature and Environment

Float tanks maintain a carefully controlled temperature. The water is kept at approximately 92–96°F (33.3–35.6°C). This temperature is close to skin temperature, which helps reduce the sensation of touch and further enhances the feeling of weightlessness. Beyond temperature, the environment inside a float tank is designed to minimize sensory input. This means the tanks are typically dark and quiet, reducing light and sound. The goal is to create a peaceful space where individuals can experience deep relaxation without distractions. This unique combination of buoyancy, temperature, and sensory reduction allows users to enter a meditative state, promoting mental and physical well-being. The design and operation of these tanks are distinct from other recreational water facilities, which is a key factor in how they are regulated.

Decades of Operational Experience

The concept of commercial float tanks dates back to the 1970s. Over these decades, operators have gained significant experience in managing these unique environments. The recommendations for best practices, including sanitation and safety, are built upon this extensive operational knowledge and current scientific evidence. Understanding these foundational aspects of float tanks is crucial for appreciating the complexities of their hygiene and regulation. The very nature of the high-density salt solution and the controlled environment demands specific consideration for maintaining cleanliness and preventing health risks.

What Are the Risks of Unmaintained Float Tanks?

If float tanks are not properly maintained, they pose significant health risks to users. The primary danger stems from the potential for pathogens to survive and spread within the water solution.

Pathogen Survival and Disease Transmission

When the water solution in floatation tanks is not treated correctly, harmful pathogens can survive. These pathogens can then be transmitted from one user to another, leading to an increased risk of disease. Unlike swimming pools that frequently use chlorine, float tank systems rarely rely on this chemical for disinfection. This difference means that float tanks require other effective disinfection methods to reduce the likelihood of pathogen transmission. The Centers for Disease Control and Prevention (CDC) emphasizes the importance of proper operation and maintenance to prevent such risks. The CDC's 2023 Model Aquatic Health Code (MAHC) provides recommendations for ensuring floatation tank safety.

Unique Disinfection Challenges

Float tanks present unique disinfection challenges compared to traditional pools or spas. The high concentration of Epsom salt, while beneficial for buoyancy, can affect the efficacy of some disinfectants. Additionally, the enclosed nature of many float tanks means that airborne contaminants or those introduced by users can accumulate if the filtration and disinfection systems are inadequate. The goal of float therapy is to reduce external stimulation, which means users are often immersed for extended periods. This prolonged contact with the water highlights the necessity of stringent hygiene protocols. Without these, the very environment designed for wellness could become a source of illness. We understand the importance of maintaining water quality, which is why we emphasize the need for robust sanitation practices.

Consequences of Poor Maintenance

The consequences of poor float tank maintenance can range from minor skin irritations to more serious infections. While specific cases of widespread outbreaks directly linked to float tanks are not extensively documented in the provided research, the principle remains clear: any recreational water facility with inadequate treatment poses a risk. This is why organizations like the Floatation Tank Association (FTA) and the CDC provide guidelines. Their recommendations aim to prevent the conditions that would allow pathogens to thrive. Ensuring all float tank facilities use a potable water supply as their starting point is a fundamental step in preventing contamination. The overall health and safety of floaters depend heavily on the diligence and adherence to sanitation standards by float center operators.

How Are Float Tanks Regulated in the US and Canada?

The regulation of float tanks in the United States and Canada is a complex and often inconsistent process. There is no single, overarching national pool code that dictates how float tanks should be managed across either country.

Fragmented Regulatory Landscape

Instead of a unified system, almost all pool rules and regulations are determined at the state or provincial level. This means that each state or province has its own distinct set of rules. To make matters even more complicated, counties and cities can impose their own additional pool regulations on top of what the state or provincial rules already require. This results in a fractured regulatory system where the specific requirements for approving float tanks can vary significantly from one location to another. For example, some states like Connecticut, Illinois, Missouri, New Mexico, and Wisconsin may have specific guidelines or be working towards them, while others like Arkansas, Louisiana, and Rhode Island report no statewide regulations, requiring operators to check county-level rules.

Lack of Specific Float Tank Codes

A major challenge is that most existing pool and spa regulations do not specifically address float tanks. This absence of dedicated codes often leaves the regulation of float tanks open to the personal interpretation and opinion of local health department officials. A float center might be classified in various ways, such as a pool or spa, a tattoo parlor, or even a hair salon, depending on the local jurisdiction's approach. This inconsistent classification can lead to operators being asked to follow rules that are not practical or sensible for float tanks. The North American Float Tank Standard, updated by the Floatation Tank Association in 2025, aims to provide best practices for quality, sanitation, and safety, offering a valuable resource in this fragmented environment Floatation Tank Association Standards and Regulations.

Attempts at Standardization

Despite the challenges, efforts are underway to provide more consistent guidance. The CDC's 2023 Model Aquatic Health Code (MAHC) includes suggested regulations for floatation tanks. This code serves as a reference that health departments can use when developing their local regulations. Similarly, NSF International includes standard language for float tanks in its NSF/ANSI/CAN 50 Standard for recreational water facilities. These resources provide a framework, but local adoption and implementation remain inconsistent. Our analysis shows that finding the applicable regulations often requires direct contact with city, county, or state health departments, as statewide codes are not always readily available or specific to float tanks. This situation underscores the ongoing need for clearer, more consistent guidelines for float tank operations. Float Tank Solutions on Health Department Approvals explains that operators often face the challenge of convincing health officials that float tanks are distinct from pools, requiring a nuanced regulatory approach.

Why Do Health Departments Struggle to Classify Float Tanks?

Health departments often struggle to classify float tanks because these systems are fundamentally different from traditional swimming pools and spas. This distinction creates significant challenges when trying to apply existing regulations.

Unique Nature of Float Tanks

Float tanks are distinct from swimming pools and other recreational water facilities. They involve a meditative activity where users float in a high-density Epsom salt solution within a dark, quiet environment. This unique setup, characterized by a small, saline environment, sets them apart. The water temperature is specific, typically around 92–96°F (33.3–35.6°C), and the solution has a high specific gravity of 1.23 to 1.3. These inherent characteristics are crucial for the safety and operation of a float tank, but they are often overlooked when health departments attempt to categorize them.

Illogical Application of Pool Codes

In many jurisdictions without specific float tank standards, health departments initially try to regulate them like pools or spas. This approach can lead to illogical and impractical requirements. For example, applying all pool codes might demand absurd rules such as posting "No Diving" signs in front of each tank, which is clearly nonsensical given the tank's size and depth. Another common pool regulation, "continuous filtration," requires pumps to run all the time. This might not be suitable for float tanks where the goal is often a still, undisturbed environment for the floater.

"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. Doing so ignores the unique nature of floating, leaving out inherent characteristics important to float tank safety and enforces others that make no sense for the small, saline environment. 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," states the North American Float Tank Standard, written in February 2017 (https://dphhs.mt.gov/assets/publichealth/FCS/PublicSwimmingPools/NorthAmericanFloatTankStandard.pdf). This highlights the disconnect between existing pool regulations and the specific needs of float tank operations.

Personal Opinions and Burden on Operators

The lack of specific float tank regulations often means that their approval depends on the personal opinion of local health department officials. This subjectivity can lead to inconsistent application of rules and costly changes for float center operators. Operators might be forced to make modifications to their pump systems or facility layouts based on interpretations that do not align with float tank best practices. This places an unfair and unnecessary burden on businesses trying to provide a specialized wellness service. The ongoing discussion around the need for and efficacy of various disinfection methods for float tanks further complicates this classification issue. "Because float tanks are distinct from swimming pools and other recreational water, questions have been raised regarding the need for and efficacy of various disinfection methods," observed Angela Eykelbosh and Shelley Beaudet in their July 2016 paper, "Float Tanks: Considerations for Environmental Public Health" (https://ncceh.ca/sites/default/files/Float_Tanks_Considerations_EPH_July_2016.pdf). This ongoing debate underscores the need for tailored, evidence-based regulations that recognize the unique characteristics of float tanks.

What Disinfection Methods Are Recommended for Float Tanks?

Because float tanks rarely use traditional chemicals like chlorine to treat their water, other effective disinfection methods are crucial to ensure hygiene and reduce the risk of pathogen transmission. The goal is to maintain a clean and safe environment for all users.

Essential Disinfection Technologies

Since float tank systems do not commonly incorporate chlorine, operators must integrate other powerful disinfection technologies. Ozone and ultraviolet (UV) treatment are two primary methods recommended for effectively treating the water solution. Ozone is a strong oxidant that can kill bacteria, viruses, and other microorganisms. UV light works by disrupting the DNA of pathogens, preventing them from reproducing. Both methods are highly effective and can be used in conjunction with filtration systems to maintain water quality. The CDC's recommendations for floatation tank operation and maintenance highlight the importance of these advanced disinfection methods.

Potable Water Supply

A fundamental requirement for any floatation tank facility is to use a potable water supply. Potable water is water that is safe to drink, meaning it meets public health standards for quality. Starting with clean, potable water significantly reduces the initial pathogen load in the tank. This makes the subsequent disinfection processes, such as ozone or UV treatment, more effective and easier to manage. It is a baseline best practice to ensure quality, sanitation, and safety while operating float tanks in a commercial setting. Without a clean starting point, even the best disinfection systems can be overwhelmed.

Filtration and Ongoing Maintenance

Beyond disinfection, robust filtration systems are essential for float tanks. These systems remove physical contaminants, such as skin cells, hair, and other debris, that can be introduced by users. Regular filtration, combined with effective disinfection, creates a multi-barrier approach to water treatment. Operators must also follow a strict schedule for testing and maintaining the saltwater solution. This includes monitoring parameters like pH levels and the concentration of disinfectants (if any are used). The Floatation Tank Association's North American Float Tank Standards provide best practices for these operational aspects, drawing on decades of experience in the industry. Proper maintenance is not a one-time task but an ongoing commitment to ensuring the safety and cleanliness of the float environment. When we compare float tank needs to pool rules, it becomes clear that continuous filtration, while important, must be paired with specific disinfection methods tailored to the high-saline environment and enclosed nature of float tanks.

Where Can Operators Find Float Tank Standards and Resources?

Float tank operators have several key resources available to help them understand and implement best practices for hygiene, sanitation, and safety. These resources come from industry associations and public health organizations.

Floatation Tank Association Standards

The Floatation Tank Association (FTA) is a crucial resource for the float community. The FTA's Sanitation and Regulations Committee officially updated the North American Float Tank Standards in 2025. These standards represent recommendations for baseline best practices to ensure quality, sanitation, and safety when operating float tanks in a commercial setting. These recommendations are based on current evidence for float tanks and decades of operational experience, dating back to the invention of the commercial float tank in the 1970s. Operators can download the most recent version of these standards directly from the FTA website. The FTA also hosts the Float Conference, an annual event that serves as a platform for sharing information and best practices within the industry, with the 2026 conference scheduled for September 18-20 in Norfolk, VA (https://www.floatation.org/).

CDC and NSF International Guidelines

Beyond industry-specific standards, broader public health organizations also offer guidance. The Centers for Disease Control and Prevention (CDC) provides recommendations for the operation and maintenance of floatation tanks through its 2023 Model Aquatic Health Code (MAHC). The MAHC aims to develop a suggested code for health departments to use when regulating various recreational water facilities, including floatation tanks CDC Model Aquatic Health Code Quick Guide for Float Tanks. This quick guide for health departments and operators highlights key information from the MAHC. Additionally, NSF International, an organization focused on product safety standards and certifications, includes standard language for float tanks in its NSF/ANSI/CAN 50 Standard for recreational water facilities. These resources provide a scientific and public health perspective on float tank operations.

Local Health Department Engagement

Despite these broader guidelines, operators must still engage directly with their local health department agencies. As we discussed, not all health departments have specific codes or regulations for float centers. A float center may be classified under various categories depending on the locality. The most effective way to determine the applicable regulations is to visit the city, county, or state's health department website or contact them directly. The FTA also endeavors to collect and share information on existing regulations across many cities and counties in the US, encouraging operators to help keep this information up-to-date. This local engagement is vital for ensuring compliance and smooth operation, bridging the gap between national recommendations and specific regional requirements. We find that proactive communication with local officials helps streamline the approval process.

Frequently Asked Questions

What is the optimal temperature for float tank water?

Float tank water is maintained at an approximate temperature of 92–96°F (33.3–35.6°C). This specific temperature range is chosen because it is close to human skin temperature. The goal is to minimize the sensation of touch and temperature differences, which helps create an environment with reduced external stimulation for the floater (https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf). This precise temperature control is a key factor in the sensory deprivation experience.

Why don't float tanks typically use chlorine for disinfection?

Float tanks rarely use chemicals like chlorine for water treatment. This is partly due to the high concentration of magnesium sulfate (Epsom salt) in the water, which can affect the efficacy of chlorine or create unwanted chemical reactions. Instead, float tank systems incorporate other effective disinfection methods, such as ozone or ultraviolet (UV) light, to reduce the likelihood of pathogen transmission (https://www.naccho.org/uploads/downloadable-resources/quickguide-August2023-FloatationTanks-final.pdf). These alternative methods are well-suited to the unique chemical environment of float tanks.

Are there national regulations for float tanks in the US or Canada?

No, there is no single, large sweeping national pool code in the United States or Canada that specifically covers float tanks. Regulations are primarily decided at the state/provincial level, and often further refined by county and city rules. This results in a fragmented system where the specifics of getting float tanks approved can vary hugely from place to place (https://www.floattanksolutions.com/the-health-department-and-float-tanks-how-to-get-approved/). Many health departments lack specific codes for float centers, leading to varied classifications.

What is the Floatation Tank Association's role in setting standards?

The Floatation Tank Association (FTA) plays a significant role in developing and promoting best practices for float tank operations. The FTA's Sanitation and Regulations Committee officially updated the North American Float Tank Standards in 2025. These standards provide recommendations to ensure quality, sanitation, and safety for commercial float tank facilities (https://www.floatation.org/standards-regulations). The FTA leverages decades of operational experience and current evidence to inform these guidelines.

How can float center operators ensure their tanks meet hygiene standards?

Float center operators can ensure hygiene by following best practices from reputable sources. This includes using a potable water supply, incorporating effective disinfection methods like ozone or UV treatment, and maintaining robust filtration systems. Operators should also consult the Floatation Tank Association's North American Float Tank Standards, updated in 2025, and engage directly with their local city, county, or state health department for specific regulatory requirements (https://www.floatation.org/standards-regulations). Regular testing and maintenance of the saltwater solution are also critical components of a comprehensive hygiene strategy.
