Are Flotation Tanks Sanitary?

We will discuss how hygienic and sanitary floatation tanks are and the current measures and practices in place.

Sensory deprivation tanks, also known as flotation tanks, offer a unique experience of relaxation and mental rejuvenation. But despite the appeal of weightlessness and peace, a crucial question often arises: Are flotation tanks sanitary and hygienic? In this article, we will discuss the cleanliness of flotation tanks and explore the measures taken to ensure a safe and hygienic environment for users.

Understanding Flotation Tanks

Before we dive into the cleanliness aspect, let's briefly understand what flotation tanks are.


These tanks are filled with warm water mixed with Epsom salts, creating a buoyant environment where users float effortlessly. The water is kept at skin temperature, and the tanks are designed to minimise sensory input, allowing users to enter a state of deep relaxation.

Sanitation Practices

One of the potential concerns for those considering a flotation tank experience is cleanliness. After all, you'll be spending time in a confined space filled with water. Rest assured, reputable flotation tank centres adhere to strict sanitation practices to ensure your safety and comfort.

1.      Filtration Systems: Flotation tank facilities are equipped with advanced filtration systems that continuously purify the water. These systems remove impurities, bacteria, and other contaminants, maintaining a high level of cleanliness throughout your session. The best systems filter particles as small as 1 micron, that’s 100 times smaller than a human hair.


2.      UV Sterilization: In addition to filtration, many flotation tank centres use UV sterilisation to eliminate any remaining bacteria and pathogens in the water. UV light is highly effective at destroying microorganisms, leaving the tank water exceptionally clean and hygienic.


3.      Regular Water Testing: To ensure the water remains safe for use, flotation tank centers conduct regular water testing. Parameters such as pH levels, disinfectant concentration, and microbial content are monitored and adjusted as needed to meet hygiene standards.


4.      Personal Hygiene Practices: Users are typically required to shower before entering the tank to remove oils, lotions, and other substances from their skin. Additionally, most centres provide users with amenities such as towels and earplugs to maintain hygiene standards.

Client Responsibilities to Enhance Cleanliness and Hygiene


While flotation tank facilities take significant measures to ensure cleanliness, there are also steps that clients can take to contribute to the hygienic environment.


1.      Shower Beforehand: It's recommended to shower before entering the flotation tank to rinse off any oils, lotions, or dirt that could contaminate the water. Clean skin helps maintain water quality and ensures a more pleasant experience for everyone.


2.      Ear Protection: Most flotation tank centres provide earplugs to protect your ears from water entering during the session. Using earplugs not only enhances your comfort but also reduces the risk of introducing bacteria into the tank.


3.      Seal Open Wounds: If you have any open wounds or skin lesions, it's best to seal them with a plaster or Vaseline before entering the pod. Open wounds can increase the risk of infection, so covering them before entering the pod is highly recommended. Due to the high salt content of the water, applying Vaseline is also recommended to reduce any stinging sensations upon entry to the pod.

3 Benefits of Sanitary Practices


1.      Preventing Microbial Growth: By implementing stringent cleaning and disinfection protocols, flotation tank centres minimise the risk of microbial growth in the water. This helps prevent potential infections or skin irritations for users.

2.      Ensuring User Comfort: A clean and hygienic environment enhances the overall experience for users, allowing them to relax without concerns about cleanliness or safety.

3.       Promoting Repeat Business: Maintaining high standards of cleanliness not only ensures the well-being of users but also contributes to customer satisfaction and loyalty. Satisfied customers are more likely to return for future sessions and recommend the experience to others.



In conclusion, the cleanliness and hygiene of flotation tanks are paramount considerations for ensuring a safe and enjoyable experience for users. Through advanced filtration systems, UV sterilisation, and rigorous cleaning protocols, reputable flotation tank centres maintain a high standard of sanitation. These practices not only prevent microbial growth and promote user comfort but also contribute to customer satisfaction and loyalty.


While concerns about the transmission of infections and the presence of contaminants may arise, it's essential to recognise the transparent efforts made by flotation tank facilities to address these worries and prioritise the safety of their clients. With proper sanitation practices and client education, flotation tank therapy continues to offer a serene and rejuvenating retreat for those seeking relaxation and mental rejuvenation.
