But how do you choose a floatation tank that suits your needs and preferences? What are the technical specifications you need to look out for when buying or renting a floatation tank? In this blog post, we will answer these questions and provide you with some useful tips and information to help you make an informed decision.
What is a Floatation Tank?
A floatation tank is a lightless, soundproof tank that is partially filled with water and a high concentration of Epsom salt (magnesium sulfate). The water is heated to match your skin temperature (around 35°C or 95°F) and the salt makes you buoyant so that you can float effortlessly on the water surface. The tank is usually equipped with an air ventilation system, an underwater light, a music system and an emergency button. Some tanks also have a remote control that allows you to adjust the settings from outside the tank.
The purpose of a floatation tank is to create a sensory-deprived environment that minimizes external stimuli such as light, sound, touch, gravity and temperature. This allows your brain to enter a state of deep relaxation and meditation, where you can access your subconscious mind and experience enhanced awareness, creativity and insight.

What are the Technical Specifications You Need to Look Out for?
When choosing a floatation tank, there are several technical specifications you need to consider, such as:
Size and shape: When choosing a floatation tank, you need to consider the size and shape of the tank as essential features. They can make a big difference in your comfort, space and claustrophobia. Smaller tanks can feel cramped and restrictive, while larger tanks can give you more room and flexibility. You can even float with a partner in some tanks. The shape of the tank can also affect your mood and expectations. Basic shapes can seem dull and simple, while organic shapes can create a soothing and inviting atmosphere. The Exo Floatation Pod has the most spacious interior of any Pod on the market and a natural, elegant shape.
Water depth and salinity: The water depth is typically between 10 and 12 inches (25 and 40 cm) and the salinity is near its saturation point (around 1.27 specific gravity). This means that you will be floating on top of the water without touching the bottom or the sides of the tank. The high salinity also has some health benefits, such as detoxifying your skin, relaxing your muscles and replenishing your magnesium levels.
Heating system: A vital feature of the floatation tank is the heating system, which keeps the water temperature steady and matching your skin temperature. This is crucial for creating the feeling of weightlessness and blurring the boundaries of your body. The Exo uses an inline heater, which is easy to maintain and has a high heating output. This is better than other systems that use under tank heaters. The Exo also monitors the temperature in 3 places to ensure ultimate accuracy.
Filtration system: The filtration system of the floatation tank is essential for keeping the water clean and hygienic. The filtration system usually consists of several components, such as pumps, filters, UV lights and disinfectants. The filtration system should be able to remove any impurities, bacteria, fungi or viruses from the water after each use and every use. The Exo Floatation pod unlike many other floatation pods, empties between every session, ensuring all of the water is filtered and sterilised for each customer. See our blog on Why a float tank should fill and empty.
Filter Size: Another important feature of the filtration system is the size of the filters, which determines how small the particles that can be removed are. The smaller the filter size, the better the filtration efficiency. The Exo Floatation pod uses two filters with a micron size of 1, which means they can capture particles as small as 1 micrometre or 0.001 millimetre 1. It also uses a course pre filter to remove larger particulate.
Hydroxyl Radicals: The Exo Floatation pod also uses a combination of silver stabilized hydrogen peroxide (H2O2) and photo catalytic ultraviolet C (UVC) light to disinfect the water. Silver stabilized H2O2 is a powerful oxidant that can kill bacteria, fungi and viruses without leaving any harmful residues. Photo catalytic UVC light can produce H2O2 from water and oxygen, and also destroy organic pollutants and microorganisms. The Exo Floatation pod uses both methods to ensure the water is clean and safe for every customer.
Ventilation system: The floatation tank needs a ventilation system to keep the air inside the tank fresh and avoid moisture or condensation problems. The ventilation system can be either natural or mechanical, depending on how much air flow is needed. Natural ventilation systems use vents or openings in the tank to let the air in and out. Mechanical ventilation systems use fans or blowers to force the air in and out but can make noise during a session and disturb the user. The Exo Floatation tank uses a natural ventilation system, and has a very cozy float environment because the Pod is empty before the customer floats, which lowers humidity.
Lighting system: The lighting system of the floatation tank is optional but can enhance your floating experience by creating different moods or atmospheres. The lighting system can be either internal or external, depending on where the lights are installed. Internal lighting systems are located inside the tank and can be controlled by switches or buttons within your reach. External lighting systems are located outside the tank and can be controlled by remote controls or timers from outside the tank. The exo uses lighting to allow customers to relax as quickly as possible at the start and end of a session, it matches natures lighting of sunset and sunrise, but also has other custom lighting modes available. The Exo also regulates the room lighting so that the customer can always have visibility in the room. It does this by activating a sensor when the door is opened.
Sound system: The sound system of the floatation tank is also optional but can help you relax or stimulate your senses by playing music or sounds of your choice. The sound system can be either wired or wireless, depending on how the sound is transmitted to the tank. Wired sound systems use speakers or headphones that are connected to a sound source by cables or wires. Wireless sound systems use Bluetooth or Wi-Fi technology to stream sound from a device to the tank. With its integrated sound transducers, the Exo transforms the whole pod into a speaker that delivers immersive and all-encompassing sound.
How to Compare Different Floatation Tanks: The only way to find out which floatation tank or Pod suits you best is to experience a float yourself. Test all the systems and decide which one gives you the most relaxing and enjoyable float.
Here are some factors to keep in mind when comparing different floatation tanks:
Quality and durability: The quality and durability of the floatation tank depend on the materials, design and craftsmanship of the tank. You should look for a tank that is made of high-quality, durable and corrosion-resistant materials, such as fiberglass, acrylic or stainless steel and titanium. You should also look for a tank that has a sturdy, stable and ergonomic design that can withstand wear and tear and provide comfort and safety, non-slip flooring, grab handles for entry and exit. You should also check the warranty and service plan of the tank to ensure that you can get support and maintenance if needed.
A floatation tank is a harsh environment due to the high salt concentration and chemicals that can be used to disinfect the water. These factors can damage or corrode the GRP material if it is not of high quality. The Exo Float uses only the highest grade materials and workmanship in the United Kingdom to produce GRP floatation tanks that can withstand these harsh conditions. The Exo Float uses premium resin and fibres, as well as advanced manufacturing techniques, to ensure the GRP floatation tanks are of the highest quality and durability. The Exo Float also offers a 10-year warranty on the GRP shell, giving you peace of mind and confidence in your investment.
Price and value: The cost and quality of the floatation tank are determined by the features, specifications and performance of the tank. You should look for a tank that offers the best quality for your money, meaning that it satisfies your needs and expectations without exceeding your budget but also ensuring your business can operate without interruption and downtime. You should also shop around and compare the costs of different tanks from different brands and suppliers to find the best offer. You should also consider the running costs of the tank, such as electricity, water, salt, filters and disinfectants. It’s important for any service business to consider the trade-off between the initial investment and the potential loss of trade. A single day’s trading for a floatation tank can earn anywhere between £500 – £800 per day. This can be worsened by slow support or downtime, another reason exo float provide remote support for fast accurate diagnosis to resolve problems.
Reviews and ratings: The reviews and ratings of the floatation tank can tell you two things: how the customers who float in the tank enjoy their experience, and how the customers who buy the tank appreciate their service. You should look for a tank that has positive reviews and ratings from both types of customers, who have experienced or owned the tank. You should also look for reliable and truthful reviews and ratings from trustworthy sources, such as websites, blogs, magazines or forums. You should also avoid fake or deceptive reviews and ratings that are influenced or paid by the manufacturers or sellers.
