Common Questions And Answers

What is a Floatation Chamber?
A Float Lab floatation chamber provides a light- and sound-free environment containing 12″ of solution consisting of water and about 1200 lbs of dissolved Epsom salt. The fluid temperature is maintained at external body temperature (around 95˚). Inside the Chamber, the participant floats effortlessly without gravitational requirements and neither sound nor light input to consider.


How do you clean the float rooms?
Our rooms are kept safe and sterile by use of the best float chamber cleaning systems in the industry built by Float Lab Technologies

Float Lab Technologies is the world's only NSF certified flotation chamber manufacturer and strives to provide the safest and most hygienic chambers possible.

The standards are those we have found necessary for reliability of operation, for safety, and for maintenance of a hygienic environment. Low cost of operation and safety are favored over low initial investment; if a more expensive item meets our standards and decreases the cost of operation we use it rather than a less expensive item that may be less reliable, unsafe or costly to operate in the long run. A cheaper item may end up generating far more cost in terms of unreliable operation, redesign cost, time spent on its maintenance, anxiety over its unsafe operation, and its potentially unhealthful effects on persons using the tank.

Who invented the first float tank?
John C. Lily.

How long have float tanks been around?
The first float tank was developed in 1954.  These involved full submersion in water and a breathing device that completely covered your face.  The first lay down, commercial tanks were invented in the early 70′s.

What if I am claustrophobic?
The thought of being in a dark space can be frightening to some. However, as with your eyes closed, total black does not create an enclosed, confined, limited or restricted feeling; it actually seems vast or unlimited. Our Chamber models are big enough to stand and walk around in. Remember, you are in complete control of your surroundings, so if need be, you can exit the Chamber at anytime.

Do I need to bring anything?
If you have longer hair, you may want to bring a comb.  Also, something to put your contact lenses into while you’re in the tank.  We provide towels, earplugs, body wash, and shampoo.

Do I get dehydrated from soaking for so long?

Can I drown if I fall asleep in there?
No. Some people fall asleep, but the water is so buoyant that you stay afloat.  The worst that can happen is getting woken up by a bit of salt water in your eyes.

How big is a Chamber?
The dimensions of our Float Lab Chambers are 5′ Wide 8′ Long x 7′ High.

Does it have other names?
Yes: Sensory Deprivation Tank, Float Tank, Flotation Tank, and Isolation Chamber.

Is it hard to do?
No. In fact, the less you do the better. It may take a couple sessions to get the hang of it.

Do I shower before using the Chamber?
Yes. To extend the life of the filtration system, showering beforehand is extremely important. Using the shower afterwards is also suggested to remove the coating of Epsom salt that is left on the skin and hair.

What do I wear while floating?
You don’t wear anything while floating.

How long do sessions last?
One or more hours. You can get out at any time.

Should I eat before floating?
A heavy meal beforehand is not suggested, however you don’t want to hear your stomach growling. Also avoid caffeine before floating for it may interfere with your ability to relax.

Will I float? I don’t normally float in water.
Yes. It is impossible not to float in the tank. 1000 pounds of Epsom salts dissolved in the water make a buoyant solution much denser than water alone. So no matter your weight or height, you will float on your back without effort. As you lay back, the water will reach the temples; leaving your eyes, nose and mouth fully exposed.

Can you fall asleep in the tank?
Yes. Many people safely fall asleep in the tank as a result of being so relaxed. Even those who say they never sleep on their backs in bed, do so very easily in the tank. People may think it is unsafe due to the fear of rolling over. If this were ever to happen, the salinity of the water would irritate the eyes and nose- immediately waking the floater.

Can two people float in one tank at the same time?
No. Floating is intended to be a private, individual experience.

Will I have Epsom Salt stuck in my ears?
No. Earplugs are provided to enhance your floating experience. We recommended rinsing your ears out with water after each session.

Is the salt dangerous to your eyes?
No, but it can be a little uncomfortable. Before entering the Chamber, make sure to dry your face off, push your hair back and keep your hands away from your eyes.

Is anyone unable to use the tank?
People with infectious diseases and those who are epileptic (not on controlling medication for the condition) should avoid using the tank.

Can I float if I’m menstruating?
Yes.  Just follow the same protocol you would for a swimming pool.

Can pregnant women float?
Yes. Pregnant women probably get more relief from floating than most people. The extra weight carried by the mother-to-be can be very stressful due to the forces of gravity. Floating eliminates the negative effects of gravity, which causes joint pain, inflammation and stress on the organs as well as the unborn baby.

Pregnant women have also reported a reduction of erratic movements of the baby inside the womb. This is due to a phenomenon call “mirror effect.” The baby is safe and secure inside the womb and the mother shares a similar experience in the isolation tank. Women report a stronger connection with their baby when exposed to this environment.

Is there an age limit to float?
If you are under 18 years old, you will need your parent’s permission. If you are over 100, you will need your child’s permission.
