When you arrive at Copenhagen Float our receptionist will be there to welcome you. We will guide you step-by-step through your treatment in order for you to have the best experience.

Your float begins with a tour of your float space including the shower, tank and how to prepare for your float. 

You will start by inserting silicone ear plugs, then proceed to take a shower – washing your hair and body throughly. Once you are sqeaky clean, you are ready to step into the tank and lie down on your back – if you aren’t comfortable you can try using the float halo for extra neck support. You are in complete control of the light and decide when to turn it off when you are ready.

You will feel how the saline water keeps you floating effortlessly – the water is 30 cm deep and filled with 550 kg of Epsom salt. 

During the first 10 minutes of your float we will play calm, ambient music to ease you into the experience. When your session is coming to an end, this same music will gently remind you, that it is time to come back to Earth and get out of the tank. Take a shower, get dressed and come out to the lounge. 

Your float master will serve snacks, tea and water. You are also very welcome to use our groom room where you will find a hairdryer, brushes, and natural skin care products.

If you are using contact lenses, it is a good idea to bring a case for them as it is not possible to wear them in the tank due to the saline environment.

Otherwise we will provide you with all the things you need; towels, ear plugs, shampoo, conditioner, lotion, make-up remover etc.

You do not need to bring a bathing suit – we recommend you float naked. If you feel more comfortable floating in your bathing suit, you are welcome to bring it with you. 

It is a good idea to avoid caffeine before your float – this will help you to relax more easily.

Avoid waxing or shaving your face and body, since the salty water may irritate the skin when freshly waxed or shaved.

Eat a light meal or snack about an hour before your float so that you don’t get hungry during your session.

  • Have shaved or waxed within 24 hours
  • Have an infectious disease
  • Have experienced diarrhea within the past week
  • Have gotten a new tattoo within the past 4 weeks
  • Have had chemotherapy within the past two months
  • Have a kidney decease
  • Have very low blood pressure
  • Have sunburn
  • Dyed your hair within the past two weeks
  • Are in your first trimester of pregnancy and feel very nauseous
  • Suffer from epilepsy
  • Have an open wound or severe eczema

We have several tanks, which are all spacious (big enough to stretch out fully).
If you fear that you might feel claustrophobic, you could benefit from upgrading to our float room which can easily fit two people and has high ceilings. 

Most people with claustrophobia report feeling completely at ease once they see the size of the tank in real life, and are able to relax fully during their float. No matter which tank you choose, the doors are never locked and you are in control of turning on and off the lights.

After every float the water is rinsed for about 20 minutes. It is rinsed through an ultra fine particle filter – 1 micron – and radiated through a UV-C chamber. Every night before we close, we dose the water with hydrogenperoxide in order to maintain the highest levels of hygiene possible. It is not possible for any kind of bacteria or virus to survive in the float tank environment. Shelley will take you through the whole process here.

It is perfectly normal to fall asleep in a floating tank. The worst thing that could happen is that you get a bit of salt water in your eyes, which you can rinse off with the spray bottle provided inside the tanks.

It is not possible for your head to float underwater at any time due to the high salt concentration in the water.

In fact, research shows that sleeping in a float tank is more soothing than sleeping in a normal bed. Among other things, it can benefit people who suffer from sleep deprivation or generally just wants to improve their sleeping patterns.

Yes, if you would like to float for more than 60 min. just write to us on and we will make it happen.

Only in our custom-built 2-person float room. We do not allow more than 1 person in the Spirit tank and i-sopod tank at the same time. 

You are in total control of getting in and out of the tank. If you feel the need to step out before the end of your treatment, you are of course welcome to do so.

We recommend using ear plugs. It prevents the salt from settling in your ear canal and helps you to block out any quiet noises during your float (which helps you to turn the focus inwards on yourself!). 

If an ear plug falls out during your float, or if you simply prefer to float without them, it’s not dangerous at all, you just have to ensure that you rinse your ears thoroughly after the float. Otherwise the salt will crystallize over the next day. 

If you are suffering from the condition we call “salty ears” please read this blog post about how to get rid of the salt. 

Contact lenses are totally unnecessary while floating, because you won’t need to see a thing inside the deprivation tank.

We recommend that you remove your contact lenses before your float and store them in a case. 

If you are in the unfortunate situation where you get salt water in your eyes, it will be more difficult to rinse them with contact lenses in. 

Floating is perfectly safe for pregnant women. In fact, it is really quite wonderful to be weightless after carrying all that extra weight. It releases muscle tension, helps with circulation and reduces inflammation.

If you are in your first trimester and suffering from nausea, you may not wish to lie in a float tank for 1 hour. If you feel fine, then you are more than welcome to float. 

For some women in their 3rd trimester, it is not comfortable to lie on their back. This feeling is reduced in the float tank as you don’t feel the effects of gravity quite as much. If you are approaching your due date, we do not recommend floating as you might find it difficult to get in and out of the tank safely, and there is a small risk that you might go into labour/waters break during your float!

We recommend you wait until at least 4 weeks after getting a tattoo. It can be painful to float if your tattoo hasn’t healed and the saline water can have a bleaching effect on the ink.

No, you will have to wait for at least two weeks. If there is no residual color when you shower, you can float after having your hair dyed. 

If you have difficulty walking or lifting your legs a little high, it is a good idea to bring someone who can assist you when getting in and out of our tanks, as well as walking down the stairs to our studio, which is located in a basement with approx. 7 steps down.
