Frequently asked questions



  • I have booked a combination float and massage, which session goes first?
    • The deep state of relaxation reached during a floating session is perfect in combination with a massage. We recommend you to float after your massage, especially for first-time-floaters. In that way you start the floating session completely relaxed. However, each guest of Koan Float has his/her own preference, so please feel free to choose your own personal order.

  • What is the cancellation policy?
    • Cancellations made 24 hours prior to the scheduled appointment are free of charge. All other cancellations are subject to the cancellation fee (100%).


  • Can I float during my menstruation period?
    • No, we’re sorry. Floatingis not allowed during your menstruation period (and not advisable).

  • Can I float if I am pregnant?
    • Yes, although it is always sensible to check with your doctor first. The weightless environment of the tank is actually greatly benefical for expectant mothers and is experienced as very relaxing. Stress and stain on your back and abdominal muscles is alleviated during your float. The deep state of mental relaxation is also wonderful for both mother and child. If you experience a lot of nausea during your pregnancy or when in doubt, then please contact us before your float session.

  • Can I eat before a floatsession?
    • A light lunch or souper is advised, please do not arrive on an empty stomach before floating. However it’s not advised to eat a heavy meal before your session. Please note that the use of alcohol and/or drugs is strictly forbidden before your float and/or massage.

  • Can I drown if I fall asleep during floating?
    • No, this is not possible. Some people may fall asleep during floating, while becoming completely relaxed. This is a wonderful experience! The salt levels in the water ensures enough buoyancy, which makes it impossible to effortlessly turn around while floating.

  • Can I come with a friend and float at the same time?
    • Sure! Floating is a very unique experience and it is wonderful to share it with a friend. We have three floatrooms and we can schedule your floats simultaneously. However it is not possible to share the same tank.

  • How do I know it is hygienic? Is the water cleaned after each session?
    • An advanced system filters the water between each float session ensuring a totally clean, sterile environment. The water is cleaned using UV light filter, hydrogen peroxide and 500 kg’s of Epsom-salt. It is tested daily by ourselves on PH value, salt levels and temperature. Furthermore, it is tested monthly by an independent laboratory.

  • From what age are you allowed to float?
    • No, there is no age limit. We suggest however that a floatsession is not suitable for children under the age of 14. The experience is that they get easily bored during the session. You may accompany or supervise your young child. Please contact us before making a reservation to discuss the possibilities.

  • Do I have to wear a swimsuit?
    • No, you float within your own individual private room, so there is no need to wear a swimsuit or trunks. Each of our rooms has it’s own shower and changing facilities is for your exclusive use for the duration of your session. Everything is included in the price so you don’t need to worry about towels, a bathrobe, and hair/care products.

  • What should I bring?
    • Nothing at all! We provide everything such as towels, bathrobe, shampoo, shower gel, showercap, deodorant, hair-conditioner, a hairdryer and even a nice cup of tea afterwards in our lounge. We have a large selection of relaxing music. However, if you would prefer to listen to your own music you may bring a CD or your iPod. If you wear contact lenses, you’re advised to bring lense-box.

  • Is there anything else I should know?
    • Avoid shaving at least three hours before your float as freshly shaved skin may be irritated by the salty water and thereby detract from the experience. A light lunch or souper before your session is no problem (and is advised), however the use of alcohol/drugs is strictly forbidden.

  • I have a skin problem. Am I allowed to float?
    • When suffering lightly psoriasis only, you are allowed to float. With more severe scin complaints or when in doubt, please contact us or your doctor before making your reservation. It is always healthy for your skin, however the salty water may sting (in case of open wounds etc.).

  • What if I am claustrophobic?
    • The measurements of the floating tank are large (long 220cm, wide 180cm and the height is 155cm). The fact that your float tank is in a private room (meaning there is no need to close the lid of the tank) and that you’re in complete control of the light, the music and the intercom from the inside at all times, gives you the total control of your environment. In general all our clients experience the floatsession as very pleasant, even claustrofobic people.

  • What are the measurements of the floatation cabin?
    • The measurements from the inside of the floatation tank are very large: Long 220cm , wide 145cm and height 140cm.
