Q: I'm new to this, what do I need to bring for my float?

A: Nada. Since you float in the nude, there's no need for a swim suit. We provide earplugs, towels, shampoo/conditioner and body wash. We have a hair dryer in our bathroom. If you'd like to bring your own shower shoes, you're welcome to. Arrive 10 minutes early your first time so one of our guides can walk you through the process.


Q: What if I'm claustrophobic?

A: This is a common fear for first-time floaters. It's totally cool. Fear not! The feeling of floating is so freeing and relaxing that the apprehension of tight spaces goes away very quickly. If you feel like you're having a tough time, you can open the door of the tank and get out right away, no questions asked. If you want to float with the light on, or with music, that's okay too. It's your call. Ultimately, this may be the best tool out there for helping you overcome claustrophobia. It's inherently relaxing, and you're in control the whole time.

  • If you want to listen to music during your float, please bring your own 60 minute playlist (and a dongle, if you have the newer iphone).


Q: How long is the float session?

A: Your float is 1-hour long, but you should aim to arrive around 10-15 minutes beforehand so you can park, arrive, check in and shower before your float. You have 10-15 minutes to shower afterward as well, and there's no rush if you want to hang out and have some tea on the couch.


Q: How is the water cleaned?

A: We abide by the Washington State and King County Health Department codes. The float tanks are constantly tested and balanced to assure the highest level of cleanliness possible. Our water is cycled 4 times through an advanced filtering process between each float session., and these filters are fully effective to one micron, which is 100 times smaller than a human hair. Plus, the density of Epsom salt in the solution is so high that, much like the Dead Sea, bacteria and other nasties can't survive. On top of this, we maintain a safe level (100 ppm) of hydrogen peroxide, a powerful disinfectant. Water sanitation is extremely important to us, so we continually test and monitor it to make sure it is perfectly clean and safe, so you can relax knowing the environment is completely sterile.


Q: Do I need to do anything to prepare?

A: Refrain from drinking caffeine for a few hours before your float (caffeine is a stimulant, and can make you jittery during your session). If you can plan for it, don't shave or wax before your float. The salt water can irritate some folks' skin. Eating something light 90 minutes beforehand is also a good idea, since a grumbly tummy can be distracting during your float. 


Q: How long have people been doing this Sensory Deprivation thing?

A: Dr. John C. Lilly created the first Sensory Deprivation Tanks in late1950s and other folks have been improving upon the designs since then. Athletes, Meditators, & Creatives have been floating widely since the1960s. 


Q: I suffer from high levels of stress and pain, will this help?

A:  Very likely. We see people find relief from pain and stress every day. There are volumes of research supporting floatation therapy as an effective treatment for ailments such as chronic stress, fibromyalgia, chronic pain, MS, anxiety, severe back pain, insomnia and much more. Here are some resources:, Floating for PainFloating and MeditationFloating and Stress ReliefFloating and Back PainFloating and Increased Well-Beinga quick primer


Q: What will a float session do to my hair-dye job? 

A: Great question. We suggest that you wait at least 2-weeks after you dye your hair or until your shower water at home runs clear before floating. The salt can diminish your hair color if it was done recently. Fresh dye can also do a number on our float tanks/pods and towels. So, we thank you for waiting to float.  


Q: Do you do walk-ins?

A: Not often. We're typically booked up the day of, ESPECIALLY on the weekends. It's a good idea to call in to book, or check out the schedule below.


Q: How long have you been in business?

A: We opened Float Seattle in November of 2012 in Greenlake. Our Bellevue studio opened in July of 2015, and our newest location in Greenwood opened in July of 2019.


Q: Can I float with another person in the float tank/pod?

A: We allow only single-person floats. There are 4 float tanks in Greenlake, 3 pods + 1 cabin in Bellevue, and 6 spacious float “orbs” in Greenwood - so if you want to float with a group, give us a call and we'll take care of you! 206-673-5132

 Q: What if I get motion sickness easily?

A: If you tend to get motion sickness, you may want to take some over-the-counter medication prior to your float (i.e. non-drowsy Bonine or Dramamine).

Q: Can I float if I'm on my period?

A: Sure, just bring the proper accoutrements as if you were swimming at a public pool.

Q: What if I'm pregnant?

A: Floating is not only safe for pregnant women, but is highly encouraged! Float sessions not only provide you with stress relief and weightlessness, but coupled with the Epsom salt's anti-inflammatory properties, a float session can really ease the strain on a pregnant body. The quiet, stimulus-free environment is a beautiful opportunity to connect more closely with your baby as well. All that being said, we recommend that you consult your doctor before booking a session.

Q: What are the differences in your float tanks?

A: There are some small aesthetic differences in the tanks, but once you're inside the experience is all the same. That is to say dark, quiet, warm & floaty. Meet our tanks here.

Q: I've floated once (or a few times), how do I learn more and dive deeper?

A: Awesome! Floating is one of those rare things that gets better and better the more you do it. The mental and physical benefits compound, as you continue to find more depth from the experience. So keep floating!
