★★★★★ Hundreds of 5-star reviews on Google.
This place gives you the chance to zero everything out. Removes the stresses from life. Great staff — always welcoming. You can't beat it.
Kristie was amazing — she explained everything perfectly and allowed me to ask questions until I was comfortable. It felt so luxurious.
Owner Mark and Kristie make Somerville shine. Careful explanations for first timers and athletes looking to expedite recovery. Highly recommend.
One float is great. A regular practice is something else entirely. Our membership is designed to make floating a sustainable part of your life — not a once-a-year treat.
We live in this community. These are some of the ways we're trying to give back.
Started when a customer donated her remaining floats before moving away. We add a float for every review, every new membership, and every donation — then give them away to those who need them most.
We're exploring float sessions designed for kids — calm, quiet, screen-free. Before moving forward we want to hear from parents. Take the survey and help us build this the right way.

Get in touchFloat therapy (also called sensory deprivation, flotation therapy, or REST therapy) involves floating in a tank filled with 10–12 inches of water and 1,100 lbs of Epsom salt. The salt makes you completely buoyant with zero effort. Tanks are soundproof and lightproof, removing all external stimulation and giving your nervous system a genuine rest. Sessions are 60 minutes. Benefits include deep stress relief, reduced anxiety, better sleep, pain relief, muscle recovery, and mental clarity.
Your first float is $50. Standard single floats are $75. The beginner 3-float pack is $150 — the best starting point if you want to actually feel the difference. Monthly memberships start at $65/month and include one float, additional floats at $59, 10% off cryotherapy, and the option to share the membership. There's also an unlimited annual membership for $2,499.
You get 80 minutes total in the room — 10 minutes to shower before, 60 minutes floating, and 10 minutes to shower after. Plan for about 90 minutes door to door on your first visit. There's no rushing: the next guest's session doesn't start for another 10 minutes after you leave.
Rarely. Our tanks are larger than most people expect — including The Depths, our XL tank. You're always in control: the door opens from inside, you can leave a light on, or float with the lid open if you prefer. Our staff walks every first-time floater through the setup before you go in. Most people who arrive nervous leave wondering why they worried.
Floating is widely used for stress relief, anxiety reduction, nervous system reset, chronic pain management, insomnia, athletic recovery, PTSD support, and burnout. The weightless, soundproof, lightproof environment removes external stimulation and lets the body and mind decompress deeply. Mark completed a 30-day float challenge and recorded a 69% reduction in hs-CRP (an inflammation marker), a 33% increase in HRV, and a 43% increase in restorative sleep.
Yes. We use the TruCryo Kaasen device — liquid CO₂, not nitrogen — for localized cryotherapy. Targeted Recovery Boost for pain and inflammation is $50 (first-time intro $20), Advanced Skin Recovery is $99, and Body Contouring is $199. Members get 10% off all cryotherapy sessions.
Yes. Nordic Freeze contrast therapy is a private suite with an infrared sauna with red light therapy, and a cold plunge that goes as low as 37°F. The suite fits up to two people.

Everybody should do the tank.
For athletes, I'm 120 percent all in on it.
The float tank provided a specific place for meditation.
It's nice to be able to go somewhere you can shut it all down.
Reds were redder, blues brighter, the taste of food more explosive.
When you can't see out, you start looking in.
You could get into a dream state, and different pictures come through.
Like being in the belly of a whale. It was really lovely.
A bizarrely delightful experience. Calm and peaceful, yet energized.
One of the most anxiety-reducing experiences I've ever had.
Systematic review of 63 studies and 1,838 participants: consistent benefits for pain, athletic performance, stress, mental well-being, and clinical anxiety.
Fifty people across the anxiety spectrum — GAD, PTSD, panic, social anxiety — showed a significant drop in anxiety after a single hour-long float, with mood gains lasting past 48 hours.
First fMRI study of floating. After a float, connectivity between the brain's body-sensing network and its default-mode network dropped — the researchers call it taking the body off the mind.
Read on PubMedEight studies, 401 chronic-pain patients: lower pain intensity and frequency, better pain tolerance, and substantially reduced anxiety and depression across most studies.
Sixty-five working professionals, twelve floats over seven weeks: stress, depression, anxiety, and worst pain fell; optimism and sleep quality rose. The control group didn't change.
Read the studyRandomized trial of six repeated floats in 75 anxious and depressed adults: feasible, well tolerated, and safe, with few negative effects.
Read on PubMedTrained athletes who floated for an hour after hard exercise slept better and recovered jump and sprint performance faster than passive rest.
Read the studyRandomized pilot in generalized anxiety disorder: twelve floats produced significant symptom reduction that held at six-month follow-up.
Read the studyThe first placebo-controlled trial in chronic pain found short-term relief but no lasting benefit after five floats — and the placebo group improved too.
In twenty highly trained athletes, a single float beat a nap on how people felt afterward, but a nap did more for acute heart-rate variability.
