The tanks & rooms here
No lid to close over you — the answer for anyone who feels boxed in. Open pools, open rooms, or pods whose door stays open.
The classic enclosed capsule with a hinged lid. Deepest sensory deprivation; you lie down and pull the lid to.
The room itself is the vessel: no hatch, walk straight in. Great for claustrophobia and easier access.
Water & cleaning at East Coast Float Spa Princeton
Sanitation is the thing seasoned floaters care about most, and most directories never show it. Between every float, the salt water should be pumped through fine filtration and disinfected — salt alone is not enough. From East Coast Float Spa Princeton's own information: UV sterilization, ozone, hydrogen peroxide.

What floaters say
“Phoebe was very kind and helpful and the facility was incredibly clean and relaxing.”
“She showed us around and explained everything so we feel comfortable and had a relaxing experience.”
“The experience was made that much more positive, relaxing, and memorable because of Annie's incredible service, care, and attention.”
“I was able to shut off my wandering thoughts and the pain relief I felt immediately afterwards extended into the next day through my whole body.”
“It's also rare to have uninterrupted quiet time in this day and age, but floating gave me a chance to quiet my mind and be present for a bit.”
“The staff is very welcoming and friendly Andrew and Emily are super helpful with questions and suggestions!”
From the reviews
Upon first arriving to the Spa, I was greeted kindly by Phoebe. She gave me a tour of the Spa and I was informed on the practice of floating. My experience with floating was just as good! I felt very relaxed, and just let go of all my tension. My mind felt quiet and I allowed myself to be in the moment.
I love this place. It’s my zen. I start off with 20 minutes in the gravity chair (this is my future husband) so that I get nice and relaxed and prepped for my float. If you’re in the chair next to me you might hear yummy noises. Then I go float. I prefer a blue light with continuous music.
I am so happy I found this Floating Spa!! When I say Amazing! It simply is! Clean, organized and timely! The staff is very welcoming and friendly Andrew and Emily are super helpful with questions and suggestions! I leave this place brand new without a care in the world after my sessions!
What a nice treat! The facility was clean and beautiful. The attendant was friendly and explained everything clearly, assuring me that she would be there if I had any questions or concerns. The float itself was divine, I definitely dozed off a couple of times.
Your first float at East Coast Float Spa Princeton
Never floated before? Almost no one has their first time, and a good center expects it. Here's what to know. What it is: you float effortlessly in about ten inches of skin-temperature water saturated with around 1,000 lbs of Epsom salt — so dense you cannot sink. In the dark and quiet, with no light, sound, or gravity to react to, your nervous system downshifts. Before you come: don't shave or wax for a day beforehand (salt stings fresh cuts — they'll have barrier ointment if you nick yourself), skip caffeine, eat a light meal an hour or two before, and remove contacts. If you colored your hair recently, wait a few days. In the tank: shower first, put earplugs in before you get wet, and keep a fresh-water spray bottle within reach for salt in the eyes. You can leave the light or music on until you settle, then turn them off from inside. Hold your arms out for the first 20–30 seconds to stop bobbing, then let go. It takes a few tries — the first 20 minutes are usually your mind winding down. Arrive 10–15 minutes early to shower and get oriented.
