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.
A walk-in enclosure with full standing height — for taller floaters and anyone who wants privacy without a low lid.
The room itself is the vessel: no hatch, walk straight in. Great for claustrophobia and easier access.
A room-sized open pool of salt water. Zero enclosure, easiest for two, most spacious of all.
Water & cleaning at Radiance Day Spa
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 Radiance Day Spa's own information: UV sterilization.

What floaters say
“The environment is relaxing and clean, soft background music, spa scents that aren’t overwhelming, and a cold glass of water for after.”
“When I got up off the table it occurred to me that I didn’t wince because of back pain.”
“He adjusted the sheet carefully and ensured I was always properly covered before transitioning areas, which made me feel completely comfortable and at ease.”
From the reviews
What an amazing place, friendly and happy! A lot of positive and relaxing vibes. I am more than happy! I love the place, employees, lotions, rocks, ambience. It just syncs in beautifully.
Today was a session with Blake to deal with neck and back pain. He was thorough, identified the issues, and worked the knots out. I felt so much better that I have already booked my next session with him. Blake was understanding, competent, and caring. I highly recommend him and the entire Radiance experience.
I have been to Radiance a handful of times now (mostly booked by my significant other) and it has been absolutely amazing each time! The environment and staff are so welcoming and calming. I have experienced other massages elsewhere and have never enjoyed it as much as my experiences at Radiance!
My back was sore and I thought it was a pinched nerve. Aimee found a knot that was causing the discomfort and the pain in my back disappeared. Radiance Day Spa is a first class establishment with top shelf staff.
Your first float at Radiance Day Spa
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.
