Water & cleaning at 307 Healing Waters

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 307 Healing Waters's own information: UV sterilization, ozone, hydrogen peroxide.

The float-industry standard is turning the entire volume of water over at least three times between sessions through a 1–10 micron filter, paired with UV and/or hydrogen peroxide or ozone. If a center doesn't publish its process, it's fair to ask.

From the reviews

What a beautiful, inviting space! I was greeted with a tour and given simple instructions for a wonderful experience. The detox program on the infrared sauna was excellent. The float tank is super cool! It really gave that sense of floating through space.

I love 307 Healing Waters. The floats are amazing. The water is the perfect temperature to be comfortable. You can have music and a soft light if you like or complete silence and dark. Very clean and inviting. I would strongly recommend this place for anyone who hasn't tried a sensory deprivation tank before.

★★★★★ — Kathie, Oct 2020

I went for my first float over the weekend and it was absolutely incredible! I am legally blind and Tricia was incredibly helpful and showed me where everything was and how to work everything. She was very caring and considerate! She seemed happy to be there and never made me feel rushed.

★★★★★ — Kendall, Mar 2021

I was in town for Christmas and wanted to try out the float for the first time. 307 is a very clean place with state of the art equipment. The owner is amazing and very informative. I will be back before I leave town and try the light table. Thank you!

Your first float at 307 Healing Waters

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.

Floating isn't for everyone: skip it with epilepsy, kidney disease, uncontrolled heart conditions, open wounds, a contagious condition, or in the first trimester of pregnancy without your doctor's OK. If in doubt, ask the center and check with a physician — this is general information, not medical advice.
