Float STL is a dedicated float therapy and wellness studio located in Brentwood, Missouri — a quiet residential and commercial suburb approximately 10 miles west of downtown St. Louis. The studio occupies a purpose-built space centered on sensory deprivation float tanks: large enclosed pods filled with roughly 10 inches of water saturated with approximately 1,000 pounds of pharmaceutical-grade Epsom salt per tank. The salt concentration creates enough buoyancy to support the body effortlessly at the water's surface, eliminating the sensory inputs of light, sound, and physical pressure and allowing the nervous system to enter a state of deep rest difficult to replicate through conventional relaxation methods. The flagship service is the standard 60-minute float session, priced at approximately $65, during which clients enter a private pod, extinguish any remaining light, and lie in silence as the salt water supports their body without effort. A 90-minute float extends the session for guests seeking deeper relief from chronic tension, athletic recovery, or anxiety management, and is particularly recommended for first-time floaters who may need the first 20 to 30 minutes to settle fully into the environment. Light therapy options can be added to the float experience through colored LED panels within the tank, introducing chromotherapy alongside the deprivation protocol for guests who prefer some gentle visual stimulus. Beyond floating, Float STL offers infrared sauna access at approximately $30 per session — a modality valued for raising core body temperature, promoting circulation, and supporting lymphatic function — and massage therapy services for guests seeking hands-on treatment to complement their float. The facility is designed for minimal visual and auditory stimulation throughout: walls are soft-toned, lighting is low across all common areas, and the intake process is calm and brief. Staff provide a full orientation for first-time floaters, covering what to expect during the session, how to enter and exit the pod, and how to manage the initial adjustment period. Ear plugs and petroleum jelly for covering small cuts or abrasions are provided at no charge. Clients shower before and after using on-site shower rooms, as the salt residue requires thorough rinsing. Float STL serves St. Louis-area residents seeking stress relief, sleep improvement, and athletic recovery, and is also used by meditators, artists, and those managing conditions such as fibromyalgia and generalized anxiety.

Tips for visiting
- Avoid caffeine for two to three hours before the float — it makes settling into the quiet environment noticeably easier.
- Do not shave on the day of a float; the Epsom salt water irritates freshly shaved skin.
- A 90-minute session is recommended for first-timers, allowing time for the initial adjustment period before deep relaxation sets in.
- Use the provided ear plugs — they prevent salt water from entering the ear canal during the float.
- Pair the infrared sauna with a float session for a deeper recovery protocol: sauna first, then float.
- Online booking is the most reliable way to secure a specific time slot, especially on evenings and weekends.
Frequently asked questions
What is float therapy and how does it work?
Float therapy uses tanks filled with heavily salted water that supports the body effortlessly at the surface while light and sound are eliminated, allowing the nervous system to enter a deep rest state. Sessions at Float STL run 60 or 90 minutes.
Is prior experience required to use the float tanks?
No experience is needed. Staff provide a full orientation for first-time floaters, explaining what to expect, how to adjust the pod settings, and how to manage any initial discomfort with the quiet environment.
Are the float tanks private?
Yes. Each float tank or room is a private, individual enclosure used by one person at a time, with an attached private shower for pre- and post-float rinsing.
What should be avoided before a float session?
Avoid caffeine for two to three hours beforehand, avoid shaving on the day of the session, and do not float over open wounds or freshly dyed hair, as dye can leach into the salt water.
How is the water sanitized between sessions?
The high salt concentration is naturally inhospitable to most pathogens, and Float STL uses additional filtration and sanitation systems between sessions. Clients are required to shower before entering the tank.
