Sensory deprivation promotes neuroplasticity — the brain's ability to reorganize and form new neural connections. By removing external stimulation and the constant demands of gravity, the nervous system can shift from a chronic stress response back toward its native state of calm, relaxed clarity. Peer-reviewed studies have linked flotation-REST to enhanced problem-solving, improved learning capacity, and the induction of altered states of consciousness associated with deep meditation.

Yes. The density of the Epsom salt solution means you float effortlessly on your back with your eyes, nose, and mouth fully above the waterline — regardless of your size or weight. Many floaters drift in and out of a hypnagogic "twilight state" that sits between waking and sleeping, which research associates with heightened creativity and insight.

Sessions are calibrated to last 60–90 minutes, a duration precision-tuned to achieve optimal neurological benefits. This window allows the mind to move past habitual thought patterns and access progressively deeper states of relaxation and cognitive clarity.

Research and clinical data have linked flotation therapy to a wide range of benefits, including:

• Reduced stress, anxiety, and PTSD symptoms

• Accelerated physical recovery and lower blood lactate

• Enhanced creativity — studies show around a 33% increase after flotation sessions

• Improved sleep patterns and lower blood pressure

• Increased endorphin and dopamine levels with reduced cortisol production

• Accelerated learning and heightened focus

• Support for addiction recovery and mindfulness practice

Float Lab chambers measure 5 ft wide × 8 ft long × 7 ft high, with a large easy-access door of 3 ft × 5 ft. Each chamber contains approximately 12 inches of solution loaded with over 1,000 lbs of USP-grade Epsom salt. Chambers are available in both 50 Hz and 60 Hz electrical configurations and can be customized in an array of colors and materials to suit any facility.

Float Lab's founder, Crash Hoefler, served as a member of the NSF joint committee and chairperson of their Sensory Deprivation Task Group, as well as a member of the CDC's Council for the Model Aquatic Health Code (CMAHC). Float Lab has worked with public health authorities worldwide — including the Canadian CDC and Ministry of Health — to define and advance safety and hygiene standards for the flotation industry.

Float Lab's patented disinfection process is certified to produce a minimum 3-log kill (99.9%) of all microorganisms per cleaning cycle — without using any toxic halogen chemicals. The multistage filtration system finalizes at 1 micron, making the solution safe for sensitive skin and other sensory needs. A full disinfection cycle runs between every session.

NSF 50 is a public-health standard for water circulation and disinfection in commercial aquatic systems, administered by NSF International. UL 1795 is an Underwriters Laboratory electrical safety listing. Float Lab endured the longest testing process in NSF's 75+ year history — nearly three years — to achieve both certifications, confirming that every chamber meets the most rigorous safety and hygiene benchmarks in the industry.

Float Lab chambers are the world's only isolation flotation system to hold both NSF 50 and UL 1795 certifications for commercial use. They are constructed from stainless steel, feature a patented non-halogen disinfection system using three-stage filtration, ozone and UV light for the purest float possible.

Sensory deprivation — also known as floatation therapy or isolation therapy — is the practice of floating in a dense salt solution inside a light-free, sound-resistant chamber. The solution eliminates the brain's need to navigate gravity, while the absence of external stimulation allows the mind to redirect its focus inward. The result is deep relaxation, heightened self-awareness, and measurable reductions in stress and tension.
