So how much does a float tank cost? Float tank prices vary widely depending on the size and the features of the float tank or pod you want to buy. Expect to spend anywhere from $12,000 to $40,000 to buy each commercial-grade float tank needed in your spa.
The Floatation Tank is a light-proof, sound-insulated capsule which contains a shallow 30 cm pool of 25% saturated Epsom Salts solution â five times denser and more buoyant than sea water. Lying back, you float effortlessly on the surface with all parts of your body firmly supported.
