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.
âEmergency floatation units can be installed on the main landing gear fairings and on the forward section of the fuselage.â âEach tank is fitted with a gravity fuelling point and there is a pressure refuelling point in the landing gear fairing on the starboard side.â
