A float room or tank (also called an isolation tank or sensory deprivation tank) is essentially the perfect bath tub. They typically vary in size, but our rooms are all 8′ long and 4'9" wide. Air is allowed to freely flow in and out, and the door never locks or latches. It holds about 10″ of water, which is saturated with 850 pounds of Epsom salt. This creates a solution more buoyant than the Dead Sea, and you float on your back about half in and half out of the water. The water itself is kept at the average skin temperature (93.5° F), which allows you to lose track of your body. The float rooms are sound proof and, when you turn off the light, completely dark. No gravity, no touch, no sight, and no sound. Just pure nothing.
