What is unique about Samadhi Tanks?

For over forty years Samadhi Tanks have been designed with optimal functionality and elegant simplicity in mind, focusing on creating the best possible float experience for the user. This means providing an environment with as few distractions as possible, a space of empty nothingness in which the floater is supported in entering the space of silence.

We place a great deal of attention on providing this simplicity.


In our quest to provide the floater with the ultimate experience, we stay true to John C. Lilly's vision of the tank as a place to escape sensory stimuli and be at peace with the Self. Though a beautiful soft blue light is available for those who may be fearful of the dark at first, with the light off the tank is completely dark and lightproof.

This is achieved by using a black interior, by our special lightproof tongue-in-groove interface at the door, and by having our filtration system hoses manufactured so that the light is prevented from entering the tank through the fittings.


Like absence of light, absence of sound is an important aspect of providing a completely distraction-free environment. Closing the door of the room and laying back so that the ears are underwater eliminates airborne sound in all tanks, but environmental vibrations traveling through the building structure and entering the bottom of the tank, go through the solution and arrive at your eardrums.

We have solved this problem by designing and producing Sound Isolators made of alternating layers of proprietary sound deadening materials. These are placed underneath the tank to block any structure-borne sound from reaching the floater and entering their experience.


Floaters ideal temperature varies. A tank that.s too warm for someone will seem stuffy to that person. By lowering the temperature 1/2° - 1° the air then seems fresh.

After using the tank for a while, the body can become quite sensitive to temperature variations. Since the solution that feels perfectly comfortable to one person can be too cold for the next, we have added a radiant heating feature in the ceiling of the tank.

With the single push of a button a floater can increase the temperature of their skin surface and be perfectly comfortable.


Water collecting under the ceiling of the tank is a problem for every tank, including even those with sloped roofs. Most people solve this by squeegeeing the top of the tank frequently, or by laying bubble wrap over the surface of the water in between floats.

We have devised a much simpler and less time-consuming solution to this problem by adding a feature that heats the top of the tank in order to prevent condensation from accumulating in the first place.

Timing Mechanism

After years of experimenting with different timing devices for timing floats and filtration periods, including state of the art programmable timers, we have learned that more traditional timers - used to control manufacturing processes - work best.

With these we know that the equipment will not become obsolete when the maker comes out with a new model, ensuring that parts are always replaceable rather than requiring that the whole system be replaced when one piece stops working. This significantly cuts costs and lowers frustration levels.

Ease of Transportation

A float tank is a significant chunk of material substance, and getting it into your location may not be possible. Most tanks will not go around a corner and fit through a door, so unless you plan to build a room around a tank and are positive you will never need to move it, another solution is needed.

As this video demonstrates, our tanks come as a series of lightweight flat panels that are easily fitted together.

At Samadhi, we design with the floater's experience and reliability of use in mind at every step. We've done this by solving the problems that are tough for every tank manufacturer - elimination of light, absence of sound and condensation, temperature and air quality control, and keeping things simple so that obsolete parts don't require the replacement of an entire system.

Four decades of tinkering and perfecting have led us to the model we now use and sell, and we think you will agree that it is the easiest to use and most efficient tank on the market. Acquiring a tank is a major purchase, but getting all of Samadhi's unique features at the lower end of the price spectrum is well worth it.
