Custom Float Room

Float rooms are terrific options for people who might be uncomfortable in a closed pod or tank. Individuals taller than 6′ 2″ are easily accommodated with the larger tank. It’s even possible for two people to float at the same time.

Royal Spa open float tanks are designed for use in spas, float centers, and residential settings. They serve as the basis for creating your own custom float room.

The tub and equipment are made at our manufacturing facility in Indianapolis, Indiana where we’ve been in business for almost 40 years. Our first float tank was produced in early 2012.

There are two sizes available (drawings below). The smaller size model allows for easier placement in a home. Both open tanks are 24″ tall. A 14″ step-over access provides a seating or standing area on which you can dry off before exiting.

Float Tank Features

Pump and Circulation
Our energy efficient pump is just the right size to turn over the solution without creating other problems. An unnecessarily large pump forces to much salt in the air. This is especially bad for HVAC systems, electronic components, and computers. Worst of all it drives away customers because of the negative impact on air quality.

The pump is very quiet. You can have the pump running in one room and someone floating in the room beside it at the same time without disturbing their float.

Our pump will not overheat the solution. A pump motor that is too big moves the solution to quickly, creating unnecessary friction. This causes the solution to overheat. It can take hours to get the temperature back down to an appropriate level.

Purification and Filtration
Save time and money with our approach to filtration. We use a simple and inexpensive filter available at any pool supply store in the U.S.

Placement of the filter inside the tank helps prevent spillage of the solution on the surrounding floor. It also protects the pump motor and electrical components. Trust us. You’ll come to greatly appreciate that design feature.

Tanks are equipped with dual skimmers. This insures the surface integrity of the solution. The skimmer basket is located inside the tank, which is a requirement of many local municipalities.

Ozone and UV purification insures bacteria and viruses are eliminated from the solution, tank surfaces, and air.

Control System
We offer a computer controlled system for businesses who want to control multiple tanks. This allows central control of the tanks for starting and stopping the circulation process, lighting, and music. Alternatively, controls can be customized to be placed in room or the tank interior, if a central computer control is not needed.

Heating System
A 3000 watt flow-through titanium heating system creates approximately 10,000 BTU’s. This is needed to insure the salt can melt in a reasonable amount of time.

Under the tank is a waterbed style heating system which operates during a float. These two 500 BTU elements help replace heat that is loss while a person is in the tank.

The tank has 3 lighting options: 24 LEDs, 9 LEDs, or a single blue LED, which is what we recommend. Multi-colored options are available.

Unlike our competitors who use a polyester based resin we use a specialized resin formulated for chemical storage tanks. Magnesium sulfate solution is particularly destructive. A regular polyester resin will blister over time from contact with the solution.

All of our models have a 3.5mm input jack. Bluetooth is optional. (The pairing process can be difficult for users in a multiple tank setting). Commercial models also have a 2-way intercom system.

Float Tank FAQs

The solution itself would take over 19 years to degrade. You can’t “break” the solution. Theoretically, you could go for years without changing it. It’s possible you could have a situation where certain minerals have gotten in to the solution, creating a problem you can’t solve chemically. You might also decide to drain the tank to do some cleaning. In that case, the solution could be stored and returned to the tank once you’ve finished cleaning. Even in the case of a “biological event” you could remove the debris and let the system do its job. There would not be a need to change the solution.

An empty tank weighs approximately 700lbs (318kg). When filled with solution the tank weighs approximately 2600 lbs (1180kg).

The pod style float tank can accommodate people up to 6’9 (198cm)  An open float tank is also available. This is a good option for larger people and for those who might feel claustrophobic in a pod.

180 gallons of magnesium sulfate solution

Filters used on our tanks cost less than $20 and are available at most any pool supply store or online. A typical competitor’s filter could be over $200. Remember – you can clean and reuse filters.

The purification process cycles the entire solution 4x per half hour. It operates when the tank is out of float mode.
