A float tank is a purpose-built water system designed to let a person float with very little physical effort. The water contains a high concentration of Epsom salt, which increases buoyancy, while the enclosed or semi-enclosed environment is designed to reduce outside distraction.
Float tanks are also commonly called float pods, isolation tanks or sensory deprivation tanks. The terminology varies, but the basic principle is the same.
How does a float tank work?
The tank is filled with shallow water and a large quantity of dissolved Epsom salt. The dense solution supports the body at the surface, so the user does not need to actively swim or tread water.
The system also manages water temperature and filtration. More advanced home and commercial systems can include integrated controls, lighting, sanitation and remote monitoring, depending on the model.
Why is Epsom salt used?
Epsom salt increases the density of the water, which creates the buoyancy needed for effortless floating. It also forms a major part of the initial setup requirement for a float tank, so buyers should include salt in their ownership budget.
Float tank, float pod and sensory deprivation tank: is there a difference?
These terms are often used interchangeably. “Float tank” is the broad category. “Float pod” usually describes a pod-shaped design, while “sensory deprivation tank” is a common search term for the same general experience.
For buyers, the more important differences are between individual models: interior size, construction, controls, water-care system, intended use and installation requirements.
Can you install a float tank at home?
Yes, some float systems are designed specifically for residential use. The practical question is whether the room and property can support the chosen system.
Before ordering a home float tank, check:
- Product footprint and service clearance
- Access from the delivery point to the room
- Electrical requirements
- Water and drainage requirements
- Flooring and room finish
- Ventilation and humidity management

What is a commercial float tank?
A commercial float tank is selected for repeated use in a business environment such as a float center, spa, hotel, recovery facility or wellness space. Commercial buyers usually need to consider more than the guest experience. Room planning, cleaning workflow, maintenance access, operating consistency and delivery logistics all matter.
DreamPod commercial options on SimWellness include the Sport, V2 and Vmax. See the commercial float tanks and float pods collection for the current range.
How much does a float tank cost?
Prices vary significantly between home and commercial systems. The equipment price is only part of the project cost, because freight, site preparation, utilities, salt and installation can also contribute.

Which DreamPod is right for you?
There is no single best model for every buyer. A residential customer with limited space is solving a different problem from a commercial operator building a multi-room float facility.
