Portable whirlpools include small spas or inflatable spas. Also, spas that attach to a tub are available, such as a mat-style bath spas or a portable spa motor.
Traditional small spas and inflatable spas are either inflatable or made of acrylic. They typically hold two to four people and can plug into a standard 120-volt outlet. The spas come with pump and heater and have multiple jets. The spas fold for easy portability.
There are two main types of bath spas available. Mat-style spas are designed for sitting on or wrapping around the body and creating bubbles. Jet-style spas are essentially portable whirlpool motors. The motor is attached to the side of a tub and pumps heated air bubbles, much like a traditional spa.
