Are Soft Tubs Inflatable and What Are They Made Of

Soft tubs are not inflatable. They are called "soft" tubs because they use high-grade foam for their construction. The foam used has a soft texture, but has enough structural integrity to support the shape and demands of a hot tub. Aside from being soft, the foam used also has good insulation properties so heat is retained within the tub. The foam also makes the soft tub lightweight and easy to transport. Vinyl is also used on the tub to protect it from potentially harmful elements. This allows you to use your soft tubs in the outdoors, which also contributes to the portability of soft tubs.
