Hot Tub Shells

The hot tub shell is one of the most important parts to consider when purchasing a hot tub. Other elements, such as pumps or heaters, are fairly easy to repair or replace if something goes wrong. However, if the hot tub shell malfunctions, it is more than likely that the entire spa will have to be replaced.

There are two components that, when sandwiched together, make up the hot tub shell: the shell surface and its understructure. These two components provide completely different benefits to the hot tub shell. The shell surface determines the aesthetic look and feel of the hot tub shell, as well as its resistance against UV rays, chemical sanitizers, and customer abuse. Other factors include stain resistance and ease of cleaning. The shell understructure provides the structural integrity to the hot tub shell, determining both the spa's longevity and its ability to support the weight of the water. The shell understructure also decides the hot tub shell's resistance to deterioration such as delamination, bubbling, and cracking.
