A working hot tub is a great way to relax. The hot water and the bubbles can remove stress and release the tension from sore muscles. The unit can also entertain friends and romantic interests. The owner of the hot tub knows that he needs to keep the unit in good repair. If something goes wrong with the unit, he may need to find a person who can repair the hot tub. If the repairman needs to find specialized parts, he may have to order the parts directly from the manufacturer.
The process of finding hot tub parts is not as easy as the process of finding car parts. The user cannot got a junkyard and find the part he needs. There is unlikely to be a need for anyone using this business model any time soon. When a person needs hot tub parts, he often has to go to a specialty manufacturer. If he does not go directly to the manufacturer, he may need to go to a store that offers the part.
The hot tub does not have a lot of moving parts, but the moving parts that it does have differentiates it from a passive pool or a bathtub.
