Owning a hot tub is a luxurious option for todays homeowners. The first decision that needs to be made is whether to get a self-contained spa or hot tub, or whether to get one that is not self-contained.
A self-contained hot tub is portable and can be used where desired. If you wish to make it seem a bit more built in, you can build a deck partially around it. One advantage to a portable hot tub is that all the plumbing, filtering, heating, and electrical components are enclosed in the cabinet of the spa. A non-portable hot tub is usually built in as part of an inground pool area, and has its own advantages.
