How to buy a hot tub
Decide where to put your hot tub.
People install 90 percent of all hot tubs outside on a patio or deck. Of the 10 percent installed inside a home, most go in the master suite, an enclosed sun room or a finished basement.
Measure the hot tub area to ensure a comfortable fit. Be sure to allow enough room for getting in and out of the tub.
