Rather skip the table?
Ten questions, checked against all 390 hot tubs. You get the three that fit, with the best-built one first.
Common questions
What is the best hot tub brand?
On our eight build checks, read from each maker's manuals, warranties and spec sheets, Master Spas scores highest (7.5 of 8), then Cal Spas (6) and Marquis (6). The best tub for you also depends on size, seats, power and price, which the quiz sorts out.
Which hot tub brand has the best warranty?
Artesian Spas, Nordic Hot Tubs and Dimension One Spas cover the shell for life on their top series. Equipment and labor terms are shorter for every brand, so compare those too.
Which hot tub brands are made in the USA?
Master Spas, Cal Spas, Marquis, American Whirlpool, Artesian Spas, Nordic Hot Tubs, PDC Spas, Vita Spa and Bullfrog Spas name a US plant that builds their hot tubs. Some others build in the US and abroad, or don't say which plant built a given model.
What should I compare between hot tubs?
How it's built (the shell, plumbing, jets and parts), the warranty on the shell, equipment and labor, the size and seats against your space, the electrical it needs, what it costs to keep hot, and the price. The table above lines up the first four by brand.
Is there an independent hot tub comparison site?
HotTubFinder.com compares every brand on the same published facts and links each figure to its source. No manufacturer pays us.
