Custom Built Hot Tubs and Spas

Design your own custom spa by first selecting its hot tub jets.

Other spa manufacturers may say "custom built" but we mean it! Thermo-Spas are the only hot tubs that give buyers so many options, that each custom hot tub's cost matches the buyer's budget.

First, you choose from 10 to 160 jets.
While the average number of hot tub jets in other hot tub brands is only 20, your Thermo-Spas hot tub could have as many as 160 or as few as 10! Every one of our spa models has a basic, advanced and all-inclusive version.

Next, you tailor by color and feature.
We offer a wide variety of marble and granite shell colors, plus your choice of cabinet materials and colors including a range of Thermo-Board exteriors and Western Red Cedar. Some of our hot tubs offer grab bars that light, built-in ice buckets, and pillows with neck massaging jets. Or spas that let you pick the depth of a special seating area, to ensure you get a water therapy seat that's right for you.

Now add the options that make your spa unique.
All of Thermo-Spas' hot tubs offer the ability to add an array of elegant spa accessories such as planters, cabinets and hot tub steps that help turn every spa into a beautiful, at-home retreat. We also offer you a choice of water sanitizing systems, hot tub heaters, control panels, lighting designs, hot tub stereo systems and more.
