The Ultralife Shell

It is a fact that the surface of a spa is the most stressed and abused part of any spa design. Dimension One is the only manufacturer to offer shells made out of Ultralife. Ultralife is the strongest shell material in the industry. How strong is it? So strong that we offer it with a lifetime warranty.

As a bonus, it's also slip-resistant., so you don't need to worry about having dangerous accidents when getting in and out of your spa.

Echo Switches

The most annoying thing about any hot tub is that you have to leave your seat in order to change any of the settings. Echo solves this problem; Dimension One's exclusive magnetic switches are built right inside the spa. Best of all, they are placed under the water line, so you don't even need to reach out of the water for them.
