This award-winning design is the perfect comfort spa. The computer-drafted design recognizes that people are built different so each therapy seat is made to accommodate these differences. Matching the seat to your body type is the best way to ensure that you can comfortably enjoy all of the therapy your Arctic Spa can provide. In the Tundra, you'll find a seat that fits you perfectly whether you are small, medium or large! Its unique layout, overall size and large foot well can accommodate a crowd, and do so without sacrificing the comfort features found in every seat. And every Tundra comes with a backlit waterfall as standard!
