Engineering The Best Hot Tub

Engineering the Perfect Hot Tub

Every part of the Bullfrog Spa Foundation is precisely built and fits together the same way every time. The EnduraFrame™ supports (injection-molded Z-beams) create an exact connection between the base, shell, and EternaWood cabinet. All of these injection-molded components are stronger than a traditional wood materials, eliminate the human error involved in cutting and fitting wood parts, and they will last much longer than a metal or wood frame that can rust or rot.

Engineered to perform perfectly…

Quality, In What You See...
And What You Don’t

Quality drives every decision at Bullfrog Spas. Our design and engineering processes are second to none. It shows in what you see and what you don't. Components like the EnduraFrame™, are built with laser precision and assembled with care. Extra supports are even added in high-usage areas to strengthen overall spa integrity and to create an exact fit.


As a part of the design, the composite molded EnduraBase™ spa base has hand-holds for moving the spa, convenient electrical chase-ways for easier electrical set up, vents to keep out unwanted pests, and an easy-access external drain.

Built better because we care…
