Spa Pool Shells

Spa Pool Shells

The deepest, most immersive spa pool soak

At Hot Spring we use exclusive manufacturing techniques to create unrivalled spa pool shells. We can make our shells 2-3x thicker and our seats and footwells wider and deeper than any other brand on the market, to create the most comfortable soak.

Closed cell acrylic: an exclusive Hot Spring innovation

Where other brands use porous open cell acrylic for their shells, we use closed cell acrylic. It’s more difficult and expensive to make, but the investment is worth it. It doesn’t stain or retain bacteria, viruses, oils and body fats, and frequently last 20+ years, even when exposed to the elements.

“Do yourself a favor and get one. We have just bought a new Sovereign Hot Spring Spa on Saturday, and are very excited about this. The spa we have at the moment is also a Sovereign which we bought from Hot Spring Spas 24 years ago. I consider 24 years for a spa to last shows how great the quality of these spas is, and to me it shows how much more superior Hot Spring Spas are to other brands.”

Our spa pool shells are 2-3x thicker than all others on the market. This makes them ultra-hard wearing, and the non-porous, closed cell acrylic is simple to maintain – just give it an occasional wipe to keep it looking like new!

Our manufacturing methods allow us to form the shell into shapes that other brands simply can’t, including deeper, most comfortable seats. You just won’t find a more ergonomic soaking experience than the one in a Hot Spring.
