The Aspen Spas Hub
The only 100% USA-made hot tub brand — bought, delivered, and serviced by Colorado's authorized Aspen dealer for over 50 years. Guides, comparisons, and honest advice.
Aspen Spas builds every hot tub and swim spa entirely in the United States — the only brand in the industry that can say that. Shells, cabinets, plumbing, and electronics are all American-made under one quality system, with full-foam insulation engineered for climates exactly like Colorado's.
Carefree Spas has sold and serviced Aspen Spas from our Littleton showroom since 1976 — over five decades of matching Colorado families with the right spa, delivering and installing throughout the Denver metro, and keeping every tub we sell running for the long haul. This hub gathers our best Aspen-specific advice: buying guides, water care, winter performance, and what USA-made really means for your wallet.
100% USA-Made
The only hot tub brand manufactured entirely in the United States. One quality system from shell to cabinet — and it shows in our service bay, where USA-built spas spend less time under repair.
Full-Foam Insulation
Aspen fills the cabinet with foam around the shell and plumbing — the best heat retention in a Colorado January and built-in freeze protection for those minus-10 Front Range nights.
BluWater Salt System
The saltwater option on the spas we sell runs on brominating salts — not chlorine. Softer water, gentler feel, less chemical handling. One test soak in our showroom and most buyers are done deciding.

Aspen Spas is the only 100% American-made hot tub brand — every shell, cabinet, and component is manufactured in the USA. Carefree Spas in Littleton, CO has been the authorized Aspen dealer for the Denver metro since 1976.
Where can I buy an Aspen Spa near Denver or Castle Rock?

Are Aspen Spas good for Colorado winters?
They're built for exactly that. Full-foam insulation locks in heat through sub-zero nights and protects plumbing from freeze-thaw damage, and paired with a high-performance cover like the THRML AIRCAP 1™, an Aspen holds temperature efficiently all winter. Winter soaking is what these spas are made for.
