The Summit Series

Luxury Meets Versatility

At Strong Spas of Michigan, the Summit Series brings together sleek modern design, thoughtful engineering, and unmatched convenience. Perfect for those who want both style and substance, the Summit line offers advanced hydrotherapy features and an elegant look that fits beautifully in any backyard. Built with ULTRASTRONG® cover lift technology and our patented DURA-SHIELD® HardCover, the Summit Series eliminates the hassle of traditional spa covers, making your relaxation experience effortless from start to finish.

Strength From the Ground Up

Every Summit hot tub is engineered with our dual-walled DURA-BASE® foundation supported by a galvanized steel frame — the thickest and strongest base in the industry. Designed to resist pests, moisture, and wear, it also provides even load distribution and acts as a thermal barrier, reducing energy costs. And with minimal site preparation required, installation is simple and stress-free.

Effortless Protection With DURA-SHIELD®

Say goodbye to heavy, waterlogged spa covers. The DURA-SHIELD® HardCover, anchored with stainless steel hardware and supported by the ULTRASTRONG® lifter system, makes it easy to open and close your hot tub with minimal effort. This patented design is built to last and guaranteed to protect your investment for years to come.

STRONG-BOND® Spa Shells

Durability meets design in our triple-layer STRONG-BOND® spa shells. These thick, triple-layered shells resist sagging, prevent delamination, and eliminate air pocket issues. With an eco-friendly manufacturing process that avoids harmful fiberglass VOCs, the Summit Series spa shells not only look beautiful but are also better for the environment.

Pure Water With UV/O3 Sanitation

Enjoy naturally clean water without the heavy reliance on chemicals. The UV/O3 sanitation system combines ozone and UV light to deliver a clean that’s up to one million times faster than traditional oxidizers — giving you safer, clearer water while eliminating chemical by-products.

Smart Options for Modern Living

The Summit Series doesn’t stop at the essentials. With optional Wi-Fi app connectivity, you can adjust your spa settings remotely, ensuring it’s ready whenever you are. For the ultimate experience, add the premium sound quad transducer system for rich, immersive audio while you soak.
