Why Strong Spas?
Strong Spas doesn't just build hot tubs — they engineer wellness systems. Every component is designed for longevity, efficiency, and an unmatched ownership experience.
Industry-Leading Warranty
Strong Spas backs their products with the industry's most comprehensive warranty — Lifetime on shells and structural components, 10 years on all other components, 5 years on plumbing and electrical. No other manufacturer comes close.
DURA-SHIELD® HardCover
The patented DURA-SHIELD® HardCover replaces traditional foam covers with a rigid, insulating hard cover. On the Iconic® Series it's fully automated — no lifting, no struggling. It locks tight, insulates better, and lasts decades longer than foam.
Strong-Bond® Shell Technology
Strong-Bond® shells are engineered with a proprietary multi-layer composite construction — dramatically stronger and more impact-resistant than standard acrylic shells. They resist cracking, fading, and delamination for the lifetime of the spa.
DURA-BASE® Foundation
Every Strong Spa sits on the DURA-BASE® — a rot-proof, pest-proof, high-density polymer base that replaces wood framing. It never warps, never rots, and provides a stable, insulating foundation that protects the spa's underside for life.
UV/O3 Dual Sanitation
The built-in UV and ozone dual sanitation system destroys bacteria, viruses, and contaminants at the molecular level — reducing chemical usage by up to 50%. Cleaner water, less maintenance, and a healthier soak every time.
STRONGTOUCH™ Touchscreen
The full-color capacitive STRONGTOUCH™ touchscreen puts complete spa control at your fingertips — water temperature, jet speed, lighting, and optional WIFI connectivity for remote management from your phone.
Made in the USA
Designed and manufactured in Pennsylvania, USA. Strong Spas uses industrial-grade galvanized steel frames, American-sourced materials, and rigorous quality control — every spa is built to last decades, not years.
CEC Energy Certified
Strong Spas passed the rigorous California Energy Commission (CEC) efficiency test — one of the toughest energy standards in the world. Lower operating costs, better insulation, and a spa that pays for itself over time.
