WHY OUR SPAS.
Why Choose our Pre-Engineered Stainless Steel Spas?
While our fully custom vessels require design lead times, our pre-engineered stainless stell spas deliver the luxury, hygienic benefits, and structural durability of marine-grade stainless steel in standardized, pre-engineered footprints ready for immediate site integration.
Flexible Installation Methods
- Designed for ultimate architectural adaptability. Install your Home Collection spa as a freestanding above-ground unit with custom exterior cladding, or as a seamless drop-in recessed vessel integrated flush into stone patios or timber decking.
Commercial-Grade Mechanical Packs
- Every Home Collection spa comes paired with a pre-plumbed, factory-tested equipment vault featuring industry-leading Balboa® or Gecko® Wi-Fi topside digital controllers, high-flow dual-speed circulation pumps, and heavy-duty 5.5kW titanium electric heaters (240V / 50A).
Clear Comfort AOP Sanitation
- Say goodbye to harsh chemical odors and skin irritation. Integrated Clear Comfort™ Advanced Oxidation Process (AOP) technology destroys 99.9% of waterborne contaminants, reducing chlorine and bromine reliance by up to 80% to protect both your skin and the steel finish.
Extreme Alpine-Grade Thermal Barrier
- Encased in a full-depth, closed-cell spray foam insulation envelope and paired with an insulated locking hard cover, the Home Collection guarantees minimal standby heat loss during severe winter drops.

Q & A
Stainless Steel Spa Questions
Can't find your answer? Feel free to reach out and we will help you out!
How does the Pre-Engineered Spa differ from full custom Tesoro® spas?
The Home Collection uses standardized, pre-engineered shapes and sizes (6'x6' to 8'x12'), allowing for faster factory turnaround times and streamlined pricing while maintaining the exact same 316L marine-grade steel construction and 25-year structural warranty as our custom builds.
Can the pre-engineered spas be installed on rooftops or elevated decks?
Yes. Pre-engineered stainless steel spas weigh significantly less than concrete or stone-tiled spas, making them an excellent choice for elevated decks, terraces, and rooftops. Load specifications are available for your structural engineer.
Is the equipment vault built into the spa cabinet?
Yes. For freestanding models, the mechanical equipment (pumps, heater, controller, AOP system) is housed neatly within the insulated cabinet. For recessed drop-in installations, a compact external equipment vault can be positioned up to 25 feet away.
