Eco-Effect Technology

This technology is built into every hot tub to help save you money in electricity. From the floor to the top cover, every hot tub is thermally insulated with 2″ of rigid EPS insulation and lined with a reflective layer to further capture heat and prevent it from escaping. Each hot tub’s insulation rating is an R-20 value and our covers are rated with an R-18 value.


We take pride in using 100% recycled ABS to fabricate our flooring systems on all of our spas. We also recycle 100% of our wood, plastic and cardboard waste.

Ever-B-Efficient™ reflective insulation outperforms spray foam insulation.

Our Ever-B-Efficient™ double-sided foil rigid insulation panels provide an R-20 insulation value. This system harnesses all thermal gain from the pumps and heater inside the spa cabinet, while reflecting the colder outside air away from the spa cabinet – thus maintaining the spa shell and water heat. In addition, the removable exterior panels provide easy maintenance access. Side by side comparison tests show Ever-B-Efficient™ insulation system to be 12% more energy efficient than using spray expanding foam.

Our fully insulated floor system provides the foundation to lift the spa off the cold ground to further insulate and protect the spa from moisture, bugs and other pests.

Ever-B-Strong™ acrylic shells are unmatched and eco-friendly

Our acrylic shell system has 3 layers of strength support plus expanded steel support in heavy traffic areas for the strongest shell system in the industry. Plus, our Ever-B-Green™ Eco Spray strengthing process is environmentally friendly and emits no or zero V.O.C.’s (volatile organic compounds) – unlike fiberglass resin shells that emit toxic V.O.C.’s into the air and may have adverse health effects.

Our PVC pillar supports won’t rot, mold, rust or let you down.

Birch Bay Hot Tubs™ uses a PVC pillar support system that will not rot, mold, rust or otherwise breakdown like other manufacturers that use wooden or steel supports. Many other manufacturers fill the entire skirt interior with low-density foam that can deteriorate and attract unwanted rodents to its warm and moist environment. Our PVC pillar support system, combined with the Ever-B-Efficient™ insulation panels and Ever-B-Sturdy™ floor, will give you the structural support unmatched by any other.

Ever-B-Sturdy™ floor system insulates and protect from the elements

Our weather-resitant, fully insulated floor system provides the foundation to lift the spa off the colf ground to further insulate and protect the spa from moisture, bugs and other pests. Our environmentally friendly Eco-Effect™ technology uses 100% recycled ABS material for our floor systems.
