Zero™ Frost Foundation

---

Cold climates put the greatest strain on a hot tub at the ground level, where heat loss is highest. The Zero™ Frost Foundation is engineered to address this directly by insulating the floor of the spa as part of the core structure.

Unlike conventional hot tubs that leave the floor minimally insulated, the Zero™ Frost Foundation incorporates a full-base insulated, sandwich-structured floor. This construction helps retain heat where it is most easily lost, improving overall thermal efficiency in cold-weather environments.

Many hot tub retailers recommend placing spas on loose Styrofoam sheets to compensate for heat loss through the bottom. With the Zero™ Frost Foundation, this extra step is unnecessary. The insulation is already built into the spa itself—sealed, protected, and designed to perform as part of the foundation.

By insulating the coldest surface of the hot tub, the Zero™ Frost Foundation:

• Reduces heat loss through the base
   
• Helps the heater maintain temperature more efficiently
   
• Improves cold-weather performance
   
• Adds thermal protection to the plumbing area

This isn’t an after-market solution or an installation workaround. The Zero™ Frost Foundation is a purpose-built, cold-climate design that delivers consistent performance without relying on external foam pads.

The result: better efficiency, simpler installation, and confidence your spa is built to handle winter from the ground up.
