All US Spa cabinets are enclosed with furniture grade clear redwood panels.  The US Spa cabinets are supported three inches above the ground by a vacuum formed ABS plastic base called “Durabase”.  This protects the frame and internal components from moisture, pests and weather. The interior of the spa will be dry and safe even if the spa is surrounded by a pool of water.  US Spa has engineered and vacuum forms the ABS base pans in-house to assure precision fit to each of our spa models. The fitted “Durabase” base pan also provides a distinctive US Spa clean, finished look.  Most manufacturers are content to sit the cabinet on a 3/4" piece of pressure treated plywood or on a pressure treated wood base frame.  This does not effectively protect the frame and skirt panels if the spa is sitting in water. The base also helps prevent visits from pests seeking shelter and end up chewing electrical and plumbing lines.

Support stantions are vacuum formed into the “Durabase” pan to support the spa shell at several critical load bearing points.

To provide additional strength, cabinet corners are constructed of solid 2x redwood. Clear redwood skirt panels are milled on eight head, self joining molders to achieve a smooth, furniture grade finish.  The skirt panels are attached to the frame without screws or nails. US Spa has engineered a unique skirt panel locking system.  US Spa fabricates the skirt panels in-house. Panels are easily removable for access to the plumbing, mechanical and electronic components inside the cabinet. Manufacturing the “Durabase” pans and redwood skirt panels in-house allows US Spa to cut third party supplier costs and pass the savings along to our customers.
