Cal Spas Specially-designed cabinet frames are treated to resist rot, corrosion, and invasive pests and insects. Our American-made Pressure Treated Cabinet Frames are construceted using 1-inch galvanized steel fasteners, corner gussets, and vertical angle bracings for added beam support.

Unlike our competitors that use metal frames, pressure-treated wood dampens sound and vibration; making Cal Spas the most soothing and relaxing spas in the industry.
