HST Pro-Tex spa cover for Cal Spas – 93 x 93 in, black

Replace your compatible Cal Spas cover with this 93 x 93 in black Pro-Tex HST cover. Its 5 to 3 in taper, full thermal seal, and welded 6 mil vapor barrier help retain heat between uses. This configuration has 8 in corner radii and a 5 in overlap skirt: measurements to compare with your current cover before ordering.

93 x 93 in: choose according to your Cal Spas configuration

The Cal Spas brand includes several models and generations. This HST replacement cover must match the shape of your spa, not just its length and width. Also compare the 8 in corner radii, 5 in skirt, fold direction, and strap positions. The radius describes the corner’s curvature; it does not represent a straight 8 in cut.

Insulating construction with a 5 to 3 in taper

The taper promotes water runoff from the surface. The full thermal seal and central overlap skirt help limit openings through which heat can escape. The welded 6 mil vapor barrier protects the interior against moisture transfer. A properly fitted and closed cover helps retain heat; its maintenance and operating conditions affect its performance.

Black Pro-Tex and rubber handles

HST describes Pro-Tex as solution-dyed polyester coated with polyurethane to protect the surface against water. The materials are UV-treated and mildew-resistant. The manufacturer states that the fabric is 25% lighter than vinyl; this comparison concerns the covering material, not the cover’s total weight. The two rubber handles provide a suitable grip for handling.

Prepare for the replacement and check your lift

Identify the spa model and year, then compare your current cover with the measurements on this page. If you use a cover lift, verify that it accommodates the shape, thickness, and fold of the new cover. Provide photos of the spa, hinge, and straps to confirm your selection.

Installation and maintenance

Place the cover evenly around the perimeter and check the strap alignment. Gently release the seal before lifting with the handles; the skirt is not a handle. Clean regularly with a soft cloth, water, and mild soap. Carefully remove snow with a broom, not a shovel, and drain standing water to preserve the cover’s shape.
