SpaUmbrella® Undermount Base Plate – Hot Tub Umbrella Accessory

Q: Do I need to drill into my spa cabinet to install this base plate?

A: No — the undermount design allows the base plate to slide under the spa skirt or into a deck opening, avoiding direct drilling into the spa shell.

Q: What umbrella pole diameter does it accommodate?

A: It supports umbrella poles up to 2¼″ in diameter.

Q: Can the umbrella rotate and tilt while mounted?

A: Yes — the base plate provides full 360° rotation and tilt adjustment via a crank handle for flexible shade coverage.

Q: Is the base plate removable for off-season storage?

A: Yes — it is designed to be removed easily for storage when not in use or during high-wind conditions.

Q: What materials is the base plate made from?

A: It is constructed from powder-coated or zinc-plated steel engineered to resist corrosion, spa chemicals, and outdoor exposure.

Power off the spa circulation and clear the area under the spa skirt or deck cavity.

Slide the base plate into position beneath the spa skirt or into a prepped deck opening.

Align the bolt holes of the base plate with the structural frame or deck surface.

Secure the base plate using appropriate lag bolts or screws through the designated mounting holes.

Insert the umbrella pole (up to 2¼" diameter) into the base sleeve and tighten clamp or bolts to lock it into place.

Adjust the umbrella tilt using the crank handle and rotate for desired coverage.

Remove the umbrella or base plate for winter storage or high-wind conditions.

Inspect periodically for hardware loosening and tighten or replace as necessary.
