Square Spa Cover
With Rounded Corners

It is best to measure your old cover if you have it available, otherwise please read the instructions carefully.

Whether you are taking measurements for a replacement spa cover from your old spa cover, or whether you are taking measurements for your new spa cover by measuring the tub, follow these directions carefully for a perfect fit. Please view our exclusive video for helpful hints.

Measuring a square-shaped hot tub isn’t very tricky, unless the corners are rounded. You’ll need a carpenter’s square or a corner radius chart to do the job. Double-check your corner measurements, because if the radius is measured incorrectly and is too large, your new spa cover may not cover the tub completely. Always go with a smaller radius if you are unsure of your measurements—Your new hot tub cover might overhang a little bit, but who will know?

Most people prefer to measure the spa from the acrylic tub, lip to lip (see our diagram below). Or you might wish to measure from the wood rim if you are concerned about having leaf litter and other debris sitting on top to the rim. Either way, the hot tub will retain its ability to be energy efficient.

The skirt flap of your new hot tub cover is also important to consider when taking measurements: you will want the skirt to hang straight down. This is easy to achieve when you allow for plenty of room below the seam of the tub. If it’s too short, you could be compromising the cover to lie flat and seal the tub properly. Therefore, take the skirt measurement and add at least 3” to cover the spa lip and the cabinet rim. (Again, view the figure below)

A final note: Go for a bigger spa cover when taking measurements. It’s important that your new or replacement spa cover shields the entire tub. A cover that is too small will not fit correctly, buckling on top and allowing precious heat to escape.
