Square Spa Cover
With Cut Corners
Should you use an existing cover or should you take measurements directly from your tub? It’s always best to use an old spa cover, if it is still in good condition and not warped and buckling. If you don’t have one, then taking direct measurements from your tub is easy for a square shaped tub with cut corners. Review the instructions below, along with the accompanying diagram. For more information, see our exclusive video.
To measure for a square-shaped hot tub cover, measure one of the sides. Obviously, the length of each side should be exactly the same, so you won’t need to measure every side. However, if you are unsure, you could always confirm your figures by taking measurements of another side. Next, measure the length of a cut corner (again, each cut corner should have the same measurement). You might also want to indicate where your tub controls are, and then measure the length behind the controls to indicate where the fold will be located (you’ll want the fold behind the controls, enabling easy access).
Should your measurements include the wood rim, or should you measure just from the acrylic of the spa? Most people measure from the spa, lip to lip (view the following diagram). However, you may want to measure from the wood rim if your tub is located under trees where leaves and debris might collect on the rim. Either way, your cover will keep your hot tub energy efficient as long as your new spa cover or replacement spa cover lies flat over the water.
To ensure that it will lie flat, you’ll also need to measure for the skirt or flap below the seam of the cover. It needs to hang straight down and not fold up at all, so make sure that your measurements are at least 3 inches in length to cover the spa lip or the spa cabinet. If this skirting is too short, it could fold up, letting heat escape.
When taking measurements for the skirt, as well as all other measurements for your new spa cover or replacement spa cover, be generous with your figures. Bigger is always better, so add an extra inch to each of your measurements. After all, if your cover is too small or too tight, your cover will not lie flat and won’t do its job.
