Square Spa Cover
With 2 Cut Corners
The best way to go about measuring for a new or replacement spa cover is to use your old cover. However, if you donít have an old cover to refer to, or if your old cover is buckled and in a state of disrepair, refer to the following instructions, view the diagram below, and view our exclusive video to obtain the proper measurements.
When your tub is square-shaped, with two cut corners (forming a 6-sided hexagon with sides of unequal lengths), youíll need to measure the length of each side. Refer to the diagram below, and make sure to add an inch to each measurement, to make up for any errors when ordering your new spa cover.
Is it okay to take measurements from the wood rim, or should you just measure from the top of the acrylic lining of the tub? Either way will produce an energy efficient hot tub cover, and most people just measure from lip to lip of the acrylic tub lining. But if you are concerned about leaves and debris collecting on the rim of the wood cabinet, we recommend taking measurements from the wood rim. Either way, adding an extra inch to each figure will insure a proper fit. If your new hot tub cover is too tight, it may not lie flat and heat could escape from the tub.
Another consideration for heat efficiency is the skirt or the flap that hangs down from the seam of the cover. Youíll want to be sure that it will hang straight down, long enough to cover the lip of the spa or the wooden cabinet rim (the standard measurement is 3Ē). If your new hot tub cover skirt is too short, it will stick out and cause heat to escape. Please review the figure below.
In summary, itís better to have a new spa cover that is a little bigger than your tub or wood rim. This way, youíll be sure that it seals in the waterís heat properly.
