When ordering a replacement spa cover, after selecting the cover thickness and colour, you will need to provide us with the measurements relevant for the geometric shape of your particular spa. Click in the circle that is above your spa cover shape and note the measurements we’ll need from you. You will usually need the length; width; “corner radius” or length of cut corner; and “skirt length”. Measure along each required edge depending on the spa cover shape. For example, when ordering a rectangular cover with square corners, you would click the button above the Rectangle and then measure and fill in the required dimensions (in this case “A” and “B”.) Please provide all measurements in inches.

For rounded corners, you will need to measure the Corner Radius which is the distance between where the spa corner begins to curve and the corner point where both sides of your cover would meet if they had not been rounded off. The picture at left shows how to measure your corner radius if you do not have a carpenter’s square. All you need is a tape measure and a straight-edged object like a yardstick or a strip of plywood.

Simply place the straight edged object along one side and measure to it with your tape measure from the point where the spa cover starts to curve as shown in the picture. When in doubt, a slightly smaller radius is better to avoid the corners not fitting. For example, if you think it is between 6 or 7 inches, you would want to enter “6” The smaller the radius, the more material is left across the corner of the cover. If you give too large of a radius, the corners may not fit.

After you have entered the measurements for the shape, scroll down a bit further to enter your “Model” and “Make” of spa. If you do not know this information you can just enter “N/A”. Right below is where you fill in your Skirt Length. The word “skirt” is often used to refer to your spa’s surround or cabinet. What the skirt length tells us is the amount of vinyl material that you want us to leave around the perimeter of the cover so that it covers your spa shell’s lip. It will normally be between 2”- 5” for most spas. Your preference is what is important here – some spa owners want to cover just the shell’s lip, while others want it to drape a bit further.

By all means, feel free to give us a call on TheHotTubSuperstore.com toll-free line 800-519-7695 with any questions about your measurements.
