The easiest way to order a new spa cover is to order by make and model from our database of over 100 different spa manufacturers and over 1000 different models. But, when your not sure, or want to make sure you get the best fitting spa cover, the best thing is to measure your existing hot tub cover.
In just a few steps, and with just a tape measure and our order form, I’ll show you how to order a perfect spa cover every time.
The most common question we get is “What should I measure?” If your current hot tub cover is in pretty good shape, you can just measure the existing cover. If it’s in really bad shape, then you’ll measure the tub instead.
The most important thing is that your measurements be from outside acrylic to outside acrylic. Don’t measure to the outside of the spa cabinet, but just to the point where the spa shell ends.
The most common shaped hot tub is a square or a rectangle, that’s about 85% of hot tubs. If you have a hot tub made after 1985, chances are it has rounded corners. The most common hot tub covers we make are rounded square, or rounded rectangle. If you have a different shaped hot tub, don’t worry, these principles will apply as well.
The first thing to make note of is where the fold is, or which direction the fold of your spa cover is running. On our measuring form, you’ll notice that the “A” measurement is always cut in half by the fold of the spa cover. So the first measurement of a spa cover is straight across the cover, and across the fold. Write down this first measurement down.
The next measure is the “B” measurement, taken across the cover, perpendicular to the first measurement. Write down this measurement.
“C” is the third measurement that we take is to determine the radius, or the curvature of the rounded corner. There are two ways to measure this, with a carpenter’s square, or with a measuring tape. The measure is taken from where the curve begins to the point where it intersects at a 90 degree angle, with a straight edge, or yard stick held on the adjacent edge of the cover, as shown in the image above.
The curve could be very slight, a 4″ radius, or they can be 12″ in some cases. It’s important to carefully measure the corner radius, to have the best fitting spa cover.
Next, we’ll measure the length of the spa cover skirt and the straps. On our website, we have default values – for the most common measurements, but you can enter your own. The skirt should hang down long enough to cover the acrylic on the spa, to protect it from the UV rays. Measure the length of your current spa cover skirt, from the bottom of the cover to the edge of the skirt. Shown in this image, we have a 5″ spa cover skirt length.
Now you can measure the safety strap, in the same manner, from the bottom of the spa cover, and including the skirt, to the buckle – but not including the buckle. Our new spa covers include 2 safety straps, with standard buckles to fit your existing strap locks. We also include the complete hardware kit if you want to change the entire lock. Write down the measurement of your spa straps. Shown in this image, we have an 8″ safety strap length.
And that’s it! Just 5 pieces of information necessary to order a replacement spa cover from Hottubworks. You can always order by make and model, but if that information isn’t handy, you can measure your own hot tub in just a few minutes.
