Measuring Tips

When measuring for your new spa cover, it is best to have two people help with the measuring, "one to hold and one to read". Exact measurements are not crucial, however, you DON'T want to make the cover too small. When in doubt make it a little larger (about an 1") than the final measurement. A cover a little bigger will never be noticed, whereas one too small will not hold the heat in. It will allow leaves and dirt in and will not look attractive. So, please confirm your measurements before sending in your order.

Should I measure just the spa (acrylic), or should I include the wood rim?

This is a personal preference, however most folks measure just the spa acrylic, lip to lip. (See figure below). In some cases you may want to measure to the wood rim, only because it may look better to you and it doesn't create a "rim" for leaves and other items to collect on. It does not help one way or another with energy efficiency.

Another thing to consider is the cover skirt/flap, you will want this to hang STRAIGHT DOWN. So, if the lip of the spa is at an angle, make sure you measure the cover long enough to achieve this. You don't want the skirt sticking out by measuring your cover too short. Also, measure the skirt (3" is standard) long enough to cover the spa lip, or the spa cabinet rim. (See figure below)

Measuring a Radius (round corner)

Measuring a radius is not that difficult once you know how (See figure below). The key is to NOT make it too big, this is just the opposite of measuring your spa cover. If you measure the radius too big, it WILL NOT cover the radius corner (See figure below). However, if you measure it too small, it will be just fine. It may hang over a little but there will not be a noticeable difference. When in doubt,take the smaller measurement.

The distance between the corner of the carpenter's square and the place where it touches the spa (A) equals the radius of the curve (B).

In this example the cover radius was measured too BIG. Therefore it did not fit the spa. Remember, if in doubt, take the smaller measurement.

In this example the cover radius was measured too SMALL. The orange represents how the cover extended past the desired location. If a mistake in measuring is made, measuring too small is better than measuring too big. As you can see, it will still fit the spa.
