Why do I need to provide measurements for my new spa cover?

Accurate measurements are essential when ordering a new spa cover to ensure it fits perfectly. Here’s why providing precise measurements is so important:

Variations in spa dimensions

Manufacturers may adjust the dimensions of spa models over time. Even if you own a specific model from a certain year, there may be multiple cover sizes available based on the production run.

Custom fit requires exact measurements

We need the length, width, and corner radius of your spa (or your existing cover) to provide a cover that fits correctly and offers optimal insulation.

Non-refundable purchase

Spa covers are a significant, non-refundable investment. Providing accurate measurements helps avoid costly mistakes and ensures you receive a cover that will serve you well for years to come.

What is the "R" Value on a Spa Cover? (Corner Radius)

The R value, or corner radius, measures the curve on each corner of a spa cover. This measurement is critical to ensure the cover fits snugly and insulates your spa effectively. A corner radius that’s too small or too large can result in poor fit and reduce the cover’s lifespan.

Watch: How to measure your spa cover correctly

To enable us to recommend a cover that will be the best fit for your spa, we need you to take some measurements of your existing cover.

If you don't have a cover currently, you can follow the steps below to measure your spa.

1. Measure each side

Measure the outside dimensions of your spa. (Do not measure the inside edges)

2. Measure the outer radius

Use two rulers or straight edges on each edge of a corner. Measure from the beginning of the curve (R1) to the point where both rulers or straight edges meet (R2)

3. Measure the lip of your spa

Measure from the top surface of the spa shell down to where it meets the cabinet. For an in-ground spa, measure from the top surface down to the deck, or tile.

4. Measure the location of catches

Measure the distance (T1 & T2) from each outer spa edge to the centre of the catch. If there is more than one catch per side also measure the distance between catches (T3). Then measure from the top of the spa (not the spa cover) down to the center of catch (T4).
