Why Accurate Measurements Are Essential

Ordering a new spa cover with precise measurements is crucial. Here’s why:

Energy Efficiency: A snug, perfect fit is the most important factor for trapping heat, which saves you money on your power bill.

Protect Your Spa: A properly sized cover keeps out rain, leaves, and other debris, keeping your water cleaner for longer.

Avoid Costly Mistakes: Most spa covers are a non-refundable purchase. Taking a few minutes to measure accurately ensures you get a cover that will serve you well for years.

Understanding the Corner Radius (The "R" Value)

The corner radius is the measurement of the curve at the corners of your spa. Getting this right is one of the most important steps for a perfect fit. A cover with the wrong radius won't seal properly, leading to heat loss and a shorter lifespan for the cover itself.

4 Simple Steps to Measure Your Spa

Step 1: Measure Length & Width
Measure the outer lip of the spa shell from edge to edge (do not measure the inside). We recommend adding 20mm to each measurement to allow for a slight overlap.

Step 2: Measure the Corner Radius
Place two straight edges (like rulers or a builder's square) flush against a corner. The distance from the point where the rulers meet back to the point where the spa's curve begins is your corner radius.

Step 3: Measure the Skirt Length
Measure from the top surface of the spa shell down to the top of the cabinet. This determines how long the cover's "skirt" will hang down.

Step 4: Measure Latch Locations
Measure the distance from each outer edge of the spa to the centre of the catch. Also, measure from the top of the spa shell down to the centre of the catch.
