There’s an old saying, “The devil is in the details”. When it comes to your hot tub, that devil can be a poorly fitting cover. We’ll show you how to measure your hot tub cover perfectly, ensuring your hot tub stays warm, clean, and inviting all year round.

Why Measure a Hot Tub Cover?

Imagine having a lid that doesn’t fit your pot. What a pain in the neck, right? This same principle applies to hot tub covers. A hot tub cover that doesn’t fit properly is more than just an eyesore—it can lead to increased heating costs, quicker wear and tear, and even safety risks. So, let’s roll up our sleeves and delve into the nitty-gritty of how to measure hot tub cover.

Energy Efficiency

Did you know an ill-fitting hot tub cover can ramp up your energy bill? Indeed, an oversized cover can lead to heat loss while an undersized one may leave portions of the tub exposed. A snug-fitting hot tub cover prevents heat from escaping, thereby saving on energy.

Increased Lifespan

Like a snug coat in winter, the right-sized hot tub cover safeguards your tub from adverse weather conditions, increasing its lifespan. By protecting your hot tub from the elements, debris, and harmful UV rays, a properly measured cover plays a critical role in the long-term maintenance of your hot tub.

Essential Tools for Measuring a Hot Tub Cover

Let’s get down to brass tacks. To measure your hot tub cover, you’ll need a few tools on hand. Nothing fancy, just a tape measure, a pen, and a notepad should do the trick. Here’s how you can use these tools to ensure a perfect fit.

Tape Measure

Grab a retractable tape measure from your toolbox. If you’re stuck in a pinch, a ruler or yardstick could work too, although a tape measure is more flexible and accurate for this task.

Pen and Notepad

You’ll be taking a few measurements, so keep a pen and notepad handy. Trust me, it’s way too easy to forget those numbers in the hustle and bustle of daily life!

How to Measure Hot Tub Cover

Alright, it’s game time. Let’s walk you through the process of how to measure your hot tub cover. This process will be as easy as pie once you get the hang of it.

  1. Measure the Length: Using your tape measure, find the length of the hot tub from one side to another. Make sure you measure from the outer edge of the acrylic shell, not the skirt or lip of the tub.
  2. Measure the Width: Repeat the same process to find the width of your hot tub.
  3. Measure the Radius of the Corners: If your hot tub has rounded corners, you’ll need to determine the radius. A simple way to do this is by measuring the distance from the point where the curve starts to where it ends.
  4. Measure the Skirt Length: The skirt is the flap that hangs down from the cover. Measure this from top to bottom.
  5. Measure the Strap Length: Lastly, don’t forget to measure the length of the straps. The straps secure the cover to the tub.

Common Pitfalls to Avoid

Keep an eye out for these common mistakes during the measuring process. Better safe than sorry!

Forgetting to Measure the Radius

If your hot tub has rounded corners, forgetting to measure the radius is a big no-no. This can result in an ill-fitting cover.

Ignoring the Skirt and Straps

The skirt and straps play a crucial role in ensuring a secure fit for the cover. Ignoring these components can lead to poor insulation and a cover that may blow away in the wind!
