Measuring For a New Hot Tub Cover
Spa/Hot Tub Cover Measuring Tips
When measuring your spa for a new spa/hot tub cover, there is one important thing to remember: IT HAS TO BE LARGE ENOUGH TO FIT! We can make you a cover in one of two styles. The most popular style is to cover only the acrylic shell. (measurement C in the below diagram).
If you have a spa/hot tub that resembles the diagram below, with a wood edge on the outside of the acrylic shell, and would like your new lid to cover both the shell and the wood lip, MEASURE FROM THE OUTSIDE OF THE WOOD SKIRT (D “Cabinet Size”).
There is no difference in spa/hot tub cover performance either way. It is simply your preference.
- A – This is the height of the acrylic lip. This will determine the cover´s skirt length (“Cabinet Size” covers may require a longer skirt, to the bottom of the “deck”).
- B – Width of wood lip of the cabinet (not present on all tubs).
- C – Outside dimension of the acrylic shell (standard cover size).
- D – Outside dimension of the wood cabinet.
Some covers have rounded corners. The diagram above shows a rounded corner with imaginary dotted red lines. The length of the red line represents the measurement of the radius corner. The lines start where the cover begins to curve, and end where they cross. Be sure to measure all corners and that they are ALL the same size! IMPORTANT: If in doubt, a slightly smaller radius will slightly over hang the spa while a larger radius will not cover the spa completely.
Some covers have cut-corners. The diagram above shows a cut corner with the length of the redline representing the measurement of the cut-corner. Be sure to measure all corners and that they are ALL the same size (some covers have different cuts)! IMPORTANT: If in doubt, a slightly smaller cut-corner will cause the cover to slightly over hang the spa while a larger cut will not cover the spa completely.
When measuring an octagon spa, it is extremely important to get dimensions on all sides of the tub.
The example above shows an octagon (eight sides). Its length & width measurements (9 & 10), and the side measurements (1-8), are ALL EQUAL. If they are not equal, it is not a true octagon, but more than likely a cover with cut corners.
More measuring tips:
- Measure both your spa and your old cover, if possible.
- Specify If Your Cover Lifter Attaches to The Cover!!!
- Make sure the measurements are big enough. It is okay for the cover to be big. It still does its job. However, a cover too small will never do the job it is supposed to.
- Measure all sides of the spa.
- Measure the overall length and width of the spa.
- Be careful when representing the dimensions in our order forms.
- Specify hinge direction.
Advanced Rounded Corner (Radius) Measuring Tips
If your existing cover fits properly, set it upside-down on top of a piece of newspaper. Line up the edges of the newspaper with the edges of the cover. The distance from the corner of the newspaper, to where the cover completely covers the paper is the radius of the corner.
You can also use a framing square to measure the radius of your spa corners. Set the square against the edge of the spa as shown below. The radius of the rounded corner is the distance from the inside corner of the square, to where the cover just touches the square.
The diagram below shows the pitfalls with miss-measuring a rounded corner. The green line represents a measurement of too large a radius, while the red line represents a measurement too small. As you can see, with too large a radius the cover wont completely cover the spa. Too small a radius and the cover simply overhangs a bit. If in doubt always go with a slightly smaller measurement. The cover may be slightly large and overhang the corner a bit, but it will cover the entire spa…… and no one but you will ever know.
Advanced Spa Cover Measuring Tips for Difficult Corners
Using masking tape, simply extend the lines of your spa (or existing cover) as shown below. Where the tape crosses is where you want to measure from. In the diagram below, “A” is the measurement of the cut-corner. If you don’t have any tape, a yardstick (or other small piece of wood) will also work.
