Spa Cover Measuring Tips - the easy way to do it right:
  1. Your new Spa Cover Spot cover will be made to dimensions you provide.  Since you're responsible for accurate measurements, use a tape measure & double-check your figures.  It's easy, and we show you how.
  2. Length and width measurements are in inches, rounded up to the nearest inch because allowing a little extra is a good practice. A spa cover that is a little larger than the acrylic shell will work just fine, but a cover that is too small will be tight or may not fit at all.
  3. Dimensions are best taken from the spa or hot tub first (not the old cover).  If your old cover fit correctly, compare your measurements to those of your old cover for verification.
  4. Covers over 96" length or width are oversize at additional cost. Please email us for a price quote.
  5. A spa cover skirt is the portion of your fabric that extends down from your cover bottom and overlaps the top of your spa. Cover skirts help protect the acrylic part of your spa from UV damage so it's important that they hang down enough to cover the acrylic. Measure from the bottom of your existing cover down to where the acrylic stops and the cabinet starts.
  6. Sorry, we cannot make covers for spas with obstructions or features needing special cutouts, flaps, or hoods.
Spa Conventional

Conventional Spa Cabinets (most spas)
Most newer spas are made as shown in figure (A) with the acrylic shell lip slightly overhanging the spa cabinet paneling. These spas are very easy to measure from the outside edge of the shell.

  1. Measure the required overall shell dimensions.
  2. The spa cover skirt covers the lip of the shell as shown (right).  Our standard 2.5 inch cover skirt length is normally ideal for these spas, but you can specify any length you require.
  3. The vast majority of spa covers are made as shown here.

Spa Cabinets with Wooden Edge Rim
If your spa resembles this spa with a wood edge around the outside of the acrylic shell lip, you have a choice as to how your cover can be made:

IMPORTANT: On Soft Cover orders please measure from the outside wood ledge. Soft Covers come with an 12" skirt that will come down over the wood edge.

Skirt conceals only acrylic shell lip & sits atop wood edge 

  1. If you prefer to have your spa cover sit atop the wood edge, then measure acrylic shell dimensions and skirt length.
  2. Make skirt length about 1/2" shorter than distance from top of spa shell to top of wood edge rim, so that it does not bunch up against the wooden edge of the spa cabinet.  This will allow the cover to seat positively against the shell.
  3. This is the default cover construction for spa cabinets with wood edge rim, as shown right.

Skirt conceals shell lip & overhangs wood cabinet edge rim.

  1. If you prefer to have your spa cover's skirt overhang the wood edge, then measure overall cabinet dimensions above to make a slightly larger cover than example.
  2. Determine skirt length long enough to cover the wood edge.  Measure from top of spa shell to bottom of wood edge rim.

Inset Acrylic Spas
If your spa's acrylic shell is set directly into a wooden deck or built into a concrete surface.

  1. Be sure to take overall outside measurements of shell length and width (NOT the inside opening dimensions) so that your cover will seat correctly and cover the spa shell's acrylic rim.
  2. Make skirt length about 1/2" shorter than distance from top of spa shell to top of deck, so that it does not bunch up against the deck surface.  This will allow the cover to seat positively against the shell when closed.

In-Ground Concrete or Plaster Spas

  1. Be sure to add at least 6 to 8" to the opening dimensions (length and width) so that your cover will be supported properly and extend past the spa opening at least 3 to 4" on all sides per (X) above.  Example: spa opening is 70" x 80"; order cover 78" x 88".
  2. This type of cover is sometimes made with no skirt.

How To Make A Spa Cover Template
For an odd-shaped spa, you can easily make a template which we can use to make your cover. From any home improvement store, obtain the following supplies to make the tracing.

  1. Clear Plastic Painter's Tarp
  2. Roll of Masking Tape
  3. Permanent Marking Pen.


  1. Drape the clear plastic over the top of the spa.
  2. Tape the plastic to the sides of the spa cabinet of platform surface. (If in-ground or in-deck spa)
  3. When plastic is taut, first write the word "Top" on it, the trace an outline of the spa shell using a felt tipped permanent marker, leaving a little extra (1/2" or so) all around the perimeter.
  4. IMPORTANT: Be certain to mark "Top" on the side of the template. Otherwise, your cover could be make incorrectly as a mirror image of your spa. Also, write your name and phone number on the template.
  5. For in-ground spas without rims please add at least 6-8" to the opening dimensions (length and width) so that your cover will be supported properly and extend past the spa opening at least 3-4" on all sides.
  6. Please email us for more information and for the mailing instructions for the template.
