How do I measure the skirt length for my replacement hot tub cover?

Measuring Hot Tub Cover Skirt Length

The Skirt Length is the length of the flap that extends below the foam on your spa cover. The purpose of this flap is to protect the acrylic lip of your spa from weather damage.  It also helps to prevent wind debris from getting under your cover. As a rule of thumb, the skirt should by 0.5 inches longer than the acrylic rim of your spa to protect it. Do not include the foam in your measurement.

Our covers come in skirt lengths ranging from 0” (no skirt) to 7”.  Measure from the bottom of the foam (or rim of your spa) to the bottom of the flap. Round up to the nearest half inch.
