Engineered for Quality

Engineered for energy efficiency and high R-value, every cover we make combines two heat seals and high-density foam inserts to keep the warmth inside while the weather stays out. All our spa covers are tapered to shrug off water and sealed in 4-mil polyethylene to prevent moisture absorption.

The strength of your spa cover is very important, especially if you have small children or large pets, or live in an extreme climate. For your peace of mind, all King Spa Covers models are manufactured to meet or exceed the rigorous standards of the ASTM.

We offer 3 different thicknesses of spa covers, the thicker the cover, the stronger & more energy efficient it is.
