Description
Coast Spas solar bubble cover that floats on the water to slow heat loss and cut evaporation. Its insulating bubbles form a thermal layer under the main cover, which can trim heating costs and reduce how often you need to add water. It is light and simple to lift in and out. Trim or check the fit against your spa's water surface before use.
