I have a in ground spa with a round fountain front an infinity edge at back. I wanted a custom cover for the whole thing that could be lifted off for use. This company took on the challenge and made the best custom cover ever. I can open it in sections by myself to use seated area for instance. The reason I had it made was because I was sick of leaves going in the overflow(ground level) and in spa. Not only is this superheavy duty cover doing that the spa also maintains the heat from the day before or heating. We’ll save a ton of money. And thanks to Scott for taking on a complex project and the cost was VERY reasonable.
