Hi everyone! We are just constructing a plunge pool on an out island in the Bahamas. Square pool- 9x9x4 ft deep. - concrete with diamondbrite still to be installed. There is a need to keep things simple and easy to maintain because of the location! We are getting ready to order a pump and other parts we need. Looking for recommendations. Also - thoughts about swg vs chlorine. We also just realized we would like a bench in the pool but didn’t install yet. I’d love ideas about a way to put a bench on one wall. Many thanks!
