This one is the 21 foot round with a 54 inch wall. That pool holds 9,930 gallons, and that is the number to work from when you size a heater, a pump or a chemical dose. Measure the pool and read the wall height before ordering rather than after.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eResin top rails\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe Coronado is listed under resin and hybrid, and the top rails on this build are 8 inches. Resin trim does not rust the way painted steel does, which is the usual reason owners of older pools look at it when they rebuild.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWater type\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis pool is rated no for salt water.
