Just finished digging a 50x16 pool with spa. The spa will be within the pool rectangle, and the two inside spa walls will be spillways, so in constant contact with saltwater (partially submerged even). We would like to use double bullnose coping stones on top of the spa wall, instead of tile. Is there a type of stone we could use that will not be affected by the saltwater?
Thank you for your help!
