We are renovating our pool and our spa spillover will be 34" wide. We were originally set to have a solid stone spillover but then it was discovered the stone didn't come in a long enough piece . Our choice now is use the stone in 2 pieces with a grout line or use a solid piece of granite. I have read a few threads here that there have been issues with grout lines messing the flow of the water. I have also read that the granite should have a "drip groove" cut into the bottom so the water does not flow under and down the tile . If anyone can give me your opinions on both I would be grateful. Also the spillover will be 2" , does that sound enough to prevent the water going under and down the tile? and a square edge not round on the granite edge? Trying to educate myself on this progress. Thanks!
