My pool remodel project should start next week. As you see in attached photo, I will replaster with Wet Edge Altima Blue, replace tile, concrete coping with flagstone and pebble deck with pavers. I will replace my cement deck with cement pavers, but still debate if I should use stone or travertine for coping. The stone in the photo is what I have for coping in the contract, but if i change it to 4x12x2 travertine then will add $2600 for 86 linear feet. Will it worth it to go with travertine? My concern with flagstone is the sharp edge when I have my grandkids in the pool. What are pros/cons of either? Thanks for any suggestions.
