I am an architect designing a pool for a custom home. We found a nice large format tile from the Netherlands that we would like to use for the waterline tile. The manufacturer confirmed that it will work in a pool. It's dimensions are 3.75" high by 23.5" wide. My questions are:
1. What is the recommended height of waterline?
2. Why must we have waterline tile? Is it possible to simply run the pool plaster all the way up to the underside of the coping?
Thanks in advance for you help!
