Carrara marble pool waterline
We are resurfacing our pool at the moment including the replacement of the waterline tile. We would like to use a carrara marble mosaic (see attached picture) that is 3/8" thick. The marble is honed so that etching should not be a huge problem. Would this kind of marble be suitable for a pool waterline? Does anyone have experience with a marble waterline?
One tile guy was concerned that when water gets behind the marble and it freezes, the tile might just come of the wall. However, we are located in Sacramento, California - we have temperatures around 32F for usually 1-2 nights a year. Thank you for the advice!
