I don't have one, but I vacationed once for 2 weeks in Mexico and the hotel pool was all tile. I was in the pool daily. It had very small tiles, I found it slippery but eventually got used to it. At times I would also find a tile that was not set flat and a corner would be raised, the end result was usually a cut foot. After two weeks the tile didn't bother me and I knew what areas to avoid cut feet. I guess it's all personal preference. No idea what chalenges if any there are with chemistry.
