How can you see what the swimming pool tiles will look like AFTER the water has gone in? It all looks so different once the water has gone in. Is it practical to make a mock up somewhere and then put water in to see how the main pool will look? To explain,I've started tiling and at 30% I worry that it won't look like I want and I would sooner chip all the tiles off now rather than go all the way and then after the water goes in it looks awful. You've only got to look at a pool which looks great and run your eyes to the tiles at the top of the pool where the water doesn't reach and you can see how they look compared to the SAME tiles which are covered by the water. Completely different .
