We used concrete look tiles in our bathrooms, and decided on the same tile (outdoor version) for our pool area. We also used it for our pool coping and waterline tile and edge of the steps. The tiler cut the tiles, and we had a guy come onsite to hone the edges (same effect as the ones in your photo, but same tile on coping and waterline) who did a wonderful job and really reasonable price. This may not be what you are after, but we did not want any glitzy tiles. Photos below

That's a beautiful finish and blends so well with the surrounding tiles. I'm curious what the coping tiles looked like before...are they the yellowish ones that are being painted in the 1st photo, or is that prep work being done? May I ask what was used to prepare the surface so paint would adhere? Great job!

Thanks for that, rach19. I a man no expert but it looks like both issues are happening. I think I detect efflorescence and the grout itself possibly blended poorly. Please call out whoever built your pool (not the tiler as he's not the builder) and complain and say it's not acceptable. There's no way this should be happening so soon.

Hi Emma. As mentioned above, you can select a porcelain tile that is suitable for outdoor use. This can then be installed as your paving, coping and waterline similar to below. I would suggest 100-150mm of waterline tile as below. Otherwise we have installed pavers such as Anston or Stone Outdoors and then matched the colour with a porcelain waterline tile. https://www.anston.com.au/products/pool-coping-step-coping/ https://www.concreteredefined.com.au/pool/ Good luck with your project!
