To me, the best tile for a fiberglass pool is a solid 6x6 tile. They are quicker to install, have fewer grout lines for a less busy look, and tend to hold up the best.
At the end of the day though any frost-proof tile can be installed on a fiberglass pool. We are partial to the National Pool Tile Brand but there are several others that are just as good.
One of the biggest trends in pool tile over the last few years is the Glass tile as seen on the pool in the picture above. This was a River Pools model R32 in the color Maya Shimmer which we installed EQX Midnight 2x2 glass tile to the right.
It's a unique tile that almost changes colors depending on where you are standing in relation to the pool. It really popped against the dark blue gelcoat of the fiberglass pool.
Waterline Pool Tiles come in 4 sizes, 6"x6", 3"x3", 2"x2" and 1"x1". There are also mosaic,deco and stone look tile options available at https://www.nptpool.com/tile/
This tile takes a bit longer to install and more adhesive and grout so it is a little on the more costly end of tile. To tile the average size pool it costs around $3,800.00 to tile a pool with a solid 6x6 tile, $4,200.00 to tile with a 2x2 glass tile, and $4,500.00 for a 1x1 glass tile.
As you can see waterline tile gives a fiberglass pool a more finished and refined look. While not necessary, waterline tile is the first upgrade I would recommend to any new pool owner.
