They are fully water proof, the high gloss finish will not fade and a very easy to clean also with the manufacturers minimum guarantee they will be just as good in 10 years time.
Do not become brittle
Easy to wipe down/ polish
Less mess than digging out the old shower and reinstating new tiles
No hunting round trying to match obsolete/ discontinued tiles.
Never have trouble replacing or repairing that shower ever again !
No new tiles or tiling required.
