Hi all. I have recently moved into a new home and I need to extend tiling around a bath/shower because paint is peeling and I am afraid of water damage long term as paint get really wet when having shower. This is a simple job but I just can't find tiles to match old ones. All I need is plain white gloss rectangular ceramic tiles. 200x300mm. Thin not thick. These should be easy to source but no luck so far. Help!!!
