Tile size 331mm x 232mm???

[burts]

Evening,
I am a plumber, I’ve replaced a shower tray which requires a tile repair. Same tile not an issue but the tiles I’m trying to match appear to be 232mm wide x 331mm long?
Can someone tell me if there was a common size tile around this size, about 20 years old ans where I could get some?

Thanks

not sure colour but these do a huge range of tiles and may do something
