Use one of these to prevent tiles cracking when you hand the toilet. Thank me later.

Interesting! I’ve fitted many a wall hung toilet, directly onto tiles and never had an issue with a tile cracking (always making sure the tiles are well bed), BUT I like the idea of this. Do you use them often? Or always?
Come to think of it I did once purchase for a client an all in one kit (cistern frame, toilet and seat, all in one box) from fluid master and it had one of these foam things in it that was fitted between toilet and tile. Was not really sure what it was there for but fitted it anyway
