It's for life you know. Through thick walls or thin. You promised...



Mr B thinks the walls are too thin.
If it were up to me, there would be holes and shelves everywhere. However, we share the house and so I cannot go round drilling holes and putting up shelves.

Which wall is this then?If he knows nothing of DIY then he should not be entitled to comment on it, the walls will be thick enough. Or they wouldn't have a shower on them.
Even a thin plasterboard wall using plugs/screws will hold a shelf over time better than glue, even more securely if fixing through a layer of tile and tile adhesive.
Do you not fancy drilling through tiles? As has been said it's easy, you don't even really need a tile bit. Check there is no pipework/electrics in the cavity. Put PVC tape over the area to be drilled (stops drill skating over the tile), mark the spot on the tape. Use a 5.5mm masonry bit in a variable speed drill. Make sure the drill is NOT set to hammer action! Start slow until you feel the drill bit break through the glaze, then speed it up and push through. Insert red rawlplug and use #8 screws (#10 for a tighter, more secure fit). Done.
