Croydex Matt Black & Chrome Multi-Function Toilet Butler

Does what you want. Saved drilling into tiles. The shelf on top is very useful.

We wanted a toilet roll holder that didn't need to be drilled onto the wall and this was made for our needs along with a handy toilet brush. It hold extra rolls so no need to run out, and be left short. It also has a shelf to store your mobile so you don't drop it down the toilet.
