Shower caddy/shelf with a back

[SarkyWench]

Does such a thing exist?

We've just had to have our shower replaced and now have an unsightly (but watertight) hole in the tile about 10cm x 10cm at about chest height.
I thought I could cover this up with a caddy/shelf but can't find anything with a back to cover the mess behind.

Or is there another solution that I'm missing?

Thanks

Anyone?

Not sure I understand... Do you mean a recessed box?

Nope. Sorry for not being clear.
We basically just have a missing section in the middle of a large tile with a load of filler where the tile should be.
