If you need extra shelving in your shower there are many options available to you. The simplest and least expensive would be to use a shower caddy that either hooks on to the shower head or sits on the corner ledge of the bath. The most elegant, however, could be a simple shelf mounted on the wall. The sleek and simple look of stainless steel is perfect for bathrooms, not just because of its resistance to rust, but also because of its semi-reflective surface.
Here a model that makes me wish I had an ultra-modern bathroom:

Don’t forget that mounting a shelf in a bathroom is not always a simple job.
