Teak is fabulous in a bathroom.

Using teak in any style bathroom works well. In modern spaces, it warms and softens without taking away from the sleek styling.  For traditional spaces, it's beauty adds to the use of stone and glass.  As a shower floor, it's fabulous.  Adding a teak bench to a shower is simple and safe, and shelves - placed nearly anywhere - add storage in a beautiful way.  I place teak mats outside the shower to help with slip resistance, raise the floor surface to make it easier to step out, and to look warm and rich in the bath.
 Here are some inspirational images on ways to incorporate a bit of teak in your bath.
