What is the best shower bench?

I bought a condo with a big shower stall in the master bathroom. It is really cool, but there is no place to sit in the stall, and my girlfriend likes to sit and shave her legs and whatever else in the shower. Her place has a built in seat. So I was thinking of getting one of those wooden benches. I guess teak or redwood would be the right material. I need a maker or supplier of a good product. I will pay for one that lasts. Any suggestions?
