Nancy's shower is one of those that you REALLY do not see. It is a secondary bath, with a small 3 1/2 x 3 1/2 shower, with a glass door. When I say that you don't see it, I really mean it. You would see the door- that's it. With a shower as small as that- I would definitely go with a white.
So- what solid surface? There are a lot to choose from out there. The top photo is Corian- a great practical surface with a nice heavy, rich feel to it.
