New shower, Marbelite?

[littlemisssunshine]

I'm doing a total overhaul of my master bath. We have a huge shower with glass doors that while we want to keep the shape and size, we are thinking of using something other than tile. We currently have white tile and white grout and it is always dirty, no matter how much I scrub. Has anyone used marbelite and or have opinions on it? Or is there any other material to consider? Or you could just suck it up and tell me to do tile again....and make suggestions on color! TIA!
