I am almost finished renovating my little house in the woods. It's very 'natural' looking - walls/ceiling/floor all tongue-and-groove pine, etc. I built the shower stall myself. The whole nine yards - 1.5" thick wood subfloor, metal lathe, cement, shower liner, more cement, metal lathe, even more cement - it's been a pain. (Yes, this was all required by code.) It's roughly 3' by 6'. For the bathroom floor and shower walls, I planned on tile. Nothing glossy white, a stone-looking neutral (taupe) tile. Maybe a small border of some kind. But I was puzzled as to the shower floor. It has a slope to it (so the water drains properly) and big tiles (6" x 6" or larger) wouldn't work. Well, I found the perfect look today. Small rock slices. Found it at Home Depot. The man working there said they were marble but they're not - just different colored rocks sliced 1/4" thick. Small - the largest is maybe 1" x 3". The 'look' is just perfect and it would provide good traction. So I have two questions.... 1) Would pieces this small be a problem (because of all the grout lines)?? I assume I would need to seal it somehow - would that make it ok?? I'm not worried about laying it - I'm worried about it holding up. 2) Can anyone suggest a different source?? The stuff at the store is arranged on a netting and looks really nice - but also costs $27.00 a sq. ft. (yikes!!!). That's $500.00 just in tile for the shower floor!! I went to the big craft store and looked for 'river rock' (people use it as decoration or to put over the dirt in a flower pot so that cats won't dig in it. It's close but many of them are a bit too thick. But they are rounded and generally have at least one flat side. Any other suggestions as to where I could find something appropriate?? Any thoughts or suggestions would be much appreciated!!
