It won’t look cheap, but it is extremely expensive. We had decided to go that route and it was an additional 30k over and over above natural stone. We have now decided to go with large format porcelain tiles instead

Oh wow, ok I thought it was way cheaper to go with porcelain. Back to natural stone plan we go! We'll just call any water staining character and move on with our lives.

A couple of years ago, I tore out a natural stone shower floor due to staining and went with large format porcelain tiles and a linear drain. We did 12"X 12" rectified, porcelain tiles with minimal grout lines (3/32"), and epoxy grout, and haven't regretted it. No staining, clean looking, and affordable:

With a linear drain you could even go with larger tiles, like the 24"X24" ones we have on the rest of the bathroom floor.

kudzu9, that is GORGEOUS. I’d prefer it over any natural stone, any day of the week.

Thanks. The other thing nice about it is that, although the surface is semi-matte and smooth it is extremely non-slip. I feel like Spiderman when I am standing on it. ;-)
