I would do a search here for the following terms: "marble on shower floors" "marble stains" "iron stains in marble" "marble not drying" If you do a bit of reading, the common result you will see, is that marble is not the best product to use for shower floors or walls. My master bath was all done with tile from Walker Zanger, but I used their porcelain and glass tiles for products that are durable and easy to clean. I am willing to squeegee the whole shower after I use it, but not something that my husband or kids would do, so products have to be chosen with all family members in mind. I am now doing 3 more bathrooms, but went with a competitor of WZ in my area, as they have many of the same product lines, but had better pricing.

Thanks for the help guys. We actually like the floor and want to stick with that color family/look. Also we are doing it ourselves so no tile installer and the budget is fairly limited as we are already replacing an exhaust fan and doing some plumbing work once we have the shower ripped open. Are you advocating away from the idea of a contrast between the shower wall and the floor? We though it would look nice to have them not be the exact same but we aren't totally sure.

Zaz and Beth, I finally have some samples on my floor to look at (from the Tile Shop) and that's helpful, but it's a pain in the b*** to figure out what samples to order and from whom to order them - and expensive too! I could probably order an equal number of interesting samples from Merola/Home Depot, not to mention the additional ideas you've both now given me, but at some point I need to stop. Even though I feel I've 'narrowed' my focus to something with blue and/or patterned-moroccan-style, there are still so many options and resources to look at. I do like all the additional examples you gave me, Beth. Is EliteTile considered a good quality resource? I have felt comfortable having a retail face to consult with (Tile Shop and Home Depot) but if you and Zaz and others with more experience feel it can be ok to order from a place like Wayfair and this brand of tile, then I feel more confident about that. Both Tile Shop and HD have nice options too, but I've been a bit frustrated that I haven't been able to see an actual sample of a large-size cobalt option .... and the nice on sale lantern blue one is beautiful. What a price, too!! Weirdly, as I look more closely at the Wayfair/EliteTile Moroccan tiles, I'm seeing several that are the exact same patterns that Merola/HomeDepot offer. Do either of you know anything about this? I'd kind of like to add pictures of the samples I have from Tile Shop to see what you both think, but it might need to wait until tomorrow since this day is over and I'm beat. (Also, have other things in addition to tile shopping which I'm sure you both can relate to.) I am grateful to have both of you to converse with on this. Feel more comfortable.

If you retile the floor, it enables you to increase your Zillow listing value - under the category of last year remodel. Yes, you could leave it and allow the new homeowner to do the work themselves, but with so many wanting "move-in ready" ..... (And....Let's face it, most younger homebuyers were at soccer practice or playing video games, rather than helping with yard work or car/ home repairs. So, they know nothing about "how to" around the house,). New Tile Color-. I'd pick a light/-medium gray tone in the countertop. Black will show lots of dust, White might be hard to match to your cabinet color. Perhaps the one closest to the tub? It hard to tell the color for certain. What at color is the bathroom wall? If white, then paint trim to match gray floor.
