I would probably pick a wall color that coordinated with both the flooring and the adjacent room as a starting point and then select a vanity color.

If you can't find a scheme that you like with the existing floor, Then I would replace the floor and pick the scheme to go with that.

I would not recommend doing chair rail or beadboard paper. The vanity is clearly contemporary and it will never look like anything else but a contemporary vanity and chair rail and bead board paper would be at odds with that. Save that detail for the real renovation when you can change the vanity.

Do you think a gray such as some in my example pics would go with this floor? It will go with the bedroom. I will also add hardware to the vanity and it may look a bit different with that. I could also router the edges or something.

Ok, so I can't help you with the color question (color vision deficit) but the floor sounds like the real problem here. I get that it's a waste of money to replace it if you're going to change the bath's footprint in the future. So, what about painting the floor? Sounds pretty out there, but if you're confident enough about you materials to paint a marble counter top, the floor wouldn't be much more of a risk! Paint might adhere better than the counter and it certainly wouldn't be subject to more scrubbing or water...

I don't think painting vinyl would work very well, the floor definitely gets more wear than our countertop, and the floor is textured to look like travertine - so I'm not up for that. But thanks for the creative idea!

I am certainly willing to let the gray idea go if no one thinks it will work with the floor, I can be flexible. With the coolness of the master bedroom (which I love and do not want to change) I don't know if it will really flow with warmer colors.

Changing the floor would actually not be that expensive if I used vinyl tiles in a different look, it's just that I recently completed a kitchen facelift and DH is not enthusiastic about another "project" disrupting us. Which replacing the floor - and therefore removing the toilet - would entail! I do want to do that in future but for now I think I just want to paint these boring walls and vanity that don't really go with the floor either.

Let's say you have to have this floor - what colors would you choose?

I wonder if you could try the faux granite. I used it in a kitchen and it's still holding up. Bought it at Overstock.com, but they also sell it on Ebay for less than the original Web site.

Here is a link that might be useful: faux granite

nosoccermom, I have considered it, I saw your posts about it and yours looks great! I ordered the samples though and none really looked good in my rooms. The colors that company has are too busy and/or dark for these bathrooms, especially with the existing floor.

However I did find some patterned vinyl contact papers I am considering - they have some other granite patterns and terrazzo and marble, too! Check these out:

Terrazzo

marble

brown marble

I just am having hard time envisioning an overall color scheme for some reason, I don't want to decide on the countertop without considering the floor and how the wall color will tie it together.

The gold/st. cecilia looks really good with a dark espresso vanity. Have you looked at these below, the ones with the white cabs? This vinyl is really way more thick/durable than simple contact paper, although I have to say that the marble looks really gorgeous.
Also wonder how the Rustoleum counter top stuff works. And, then there's always Tinan's option on concrete (search for 500.00 kitchen makeover at garden web).
if you google 'faux granite' you also find people who have painted their counters with really amazing results.

oops, didn't realize that you were the OP. No concrete? How about special faux paint treatment?

Paint either faux or a plain color is my most likely plan for the countertop. Concrete is messy and a lot of work it was goid for the kitchen since I had to cover the tile but for the bathrooms the countertops just need a color change.

Right now I am trying to figure a color scheme that works with the floor and adjacent bathroom. None of the busier granites whether faux paint or vinyl look good with this floor or give the quieter look I am going for... Expresso does not work with this floor I did it for the powder room which had wood look floors.

No one has any wall color suggestions at all? :(

Guess it's off to the paint store to grab handfuls of chips!

I personally think shades of soft gray with soft tan (both in a similar tone although different colors) would look nice for the walls and counter. Then you could do the dark gray you did in your other bath for the vanity. That would tie in with your floors, and give you a coordinated pallette.

mayberry, thanks - I am going to pick up lots of grays and possibly tan chips.

The vanity in the power room is actually expresso brown, maybe the colors are not coming across in the photo/monitor. That brown looks good with the wood floor in the powder room but I check it against the "travertine" floor and it looks awful - makes the floor look pink.

I like the taupe and white bathroom just below the turquoise and white one. I think that taupe color would work with your vinyl floor. Either silver or plain white wood knobs on the vanity, new white shower curtain, and white trim around the mirror. White towels. I would have to replace the light fixture too- but with something pretty cheap so that when you remodel you can choose a new fixture.

palimpsest, I am a bit confused by the use of beadboard - for example this bathroom is described as contemporary and features it...

It may not work in mine, but I don't know if it is contrary to "contemporary" and I do like contemporary baths as much as transitional.
