I've had marble in my bathroom for ~4 years now. Not only was it a lot more expensive than budgeted because there's a lot more wastage while cutting the tile, but four years later, I am not sure if I would do it again. Of course the beauty of it is ethereal. We recently got porcelain tile in our kitchen that "looks like marble", but.....one month after installation, it's no marble, although it is very relaxing to walk on a surface that would forgive you for spilling wine, soy sauce, lemon juice, tomato ketchup and bunch of other things. Marble maintenance is painful. Even a bottle of toilet cleaner left on the tile will leave a permanent ring on the stone. So, my advice is this: try looking into alternatives. At the same time, if you must get marble in your bathroom, do your due diligence on how to keep it clean without etching it. A lot of cleaners will etch it. It's not a material I would choose for a bath other than Master bath where access is limited and people who use the space are careful.

Crap. And I had even done a test to make sure I knew how to do this. Sorry.

Just go shopping and look at things you might like. My towels are from Target and the tassel lamp is from a flea market, artwork from Stein Mart, candles from TJMaxx. Just take your time in finding things you like. I think the white tiles will look great with that color. You have far more light with white tiles than I had with the blue pearl granite. Go for it. Do almost everything in white and it will have a cozy spa look. Do you have a shower curtain? If not, look for one similar to a flame stitch or an ikat which would have several colors, including a cool color like your paint and maybe some fiery reds and do all the rest in white. Maybe add some red candles here and there.

O.K. so I said "luxury vinyl" no way ever. Used this in a small bathroom and love it. Many of the very upscale homes in this area are are using luxury vinyl in baths. This one has a super nice attached underlayment, a nice textured surface, and is so much warmer feeling than ceramic tile... you may be thinking more tile than plank... but thought I'd throw it out there :) Good luck on your decision! https://www.lowes.com/pd/SMARTCORE-Ultra-8-Piece-5-91-in-x-48-03-in-Blue-Ridge-Pine-Luxury-Locking-Vinyl-Plank-Flooring/1000196679
