Eliminate all the wood base molding and have Corian or Fypon ones fabricated.

Thanks Sophie. What I ended up deciding, since I had to make a decision, is instead of drywall on the outer half walls, to use the US Marble that is a very pale beige with veins that will be on the vanity top which adjoins the shower unit. The interior shower walls and base are all US Marble in white. That way, the US Marble will look okay on the acrylic base, and give a seamless look to the vanity top that adjoins. The shower will then stand alone from top to bottom, making a center point as you enter this small bathroom. Again, thanks!!

Do t mix beiges andcwhites. If you do this, choose one single color.

Before the remodel, I had a cream cabinet on the white tile floor and next to the white shower base and it was good. In the new sink, with the pale beige, or cream vanity, I'm having a white undermount sink. The white will also be the toilet. I think it will be okay. The tile floor will carry color also in the beige family. I had the samples of everything laid out before ordering, and it looked harmonious. Kind of like something Joanna Gaines would do. The walls will be painted green, matching the current valance colors of cream, beige, green and a dark pink. The adjoining dressing room will have carpet in green. I think it will all work out! Thanks!
