The guy that did my bathroom tub/shower surround will only use Wedi which is water PROOF not just water resistant It is the only thing he will use. Here is a link that might be useful: Wedi

Thanks for the pictures. I went over to the place that does the fabrication yesterday to check things out. They had quite a few displays for us to see and the one of the cultured granite looked very much like the one posted by Ashlander. Thanks. I like the darker color of the cultured granite walls, but am leaning back toward the cultured marble at the moment. I was really surprised that all of the marble ones are so, so white or bisque or the ivory. But, hey, I guess after all the 60s and 70s colors, this is better. I have a perfectly fine 76-77 inch marble top in hall bath with a blue marble color. I love blue, but it is such a dated color. The commode and tub kit are all in this color. It is going soon!!!! My vanity countertop in the master bath is much more neutral. It is probably the harvest gold swirls in the marble, but it actually looks like a nice tan or something along those lines. It is still okay, except that one of the sinks is beginning to pick up the surface cracks a little. It is the sink that we use the most. Also the sinks are in the shell shape and are so, so shallow. Oh yeah, the tub kit and the commode are in harvest gold. (YUCK---I remember having harvest gold fridge, stove, washer and dryer and thinking they were the greatest at the time! We are about to totally redo both baths. Anyway, I am leaning toward the cultured marble and am going to have them add more of the color dust that I want. They explained how they make this and the very small amount of the color dust that is added to the vat. I asked about doubling that or more. I was told that doubling the color would dramically change the swirls and make the color show more. So, I think I will go that way. In the master bath, we are adding a Jetta tub and since I love pink and mauve and don't particulary care for white, I am ordering it is the Innocent Blush color. It is not a pink, but I think a very nice NONE WHITE, non bique or non ivory. I will use the cultured marble called pearl and mauve. They will add double the amount of mauve dust. This will still be a subtle amount of color. In the other bathroom the shower will be the pearl and champaigne color--again with double the color. I can't make up my mind about a shower door, so I think I am going without one at first. I can always add it. We really won't use the shower that much and I think I will add a curtain at the moment. My neice owns a glass company, so I can have them do it later. I have to make a decision soon, so we can get this underway. THanks for the photos.

I installed my solid surface shower walls over drywall, not even greenboard, and put the custom solid surface pan over the wood subfloor. If you leave an 1/8" between wall corners and pump them full of color matched silicone, it allows for panel movement without leaking. Another of the advantages of solid surface in the shower, besides lack of grout to maintain, is the labor and material savings of waterproofing. Plus the foolproofery.

You’ll need to know where the studs are behind the panels and locate the the prefabricated niche between them. Look at the onyx site. They make them.
