Here is a little information on the K-304
Can someone please help me with the installation of a Kohler mistos shower/bath unit? I now have the drywall installed and stressing that I do not have it installed correctly. My next step would be installing the tile.
I am using a Kohler Mistos K-R37028-4-CP:
I tried to install the faucet deeper in the wall but the wall seemed pretty shallow. It was the deepest I could install it and still fasten down the pipes.
The distance from the center of the copper water pipe to the edge of the drywall is 2-5/8. The distance from the center of the pipe to the outside edge of the plastic frame is 2-3/4. The outside edge of the plastic is sticking out from the wall by 1/8th.
Am I in trouble? I was thinking of cutting back the plastic ring by 1/2inch, then putting the tile on closer to the center. Any advice would be greatly appreciated. Thanks. Trevor.

The green stuff is a water proof sealer I painted on.
That looks like a similar setup. Do you think mine is installed correctly? Is the unit sticking out too far from the drywall? Will the handle mount correctly once the tiles have been installed?
If your tile is fairly thick, you should be okay.
2-3/4" (70 mm) Thin Wall
3-1/2" (89 mm) Thick Wall
If over 3-1/2" (89 mm) and
up to 4-1/4" (108 mm),
use Deep Roughing-in kit
From center of pipe.
Is this what you have. You have 3/4" to work with there.
The coverage on your waterproofing looks thin. Did you use a mil guage when installing.
Drywall is not allowed in B.C. showers - what ever colour it is , blue, pink, green or white.
If you are using it because you are trying to save money at the very least apply the proper coverage of that liquid membrane you use. I have never seen that colour of a product before.

From your picture, it looks like the tile will be flush with the surface of the plastic "plaster ground", which is where it should be.

I have used Densshield behind the shower. It was muded with a concrete mixture. I have used one coat of Waterproof latex compound. I still need to apply another coat:
