Hi, Don't be afraid of "jogging" the border around obstacles; I made mine follow the outline as best I could, and I think it looks authentic for my house's age. Casey

You need to post the existing layout and how this new space relates to it. This is not ideal. I do not think that you have design and build synchronized here. A good licensed and insured contractor knows his limitations. He should have contacts in the design world that he can refer a client to. Ask your contractor for a referral. Or find a K&B designer here on Houzz. You will need the measurements and diagrams of the whole space to get this planned out correctly. Please have the “what waterproofing system do you use for your showers” conversation with your contractor. Way to many people assume things will be done correctly, and all too often, they are not.

It's a beautiful tile, but I wonder about how you line up the ridges when two tiles meet in a corner. Is one side of your shower more visible - maybe use this tile on one wall only? I would probably put a seam right in the center of either wall, but a good tile installer should be consulted before you order. We used large width Porcelanosa tile with a dimensional wave pattern in our 5 ft powder room - but on one wall only, and we did the seam in the center.

What's the optimal size for a shower in an average master bath? Ideally 4' x 5' seems to be optimal. Mine is 44" x 5' and works great. And a related question -- how much glass surround is optimal? I noticed one of the posters on the 10ft shower thread commented that 3 walls of glass made things chillier. I believe I was the one who pointed this out but the problem wasn't that it was chillier. The problem is having to clean (squeegee) all that glass every single time you shower. Otherwise you'll be constantly seeing spots and soap scum on the shower. Yes Showerguard will help with spots and soap scum, but not 100%. The problem wasn't the glass. It was having 10'. Also I just played a bit with your plan again and here are my reasons: In the second bath, I moved the shower to the wall against the existing bedroom. This way you have more room in the actual bathroom for moving around. This also one day could be a handicap accessible bath if needed. Plus now every time you need to use the sink, you don't have to first close the bathroom door just to walk around the door. I moved the entry to your master further into the hallway. This creates a bit more of an "entrance" into your bedroom and actually makes your bedroom a bit larger because you don't now have the doorway taking up space in the bedroom. Plus now the doorway isn't practically hitting the closet door. I flipped the shower and tub and the entry and vanities. Why? So the bathroom door to the closets is closer. Then I moved the bed to the right wall and the dresser to between the closets. This is the exact same size, but notice how more spacious it feels? Plus now one person doesn't have to cram into the space between the night table and closet opening to get to their clothes. (And yes, ideally no one should need to walk around the bed to get to the bathroom, but in this case, I feel the much improved layout trumps having to walk slightly around the bed.
