If I have the window in the shower, would I still be able to open it? I understand that it would have to be tempered glass but not familiar with other rules. I love this window - beautiful sunshine in the morning, view of the neighbour's gorgeous backyard and of course, fresh air.

@Josie23 Thanks for pointing that out. I forgot to put a sink in the powder room but of course it will have a sink. I was mainly focusing on the master area. The powder room will be about 7.5 feet long x 3.5 feet wide which should be plenty of room for both a toilet and a sink. I read that the minimum area for a powder room is 11 square feet but this will be much larger than that. I have seen some pretty small powder rooms for sure.

Here are some ideas. I know you didn't ask about this, but my sister had a cat-walk like you do that was open to the living room below. They built a floor and created a gameroom/bonus space. It was the least complicated thing they did to their house because they were also doing kitchens and bathrooms. The only little complication was that they had to raise the windows because they would have been far too low if they left them alone. It was a great improvement because of the bonus space, but it also made the living room below much more cozy and intimate. They were able to get rid of the 2-story hanging ceiling fan and install a beautiful light fixture instead in the living room. People actually use the living room more now than they used to. They didn't put doors on their bonus space but you certainly could. If you eliminate the lowest left-hand window in bedroom, you can install 30" custom closets that are reach in above and drawers below. If you get rid of the fireplace, you have more layout options. I put the long-hanging closet in the space where the bumpout and window are. It's true that windows in closets are not ideal bc the sun will ruin your clothes, but you could put a black-out blind on it. I put 2 options in this drawing, but it's such a large bathroom, you have a several viable options. I drew 2 that keep the toilet and shower plumbing in place. One of the options I drew would require moving the tub plumbing. Your bathroom is so large, you could have a linen/laundry cabinet in there in addition to tub, shower, vanity and toilet room. I love my linen and pull-out laundry. It's styled like a dining room hutch with a piece of countertop material and with the top portion stepped-back like a hutch would be. My cabinet builder made the pull-out laundry side look like drawers, to create symmetry, but they are fake drawers. I'm not a pro, so I'm sure others on here who are real pros will come up with better ideas.

The tile and hardware is the only thing I’d change. The vanity is very nice. And the countertops aren’t bad. Wait until you can do the tile. This space looks nice as is.
