Hi, I have the Linea (below). It is not installed yet. I choose it because it takes a standard rough-in circle, like a hinged door does. The one you show notches out the door. I wanted flexibility with the door so it could be used as a hinged door if ever that was needed. The Linea I've shown does not come with an end pull though, so I found a pull that Sugatsune sells that is a very close match. The Sugatsune end pull has no moving parts, you stick your finger in and hook the bar that is part of the frame. The Linea is brushed stainless steel. I wished it came in polished chrome.

could you leave the extra 34" wide section unshelved, and instead mount shelves or racks on the back of the door? http://www.containerstore.com/s/kitchen/pantry-organizers/door-wall-racks/123

Personally, I don’t see any problem with having a walk in closet off of master bath. In fact, I like the idea... super convenient. As long as it is within your area’s building code guidelines, I don’t see why it would be an issue, or why you would feel you need validation for this idea (?). People take entire rooms of their existing houses to convert to custom closets, and most folks don’t view that as being odd. I don’t view it as being odd either, btw; and even if I did view it as being odd, it wouldn’t really be my business - since it’s not my house. As far as ‘’making things easier‘’ for your husband goes, though - I hope these extra modifications do work the way you intend, and that he doesn't just forego the closet - and throw his stuff on the bathroom floor!

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.
