When I was growing up my aunt and uncle had a house with "saloon" doors to the toilet area. We kids thought that was so cool.

It's interesting how much people are talking about the bending-down issue and front-loaders. A top-loading washer mostly eliminates the bending, and some of those can have a drier stacked above them (or come with one attached). Maybe the difference is that you're thinking of high capacity and I don't need that. But at least with driers since they're essentially all front-loaders, I think it's just about universal that people WANT it to be up higher and trouble arranging that together with the washer is the only reason they're not all up high like that. At the laundromat I go to, for example, there are two rows of driers, and the ones in the top row get used first. I'm planning for my new house but haven't built yet. There's room for a washer and drier side by side, but I'm thinking of a stacked unit anyway, not just to put the upper half of that space to use and turn the left or right half into free closet space, but also because it's easy that way to have the drier up high and eliminate bending with a top-load washer below. If I stick with separate drier and front-loading washer instead (to save money since the cheapest set is cheaper than a stacked combo), I think I'll build some kind of stage to put the drier up on, at least a few feet tall if not full washer height, just so it isn't on the floor. How flexible is machine location with a given set of pipe/vent connections behind them? Can the connections on the back wall of a closet/room that's wide enough for two machines be set up to accept side-by-side machines, stacked machines on the left, or stacked machines on the right equally well, or would the connections have to be set up for just one machine arrangement that's decided on ahead of time?

The closet in my master is 29 inches deep. Then I have 3 other closets upstairs like this in my sons' rooms and the guest rooms. Those closets are 22, 23, and 24 inches deep. I'm standing in front of them now and thinking that if I had shelves on the sides and a bar across connecting them....well, if they were jammed packed like I have some of these closets then it might be annoying trying to move past the hangers to reach the shelves. It depends on how much stuff is in there. Looking at it now, I think I have actual "dead space" above my bar. There is so much room between the shelf above the bar and the ceiling that if I was to change my closet right now I might just keep the bar across and add cubbies above the bar for my bulky sweaters. I really don't find reaching into the side space to be that annoying. I noticed in my husbands closet he has his suits in the side space. He only wears suits at weddings and funerals. He also keeps the ironing board in there. We don't iron often. Apparently I never do bc I just now learned that's where we keep it. Lol. I don't think that little bit of "wasted space" is worth such a huge overhaul. As long as it's lit well and the doors are good (I can't say enough how much of a difference it was going from sliders and bifold doors in my last house to doors that swing open). And we have good lighting in the closet which makes it easier to see all the way into the side space. For the record, I hang 90% of my clothes. I only fold sweaters and undergarments. So having just hanging bar isn't so bad for me.

I have a pocket door in my WC similar to your drawing, as well as both of my master closets. Swinging doors take up space, and both of my closets are out of view. Personally we leave our closet doors open 99% of the time, but shut them if we have guests over and will be giving a tour etc. As far as the WC toilet, I'm very happy with our decision to do the pocket door. My opinion is that it feels silly to shut/lock the main door to such a large bathroom, if we need to "use the toilet" we generally leave the main master bathroom door open for the "other half" to use sink/mirror/etc. It seems weird to me, once a master bathroom gets so large, to just have the toilet sitting out in the open so that's why I'm a fan of somewhat enclosing it for a little sense of privacy. Again, swinging doors take up space so IMO I'd never do that for a small WC. While the "mini room" does afford you some privacy, once in a while we do prefer to shut the pocket door. Maybe 20% of the time.
