The "regular" bath layout that jensbride posted first is very similar to what our DD & DS shared for years and worked very well. The door, however, was a pocket style and placed directly across from the toilet. This allowed the vanity to be scooted around the corner to take up the whole wall. It leaves the toilet close to the tub, but with lots of elbow room. Our kids just learned to keep the door partially closed when the bath wasn't in use due to the "view".

I would love to see your unconventional master bath!! Our plan started with a first-floor master bedroom /bath plus an extraordinarily poorly placed powder room. You noted above that you don't like cleaning bathrooms -- I'm with you on that. Since it's just me and my husband most of the time, I don't see the point in two toilets on the first floor ... so we moved the powder room next to the master bath and removed the toilet from the master bath. So we're planning the powder room to be adjacent from BOTH the master bedroom AND the main house ... and then we have the bathing facilities separate. Unlike toilets-shoved-in-closets, the powder room is 5' the short direction, so it's large enough for comfort, and I only have one toilet to clean on the first floor. I've removed the other parts of the house, so it looks kind of confusing ... you'll have to trust me that it fits in nicely with the rest of the house ... at the foot of the tub, that's a little ledge and a TV for my husband ... that's a linen tower to the left of the vanity ... that's the shower head floating in mid-air /obviously it'll be attached to the wall: I definitely see your point about two standard bathrooms being more economical, just trying to figure out for myself if I was thinking of doing something different for the sake of being different or if it would actual make life easier for my family! Walking yourself through various options is a good way to determine that. We personally are sold on the above bath layout because my husband likes to stay in the tub for hours at a time (he often "reserves" the tub before a, so we decided it makes sense to place the toilet close-but-separate. Also, what computer program are you using? :) HGTV Home and Landscape Platinum Suite. It's nothing special. I drew up your latest suggestion in this program. Concerns: - If you're trying to have kids share, you need a sink in the toilet closet. Otherwise, you still have a problem with the kid in the toilet closet coming out and having no sink available to him ... if you're going to do a toilet-in-a-closet, I'd put a small pedestal sink in there too. - You have a bottleneck in the sink area. If the kids are using this area at the same time, you're going to have people trying to squeeze past people at the sink. - I forgot the exact square footage and have already cleared it out of my computer program, but it was in the 130s ... so it's still bigger than two simple bathrooms and has water walls spread around. However, if the access is off a common hallway, having two baths right beside each other seems silly to me I think the two baths side-by-side appear silly because they're floating in mid-air. If we had a whole floorplan and could see one bedroom to the left of the back-to-back baths /two bedrooms to the right of the back-to-back baths, it'd look different. It'd look like the bathrooms each "belonged" to those bedrooms, though they're accessed through the hall. Mrs. Pete has some great ideas. keeping your water from the same source, but with two separate you'll definitely have an easier time selling. best of luck! I agree that most people would be attracted to two plain bathrooms rather than a "creative" layout. With resale in mind, here's a question: How long do you anticipate staying in this house? If you're going to move before the kids are teens, I'd say go with one simple bathroom. One bathroom would be enough for them until they start in with make-up /hair and shaving. I think that a girls bath and a boys bath might be nice - perhaps the girls bath has one sink and more storage / makeup area and a tub and the boys get 2 sinks and a shower unit, etc That'd work fine if the OP ends up with a nice even split of 2 girls and 2 boys ... but since half these children aren't even conceived yet, that's a guess.

Very interesting that you were told that 24” x 24” costs more to install... that’s because your tile guy doesn’t like to work with them. I’m putting the same size throughout my entire home and in the process I came across one that wanted considerably more to do 24” x 24” and would do 12” x 24” for way less... and then I found another who looked at more logical and the price was the same regardless of size. I really believe it comes down to the installer, I’m like you and want to see as little grout as possible I also am having mine installed on the diagonal as they will run throughout and in a 4’ hallway that will look much better than straight. You posted in March if you have yours in please show us photos...

So ensuite or en suite is very clearly a British term (with French origin) and used in NA more commonly in Canada. It doesn't mean that Americans don't know what it means but the only reason I do is because of the Canadian origin on much of HGTV. Well - ok - maybe from travel to Europe before that. Where I live it hasn't become a common term. The fact is that pools are more common in warmer climates. Doesn't mean they don't exist of course in Canada but was trying to make an educated guess - house has pool using a British/French term - I would go with Bahamas or Aus. And - are we calling Southern Idaho warm? Back to the original question - the 4th bedroom will never have a toilet? I am confused because in one line you say ensuite means all 3 parts but then you say just vanity and shower is on the table. In the US, it would be a little unusual which is generally not good for resale value. Many people get up in the middle of the night to use the toilet. Having to go into a public area to do that (the hall) is not ideal if they are modest. But if that is already done, then it would still be helpful to have the shower in the suite but it would add a little to the "unusual" nature. So from a resale point of view, I would keep things as normal as they can be. Now - are in you in AUS or are you Australian? Clarity is helpful. Because resale in AUS - no idea. There are probably parts of the US that unusual is no big deal. In my area, it is a big deal.
