Doors? Windows? Any existing plumbing, any DWV, in any of the walls, or stacked below? Any N/S/E/W orientation? Mongo

I like my first idea best as far as use of space. I know people say not to put toilets on an outside wall. We had one in our last house in Iowa, but we had 2X6 construction. I don't know how high your window is, but I'm guessing the toilet would fit under there. The shower would be 5 feet long or shorter if you want a wider space to get to the toilet. (kind of tight the way I have drawn). You could do a 5 and half foot long shower and do an angled door at the left end to allow room between the shower and toilet. The vanity would be about 7 feet long, unless you do a 60 inch vanity with a linen cabinet at the door. I would reverse entry door swing if you do that.. The second top right could work and you would still have a small closet. The bottom left plan would require waterproofing your front window. Hopefully someone will give you other ideas. The bottom right plan is bigger, but no closet. Each square equals 1 foot.

What you've done here is cut down a good-sized bathroom into two small, uncomfortable spaces -- with this much space, you shouldn't have to settle for minimal sized facilities, which is what happens when you chop it up into smaller rooms. As you've drawn it here, the toilet is in a scrunchy-small spot, and if you're going to have a shower-only in a master bath, it needs to be a showstopper of a shower -- not something reminiscent of summer camp. My thoughts: - Get rid of the two-room concept. - Simplify the layout. - This shower is 3-4' wide, making it large and luxurious. At 8' long, you could have a large bench and a second shower head for sit-down showers on the end near the bedroom ... or you could shorten it to 6' (still large) and use that space for a second, small closet opening into the bedroom. - Place the toilet behind a small pony wall. This will set it apart a bit without hampering the room with a wall /will let the room feel larger. Since you're so concerned about smells (which dissipate very quickly), you could keep a candle on the pony wall. - This gives you a 6-7' vanity for the sink, which will allow a single sink centered in the middle and a luxurious 24-30" drawer stack on each side, providing each spouse with ample at-the-sink storage. Don't fall for the idea of duplicate sinks, which would eliminate most of that drawer space and leave you with toothbrushes and razors living on the countertop. - Build in a low, shallow cabinet across from the toilet and sink. This will give you massive storage for towels, toiletries, etc. and display space on top.

I would think the most popular configuration would be what is typical for a house with three bedrooms. It would have a master bedroom with an ensuite of a nice size. A nice shower would be preferred by most people rather than a tub and small shower or a tub shower combination. The two guest bedrooms would share a bathroom and that bathroom would have a tub shower combination. I have always lived in dense urban areas (Manhattan and now Los Angeles high rise condo) and that would be the configuration for your target audience. Having three small master bathrooms would be a configuration if you were renting to three unrelated people who needed to share the rent and personally I don't think that is the optimum tenant as families and empty nesters are more reliable and probably long term versus constantly moving as young unrelated professionals would.
