our new build is incorporating a J&J for the kids also. Here's the space from our drawings I don't know how it translates to the space you have, but hopefully it helps. I wanted the kids to have the ability to go to the bathroom/brush their teeth/get ready if someone else was in the shower. Plus the privacy, etc. etc. We had the ability to accommodate two full baths, but found the extra cost to be unnecessary (it was a few thousand in extra plumbing, fixtures, materials). It also meant that each would be a smaller bathroom, versus a nice size J&J. I'm really happy with the decision so far!

My parents house is like that, but there’s a wall with a wide doorway into the area with the vanity, so it’s open but also easy to close off by just putting a curtain rail up. It’s also oriented to the room such that if you only use enough light at the vanity to wash your hands for a midnight potty run, it really isn’t enough to bother someone in the bed if you place the bed sensibly. Getting ready in the morning would be trickier if you needed to do makeup and so on so needed proper lighting, so that’s where a screen or a curtain would come in.

I guess a big part of why we picked that location for the water closet was because there was already a window in there (room would not be dark) and because there is enough adjacent wall for a pocket door to travel into. Also because the plumbing could not be heard if the toilet is flushed at night. It's not exactly set in stone though since this wall does not currently exist and we aren't married to any drawings we've come up with thus far. Relocating the washer and dryer is a long answer. When I put in the doorway to the master bedroom I made sure to buy a door big enough for the washer and dryer to fit through. They absolutely must move out of the garage. As-is the dryer vents through over 20' of flex duct with two 45 degree bends and a 90. The washer drain and water lines run underneath the floor of the dining room which was originally on a slab, but was raised up about 1' to provide a space to run them. Think of it as a small, completely inaccessible crawlspace. Because of the height the drain angle could not be set correctly and the water lines have also had issues before we bought the house. Also, any maintenance or repair requires destroying the dining room floor. Other exterior walls are all taken up by bedrooms and the living and family rooms. If I put them in the small closet immediately off the master bedroom I'm looking at a straight shot, 16' of vent through the crawlspace. It's a very tough problem to figure out... I'm including a sketch that shows where the other bathroom window is though. It makes relocating other things or using the area as non-bathroom space very difficult. This whole part of the house has been very hard to figure out how to make functional. We don't know what the previous owners were thinking when they designed the addition. I'm normally not a difficult person but trying to piece together a better layout has been very frustrating. edit: Tomorrow I will play with the layout a little more... there may be a way to move the W/D over towards the window to the right of the vanity. Not sure where I would put the water closet but we'll see... This post was edited by schicksal on Sat, Jan 3, 15 at 22:03

1.Have the bathroom entrance from closet? or keep them separate? Separate entrances are generally better, but the entrances right next to each other as indicated is the second best option. Saves walking through the wet bathroom unnecessarily, and waiting or disturbing the person using the bathroom to get to the closet. 2.General Bathroom layout - any better layouts? with current layout our vanity can't be more than 4ft, will it be small for this bathroom? If you're still planning, dimensions aren't fixed as with some renos. You can often shuffle things around if you need. The bathroom is decently sized, but not massive. Don't cram a 7ft shower into it, and waste valuable space. The layout below shows a 3'3"x4'7" shower, and leaves space for a 6' vanity Do let us know how this fits into the entire plan.
