And omg did not think about sanitary supplies!! Yeah, I get it. You don't think -- don't yet think -- of your little girls becoming women yet. Intellectually, you know they will, but that's not a thought that fits into your heart just yet. Says the mother of two girls, ages 20 and 23. Yes the closet is narrow! I’m nervous about giving up the bathroom space though. We do have a dresser also for the girls which I think will help. A dresser will give you more storage space, but the problem is that you won't have a walking aisle to reach the hanging clothing. Realistically, this is your space with a hanging rod and adult-sized clothing hanging -- note that you only have about the width of the hanger for walking space -- you'll have to walk sideways to get to the clothes on the far right: idea; try to put electrical outlets to charge toothbrushes if they will fit ...One large mirror over the vanity. Yes, put electrical outlets on both sides of the sink -- I personally wouldn't put them inside medicine cabinets; that'd mean the girls would have to leave the medicine cabinets open while using the hair dryer, etc. ... and that would take up space /block part of the mirror. Double-yes to a wide mirror. The girls will need more time for fixing their hair than they'll need using the sink. As far as under the cabinet, we decided not to over-customize the storage for blow dryer, etc (I've seen some pretty cool customized pull-outs, Yes, I agree. Don't lock yourself into one organization method. or the tub/shower combo, have the contractor install 4 corner shelves to hold all the shampoos, shaving stuff, etc. Corner shelves are less expensive to install than niches. If you want niches, that's fine too. They are just more expensive to install. If you do niches, put a wide one or a tall, divided one so that there is plenty of room for products. Very good advice. Whatever you choose -- corner shelves or niches -- put in more than you think they'll need. Make sure your storage is tall enough for the big pump-top shampoo bottles, and don't neglect a spot for soap. For me having towels in the bathroom itself means a lot of clothes left on the floor. I'll take the other side of that coin. I'd rather the kids dress /undress in the bathroom. Towels and clothes may end up on the bathroom floor, but I'd rather have them all on the floor in one place ... instead of strung out over the floors in the bathroom plus two bedrooms. What do you think about changing the pocket door to a regular door that swings into the wall opposite the toilet? To tell the truth, I'd lose that wall completely. You're talking about two sisters; they can share a plain bathroom. The wall makes the two rooms small, and at some point that pocket door will break (possibly in the closed position), and you'll have to get a handyman to come in and fix it, which might mean opening up the wall. Pocket doors are more finicky /easier to break than hinged doors, and children aren't great at being gentle with things. This bathroom is pretty small. I'd make it one room.

How deep will the cabinet be? You could have all drawers on the bottom, then a small countertop surface in the white quartz, then cabinets (a few inches shallower than drawers) above, hutch-style. You could put electrical in one of the hutch cabinets to plug in electric toothbrushes. We also have a hamper in ours, but I'm not sure how much depth you have. Here are some HOUZZ photos: This one is built-in, but this shows what I was saying about having a countertop area. I would put all drawers below instead of the cabinet and no glass. This one has a laundry tilt-out, but if there is room for laundry in the bedrooms, maybe drawers would be more helpful to you in the bathroom: This looks nice and functional with the drawers below; it's across from the vanity and by the window like in your bathroom. I would put a countertop and have the top cabinets a little shallower than the drawers, more hutch-style, if you have the depth for that. If you want an extra mirror, but also want the storage, you could put mirrors doors.

I agree with Cpartist"s layout and like moving the closet over as suggested by D M so that bedroom 3 has easier access to the bathroom. Do you have room to have the toilet face the tub and add a linen cabinet next to the toilet? How wide is the tub toilet area?

Only you know what is valuable to have on hand, for you. How could anyone here advise you as to that? It sounds intriguing to consider living with very little. I have had the experience of spending time in a small rented space that had only the essentials, and coming away from that time with a new understanding of how little we really need. Really, though, only you can make that decision and your priorities will probably make themselves clear as you experience living in your tiny house and as you define your lifestyle. Don't worry much on it. Things can always be rearranged, eliminated, or added as you see fit. It there is a hurricane of any magnitude coming your way you would be advised employ the "vehicle" part of your RV to get out of the way of the hurricane. It does make good sense for all of us to keep some emergency items ready to be picked up and taken no matter if you live in S Dakota or south Florida.
