I can't read the dimensions on this, so you'd have to sketch it out to see how the inches end up being allocated. I'd plan on bathroom fights. The kids are pretty close in age. I'd try moving things around a bit and see how it works out. Take the closet in the middle bedroom off that wall (we'll deal with it later). Put the toilet across from the tub with a small linen closet, maybe some hampers. Consider a sliding door (maybe frosted glass for light) between the sink are and tub area, which allows for two people to use it at once. Add a second sink area where the toilet was. Then take out the master toilet. Slide the closet over. Put the middle bedroom closet to the right of the new master closet location. Put the shower along the outer wall with the toilet next to it. Put a larger double vanity on the back of the closet wall. The vanity depicted looks a bit small for two people/sinks, but I can't read the size so hard to tell. Might have to make the closet a few inches shallower, hard to tell. If it were my home, the kids bath access issue and larger master vanity would be my "wants". Worth playing around on paper a bit, even if it just convinces you it isn't the right choice.

I am so sorry, I posted my post before I saw Angela and Memo's follow up! Angela and Memo, thank you SO much for such a detailed answers. Angela, I am definitely going to make the fridge even with the counter, I can easily lose that space in the pantry, that is the best idea in the world and I never in a million years would have thought to do that on my own. Right now I have a 30" wide fridge, which is next to new (stainless, freezer bottom) but it is not as wide as many I see as my current 45 year old house couldn't accommodate any bigger. I am wondering, I guess I should plan for a 36" deep space because in the future, I will want a bigger fridge, I do know that. I will have to make my fridge area extra large and have a smaller fridge for the moment (but this fridge could last 15 years!!). I'll try and figure that out. Re: stacking washer dryers - I am actually making 2 laundry areas - one in the garage for business (see previous post) and the other on the second level (see below my second level floor plans - original and changed). I will think about the stacking though at either location. But having a laundry and utility sink in the garage kind of solves memo's thoughts about muddy kids. In a pinch I could have them strip down there and keep some extra clothes in that room. Memo, my region is really not a farming area at all. There are no farms around for at least 30 min away, and even then only a couple of high end "heirloom variety and herb" crop farms. We are in the mountains, no room for farms! There may be hobby farms, but the community is not really a farming community. It's more of a tourist village, it's a skiing community in the winter. In the summer, there are lakes all around. Not saying kids won't find messes in the country, oh they will! But my garage laundry and sink should take care of that in a pinch. I am still debating your garage mud room though! Angela, I will def. think about a pocket door for the mud area, but I don't think company (except my kid's friends) will come through the back (garage) way. And that's why I want the bathroom out of the mud room, to keep people out as much as possible! Angela, I really like your idea about reducing the pantry size to accommodate a closet or storage area of some sort on the north wall of the pantry. Thank you for that. I had a feeling the pantry was a bit spacious, but I just thought it's be a great place to put things like a vaccuum, brooms etc in the middle. But that does make getting to the pantry items more difficult. I think your plan is more efficient. Re: Garage space. I reduced it to 2 bay partially because of the laundry room, but also I NEED to have an exterior pedestrian door enter on the same east side as the garage doors. They left NO room in the plan for an exterior door on that side! I can't put an exterior door facing the front house side, looks bad and confuses people as to which door to enter (hate that). I can't do it on the south (backyard) wall either as that is just too far to walk to the back and then walk back across the whole garage again to enter the house, crazy. Plus snow may be there in the winter. So hence, 2 bays + a pedestrian 3 ft entrance door. I know they sell garage doors with a entry door in them, and I may look at that option for the single 3rd bay, but since I am "ruining" the 3 car garage anyway with laundry and workshop/storage, I just thought I'd eliminate the garage door as well. Our ATV can scoot in there from the the 2 door garage. Plus, a 3 bay is not common in my area, just 2 bays or even one bay. The development where we are moving to (42 homes) is pretty diverse and we all have our own builders, people have different styles - no cookie cutter homes here. RE: Double pocket doors with glass for the office. I have a single pocket door with glass that is SUPER HEAVY to push open and closed. I struggle to open it, and it was a new high quality track. I think it is the sheer weight of the pine door and the glass. I don't know if that is typical, but I just wanted to avoid all of that by having regular swing doors. If I can be reassured that there is a way to do this without that heavy pull, I would be into it. I know they sell frosted fake glass (I have that too) that is lighter, but the look is very fake and light doesn't seem to come through it normally. I am open to suggestions. I was also "thinking" of installing glass on either side of the french doors for an even more open look, and I couldn't do that with a pocket door. I am going to work through that idea about using that space by the stairs where the window is to add to the bathroom, great idea again, I will draw it out. I hate loosing that window though, I like windows everywhere! I don't think I want to add a door on the sunroom side though, I personally don't like jack and jill bathrooms and I really plan the sunroom to be a very occasional use bedroom if at all on the main level as I already will have a guest bedroom upstairs. It's really just more to have a full bath on the main level. Love the idea of the ??? as a linen nook!! Problem solved! Or I tuck linens in the foyer closet in a tupperware bin and make a nice niche out of the ???. I really want this to be an occasional use "emergency" full bathroom... But time will tell, you never know about things until you really live in a house. Here is my second floor plan and the original. I will try and darken it in the next day or so.

The tile is a killer since there is so much of it, and it certainly does make a statement. I'm guessing you're leaning towards a bit more traditional? So at a minimum? A low-budget "fix"? 1) I'd get rid of any stained surfaces (door/trim) and instead paint. 2) I'd replace the three mirrors with rectangular-shaped framed mirrors. and replace the light bars above the mirrors with sconces. 3) You can just replace the vanity as a whole. If that's too much, at a minimum I'd replace the vanity faucet. If you can go beyond that, I'd replace the hexagonal sink with a rectangular sink. If you can still go further, I'd consider replacing the vanity top too. I'd reface the vanity with drawers with frame and panel drawer/door fronts that more resemble the traditional 6-panel doors.All that', it's probably easier to just replace the vanity as a whole. 4) You can degloss and paint the shower frames to get rid of the brassy color. 4a) The brass and glass surround on the back tub could be removed and replaced with a curtain. 5) I'd consider covering the existing glass with a topical frosted film. Not sure if the existing design will shadow through the film. But look at different films, their levels of opacity, and see it it'll work. 6) New towel bars, etc, to get rid of the brass. 7) A large throw rug on the floor in front of the two pedestal sinks might disguise the stepped floor tile pattern. Good luck!
