Okay. I'll start right off with the part that you (and others) probably won't like to hear, to get it off my chest and out of the way. :-) When I see a home that has the exact same cabinetry and granite in the bathrooms as in the kitchen, I don't really get a "custom" vibe off it. To MY eye, it is a rather more builder-y look, like the leftovers from the kitchen counters were used up in the bathrooms (the "well, we paid for the whole d@mn slab, use it up!" philosophy) and the bathroom cabinets were lumped into the same order as the kitchen. If you are passionate enough about those cabinets that you want them in the bathrooms, by all means use them, but think about a different stain and a different top; conversely, if your heart is really set on the granite, put it on top of a slightly different cabinet. When I read your post and saw your pictures, though, what popped into my head were Jim Canton's custom "rustic" and "country" (which still has your beadboard door insert and I'm sure stained parts could be matched to the kitchen if you wanted to do that, but I like the mix of painted and stained parts) vanities. Yes, they're expensive - perhaps think of those as inspiration if your budget does not stretch that far. I admit to being a bit of a ho for the unfitted look but if you have the space a pine pie safe type cabinet would be great for storage, stained to match the trim. Since you adore copper as much as I do, copper sinks are almost a no-brainer, and ditto for lighting. Look at Arroyo Craftsman's offerings. I just LOVE their Simplicity series which is so very versatile. I have the "raw copper" SB-1 sconces and hate how they're patinating, so I would recommend the antique copper instead. Clawfoot Supply has some pretty and reasonably-priced copper towel bars etc. (the Aztec line), and this nameless one from A-Ball Plumbing is quite nifty as well. I like how they're all subtly different instead of being really matchy-matchy. For the floors, I think a slate-look porcelain mosaic would look excellent and be very durable/easy to take care of. I myself like a rather scaled-down tile size for a smaller room, and it does provide better traction and believe it or not it's not that busy if the grout is kept to the same color value as the tile. If the bathroom floor were going to actually touch the real slate flooring I would go in a different direction, but since they're separated by carpet and you can't stand on one and see the other, I think you're OK. Both Daltile and AO have very convincing slate-look "suites" in which there's a 12x12 tile and a mosaic; I think it would look great in the tub surround to use the larger tiles as a field with a listello of the mosaic tiles (three rows, say) at about shoulder height. American Olean's "Highland Ridge" has a fabulous mosaic of 1x3 tiles along with 12x12s. Yes, it would darken the tub alcove but that's easily enough rectified with a couple of recessed lights (about the only use I really like the things for! LOL). I think you're a very smart person for eliminating the whole subway-tile schtick, but if the dark tile is just too much for you, I'd think about a 8x8 or 12x12 white tile trimmed out with a slate-look mosaic, as a broad listello and perhaps vertically at the border of the tile. I think the embossed copper you're using for kitchen backsplash would be perfect on the ceilings. Rather than being "in your face" they would be something that you catch out of the corner of your eye, and perhaps don't even register consciously but just add to the whole sense of warmth and charm as well as reflecting light downwards. Think about using the plastic version though - they look very good and you won't have any problem at all with corrosion. Aluminum "tins" won't rust but are much more expensive. If you have leftovers that you want to use up and you're working with steel, make sure to backprime them with a rust inhibitor.

My GC said 4-5 weeks, so my big dog and I moved into a friend's condo with her and her 2 cats. 2 weeks in, they were clearly nowhere close and they provided a schedule showing not done with the bathroom for 8 weeks! My sweet friend said no problem although the animals were driving us both crazy. Then we got to 6 weeks, it was pushed out more, and I said I need to get back in my house. At that point there was a tub with running water, and a toilet within a few days. Several times they had to remove the toilet for tiling or other work, so I used their porta potty outside, then eventually bought this camping toilet to use at night. I showered at the gym. My project included reframing most of the bathroom walls and relocating the fixtures, in conjunction with a kitchen remodel. Much more than simple bathroom remodel. If I did it over, I would have insisted on seeing their schedule before starting work. I think the GC gave me the initial estimate without actually crunching the numbers, and I think they could have done more to prioritize the bathroom completion first (as opposed to the kitchen work, which was lower priority).

Hire the right designer, and they will have contacts. Plan for next year, at double your budget.

We renovated recently and removed an old cast iron tub that had been reglazed badly several times - it was tough for our plumbing team to find someone to cut it up and get it down the narrow stairs.. we opted for an acrylic model for our replacement, I absolutely love old things too but definitely appreciate the new pipes that our team was able to run to the new bath as well as a nice level subfloor 😅
