Opinions on your questions: 1. Pocket vs. swing door: I'm not a big fan of pocket doors on bathrooms because they're more of a pain to close and lock. If you close and lock bathroom doors in your house. :-) 2. Benches are not mandatory. I prefer niches for storing shampoo and soap. Benches are usually to put your leg on when shaving. If you do have one in that corner, I'd recommend a triangular shaped one instead of square. There are pre-fab, ready-to-tile benches like this: I think the shower controls are fine where you drew them, on the bottom wall. Other thoughts: 4. code says toilet back to front should be 5' clear. Can you bump the wall a few inches to attain that? 5. I'd hinge the shower door on the other side. That will allow a towel rack on the bottom wall. You can easily fit a 48" vanity in that space. I'd definitely do it. On design, the typical "period appropriate" materials would be subway tiles in the shower and hex tiles on the floor. You could use natural marble on the floor if you wanted to splurge. I used larger hex porcelain in a powder room (not technically "period" but "in the style of"): With a neutral white/gray in the permanent stuff, you could pick your favorite splash of color for the walls. Or use that dark gray that's greenish, and use accessories, towels, etc. for the color. Your dining room is to die for, btw. Great work!

I'll get this started, hopefully others see it with some great suggestions. :) Green. Sage, celedon, forest. There's also a splotch of what looks like grey-blue at the top near the center so I think you could pull off a medium neutral grey. Or white walls would work. White Dove has grey undertones and is a nice go-to. Of course the paint colour will be driven by the other features of the room too: lighting, furniture, floor, wood tones... Really, art can be completely ignored when you're choosing paint, if the art is a beloved piece such as this one. It will fit no matter what because it is authentically You. ETA: oops, cpartist got it started while I typed. Neat to see we had the same ideas :)

I'm in love with your space! Had a similar look in the master bedroom of our previous home, which was converted from attic space in the mid-1940s, with wood flooring and wide wood planks on the walls, much like yours. It also had those wonderful built-ins/bump-outs. I miss that space. I'd go with earthy tones cooled with natural greens and warmed by muted reds and burgundies. This is a room that was meant to wrap you up in a hug and keep you cozy.

it's a mixture of lava rock and another type of rock. I'd be more of a fan if it was really tall (and I lived in the mountains) Or, was this cool dark color. (the copper hood and wood slat bench make the space) BTW, you could easily make it look like this. Romabio Masonry lime tinted a brown/black, and a very dark mortar for the joints. (which you could also 'paint') I still like the mortar wash option But, if you want to keep it as is, here's how to spruce up the stone. (Because right now, it's just not nice looking) Clean it w/a good stone cleaner. redo the mortar joints (repipe it ) and then apply an enhancing sealer to the stone. you should get pretty close to this look Looks better w/the appropriate lighting and the wood ceiling. The rock itself isn't anything to leave earth for. it's not some iconic mid century design. It's just something done in the 60's. if you like it great. But if you want to pay homage to more of a mid century look, there are better options. Do a roman brick like mentioned above, or even a glazed brick If it was mine, I'd do something darker like this (stacked brick) Bring in the right design, and this is gorgeous. more of a modern look w/3D tiles and black surround try a basalt or slate tile (I think the darker ones look so much nicer than lava rock) redoing it w/something a bit more linear: And, if you remove the stone, you can restyle it anyway you want. Here are the thinner bricks in a matte black w/a vertical paneling above the natural wood mantle. imagine it w/o your popcorn and the eyeball light and vertical blinds! so much better
