Thanks, everyone! ogoopogo - One of the tile places actually showed me the schluter strips. The only picture I could find online is this one. I'm not crazy about the silver, but I thought it might look better with a matching color. What color is yours? Pipdog - So, is the cut edge of the inside of the niche covered by the front tile? I'm looking at a brick mosaic similar to the size of your kitchen backsplash, so I'm trying to figure out if that will work as well. It's a frosted glass, so it might look better than tile except I'm not sure about the smaller tiles. Catmom & dedtired - Does yours have bullnose?

With those formal shapes on the floor and shower walls I wouldn't go free form on the niches. I would do 1-inch square glass tiles with some subtle color that references the floor. Or maybe see if you could cut the floor tiles to somehow work in the niches. Follow the lead of your inspiration rooms - you've got stunning floor and wall tiles- let them star and don't give them too much competition. Otherwise it starts to look too busy IMHO. Edited to add another option would be a solid color tile if you could find one matching one of the colors in the floor and a complimentary shape to the shower and floor. Free form circles just doesn't do it for me in your setting.

Your insights @J D and @thinkdesignlive were invaluable last year. Before I jump in too deep, I'm curious if you consult on interior design / bathroom finish decisions. I'm not sure how to go about messaging privately. Here's the update: not much, other than me being a basket-case. We held off the whole project because of Covid and now are slated to begin our 2 bathroom project in January/February. I'm not sure if it was clear in previous posts, but there are 2 bathrooms at hand; the new one that's being added (let's call that one GREEN- it was the focus of the previous posts) as well as the existing one that will be completely gutted and redone (and let's call that one BLUE). I'll add BLUE's plans below--if you think I should start a new thread for it, please advise! OVERALL ISSUE: I don't have a vision for the finishes of either bathroom. I'm more settled on GREEN (see the "board and batten" post for inspiration and drawing--but we will not do a wall-hung toilet). The vision for BLUE is more ambiguous. So, I need to decide on: - tile: manufacturer, layout, etc - medicine cabinets (want a large mirror but a craftsman look) - wood vs white vanity (they will be custom- I'm leaning towards wood for GREEN and white for BLUE) - vanity top (which will be shower curb in GREEN and bathtub ledge in BLUE, too, right?) - faucets - lights/sconces - sink (maybe as easy as Kohler Caxton in both) Re TILE: I couldn't commit to Fireclay tile because I thought the minimum grout was too wide. I also heard a few concerning stories. I've recently requested samples from American Restoration Tile and will go look at Mission Tile West in person next week. I'm open to other manufactures, too. I know that: - we want a small hex floor in both baths; for the green bath this will extend into the shower - we want to have a color element (hence the "green" and "blue") in both baths - we will probably go with a 4x4" wall tile in both baths, though undecided - I love trim pieces but also am concerned about $$$ Houzzers, if you have advise on how to go about creating a vision, making decisions, what to prioritize (I know with supply chain issues, everything is a priority!), or something else, I welcome it. Thank you!! Here's the BLUE plan...not committed to the tile as shown:

@Trish Thanks so much! That is the brand my contractor wants to use. I had an old sample grout chart from 2017 so I ran to Menards and picked up another one in case there were newer colors. The Sterling sample on the new chart looks more beige, but on the one from 2017 it looks more like the grout in your picture. Crazy that the samples are so far off...most all of the colors on both samples look completely different. The K&B showroom had samples of Custom Building Products and we were thinking of using Ash, which is a light gray. We are doing the 2x2 of the same tile on the shower floor, but don't want too light of a grout color for there. And didn't know if we would want different color grout on walls and floor. Sterling might work for both (the gray one and not the beige one lol!). I definitely am going to do a mock up. Would be nice if they offered grout samples similar to those peel and stick paint samples. Those are a genius invention! Thanks again :)
