I agree, the white trim is key in setting off almost any color palette. Nickle is en vogue now. In 30 years the next owner (or us if we rent it) will wonder how that was ever a thing.
Tiling is not difficult, but tedious. We have done enough of it now to know enough to get into trouble, and be willing to. These were the hardest I've laid because of the heated floor, large format tile, and the 3 step pattern I went with. I wanted it to at least look high end, even if the materials aren't what you would call luxurious. Though we did find a nice deal on that vanity with carrera marble. $600 and it's been in our garage for 2 years. Yep, 2 years. First thing we bought for the bathroom. I think out total spend including the few contractors we hired will be around $3000, maybe a tad more after all the nickle and dime crap is added.
For reference, here's what the room looked like when we moved in. Keep in mind, the house was built in '67.
We had done some minor cheap things like taking down wallpaper/painting, changing the laminate counter top, and fixtures but nothing major in this room. This whole house is different now, but fortunately it has appreciated enough and we did most our own work (even re-roofed it ourselves) so we'll still come out ahead should we choose to sell.
You can see I built a wall where those burglar bars were and added a frosted glass door. How was that fashionable??? Then got rid of the pocket door to make the room feel larger, and boy does it.
