I wonder if I should try and include this in a bathroom remodel that I'm doing right now. 90% of people in America have a day to day life where their surroundings look no better than this. If you really stop to analyze, most of our surroundings are pretty ugly.
So I wonder if painted/plastered walls with unique patterns will stick around, or if it is just a trend that will look bad in a couple years, and if I should attempt it. Looks a bit more challenging than regular painting. Maybe start with just an accent wall? back of a closet? it's going to be a very modern looking space, since I've got a wall hung toilet, lever door handles, vessel sink, thermostatic shower mixer, square recessed lights, matte black fixtures and hardware. shit that's pretty common in Europe but rare in America.
venetian plaster is beautiful looking, but as others have said, plaster work has become a bit of a lost art with the advent of drywall/mud.
however, years ago I was considering aesthetic choices for a multigenerational home I was mentally designing for a future and I was thinking of how I would want it to feel. and I stumbled across the YouTube world of faux finishes that can be achieved with modern primers, paint, and wax products and considerably less talent than is required for plaster work. I am now of the opinion that you really can make drywall look like anything using faux finish techniques.
but for a bathroom, I would probably go with floor to ceiling porcelain tile, large format for less grout. though I have heard of these like waterproof wall panel systems that are super easy to clean and can look like anything. like this https://fibosystemusa.com/
I want to be able to clean up the place easily using a pressure washer after having an explosive diarrhea attack during a backflip.
