Try a light grey. I wouldn't go beige with the yellow. Dark wood looks great with grey walls. Yellows and brown also work well with grey. So pick a light grey and good luck.

Your best bet is to have a residential structural engineer do a site visit and a soil test. As the home is only 10 years old, it is normal to have some settlement and additional settlement after 10 years should be minor. The fact you are concerned of future settlement should be a red flag. Additionally, you are concerned about moisture. Two red flags. It is your choice, but buyer beware. Best of luck.

I have the same kind of bathroom and saw the same video. I used an angle grinder to remove one of the walls. You have to have hearing, breathing, and eye protection. I don't think there is any way to avoid the dust. I'm going to direct a fan to an open window in the bathroom. My sinks are top mount so there was no problem removing it. I replaced the faucet only for now. I also changed out the drain and stopper. The old one was rusted to the sink. I had to bang on it with my loader from my tractor with the sink upside down to get it off, lol. I have put off removing the rest of the wall and the cabinet because it is such an ordeal. You might check with Daltile to see if they still make the tile. Maybe try cutting away the cabinet while keeping the counterop supported and then dropping it so that the joint gets more exposed? I'll be interested to know if you get to this before me but I'm doing an entire gut job.
