Stop in for a cup of coffee

Bathroom project continues. I know, surprise, right? Just knocked down the high spots and cleand up a couple spots my caulk got out of control.. Ready for second mud coat after more coffee. Still trying to find a vanity. Everything I see is overprice crap. It's all MDF -:wtf:. And I have near exactly 36" alcove. Most don't work right in the space. They are almost all designed to be freestanding, so top of a 36" cabinet is 37". That includes alacart tops with sink. Not sure how I could cut down marble or granite. Even the man mad composite stuff.. I might just bury the edges in the drywall. Looking at old wood furniture on Marketplace, etc for something I could repurpose.
I just got a tech tip about sealing around bathtubs. Fill tub with water. This way sealant wont crack when its filled later.
