With demolition!
Because Demo Day is the best day.
It can also be the worst.
My demolition plans included removing the rest of the flooring, the toilet, and vanity. I planned to makeover the bathroom vanity if I could get it out in one piece. The builder installed all of the sink cabinets in the house first and installed the plumbing in around them. When I removed the vanity in the powder room remodel I had to destroy the cabinet which wasn’t the plan.
Joy.
I cut holes for the plumbing in the cabinet with this exact Rockwell oscillating tool (after reading a lot of specs and reviews I chose the Rockwell because it is the only oscillating tool that can use bits and blades from any brand not just its own.) I was pretty stoked this DIY idea actually worked until my husband and I lifted the vanity up and over the plumbing to discover black mold on the wall and wood vanity.

Oh yes, my friends. We sang the Condo Blues.
