Our basement bathroom went without a vanity to entirely too long – just ask my wife… It was 100% my fault as I was burnt out on all things bathroom after the plumbing contractor fiasco that we had trying to get the new bath plumbed and house re-piped.
Enough time passed and I got back on the horse. After some internal debate and a couple of redesigns on paper, I ended up using an all-wood retail vanity box that I got a smoking deal on, then HIGHLY modifying it with structure, extra shelves, a pull-out top drawer, and granite top. I cut the granite and backsplash to fit and then drilled the holes for the waterfall facet and top-mount sink.
There was a tiny snafu with the drawer at the very end of the build, but I altered it a bit in the shop and if you don’t watch this video, you would never know that it wasn’t on purpose.
I think total cost for me to build and finish this was around $900, but that includes the base, additional material, paint, granite, sink and facet. Not bad at all for a “custom” fit, built-in, granite-topped vanity.
