Before I get deep in it with a build out of kitchen cabinetry, I decided to test myself with a vanity for our master bath. Before this we had a pedestal sink, which was fine except it had no storage, and we are into storage these days.
I ordered the sink from ebay. It was the right size and shape for what I wanted to build. The legs are from trusty Ikea. The faucet is Hansgrohe. I used the 3/4" birch plywood for the cabinet and doors.
It starts with a plan. It was all in my head until I had the sink and legs in hand, then I could sketch out exact measurements. It was nice leaving the computer out of this project. Sorry computer.

Once again, the courtyard becomes the workshop.

You can see where I'm going here with the pulls. Doors both get a 45º angle cut on the back side where they meet at the top. The panel above them gets one facing out that aligns with both the doors.

Put together. I drilled the holes for the legs before finishing it, so here's a leg test. Okay so far.

Then I dropped the sink in to make sure there wasn't a catastrophic mismeasurement. Still okay!

Now we finish. I've been working on replicating the look of aged lacquer on birch plywood. I've tried a few different things, tung oil, shellac, stains. Tung oil is okay, but seems to work better on solid woods where it can really soak in deeply. Shellac is nice, but a bit too orange. Stains have the same issue as tung oil, in that they just don't seem to penetrate or have enough effect. This time I used Minwax's Polyshades in Pecan, satin. My theory is that most of that warm amber glow on the vintage cabinetry I've seen in the neighborhood is the lacquer yellowing, not a stain or the color of the wood per say. This stuff actually has the color in the polyurethane, so the color sits on top of the wood. I like the way this took and will probably do the same thing again next time.

I used
these hinges. They're full-overlay, fully concealed and flush mount. They were easy to install and close nicely.

Installed! The plumbing only took 2 trips to the hardware store. They guy helping me said it would probably take 3.

Sink and faucet.

While I had the table saw out, I ripped a couple matching shelves.
