Standing in the master bathroom one evening last autumn, I found myself staring at the peeling laminate of our 1990s vanity while my wife mentioned the local contractor's quote for a custom replacement. The number he’d scribbled on the back of a business Module_root__BamsY had enough zeros to make me reconsider my life choices, and I had that familiar 'I could probably build that' itch, despite the ghost of my first lopsided bookshelf still haunting the corner of the guest room.

I’m an IT project manager by day, which means I spend most of my life managing dependencies and trying to explain to people why 'just one quick change' isn't actually quick. Woodworking, for me, is the physical version of a codebase. If you mess up the foundation, the UI—or in this case, the cabinet doors—will never align correctly. This vanity project was the biggest 'deployment' of my hobbyist career, and I knew I couldn't just wing it from a grainy YouTube video this time.
The Blueprint Phase: Why YouTube Wasn't Enough
Mapping out the garage workshop, I realized that a bathroom vanity isn't just a box; it’s a structural component that needs to hold a heavy stone sink, survive a humid environment, and accommodate plumbing that never seems to be where the diagram says it is. My usual method of sketching on a napkin wasn't going to cut it. I needed actual blueprints, not just a mental sketch of what a cabinet should look like.
I spent late October sifting through the massive library of TedsWoodworking. If you’ve never seen it, the sheer volume—about 16,000 plans—is intimidating at first. It’s like being handed a database with no index. But once I filtered for 'Bathroom,' I found a shaker-style vanity plan that matched the exact 21-inch depth we needed for the space. In the world of NKBA standards, that 21-inch depth is the gold standard for a reason; it leaves you enough room for the sink basin without eating up the entire bathroom floor.
I also checked out My Shed Plans, which has a solid library of 12,000 structures, but that’s really more for the 'build a house for your lawnmower' crowd. For indoor furniture that my wife actually has to look at every morning, the detail in the Ted’s plans felt more appropriate. I needed the grain-level detail that tells me exactly how much 3/4-inch plywood to buy so I don't end up making four trips to Home Depot in a single Saturday.
The Standalone Carcass Strategy: A Contrarian Approach
Most DIY guides tell you to build the vanity frame directly against the wall, especially if your floors are as uneven as mine. However, I’ve learned that building in place is a recipe for a sore back and a crooked cabinet. My 'project manager' brain insisted on a different approach: assemble the entire cabinet as a standalone carcass in the garage. This ensures the box is perfectly square before it ever touches the bathroom floor.
Building it as a standalone unit allows you to use your workbench (the only truly level surface in my life) to check your diagonals. If the carcass isn't square, your doors will never hang right, and you'll spend three weeks fiddling with hinges. I treated the vanity like a modular server rack—get it perfect in the lab, then 'rack and stack' it in the production environment. You can find more on getting things lined up in my guide on Essential Woodworking Tools for Beginners Starting a Garage Workshop.
The 36-Inch Standard
One thing the plans emphasized was the 'modern comfort height.' Older vanities were often 30 or 32 inches high, which is great if you’re a hobbit, but for a 44-year-old guy with a questionable lower back, 36 inches is the move. That 36-inch height includes the countertop, so the wooden cabinet itself needs to be calculated accordingly. The plans had this mapped out to the decimal, which saved me from having to do 'on-the-fly' math while my fingers were dangerously close to a table saw blade.
A Sub-Zero Morning in the Garage
One snowy Saturday morning in early March, the temperature in Minneapolis dropped well below zero. I had the space heater humming in the garage, and I remember the sharp, clean scent of freshly cut maple mixing with the dry heat of the garage space heater. It’s one of those sensory moments that makes you forget about the spreadsheets waiting for you on Monday. maple is a dream to work with, but it's unforgiving if your blade is dull.
I was moving along at a great clip until the inevitable 'user error' occurred. I spent twenty minutes looking for a pencil that was tucked behind my own ear. I had actually stopped the saw, searched under the workbench, and checked the pockets of my sawdust-covered apron twice before I caught my reflection in the window. It’s the woodworking equivalent of looking for your glasses while you’re wearing them, or searching for a bug in a line of code that you haven't actually written yet.
Once the pencil was recovered, the cut list from the TedsWoodworking guide saved me from a much more expensive error. I usually forget to account for the thickness of the 3/4-inch plywood when calculating the interior shelf width. If you just subtract the exterior width, you'll end up with a shelf that's 1.5 inches too long. The plan already had the math done for me. It’s like having a senior dev review your pull request before you merge to master.
Joinery and Assembly
For the face frame, I stuck with what works: pocket holes. I know the purists on the woodworking forums will cry about 'real' mortise and tenon joinery, but I’m a weekend warrior with a mortgage. Pocket hole joinery is the standard DIY method for attaching face frames to cabinet carcasses without visible screws, and it’s incredibly strong. If you’re new to this, check out these Easy Pocket Hole Joinery Tips for Better Woodworking Projects.
The beauty of the standalone carcass strategy really showed when it came time to finish the wood. I could rotate the entire unit to get the light right, ensuring the polyurethane didn't run or pool in the corners. Doing this inside a cramped bathroom would have been a nightmare of fumes and bad lighting. I used a high-tooth-count blade for the plywood cuts to prevent splintering, which is a tip I picked up after ruining a $90 sheet of oak ply on a previous project.
The Final Deployment
By the time just before summer rolled around, the vanity was ready for installation. Moving a solid maple carcass from the garage to the second floor is a two-man job, or in my case, a one-man-and-a-very-patient-wife job. Because I had built it square in the garage, shimming it to level on our sloping bathroom floor was actually straightforward. I just had to scribe the base to match the floor's 'character.'
Installing the final soft-close hinge and watching my wife actually move her toiletries into the cabinet was the ultimate win. It wasn't just a weekend project; it was the first time my IT project management skills and my sawdust hobby actually produced something professional. The cabinet doors closed with that satisfying, silent 'thump' that you only get when everything is aligned to the millimeter.
Observations from the Workbench
- Over-engineer the base: Bathrooms are wet. Use pressure-treated wood for the toe kick or at least seal the bottom of your cabinet excessively.
- Plan for the plumbing: I had to cut a notch in my beautiful interior shelf because I forgot the P-trap exists. The plans had a 'plumbing zone' marked, but I thought I knew better. I didn't.
- The 'Shed' Perspective: If you find you enjoy the 'big' builds like this, a library like My Shed Plans is great for outdoor storage, but for anything with a drawer slide, stick to dedicated furniture plans.
- Beyond the House: If you're looking to get even more hands-on with your property, something like the Self Sufficient Backyard can give you ideas for structures that go way beyond a simple vanity, though it's less about fine woodworking and more about utility.
Is It Worth Doing Yourself?
If you’re doing this to save money, you might be disappointed. By the time you buy the maple, the cabinet-grade plywood, the soft-close hardware, and the stone top, you’re probably close to the cost of a mid-range store-bought unit. But the store-bought units are usually made of particle board and hope. This thing is solid. It’s version 1.0, stable, and built to last longer than the house itself.
If you're tired of 'winging it' and want to build something that doesn't look like it was made in a middle school shop class, I highly recommend grabbing a set of professional plans. It takes the guesswork out of the math and lets you focus on the actual craft. You can check out the same library I used here: Explore the TedsWoodworking Plan Collection. Just remember to check behind your ear for that pencil before you start tearing the workshop apart.
