Hey there, I’m thrilled to help you build a bathroom cabinet with doors! Let’s kick things off by measuring your space—trust me, I’ve messed up cuts before, and it’s a headache! Grab a tape measure and jot down the height, width, and depth of your spot; aim for a snug 30-inch wide by 24-inch high frame. Curious how to avoid my DIY blunders? Stick with me for the next steps!
Before You Start
Before diving into the fun of building a bathroom cabinet, let’s chat about what you need to do before you even pick up a hammer! Man, I’ve jumped in too soon before, and it’s a mess—trust me!
First, scope out your bathroom space. Measure the spot—width, height, depth (say, 24 inches wide by 30 inches tall)—so your cabinet fits like a glove! Double-check with a tape measure!
Next, consider plumbing or electrical lines. Don’t nick a pipe—yikes! Mark spots to avoid.
Lastly, plan your design. Sketch it out. Simple or fancy, make it yours!
What You Will Need
Hey there, let’s gear up for this bathroom cabinet project with all the right stuff! I’ve messed up before by forgetting tools, so don’t skip this list!
Here’s what you’ll need to avoid DIY disasters:
- Wood: Get plywood, ¾-inch thick, about 4×8 feet for sturdy sides.
- Screws: Grab 1.5-inch wood screws; they’re a lifesaver!
- Hinges: Pick two sets for the doors—trust me, cheap ones fail fast.
- Paint: Choose a water-resistant quart for bathroom vibes.

Stick with me, and we’ll build something awesome together! Wow, I’m pumped!
Step-by-Step Guide
Hey, let’s get started on building that bathroom cabinet together—I’m so excited to guide you through this! You’ll kick things off by measuring your cabinet space accurately, cutting wood panels precisely, assembling the frame securely, attaching door hinges with care, and installing shelves neatly. Man, I’ve messed up measurements before, so trust me, we’re gonna double-check everything—let’s do this right!
1. Measure Cabinet Space Accurately

Wow, let’s dive right into measuring your bathroom cabinet space with precision! I’ve messed up measurements before—ouch, talk about a tight squeeze! Let’s get this right together.
First, grab your tape measure and a notepad. Measure the height, width, and depth of the area where your cabinet will go. Write down every inch—trust me, guessing won’t work!
Next, double-check corners with a level; bathrooms can be sneaky with uneven walls! Note obstacles like pipes or outlets. Accuracy is key here—no wobbly cabinets on my watch! Let’s nail these numbers before moving forward, okay?
2. Cut Wood Panels Precisely

Alright, let’s tackle cutting those wood panels with razor-sharp precision! Man, I’ve botched a cut or two before—nothing funnier than mismatched edges, right? Stick with me, and you’ll nail this!
Gather Your Tools: Grab a circular saw (I love my DeWalt 7-1/4 inch!) and a measuring tape. Don’t forget safety goggles—trust me, sawdust in the eye stinks!
Mark and Cut: Measure your panels to fit the cabinet dimensions, like 24×18 inches for sides. Double-check, then cut slowly along penciled lines. Steady now! A wobbly hand ruins everything, and I’ve learned that the hard way!
3. Assemble Cabinet Frame Securely

Dive right into assembling that bathroom cabinet frame, because this is where the magic starts! I’ve messed up a few builds, trust me—just follow along. Let’s get this sturdy!
Gather Your Stuff: Grab your pre-cut panels (2 sides at 30”x15”, top/bottom at 20”x15”), wood glue, and 1.5” screws. Double-check measurements—ugh, I’ve cut wrong before!
Build the Box: Lay a side panel flat, apply glue, and align the top panel. Secure with screws using a drill. Repeat for bottom and other side. It’s like a puzzle, folks! Keep it square—use a carpenter’s square. Wow, it’s shaping up!
4. Attach Door Hinges Carefully

Get ready to tackle those door hinges, because this step can make or break your cabinet’s look! I’ve messed this up before—trust me, wobbly doors are a nightmare! Let’s nail it together.
First, grab your hinges—standard 35mm concealed ones work great. Measure 3 inches from the top and bottom of each door, marking spots with a pencil.
Now, drill pilot holes (1/8-inch bit) for screws. Attach hinges to the door securely—don’t rush! Then, align them with the cabinet frame, screw ‘em in tight, and test the swing. Look at that smooth motion! We’ve got this!
5. Install Cabinet Shelves Neatly

Three cheers for reaching the shelf stage of our bathroom cabinet project! I’m thrilled to see it coming together, and I bet you are too! Let’s get those shelves in neat and tidy.
First, measure your cabinet’s inside width—mine was 30 inches. Cut ¾-inch plywood to fit snugly; I goofed once and cut too short (ugh!).
Steps to Install Shelves:
- Mark shelf heights with a pencil—try 12 inches apart.
- Drill pilot holes for shelf brackets; use 1-inch screws.
- Secure brackets, then slide shelves in. Voilà! You’ve got storage, and no wobbly messes—trust me, I’ve been there!
6. Paint Cabinet Surface Evenly

Let’s switch gears from those neat shelves to giving our bathroom cabinet a slick, polished look with some paint! Man, I’m excited to see this come alive! A messy paint job’s a DIY disaster I’ve had before—let’s avoid that.
Start with a clean, sanded surface; grab 220-grit sandpaper for smoothness. Use a primer first—try Zinsser Bulls Eye 1-2-3 for great coverage. Then, apply your paint (I love Behr Semi-Gloss in Coastal Blue) with a 2-inch angled brush for edges and a mini-roller for flat areas. Go thin—two coats beat one thick, gloopy mess! Wow, it’s transforming already!
7. Mount, Secure Cabinet Hardware

After painting that cabinet to perfection, it’s time to tackle the hardware and make this beauty functional! I’m so excited to see it come together, and I bet you are too!
First, grab your hinges—standard 35mm concealed ones work great. Align them on the door edges, marking spots 2 inches from top and bottom. Drill pilot holes with a 1/8-inch bit to avoid splitting. Screw them in tight!
Next, attach knobs or pulls. Measure 2.5 inches from the door’s edge for placement. I’ve dropped screws before—ugh, so annoying! Secure them with a screwdriver, and you’re set!
8. Add Decorative Door Trim

Dive right into jazzing up your bathroom cabinet with some snazzy door trim! Man, I’ve botched this before, but let’s nail it together! First, grab your materials—I’m loving 1-inch wide, pre-cut wood trim from Home Depot.
Now, measure your cabinet doors. Mark 1/4-inch from each edge with a pencil for a sleek border. Cut trim at 45-degree angles using a miter saw (it’s just a fancy angled cutter) for perfect corners! Glue ‘em down with wood glue, clamp tight, and wait 2 hours.
Check it out—it’s gorgeous! Who knew we’d create such flair? Let’s celebrate our DIY win!
9. Seal Cabinet Edges Tightly

While we’re riding high on our door trim victory, it’s time to tackle sealing those cabinet edges to keep moisture out! Man, I’ve seen water ruin cabinets—let’s not let that be us!
Grab some silicone caulk (clear, waterproof, $5 at hardware stores). Cut the tube tip at a 45-degree angle for precision. Squeeze a thin bead along all exposed edges—about 1/8 inch thick.
Use your finger (wear gloves!) to smooth it out before it dries in 10 minutes. Wipe excess with a damp cloth. There! We’ve armored our cabinet against bathroom humidity—take that, moisture!
10. Test Door Functionality

Before we call this bathroom cabinet a wrap, let’s make sure those doors swing like they should! I’ve had doors stick before, and trust me, it’s a headache! So, let’s test ‘em now.
First, open each door slowly. Check if they glide on those 3-inch hinges or catch anywhere. Look for a smooth 90-degree swing!
Next, close ‘em tight. Hear that click? That’s the magnetic catch (1-inch strength) working! If they wobble, adjust the screws with a Phillips screwdriver.
Man, I once ignored this step and—yikes!—had a door fall off! Don’t skip this, okay?
