If your little one is struggling to reach the sink to brush their teeth or wash their hands, a small step stool can make a big difference. Buying one is easy, but building your own adds a personal touch—and it’s a fun weekend project you can actually finish. With just a few basic tools, some sturdy wood, and a bit of time, you can make a stool that’s safe, strong, and perfectly sized for your child.
What You’ll Need
-
1 piece of 1×12 board, about 3 feet long (pine or oak works great)
-
Screws (1¼-inch wood screws are ideal)
-
Wood glue
-
Sandpaper (medium and fine grit)
-
Paint or stain (optional)
-
Drill and screwdriver
-
Saw (a circular saw or hand saw will do)
-
Measuring tape and pencil
Step 1: Cut Your Pieces
You’ll need three main pieces:
-
Top step: 16 inches long
-
Bottom step: 14 inches long
-
Two sides: 10 inches tall each
If you want the stool to have two levels, you can cut another smaller board for the second step, about 6 inches shorter than the top. Make sure all cuts are even and smooth.
Step 2: Sand Everything Smooth
Kids will use this barefoot, so don’t skip sanding. Start with medium grit to knock down any rough edges, then switch to fine grit to get a nice smooth finish. Round off the corners a bit—it looks nicer and keeps little toes safe.
Step 3: Assemble the Base
Stand the two side pieces upright and attach the bottom step between them using wood glue and screws. Make sure it’s level. This is the foundation, so keep it square and sturdy.
Step 4: Add the Top Step
Once the base feels solid, place the top step across the sides and secure it with glue and screws. Check that everything sits evenly and doesn’t wobble.
Step 5: Finishing Touches
Give it one last sanding and wipe it clean. Then you can paint it in your child’s favorite color, add their name with stencils, or just leave it natural with a clear coat for a simple wood look. Let it dry completely before use.
Step 6: Test It Out
Set it in the bathroom and let your kid try it. Make sure it doesn’t rock or slide—if it does, you can add small rubber grips underneath. Once it’s stable, you’ve got a handmade stool that’ll help them stand tall and proud every morning.
Building a bathroom step stool for your child isn’t just a quick woodworking job—it’s a small act of independence. You’re giving them a safe, sturdy boost to do things on their own, and that confidence goes a long way. Plus, every time they climb up, they’ll be standing on something you built with care.
