First, a bit of backstory . . . Ever since we installed carpet over the tile in our basement, the pocket door to the bathroom has been difficult to close. It really requires a good yank to overcome the friction underneath.
The door was an orangey-oak color, and didn’t really match anything in my newly remodeled bathroom. Instead of fixing it, I started thinking about building a barn door over the opening instead. Our style is more modern/industrial than rustic, so I wanted something that would fit our existing decor yet feel totally unique.
One day, I stumbled upon this amazing headboard by my friend Sheri at Hazel & Gold Designs, and knew the wood shim texture was exactly what I was looking for. At the same time, Artisan Hardware asked me to create a barn door that highlights their gorgeous hardware!
This post will show you how to build the door. You can find all the details on how to install barn door hardware here. Click on the video below to get a quick overview of the building process.
Materials Needed for DIY Barn Door
- 3/4″ plywood cut to the dimensions of your door opening plus trim around the edge.
- Mine is 37 1/4″ x 80″
- 3 – 1 x 6 boards
- Wood glue
- 1 1/4″ brad nails
- Brad nailer
- Combination square
- Wood veneer banding (optional)
- Wood stain
- I used Varathane’s Stain + Poly in Kona to save myself the step of applying polyurethane to all those shims!
Optional materials for wood shim texture:
How to Build a Sliding Barn Door
Cut Plywood to the Size of the Door Frame
Cut a sheet of 3/4″ plywood to the size of your door opening plus the trim. You want to cover the trim entirely when the barn door is closed. This both looks better and provides more of a sound barrier between rooms.
You can use a table saw or circular saw to cut the plywood to size. Check out my tutorial for how to make a circular saw jig to cut straight lines every time!
However, I can’t wrangle a full size sheet of plywood in my small workshop, so I prefer to have it cut for me at the store! If you’re concerned about getting the dimensions just right, ask for it to be cut slightly oversized, then trim it down at home for the perfect fit.
Choose Which Side Will Be the Front
If your plywood has one side that looks nicer than the other, choose which side you want to be on the front. More expensive grades of plywood will be clear on both sides, so you don’t have to choose!
Since I was covering up the entire front with wood shims, I used the nicer side on the back. If you plan to paint your door, you can use wood filler to hide any imperfections.
Cut the Trim Pieces
Cut long 1×6 pieces to match the vertical dimension of the DIY barn door and attach them to the plywood with 1 1/4″ brad nails. Measure the width between these two boards, and cut three 1 x 6 pieces to fit. Attach them to the top, bottom and center of the door to create the frame.
Apply Edge Banding (optional)
Paint or Stain the Barn Door
Paint or stain the entire barn door. If you’re adding the wood shim texture, this will prevent the plywood color from showing through the gaps. I used Varathane’s Kona Stain + Poly, to match the floating shelves I built on the opposite side of the room.
If you just want to keep this simple frame style, you’re done! Allow the stain and topcoat to dry, then follow my instructions for how to install barn door hardware next!
How to Create Wood Shim Texture
This part is for the crazy people like me that want a unique look that takes hours and hours to make! But it looks amazing and I get complements on it all.the.time. Almost as many complements as my TARDIS door! 😉
Prepare the Wood Shims
Check out each pack of wood shims before you put them in your shopping cart. I found a HUGE difference in quality between packs and between stores carrying the same brand! Search for ones that have a nice grain and sharp corners like the one on the left.
Knock off any splinters from the edges and give each shim a quick once-over with a sanding sponge. You want the shims as uniform as possible, so set aside any with knots or weird grain markings.
Decide on a Pattern
Lay out a row of wood shims along the width of the door to see how many will fit. I had about 1/4″ of space left, which gave me a little wiggle room when placing the shims. There are 19 in a row.
Decide on the pattern you want to create. I did two alternating rows, with the top panel shims pointing up and the bottom ones pointing down. Each shim overlaps with the one under it by 2 1/2″. But this creates a gap at the bottom or top of each row where a full shim won’t fit.
Use those irregular shims you weeded out earlier if you can salvage the top or bottom half. Cut twenty shims 5 1/2″ from the wide end and twenty shims 5″ from the narrow end. These pieces will keep the angle of the shims consistent at the beginning and end of each row.
Attach the Wood Shims to the Barn Door Panels
Getting the first few rows of shims down correctly makes the rest of the installation much smoother. It’s a lot easier to see it than explain it, so watch the video to get an idea of the process. For more details, keep reading!
Run a line of wood glue down the length of the panel. Place one 5″ cut shim with the wider end against the middle 1 x 6, and nail into place with a 5/8″ brad nail.
The second shim overlaps the first by 2 1/2″. I used my Kreg Multi-Mark to quickly measure the placement. Nail through both shims.
Continue adding shims. The final piece should fit perfectly at the bottom of the row.
Apply another line of wood glue. Place a full size shim next to the first row, but not quite touching. Nail in place on the wide end.
Keep the same 2 1/2″ overlap as before. The wide ends of this row should be halfway between the wide ends of the first row. If you use the square, the end of the ruler should line up roughly with the end of the shim in the first row.
At the end of this row, there’s not enough room for a full shim. Use the 5 1/2″ cut shims to continue the pattern and fill the space.
From here, it goes much faster! Use the combination square to line up the ends with the matching row.
The finished effect is so cool! It almost looks like dragon scales!
This is one project where you really want to invest in a nail gun like the Ryobi Airstrike. I can’t imagine doing this with a hammer and nails! It looks like a lot of work, but I finished attaching all the wood shims in a little over an hour.
Paint or Stain the Wood Shims
With all the wood shims attached, paint or stain them (or leave them natural for a two toned effect!) Use a brush to really get into all those cracks and gaps.
Once the front is dry, stand the door up on end and stain the back the same color.
Attach Barn Door Hardware and Hang
Ready to see it? The final look is so cool!
Notice how the door completely covers the existing trim around the opening. This closes up those gaps between the DIY sliding barn door and the wall, so there’s no peeking into an occupied bathroom!
I love the combination of rustic texture in both the door and the metal pull.
