Estimated reading time: 6 minutes

I’ll show you how to build a master bathroom sliding barn door that looks nice and costs less than $200. I must add that I’m no “woodworker,” by any means but I do like to try. For me, these projects have been a nice way to relieve some stress during the pandemic.

So it started with an “I was thinking…” from my wife. When she says that it usually means I have to either:

  • move something
  • paint something
  • build something
  • or buy something

In this case, it was to build something. We live in a split level house and the bathrooms are tiny. Our master bath feels even smaller when the door is open because it opens into the bathroom. The solution to our situation was to replace a tradition door with a barn door.

Figuring out a Plan to Build a Slidng Barn Door for My Master Bathroom

I have never had to build a sliding barn door before. So I went to work figuring out how to do this, and I came across this video on YouTube. I based my door on the one in that video, but I modified mine by taking away the X pattern on the bottom half of the door.

Here is my list of materials I used for the barn door:

  • Six 1 x 8 boards (8 feet) – cut five pieces to 84 inches and three pieces to 29 ¼ inches
  • Two 1 x 4 boards (8 feet) – cut each to 84 inches long.
  • 1 box of 1 ¼ Trim head Screws (Why? – Smaller head, leaves easy to fill holes and less chance of splitting the wood).
  • Wood Glue
  • Wood Filler
  • Sanding Block (I used a random orbit sander as well).
  • Stain (I used Weathered Gray)
  • Poly-Urethane – I used oil based.

I bought all the lumber, screws, and wood glue at Home Depot for about $112. You will also need hardware (and a handle). I got mine on Amazon for about $66.

NOTE: Header Board. The barn door hardware is unlikely to line up with the studs on the wall, so I used another 1 x 6 board at 8 feet to cut to the length I wanted for my situation. I primed and painted this board the same color as the bedroom wall (some people stain it the same as the door) and attached it to the walls’ studs. This gave me a foundation to attach the door hardware.

(transparency: I am an Amazon Affiliate, but I bought these things before I joined that program. Regardless, that’s the first place I usually look anyway, as evidenced by the amount of cardboard I recycle each week).

Assemble the Sliding Barn Door

  1. Lay out all five longboards (1×8 cut to 84″) side by side lengthways.
  2. Attach the skinny longboards (1×4 cut to 84″) on top of each end board and flush with the edge using trim head screws (use wood glue on the underside).
  3. Next, lay the short 1×8 boards (cut to 29 ½”) across the top, middle, and bottom door. Attach with trim head screws (use wood glue on the underside).
  4. That’s it. Easy. You have just built a sliding barn door. You are going to have so much more space in a tiny master bathroom now. Hold on thought – you’re not done yet!

Prepping for color

  • The trim head screws will sink into the wood and leave a hole, so use the wood filler in these holes and other gaps in the wood. I used Minwax Stainable Wood Filler from Amazon for $11.
  • The door is now ready for sanding, and I used 80 grit on a random orbit sander. I finished with 150 grit sandpaper.
  • Now it is time to apply the stain. The stain I used was Weathered Gray by Varathane leftover from another project. When applying a stain like this, use a rag made from an old T-shirt.
  • Finally, I finished with 5 coats of oil-based PolyUrethane that I diluted down to 50/50 with mineral spirits. This allowed me to add a thin coat each time with a light hand sanding with 220 grit sandpaper between each dry coat (except the last coat).

  1. Hi there,

    Wow! I never thought that a Barn doo could be achievable at this amazing price? Did you get all the materials locally? This article has made me see how creative our minds can really be. With the materials at lower prices, we can actually hack-making stuff for ourselves. This informative article not only presents skills we can copy but also unlocks our minds potential. I tried carpentry some years back but I failed terribly. Now I can try these tricks have seen here and come out with the perfect project. I find this article the best and would definitely share it.

    Thank you for sharing,


    1. Thanks for the review. I’d wait a couple of months for the price of lumber to decrease. It’s way overpriced now with the pandemic due to not enough saw mills to make it.

  2. Love love love this information!  I am a DIY kind of gal and have been looking into getting a barn door for the master bathroom.  What has scared me away is the price.  I can easily make this.  And I like the idea of using a header board.  I have an old house and that was one thing I was worried about, was that the hardware would not line up with my studs.  I like the idea of staining the board the same color as the door.  I would have loved to see a final picture with your barn door up to see how it looks painted the same as the room.

  3. This is a very useful article. I’m very sure a lot of your readers would appreciate it. I personally do thank you in advance for this opportunity to guide me alll the way from A toz to build my Barn Sliding door for my master bedroom. I will find the time to work on it this summer. That would make both myself and my wife super happy. thank you for all the tips, the instructions, and your guidance.

  4. Hi, Stone!
    That’s a great idea that bathroom sliding barn door! As a DIY lover, I may consider getting one soon. Being able to decide the colour myself is also an added value when choosing to do it. Have you gone through a lot of trouble doing it? Is it easy to do it alone or should I get some help?!
    Thanks a lot for sharing and keep safe!

    1. I did it myself. It was my first time. I just followed it step by step. Having a place to stage it (like a garage) is great so you do a little bit at a time. I’m not a woodworker and I don’t have professional-grade tools. The off the rack lumber isn’t precision cut so I did use a bit of wood filler as well to fill in the gaps. You would need help lifting the finished door as it’ll be heavy and awkward. Also make sure to add the head board to the wall in the studs then you can hang the door on that instead of the wall itself.
