How to Build a DIY Modern Sliding Door

Much like barn wood walls (remember this one??), sliding doors are so in right now.  They’ve been in for a while, actually.  I made my first set of DIY sliding doors over two years ago!  But I’m not sure they’re going to go away any time soon.

.

Not only do sliding doors LOOK nice, but they also save space and could save you a lot of money if you need to replace an odd shaped door that they don’t make standard anymore.  They are a fairly easy DIY project and the possibilities are endless when it comes to style and size.

.

You can make them solid wood with a farmhouse style barn door like these.  Or you can make them more of a traditional look with some frosted glass like these.  But, lately, I’m digging modern and mid-century style, so this time, I made one like this...

A friend of mine also loves the mid-century modern look and needed a space saving door for her newly remodeled bathroom. PS remember this floating vanity?? That’s this same bathroom!

.

Don’t you love this slatted glass panel door??  I do! It reminds me of those southern California mid century houses.

.

If you’re ready to make one of your own, I’ve got the how to for you right here 🙂

Step 1: Cut Pieces for DIY Modern Sliding Door Frame

Measure your door opening. If your door opening is trimmed, include the trim in your measurement.  Now, add 2″ to the WIDTH of your door.  You can add to the height if you want but don’t have to.  Now you have the size you need your door to be.  Cut 4 pieces of 1×4 the length of the height you want your door.

.

Now, subtract 7″ from the total width you want your door to be and cut 12 pieces of 1×6 this length.  Shown below is half of the cuts…two 1x4s and six 1x6s.  This will make one frame, but you will need two.

Step 2: Assemble the DIY Modern Sliding Door Frame

Drill 3/4″ pocket holes in both ends of all the 1×6 boards.

Using 1 1/4″ pocket hole screws, assemble two door frames like shown.  The 1x4s will be the sides and the 1x6s will be the slats.

.

Depending on the height of your door, your openings may be different than mine.  Take your door height and subtract 33″, then divide by 5 (the number of openings) and that is how much space should be between the slats.  Make sure you space evenly!  Use a square to make sure you attach everything square.  This is important once you get to inserting the glass panels.

Step 3: Route Out Slots for Glass Panels

Insert a 3/8″ rabbet bit (you could use another size if you wish, I just use 3/8″) into your router.  Adjust the height to 1/8″ and route the open panels of the door.  The corners will be rounded, so square them out using a hammer and a sharp wood chisel.

Step 4: Insert Glass Panels in DIY Modern Sliding Door

Measure the opening in all the panels INCLUDING the routed grove.  Purchase 1/8″ thick glass panels to fit these openings.  Leave a little wiggle room (1/8″ or 1/16″) to make sure they’ll fit.  I buy my glass from a local glass and windshield place, but sometimes big box home improvement stores will cut glass to size for you if you don’t have a local shop.

.

Once you get your glass panels, make sure they fit in the grooves, then spray paint them with frosted glass spray paint. You don’t actually HAVE to do this, but it’s probably a good idea if you’re putting it on a bathroom HAHA.  NOTE: Don’t do this against your garage doors…I just set them here after I was finished to take a picture.

While the spray paint dries, you can paint or stain your two door frames .  I painted mine in Sherwin Williams Naval.  I LOVE THIS COLOR!!  Anyway…You only need to finish the fronts, not the sides with pocket holes.  You can do this later but it’s MUCH easier to do it now haha.

.

Once everything is dry, lay the routed door frame face down on a work surface or saw horses.  Place the glass panels in the openings.

Step 5: Glue on the Back Frame of the Sliding Door

Put wood glue along all the wood pieces–down the sides and across all the slats.  Place the other door frame on top so you kind of “sandwich the glass”. Make sure everything lines up and clamp along the edges to hold in place.  If you have a nail gun, you can shoot a few nails to hold it, but if you don’t, clamps work fine.

.

Putty the nail holes if you used any.  Once the glue is dry, you can sand and touch up the paint in these spots.

Now your door is done!

Step 6:  Prepare the Sliding Door Hardware

Double the width of your door and add about 3-4″.  Get an 1/8″ thick x 2″ tall piece of steel flat stock this length. In my case, it was 7′ long.  This will be your main sliding rail.  You can buy steel flat stock at your local hardware store or metal yard.  It’s cheap!  Also, while you’re there, grab 2 pieces of 1/8″ thick x 1″ wide x 12″ long steel flat stock.  These will be the pieces that attach the pulleys to the door.

.

You can follow the tutorial in this post for how to mount it to the wall.  The only difference will be that unless you have a large obstacle to clear behind the door, you shouldn’t need the long spacers and you also don’t have to have the wood piece on the back either.

.

As long as you can locate your studs, hanging the hardware isn’t too hard 🙂  Of course, you can always buy the sliding door hardware instead of making your own for a few more dollars, but I’m cheap, so I save every penny I can 😉 ha!

.

Once it’s hung, you have a gorgeous new DIY modern sliding door!

I love how the frosted glass lets the light through, but also provides privacy so it can still be used for this bathroom space.

If you didn’t need the privacy, you could totally skip the frosted glass and leave them clear.  That would be cute for an office space or dining room or even a kids playroom.
