I have been wanting refresh our hallway bathroom for a long time. However, I wasn’t ready to completely renovate it just yet. So, I decided to partner with my favorite paint brand—Behr—and begin phase 1 of our bathroom refresh. I also completed my first-ever solo power-tool project and could not be more thrilled with the outcome!

How to pick a Bathroom Accent Wall Color:

When picking my paint color, I knew I wanted something a little moody but still inviting. BEHR’s 2020 Color Trends color, Dragonfly PPU12-03 was just the color I was looking for.

I got a sample of the color and went home to give the paint a test on my walls. I fell in love the moment I opened the lid! The color was soft, but rich and it was just the perfect shade for our bathroom.

I stopped at the Home Depot store, picked up a gallon of BEHR PREMIUM PLUS PPU12-03 Dragonfly Interior Satin Enamel Paint and was ready to get started!

We ALWAYS use Behr Premium Plus paints in our home because we love that it is a durable paint & primer in one. Plus, using Satin Enamel Paint will be perfect for the bathroom with the added moisture from the shower.

And have you seen BEHR’s Color of the Year: Green Back to Nature S340-4?!!  It’s a restorative and meadow-inspired green, I may just need to find a place to use that color soon.

Bathroom Before :

Let’s take a quick peek at my “before” bathroom. We have a few must-stay items, namely our very Southwest saltillo tile (a burnt orange color) and our current blush pink fixtures (toilet, tub and sink). I thought the teal in Dragonfly PPU12-03 complemented the orange tones in the room.

How to make a modern board and batten wall?

Board and batten can take a few different looks. It originally has a bit of a farmhouse look to it, but I believe by using fresh bold paint colors and also by installing it taller than a typical chair rail height – you can create a much more modern look.

Let’s get into how to build yours, below.

Determine Board and Batten spacing

Prior to starting this project, I drew out and decided on my dimensions for each piece of my board and batten wood treatment.

I wanted my accent wall to be about 55″ in height and based on the width of the space I was working with, I decided to space my board and batten with 6 vertical boards roughly 19″ apart.

Remove baseboards

The first step to creating a modern board and batten accent is to remove the baseboard along the wall. I used a utility knife to score along the top caulked seam and a prybar to pop it all off.

Bathroom update, remove baseboards

Paint Wall and all Boards

Based on the total height of your board and batten design (mine was 55″ tall in total), measure and mark 55″ with your pencil from the floor. You are marking the total height of your board and batten design so you know how high to paint the wall basically.

Using a paint roller, give your wall a first coat of paint. I was immediately smitten with the color! BEHR PREMIUM PLUS Interior Satin Enamel Paint in Dragonfly PU12-03 for the win.

While the wall was drying, I painted all of my trim pieces. I had five 1x4x8 pre-primed MDF boards for the batten and one 1x2x8 pine board for the top trim. I love BEHR PREMIUM PLUS Interior Satin Enamel Paint for bathrooms because of its long-lasting finish and that it’s washable.

Also, I can’t stop with this color… it’s the perfect moody but cheery color. Behr Dragonfly for life.

Once the trim pieces were dry, I placed my baseboard on the ground and made sure it was level. Then, using a stud finder, I marked all of my studs at 24″ on center.  I also used a magnetic stud finder for certain parts – I honestly recommend having both types as I used them both nonstop on this project.

Bathroom Update-Behr-Step level and stud finder

Remember, this was my first ever solo project using power tools. My husband gave me some basic direction that morning before he left for work but otherwise, I completed this project on my own.

Secure your bottom baseboard

I then used a pneumatic nail gun to secure my bottom 1x4x8 board to the studs.  

I ended up nailing every 8″ to make sure my board was flush against the wall. FYI our wall was exactly 96″ wide, so I didn’t have to cut the two main horizontal boards.

Measure, measure, measure

Once my bottom baseboard was secured, I measured from the top of that board to ensure that the remainder of my wood would stay level.

Since I wanted my entire height to be 55″ from the top of my baseboard, I marked at 45 1/2″, 49″, and 49 3/4″ along three different spots for the next installation steps.

I then installed the main top trim 1x4x8 board using the nail gun.

I had calculated that I would need six vertical boards in total. So, next I began measuring from the top of my bottom baseboard to the bottom of my top board to get the exact measurement each vertical would need to be cut. They were each 47″, give or take a little bit.

Cut vertical boards and secure to wall

Using a miter saw, I made each of those exact cuts and using the nail gun, secured them to the wall. 

In addition, I also put a nail diagonally where each vertical board met the baseboard and top board for extra strength.

I made sure to tamp each of those diagonal nails in with a nail setter and hammer because it was difficult to get the nails flush in the wood with that tight space using with my nail gun.

Spackle and Caulk

Next, I filled all the nail holes with spackling. I used my finger to put the spackle in all the holes. Once it was dry, I used a lightweight sandpaper to remove any excess spackling.

I applied paintable caulk on all the trim edges next. I was so worried the caulk would eliminate all my perfect straight lines, but once it was dry and I painted over it, it really made everything look perfect.

Add top ledge trim board

My final step was adding the last 1x2x8 pine top trim piece. One end of the pine trim hit our door jam, so I ended up having to hand-saw a small notch out of the board to make sure it fit properly.

A few more nails to secure that piece, and the construction portion of this project was complete.
