All About Shiplap Trim: Corners, Edges and Baseboards

Sharing is caring!

Learn all about shiplap trim. Finishing off shiplap with trim will give it a finished look and hide any uneven edges.

I’ve used shiplap as accents in several rooms of my home. I love the classic touch that it adds to a room.

My favorite part of installing shiplap is adding the trim. This detail really brings it to life and can give it a different look depending on your choice.

Shiplap Trim: Corners

Corners can be tricky, but luckily I have a few solutions.

Inside Corners

In my kid’s bathroom, my cuts were perfect and I was able to just caulk the seam with paintable caulk. This creates a seamless look.

In my bathroom, I used quarter round. My cuts in this room were not as exact, so quarter round was able to hide this face. When painted, the trim disappears.

Alternatively, you can use cove molding.

Outside Corners

For outside corners, I always use corner trim. Even if my cuts were perfect, I would worry about the corner being too sharp if you scraped up against it.

It could do with a paint touch up, but I’m considering repainting the whole room, so that will wait.

The corner trim provides a nice, rounded corner.

How to Cap Off Shiplap

You have 2 options for the top of shiplap. The trim can partially cover the top and a small portion of the shiplap or it can sit on top of it.

In my kid’s bathroom, I chose the first version. The trim is L-shaped with a lip that fits perfectly over the top of the wood. (See photo above.)

In this bathroom, I chose a more modern look and opted for 1 x 3’s that sit on top of the wood.

Baseboards for Shiplap

Baseboard choice depends on what type of shiplap you use. If you use thicker shiplap, you will need a thicker baseboard.

In my kid’s bathroom, we removed the old baseboard and replaces it with 1x 4’s. This creates a modern look.

For a traditional look, consider adding a thicker baseboard with more details.

In my bathroom, we used thin luan for the shiplap, so we were able to keep the old baseboards.

Shiplap to Tile Transition

There are a lot of options to cover where the tile meets shiplap.

You can use any trim with a flat back for this spot. For a modern look, consider using plain trim (like lattice wood).

In this bathroom, I used a more decorative trim for an added detail.

Finishing Shiplap

The most important part of adding trim to shiplap is caulking the edges. Caulk makes the entire project come together and look seamless.

For best results, use paintable caulk.

Be sure to paint the caulk even if it’s the same color as your shiplap. Unpainted caulk is impossible to clean and attracts dust.

Quick caulking tip: cut a tiny opening with a utility knife, not the cutter on the caulk gun. This will prevent a lot of the mess from excess caulk.
