Add Geometric Trim for an Easy DIY Kitchen Island Update
The builder-grade island. You can’t complain because you are lucky enough to have an island, but overall the design is pretty blah. On top of that, the flat paint finish on the island is a magnet for jean stains and scuffs, so it never really looks clean.
You don’t want to change the structural elements of the island, but you’re looking for something more practical (and pretty).
Phew, you’re in the right place! Today we’re going to talk through the steps of how we transformed our builder-grade kitchen island into a design focal point of our island–all for less than $50!

How to Upgrade a Builder Grade Kitchen Island Using Trim

Step 1: sketch out your design
Sketch out your design using chalk. Once you get the design where you want, go over it with painters tape. If you want some design inspiration, be sure to download the 6 free design ideas at the bottom of this post.
Step 2: sand
Sand all of your boards using 120 grit sandpaper or higher.
STEP 3: cut your corner moulding
Cut your pine corner moulding to to the appropriate size (the distance between your lower moulding and your upper moulding) using your miter saw with a fine tooth saw blade.
Step 4: attach corner moulding
Attach your corner mouldings using liquid nails. While the glue is drying, you can use painters tape to reinforce them to the wall rather than holding them yourself.
step 5: cut your boards
If you have a spare board, use your miter saw to cut it at a 45-degree angle. Then clamp the board you are wanting to cut to this angled board. This will give you a guide for your hacksaw. You could also use a miter box.
Cut any pieces that span fully from bottom trim to top trim. Cut the first piece approximately 2-3″ longer than it will need to be. Once you cut it, bring it to your island and use a pencil to mark the exact size the board needs to be. Use this measurement for all of your boards than span fully from bottom trim to top trim so that they will all be parallel (even if they weren’t fully parallel in your sketch).
Step 6: attach your boards
Remove the tape and attach your full-length boards to your island using nails. We used 3 nails in each of our 38″ boards.
Next, let’s move on to the perpendicular boards. You can use a pencil to “cut” your tape to the exact length that you need your boards to be. Use your hacksaw to cut your boards. Attach your boards using nails.
Continue cutting your tape, cutting your boards, and attaching them until your design is complete.
step 7: prep and paint
Once all of your boards are secure, fill all of the nail holes and seams between boards with wood putty. Be sure to overfill all of the holes because the wood putty will shrink when it dries. Once the wood putty is dry, sand off the excess using 120 grit sandpaper.
Caulk every place that the boards meet the wall.
Once the caulk dries, it’s time to paint! We used our paint sprayer, but you can paint with a brush and/or roller. We recommend getting a semi-gloss or glossy paint to reduce the number of stains and scuffs. If any dirt does get on the island, a semi-gloss paint will be much easier to clean than a flatter finish.

Thanks for sharing, I really love how this project turned out! I’m getting my kitchen redone by a cabinet painter in a few weeks & I’m planning on having them update my kitchen island too. Your photos have been super helpful in trying to help me decide what color and style I want!
