Kitchen Island Makeover: Adding Trim

Adding trim to a kitchen island is a budget friendly way to build your dream island! Upgrade an existing island or enhance a brand new design. Step by step tutorial and before and after photos included.

When we took on this kitchen remodel, it was quite the plight. What you see today was not the original concept. Honestly, there were points during the renovation where I half expected Ty Pennington to show up and start narrating. However, the finished space is worth every sleepless night and squabble over whether to paint the kitchen cabinets or installing new countertops.

We’ve previously highlighted how to build a kitchen island and how we made it into a stone veneer. However, something was just not sitting right with me. Then one day out of nowhere, BAM! It hit me like a bolt of lightning. The island needed a makeover.

The Before

The original, builder grade bar looked like this:

This is the original island that was installed in the house and our plans for it. These details were pivotal in transforming the island’s aesthetic to match the overall kitchen design scheme. Adding trim and corner columns provides a full-bodied and traditional style to enhance the piece.

In fact, it blends so seamlessly, you’d never guess it wasn’t part of the original bones of this home. If you aren’t sure what style for your kitchen island, check out 20 Gorgeous Kitchen Remodel Ideas for more DIY inspiration and a variety of different layouts.

Recommended Tools and Supplies

While I understand that kitchen island designs are often different, as well as the size. Our kitchen island base is 5 feet wide x 4 feet deep. These are the basic supplies one need for adding a design such as this. Links are included if you are not familiar with a tool.

• ½ x 6 boards in poplar, oak, or birch (varying lengths)
• ½ x 4 boards in poplar, oak, or birch (varying lengths)
• (2) Traditional Corner Posts
• (2) 4×8 feet sheets of Smooth ¼ or ½-inch plywood
• (14 ft) baseboard trim
• 1.5-inch finishing nails
• Nail Setter or Brad Nailer
• 180 grit sandpaper
• 220 grit sandpaper
• Random Orbital Sander
• Wood Filler
• Paintable caulk
• Miter Saw (highly recommend) or Mitre Box

*Poplar isn’t much harder than yellow pine, but birch is more expensive. We painted our island and didn’t want the recessed grain that oak can show over time. Therefore, we used a mix of poplar in places that wouldn’t get as abused and birch for better rigidity on the front.

** Half inch thick plywood is sturdier and what worked best for our design. However, you can use thinner if you don’t have enough overhang or will get rigidity in other ways like the framing or smaller boxes.

1. Remove Any Existing Trim or Decorative Facing

The first step, in our case, was to remove any existing trim and make the faces as level as possible. Because we had built the bar out previously, we only removed the previous stone veneer walls. Underneath, it was a nice flat surface to work with.

2. How to Wrap a Kitchen Island

This part is not always necessary. If you have a smooth, paintable surface after removing the trim, then you don’t need to add a new face.

For our design, it was best to wrap some plywood sheets because we had previously drywalled and we removed that. Home Depot cut the plywood to size for us to make it easier to haul home. Fair warning though: Always, always double check their measurements before you get home!

We added these beautiful corner posts to anchor everything together and give the island some dimension. The posts are square, so we cut a long notch out of the back to fit the post over the corners of the bar, but you could design the framing so that the corner posts fit into it square. Another idea is to use them like table legs under the extended countertop. Here are several examples. If you don’t want corner posts, using flat strips to make a corner is very nice too.

3. Cut the Trim and Decorative Elements

Making a high-end looking trim design is all about layering decorative trims.

We started out making a traditional wainscotting frame with 3 sections on the front and 2 on each side. The bottom is slightly lifted because it will be covered by baseboards and quarter round.

4. Add baseboards

Now, I loooooove custom looking trim work. For most, some nice, simple baseboards would have been beautiful. However, we also created our own baseboard design. The shot above shows the cuts we made around the corner column. You can also see that we laid a small decorative trim on top of the ½×3 poplar board to create a taller, custom baseboard.

***Tip: We used a brad nailer for all of our nails, but if you use a regular hammer and finishing nails, you will need a nail setter to sink the nails into the wood and fill them for a smooth face.

Tips for Making Miter Cuts

Mitre cuts are essentially a 45 degree angle cut, rather than a straight cut. Our corner columns and joints use several of them.

1. You can use a Miter saw (my preference), table saw, or miter box. I would only recommend a miter box for ¼ inch thick boards. We always double check the chop saw or table saw with a carpenter triangle to make sure it’s straight up and down.
2. Always measure from the longest side of the cuts.
3. If you plan on painting it, the corners are much more forgiving with wood filler or caulk.
4. Check twice to make sure you are cutting the correct angle direction. We have caught ourselves many times about to cut the reverse angle.

The Secret to Pro looking Trim

Although we were pretty good about any gaps and ridges, a painted surface is going to have to be filled. I use both wood filler and caulk, but how do you know which to use and when?

Wood filler is used for flat surfaces that are on the same plane (yes, geometry!) and surfaces where I need some structure to feel smooth. Nail holes or where two boards are very slightly misaligned height wise are examples, I generally don’t fill gaps between boards with wood filler because often wood filler will crack over time when the two boards move independently.

The kitchen remodel is finally finished! You can see the full kitchen makeover here. We painted the bar in a custom mix of Lamp White and Raw Silk from Fusion Mineral. Because this is a high traffic piece, I sprayed a water-based polyurethane from Benjamin Moore. I have a post on my favorite maximum protection topcoats for furniture.
