DIY: How to Build a Mobile Kitchen Island

diy mobile kitchen island

If you have a small kitchen or one without much counter space, one way you can create additional prep space is with a DIY mobile kitchen island. But if you cruise around online looking for mobile kitchen islands, you’ll find they can range in pricing from $75 to $1,500, with quality ranging likewise.

Yikes! It’s far more reasonable to build your mobile kitchen island than to break the bank buying one. So we teamed up with Jamie Schmitt to create this mobile kitchen island.

Jamie designed this DIY kitchen island on casters so it can be moved easily to anywhere prep space or extra storage is needed. With its mobility and versatile design, it can easily be used for entertaining purposes like a bar cart, too.

For this kitchen island, Jamie used RTC2Z connectors, which make this a project that even a beginner DIYer can complete from start to finish. Simpson Strong-Tie RTC2Z connectors allow DIYers to connect wood pieces in a rock-solid 90°angle quickly and easily. You can leave the connectors in the original ZMAX®finish for extra corrosion resistance, or you can paint them. We used Rust-Oleum Satin Black spray paint for this project.

The nice thing about this DIY kitchen island is that it’s easy to build, easy on the eyes and easy on your wallet. Get the free mobile kitchen island plans here!

How to build a DIY Mobile Kitchen Island

Step 1: CUT LUMBER TO SIZE

Use straight cuts.

Step 2: ATTACH LEGS TO CONNECTORS

Attach RTC2Z connector 5″ down from the top of each leg (A) with SD8 screws. Position legs so their wider sides face each other.

Step 3: INSTALL HANGER ROD

Using a 1⁄2″ drill bit, create holes 9″ from the top of each leg and 1″ from the outside of the island. Insert metal rod and place S hooks in preferred orientation (facing in or out).

Step 4: ATTACH RAILS AND CASTERS

Attach upper front rail (B), upper back rail (C) and upper side rails (D) to RTC2Z connectors with SD8 wafer- head screws. Attach lower front rail (B), lower back rail (C) and lower side rails (E) to legs with (16) 2″ Deck-DriveTM DSV Wood screws. After lower front and back rails are attached to lower side rails (E), install rolling casters to side rails, front and back rails and legs with 2″ DSV screws. Use two screws per leg and one screw for the back rail and side rail.

Step 5: ATTACH UPPER SHELF

Assemble widths of 1×6 lumber pieces sufficient to form the 24″ (wide) x 20″ (long) upper shelf (F). Begin at ends, notching end pieces to fit around legs. Measure gap in middle of shelf, and cut center piece to fill it. Hammer 2″ finish nails through shelf pieces into supporting rails.

Step 6: ATTACH TOP SHELF

Attach the top shelf (G) by centering the shelf over the island to ensure overhang is equal on opposites sides. Slide 2×2 x 20″ (I) top attachment to insides of leg and clamp to top. Repeat for the other side. Flip island over and screw wood to the top with 2″ DSV screws.

Step 7: ATTACH BOTTOM SHELF

Clamp bottom shelf (H) to bottom rails. Turn island over and place
A21 connectors midway along each bottom rail. For each connector, screw two 1″ pan-head wood screws into rail and two more into bottom of shelf.

Note: installation is easier if wood staining and painting of RTC2Z is done before assembly.
