Introduction
Kitchen islands can completely transform the look and feel of your kitchen. Not only do they add valuable counter space and storage, but they also create a natural gathering place in the kitchen. However, building a functional kitchen island requires careful planning and execution. In this comprehensive guide, we will walk you through the entire process of building a kitchen island, from initial planning to final installation. We will cover key considerations like layout, materials, and design elements so you end up with an island that looks amazing and works flawlessly in your kitchen. Follow along as we detail this exciting before and after kitchen remodel project.
Planning Your Kitchen Island
When embarking on a kitchen island project, planning is crucial. Rushing into the build without plotting out details like size, placement, and features can lead to mistakes, wasted time and money. Spend time on the front end considering the following factors:
Layout
- Measure your existing kitchen space and sketch out different island size and placement options on paper. Make sure there is enough room for traffic flow around the island. Leave at least 42” for traffic around all sides if possible.
- Consider existing appliances, windows, and doors when determining placement. Avoid blocking or hindering access.
- Decide if you want a fixed or movable island. Movable islands offer more flexibility but are more challenging to build.
Size
- Islands should be proportional to the overall kitchen size. For medium to large kitchens, 36-48” is common. Smaller kitchens can accommodate a 30-36” island.
- The shape also affects functionality. Rectangular islands maximize prep space while rounded or curved islands encourage interaction.
- Choose an overhang size that suits your needs, from 10-15”. Overhangs provide a place for seating and design detail.
Features and Functions
- Determine what you will use the island for- extra seating, food prep, storage, etc. This drives what features to include.
- Consider incorporating an overhang, bar seating, cabinets, shelves,sink, or appliances based on intended use.
- Incorporate electrical outlets if needed, especially if adding an appliance like a cooktop.
Materials
- Sturdy hardwoods like oak and maple are ideal for base cabinets and countertops. Softer woods prone to scratches should be avoided.
- Butcher block, granite, quartz, or laminate make good countertop choices in terms of durability and ease of maintenance.
- Choose finishes that will withstand daily wear and tear, especially for countertops and floors around the island.
Demo: Removing Existing Kitchen Components
For our kitchen island project, the first step was removing existing cabinetry, countertops, and flooring to make way for the new island. This involved:
Cabinet Removal
We carefully dismantled the existing corner cabinet using a pry bar, reciprocating saw, and hammer. The cabinet was removed from the wall and disposed of properly. We were left with a large empty space – perfect for building the new island while keeping existing counters and appliances intact.
Countertop Removal
We used a circular saw to cut out sections of the existing laminate countertop that would overlap with the new island footprint. These sections were also removed and discarded.
Flooring Removal
We used a pry bar and hammer to remove existing vinyl floor tiles from the area under the new island. This created a blank canvas for installing new flooring later on.
After spending 2 days on the demo work, we had cleared the way for constructing the new island base from the ground up. Doing this demolition work upfront made the actual building process much simpler.
Constructing the Base Cabinet
With the space cleared, it was time to build the base cabinet that would support the new island. For this step we used:
Materials
- 3/4” plywood for sides, front, back, and bottom
- 2×4 lumber for base frame
- Wood glue, screws, and nails
- Wood putty to fill holes
Tools
- Circular saw and straight edge to cut plywood
- Drill for driving screws
- Nail gun for attaching plywood sheets
- Jigsaw for cutting out openings
Assembly Process
- Cut plywood sheets to required dimensions with circular saw
- Assemble 2×4 base frame and attach to bottom plywood sheet
- Attach side, front, and back sheets to frame with glue, nails, and screws
- Use wood putty to fill any cracks or holes from nails/screws
Following basic cabinetry techniques, we built a sturdy 36” x 60” base from plywood and 2x4s. Doing the work ourselves saved thousands over buying a pre-made base.
Adding Custom Cabinet Doors
With the underlying base cabinet built, it was time to outfit it with custom doors and drawers. For a built-in look, we wanted doors that matched the existing kitchen cabinets.
To replicate the shaker-style doors elsewhere in the kitchen, we:
- Removed an existing cabinet door to use as a template
- Laid the door on plywood and traced the outline
- Cut out the door shape with a jigsaw
- Sanded edges smooth and applied wood putty as needed
- Primed, painted, and sealed the custom doors
- Attached hinges and handles to match existing hardware
We followed the same process to create false drawer fronts for a seamless look. In just a few hours, we had DIY doors ready for mounting on the new base. Matching the custom doors results in a cohesive look compared to buying mismatched doors.
Adding butcher block countertop
Butcher block countertops pair beautifully with shaker cabinet doors and offer a great work surface. For our island countertop, we selected:
Material
- 3/4” thick, 8 ft. long maple butcher block countertop
Tools
- Table saw or circular saw to cut to length
- Router and tracing bit to cut out sink and stove opening
- Sandpaper to ease edges
- Mineral oil and beeswax to finish and seal
Installation
- Cut countertop 1” shorter than cabinet base
- Dry fit before permanent attachment
- Attach with water-resistant adhesive and brackets
- Finish with mineral oil and beeswax to protect and maintain
The rich wood grain of the butcher block pairs nicely with the simple shaker doors. Oiling and sealing the butcher block will help keep it looking pristine. We left a small overhang for a subtle design detail.
Adding Decorative Island Legs
Decorative legs elevate the look of a basic island while adding support. We opted for a classic look with:
- Turned wood legs in a Provincial style
- Brackets to attach legs to island corners
- Wood glue and screws for secure attachment
This style of leg pairs well with many cabinet door profiles while bringing an artisan touch. Choosing decor-height legs allowed for extra toe-kick space under the island, creating a built-in look.
Attaching the legs with brackets keeps them securely mounted despite daily use. The legs bring both form and function to the island design.
Incorporating Electrical and Plumbing
While our island won’t house major appliances, we still wanted to add electrical and plumbing for functionality. This involved:
Electrical
- Running wiring under the floor and inside the island base
- Adding 2 outlets to one side of the island base
- Installing puck lights under the butcher block for task lighting
Plumbing
- Installing a sink in the butcher block countertop
- Hooking up supply lines and drain pipe within the base cabinet
Having both electricity and water available makes the island even more useful. The outlets allow for plugging in small appliances like a toaster or mixer while task lighting illuminates food prep areas. And the sink provides a secondary cleaning zone in the kitchen.
Flooring and Moldings
The last steps were installing new flooring around the island and adding trim for a polished look.
Flooring
We chose wide plank vinyl flooring in a warm oak tone. Vinyl is durable and waterproof. To install:
- Remove old flooring and prepare the subfloor
- Lay vinyl planks per manufacturer instructions
- Use adhesive and seam sealer for a permanent install
Trim
- Install 1×4” baseboard around the base of the island
- Add matching 1×2” quarter round in front of baseboard
- Use wood putty to fill nail holes
- Finish with primer and paint
The new flooring creates a uniform appearance around the whole kitchen. And the baseboard and quarter round trim lend a quality finished look.
Before and After Transformation
After considerable demolition, building, customization, and finishing, we took our kitchen from dated and dysfunctional to fresh and functional with the addition of this island.
Before
The original layout consisted of old laminate counters, limited base cabinets, appliances crammed into corners, and poor lighting. The work triangle made for frustrating food prep and serving.
After
Opening up the space allowed room to bring in a spacious, centrally located island. The custom cabinetry matches the rest of the kitchen while the butcher block countertop warms up the aesthetic. Stylish legs and Moldings elevate the whole look.
Better lighting, electrical, and the bonus sink optimize functionality. The island creates an open, social space in the kitchen for gathering and entertaining. We achieved an updated, custom kitchen feel for a fraction of the price of a full remodel.
The success of this kitchen island project proves that with careful planning, some key DIY skills, and time invested, you can dramatically upgrade your kitchen without breaking the budget. Let this before and after guide inspire you tackle your own kitchen island project!
