How to assemble and install a blind corner base cabinet

The image shows two assembled corner base cabinets installed side by side, with doors open to reveal internal shelving.

Overview

Blind corner base cabinets are a good way to maximise storage in kitchen corners, making use of tricky spaces. Whether you’re updating your whole kitchen or simply improving your storage options, installing a blind corner base cabinet is a good solution. This guide will walk you through each step, so you can confidently assemble and install your unit with ease.

Safety tip: Always wear the appropriate safety equipment (safety glasses, gloves, ear muffs and a mask, for example) and always follow the instructions for the product or equipment. 

Steps

1Lay out all parts and check them off

Start by unpacking the flat pack and laying out all parts on a clean, flat surface. Take a moment to go through the instruction manual and check off each piece and fixing to make sure nothing is missing. This quick prep step will save you delays later in the build.

2Attach the bottom panel to the back panel

To begin the cabinet frame assembly, take the bottom panel and fix it to the back panel using the screws provided. Adding a bead of exterior timber adhesive here will make the join even more secure. Ensure everything is sitting square as you tighten the fixings. This creates a strong foundation for the rest of the unit and will help keep things aligned as you build.

3Fix the side panels to the base and back

Once the base and back are secured, it’s time to attach the side panels. Position each cabinet panel so that the front edges are flush with the base. You’ll notice that the side panels extend about 20mm past the back edge - this overhang is intentional and gives you flexibility during installation, especially in corners where walls might not be perfectly square. Secure each side panel with the supplied screws, checking that all panels are plumb and tight.

4Install the top support rail

With the sides in place, add the top support rail across the cabinet frame. This component helps stabilise the structure and ensures everything remains square, making it easier to install the unit accurately in your kitchen.

5Attach the adjustable feet

Now that the main cabinet frame is complete, screw the adjustable feet into the base. These will allow you to level the cabinet once it’s in position, helping it line up neatly with your other base cabinets.

6Fit the internal shelf (if included)

If your cabinet kit includes an internal shelf, install it now. Insert the shelf supports into the pre-drilled holes inside the cabinet, then gently place the shelf on top. Make sure it sits flat and is supported on all four corners.

7Install the blind panel

Decide on the orientation of your blind panel. whether the cabinet door will open to the left or right, based on your kitchen layout. If you’re using a 450mm cabinet door, measure and mark a vertical line 66mm from the edge on the side opposite the lugs. Adjust this measurement if you're using a larger door.

8Secure L brackets

Fix three L brackets to the top of the blind panel, three to the bottom, and two to the side. Clamp the blind panel to the cabinet, align it with your marked guide, and then secure it in place with screws through the brackets.

9Install the hinge mounting plates

Start by separating the hinge arms from their mounting plates by pressing the release tabs. Inside the cabinet, line up the elongated holes on each mounting plate with the pre-drilled holes on the blind panel. If your kit includes small plastic lugs, use them to help with accurate positioning. Ensure the round holes on each plate are facing the front edge of the cabinet. Once everything is correctly aligned, fix the plates in place using 14mm screws.

10Attach the door to the hinges

With the plates secured, position the cabinet door so that the hinge arms line up with the mounting plates. Push each hinge arm into place firmly until you hear a click - this indicates the hinge is locked in securely. Test the door by gently opening and closing it to make sure it operates smoothly and sits flush with the rest of the cabinet.

11Position the cabinet in place

Carefully move the assembled cabinet into its designated position in the kitchen, making sure the blind side is positioned against the wall. Use a spirit level to check that the unit is sitting level, and adjust the feet as necessary to achieve a consistent height with your other base cabinets.

12Secure the cabinet to the wall

Once levelled, look for any gaps between the back of the cabinet and the wall. Use packers to fill these spaces if needed. Then, drill through the back panel into the wall studs and fix the cabinet in place using screws that are at least 65mm long to ensure a secure hold.

13Join to other cabinets if needed

If you’re installing the corner base cabinet alongside other base units, clamp them together once aligned. Drill pilot holes through the side panels and screw them together to create a seamless, stable join between cabinets.

To finish up, double-check that the door opens and closes smoothly without rubbing or catching. Make any final hinge adjustments as needed, and then give the cabinet a wipe down to remove dust and fingerprints.
