How to Install a Laminate Kitchen Countertop: A DIY Guide 2026

Installing a laminate chipboard kitchen countertop is a smart, budget-friendly alternative to solid wood, marble, or stainless steel. While those materials look great, they can stain irreparably. Laminate offers durability and easy maintenance—perfect for a DIY upgrade. Before you start, ensure your new countertop is at least 28 mm thick and cut to size. You can edge the cut sides with a laminate strip using contact adhesive. Ready to transform your kitchen? Let’s dive in.

Getting Started: Removing the Old Countertop

First, disconnect the sink drain and remove the sink itself. Unscrew the corner brackets that hold the old countertop in place, then lift it off. This is a straightforward job—just take your time. For a seamless replacement, consider browsing home improvement essentials to ensure you have all the tools and materials on hand.

Cutting and Fitting the New Countertop

Position your new countertop on the base cabinets, making sure everything is level. Use a pencil to mark the cutout for the sink—leave about 5 mm extra on each side for a snug fit. Cut along the line with a jigsaw, then smooth the edges with sandpaper. Place the countertop back in position and secure it to the cabinets with brackets. For precision cutting, a quality jigsaw from our home improvement collection makes all the difference.

Tools You’ll Need

• Measuring tape
• Cutter knife
• Pencil
• Jigsaw
• Sandpaper
• Silicone gun

Installing the Sink and Finishing Touches

Insert the sink into the cutout, seal the edges with silicone, and connect the drain. Complete the look with a backsplash strip in the same color as your countertop—it usually comes with a support bracket and gaskets. A well-sealed sink prevents water damage, so don’t skip the silicone. For stylish sink options, check out our kitchen islands and carts for inspiration.

DIY Tips for a Perfect Installation

• Always check levels before cutting—precision is key in DIY.
• Use a fine-tooth jigsaw blade for clean cuts in laminate.
• Apply silicone generously but neatly around the sink edge.
• Let the silicone cure fully before using the sink.

Frequently Asked Questions

Can I install a laminate countertop over an existing one?

It’s not recommended. Removing the old countertop ensures a flat, stable base and prevents height mismatches with appliances.

What thickness should my countertop be?

At least 28 mm is ideal for durability and support, especially for sink cutouts.

How do I prevent chipping when cutting laminate?

Use a sharp jigsaw blade and cut from the underside of the countertop (the laminate side facing down) to minimize chipping.

Can I install a granite or quartz sink instead of stainless steel?

Yes, but ensure your countertop cutout is precise and the sink is properly supported. Heavier sinks may need additional brackets.

What’s the best way to seal the sink edges?

Use a high-quality silicone sealant specifically for kitchens and bathrooms. Apply a continuous bead and smooth it with a damp finger.
