According to the 2025 UK Houzz Kitchen Trends Study, 92% of homeowners upgraded their worktops during a kitchen renovation. Of them, 42% chose engineered quartz. That’s not an accident. Homeowners wanted materials that were durable, easy to clean, and had a beautiful look and feel. Little wonder they chose quartz.
You don’t need to rip out your entire kitchen to transform it. Yes, taking out your existing worktops and replacing them with quartz can totally transform the space, but it can be costly too. Another popular and premium option is quartz overlay worktops. These crisp, smooth, and hard-wearing, quartz worktops are overlaid onto your existing countertops. They sculpt the space, lifting it and refreshing the overall aesthetic, but how do they compare to full quartz worktops? Let’s take a look.
What is a Quartz Overlay Worktop?
A quartz overlay worktop is a slim quartz surface designed to sit directly on top of your existing worktop. There’s no ripping out the entire kitchen and starting again. Instead, the new quartz layer is bonded over it. It instantly gives your kitchen a stone-fresh finished look with far less disruption.
Here are a few extra details:
- The overlay is usually 10–15mm thick, much slimmer than standard quartz slabs.
- It’s custom-cut to your kitchen layout, including cut-outs for sinks and hobs.
- Engineered quartz is made from 90-95% natural quartz stone alongside resins and pigments for strength and colour consistency.
- Edges are neatly finished, so the overlay looks full-depth once installed.
Why Choose Quartz Overlay for Kitchen Worktops?
Most current kitchen worktops are ugly but still strong. They’re not going to collapse anytime soon, but they bring down the whole aesthetic of your kitchen. Quartz overlays follow your existing worktop layout, offering an affordable yet high-end way to upgrade your entire kitchen.
The Benefits of Quartz Overlay Worktops
- Minimal disruption, faster installation. Quartz overlay worktops go straight over your existing surface, so there’s no ripping things out or turning the kitchen into a dust zone. In many cases, the job’s done in a day.
- Cost-effective upgrade. Because the old worktop stays put, you save on removal, disposal, and extra labour. You get that premium quartz finish without paying full replacement prices.
- Same quartz performance. Even though it’s thinner, the quartz overlay still gives you a hard-wearing, non-porous surface that’s easy to clean and stands up well to everyday kitchen use.
- Ideal if the kitchen itself is still solid. If your units are fine but the worktop looks tired or dated, an overlay can completely change the feel of the space without a full renovation.
- Cleaner, greener option. Reusing what’s already there means less waste, and with clean edges and modern finishes, the end result looks just as sharp as a brand-new quartz worktop.
- Complete a cost effective Kitchen renovation. When paired with freshly resprayed cabinets, quartz overlay worktops can completely transform your ageing kitchen.
Durability and Lifespan of Quartz Overlay Worktops
Wood scratches, laminate surfaces bubble and stain and marble and granite chips.
Quartz, in contrast, is extremely durable and hard-wearing. It scores about 7 on the Mohs hardness scale, which puts it far above other kitchen surface materials. Only things like diamonds, rubies, and certain industrial abrasives are harder.
Even if you chop directly on the surface, everyday kitchen knives won’t scratch quartz (although we don’t recommend it). You only use a chopping board to protect your knives, not the surface.
Because it’s an engineered stone, it’s less vulnerable than natural marble or granite. These surfaces can require oils, sealants, and heavy chemicals whereas quartz wipes clean with warm, soapy water.
How are Quartz Overlay Worktops Installed?
Installing a quartz overlay worktop works a little differently from other kitchen installations. Because the existing kitchen stays in place, your fitter will need to thoroughly inspect it before starting.
Here’s what to expect:
- Assessment of your existing worktop. Unless your existing worktop is solid and sturdy, a quartz overlay cannot be fitted. Your fitter will determine if it’s structurally sound.
- Precise measuring and templating. Your kitchen is carefully measured, including cut-outs for sinks, hobs, and edges. The quartz needs to fit exactly with no awkward gaps.
- Manufacturing the quartz overlay. The quartz is cut to size off-site, typically at 10-15 mm thick. Edges are finished and polished, so it looks full-depth once installed.
- Surface preparation. The existing worktop is cleaned and levelled. The bond has to be strong and flawless for longevity.
- Bonding the quartz overlay in place. The quartz is laid over the existing worktop and bonded using specialist adhesives.
- Final finishing and checks. The installer checks alignment, cleans the surfaces, and ensures all edges, joins, and cut-outs are sealed and refined.
How Long Does It Take to Install Overlay Worktops?
Usually, a quartz overlay can be installed in a single day.
The installer, like The Spraying Company, may visit the home a few days (or even weeks) before to take the measurements. The quartz is then cut and brought to your home. Because the existing worktop remains in place, the fitting process is clean and fast.
How Much are Quartz Overlay Worktops?
The cost of quartz overlay worktops depends on the size of your kitchen, the number of cut-outs, and any additional features, e.g., a splashback.
Quartz overlay is much cheaper than a full quartz slab. Plus a lot less than a full kitchen worktop renovation. They can be installed at the same time as kitchen respray. They’re a great add-on while you’re creating your dream kitchen.
Who Can Install Quartz Overlay Worktops in My Kitchen?
A quartz overlay worktop should only be installed by an experienced professional. Without the right measurements and expertise, the quartz often doesn’t fit perfectly into the existing kitchen. That’s a problem considering the stone is bonded directly onto the current countertop. If it’s not done right, the existing kitchen is ruined beyond repair.
The Spraying Company offers beautiful, clean quartz overlay worktops that transform your ageing kitchen countertops. Available in a range of colours, there’s an option for every kitchen.
Plus, with our kitchen spraying services, we can update your cabinets and cupboards as well, giving your entire kitchen an overhaul at a fraction of the price of a replacement.
