Key takeaways
- Most older kitchens can take a new quartz, granite or solid-surface top on the cabinets already there.
- Cambria, a quartz maker, wants the bases flat within 1/8 inch over 8 feet, the sink base has to be dry and solid, and openings like the dishwasher need support on three sides.
- Cambria lists its 3 cm quartz at about 15 pounds per square foot, so a soft sink base or a box pulling off the wall has to be fixed first.
- If the boxes are sound and the doors are tired, refacing them on the same job lets one consultant plan both together.
The oak cabinets in your Anderson Township kitchen went in around 1990, and they still close. The laminate on top of them is done: a burn ring by the stove, a seam by the sink you can feel with your thumb. You'd like quartz or granite, and you'd like to skip the part where the whole kitchen comes out. You can get new countertops without new cabinets in most older kitchens. A stone top doesn't care how old the boxes under it are. It cares whether they're flat, whether the sink base is solid, and whether the openings in the run have something to sit on.
The questions below are the ones we hear at the kitchen table, grouped by what they're about.
New countertops without new cabinets: what the boxes have to carry
Can I get new countertops on the cabinets I have?
Yes, if the boxes are sound. Our kitchen FAQ says you can start with new countertops on their own, without a full remodel. The top sits on the cabinet boxes, so the boxes have to be solid, flat and fastened to the wall.
The five-minute check of the cabinet boxes covers the sink base, the shelves and the face frames, and it's worth doing before anyone measures. Everything below assumes your boxes passed it.
How heavy is a quartz or granite countertop?
Heavier than the laminate it replaces. Cambria, a quartz maker, lists its 3 cm slab (about an inch and a quarter thick) at about 15 pounds per square foot, and its 2 cm slab at about 10.
A 10-foot wall of base cabinets with a standard-depth top comes to about 20 square feet. At Cambria's 15 pounds per square foot for 3 cm, that's around 300 pounds of quartz on that one wall, before the sink full of dishes. Granite is natural stone, so ask the fabricator for the weight of the slab you pick.
Sound cabinet boxes carry that weight along their sides and backs. The weak spots are the places where water has softened the wood, and the places where there's no box under the top at all.
Do my cabinets have to be level for a stone countertop?
They have to be flat, which is close to the same thing. Cambria's installation requirements say the cabinets must not be out of plane more than 1/8 inch for every 8 feet, and that the countertop gets shimmed onto the same plane at installation.
A stone slab doesn't bend to follow a dip in the run, so the installer shims it flat or the low spot shows up as a gap or a rocking piece. The same document ties its seam limits to the level and straightness of the cabinets, so a crooked run shows at the seams too.
You can get a rough read tonight. Lay a 4-foot level on the old countertop along the front edge, then front to back, and look at the bubble. A laminate top sits right on the cabinets, so it gives you a fair idea of what they're doing. Then check where the counter meets the dishwasher and the range. A small difference is what shims are for. A run that drops a half inch toward the middle, in a 1960s ranch where the floor has settled over the basement beam, is something to point out to the consultant.
The sink base, the openings and the overhang
What does the sink base have to hold?
More than the cabinets on either side of it. The sink base has a large hole cut in the top above it, and with an undermount sink, the sink itself hangs from the underside of the countertop. Cambria requires undermount sinks on 2 cm and 3 cm tops to be held with sink clips. It also says every cutout needs extra underside support within 3 inches of the opening, on all sides.
That puts a lot on two cabinet sides that have spent 30 years under a drain and a faucet. Swollen side panels, a soft cabinet floor or a musty smell mean the sink base has been wet. The soft floor under your kitchen sink walks through finding that leak. Get the leak fixed and the damage looked at before a stone top goes on that box.
What about the dishwasher opening and the corner cabinet?
Both are places where the top spans open air. Cambria requires vertical support on three sides of an appliance opening such as a dishwasher. For a large box like a corner or lazy Susan cabinet longer than 36 inches or deeper than 24, it asks for extra front-to-back support at least every 36 inches.
In an older kitchen, the dishwasher is sometimes a later addition squeezed between two boxes, with a strip of wood across the front and nothing along the back wall. Open the dishwasher, look up, and see what the countertop rests on. If the answer is the old laminate top and a couple of brackets, the stone needs more than that.
Can I add an overhang or a breakfast bar to my old base cabinets?
A small one, yes. A seating bar is a different job. Cambria caps any overhang at one-third of the countertop's depth, even with brackets, and says a 3 cm overhang past 15 inches needs corbels, the brackets under the stone.
So if you're picturing two stools at the end of the peninsula, say so at the first visit. The bar decides how the stone is cut and what has to go under it.
Solid surface on older cabinets
Is solid surface easier on old cabinets than quartz or granite?
It's a thinner top. DuPont stocks every standard Corian color in sheets 12 mm thick, about half an inch, against about an inch and a quarter for a 3 cm stone slab.
Solid surface still wants flat boxes and a dry sink base, and it still needs a trivet at the stove. It's a fair pick when you like the idea of a top whose scratches you can sand out. Quartz, granite or solid surface compares the three on heat, stains, scratches and repairs over 20 years.
Refacing the doors on the same job
Should I reface my cabinets when I get new countertops?
If the boxes are sound and the doors are worn, doing both on one job makes sense. Refacing replaces the doors, the drawer fronts and the veneer on the face frames, and the boxes stay where they are. That's the same condition a stone top needs: solid boxes you're keeping.
Three reasons to decide together:
- You pick the door color and the countertop with the samples side by side, in your kitchen light.
- One design consultant plans both together.
- The new top's front edge sits over the new face frames, so the two get measured to each other.
If the doors are fine, leave them. A new top on oak doors in good shape is a common kitchen, and nobody should sell you fronts you don't need.
When to replace the cabinets instead
When the boxes fail the check, or when you want a different kitchen. A soft or swollen sink base, face frames pulling off the boxes, a wall cabinet leaning off the wall, or a layout you'd change all point to new cabinets. A stone top cut to fit boxes you'll pull out in five years is money spent on the wrong end of the job.
| What you find | What it means | Next step |
|---|---|---|
| Flat run, dry sink base, tight boxes | Sound cabinets | New top on the cabinets you have |
| A dip under 1/8 inch over 8 feet | Within the stone maker's limit | Shims at install |
| Dishwasher with nothing along the back | An open span under the top | Support at the opening |
| Sink base soft, swollen or musty | Water damage in the box | Fix the leak and the box first |
| Boxes coming apart, or a layout you'd change | Cabinets near the end | New cabinets, then the top |
What happens when we measure
Bulldog installs quartz, granite and solid-surface countertops, along with the backsplash, the sink and the faucet that go with them. A design consultant comes out, looks at the cabinets you're keeping, and measures. Ask them to open the sink base and look at the dishwasher opening while they're there. Before anything is cut, our team makes a digital template of your existing layout so the stone fits the cabinets and walls you have.
The price comes from that visit. The things that set it are the square footage, the material and color, the edge and sink cutout, and the backsplash. If a box is worn or damaged, the consultant will say so at that visit. You get a written quote after the measuring, and financing is available on approved credit.
Many kitchen updates take a few days, and countertops on existing cabinets are the kind of job that runs in days, not months. A full kitchen with new cabinets takes longer, and your project coordinator gives you the schedule before work starts. Our own crews do the installation, and the products and the work carry a lifetime warranty for as long as you own the home.
If your old top is a laminate with a ridge at the sink seam, what replacing a laminate countertop involves covers the tear-off and the backsplash strip behind it. When you're ready, look through the colors and edges on our countertops page, then call (513) 657-3750 and have your level readings written down for the consultant.
A new-looking kitchen in days, not months walks through every part of the kitchen in order: what to keep and what to replace.
