A dishwasher mounting bracket secures your dishwasher so it doesn’t tip forward when you pull the loaded door open. With laminate countertops, the dishwasher screws straight up into the underside of the counter. With granite, quartz, marble, or any stone countertop, you cannot screw into the stone — so you need a bracket that anchors the dishwasher to the cabinets instead. After 10 years installing stone countertops, I mounted a dishwasher bracket on nearly every job. Here’s how the brackets work, the types available, the 4-step install, and the products worth buying.
Why Stone Countertops Need a Special Bracket
Every dishwasher ships with small metal mounting tabs at the top, designed to be screwed into the underside of the countertop. That works fine for laminate or wood. It does not work for stone — you can’t drill a screw into granite, quartz, or marble without specialized diamond tooling, and you wouldn’t want to anyway.
As House Digest’s installation coverage notes, without a proper anchor a stone-countertop dishwasher is held in place only by friction and the water/drain connections. Pull the door open with a full load of dishes on it and the whole unit can tip forward — a real hazard, especially with children around. The bracket solves this by transferring the dishwasher’s anchoring from the (un-drillable) stone to the (perfectly drillable) cabinet boxes on either side.
Types of Dishwasher Mounting Brackets
Side-mount brackets attach to the dishwasher’s sides and to the cabinet face frames on either side. The most common and most secure option for stone-countertop installs. The classic folding-ear brackets and systems like Granite Grabbers fall in this category.
Top-mount brackets secure the dishwasher to the underside of the countertop edge. Useful when side cabinet access is tight, but they require a fastening surface — with stone, that usually means a bracket that grips the counter’s underside rather than screwing into it.
Rear-mount brackets attach the dishwasher to the back wall or rear cabinet. An alternative when side and top mounting are both impractical.
Universal brackets are adjustable systems — some appliance makers like Frigidaire sell granite-countertop install kits directly — designed to fit a wide range of dishwasher models and cabinet configurations — the safest pick if you’re not sure exactly what your dishwasher needs.
How to Install a Dishwasher Mounting Bracket: 4 Steps
For the common side-mount folding-ear bracket, this is a 5-to-10-minute job. Tools: a drill, a small drill bit for pilot holes, and a screwdriver bit.
Step 1: Fold the Bracket Ears Down
The bracket has two folding “ears” that fold down so the screw-through side faces outward toward the cabinet face frame. Fold both before positioning.
Step 2: Drill Pilot Holes
Hold the bracket in position against the side of the cabinet face frame, snug up against the underside of the stone countertop. Drill a small pilot hole using the bracket itself as a guide. The pilot hole is critical — it prevents the cabinet face frame from splitting when you drive the screw.
Step 3: Screw the Bracket to the Cabinet
Using a drill on low torque, screw the bracket into the face frame. Keep it pushed all the way up against the underside of the countertop so the dishwasher will sit at the correct height. Repeat on the other side.
Step 4: Attach the Dishwasher to the Bracket
With the dishwasher fully installed and connected (water, drain, power), fold down the dishwasher’s own metal mounting tabs and drive the small screws from the bracket kit through the tabs into the bracket. The dishwasher is now anchored to the cabinets and won’t tip.
Recommended Dishwasher Mounting Brackets
Four brackets I’d put on a customer’s job:
Granite Grabbers Dishwasher Mounting Brackets — the installer favorite. A side-mount system with a built-in threaded nut so the screw hole never strips, requiring no glue and no drilling into stone. The most reliable choice if you want one recommendation.
Universal dishwasher mounting bracket kit — an adjustable kit that fits most dishwasher models and cabinet setups, good when you’re not certain what your specific dishwasher requires.
Side-mount dishwasher bracket set — a straightforward folding-ear set for standard cabinet-frame installs.
Granite countertop dishwasher install kit — a kit specifically marketed for stone-countertop installations, with the hardware bundled.
If you’d rather not buy a dedicated bracket, the old installer trick still works: adhere a strip of plywood or a 1×2 wood block to the underside edge of the granite with construction adhesive, let it cure, then screw the dishwasher’s tabs into the wood. The purpose-made brackets are cleaner and faster, but the wood-strip method is a valid backup.
Who Installs the Dishwasher Bracket?
When I installed stone countertops, my crew mounted the dishwasher brackets on every job — it’s a standard part of a professional countertop installation. If you’re having new countertops installed, ask your fabricator whether dishwasher bracketing is included. Many include it; some leave it to the appliance installer or the homeowner. Confirm before install day so the dishwasher doesn’t get left unsecured. If you’re doing it yourself after the fact, the 4 steps above take under 10 minutes.
Frequently Asked Questions
Can you screw a dishwasher into a granite countertop?
No. You cannot drill a standard screw into granite, quartz, or marble — it requires diamond tooling and would risk cracking the stone. Instead, use a dishwasher mounting bracket that anchors the dishwasher to the cabinet boxes on either side, or to the back wall.
How do you secure a dishwasher under a stone countertop?
Use a side-mount, top-mount, or universal dishwasher bracket. The bracket screws into the cabinet face frames (which are wood and drill easily), and the dishwasher’s own mounting tabs then screw into the bracket. This transfers the anchoring from the un-drillable stone to the drillable cabinets.
Do all dishwashers tip over without a bracket?
Many will. A dishwasher with a loaded, open door is front-heavy. Without a bracket securing it to the cabinets or countertop, it can tip forward — a genuine safety hazard. Always secure a dishwasher; never rely on the plumbing connections alone to hold it.
How long does it take to install a dishwasher bracket?
For a standard side-mount bracket, 5 to 10 minutes per the 4-step process — fold the ears, drill pilot holes, screw the bracket to the cabinet, attach the dishwasher tabs. Pilot holes are the step not to skip; they prevent the cabinet frame from splitting.
Does the countertop fabricator install the dishwasher bracket?
Often, but not always. Many stone-countertop installers include dishwasher bracketing as part of the job; others leave it to the appliance installer. Ask your fabricator directly before installation day so the dishwasher doesn’t end up unsecured.
