Prepping your kitchen for a countertop installation comes down to three jobs: clear every surface and cabinet near the work area, disconnect anything tied to the old slab, and confirm your final measurements match the template the fabricator already cut. Miss any one of those and the install crew either can't finish the same day or has to reschedule — and shops booking installs for 2026 don't have a lot of slack in the calendar to make that up quickly.
- Clear cabinets and counters completely before the install crew arrives — partial clearing is the #1 cause of delayed installs.
- Confirm sink type (undermount vs. drop-in) so plumbing disconnect is scheduled correctly for 2026 install dates.
- Match appliance cutouts against the fabricator’s final template before install day, not after.
- Plan for a kitchen with no running water and no counter space for the day of install.
- Soares Stone crews need clear floor access from the driveway to the kitchen for carrying stone slabs.
Why this matters
A countertop install date is locked in weeks ahead of time once templating is done, and the crew that shows up has a fixed window to set the slab, seam it, and hook up the sink. If your cabinets are still full or the dishwasher hasn't been disconnected, that window shrinks fast.
Most of what trips homeowners up isn't complicated — it's forgotten. Confirming your measuring for custom countertops details against what actually got templated is the single best way to catch a mismatch before install day instead of on it.
How to prep your kitchen for countertop installation
Work through these in order, starting a few days before your scheduled install:
- Empty every cabinet and drawer near the counters getting replaced. Dishes, small appliances, cleaning supplies — all of it comes out, even from cabinets that look like they won't be touched.
- Clear the counters completely. Coffee makers, knife blocks, fruit bowls, everything. The crew needs a bare surface to remove the old top and set the new one.
- Disconnect the sink and garbage disposal, or confirm your plumber is scheduled to do it before the crew arrives. Undermount sinks typically need to come out before the old countertop can be lifted; drop-in sinks are less involved.
- Remove cabinet doors if hinges sit close to where the template or new slab will be set — this is more common with waterfall edges or oversized islands.
- Disconnect the dishwasher and range if either is tucked tight against the countertop edge. A stove that slides out an inch further than expected can hold up a seam.
- Protect flooring and walkways with cardboard or moving blankets from the entry point to the kitchen. Stone slabs are heavy, and the crew needs a clear, unobstructed path.
- Check appliance cutouts against the fabricator's template. If a new cooktop or sink was ordered after templating, confirm the cutout dimensions still match — this is the single most common cause of a same-day fix.
- Plan for a full day without kitchen water access. Line up meals that don't need the stove or sink, and keep pets and kids out of the work zone.
Why prep requirements vary
Not every kitchen needs the same amount of work before install day. What changes the checklist:
- Sink style — undermount sinks need disconnection and support before the old top comes off; drop-in sinks usually don't.
- Cabinet condition — older cabinets that aren't level need shimming before the new slab goes down, which can add time.
- Existing backsplash tied to the old counter — if tile runs down to meet the countertop, it may need partial removal first.
- Appliance garages or built-ins near the edge — anything bolted close to the counter line adds disconnect steps.
- Second-floor or tight-access kitchens — carrying slabs up stairs or through narrow hallways changes how much clearance the crew needs.
- Whether templating already accounted for appliance changes — a cooktop or sink swapped in after templating is the fastest way to throw off a cutout.
Deciding between quartz and quartzite countertops before templating also matters here — quartzite's natural variation means the slab selection step often happens in person, which can shift your install date if it's skipped early.

Do you need to remove your sink before countertop installation?
Undermount sinks need to be disconnected and often removed before the old countertop comes off, since the sink is mounted to the underside of the slab. Drop-in sinks sit on top of the counter and usually just need the water lines shut off and the sink lifted out, not fully removed from the cabinet. Confirm which type you have with your fabricator before install day so plumbing is scheduled correctly.
How long does a kitchen countertop installation take?
Installation itself typically takes a single work day once the template has already been cut and the slab fabricated. Templating happens separately, usually one to two weeks before the install date, so the full process from first measurement to finished counter spans several weeks — not one visit.
Can you use your kitchen during countertop installation?
No — the sink and water supply are disconnected for the day, and counters aren't usable until adhesive has cured. Plan meals that don't need stovetop or sink access, and expect the kitchen to be out of commission for the day the crew is on site, even if the actual work wraps up by afternoon.
Do cabinets need to be completely empty before templating?
Yes — cabinets and drawers near the work area should be empty before the templating appointment, not just before install. Templaters need clear access to check cabinet height, level, and appliance clearances, and a full cabinet can hide a gap that only shows up once the slab is set.

FAQ
What’s the best way to prep a kitchen before countertop installation?
The best prep is clearing every cabinet and countertop surface completely, then disconnecting the sink and any appliances tied to the old counter. Doing this a day or two ahead of the 2026 install date, not the morning of, avoids last-minute delays.
Do you need to remove your sink before countertop installation?
Undermount sinks usually need to come out before the old countertop is lifted, while drop-in sinks just need water lines disconnected. Ask your fabricator which applies to your setup during the estimate.
How long does a kitchen countertop installation take?
Installation itself typically takes one work day once the slab is fabricated and the template is finalized. The templating-to-install timeline usually runs one to two weeks before that.
Can you use your kitchen during countertop installation?
No, the sink and water supply are shut off for the day and the counters aren’t usable until the adhesive cures. Plan to be without full kitchen access for that one day.
Should you remove backsplash before new countertop installation?
If your existing backsplash tile runs down to meet the old countertop, it may need partial removal before the new slab goes in. Ask your fabricator during templating whether your backsplash is affected.
Is it necessary to unplug appliances before installation?
Yes, disconnect the dishwasher and range if either sits close to the countertop edge, since the crew needs clearance to remove the old slab and set the new one. Appliances further from the work zone usually don’t need to be touched.
How much notice does a fabricator need before install day?
Templating typically happens one to two weeks before the install date, and that’s the window to flag any appliance changes or cabinet issues. Waiting until install day to raise a mismatch usually means a delay.
What happens if my cabinets aren’t level before installation?
Cabinets that aren’t level need shimming before the new slab is set, which the install crew typically handles on site. It’s one of the reasons some installs run longer than the standard one-day estimate.
One last thing
The step homeowners skip most often isn't clearing the counters — it's re-checking appliance cutouts after templating. If you swap a cooktop or sink model between the templating appointment and install day, the cutout the fabricator cut to spec may no longer match. Measure the new appliance against the original spec sheet before install day, not after the slab is already in the truck.
