What Actually Eats Your Time on a Cabinet Install
I have done enough kitchen installs to know that the cabinets themselves are only half the story. Here is where the hours really go:
- Checking level and plumb first. Spend 30-45 minutes snapping lines, checking the floor for high and low spots, and finding studs before you set a single box. This front-end investment saves hours of shimming later.
- Corner cabinets. Blind corners and lazy susans take 2-3x longer than a standard box. Budget 90 minutes for a blind corner base instead of the usual 45.
- Sink base plumbing cutouts. Cutting the back panel for supply lines, drain, and disposal wiring adds 20-30 minutes to that one cabinet.
- Appliance panels and fillers. Scribing a dishwasher panel or end panel to an out-of-plumb wall is slow, precise work. Each filler strip adds about 18 minutes.
- Crown molding. Compound miters on top of cabinets require patience. The corners never line up perfectly because the cabinets are never perfectly straight. Allow 9 minutes per linear foot including caulk.
Typical Kitchen Install Timeline
| Kitchen Size | Cabinet Count | Stock (2-person) | Custom (2-person) |
|---|---|---|---|
| Galley / Small | 8-12 | 1 day | 1.5-2 days |
| Average Kitchen | 15-20 | 1.5-2 days | 2.5-3 days |
| Large / L-Shape | 22-30 | 2-3 days | 3-4 days |
| Custom Estate | 30-40+ | 3-4 days | 5-7 days |
Timelines include demo of old cabinets, install, and basic trim. Countertop templating happens after cabinets are set but is not included here. Add 0.5-1 day for crown molding on a full kitchen.
How to Bid Cabinet Installation Labor
Whether you charge hourly or per-cabinet, you need to know your hours to stay profitable. Here is how I approach a cabinet bid:
- Count every box. Get the cabinet layout drawing or count them on the floor plan. Separate base, upper, and tall units.
- Multiply by your rate per type. Use the table above as a starting point. Adjust up for old houses with bad walls or down for new construction with clean drywall.
- Add demo time. If ripping out old cabinets, add 20-25 minutes per box plus 1-2 hours for countertop removal and haul-out.
- Add trim and hardware. Crown, fillers, end panels, and drilling hardware all add up. A typical 20-cabinet kitchen needs 3-5 hours for these extras.
- Pad 10-15%. Things go sideways. A stud is missing. A box is damaged. The floor drops half an inch at the sink. Build in a buffer so you are not eating hours.
Cabinet Installation Labor Guide
Rule-of-thumb labor hours for kitchen cabinet installation, sourced from field experience and industry data.
How many hours does a kitchen cabinet install take?
A typical kitchen with 15-20 cabinets requires 16-30 total labor hours depending on cabinet complexity. Stock cabinets from big-box stores install at 30-45 minutes per upper and 45-60 minutes per base. Custom cabinets require 75-120 minutes per box because of scribing, shimming, and precise gap control. A 2-person crew finishes a stock kitchen in 1.5-2 days. Custom runs 2.5-3 days for the same layout.
Key Takeaways
- Stock cabinets: 0.5-0.75 hrs per box (upper/base avg)
- Semi-custom: 0.75-1.0 hrs per box
- Custom: 1.25-1.5 hrs per box
- Add ~21 min per cabinet for old cabinet demolition
- Setup and layout adds 1.5 hrs + 6 min per cabinet
What is the labor cost to install kitchen cabinets?
Cabinet installation labor costs $50-$85 per hour for a skilled finish carpenter in 2026. The total depends on cabinet count and complexity. A stock install of 18 cabinets runs about $1,500-$2,500 in labor. Semi-custom runs $2,000-$3,500. Custom cabinetry installation labor costs $3,000-$5,000+ for the same kitchen because per-cabinet time nearly doubles.
Key Takeaways
- Carpenter rate: $50-$85/hr (national average 2026)
- Stock kitchen labor: $1,500-$2,500 for 18 cabinets
- Custom kitchen labor: $3,000-$5,000+ for 18 cabinets
- Does not include countertop fabrication or plumbing reconnect
What adds time to a cabinet installation?
Several factors can push a cabinet install well beyond the standard per-box estimate. Out-of-level floors and walls are the number one time killer. Other common slow-downs include blind corner cabinets, sink base plumbing cutouts, appliance panels that need scribing, and crown molding with compound miters. Old homes with plaster walls or multiple layers of flooring consistently take 20-30% longer than new construction.
Key Takeaways
- Out-of-plumb walls: shimming every box adds 10-15 min each
- Blind corner cabinets: 2-3x longer than standard boxes
- Sink base cutouts: +20-30 min for plumbing/disposal access
- Crown molding: ~9 min per linear foot of cabinet run
- Old houses: budget 20-30% more time than new construction

Frequently Asked Questions
How long does it take to install kitchen cabinets?
A typical kitchen with 15-20 cabinets takes 1-3 days for a 2-person crew. Stock cabinets install fastest at roughly 45 minutes per base cabinet and 30 minutes per upper. Custom cabinets take 90-120 minutes per base because every box needs scribing, shimming, and precise alignment. Add half a day for demolition of old cabinets.
How many labor hours per cabinet should I estimate?
Rule of thumb: base cabinets take 0.75-1.5 hours each, uppers take 0.5-1.25 hours, and tall pantry units take 1-2 hours. The range depends on whether you are installing stock, semi-custom, or custom cabinets. Stock boxes bolt together with minimal fitting. Custom requires scribing to uneven walls, shimming for level and plumb, and more precise alignment between boxes.
How much does cabinet installation labor cost?
Cabinet installation labor runs $50-$85 per hour for a skilled carpenter, or roughly $75-$200 per cabinet installed. A full kitchen with 18 stock cabinets typically costs $1,500-$2,500 in labor alone. Custom cabinet installs run $3,000-$5,000+ for the same count because the per-cabinet time is nearly double.
Do I need two people to install cabinets?
You can install base cabinets solo, but upper cabinets almost always need two people. Wall cabinets weigh 30-80 lbs loaded and must be held in position while fastened to studs. Solo installers use a cabinet jack or a temporary ledger board screwed to the wall, but a second set of hands is faster and safer. Budget for a 2-person crew.
How long does it take to remove old kitchen cabinets?
Old cabinet demolition takes about 20-25 minutes per cabinet on average. A full kitchen tearout of 18-20 cabinets takes 6-8 hours for one person, including disconnecting plumbing at the sink base, removing countertops, unscrewing boxes from the wall, and hauling debris. Budget an extra hour for dumpster trips or trailer loading.
What slows down a cabinet installation?
The biggest time killers are: out-of-level floors and walls (requires shimming every box), plumbing and electrical in the way, old tile or flooring that creates uneven surfaces, and tight corners that need custom fillers. I have seen a "simple" install double in time because the walls were 3/4 inch out of plumb across a 10-foot run. Always check level and plumb before you start setting boxes.
Does crown molding on cabinets take long?
Crown molding on top of cabinets adds about 9 minutes per linear foot of cabinet run. A 20-foot kitchen perimeter takes roughly 3 hours total. The time includes measuring, cutting compound miters, fitting inside and outside corners, nailing, and caulking. If the cabinets are not perfectly level across the top, you will spend extra time shimming or scribing the crown to hide gaps.
What is the difference between stock and custom cabinet install time?
Stock cabinets install 40-50% faster than custom. Stock boxes are standardized sizes (12", 15", 18", 24", 30", 36" widths) that bolt together quickly with minimal fitting. Custom cabinets are built to exact dimensions for your space, which means every box needs careful shimming, scribing to walls, and precise gap control between units. A kitchen that takes 1.5 days with stock takes 2.5-3 days with custom.
