Replacing a kitchen sink looks simple on the surface, yet the labor portion of the job can swing widely depending on project scope, home age, and local wage rates. CountBricks—your AI-powered estimating partner—breaks down the variables so residential contractors and homeowners have crystal-clear numbers before demo day.
While faucet style and basin material make headlines, the crew’s time drives most of the project total. On average, labor represents 55-70 % of the overall sink-replacement price on CountBricks residential estimates. Understanding that ratio helps you price work competitively and communicate value to clients.
• Sink configuration (drop-in, undermount, farmhouse)
• Countertop modifications or cut-outs
• Plumbing reroutes and code upgrades
• Disposal, dishwasher, or filter hookups
• Age of shut-off valves and supply lines
• Worksite access and protection requirements
• Permit or inspection coordination
• Metro-area wage benchmarks pulled in real time by CountBricks cost data
1. Straight swap (same size, no countertop work): 2-3 labor hours
2. Undermount conversion with countertop trimming: 4-6 labor hours
3. Farmhouse retrofit with cabinet reinforcement: 6-9 labor hours
Multiply those hours by the prevailing rate your crew commands, then add taxes, insurance and overhead. CountBricks does this automatically when you speak the scope into our mobile app, giving you an instant, line-item labor total.

Last quarter a CountBricks partner contractor tackled a 12-unit townhouse refresh that included swapping every kitchen sink. By leveraging our AI blueprint takeoffs, the team identified identical cabinet dimensions across units and standardized the installation sequence.
• Pre-fabricated plywood cut-out templates eliminated field measuring delays
• Voice cloning of the first unit’s scope auto-generated labor lines for the remaining eleven
• Real-time wage tracking flagged a mid-project rate increase, allowing the GC to lock in subcontractor pricing early
The result: average labor dropped from 4.5 hours per sink to 3.7, saving 9.6 crew hours across the project—an 18 % improvement that translated into $640 in preserved margin.
• Batch similar tasks—removals first, installs second—to maintain momentum
• Keep consumables (silicone, supply lines, putty) on a rolling cart within arm’s reach
• Use CountBricks mobile timers to compare estimated vs actual task durations in real time
• Debrief daily; feed variance data back into CountBricks so future estimates auto-adjust
