Kitchen sink cabinet replacement typically costs $600-$2,500, with many standard projects near $1,300. Cabinet size and material, plumbing work, countertop removal, and hidden water damage have the biggest effect on the final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed sink base cabinet | $600 | $1,300 | $2,500 | Standard cabinet and basic installation |
| Cabinet only | $200 | $650 | $1,800 | Stock to semi-custom options |
| Labor and plumbing | $300 | $750 | $1,500 | Removal, fitting, and reconnection |
| Water-damage repairs | $100 | $450 | $1,500 | Depends on damage to adjacent parts |
What a standard sink base cabinet replacement costs
For a common 30- to 36-inch sink base, expect $600-$1,800 installed when the replacement is stock or ready-to-assemble, access is clear, and existing plumbing can be reused. The national middle range is about $900-$1,500. Custom cabinetry, premium finishes, or substantial repairs can push the total to $2,500-$4,000 or more.
Cabinet-only prices are often $200-$900 for stock or semi-custom units and $1,000-$2,500 for custom work. Installation quotes may exclude the sink, faucet, countertop work, and plumbing fees, so the scope matters as much as the headline price. Assumptions: one sink base, standard U.S. labor rates, ordinary access, and no major wall or floor reconstruction. A straightforward replacement is usually far less expensive than a custom cabinet or a project that includes countertop replacement.
How cabinet, removal, and plumbing charges shape the quote
Quotes commonly combine cabinet purchase, demolition, fitting, and plumbing. Ask whether protection, haul-away, finish trim, and reconnection are included. The ranges below are typical U.S. estimates and may overlap when a contractor bundles tasks.
| Quote item | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Stock cabinet | $200-$700 | Per cabinet | Width, construction, finish |
| Custom cabinet | $1,000-$2,500 | Per cabinet | Wood species and design |
| Removal and disposal | $100-$350 | Per job | Fasteners, access, debris |
| Carpenter installation | $250-$700 | Per job | Fit, leveling, trim |
| Plumbing disconnect and reconnect | $150-$500 | Per job | Pipe condition and fixture changes |
Labor may be billed as a fixed project rate or at roughly $50-$100 per hour for a carpenter and $75-$150 per hour for a plumber. Confirm who is responsible for plumbing disconnection before demolition begins.
Why cabinet width and material change the replacement price
Most sink bases are 30, 33, or 36 inches wide; unusual dimensions can require a modified or custom cabinet. A stock 30- to 36-inch unit generally costs less than a custom build, while a cabinet wider than 36 inches, a corner layout, or an integrated organizer can add $200-$1,000 or more.
Particleboard and entry-level plywood cabinets often sit at the lower end of the range. Plywood boxes, hardwood fronts, upgraded finishes, and made-to-order dimensions raise material cost. Measure the cabinet opening, plumbing location, and sink dimensions before ordering. A small size mismatch can add labor or require a replacement unit, so verify measurements rather than relying on the old cabinet label.
When countertop work or plumbing adds more labor
Replacing only the base cabinet is simpler when the countertop can stay in place, but many tops are fastened to the cabinet or are too fragile to lift safely. Detaching and resetting a countertop may add $200-$600; replacing laminate can add about $20-$50 per square foot installed, while stone work commonly costs more and may require a fabricator.
Plumbing costs rise if the drain or supply lines need relocation, corroded shutoff valves need replacement, or the sink and faucet are being changed. Allow another $100-$400 for common valve or connection updates, beyond basic disconnection and reconnection. Keep the sink and plumbing locations unchanged to avoid extra trade work.
How local labor rates shift sink cabinet prices
Labor-intensive metro areas, including parts of the Northeast and West Coast, may price 15%-30% above a national midrange. Smaller markets and rural areas can be 5%-20% lower, although travel charges or limited contractor availability may offset the difference. These are broad comparisons, not fixed regional price lists.
Ask for a written estimate that separates the cabinet, installation, plumbing, countertop handling, and disposal. Compare the same cabinet grade and scope across at least two quotes; a low bid that omits countertop removal or finish repairs may not be cheaper overall. Local labor and what the quote includes can matter more than a modest difference in cabinet price.
Water damage and disposal can create surprise charges
Small repairs to a cabinet floor or trim may add $100-$400. Replacing a larger section of subfloor, correcting a leak, or repairing adjacent cabinets can raise the bill by $500-$1,500 or more, depending on how far moisture has spread. Contractors may charge $75-$200 to investigate or document concealed damage if it is not included in the installation quote.
Removal and haul-away usually cost $100-$350, while difficult access, stairs, or a tight kitchen can increase handling time. A new cabinet should not cover an active leak or wet, softened flooring. Have the leak fixed and the damaged area assessed before the replacement cabinet is installed.
Three project scopes show how totals differ
| Project | Scope and labor | Estimated total |
|---|---|---|
| Basic stock swap | 30-inch cabinet, 4-6 carpenter hours, reuse sink and plumbing | $650-$1,100 |
| Midrange replacement | 36-inch plywood cabinet, 6-9 labor hours, plumber reconnects fixtures | $1,200-$2,100 |
| Custom and repair | Made-to-order cabinet, countertop handling, subfloor repair, 10-16 combined trade hours | $2,500-$4,500 |
These examples assume ordinary residential access and exclude a new sink or faucet unless specified. Use the scope, not just the total, to judge whether two estimates are comparable.
Which choices can lower the cabinet replacement bill
Choose a stock cabinet that matches the existing width and depth, and keep the sink, faucet, and drain in their current positions. If the cabinet box is sound and damage is limited to a door or base panel, ask whether a targeted repair is practical; cabinet repair may cost $150-$600, compared with a full replacement and installation.
Remove stored items and clear the work area before the crew arrives, but leave plumbing disconnection to qualified tradespeople. Request separate prices for countertop handling, disposal, and optional upgrades, then compare written bids with the same materials and tasks. Controlling cabinet size and project scope is usually more effective than choosing the cheapest unit alone.
