Replacing the bottom of a kitchen cabinet typically costs $150-$600 for one cabinet, with an average near $325. The price depends on panel size, water damage, cabinet construction, access to plumbing, and whether the cabinet needs to be emptied or partially dismantled.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| One cabinet bottom panel | $150 | $325 | $600 | Material and labor for a straightforward repair |
| Panel material | $20 | $55 | $140 | Particleboard, plywood, or finished panel |
| Labor | $100 | $225 | $450 | About 2-5 hours, depending on access |
| Multiple cabinets | $350 | $800 | $1,800 | Several panels, damage, or finish matching |
Typical prices for a single cabinet bottom panel
For one standard base cabinet, homeowners commonly pay $150-$600 to remove a damaged bottom and install a replacement. A simple panel around 24 inches wide and 24 inches deep generally falls near $200-$400 when the cabinet sides and face frame remain sound. A sink-base cabinet or a panel affected by rot can cost more.
Prices assume a small repair using standard plywood or a comparable panel, ordinary access, and no major plumbing relocation. A custom-finished panel, difficult removal, or work in a high-cost metro may push the quote above the typical range. Assumptions: U.S. standard base cabinet, one panel, normal access, no structural rebuild.
A sound cabinet frame usually makes panel replacement far less expensive than replacing the entire cabinet.
What plywood, removal, and labor add to the quote
A contractor’s estimate typically combines panel material, removal and fitting, finish work, and any disposal or access charges. Material is often a smaller share than labor, especially when the old bottom is glued, stapled, or trapped beneath cabinet components.
| Quote component | Typical charge | What changes the price | Common unit |
|---|---|---|---|
| Panel material | $20-$140 | Thickness, grade, finish | Per panel |
| Removal and fitting labor | $100-$350 | Fasteners, damage, access | $50-$100 per hour |
| Sealing or finish matching | $25-$150 | Paint, stain, edge treatment | Per cabinet |
| Disposal and supplies | $10-$75 | Debris volume, sealant, hardware | Per job |
Small jobs may have a minimum service charge of $100-$200 even when the hands-on work takes less than two hours. Ask whether the quote includes removal, panel installation, sealing, and cleanup.
How panel size and water damage change the repair price
Panel dimensions and the extent of damage are major cost drivers. A narrow 18-inch cabinet bottom may need less material than a 36-inch-wide unit, but removal time does not necessarily fall in proportion to size. Replacing several connected bottoms can reduce the per-panel labor cost if the cabinets are cleared and accessible at the same time.
Water damage limited to a removable bottom is usually a routine repair. If swelling reaches the side panels, toe kick, face frame, or floor, carpentry and drying work may add $150-$800 or more. A sink-base cabinet with plumbing openings may add $50-$200 for careful cutting and fitting. Mold cleanup, if needed, is typically quoted separately.
Damage extending beyond the bottom panel can turn a small replacement into a cabinet-box repair.
How long cabinet-bottom replacement takes on site
A straightforward single-panel repair often takes 2-5 hours, including removal, measuring, cutting, fitting, and sealing. Work may stretch to a full day if the panel is difficult to remove, the cabinet must be emptied, or the replacement needs paint or stain to blend with existing surfaces.
Carpenters and cabinet repair technicians commonly charge about $50-$100 per hour, while some price the work as a fixed job. Plumbing disconnection or reconnection can add $75-$250 if a sink trap or supply lines obstruct access. Confirm whether that service is included rather than assuming the cabinet quote covers it.
Clear the cabinet before the appointment to reduce access time and avoid a possible labor add-on.
Plywood repair versus replacing the whole cabinet
Replacing only the bottom is often practical when the cabinet sides, frame, and door remain firm and square. Standard plywood generally costs $20-$80 for a panel-sized piece; higher-grade or prefinished material can cost $60-$140. The installer must choose a thickness that supports stored items and fits the cabinet construction.
A full base cabinet replacement can run roughly $300-$1,200 for the cabinet itself, before countertop work, installation, or plumbing. If the box is badly swollen, moldy, or no longer holds fasteners, patching the bottom may not provide a durable result. Compare the repair quote with the cost of replacing the affected cabinet and any countertop or trim work that removal could disturb.
Repair is usually the lower-cost choice only when the surrounding cabinet structure is still solid.
Regional labor rates and service minimums across the U.S.
Labor prices vary with local wages, contractor demand, and travel distance. Quotes in expensive coastal cities may be 15%-30% above national midrange pricing, while rural markets can be 10%-20% lower; however, limited contractor availability may offset rural savings. These are broad comparisons, not guaranteed local rates.
For a basic single-panel repair, a lower-cost market may quote $150-$350, while a high-cost metro may quote $250-$700. Minimum trip charges matter most on small jobs, so a $125 service call plus materials can make a minor repair cost more per panel than a larger project.
Compare total installed prices, including trip charges, rather than material prices alone.
Extra charges for plumbing access and hidden rot
Removing stored items, disconnecting a disposal or plumbing, and replacing a damaged toe kick can increase the bill. Possible additions include $25-$100 for extra blocking or fasteners, $75-$250 for plumbing access, and $50-$200 for a toe-kick repair. Extensive water cleanup or cabinet-frame reconstruction can exceed these ranges.
Some contractors charge $50-$150 for a site visit, sometimes credited toward approved work. Finish matching may also add time because paint or stain can require drying between coats. A quote should identify excluded work, especially plumbing, mold remediation, countertop removal, and repairs to the floor beneath the cabinet.
Request a written scope that separates the panel repair from any concealed damage or trade work.
Ways to reduce the cabinet-bottom replacement bill
Empty the cabinet, remove loose stored items, and clear the work area before the contractor arrives. If several cabinet bottoms show similar damage, ask for a combined price; one visit can cost less than separate minimum charges. Provide cabinet width, depth, photos, and details about nearby plumbing when requesting estimates.
Choose a durable standard panel that can be sealed or painted instead of paying for a custom finish when the bottom is hidden. Get two or three itemized quotes and compare material thickness, labor, cleanup, and warranty. Avoid covering active leaks with a new panel; fixing the source first can prevent paying for another replacement.
Bundling accessible repairs and resolving the leak before installation are the most controllable ways to limit repeat costs.
