Replacing a bathroom door usually costs $250-$900 installed, with many standard projects averaging about $500. The final price depends on whether the door is a slab or prehung unit, whether the frame needs repair, and how much labor, trim, and hardware the job requires.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed replacement | $250 | $500 | $900 | Standard interior door and installation |
| Door slab | $50 | $175 | $400 | Door only, before labor |
| Labor | $125 | $250 | $500 | More for frame work or custom fitting |
| Hardware | $20 | $60 | $150 | Privacy knob or lever and hinges |
Assumptions: U.S. prices for a standard 24- to 30-inch interior bathroom doorway, ordinary access, and midrange materials; local quotes vary.
Typical prices for a standard bathroom door replacement
A basic hollow-core slab installed in an existing, sound frame commonly totals $250-$500. A solid-core door or a prehung unit that replaces the frame often brings the total to $400-$900. Custom sizes, premium finishes, and repairs can push a project above $1,000.
For a straightforward replacement, budgeting around $500 is a reasonable starting point. This assumes a standard-size door, basic hardware, and no major changes to the opening. Prices in high-cost metro areas may run 15%-30% above typical national estimates, while simpler rural jobs can cost less.
What the door, frame, and labor quote includes
Quotes differ in whether they include the door, hardware, disposal, and finish work. A slab uses the existing jamb; a prehung door includes a new frame and is more likely to require trim adjustments and additional fitting.
| Quote item | Typical price | What changes the charge | Usually included |
|---|---|---|---|
| Hollow-core slab | $50-$150 | Finish, size, and style | Door only |
| Solid-core slab | $150-$400 | Weight and surface quality | Door only |
| Prehung door | $150-$500 | Material, jamb, and finish | Door and frame |
| Installation labor | $125-$500 | Fit, frame work, and location | Varies by contractor |
| Hardware and trim | $20-$200 | Lockset, hinges, casing | Often separate |
Ask for materials, installation, disposal, and finishing to be listed separately. Labor may be billed as a flat project rate or at about $50-$100 per hour, with a minimum service charge on small jobs.
How door size and frame condition change the price
Most bathroom doors are 24-30 inches wide and 80 inches tall. An uncommon opening, such as one narrower than 24 inches or taller than 80 inches, can require a special-order door or cutting and fitting, adding roughly $75-$300. A 32-inch door may fit some bathrooms but should not be assumed to match the existing opening.
Frame condition matters just as much. A solid jamb can usually accept a new slab, while water damage, a loose hinge area, or an out-of-square opening may call for carpentry or a prehung replacement. Minor jamb repairs may add $75-$250; rebuilding or resizing the opening can add $300-$800 or more.
Measure the slab and inspect the jamb before comparing quotes. Check width, height, thickness, hinge locations, swing direction, and clearance over the floor. Bathrooms with tile or a new floor may need a door trimmed to preserve clearance without exposing an unfinished edge.
Is a slab cheaper than a prehung bathroom door?
A slab replacement is usually the less expensive choice when the existing frame is straight, secure, and undamaged. The slab itself can cost $50-$400, and installation is often $125-$300. The installer may need to transfer or cut hinge mortises and bore the knob opening, so a door that does not match the old layout can erase part of the savings.
A prehung unit commonly costs $150-$500 for the product, with installed totals around $400-$900. It makes more sense when the jamb is damaged or the opening needs a fresh, square frame. A solid-core door costs more than hollow-core but can offer better sound reduction and a sturdier feel.
Choose the slab route only when the existing frame and hinge layout are usable. Replacing a sound door with another basic hollow-core model may be the lowest-cost option; upgrading to solid core or a decorative panel adds material cost without automatically requiring a full frame replacement.
How long installation takes and what labor covers
Replacing a matching slab often takes 1-3 hours. Installing a prehung unit typically takes 3-6 hours, including leveling, fastening, and adjusting the door. Repairing a damaged jamb, repainting, or correcting an uneven opening can extend the visit to a full day or require a return trip.
Labor usually covers removal, fitting, hanging, and basic adjustments, but painting and extensive trim work may be separate. A contractor may charge $50-$100 per hour or quote $125-$500 for labor, depending on job complexity and minimum fees. Confirm whether the quote includes final latching and swing adjustments.
When removal, trim, or hardware adds to the bill
Removing and hauling away an old door may add $25-$100, though some installers include it. New casing or trim can add $75-$250 for materials and installation. Painting or staining often costs another $75-$250, depending on whether one or both sides are finished and whether the door needs priming.
A basic privacy knob or lever generally costs $20-$75; decorative or keyed hardware can reach $150 or more. A bathroom door should typically use privacy hardware that can be unlocked from outside in an emergency. If the opening contains tile, tight flooring clearance, or damaged plaster, careful cutting and patching may add $50-$300.
Get a written list of exclusions before approving the price. Removal, disposal, casing, painting, and hardware are common reasons a low initial estimate grows after work begins.
Ways to lower bathroom door replacement cost
Keep the existing frame when it is structurally sound, and choose a standard-size slab that matches the current hinge and knob locations. Avoid custom finishes or special-order dimensions unless the opening requires them. Buying the door and hardware together can simplify compatibility, but compare the combined price with the installer’s material quote.
Get two or three itemized estimates based on the same door type and scope. Ask whether the contractor can combine the job with other interior-door work to reduce separate minimum charges. Remove towels, rugs, and nearby furniture before installation, but leave door removal and any cutting to the installer if tools or fit adjustments are involved.
Spend on frame repairs when needed, but skip upgrades that do not solve a real problem. A basic slab replacement can be economical when the jamb is sound; a prehung unit is worth the additional cost when water damage, looseness, or poor alignment would otherwise remain.
