A door for a room typically costs $150-$700 installed, depending on whether the job uses a basic prehung or slab door, the material, and the condition of the opening. A standard interior door itself is often $50-$350; custom sizes, upgraded hardware, painting, and frame repairs increase the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door slab only | $50 | $175 | $500 | Standard hollow-core to solid wood |
| Prehung door unit | $100 | $275 | $700 | Includes door in a frame |
| Installation labor | $100 | $250 | $600 | Higher for repairs or custom fitting |
| Typical installed project | $150 | $400 | $1,200 | One standard interior doorway |
What a standard bedroom door costs installed
For a common 30- or 32-inch-wide interior doorway with a 6-foot-8-inch height, a basic hollow-core replacement generally totals $150-$400. A solid-core door or a new prehung unit usually brings the installed price to $300-$700. Custom wood, glass panels, or a nonstandard opening can raise the total to $700-$1,200 or more.
Most standard replacements land near $250-$500 when the existing frame is sound. These estimates assume ordinary access and midrange U.S. labor rates; urban markets and high-cost regions may run 15%-30% higher. Assumptions: standard interior opening, no electrical or structural work, basic finish.
How the slab, frame, and labor appear on a quote
A quote may price a door slab alone or a prehung unit that includes the jamb and hinges. Confirm which option is included, since a slab replacement can require careful trimming and hinge preparation, while a prehung installation involves removing and resetting the frame.
| Quote component | Low | Average | High | Typical basis |
|---|---|---|---|---|
| Hollow-core slab | $50 | $100 | $200 | Per door |
| Solid-core or wood slab | $150 | $275 | $500 | Per door |
| Prehung door unit | $100 | $275 | $700 | Per unit |
| Installation labor | $100 | $250 | $600 | Per opening |
| Hardware and trim | $20 | $75 | $250 | Per opening |
Labor often accounts for as much as the door itself on a straightforward replacement. Carpenters commonly charge $50-$100 per hour, with a minimum service charge of roughly $100-$200. Painting, disposal, and frame repairs may be separate line items.
When 30-inch sizing and frame condition change the price
Common widths include 24, 28, 30, 32, and 36 inches, with 30- and 32-inch doors widely used for bedrooms. A standard-size slab is less expensive and easier to fit than a custom width or height; custom orders can add $100-$400 to the door price and may take several weeks.
The opening condition matters too. A sound, square jamb may need only minor adjustments, while a warped frame, damaged drywall, or uneven floor can add $100-$500. Solid-core doors are heavier than hollow-core models and may require stronger hinges or additional labor, typically adding $50-$200 to the project.
Measure the door slab, jamb, and opening before comparing prices. Measure width and height in several places, and check the swing direction and hinge locations. A quote based only on the nominal door size may exclude fitting work if the actual opening is out of square.
How long installation takes and what labor covers
Replacing a slab in a usable frame often takes 1-2 hours; installing a prehung door may take 2-4 hours. Removing trim, correcting an uneven opening, or installing several doors can extend the visit. Labor estimates of $100-$250 are common for uncomplicated work, while complex fitting or finish carpentry can reach $300-$600.
Ask whether the labor charge includes removal, hardware installation, and cleanup. Some contractors price by the opening rather than by the hour. A per-door estimate makes it easier to compare bids, but the scope should identify painting, trim replacement, and disposal as included or excluded.
Three room-door quotes for different project scopes
| Example | Materials | Labor and extras | Estimated total |
|---|---|---|---|
| Hollow-core slab swap | $80-$150 door and $25-$60 hardware | 1-2 hours; $100-$200 labor | $205-$410 |
| Solid-core prehung bedroom door | $250-$450 unit and $40-$100 hardware | 3-4 hours; $200-$350 labor | $490-$900 |
| Custom-width wood door | $400-$800 door and $75-$150 hardware | 4-6 hours; $300-$600 fitting | $775-$1,650 |
These examples assume one opening and standard access, not major wall or frame reconstruction. A quote may also include $25-$100 for disposal or $50-$200 for painting, depending on local rates and the amount of finish work.
Removal, paint, and hardware charges beyond the door
Old-door disposal can cost $25-$100, and new casing or trim may add $50-$250 per opening, including installation. Painting typically costs $75-$200 per door when both sides and edges are finished; color changes or extensive sanding can raise that amount. A basic knob may cost $15-$50, while privacy locks or decorative hardware can cost $30-$150.
Check whether the estimate includes both sides of the door, casing, and disposal. If the existing hardware is compatible and in good condition, reusing it may avoid a replacement charge. Painting before installation can be practical, but confirm who handles final touch-ups.
Slab replacement versus installing a new prehung unit
A slab-only replacement is usually the lower-cost choice when the existing jamb is straight, solid, and matches the new door’s dimensions and hinge layout. It can save $50-$250 in material and frame work, though custom trimming or hinge mortising may reduce the savings.
A prehung unit is often worth the added cost when the frame is cracked, warped, or badly out of square. It replaces the door and jamb together, usually for $100-$700 before labor. Frame condition, rather than the door’s appearance alone, should determine which option is priced.
Ways to lower the cost of a room-door replacement
Keep the existing frame when it is sound, select a standard-size hollow-core or solid-core door, and avoid changing the swing or opening dimensions. Reusing suitable knobs and hinges can also reduce material charges. If several doors need replacement, request a combined quote; shared travel and setup may lower the labor cost per opening.
Compare itemized estimates for the same door type and work scope. Confirm measurements, hardware, trim, paint, disposal, and frame repairs before choosing a bid. A low price that excludes fitting or finishing may not be cheaper once those charges are added.
