Quick answer: Below is a real interior painting estimate, anonymized, for a 3-bedroom 1,800 sq ft single-family home in a mid-cost suburban market. Total: $5,640 for a whole-house repaint including walls, ceilings, trim, doors, and closets, with a color change to lighter neutrals. The estimate is broken room-by-room so you can see exactly where the labor goes and why bathrooms cost more per square foot than bedrooms.

“Interior estimates feel simple because the surface is forgiving (no weather, no ladders). They’re actually where painters most often lose money — bathrooms eat hours, color changes need an extra coat, and customers sneak the closet into the ‘you’ll do that too, right?’ conversation. This example shows what to charge for, every time.”

Why bathrooms cost more per square foot than bedrooms
- Fixtures. Toilet, vanity, tub, shower surround — all need masking and careful cut-in.
- Humidity-warped surfaces. Bathroom corners need more sanding and patching than dry-room corners.
- Working around plumbing. Hand brushwork behind toilets and around pedestal sinks is slow.
- Mildew-resistant paint. Most painters use kitchen/bath formulations (slightly more expensive per gallon).
- Smaller surfaces mean less “rhythm.” A bedroom wall is a smooth 8×12 ft surface a painter can roll fast. A bathroom wall is broken up by mirrors, towel bars, and the medicine cabinet — constant stops and starts.
Your interior estimate in 4 minutes.
PaintPricing’s calculator handles the per-room math automatically — bathrooms get the higher labor rate, bedrooms get the standard rate, closets get the per-room toggle. Same level of detail as this example, no spreadsheet wrangling.
The same job in three customer scenarios
Scenario A: Walls only, no ceilings, no closets ($3,800)
Same home, lighter scope. Skip ceilings (still in decent shape), skip closets, walls + trim only.
Scenario B: Walls + ceilings, no closets ($4,640)
Add ceiling repaint, skip closets. Most common compromise.
Scenario C: Full scope as above ($5,640)
Walls + ceilings + closets + trim everywhere. The customer wants the home to feel completely fresh.
Showing scenarios A/B/C in your estimate gives the customer an instant way to negotiate scope without you re-doing the math. It also positions you as the painter who’s thought through the options — usually a win against painters who only quote one number.
Per-room benchmarks to sanity-check your own estimates
- Standard bedroom (12×13, 8 ft ceilings, walls + ceiling, doors + 1 window): $480–$760 in mid-cost markets.
- Master bedroom (14×16, +trim, +closet): $720–$1,100.
- Bathroom (walls only): $260–$420 (note: higher per-sq-ft than bedrooms).
- Open living/dining (16×20, +trim): $880–$1,400.
- Kitchen walls only (no cabinets): $340–$520.
- Hallway + foyer: $240–$420 (higher if cathedral ceilings).
Adjust 30–50% up for high-cost metros (LA, Bay Area, NYC, Boston, DC) and 20–30% down for rural / low-cost regions.
Common mistakes on interior estimates
- Same labor rate for every room. Bathrooms run 30–50% slower than bedrooms per square foot.
- Forgetting closets. Most customers assume closets are included. If they’re not, write “closet interiors not included” explicitly.
- Not pricing color changes. A color change costs ~15% more (tinted primer + heavier coverage). Flag it as a line item.
- Skipping ceilings without explicit customer agreement. Ceilings yellow with age — new wall paint will make old ceilings look worse. Tell the customer this in writing.
- One total instead of room-by-room. Loses negotiation flexibility; customers default to “can you do it for less” instead of “can we drop a room.”
When this example stops fitting your job
Adjust for: home age (pre-1978 needs lead-paint testing, +$200–$500), wall condition (heavy patching = +$300–$800), high ceilings (10+ ft adds 20% per affected room), accent walls (+$100–$200 per wall), occupied vs vacant home (occupied is 15–25% slower because of working around furniture). For your specific job, PaintPricing’s free calculator applies these multipliers automatically. Same level of detail as this example, 4 minutes from your phone.
Frequently asked questions
How much does it cost to paint a 1,800 sq ft house interior?
In 2026, a full interior repaint on a 1,800 sq ft 3-bedroom home runs $4,500–$8,500 in mid-cost markets, depending on scope (walls only vs walls + ceilings + closets) and whether there’s a color change. The example above is $5,640 for whole-house including ceilings, closets, and trim with a color change.
Why is the bathroom more expensive per square foot than the bedroom?
Bathrooms take 30–50% more labor hours per square foot because of fixtures (toilet, vanity, tub), humidity-warped corners, masking around tile, and the constant stops-and-starts of bathroom brushwork. The example above shows a bathroom at 1 hour per 39 sq ft and a bedroom at 1 hour per 53 sq ft.
Should closets be included in an interior painting estimate?
Yes, if the customer expects them. Closet interiors are often skipped from low bids to save 4–8 hours of labor. If your estimate doesn’t flag whether closets are included or excluded, specify in writing. Most customers assume closets are included; surprise exclusions cause disputes.
How much paint do I need for a 1,800 sq ft interior repaint?
13–16 gallons of wall paint plus 3–5 gallons of trim paint plus 3–5 gallons of ceiling paint for a 2-coat application on a 1,800 sq ft 3-bedroom home with a color change. Use 350 sq ft per gallon for new drywall, 300 sq ft per gallon for older homes with patched walls.
How long does an interior painting job take?
5–8 working days for a 1,800 sq ft 3-bedroom whole-house interior with a 2-painter crew. The example above uses 6 days. Add 1–2 days for cabinet work, color changes throughout, or heavy prep. The customer staying in the home (vs vacant) adds 10–20% to the schedule because of furniture-shuffle time.
Should the interior estimate be priced per room or as one total?
Both. Show the customer the room-by-room breakdown plus the total. The breakdown lets them negotiate by dropping rooms; the total gives them the simple number they want to compare with other bids. Painters who only show one total lose negotiation flexibility and get pushed on price.
Do I need to repaint the ceiling if the walls are repainted?
Recommended but not required. New wall paint makes old ceilings look yellower than they already are. The example above includes ceilings ($800 of labor) for this reason. If the customer wants to save money, ceilings can be skipped, but write “ceilings not included; existing ceiling color may look different next to new wall paint” explicitly in the scope.
How much should a 10% deposit be on an interior painting estimate?
10% of the total contract value. On the $5,640 job above, that’s $560. Most U.S. states cap deposits at 10% or $1,000 (whichever is less) for residential work. Some painters waive deposits for repeat customers or jobs under $1,500. Never accept a painter asking for 50% upfront — it’s illegal in many states and a red flag everywhere.

2026 industry benchmarks for sanity-checking
Whether you’re writing the estimate or reading one, the numbers below are the 2026 industry baselines for U.S. residential painting. Use them to cross-check anything that feels off — on either side of the bid.
Pricing reference (mid-cost markets, 2026)
- Interior repaint, walls only: $1.50–$2.80 per sq ft (floor area), 2 coats.
- Interior repaint, walls + ceilings + trim: $3.00–$5.00 per sq ft.
- Exterior repaint, vinyl or Hardie siding, moderate prep: $3.00–$5.00 per sq ft.
- Cabinet painting (per door): $75–$110 per door, $35–$55 per drawer front.
- Deck staining: $2–$4 per sq ft including light cleaning and 1 coat.
- High-cost metros (LA, NYC, Bay Area, Boston, Seattle, DC): multiply above by 1.4–1.6x.
- Rural / low-cost regions (rural Midwest, Deep South): multiply by 0.70–0.85x.
Timeline reference (working days, 2-painter crew)
- Single room repaint: 1–2 working days.
- Interior whole-house, 1,500–2,000 sq ft: 4–6 working days.
- Exterior whole-house, 2-story 2,000 sq ft: 10–14 working days, weather permitting.
- Cabinet kitchen repaint (22 doors): 5–8 working days plus 5–7 days enamel cure.
Business-side benchmarks for painters
- Gross margin target: 30–50% on residential work, 25–35% on commercial.
- Loaded labor cost: 1.4–1.8× wage rate (covers payroll tax, workers comp, insurance, overhead).
- Material vs labor split: Materials are 15–25% of direct cost on interior, 20–30% on exterior.
- Standard deposit: 10–15% on residential under $3,000; phased progress payments on jobs over $5,000.
If a bid you’re looking at — whether you’re writing it or reading it — is more than 25% outside these ranges, dig into why. Either the scope is different than you think, or the painter is in a different cost environment, or someone’s math is off. Use PaintPricing’s free calculator to generate a tailored estimate against these benchmarks in about 4 minutes.
