Painting a 4-bedroom house interior costs $9,000–$15,000 in Melbourne in 2026 for the full scope: walls, ceilings, trim, skirting and doors in two coats of premium paint. Walls-only work in sound condition runs $6,500–$9,000, and a full interior with a dark-to-light colour change can pass $17,000. Interior rates run $20–$60 per square metre, and a 4-bedroom home simply carries more square metres, more trim and usually more storeys than anything smaller.
We’ve painted Melbourne homes since 1987 and carry $20M public liability. The figures below are the real ranges we see across Melbourne quoting, broken down room by room so you can see exactly where the money goes.
Key takeaway
A full 4-bedroom interior costs $9,000–$15,000 in Melbourne in 2026, walls-only $6,500–$9,000. The extra cost over a 3-bedroom home comes from second living areas, extra wet areas and stairwells, not just the fourth bedroom. Prep condition swings any quote by 10–40%, and a colour change adds $800–$1,500.

How much does it cost to paint a 4-bedroom house interior?
A full 4-bedroom interior repaint costs $9,000–$15,000 in 2026, and scope is what places you inside that band. Here’s how the common scopes price out:
| Interior scope | What’s included | Typical cost (2026) |
|---|---|---|
| Walls only | Two coats on walls, minor filling, similar colour | $6,500–$9,000 |
| Walls + ceilings | Walls and ceilings, two coats, standard prep | $8,000–$12,000 |
| Full interior | Walls, ceilings, trim, skirting, doors | $10,000–$14,000 |
| Full interior + colour change | As above with dark-to-light change or extra coats | $12,000–$17,000+ |
Two things about 4-bedroom homes specifically. First, many of them are double storey, and a stairwell void is the hardest interior surface in the house: full-height walls, ladder or platform work, and slow careful cutting-in. Second, 4-bedroom floor plans usually mean two living zones and two or three wet areas, so the trim and door count climbs fast. Both push a 4-bedroom quote up faster than the extra bedroom does.
Key takeaway: Budget $9,000–$15,000 for the full interior. If your home is double storey with a stairwell void, expect the upper half of the range before any colour change is counted.
What does each room cost in a 4-bedroom interior?
Room by room, a 4-bedroom interior runs from about $650 for a standard bedroom to $1,500 for the main living area, with the whole-house trim pass adding $1,000–$2,000. A typical 4-bedroom layout prices out like this, walls, ceiling and trim per room:
| Room | Typical cost (2026) |
|---|---|
| Standard bedroom (x3) | $650–$950 each |
| Master bedroom (with walk-in robe) | $800–$1,200 |
| Main living room | $1,000–$1,500 |
| Second living / rumpus | $900–$1,400 |
| Kitchen and meals area | $800–$1,400 |
| Hallway, entry and stairwell | $700–$1,500 |
| Bathrooms, ensuite and laundry | $900–$1,600 combined |
| Doors, skirting and architraves throughout | $1,000–$2,000 |
Add it up and you land at $9,000–$13,000 for a standard single-storey layout, which is exactly why the full-interior band sits at $9,000–$15,000 once double-storey access, extra prep or a colour change enter the picture.
The stairwell line deserves attention on double-storey homes. A two-storey void with a window above the stairs is platform work, and it can cost as much as a bedroom on its own. Our staircase and stairwell painting guide covers it in detail.
Key takeaway: The fourth bedroom is the cheap part. Second living zones, stairwells and the whole-house trim pass are where a 4-bedroom interior earns its price tag.
What level of preparation does a 4-bedroom interior need?
Prep level swings a 4-bedroom interior quote by 10–40%, which on this size of job is worth thousands. Every proper quote includes baseline prep. What matters is how far past the baseline your walls sit:
| Prep level | What it involves | Effect on price |
|---|---|---|
| Light (baseline) | Wash down, fill nail holes, light sand, spot-prime patches | Included in range |
| Moderate | Crack repair, stain blocking, keying glossy trim and doors | +10–25% |
| Heavy | Plaster repairs, water damage, stripping failing paint | +25–40%+ |
Older Melbourne homes, especially period homes with hard plaster walls, often sit in the moderate band without looking damaged at first glance. Hairline cracking above doorways, settlement cracks in hallways and yellowed gloss trim all take real hours to fix properly. A painter who quotes without walking every room either hasn’t priced the prep or plans to skip it.
Key takeaway: Make the quote itemise prep room by room. “Preparation included” with no detail is how a cheap quote turns into patchy walls within a year.
How long does it take to paint a 4-bedroom house interior?
A full 4-bedroom interior repaint takes about 6–9 working days. That covers preparation, two coats on walls, ceilings and trim, and the drying time between coats. Here’s a typical sequence:
- Days 1–2: Protection, masking, and preparation through the whole house
- Days 3–5: Ceilings first, then walls, first and second coats by zone
- Days 6–8: Trim, skirting, doors and architraves
- Final day: Touch-ups, inspection and cleanup
Walls-only work in good condition comes in closer to a week. Double-storey access, heavy prep, multiple colour changes and high ceilings stretch the window. Most families stay in the house while it’s done; a good crew works zone by zone so bedrooms are back in use each night. Full timelines for every job size are in our painting timelines guide.
Key takeaway: Plan for 6–9 working days and be wary of anyone promising a full 4-bedroom interior in two or three. Either a large crew is coming (fine, ask), or prep and drying time are being cut.
What pushes a 4-bedroom interior quote up or down?
Colour change, ceiling height, storeys and paint condition move a 4-bedroom quote more than anything else. The main levers:
| Cost driver | Effect on price |
|---|---|
| Dark-to-light colour change | +$800–$1,500 (extra coats) |
| High or raked ceilings | +30–40% labour on affected rooms |
| Double storey with stairwell void | Platform work, slower cutting-in |
| Extra coats needed | +25–40% per surface |
| Heavy trim and door count | More cutting-in hours |
As a sanity check, interior painting in Melbourne runs $20–$60 per square metre in 2026, covering prep, two coats and materials. A quote that works back to well under $20/m² on a full interior almost always means skipped prep or a single coat. Consumer Affairs Victoria recommends getting written quotes on identical scope, which is the only way the comparison means anything.
On the honest-savings side: keep the colour close to what’s there, do the whole house in one booking rather than stages, and paint before the current surfaces fail rather than after.
Key takeaway: Flag colour changes and high ceilings before quoting, compare quotes on identical scope, and treat anything under $20/m² for a full interior as a warning sign, not a bargain.

Frequently asked questions
How much does it cost to paint a 4-bedroom house interior?
A full 4-bedroom house interior costs $9,000–$15,000 to paint in Melbourne in 2026, covering walls, ceilings, trim, skirting and doors in two coats of premium paint. Walls-only work in sound condition runs $6,500–$9,000. A dark-to-light colour change, high ceilings or a double-storey layout push the figure toward the top of the range or past it.
Why does a 4-bedroom interior cost so much more than a 3-bedroom?
Because 4-bedroom homes carry more than one extra bedroom. They usually add a second living area, a study, an extra bathroom, more hallway and a bigger kitchen-meals zone, and many are double storey with a stairwell. A 3-bedroom interior runs $6,000–$11,000 while a 4-bedroom runs $9,000–$15,000, and the gap is that extra floor plan, not just one room.
How long does it take to paint a 4-bedroom house interior?
A full 4-bedroom interior repaint takes about 6–9 working days, covering preparation, two coats on walls, ceilings and trim, and drying time between coats. Double-storey homes, stairwell voids, extensive repairs and colour changes stretch the timeline. Walls-only work in good condition is quicker, closer to a week.
How much does preparation add to a 4-bedroom interior quote?
Light prep (washing, filling nail holes, a light sand) is the baseline every quote should include. Moderate prep such as crack repair, stain blocking and keying glossy trim adds 10–25%. Heavy prep, plaster repairs, water damage or stripping failing paint, adds 25–40% or more. On a $10,000 job that swing is worth thousands, so prep must be itemised in writing.
Can I paint a 4-bedroom interior in stages to spread the cost?
Yes, staging by zone (bedrooms first, living areas later) is common and works fine. It costs more in total than one booking because setup, masking and travel happen twice, but it spreads the spend. Keep the same painter and the same named products across stages so sheen and colour match, and get each stage quoted in writing.
