When planning an interior refresh, one question pops up time and again: How long does interior painting take? Whether you are hiring a professional or tackling a DIY project, knowing the timelines helps you budget, plan, and set realistic expectations.
This guide breaks interior painting down room by room. For the complete overview of every project type, see our main guide to how long it takes to paint a house.
In this comprehensive guide, we break down how long to repaint a room, including factors that influence painting time, preparation tips, and a room-by-room breakdown so you know exactly what to expect.
Why Knowing Painting Timelines Matters
Painting a room is not just about opening a tin of paint and rolling it onto the walls. It involves:
- Preparation – moving furniture, repairing cracks, sanding surfaces.
- Priming – especially if you’re covering dark colours or damaged walls.
- Applying multiple coats – most walls need at least two coats for an even finish.
- Drying times – skipping this step leads to peeling and uneven coverage.
Understanding these steps ensures your project runs smoothly without last-minute surprises.
Factors That Affect How Long Interior Painting Takes
Before we dive into the room-by-room breakdown, let’s look at the key factors that influence the overall timeframe:
1. Room Size and Layout
- Larger rooms take more time simply because there’s more wall space to cover.
- Open-plan layouts require more precision and cutting in, which slows down the process.
2. Condition of the Walls
- Damaged walls require filling, sanding, and sometimes even re-plastering.
- Wallpaper removal or textured walls will add extra hours or even days.
3. Colour Changes
- Painting over a dark shade with a lighter colour? Expect an additional coat or two.
- Bright or bold colours usually require more coverage than neutral shades.
4. Number of Coats
- Standard walls need two coats, but some surfaces or colours may need three.
- Add extra time for ceilings, trims, and doors.
5. Drying Times Between Coats
- Water-based paints usually need 2–4 hours between coats.
- Oil-based paints can take 6–8 hours or longer to dry.
6. Professional vs DIY
- Professionals work faster and more efficiently.
- DIY projects often take longer due to limited tools and experience.
How Long Does It Take to Paint a Room? Room-by-Room Breakdown
Now, let’s answer the question everyone asks: How long to repaint a room? Here’s an in-depth look.
Bedroom – One to Two Days
Bedrooms are moderate in size, making them one of the quicker spaces to paint.
Estimated Time:
- DIY: 1.5–2 days
- Professional: 1 day
Why?
- Most bedrooms have fewer architectural details and less furniture than living rooms.
- Prep work includes moving beds and wardrobes, taping edges, and protecting flooring.
Tips for Speed:
- Remove or cover all furniture before starting.
- Use extension rollers for faster wall coverage.
Bathroom – Half a Day to One Day
Bathrooms may be small, but they require precision.
Estimated Time:
- DIY: 1 day
- Professional: 4–6 hours
Challenges:
- High moisture areas need mould-resistant primers.
- Tight corners and built-in fixtures make painting tricky.
Pro Tip:
Always clean surfaces thoroughly to remove soap residue or mildew before painting.
Kitchen – One to One and a Half Days
Kitchen painting is time-consuming due to cabinets, tiles and appliances.
Estimated Time:
- DIY: 1.5–2 days
- Professional: 1–1.5 days
Key Steps:
- Degreasing walls is essential before priming.
- High-adhesion primers ensure paint sticks to tricky surfaces.
Extra Time Needed For:
Painting cabinets or backsplashes will add a full day or more.
Living Room – One to Two Days
Living room painting often takes the longest because of size and layout.
Estimated Time:
- DIY: 2–3 days
- Professional: 1–2 days
Why It Takes Longer:
- Larger wall areas, big windows, and decorative trim add complexity.
- Open layouts often require blending into dining areas or hallways.
Efficiency Tip:
Use long-handled rollers for high ceilings and invest in quality drop cloths.
Hallways and Stairwells – One to Two Days
Small but tricky! Narrow layouts and high ceilings make hallways a challenge.
Estimated Time:
- DIY: 1–2 days
- Professional: 1 day
Complications:
- High traffic areas often need extra prep for scuff marks.
- Stairwells require ladders or scaffolding for safe access.
Pro Tip:
Choose durable, washable paint for these high-use areas.
