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.
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.
