Interior doors are rarely replaced, yet a typical house has about fifteen of them, covering more wall surface than any piece of furniture. Changing their style, colour or hardware can transform a hallway in a few days without touching the walls. Here is how to choose well.
The three main door styles
Shaker panel doors. A simple frame around one or more flat panels. This is the most versatile style: it works in a 1960s bungalow as well as in a new build. A single panel reads modern, while two or five panels feel more classic.
Flat slab doors. A smooth surface with no relief. They give a clean, contemporary look and pair well with thin or minimal trim. They show dents and fingerprints more, especially in a glossy finish.
Traditional moulded doors. Raised panels and decorative mouldings. They suit period homes. In a recent house, they can look like a stage set, especially next to otherwise simple finishes.
The simple rule: pick one style for the whole house and match it to the trim and baseboards. Mixing shaker and moulded doors in the same hallway stands out right away.
Going bold with door colour
White is still the default, but a door painted a soft colour adds character without weighing down the room. Sage green, blue grey, taupe or charcoal all look great on shaker doors.
A few guidelines:
- Paint every door on a floor the same colour. A different colour for each room creates a patchwork look in the hallway.
- Keep casings and baseboards white to make the colour pop, or paint them the same shade for a more modern, enveloping effect.
- Test the colour in the hallway itself, often the darkest area of the house. A shade that looks soft in the store can turn dull without direct light. Our guide on paint colour by room light helps you anticipate that shift.
- Choose a satin or semi-gloss finish. Doors get touched every day, and a matte finish gets dirty and is hard to wash.
Repainting doors calls for good degreasing, light sanding and a bonding primer, especially over old oil-based paint. A painter will often take them off the hinges and paint them flat to avoid drips.
Hardware: the detail that changes everything
Door hardware is seen up close and touched every time you walk by. The handle style should follow the door style:
- Matte black lever on a square rose: crisp and modern, perfect on a white slab door.
- Brushed brass or bronze: warm, beautiful on a colour-painted door.
- Satin nickel: understated, the most neutral choice.
A lever is easier to use than a round knob, which helps children and older adults. Before buying, check the backset (the distance from the door edge to the centre of the handle) so you do not have to drill new holes.
Sliding and pocket doors
When a swinging door blocks a passage or a piece of furniture, a sliding door is a smart fix:
- A pocket door disappears into the wall. It frees up all the space, but the wall has to be opened to install the frame kit. It is a job for a cabinetmaker, best planned during a renovation rather than after.
- A surface-mounted sliding door on a rail goes in without opening the wall. It lets more sound and light through, so it suits an office or closet better than a bedroom.
In natural wood, white oak or walnut, a sliding door becomes a design piece on its own. It pairs well with a pale wood floor; for that choice, see our guide on choosing flooring.
Replace the whole door or just the slab?
There are two options:
- Replace only the door slab. Cheaper, but the new door has to be fitted to the existing frame, with new hinge mortises and lock bore. Older frames are rarely square.
- Install a pre-hung door (with frame). Faster and more precise to install, but the casing has to come off and the trim has to be redone.
For a whole house, pre-hung doors usually give a more uniform result, especially if you are changing the trim too.
Frequently Asked Questions
Which interior door style is the most timeless?
A shaker door with one or two panels. It outlasts trends because it is simple, and it fits almost every type of house, from a bungalow to a new build.
Can you paint interior doors a colour without it looking dated?
Yes, as long as you keep one colour per floor and choose a soft shade like sage green, blue grey or taupe. Bright colours on every door go out of style faster.
What paint finish works best on doors?
Satin or semi-gloss. It resists fingerprints and washes easily. Matte looks better in photos, but it marks quickly on a surface you touch every day.
Can a pocket door go into an existing wall?
Yes, but the wall has to be opened to insert the frame kit, then the drywall and paint redone. The wall must not contain plumbing or ducts, and a load-bearing wall needs proper reinforcement.
Should you change the handles when you change the doors?
It is a good idea. A new handle costs little compared with the door, and consistent hardware throughout the house makes a big difference in the final result.
