Are cavity sliding doors worth it?

For walk-in robes, butler's pantries, small bathrooms and tight corridors, cavity sliding doors are worth it — they save significant space and look clean (the door disappears into the wall when open). The cost ($300–$800 per door including the cavity) is moderate. However, cavity sliders must be planned during construction — they can't be retrofitted without rebuilding the wall.

Can I add sliding doors after construction?

Surface-mounted sliding doors (barn doors on a track) can be retrofitted — they slide along the wall surface on an exposed track. However, they take up wall space when open and have a more rustic/industrial look. Cavity sliding doors (sliding into the wall) cannot be retrofitted without demolishing and rebuilding the wall.

Do sliding doors seal as well as hinged doors?

Sliding doors don't seal as tightly as hinged doors — there's typically a small gap around the edges for the door to slide. This means slightly more sound and draught transfer than a hinged door. For rooms where sound isolation is critical (media rooms, bedrooms), hinged doors are generally better. For robes, pantries and utility rooms, the sealing difference is negligible.

Key Takeaways

Hinged doors are standard and provide full access; they require swing clearance
Sliding doors save space — no swing clearance needed — but provide partial access
Cavity sliding doors (sliding into the wall) are the cleanest option; require wall cavity planning
Barn-style sliding doors (surface-mounted) are a design feature but take up wall space
Sliding doors are recommended for small rooms, robes, pantries and tight corridors

Most internal doors in Australian homes are hinged — they swing open on hinges mounted to a frame. But sliding doors can be a practical and stylish alternative in certain situations, saving space that would otherwise be needed for door swing. Understanding when to choose sliding vs hinged helps you optimise your home's layout.

Hinged Doors (Standard)

Full access — the entire doorway is accessible when the door is open
Good sealing — closed doors seal well against the frame, reducing sound and draught transfer
Standard cost — the most affordable option; included in most builder base prices
Requires swing clearance — the door needs wall space to swing open; can affect furniture placement

Sliding Doors

Saves space — no swing clearance needed; ideal for small rooms, tight corridors and areas where furniture would be hit by a swinging door
Partial access — only half the doorway is accessible at any time (one panel slides over the other or over the wall)
Cavity sliding — the door slides into the wall cavity; the cleanest option; no visible door when open; requires wall cavity planning during construction
Surface sliding (barn door) — the door slides along the wall surface on a track; a design feature; takes up wall space when open

Where Sliding Doors Work Best

Walk-in robes and wardrobes — sliding doors save space in bedrooms; cavity sliders are the cleanest
Butler's pantries — cavity sliding doors hide the pantry when not in use without swinging into the kitchen
Small bathrooms and ensuites — where a hinged door would hit the vanity or toilet
Powder rooms — where space is tight and a swinging door would obstruct the corridor
Laundries — where a hinged door might hit the washer, dryer or cabinetry
Home theatres / media rooms — sliding doors for sound isolation without swing clearance

Watch Out

Cavity sliding doors require wall cavity planning during construction — the wall frame needs to accommodate the sliding track and door panel. If you want cavity sliders, tell your builder during pre-construction. Retrofitting cavity sliders after construction is very expensive — it requires demolishing and rebuilding the wall. Surface-mounted barn doors can be retrofitted, but they take up wall space.

Cost Comparison

Example Door Type Costs

Door Type	Example Cost
Standard hinged door	Standard inclusion
Surface sliding door (barn style)	$200–$600 per door
Cavity sliding door (incl. cavity)	$300–$800 per door
Double cavity sliding doors	$600–$1,500

Real-world examples only. Cavity sliding doors include the cavity (wall frame modification) and track. Costs vary by builder and door size.

Questions to Ask Your Builder

Does the builder include cavity sliding doors for robes and pantries, or are they an upgrade?
Which rooms would benefit from cavity sliders — walk-in robes, butler's pantry, small bathrooms?
Can I add surface-mounted barn doors later, or should I plan cavity sliders now?
Do sliding doors seal as well as hinged doors in the rooms I'm considering?

Common Mistakes to Avoid

Not planning cavity sliding doors during pre-construction — they can't be retrofitted without rebuilding walls
Using hinged doors in small bathrooms where the door hits the vanity or toilet
Forgetting sliding doors in walk-in robes — the swing clearance wastes usable space
Choosing surface barn doors where cavity sliders would be cleaner — visible track and wall space used

Builder Tips

Cavity sliders are ideal for walk-in robes, butler's pantries, small bathrooms and tight corridors
Plan cavity sliders during pre-construction — the wall frame must accommodate the track and door
For media rooms or bedrooms where sound isolation matters, hinged doors seal better than sliding
Surface barn doors can be retrofitted but take up wall space — use them when cavity sliders aren't possible
