A practical laundry room is often around 5 to 8 square metres, although a smaller space can work well when appliances, storage and benchtops are planned efficiently. The right size depends less on achieving a specific floor area and more on leaving enough room to load appliances, use the sink, store household items and move comfortably without wasting valuable space elsewhere in the home.
Key Takeaways
- Around 5–8 m² works well for many dedicated laundries.
- Compact laundries can work with efficient layouts.
- Appliance clearances matter as much as floor area.
- Vertical storage makes small laundries more practical.
- Design the room around your household’s washing routine.
How Big Should a Laundry Room Be?
A laundry room should be at least 4 to 6 square metres for a standard separate room, though compact European laundries can function in as little as 1.2 to 2 square metres when the layout uses stacked appliances and vertical storage intelligently.
The right size is not a universal number. It comes from the household’s laundry load, the appliances being used, how much storage is needed, and whether the room serves secondary functions like a mudroom or drying area.
A room that is too small restricts movement, limits storage, and makes daily use genuinely uncomfortable. A room that is too large in a home where the budget could be spent elsewhere is not always the right answer either.
The most useful way to approach the size question is by starting with the layout type that matches the available floor area, then working out what that layout can realistically accommodate.
Laundry Room Sizes by Type
The three laundry types used across Melbourne homes each suit a different floor area range, and each comes with distinct limits on what can be included and how the space functions.
Compact European Laundry: 1.2 to 2 Square Metres
A European laundry fits into an alcove or deep cupboard, typically 600 to 900mm deep and 1.2 to 2 metres wide. The appliances stack vertically, a narrow bench may be included above or beside the machines, and the space is concealed behind bifold or sliding doors.
This format works well in apartments, townhouses, and homes where a dedicated laundry room is not available. It handles the functional requirements of washing and drying but offers limited storage and no folding space. The household must plan to fold laundry somewhere else.
Standard Separate Laundry: 4 to 6 Square Metres
A 4 to 6 square metre room is the practical standard for a dedicated separate laundry in a Melbourne home. It accommodates side-by-side or stacked appliances, a full-width folding bench, a laundry tub, and overhead storage running the length of the room.
This size suits most households doing three to six loads of washing per week and is the configuration that laundry room ideas for storage and function are most commonly designed around.
Large Utility Room: 7 Square Metres and Above
A laundry room at 7 square metres or more allows the full utility room configuration: generous bench runs on multiple walls, a deep trough, hanging space for airdryers and ironing, dedicated storage for cleaning supplies and linen, and in many cases a mudroom section near the external door.
This size suits larger families, households with pets, or properties where the laundry doubles as the main entry point from the garden or garage.
What the Building Code Actually Requires?
The National Construction Code sets the minimum that any laundry in a residential building must meet, and understanding those requirements helps homeowners know what the floor must include before additional planning begins.
Under Part 10.4 of the NCC Housing Provisions, every residential property must include suitable laundry facilities, with at least one washtub and enough space in the same room to accommodate a washing machine.
A kitchen sink does not satisfy this requirement. The NCC also specifies a minimum ceiling height of 2.1 metres for a laundry, which is the same minimum that applies to bathrooms and other non-habitable rooms.
There is no mandated minimum floor area in the NCC. This is why compact European alcoves, if they include a washtub and machine space, are code-compliant even at a very small footprint.
The Best Layouts for Small Laundry Rooms
Small laundry layouts succeed or fail on how well the available floor area is organised. The most effective layouts for small laundry rooms use every wall from the floor to the ceiling and keep the appliances, bench, and tub as close together as possible to minimise wasted movement space.
In a room under 3 square metres, the single-wall layout performs best: appliances at one end, bench in the middle, storage above the full run. There is no space for opposing runs of cabinetry, and the priority must be vertical rather than horizontal storage.
In a room between 3 and 5 square metres, an L-shaped layout opens up. The appliances sit on one wall, the bench continues around the corner, and the tub anchors the second wall. This gives a much longer effective bench run without requiring a larger room.
The single decision that most improves small laundry function is choosing a front-loading washing machine and stacking the dryer above it. This frees the bench run entirely and recovers the floor space that a top-loading machine and a separate dryer side-by-side would otherwise consume.
European vs Traditional Laundry: How Size Changes the Decision?
The choice between a European alcove and a traditional separate room is fundamentally a question of how much floor space is available and what daily use demands of the room.
European vs traditional laundry configurations serve different households and different homes. The European format works when floor space is tight and the household can manage with minimal bench and no dedicated trough. The traditional format works when the space exists and the household does enough laundry to justify and use the additional function.
The mistake is choosing the European format for a household that genuinely needs the function of a traditional room, or over-building a large traditional laundry for a single-person apartment where a compact alcove would serve the same purpose.
Size should follow the household’s real usage pattern, not a general preference for more space.
Appliances, Benches, and Storage: What Drives the Size You Need?
The size a laundry room needs to be is ultimately determined by what must fit inside it, and the clearest way to plan that is to start with the appliances and work outward.
A standard front-loading washing machine is 600mm wide and 600mm deep. A dryer stacked above it adds no floor footprint. A laundry tub ranges from 300mm to 600mm wide depending on the style. A full-depth bench is 600mm deep and runs for as long as the wall allows.
The Australian Government’s water rating scheme for washing machines shows that compact front-loading models deliver equivalent wash performance to full-sized models at a significantly smaller physical footprint, which matters directly when a smaller laundry room is being planned around appliance dimensions.
Storage drives size as much as appliances do. A household storing bulk detergent, cleaning products, spare linen, seasonal towels, and cleaning equipment needs significantly more overhead cabinet space than one using the laundry for washing only.
Additional practical laundry room ideas worth planning into the footprint include:
- Hanging rail above the bench or on a side wall for air-drying delicates.
- Linen hamper or built-in sorting bins below the bench.
- Recessed shelf or alcove for the iron if a fold-down ironing board is being used.
Laundry Room Design Ideas to Make Any Size Work
Good laundry design ideas treat every centimetre as deliberate rather than incidental. The rooms that feel too small are almost always ones where the storage, bench, and appliances were placed without a clear sequence.
The practical decisions that make any laundry size work better are:
- Fix the door swing before anything else. A door that opens into the room removes usable floor area and blocks appliance access. Bifold, sliding, or pocket doors suit almost every laundry better.
- Take overhead storage to ceiling height. The zone from 1.8 metres up is usable for occasionally accessed items and is wasted in most laundries because the builder left it empty.
- Choose a fold-down ironing board that mounts to the wall. A freestanding ironing board takes as much floor space as a large appliance when open.
- Use the inside of the door. Slim-profile over-door organisers hold cleaning supplies, clothespins, and small items without consuming any floor or bench space.
- Plan the bench height for the primary user. Standard bench height is 900mm, but a household with a shorter primary user benefits from an 850mm bench that reduces the reach and fatigue from regular folding.

Planning Your Laundry Renovation
A laundry planner exercise before any renovation begins means fewer surprises once the build is underway. The two decisions that most affect cost and outcome are the layout type and the joinery specification, and both need to be resolved before trades are engaged or materials are ordered.
Changing the layout after joinery has been manufactured adds cost in every direction. Changing the finish specification once materials have been ordered delays the project. Getting both locked in at the planning stage is the most reliable way to keep a laundry renovation within budget and on schedule.
It is also worth assessing whether the existing plumbing connections can serve the planned layout without relocation. Moving a drain or supply connection adds plumbing cost that is not always visible in an initial quote. A builder who inspects the room before quoting can confirm this before the scope is agreed.

Final Thoughts on Laundry Room Size
How big a laundry room needs to be depends on the household that uses it, not on a number from a style guide.
A compact European alcove is the right answer for a single-person apartment. A 6 square metre separate room is the right answer for a family of five. The laundry renovations that work best are the ones sized for actual use rather than theoretical preference.
Start with the layout type that fits the available floor area, plan the appliances and storage within that layout, and let the function determine the size rather than the other way around.
