The best way to create a laundry room in an existing home is to choose a practical location close to plumbing, confirm enough space for appliances and storage, then plan drainage, ventilation, power, waterproofing, and cabinetry before construction starts. Working with the existing layout where possible can reduce unnecessary changes while still giving you a laundry that feels purpose-built.
Key Takeaways
- Choose a location close to existing plumbing where practical.
- Measure appliances before finalising the layout.
- Plan water, drainage, power, ventilation, and storage together.
- Use vertical space when floor area is limited.
- Complete structural and service planning before ordering cabinetry.
How Do You Create a Laundry Room in an Existing Home?
Creating a laundry room in an existing home means finding a suitable space, running new plumbing and drainage to it, completing waterproofing and substrate preparation, installing cabinetry and appliances, and coordinating the electrical and ventilation connections the room needs to function safely.
Unlike renovating an existing laundry, creating a new one from scratch means starting without the supply lines, waste connections, or structural preparation already in place. Each of those elements must be added in the correct sequence.
The result, when properly planned and built, is a room that handles the household’s laundry demands without pulling it into another room to sort, fold, or store.
Where to Find Space for a New Laundry Room?

You can create a new laundry room under the stairs, in part of a garage, within a hallway or linen cupboard alcove, or by combining it with an existing bathroom.
Under-Stairs Area
The void beneath a staircase is one of the most underused spaces in many Melbourne homes. It often provides exactly the depth and height needed for a compact laundry: enough room for a front-loader, a narrow bench, a tub, and overhead storage. Plumbing is typically not far from the bathroom or kitchen above or beside it.
Converted Garage Laundry
Many Melbourne eastern suburbs homes have a single-car garage or carport that is rarely used for vehicles. Converting part of the garage into a dedicated laundry room creates a properly waterproofed, functional space without touching the internal floor plan. The concrete slab typical of garages is an ideal base for a tiled laundry floor.
Hallway Alcove or Linen Press Conversion
A deep linen cupboard or a wide hallway alcove can be converted into a European-style laundry with stacked appliances, a compact tub, and cabinetry above. This option suits homes where space is genuinely limited. Plumbing access from an adjacent bathroom or kitchen is what makes it practical.
Combined Bathroom and Laundry
In homes with a generously sized bathroom, a section of the room can be reconfigured as a combined bathroom-laundry. This approach avoids the need to extend plumbing to a separate location. It works well in homes where the bathroom is accessed from a hallway rather than from a bedroom, since the laundry use does not conflict with private use of the room.
What Does Creating a New Laundry Room Involve?

Creating a new laundry room involves site assessment and design, structural work, plumbing and electrical rough-ins, waterproofing, tiling, cabinetry installation, and final plumbing connections. Each stage depends on the previous one being completed correctly.
- Site assessment and design — the builder confirms the location, the plumbing routing options, the structural requirements, and the layout that fits the space.
- Structural work — if walls need to be opened, removed, or built, this happens before any plumbing or lining goes in.
- Rough-in plumbing — the licensed plumber runs new supply pipes and a waste drain to the laundry location. This is done while walls and floors are open.
- Rough-in electrical — the electrician positions power points for the washing machine and dryer, exhaust fan wiring, and any lighting while the walls are still accessible.
- Substrate and lining — walls are lined and the floor substrate is prepared for waterproofing.
- Waterproofing — a licensed waterproofer applies membrane to the wet area surfaces, which are then inspected before tiling begins.
- Tiling — floor and any tiled wall areas are completed over the inspected membrane.
- Cabinetry and fit-out — the cabinetmaker delivers and installs the laundry joinery, including bench, cabinetry, and tub.
- Fix-out plumbing — the plumber connects the tub waste, the machine supply lines, and the drainage, then issues the compliance certificate.

Permits and Building Compliance in Victoria
Creating a new laundry room in an existing Melbourne home will almost always require a building permit, particularly where the work involves any structural changes, new plumbing connections, or waterproofing in a new wet area.
A building permit confirms that the proposed work meets Victoria’s building regulations and that a licensed building surveyor has reviewed the plans before work starts. It is not the same as a planning permit, which relates to land use rather than construction standards.
Consumer Affairs Victoria’s guidance on building plans and permits outlines when permits are required, what the process involves, and what the homeowner’s responsibilities are during a building project.
Working without the correct permits exposes the homeowner to compliance issues at the point of sale and may affect building insurance coverage if damage occurs in an area of the home that was modified without approval.
Laundry Layout Ideas for Different Spaces

The layout of a new laundry room is determined by the dimensions of the space and the position of the plumbing connections.
Different laundry layout configurations cover the full range from single-wall through to L-shaped and galley options. For a newly created room, the most common configurations are:
- Single-wall layout: all appliances and cabinetry along one wall, suits narrow alcove and conversion spaces under 1.8 metres wide.
- Galley layout: appliances and bench along opposite walls with a central walkway, works in wider rectangular spaces of 2 metres or more.
- L-shaped layout: cabinetry wraps around two adjacent walls, suits square or near-square rooms that have a door in one corner.
- European alcove: stacked appliances behind bifold or sliding doors, suits the smallest conversions where the laundry hides within an existing opening.
The key constraint in a newly created laundry is that the plumbing waste position is fixed once the rough-in is complete. Agreeing the layout before rough-in saves the cost of relocating connections later.
Laundry Storage Ideas and Design Choices

Good storage turns a functional laundry into a room that manages the household’s laundry from sorting to folding without spilling into other areas.
Laundry renovation ideas for small and functional spaces cover how to make storage work in compact rooms. For a newly created laundry, the design decisions that deliver the most storage for the available space include ceiling-height cabinetry, a pull-out hamper built into the underbench, a fold-away ironing board recessed into the cabinetry, wall-mounted drying rails, and a deep utility tub positioned at the end of the bench run.
Laundry design ideas for material choices prioritise durability: moisture-rated MDF board for cabinetry, hard-wearing vinyl plank or ceramic tile for the floor, and a splashback material that tolerates water and cleaning products.
The bench height is worth specifying rather than accepting a standard: 900mm suits most people for sorting and folding, but taller households benefit from 950mm.
Water and Energy Efficiency in a New Laundry
Building a new laundry is an opportunity to make water-efficient choices from the start, rather than retrofitting around existing appliances.
Sustainability Victoria’s water saving guidance identifies household laundry as one of the significant contributors to home water consumption. Key choices that reduce water use in a new laundry include:
- A front-loading washing machine, which uses significantly less water per cycle than a top loader.
- A cold-fill washing machine connection, allowing wash cycles to run on cold water without drawing from the hot water system.
- A greywater diversion system if the block has a garden that could benefit from laundry water reuse.
- A heat pump dryer, which uses a fraction of the energy of a conventional vented dryer.
Specifying these during the design stage means the plumber positions connections correctly on rough-in day rather than requiring alterations later.

Final Thoughts on Creating a Laundry Room
Creating a new laundry room in an existing Melbourne home delivers one of the most practical improvements a home renovation can offer. A properly planned laundry removes the daily friction of shared bathroom-laundry use, creates dedicated storage, and adds usable, functional space to the home.
The key is sequencing the work correctly: space selection, plumbing rough-in, waterproofing inspection, cabinetry, and fit-out all happen in order, with licensed trades at each regulated stage.
When it is done right, the room works cleanly for decades.
