Every bathroom renovation starts with one big decision: keep the existing bathroom layout or change it. The bathroom layout shapes your renovation budget, your renovation timeline and how well the finished room works every day - keeping the layout saves money and time.
Changing the layout fixes problems that new tiles and tapware cannot. This guide explains when each option makes sense for Melbourne homes, what a layout change involves, and how NOW Bathroom Renovations helps you make the right call.
What Does "Bathroom Layout" Mean?
A bathroom layout is the position of every fixture in the room: the toilet, shower, vanity and bathtub, plus the door and window. Plumbing points fix most of these positions. Each fixture connects to a water supply line and a drainage pipe hidden in the walls or floor, so moving a fixture means moving those pipes. Wall framing, window placement and door swing also shape the bathroom layout. A layout change often involves more than plumbing alone.
When Keeping Your Bathroom Layout Makes Sense
Keeping the existing bathroom layout is the smart choice when the room already works well. A like-for-like layout keeps plumbing in place, reduces demolition and shortens the renovation timeline. Consider keeping your bathroom layout if:
- The room flows well and nothing feels cramped or awkward.
- Your renovation budget is fixed and you want the money spent on visible upgrades.
- Your home sits on a concrete slab, where moving drainage costs more.
- You need the bathroom back in use quickly.
A same-layout renovation still delivers a completely new bathroom. The savings from leaving plumbing untouched can fund premium floor and wall tiles from Beaumont Tiles, quality tapware from Reece, a new bathtub or shower screen from Better Bathware, and vanity cabinetry finished in Polytec or Laminex.
When Changing Your Bathroom Layout Is Worth It
Changing the bathroom layout is worth the extra cost when the current layout causes daily frustration. New finishes cannot fix a door that hits the vanity or a shower too small to turn around in. A layout change often makes sense when:
- The door swing blocks the vanity, toilet or shower.
- The toilet is the first thing you see from the hallway.
- An unused bathtub takes up space that a larger walk-in shower could use.
- Your household has changed, such as a new baby needing a bath or an older family member needing step-free access.
A recent ensuite renovation in Mill Park shows a layout change done well. The home already had a large walk-in shower in the main bathroom but no bathtub, and the owners needed a bath for their young child. The NOW Bathroom Renovations team completely reworked the 2.3m x 2.1m ensuite to fit a combination shower and bathtub, a large wall niche with feature tiling and a mirror cabinet for extra storage. You can see this ensuite and more transformations in our Recently Completed Projects.
How a Layout Change Affects Cost and Compliance
Moving fixtures adds cost because it adds plumbing, demolition and waterproofing work. Understanding these costs early keeps your renovation budget realistic.
Plumbing Relocation
The toilet is the hardest fixture to move. A toilet needs a large drainage pipe with a constant downward fall to the sewer connection, and shower and vanity drains need correct fall too. In homes built on a concrete slab, the slab must be cut and patched to reroute drainage. Homes with a timber subfloor usually give the plumber easier access underneath. Relocating a single fixture in Melbourne can add several thousand dollars to the renovation cost. A layout change also extends the renovation timeline, because new pipework, slab repairs and plumbing inspections must be completed before waterproofing and tiling begin.
Permits and Compliance
A like-for-like bathroom renovation in Victoria generally does not need a building permit. Moving or removing a load-bearing wall is structural work, and structural work requires a building permit. Any plumbing work valued at $750 or more requires a compliance certificate from a licensed plumber under Building and Plumbing Commission rules. Waterproofing for the new shower and floor area must meet Australian Standard AS 3740, whichever layout you choose.

Middle-Ground Options: Small Changes, Big Results
A full layout change is not the only way to improve how a bathroom works. Small adjustments within the existing plumbing footprint often solve the main problems at a lower cost. Popular middle-ground options include replacing a shower-over-bath with a walk-in shower in the same footprint, swapping a hinged door for a cavity sliding door, and installing a wall-hung vanity to open up floor space. A recessed shower niche replaces bulky shelving, and moving the vanity a short distance along the same wall needs only small extensions to the supply and waste pipes. Each of these options improves daily use without the cost of moving the toilet or shower drainage.
