How to Choose the Best Bathroom Layout for Your Renovation Project

Back to Blog

The best bathroom layout is the one that suits who uses the room, the space you have and where the plumbing already sits. Measure the room, map the existing plumbing, then choose a three-piece, full bathroom, wet room or ensuite layout. Storage, lighting and finishes follow from that decision, and keeping plumbing in place keeps the job simpler.

Key takeaways

  • The layout is the first and most important decision in any bathroom renovation plan.
  • Match the layout to the people using the room: family, guests or an ensuite for two.
  • Keeping the toilet, shower and drains in place usually simplifies the build.
  • Plan storage, accessibility and ventilation at the layout stage, not after.

Step 1: work out who will use the bathroom

Bathroom typeRecommended layout features
Family bathroomBath plus shower, plenty of storage, durable finishes
Guest bathroomSimple three-piece: toilet, basin and shower
EnsuiteDouble vanity, walk-in shower, premium finishes

A mistake we often see is overdesigning a small space. Function comes first, especially in compact homes and apartments.

Step 2: measure the space properly

  • Measure walls, doors and windows, including ceiling height
  • Mark where the existing drains, water points and fan sit
  • Note which way the door swings and where natural light comes in
  • Allow clearance to move: many designers work to around 700 to 900mm in front of the toilet and vanity

Your builder will confirm clearances and fixture positions against the building code for your specific room.

Step 3: choose the best bathroom layout for your renovation

Step 4: place fixtures smartly

  • Toilet: out of the direct line of sight from the door where possible
  • Shower and bath: on opposite walls in larger rooms, combined in smaller ones
  • Vanity: a double vanity for shared use, wall-hung in small bathrooms
  • Mirror and lighting: where light falls evenly on your face, not behind you

Wall-hung vanities are popular in Queensland homes because they look modern, let air move under the cabinet and make the floor easy to clean.

Step 5: build in storage that works

Storage typeBest use
Recessed shower nicheShampoo and toiletries
Floating shelvesTowels and decor
Drawer vanityDaily essentials
Mirror or wall cabinetHidden storage at eye level

Step 6: plan for accessibility and the future

Planning ahead now avoids a second renovation later. Features worth considering:

  • A step-free walk-in shower
  • A wider doorway
  • Slip-resistant floor tiles
  • Blocking in the walls for grab rails, even if you add them later

These suit families with young children, long-term owners and anyone planning to age in place.

Step 7: get lighting and ventilation right

Queensland humidity makes ventilation critical. Plan it at layout stage, not as an afterthought.

  • Lighting layers: ambient ceiling light, task lighting at the mirror, accent lighting for mood
  • Ventilation: an exhaust fan sized for the room and ducted outside, plus a window if you have one
  • Materials: moisture-resistant cabinetry and finishes throughout
