When designing or renovating a bathroom, understanding the ideal bathroom layouts with dimensions is crucial. This guide will explore various bathroom layouts suitable for Australian homes, complete with dimensions to help you create a functional and stylish space.
Factors to Consider Before Choosing a Bathroom Layout

- Size and shape of the bathroom
- Number of users and their needs
- Budget and desired aesthetic
- Plumbing and electrical considerations
Common Bathroom Layouts in Australia
1. One-Way Layout
The one-way layout is perfect for narrow bathrooms. It features a linear arrangement of fixtures, with the toilet, vanity, and shower or bathtub placed one after the other. This layout maximises space and is ideal for small to medium-sized bathrooms.

| Fixture | Minimum Dimension (W x D) |
|---|---|
| Toilet | 600mm x 400mm |
| Vanity | 750mm x 450mm |
| Shower/Bathtub | 900mm x 900mm (shower); 1700mm x 700mm (bathtub) |
2. Two-Way Layout
The two-way layout is an L-shaped design that works well in square or rectangular bathrooms. It separates the toilet from the vanity and shower or bathtub, providing more privacy and a better flow.
| Fixture | Minimum Dimension (W x D) |
|---|---|
| Toilet | 600mm x 400mm |
| Vanity | 750mm x 450mm |
| Shower/Bathtub | 900mm x 900mm (shower); 1700mm x 700mm (bathtub) |
3. Wet Room Layout
Wet rooms are popular in modern Australian homes, featuring an open, waterproof space with no barriers between fixtures. They are ideal for small bathrooms and those with mobility issues. Ensure the room is well-ventilated and has a low-profile shower drain to prevent water from pooling.
| Fixture | Minimum Dimension (W x D) |
|---|---|
| Toilet | 600mm x 400mm |
| Vanity | 750mm x 450mm |
| Shower | 900mm x 900mm |
4. Central Fixture Layout
The central fixture layout is perfect for large bathrooms, with the vanity or freestanding bathtub placed in the centre, surrounded by other fixtures. This layout creates a luxurious, spa-like feel.

| Fixture | Minimum Dimension (W x D) |
|---|---|
| Vanity/Freestanding Bathtub | 1200mm x 600mm (vanity); 1700mm x 700mm (bathtub) |
| Toilet | 600mm x 400mm |
| Shower | 900mm x 900mm |
Tips for Creating an Efficient Bathroom Layout
When planning your bathroom layout, consider the following tips for a functional and efficient space:
- Place the toilet away from the entrance to ensure privacy
- Position the vanity near the door for easy access to the sink
- Install fixtures with clear walkways between them
- Maximise storage with built-in cabinets, shelves, and wall-mounted units
- Consider using a combination of fixtures, such as a shower-bathtub combo, to save space
By understanding the ideal bathroom layouts with dimensions and considering your specific needs, you can create a functional and stylish bathroom that suits your Australian home. Happy designing!
