Bathroom Floor Plans Australia

Bathroom plans are an extremely important aspect of bathroom design, as they lay the foundation for your entire interior aesthetic. A smart layout planner will imagine the space in its entirety before moving on to design, to ensure that the flow of the space is suitable for future appliances and furniture.

The first thing to consider when starting a bathroom layout plan is the size of the proposed bathroom. Size is extremely important as it will determine the number and type of fixtures that will fit inside the room. Pay attention to the measurements of everything from showers to sinks and cabinets to toilet dimensions. The standard bathroom size in Australia is 3m x 2m and is suitable for toilet, shower, vanity unit and cabinets.

There are a few avenues you can take for bathroom design ideas and advice. A variety of different design my bathroom layout apps and planners are available that cover several aspects of bathroom design. From interactive tile designs to full home design apps, the customization is endless.

However, it’s best not to rely entirely on apps and your own view of the bathroom. A qualified interior designer or architect will guide you through the design process and provide practical, professional advice that can prevent long-term problems. For general ideas and inspiration, here’s a breakdown of the most common bathroom layouts in modern Australian homes.

Bathroom plans: 11 layouts ideas and designs

11. Simplicity

It is one of the most common bathroom layouts in Australia. The shower is sectioned off, the toilet design is tucked into the corner facing the door, and the sink/vanity cabinet takes its place in the middle. This bathroom layout is classic, functional and easy to navigate. It emphasizes negative space as much as possible to make the room feel less cluttered.

10. Small narrow bathroom

Narrow bathrooms are hard to style. They usually end up being a variation of this, with the sink next to the door and the shower taking up the entire corner of the room. This ensures maximum space efficiency as the sink requires the least space to maneuver. The downside is that the door will need to be fully closed to comfortably use the sink, which could make cleaning your teeth before bedtime somewhat boring.

9. Long and narrow laundry room

A laundry room next to the bathroom is a great way to save space and keep all your fixtures in one place. It keeps your laundry out of the way, giving you more room in common living areas. A downside to this layout is that you’ll have to go through the bathroom to access the laundry room, which can be a challenge for privacy if you live in a multi-person home.

8. Small bathroom

A bathroom is a private bathroom attached to a bedroom (usually the master bedroom). En-suite bathrooms are becoming increasingly popular in Australia and are particularly common in apartments.

A small bathroom like the one above is known as a “half bath” because it contains the bare minimum of a bathroom: a toilet and a sink. Every inch of space is essential in the design of a small bathroom like this, which makes layout all the more important. For more creative layouts and design ideas, see here.

6. Rectangular bathroom

Rectangular bathrooms offer an intelligent use of space that stimulates the natural flow of space. A rectangular bathroom can have fixtures on both sides, such as a toilet opposite the sink (rather than crammed beside it). This creates a visual path through the room that makes it look more open.

The master bedroom is the most luxurious bathroom in the house. It’s usually quite large, which means you have more freedom in your layout and design choices. Master bathrooms should take advantage of space by using freestanding tubs and extravagant cabinetry.

Walk-in wardrobes are the pinnacle of luxury in modern living. Attaching a walk-in closet to your bathroom gives you a wealth of storage and prep opportunities. The built-in cabinet can store extra bathroom supplies such as emergency shampoo, conditioner, soaps, toilet paper, towels and cleaning supplies. It also makes getting dressed after the shower a breeze!

Three-way bathrooms are the way of the future. As the world continues to shift towards shared homes and apartment living, the focus on privacy becomes critical. A three-way bathroom creates three separate, easily accessible areas for the shower, toilet, and vanity. This means that three people could simultaneously shower, brush their teeth and use the toilet without having to share the space.

1. With walk-in shower
