Without a doubt, the first critical step in any bathroom renovation is optimising the bathroom layout.

And put simply, this means assessing the existing bathroom floor plan to determine what works and what doesn’t, and then planning the new bathroom layout plan to optimise bathroom space, flow, functionality and aesthetics.

Skip this vital bathroom planning phase, and it could cost you big time — resulting in a bathroom design that’s dysfunctional, and which hasn’t added value to your home that’s equal to how much the bathroom renovation cost.

But don’t sweat… from measuring tips to strategic positioning, we've got the hacks you need for a 10/10 bathroom design layout, so grab your measuring tape and notebook and let's delve into the world of bathroom layout planning!

Plan Plumbing Locations

First things first, if you’re renovating a bathroom with an unconventional bathroom layout, fixing this by remodelling the bathroom should be the #1 priority.

And yes — moving plumbing locations costs money, but a full bathroom renovation cost will set you back in the vicinity of $15,000-$60,000, so spending a fraction of that on moving plumbing to perfect your bathroom layout, is definitely money well spent.

Getting a plumber to assess your bathroom space and give you a ballpark quote for moving plumbing locations, is a wise investment before you venture too far into the design process.

Prioritise Privacy

The best bathroom layout plans have privacy in mind. Position the toilet and shower away from the bathroom entrance or main sightlines to maximise privacy for users and improve your bathroom design layout.

Consider installing a partition wall or frosted glass divider to provide separation of these areas while maintaining an open feel, or for larger bathrooms, you may want to design the toilet so it’s hidden behind a door, in it’s own separate room.

Plan for Wet and Dry Zones

Optimise your bathroom layout plan by designing wet areas, such as the shower or bathtub away from dry zones, such as the vanity and toilet, to prevent water damage and contain water splashing to the one area.

Installation of waterproofing measures by a licenced tiler or waterproofer, such as a waterproof membrane, will protect wet areas to ensure water is contained.

Optimise Bathroom Flow + Spacing

Planning your bathroom layout for good flow is critical and proportions come into play here.

Start by determining whether the bathroom is being designed to accommodate 1 or more users at a time? Then plan your bathroom dimensions accordingly, ensuring the spacing between key bathroom elements like the vanity, toilet and shower will accommodate easy and natural movement.

Account for Door Swing

No matter the size of your bathroom layout dimensions, it’s critical to consider the door swing when planning the layout.

The door swing should not only be optimised to the room design, but also planned around the positioning of bathroom fixtures and cabinetry — to avoid obstruction and ensure ease of use. A swinging door is best for privacy and insulating noise, however for small bathrooms, a space-saving cavity slider door can sometimes be far more practical. That’s because cavity sliding doors tuck into a wall recess when the door is opened, so they don’t encroach on the bathroom footprint or take up any space, unlike a traditional swinging door.

Maximise Ventilation

Become an expert bathroom layout planner by considering the ventilation and air circulation when planning a bathroom remodel.

Exhaust fans should be installed to remove steam and prevent moisture buildup in the bathroom. Consider upgrading to a humidity-sensing fan that automatically adjusts airflow based on moisture levels to maintain optimal indoor air quality at all times.

Customise Storage Solutions

In every room in your home, it’s critical to customise and optimise storage solutions to the layout and user needs… and bathrooms are no exception!

Utilise vertical space with tall cabinets, mirrror cabinets or shelving units to maximise storage without encroaching on floor space, and incorporate niche shelving within the shower or above a bathtub for the optimal storing of toiletries within arm's reach.

When it comes to the bathroom vanity, include both drawers and cupboards, and if your bathroom layout allows, integrate a bin inside to keep rubbish out of sight.

Consider Electrical Outlets

For a practical bathroom layout, strategically plan the location of electrical outlets near vanities and mirrors to accommodate hairdryers, electric shavers, and other grooming tools. If you’re installing a mirror cabinet, include a power point inside to accommodate the storing of small appliances like electric tooth brushes, within easy reach.

Z+S Tip • Conceal electrical outlets inside your vanity drawers or cupboard, so appliances like hairdryers can be stored plugged in ready for use but out of sight.
