Understanding the Basics: General Rules for a Great Bathroom Floor Plan
To start, it’s crucial to understand what it is that makes a great bathroom floor plan - great. The ideal layout should prioritise both accessibility and comfort, while also creating a visually appealing space.
Start by assessing the size and shape of your bathroom, the location of existing plumbing, and how you use the space daily.
A few general rules for a bathroom layout include:
Keep the main fixtures like the sink, toilet, and shower easily accessible and leave enough space between them for comfortable movement.
Ensure a clear pathway from the bathroom entrance to the main fixtures, and try to separate wet zones (shower and bathtub) from the dry areas (toilet and vanity).
Good lighting, ventilation, and storage are also essential to the overall functionality and ambience of the space.
Understanding these bathroom floor plan basics will provide a good foundation for your design.

Bathroom Vanity Placement: Maximise Functionality and Style
Think of your bathroom vanity as the anchor for the entire space — it’s where you start and end your day, so its placement is critical.
Position your bathroom vanity so it’s not in the direct path of the door. Placing the vanity in line with or directly across from the bathroom door can create a cluttered look and make the space feel cramped. Instead, tuck the vanity to the side or a good distance from the doorway to keep the main entrance clear and make the room feel more spacious.
By keeping the vanity slightly out of the direct line of sight, you’re also create a more private, intimate zone for daily routines. This placement not only enhances the flow of the room but also allows you to use the rest of the bathroom space more efficiently — perfect for fitting in extra storage, a larger shower, or a soaking tub!
Z+S Tip • Utilise wall-mounted options to free up floor space in smaller bathrooms or double vanities in larger spaces to double the functionality + up the luxe factor.

Shower Positioning: Enhancing Your Routine
The shower is one of the most frequently used features in any bathroom, so getting its placement right can make a world of difference to your daily (and nightly) routine.
When thinking about where to place your shower, there are two key factors to keep in mind: accessibility and privacy. For busy bathrooms with multiple users, placing the entrance to the shower where it won’t impact another user’s ability to use the vanity or toilet is important. Frosted or fluted glass screens are perfect for providing extra privacy too.
For small or narrow bathrooms, a corner shower can save space and also open up the room, while in larger bathrooms, walk-in showers or frameless glass doors can create a luxurious feel and enhance the visual flow of the space.
Z+S Tip • Use niches or recessed shelves to provide storage without encroaching on bathroom space.

Optimising Bathtub Placement: Finding the Perfect Spot for Relaxation
Imagine soaking in your bath tub while natural light streams in, or gazing out at a beautiful view — this instantly creates a sense of ambience. If a window isn't an option, position the bath in a quiet corner or an area that feels private and tucked away, giving you a sense of peace and seclusion.
When deciding on bathtub placement, think carefully about the size and style of the tub in relation to your overall bathroom layout.
A freestanding bath can be a stunning focal point in a larger bathroom, acting as a centrepiece that draws the eye. In more compact bathrooms, a built-in bathtub is a smart choice because it conserves space while still offering a nice bathing experience.
Make sure that wherever you place your bath, there’s ample room to move around it comfortably, and it doesn't block access to other fixtures.
This not only ensures safety but also keeps the bathroom looking and feeling nice and spacious.

Toilet Placement Tips: Privacy, Convenience, and Comfort in Your Bathroom Floor Plan
Placing the toilet in the correct position is essential to nail your really functional bathroom layout.
Ideally, you want to position the toilet in a spot that offers privacy without feeling cramped. Great options include locating the toilet behind a half-wall, in a corner, behind the door, or if viable and space allows, in a separate room within the bathroom. The toilet should never be located so it’s not the first thing you see when you enter the bathroom, and ideally off to the side and between other features like the bathroom vanity and shower or the vanity and bath.
These options provide privacy and keep the toilet out of direct sight, contributing to a cleaner, more spacious feel in the rest of the bathroom.
Z+S Tip • For the best bathroom floor plan for toilets, allow at least 75 cm of space in front of the toilet and at least 90 cm total width including the toilet itself.

Towel Storage and Racks: Store Bathroom Essentials Without Compromising Design
Towel storage might seem like a small detail, but take it from us, it plays a huge factor in how functional and organised your bathroom is.
Your towel racks or towel rails should be positioned close to where you need them most — right next to the shower or bathtub. This placement ensures there’s fresh towels always within arm’s reach, adding convenience to your daily routine.
For a modern and space-saving solution, vertical storage like heated towel rails dry towels fast while having the capacity to store more towels than single rails. These options keep your towels tidy and also add a designer touch in keeping with your other finishes.
To further optimise your towel storage, especially for guests, look at including recessed shelves, wall-mounted cabinets, or open shelving units. These are perfect for storing extra towels and other essentials neatly organised, while maintaining a clean, minimalist look.
Remember, accessible storage is key to your functional bathroom design — and will enhance the flow of the space and ensure that everything you need is always easy to find and reach.

Creating Flow: How to Ensure Easy Movement in Your Bathroom Layout
The ideal bathroom layout should allow you to move effortlessly from one area to another. To achieve this, think about how your family or guests will navigate the space and arrange your fixtures accordingly.
Avoid placing large items like the vanity or bathtub directly in the path from the door to the other main features, like the shower or toilet. Instead, aim for a clear, logical route that feels intuitive and natural.
Always leave enough clearance — this means leaving enough room around toilets, baths and vanities for comfortable use and easy cleaning. We cover all clearance planning measurements in the Z+S Bathroom Design + Layout Planner.
In smaller bathrooms, consider using compact vanities, showers and baths, as well as sliding doors to save space and enhance flow.
Remember, the goal is to create a space where everything has its place, and nothing feels crowded or obstructive.

Designing for Different Bathroom Shapes: Small, Narrow, and Large Spaces
Bathrooms come in all shapes and sizes, and each requires a unique design approach to make the most of the available space.
For a small bathroom floor plan, prioritise fixtures that are space-efficient, like wall-mounted toilets, and compact vanities that save space without sacrificing style or function.
In a narrow bathroom design, consider placing all fixtures along one wall to create a more open feel and to keep pathways clear.
If you’re working with a large bathroom layout, you have the freedom to be more creative. Maximise the space by incorporating features like a double vanity for extra storage and convenience, a walk-in shower for luxury, or a freestanding bathtub as a stunning focal point.
Always make sure all elements are well-proportioned and placed thoughtfully so the room feels balanced and connected, rather than empty or disjointed.
