What Is the Maximum Tile Size for a Shower Floor? Tiling Tips For Sydney Properties
Choosing the right tiles for your shower floor isn’t just about aesthetics—it’s a blend of design, safety, and practicality.
With the growing popularity of sleek, minimalist bathrooms in Sydney, homeowners are increasingly drawn to large-format tiles.
But how big is too big when it comes to your shower floor?
We’ll answer that question in this guide.
Larger tiles can create a modern, seamless look that’s perfect for contemporary bathrooms, but it’s important to know that tile size can impact safety and drainage.
If you’re considering an upgrade or designing a new shower, understanding the right tile size is crucial. The wrong size could affect water flow, grip underfoot, and even how easy the space is to clean.
This article dives into the maximum tile size you should use for a shower floor, breaking down key factors like safety, regulations, and design trends. By the end, you’ll have a clear idea of the ideal tile size for your space, ensuring both function and flair.
Let’s get right into it.
For optimal performance and safety, it’s recommended to use tiles no larger than 150x150mm on a shower floor. This size strikes a good balance between aesthetics, functionality, and safety. |
Choosing the Right Tile Size for Your Shower Floor: Pros and Cons
When it comes to selecting tiles for your shower floor, the choices are vast. From small mosaic tiles to large-format slabs, each option has its own unique benefits and challenges.
Understanding these differences can help you make the right decision for your bathroom design, whether you’re renovating or building from scratch.
Types of Shower Floor Tiles
- Small Tiles (Mosaics): These typically range from 25mm x 25mm to 50mm x 50mm. Mosaics are often used in showers because they offer more grout lines, providing better grip and slip resistance. Plus, they’re flexible enough to fit any shower shape, especially with sloped floors for drainage.
- Medium Tiles (100mm x 100mm to 150mm x 150mm): These tiles offer a good balance between style and function. They’re large enough to minimise grout lines, making cleaning easier, while still providing enough traction to avoid slipping.
- Large Format Tiles (200mm x 200mm and above): Popular for creating a sleek, modern look, large tiles can make a small bathroom feel more spacious. However, they’re more challenging to install on shower floors due to the slope needed for proper drainage.
Advantages of Larger Tiles
- Fewer Grout Lines: With fewer grout lines, large tiles are easier to clean and maintain. Less grout also means a more seamless, minimalist look, which is ideal for modern designs.
- Aesthetic Appeal: Larger tiles can create the illusion of more space, which is perfect for smaller bathrooms. They also provide a more streamlined, luxurious appearance that many homeowners love.
- Durability: With fewer grout lines, there’s less risk of moisture getting into the grout, which can lead to long-term damage. Large tiles tend to be more durable over time.
Challenges of Larger Tiles on Shower Floors
- Drainage Issues: One of the main challenges with large tiles is ensuring proper drainage. Since shower floors need to slope slightly to guide water towards the drain, larger tiles can be difficult to work with in this type of setting.
- Slip Resistance: The larger the tile, the fewer grout lines there are to provide grip. This can make the shower floor slippery, especially when wet, posing a safety hazard.
- Installation: Larger tiles are trickier to install, especially on a shower floor where precise cutting and sloping are required. It may also result in higher labour costs if you’re hiring a professional.
Selecting the right size tile for your shower floor involves balancing aesthetics, functionality, and safety.

So, what’s the sweet spot when it comes to tile size for your shower floor?
While large-format tiles are trending in many parts of Sydney, when it comes to your shower floor, there are practical limitations to keep in mind.
General Recommendation: For optimal performance and safety, it’s recommended to use tiles no larger than 150x150mm on a shower floor. This size strikes a good balance between aesthetics, functionality, and safety.
Why 6×6 Inches or Smaller?
- Safety Considerations: Smaller tiles, like mosaics or 4×4 to 6×6 inch tiles, offer better slip resistance. With more grout lines, these tiles provide additional grip, which is critical in a wet environment like a shower. Larger tiles may become slippery when wet, increasing the risk of accidents.
- Drainage Efficiency: Shower floors require a slope towards the drain to prevent water pooling. Larger tiles are harder to manipulate around this slope. Smaller tiles, on the other hand, can contour to the slant more easily, ensuring water flows directly to the drain without issues.
- Ease of Installation: Larger tiles can present a challenge when trying to achieve the necessary drainage slope, especially if your shower has multiple curves or an uneven surface. Smaller tiles are easier to cut and lay in these scenarios, making the installation process smoother and more efficient.
- Aesthetic Versatility: While large-format tiles might be a no-go for the floor, you can still use them on the walls for that sleek, expansive look. Pairing smaller tiles on the floor with larger ones on the walls can give your bathroom a dynamic, stylish contrast while keeping safety at the forefront.
What About Larger Tiles?
Though it’s not common, some homeowners still opt for larger tiles on their shower floors. If you’re set on this look, there are a few things you can do to minimise the downsides:
- Non-Slip Coating: To counteract the smooth surface of large tiles, you can apply a non-slip coating to increase traction.
- Textured Tiles: Another option is to choose tiles with a natural texture or anti-slip finish, which can provide more grip, even if they’re larger.
- Professional Installation: If you’re keen on using tiles larger than the recommended 6×6 inches, make sure you work with an experienced tiler. They can advise on any potential issues and ensure the tiles are installed correctly to prevent drainage problems.
While the trend of larger tiles is tempting, the practicalities of a shower floor suggest sticking with 6×6 inch tiles or smaller ones.
Conditions to Consider When Choosing Tiles
- Type of Shower: Whether you’re working with a walk-in shower, a standard enclosed shower, or a shower over a bathtub, the type of shower space you have will impact your tile choice. Walk-in showers with minimal barriers often benefit from smaller tiles because they can accommodate a more significant slope towards the drain, which is crucial for such open designs.
- Water Exposure: The level of water exposure in your bathroom may influence your tile choice. For instance, in high-exposure areas, like the shower itself, choosing smaller, slip-resistant tiles is critical. For areas less exposed to water, you have more flexibility with tile size.
- Substrate Considerations: The surface you’re tiling on, whether it’s a concrete slab, a timber base, or a waterproofing membrane, plays a role in determining the type of tiles you should use. Smaller tiles typically adhere better to uneven or sloped surfaces, which are common in shower floors.
