Are large format tiles more expensive to install?

Yes, typically. Large format tiles require more careful handling, specialised adhesives, and often two installers due to their weight. They may also require additional substrate preparation to ensure the floor is flat enough. All of these factors can increase installation costs.

Can I use large format tiles on walls?

Yes, but there are limitations. Very large format tiles (600×1200mm and above) can be difficult to install on walls due to their weight. Some builders may not offer them for wall applications. Medium large format tiles (600×600mm) are more commonly used on walls, particularly for feature walls and floor-to-ceiling tiling.

Do large format tiles have fewer grout lines?

Yes — that's one of their main advantages. A 600×600mm tile has approximately one-quarter the number of grout lines per square metre compared to a 300×300mm tile. This creates a cleaner look and reduces grout maintenance.

Key Takeaways

Large format tiles (600×600mm or 600×1200mm) create a modern, seamless look with fewer grout lines
They cost more in both materials and installation than standard format tiles
Large format tiles require a flatter substrate to prevent lipping (uneven edges)
They're best suited to large, open floor areas — less suitable for small or irregular spaces
The reduced grout lines mean less cleaning and a more continuous visual flow

Large format tiles have become increasingly popular in Australian home building, prized for their modern, seamless appearance and reduced grout lines. But they come with trade-offs in cost, installation complexity and suitability. Understanding these differences helps you decide whether the upgrade is worth it for your home.

What Are Large Format Tiles?

Standard format tiles are typically 300×300mm or 300×600mm. Large format tiles are 600×600mm or larger, with some tiles now available in 600×1200mm, 750×1500mm and even 900×1800mm. The larger the tile, the fewer grout lines visible, creating a more continuous and modern surface.

Advantages of Large Format Tiles

Fewer grout lines — creates a cleaner, more seamless look
Modern aesthetic — large format tiles are a feature in many contemporary display homes
Less grout maintenance — fewer grout lines means less cleaning and less grout discolouration over time
Can make spaces feel larger — the continuous surface can visually expand a room
Popular for indoor-to-outdoor flow — large format tiles transition well from interior to alfresco

Disadvantages and Considerations

Higher cost — both materials and installation are typically more expensive
Substrate flatness — large format tiles require a flatter floor to prevent lipping (where one tile edge sits higher than the next)
More waste — cutting large tiles to fit irregular spaces produces more waste
Slip risk — large format gloss tiles can be slippery on floors; ensure appropriate slip rating
Weight — large format tiles are heavier and may require two installers, increasing labour cost
Less suitable for small spaces — in small bathrooms or laundries, large tiles can look awkward when cut down

Example Cost Comparison

Tile Format	Example Upgrade Cost
Standard 300×600mm floor tile	Standard allowance
Large format 600×600mm	$50–$100+ per m²
Large format 600×1200mm	$70–$120+ per m²
Additional installation charge	May apply for large format

Real-world examples only. Costs vary by builder, tile specification and installation complexity.

Watch Out

If you choose large format floor tiles, ask your builder about substrate preparation. Large tiles require a flatter floor than standard tiles. If the slab isn't flat enough, tiles can lip (edges sit at different heights), which is both a visual issue and a potential trip hazard.

Where Large Format Tiles Work Best

Large format tiles are ideal for open-plan living areas, kitchens, dining rooms and entryways — large, open spaces where the seamless look can be appreciated. They're also excellent for indoor-to-outdoor transitions where the same tile continues from the living room to the alfresco. In small bathrooms, ensuites or laundries, standard format tiles may be more appropriate.

Questions to Ask Your Builder

What large format tile sizes does the builder offer, and what's the per-m² upgrade cost?
Does the builder charge an additional installation fee for large format tiles?
Is the slab flat enough for large format tiles, or does it need extra preparation?
Can large format tiles be used on walls, or only floors?

Common Mistakes to Avoid

Choosing large format tiles without confirming the slab is flat enough — causes lipping
Using large format tiles in small bathrooms where they look awkward when cut down
Forgetting that large format tiles are heavier and may need two installers — higher labour cost
Assuming large format means fewer installation costs — it often means more substrate preparation

Builder Tips

Large format tiles are ideal for open-plan living areas and indoor-to-outdoor flow
Ask about substrate preparation — large tiles need a flatter floor to prevent lipping
Use medium format (300×600mm) in small bathrooms — large tiles look awkward when cut
Large format tiles reduce grout lines — less cleaning and a more modern, seamless look
