Questions to ask your installer
Take these to your next conversation with your fitter
- 1Is my floor level enough for large format tiles?
- 2What floor preparation will be needed?
- 3How much extra should I order for waste?
- 4Have you done large format installations before?
- 5What adhesive system will you use?
- 6Can you guarantee a lippage-free finish?
💡 Tip: A good installer will welcome these questions. If they dismiss them, that's a red flag.
💡Myth vs Reality
Common Myth
"Fewer tiles means quicker installation"
The Reality
Large format work takes longer due to handling, levelling, and precision cutting requirements.
Common Myth
"Big tiles make small rooms look bigger"
The Reality
Sometimes, but busy patterns or dark colours can overwhelm. It depends on the specific tile and room.
What to look for
- •Tile thickness - thicker tiles are more stable and less likely to crack
- •Rectified edges for minimal grout lines
- •Through-body porcelain for durability
- •Weight rating - floor structure must support them
Common mistakes
- •Underestimating floor preparation needed
- •Ordering insufficient tiles for waste
- •Assuming any tiler can handle large format work
- •Not budgeting for specialist labour costs
Quality considerations
- •Large tiles show imperfections in the subfloor immediately
- •Quality installation requires levelling compound and premium adhesive
- •Grout choice matters more - fewer lines mean they're more visible
- •Consider the room size - very large tiles can overwhelm small spaces
