How many rooms is the builder actually tiling? (You could compromise and have 400mm tiling in the laundry, would save you money and probably not such an important room to worry about upsizing to 450mm.) So the “included” is all main floor tiles excluding theatre, bedrooms and wardrobes. It’s a 400 ...

Has anyone had any issues on tiling. I have a pretty inclusive package but because I went a 450 tile instead of a 400 standard I am getting hit with an 8k extra I am tempted to pull all main floor tiling out and sort after handover. Has anyone done this?
