Hi construction expert,
That is not really expensive; the tiler has significantly more effort when laying and also more waste. If you also want tile skirting, it gets even more expensive because only the end sides of each strip can be used; the rest of the strip is unusable.
What _exactly_ is the extra effort? There is no additional tile adhesive, after all, it’s the same square meter amount. The large tiles are overall 10% bigger, so that shouldn’t be a real weight problem either. And why more waste? Maybe with diagonal laying, but with straight laying it shouldn’t make much difference. The 24 euro additional cost is already about 2/3 of the tile price, so he must have a lot of waste....
I can somehow understand a bit of extra effort, but 24 euros should easily be 50% of the labor cost!
With the skirting it got even funnier, they seriously want me to buy separate skirting strips instead of cutting them from the tiles. The latter is included in the general contractor price....
Best regards,
Andreas
