Facteurs de Chute

Pose droite : 10%. Diagonale : 15%. Chevron : 20%. Débutants : ajoutez 5% en plus. 15 m² en diagonale : 15 × 1,15 = 17,25 m². Achetez toujours du même lot — les variations de teinte entre lots sont visibles.

Format

Grands carreaux (60×60) : moins de joints, espace visuellement agrandi. Mais nécessitent un sol parfaitement plat. Pour les salles de bain : 30×60 cm est le meilleur compromis.

⚡ CalcWolf Insight

The most expensive part of a tile job is not the tile — it is the labor. Tile installation runs $7-15 per sq ft for labor alone. The tile itself is $2-8 per sq ft for most residential options. Choosing a $4 tile over a $7 tile saves $360 on a 120 sq ft floor. Choosing to DIY saves $840-1,800. For straightforward floors, DIY tiling is achievable with a $50 tile saw rental and a weekend of patience.
