Short answer: Sanded grout is used for wider tile joints, high‑traffic floors, and durable, long‑lasting installations.
Why: It contains sand, which gives it strength, reduces shrinkage, and prevents cracking in larger joints.
Sanded grout is the standard choice for floors because it can handle:
Heavy foot traffic
Movement and vibration
Larger grout joints (⅛" to 1½")
Wear and abrasion
Examples:
Kitchen floors
Bathroom floors
Hallways
Commercial spaces (stores, restaurants)
If wall tile joints are ⅛ inch or wider, sanded grout is preferred because it:
Holds shape better
Doesn’t shrink
Stays crack‑resistant
Examples:
Subway tile with wide joints
Decorative stone walls
Shower walls (if joints are wide)
Sanded grout works well with:
Porcelain
Ceramic
Many natural stones (slate, travertine, granite)
Because it fills deep, uneven joints more effectively.
