Question 1

How many tiles do I need for a room?

Accepted Answer

Divide your room area by the area of a single tile (including the grout joint). For example, a 12 m² room with 60×60cm tiles needs about 33 tiles before adding waste allowance.

Question 2

How much extra tile should I buy for waste?

Accepted Answer

Add 10% extra for straight-laid tiles, and 15% for diagonal, herringbone, or patterned layouts to account for cuts and breakage.

Question 3

What size grout joint should I use?

Accepted Answer

Most floor tiles use a 2–5mm grout joint. Larger format tiles (60cm+) typically use 3mm, while smaller mosaic tiles may need wider joints up to 6mm.

Question 4

How many tiles come in a box?

Accepted Answer

Box quantities vary by manufacturer and tile size, but 10 tiles per box is common for medium-format floor tiles. Always check the specific product packaging.
