Bathroom tiles

Bathrooms are usually tiled on both floor and walls, so adhesive use is slightly higher than floor-only. The calculator is pre-set for a typical ~6 m² room — get tiles, adhesive, grout and primer with a 10% cutting reserve.

Enter your own area and openings (door, bathtub) to refine the result.

Tile calculation example and common mistakes

For 24 m² of tiling, a straight layout normally needs a 7–10% cutting allowance; diagonal layouts and rooms with many corners need more. From the net area, the calculator totals tiles, adhesive, grout, primer and selected accessories.

Adhesive consumption is driven mainly by tile size, substrate flatness and trowel notch. In wet rooms, waterproofing, corner tape and pipe collars must be planned separately.

  • Check the coverage stated on each box.
  • Use one production batch for a single room.
  • Large-format tile needs a flat substrate, not an excessively thick adhesive bed.

Frequently asked questions

How much tile waste should I allow?

Usually 7–10% for a straight layout and 12–15% for diagonal or complex layouts. Keep a few spare tiles for future repairs when the product is expensive or hard to source.

Should doors and windows be subtracted?

Subtract large openings. Small areas are often left in because the material is consumed by cuts. Enter the real openings and then choose a sensible waste allowance.

Does the calculator replace a waterproofing design?

No. It estimates quantity; layer count, junction details and product compatibility must follow the selected system data sheet.
