How does the bathroom tile calculator work out floor and wall tiles?

It sizes the floor and walls separately. Floor tiles come from room length times width, divided by the area of one tile in your chosen size. Wall tiles come from the room perimeter times your tiling height, less the door and window openings you deduct. Each part adds your wastage percentage, then rounds up to whole tiles and whole boxes to buy.

What inputs do I need, and what are sensible defaults for an Indian bathroom?

Enter room length and width in feet, pick full-height, dado or floor-only walls, and set the wall or dado height. Add the door and window area to deduct and choose floor and wall tile sizes with their tiles per box. A typical five by seven foot bathroom, nine foot walls, a 300 by 300 floor and a 300 by 600 wall with around ten percent wastage is a reasonable starting point.

How much tile wastage should I allow, and how accurate is the estimate?

Around ten percent suits a plain rectangular bathroom. Allow twelve percent or more for many cuts, niches, skirting or diagonal layouts. The result is indicative for planning and buying, not an exact site figure. Always confirm the true tiles per box, tile dimensions and current stock with your vendor, and keep spare tiles from the same dye-lot, since later batches can differ slightly in shade.
