How to Measure a Bathroom for Tiles

Create a surface schedule

List each wall and floor separately. Multiply width by height for walls and length by width for floors. Record areas that will not be tiled, but avoid subtracting every small fitting because cuts and breakages consume material.

Note niches, boxing, bath panels, window reveals and concealed areas that are easy to overlook. Decide the finished tile height before ordering.

Allow for the tile pattern

Straight layouts often need less waste than diagonal patterns, herringbone designs or large tiles in a small room. Pattern repeats and book-matched surfaces may require careful selection that increases the order quantity.

The position of the first tile affects the size of cuts at edges. A planned setting-out line can avoid thin, unattractive strips and reduce unnecessary waste.

Specify the whole system

Tiles are only one part of a wet-area installation. Include appropriate backer boards or preparation, waterproofing, primer, adhesive, grout, sealant, trims and movement joints. Products must suit the substrate and exposure.

Grout colour and joint width affect appearance and quantity. Follow the tile and product manufacturers' compatibility guidance.

Know when not to DIY

Leaks often appear after the visible work is finished. Professional waterproofing and installation are sensible for showers, wet rooms, movement-prone floors and uncertain substrates.

Check local electrical safety rules for bathrooms and use qualified trades where required.
