Bathroom Tiling Cost per Square Metre

Tiling labour in our area typically runs £35-£55 per square metre for standard-format ceramic or porcelain tiles up to around 300x600mm, rising to £55-£80 per square metre for large-format tiles over 600x1200mm, which take longer to cut, lift and level. Mosaics, despite being small, also sit at the higher end, typically £50-£75 per square metre, because of the sheer number of pieces and grout lines involved.

These rates cover fixing only, not materials, adhesive, grout or trims, which are priced separately. A fitter quoting a single all-in figure should still be able to break this down if asked.

Materials vary enormously. Basic ceramic wall tiles start around £15-£25 per square metre, mid-range porcelain £30-£60 per square metre, and premium large-format or natural stone-effect porcelain £60-£110 per square metre. On top of the tiles themselves, budget for adhesive, grout, primer and trims, typically adding £8-£15 per square metre regardless of tile choice.

Buying tiles directly from a tile warehouse rather than through the fitter can save 15-25%, though it's worth confirming your fitter is happy to fit customer-supplied tiles and who's responsible if there's a shortfall or defect in the batch.

Large-format tiles look striking with fewer grout lines, but they need a genuinely flat substrate, since even a small dip that a small tile would bridge easily can leave a large tile rocking or lippage-prone. This often means extra substrate levelling before tiling starts, and large tiles typically need two people to lift and place safely, which is reflected in the higher labour rate.

Cutting large-format tiles around fittings, corners and pipework also takes longer and carries a higher risk of breakage, particularly with thin porcelain, which is worth factoring into both the cost and the timeline of the job.

Before any tile goes on the wall or floor, the substrate needs to be sound, flat and, in wet areas, properly waterproofed. On existing plaster or plasterboard walls in reasonable condition, this might just mean a coat of primer, adding little cost. On uneven or damaged walls, levelling compound or new tile backer boards may be needed, typically adding £15-£30 per square metre.

Floors often need a self-levelling compound before tiling, particularly in older properties with uneven screed, which typically costs £10-£20 per square metre plus labour. Skipping this step to save money is one of the most common causes of cracked grout lines and loose tiles later on.

Mosaics are popular for shower floors and feature strips because the many small grout lines give better grip and can follow curves and falls that large tiles can't. The trade-off is labour time, a mosaic floor can take noticeably longer to lay than the same area in standard-format tile, which is reflected in the £50-£75 per square metre labour rate.

Feature walls, using a premium tile on just one wall while tiling the rest of the room in a cheaper option, is a common way to get a striking look without tiling the whole room at the premium rate, and is worth discussing at quote stage if budget is tight.

The only reliable way to get an accurate per square metre figure for your bathroom is to measure the actual wall and floor area to be tiled, including an allowance for waste and cuts, typically 10%, and get a written quote that separates labour, tiles and materials.
