Cost to Tile a Bathroom: What Changes the Price

Area is only the starting point

Tiling is often talked about per square metre, but that figure hides a lot. Cuts around windows, boxing, niches and pipes take time without adding much area. A room with lots of edges costs more to tile than a plain box of the same size.

Tile size and type

The tile itself changes the labour more than most people expect.

• Standard wall tiles are the quickest to fix
• Large format tiles cover area fast but need very flat walls and two people to handle
• Mosaics and small metro tiles are slow because of the number of joints
• Natural stone needs sealing and more careful cutting
• Patterned and encaustic tiles need matching across walls

Wall and floor preparation

Old tiles may need removing, which can pull plaster away with them. Uneven walls may need boarding with tile backer board. Timber floors usually need a backer board or ply overlay to stop movement cracking the grout, and concrete floors may need levelling compound.

Preparation is easy to leave out of a quote and hard to skip on site. Ask exactly what is included.

Waterproofing wet areas

Shower walls and the area around a bath should be tanked before tiling. This adds materials and a curing period, but it protects the structure behind. It is non-negotiable in a wet room, where the whole floor is tanked. Our wet room cost guide covers that in detail.

Set-out and layout

A careful set-out plans where cuts fall so you do not end up with thin slivers at a corner or a doorway. Straight lay is quickest; brick bond, herringbone and chevron add cutting. Feature walls, niches and borders add time. We plan set-out before fixing starts so the finished room looks deliberate.

Trims, grout and silicone

External corners need trims or mitred edges. Mitring looks cleaner but takes longer. Epoxy grout is more stain resistant than standard cement grout and costs more to apply. Every junction with a bath, tray or floor needs a neat silicone seal.

Tiling as part of a full bathroom

If you are replacing the suite too, tiling is usually cheaper as part of a full refit because preparation and plumbing are planned together. If you are only retiling around an existing suite, the existing fittings need protecting or removing and refitting. Our guide to how long tiling takes shows where it sits in the programme.

Floors need extra thought

Floor tiling carries more risk than walls because floors move and take weight. Timber floors should be stiffened and overlaid before tiling, and any underfloor heating mat goes down first and is tested. Thresholds at the door need a neat transition strip so the new floor height does not create a trip. Allow for the toilet and basin pedestal to be lifted and refitted, which is normally part of the job.
