How to Tile a Kitchen Splashback Yourself (DIY)

A tiled splashback is the highest-impact small tiling job in the house: one weekend, £50–150 in materials, and a kitchen that looks professionally finished. It’s also the perfect first tiling project — small area, straight lines, and any mistakes are at worktop height where only you will ever notice them.

Here’s how to tile a kitchen splashback yourself, from planning the layout to the grouting that makes it look pro. No prior tiling experience needed — just patience and the right technique.

Planning and materials

Measure the area: typically the wall between worktop and wall units, 60cm high, plus any statement areas behind the hob. Buy 10–15% extra tiles for cuts and breakages — and buy them all at once (batch variation is real). For a standard 3m run, that’s roughly 2m² of tiles: £30–80 for decent ceramic, £80–200 for handmade-look or natural stone.

You need: tiles, tile adhesive (ready-mixed tub for splashbacks — £15–20, no mixing), grout (£10–15, choose mould-resistant for kitchens), tile spacers (2–3mm), a notched trowel, tile cutter (a £25 manual score-and-snap cutter handles ceramic; hire or buy a £40 electric wet cutter for porcelain or natural stone), spirit level, and a tile file for smoothing cut edges. Total tool investment if starting from scratch: £60–100 — still cheaper than a tiler’s day rate.

Preparation: the wall must be right

Tiles only look as good as the wall behind them. The wall must be clean, dry, sound and flat — scrape off loose paint, fill holes, and sand glossy paint to give the adhesive a key. On plasterboard, seal with a diluted PVA or tile primer; on fresh plaster, wait 4 weeks for it to dry fully before tiling (tiling damp plaster traps moisture).

Find your starting point before spreading a drop of adhesive. The pro method: find the centre of the area and dry-lay a row to see where the cuts fall. You want cut tiles at the edges (not a sliver on one side and a full tile on the other) — adjust the centre line so the end cuts are balanced and no cut is narrower than half a tile. Mark a level horizontal line for the first row: worktops aren’t always level, and following a wonky worktop makes the whole splashback wonky.

Dry-lay first; balance the cuts so no edge sliver is under half a tile.
Start from a level line, not from the worktop (worktops lie).

How to tile a kitchen splashback yourself: the technique

Spread adhesive with the notched trowel in small sections (about 30 minutes’ worth — it skins over), holding the trowel at 45° to create even ridges. Press each tile in with a slight twist — you’ll feel it bed into the adhesive. Use spacers at every corner, check level every few tiles, and wipe adhesive off tile faces immediately with a damp sponge (dried adhesive in grout lines is miserable to remove later).

Work from the centre outwards and bottom upwards. For the row behind the hob, consider full tiles with no cuts if the measurements work — it’s the focal point. Take your time: rushing causes lippage (tile edges not flush), which catches light and looks amateur. A splashback is small enough that slow and careful costs you an hour, not a day.

Wipe adhesive off faces immediately — dried adhesive ruins grout lines.

Cutting tiles and working around sockets

Straight cuts: score firmly once with the manual cutter (one confident score, not multiple scratches), then snap — practice on a spare tile first. Sockets are the fiddly bit: turn the power OFF at the consumer unit, unscrew the socket faceplate, tile up to the box (cutting tiles to fit around it with the wet cutter or tile nippers for curves), then refit the faceplate over the tiles with longer screws — the faceplate sits proud of the tiles, giving a perfect finish.

For pipes and odd shapes, a £10 pair of tile nippers nibbles curves (slowly — nibble, don’t bite), and a tile file smooths every cut edge. Cut edges go where they’re hidden: under units, behind the hob, at the ends. The visible cuts should be your cleanest — file them smooth and they’ll disappear under grout.

Grouting and finishing

Wait 24 hours for the adhesive to cure, then grout. Mix (or scoop, if ready-mixed) and work the grout into the joints with a grout float held at 45°, pressing firmly — the joints must be fully filled, not just surface-covered. Work in sections, then clean: first pass with a damp (not wet) sponge in circular motions, rinsing often; second pass after 30 minutes to remove the haze. Too much water weakens grout and causes patchy colour — wring the sponge well.

After 24 hours, apply grout sealer (£10–15) — kitchens need it; unsealed grout absorbs grease and stains within months. Run a bead of silicone (not grout) where the tiles meet the worktop — this joint moves, and grout cracks there. Smooth the silicone with a wet finger or tooling stick for the professional finish. Stand back, admire, and try not to tell every visitor that you did it yourself. (You’ll tell them.) If the kitchen needs more than a splashback, our guide to kitchen fitting costs and kitchen paint cover the bigger picture.

Tiling a splashback is the perfect first tiling project: small, forgiving, and transformative. Plan the layout, prep the wall, work slowly from a level line, cut carefully around the sockets, and finish with sealed grout and a silicone edge. One weekend, under £150, and a kitchen that looks like you hired someone. You’ll be looking for the next wall to tile within a month. Which?’s tiling guides cover tools and materials in more depth.
