How to Price Tile Replacement: Spot Repair, Full Strip and Re-Lay, Wall vs Floor Margins

Quick Answer: A spot repair (1–4 cracked tiles in an existing run, matching available) prices £140–£320 in 2026. A small wall area re-tile (kitchen splashback, 2–3m²) prices £280–£580. A full bathroom wall re-tile (15–25m² walls) prices £950–£2,400. Floor tiling at £45–£85/m² supplied and laid. The single biggest pricing variable is matching tile availability — when the original tile is discontinued, the customer faces either a feature-tile design solution or a full strip-and-relay of the affected wall, and the cost difference is 4–6×.

Summary

Tiling is one of the broadest pricing categories in the trade because the spread between cheapest and most expensive product is enormous — a basic ceramic wall tile is £8–£15/m² supplied; a high-end natural marble or large-format porcelain is £45–£140/m² supplied. The labour content is also wide because a basic 100×100mm tile installation is fast (30–45 minutes per m²), while a 600×600mm large-format with grout joints under 2mm and a herringbone bond is slow (90–140 minutes per m²).

The market splits into three product categories. Spot repair (£140–£320 typical) is replacing 1–4 cracked tiles in an existing run, only viable when matching tile is available. Re-tile of defined area (£280–£3,800 depending on scope) is removing existing tile from a kitchen splashback, bathroom wall, or floor area and laying new. Full strip and re-lay (£950–£8,500+) is the major bathroom or floor re-tile, often as part of a wider refit.

The single biggest professional risk is tile lipping — adjacent tiles being slightly out of plane with each other, creating a sharp ridge at the joint. Lipping at 1–2mm is acceptable on standard tiles; 0.5mm is the upper limit on large-format (>600mm) tiles. Lipping above 2mm is a defect requiring re-lay. The cause is usually a substrate that's not flat enough — modern self-levelling compounds and tile spacers (clip-and-wedge systems like Raimondi RLS) are essential for large-format work and add £6–£12/m² to the install cost.

Detailed Guidance

Spot repair — when it works and when it doesn't

Spot repair is the cheapest tile fix and works only when:

Procedure:

  1. Score the grout around the damaged tile with a multi-tool or angle grinder
  2. Crack the damaged tile in the centre with a hammer (controlled break, not random shatter)
  3. Lift fragments carefully, avoiding damaging adjacent tiles
  4. Clean substrate — remove old adhesive ridges, dust the area
  5. Apply new adhesive — typical "buttering" of replacement tile back
  6. Seat replacement — push into position, level with adjacent tiles
  7. Allow to set (4–6 hours for rapid-set adhesive)
  8. Re-grout the joints around the new tile (match grout colour as closely as possible)

Total: 60–90 minutes for a single tile, 90–180 minutes for 2–4 tiles. Materials: maybe £10–£30 for adhesive, grout, replacement tile (if from spares).

If the original tile is discontinued, the only options are:

The customer needs to make this choice — frame it for them with both options costed.

Substrate preparation — the make-or-break stage

Tile failures are 80% substrate-driven. The single most important quote-stage check is verifying the substrate is suitable.

Wall tile substrate options:

Floor tile substrate options:

For floor tiling, surface flatness must be SR2 (±5mm under 2m straightedge) for tiles up to 600mm, and SR1 (±3mm) for tiles 600mm and above. Failure to achieve this leads to lipping.

Adhesive selection — get this right or fail

BS EN 12004 classifies tile adhesives by:

Selection rules of thumb:

Wrong adhesive class is the second most common cause of tile failure. A budget C1 adhesive on a UFH floor with porcelain will debond within 6–18 months as thermal cycling stresses the bond.

Grout selection — colour and joint width

Joint width varies by tile size and pattern:

Grout types:

For a customer choosing grout colour: brighter/lighter grout makes the tile pattern more prominent (good for feature tiles); darker grout is more forgiving of staining and ageing (good for kitchens, bathrooms).

Cutting and waste — pricing the offcuts

For straight-line installations on standard tile sizes, allow 8–10% wastage. For pattern-rich installs (herringbone, brick bond, basket weave), allow 12–18%. For natural stone (where colour and pattern variation requires careful selection), allow 12–20%.

Tile cutting tools:

A typical install kit includes both manual snap and wet saw. Hire wet saws are £35–£75/day for single-day jobs.

Lipping — the visual defect that defines quality

Tile lipping is when adjacent tiles are at slightly different heights, creating a small ridge at the joint. Causes:

Acceptable lipping per BS 5385:

Lipping above acceptable is a re-lay scope. For large-format work, a mechanical lipping system (Raimondi RLS, Tuscan Leveling System) is essential — clip-and-wedge devices that hold adjacent tiles flush during adhesive cure. Add £6–£12/m² to the labour cost when using these.

Movement joints — where they're required

BS 5385-3 (floor tiling) requires movement joints:

Joint material:

Skipping movement joints causes tile cracking where the substrate moves, especially with UFH installations and long open-plan floors.

Frequently Asked Questions

How much does it cost to retile a bathroom wall in 2026?

For a single feature wall (4–8m²): £450–£1,100 supplied and fitted. For a full bathroom wall re-tile (15–25m²): £950–£2,400. Includes mid-range porcelain or ceramic, adhesive, grout, edge trim and labour. Substrate condition affects price — sound plaster is direct-tile, but anything wet or unsound needs backerboard at £30–£55/m².

Can I tile over existing tiles?

Yes, in non-wet areas with the right primer. Existing tile must be sound, ungrouted (or grout reinstated), and dust-free. A bond primer (Mapei Eco Prim Grip, BAL Bond It) is applied before tile adhesive. The downsides: tile build-up creates an obvious step at the wall edge or floor threshold, the new install relies on the old install staying bonded, and access for any plumbing behind is removed. For wet areas (showers, splashbacks), strip back to substrate and start fresh.

What's the difference between ceramic and porcelain tile?

Porcelain is fired hotter (>1200°C) from finer clays, giving it lower water absorption (<0.5% by weight, vs ~7% for typical ceramic) and higher density. It's harder, heavier, more frost-resistant, and suitable for floors and outdoor use. Ceramic is cheaper, lighter, and easier to cut, but less durable on floors. For walls, ceramic is fine; for floors, porcelain is the default.

Why are my tiles cracking after a few months?

Three common causes: (1) substrate movement — timber floor flexing, sub-screed cracking, building movement; (2) wrong adhesive — using C1 standard adhesive on a porcelain floor or UFH situation; (3) no movement joints — long floor runs without expansion provision. Diagnosis usually requires lifting one cracked tile and inspecting the substrate beneath. Repair without addressing the cause means recurrence.

How long should grout last?

Cement-based grout in good condition lasts 10–25 years on walls, 8–18 years on floors. Discolouration, hairline cracking, and minor pitting are normal aging. Failed grout (powdery, missing, mouldy) needs raking out and re-grouting (£18–£35/m²). Epoxy grout lasts 25+ years with negligible degradation. Silicon perimeter and movement joints typically need replacing every 3–5 years in wet areas.
