Bathroom Renovation Cost

Why one quote says 18,000 and another says 42,000 for the same room — the cost broken down item by item, and what really moves the number.

A bathroom is the most expensive room in the home per square metre, by a wide margin. Every trade meets inside six square metres, and each is on site for only a day or two — so the cost of turning up is spread over a small area. That is why a shower room of six square metres does not cost half of one at twelve.

Ranges by level

As of 2026, for a standard bathroom of 4 to 8 m², materials and labour included:

  • ILS 18,000–25,000 — basic. Standard tile, off-the-shelf fittings, stock screen, no change to services.
  • ILS 25,000–35,000 — the common level. Full pipe replacement, large-format tile, a niche, bespoke vanity, made-to-measure screen.
  • ILS 35,000–60,000 — high specification. Natural stone or very large porcelain, linear drain, underfloor heating, architectural joinery, upper-range brassware.

How it breaks down

  • Strip-out and disposal — 5–8%. More on an upper floor with no lift.
  • Plumbing — 12–18%. Relocating outlets raises this sharply.
  • Electrics and ventilation — 5–8%.
  • Building, screed and preparation — 8–12%.
  • Waterproofing — 5–8%. The cheap item, and the one not to touch. See bathroom waterproofing.
  • Tiling labour — 15–20%.
  • Tiles, material — 10–25%. The most variable item.
  • Sanitary ware and brassware — 10–20%.
  • Shower screen — 5–12%.
  • Joinery and mirror — 5–15%.

What raises the price most

  • Relocating plumbing. Moving a WC one metre is not a one-metre item — it is breaking screed, a new drain line at the right fall, and making good.
  • Large tiles in a small room. Waste of 25% and up, and double the labour on cuts.
  • A bespoke screen. Two to three times an off-the-shelf model, on a four-to-eight-week lead time that has to start early.
  • Linear drain and level access. Adds ILS 3,000 to 8,000, and is sometimes impossible on height. See converting a bath to a shower.
  • Surprises behind the wall. Lead pipework, old damp, poor concrete. In a flat over thirty years old, budget 15% contingency.

What lowers it without hurting the result

  • Do not move the plumbing. The single largest saving available.
  • A common tile size. 60×60 or 60×120 saves material, labour and waste.
  • Concentrate the luxury. One impressive wall with the rest basic reads as more expensive than a whole room done to a middling level.
  • Close the selections in advance. A change mid-works is the costliest item that appears in no quotation.
  • Do not save on waterproofing, ventilation or services. See saving on a renovation.

Comparing two quotes

A 40% gap between quotes is almost never a gap in price — it is a gap in scope. Check that every quote explicitly includes: strip-out and waste disposal, screed and falls, waterproofing and a flood test, tile quantity including waste, whether fittings are supplied or only installed, the screen, and VAT. A quote that comes down to one line is not a quote. See bill of quantities and finishing works cost.

FAQ

Two bathrooms at once — is there a saving?

Yes, usually 10–15% on the second, because setting up, deliveries and trade attendance are shared.

How much contingency?

10% in a relatively new flat, 15–20% in one over thirty years old.

When are payments made?

Against milestones: a deposit of up to 20%, a payment after waterproofing and the flood test, and a final payment after the snagging list is closed.
