How Much Does a Bathroom Renovation Cost in Sri Lanka in 2026?
A full bathroom renovation costs Rs 180,000-450,000 per bathroom, covering tiling, sanitaryware, plumbing and waterproofing for a standard-sized bathroom where the layout stays the same. A small refresh of a toilet room runs Rs 90,000-180,000, and a full renovation with a moved layout, imported fittings and large-format porcelain climbs to Rs 500,000-1,000,000 or more.
Those three numbers cover most budgets. The rest of this guide breaks the renovation into its four real cost centres — sanitaryware, tiling, plumbing and waterproofing — and walks through small, medium and full worked budgets so you can see which choices move the number.
This is a composite guide: it pulls together three trades that each have their own detailed pricing elsewhere on Snapwerks — the bathroom fitter, the plumber, and the tiler. The figures below match those pages exactly, so a quote that cites this guide should match a quote that cites any of the three trade pages.
Here is the full 2026 picture for Colombo and the suburbs:
| Cost centre | 2026 rate |
|---|---|
| Bathroom fitter, per day | Rs 4,500 – 7,500 |
| Plumber, call-out and first hour | Rs 2,500 – 4,000 |
| Tiler (tile bass), per day | Rs 4,000 – 6,500 |
| Sanitaryware supply, economy set (commode + basin + shower mixer) | Rs 35,000 – 70,000 |
| Sanitaryware supply, mid-range branded set | Rs 70,000 – 150,000 |
| Sanitaryware supply, imported or designer set | Rs 150,000 – 350,000+ |
| Install a commode, basin and shower set (labour only) | Rs 18,000 – 55,000 |
| Tile a standard bathroom, floor and walls | Rs 55,000 – 160,000 |
| Repipe a bathroom in PPR or PVC, layout unchanged | Rs 35,000 – 90,000 |
| Repipe with a moved commode or shower position | Rs 90,000 – 180,000 |
| Waterproofing a wet area (per sq ft) | Rs 180 – 450 |
| Fit a shower enclosure or glass partition | Rs 45,000 – 160,000 |
| Full bathroom renovation, standard, layout unchanged | Rs 180,000 – 450,000 |
Outstation districts run 10-20% below Colombo on labour. Expect the top of every band during the Avurudu rush in March and April, and again as the south-west monsoon opens in May, when demand for indoor renovation work climbs and every fitter's diary fills up.
What Actually Makes Up a Bathroom Renovation Budget?
Four cost centres, and homeowners consistently underweight one of them.
Sanitaryware — the commode, basin and shower set — is the item most people research before calling anyone, because it is the part you shop for by brand. It splits into three tiers: a local economy set costs Rs 35,000-70,000; a mid-range branded set — better glaze, soft-close seat, a proper mixer — costs Rs 70,000-150,000, where most standard renovations land; and imported or designer fittings, including wall-hung commodes with concealed cisterns and rain shower panels, run Rs 150,000-350,000 or more. Installing that set is separate labour, Rs 18,000-55,000, higher for wall-hung or concealed-cistern fittings that take longer to fit and need a false wall built and waterproofed around the cistern.
Tiling is usually the single biggest line. Tiling a standard bathroom, floor and walls, costs Rs 55,000-160,000 including tiles, adhesive and grout — the same figure published on the tiling cost guide, which covers ceramic, porcelain and granite material and labour bands in far more depth than this guide needs to repeat.
Plumbing — repiping the bathroom in PPR or PVC — costs Rs 35,000-90,000 if the layout stays where it is, and Rs 90,000-180,000 if the commode or shower moves to a new position, because that means breaking floor for a new soil pipe run rather than reusing the existing one.
Waterproofing is the smallest line by rupee value and the most important by consequence: Rs 180-450 per square foot, typically Rs 15,000-40,000 on a standard bathroom. It is also the line contractors are most tempted to skip or rush, because skipping it doesn't show up in the finished tile — only as a damp patch on the ceiling of the room below, usually within two or three monsoons of a badly waterproofed job. Insist on two things regardless of budget: a membrane applied before tiling starts, up the walls to at least shower height and across the full floor, and a flood test — the floor dammed and filled with water for 24-48 hours — to confirm it holds before it gets covered and becomes invisible.
| Cost centre | Share of a standard renovation budget |
|---|---|
| Tiling | 25-35% |
| Sanitaryware (supply + fit) | 25-35% |
| Plumbing | 15-25% |
| Waterproofing | 5-10% |
Worked Example: Small, Medium and Full Bathroom Renovation Budgets
These three tiers cover most renovation jobs quoted in Colombo and the suburbs in 2026.
| Tier | What's included | 2026 budget |
|---|---|---|
| Small — toilet room or powder room refresh | Retile ~20 sq ft floor + ~90 sq ft wall, economy sanitaryware, no layout change, spot waterproofing repair | Rs 90,000 – 180,000 |
| Medium — standard bathroom renovation | Full retile ~40 sq ft floor + ~150-200 sq ft wall, mid-range sanitaryware, full waterproofing membrane, layout unchanged | Rs 180,000 – 450,000 |
| Full / premium — larger bathroom or ensuite | Moved commode/shower position, imported sanitaryware, large-format porcelain, glass shower enclosure, full repipe and rewaterproof | Rs 500,000 – 1,000,000+ |
The medium tier is the one most homeowners actually mean when they ask "how much to renovate my bathroom" — a like-for-like refresh where everything gets replaced but nothing moves. What pushes a job from the medium tier into full/premium territory is almost always one of these three choices, and any one of them alone can add Rs 100,000 or more:
| Choice | Effect on the bill |
|---|---|
| Moving the commode or shower to a new position | +Rs 55,000 – 90,000 (new soil pipe run, floor breaking) |
| Imported sanitaryware instead of mid-range branded | +Rs 80,000 – 200,000 |
| Large-format or imported porcelain instead of ceramic/vitrified | +Rs 40,000 – 90,000 (see the tiling cost guide for the full material breakdown) |
| Glass shower enclosure instead of a curtain or half-wall | +Rs 45,000 – 160,000 |
A full renovation that combines a moved layout with imported fittings on a larger-than-standard bathroom is where quotes climb past Rs 1,000,000 — real, but the exception rather than the norm for a typical Sri Lankan home.
Keep 10% of any budget as contingency. Older Sri Lankan bathrooms frequently hide corroded galvanised pipe, damp-damaged plaster, or an out-of-level floor that only shows up once the old tiles and fittings come out.
How Do You Get a Fair Bathroom Renovation Quote?
Because a renovation touches three trades, get one written scope that names all four cost centres before work starts. Ask directly:
- Does the quote cover sanitaryware supply, or only installation? At which tier — economy, mid-range or imported?
- Is the layout staying exactly where it is, or is anything moving?
- Is a waterproofing membrane and a flood test included, and can you see the flood test before tiling starts?
- What tile size and grade is assumed, and does the price include removing old tiles first?
- Is there a warranty on the waterproofing and on hollow or lifting tiles?
Compare at least two quotes on the same written scope. A gap of 30-40% between two bids on a "same" renovation is almost always a difference in sanitaryware tier or a layout change buried in one quote and not the other — not a difference in skill.
