Plumbing & Sanitary Cost in Singapore: What You'll Actually Pay (2026)

Plumbing splits into two buckets: **fixtures** (installing a toilet, basin, tap or water heater) and **piping** (the pipes behind the wall). Fixtures are cheap and quick. Piping — especially *moving* a sink or toilet — is where the money goes.For a standard HDB reno, basic plumbing is often S$450–S$600 per bathroom and S$350–S$450 for the kitchen. But relocate a sink or toilet and you're looking at a separate S$1,500–S$4,200 scope. Single fixture jobs start as low as S$60.
One rule before anything else: any work connecting to the PUB water main — water heater, new fixture connections, concealed re-piping — must be done by a PUB-Licensed Plumber. Using an unlicensed one voids your HDB warranty and leaves you liable if a leak floods your neighbour.
| Job | Typical cost | Notes |
|---|---|---|
| Toilet bowl set (supply + install) | S$150 – S$500 | Incl. removing the old one |
| Instant water heater (install) | S$180 – S$250 | |
| Storage water heater (install) | S$280 – S$350 | + PUB submission |
| Basic bathroom plumbing package | S$450 – S$600 | Fixtures + exposed piping |
| Relocate sink / toilet (concealed re-pipe) | S$1,500 – S$4,200 | Separate reno scope |
| PUB submission | ~S$300 | Storage heater / main connection |
Indicative 2026 ranges. Final price depends on fixtures, brands, piping (exposed vs concealed) and access.
Fixtures: supply and install
These are the per-item jobs. Branded fittings (TOTO, Kohler, Ariston, 707) cost more, but here's the ballpark:
| Fixture | Cost (supply + install) |
|---|---|
| Toilet bowl set | S$150 – S$500 |
| Wash basin | S$120 – S$300 |
| Basin / mixer tap | S$80 – S$200 |
| Bidet spray | S$30 – S$80 |
| Kitchen sink + tap | S$150 – S$400 |
| Bathroom accessory (holder, rack) | S$10 – S$20 each |
| Instant water heater | S$180 – S$250 |
| Storage water heater | S$280 – S$350 |
Most plumbers also sell a per-bathroom package — heater, basin, toilet bowl, basin tap, bidet spray and a couple of accessories bundled — which usually works out cheaper than buying each install separately. Storage heaters come with a PUB submission (about S$300) because they tie into the main supply.
Piping: the part that costs real money
If your layout stays put, plumbing is cheap. The moment you move something — shift the kitchen sink, relocate the toilet, add a second bathroom point — you're into pipe re-routing, and that's quoted as its own scope: S$1,500–S$4,200.
Two ways to run pipes:
- Exposed piping runs along the wall surface. Cheaper, faster, easy to inspect — common and perfectly fine in service yards and many HDB bathrooms.
- Concealed piping is buried in the wall for a clean look. Costs more because it means hacking, embedding and re-tiling — and if it ever leaks, getting to it is a job.
For most renovations, the honest answer is: keep your wet areas where they are if you can. Moving them is one of the priciest small decisions in a reno.
Repairs, chokes and leak detection
Renovation aside, these are the day-to-day plumbing calls — and the jobs where an upfront price matters most, because they're urgent. From Homees' historical plumber pricing (adjusted to 2026):
| Job | Typical cost | Notes |
|---|---|---|
| Clear toilet bowl choke | S$60 – S$200 | Rodding/auger; severity-dependent |
| Clear floor trap / sink choke | S$50 – S$150 | Most cleared in one visit |
| Repair exposed pipe leak (copper/UPVC) | S$80 – S$200+ | Labour + material |
| Leak detection, concealed pipes | S$120 – S$250+ | Specialist equipment; complex cases cost more |
| Replace flexible hose (sink/cistern) | S$30 – S$60 | Quick fix |
| Re-pipe whole flat (exposed) | S$800 – S$2,500 | Concealed re-piping costs more (hack + re-tile) |
| Transport / troubleshooting call-out | from ~S$80 | Often waived if you proceed with the repair |
Two tips for choke and leak jobs: ask whether the call-out fee is waived if you proceed with the work, and get the plumber to state the price before they start — reputable ones will. A concealed leak that needs detection first should be quoted as two steps (find, then fix), so you're not committed blind.
What your reno package does (and doesn't) cover
This catches a lot of homeowners out. Most HDB renovation packages include basic plumbing — tap replacement, fixture install, floor trap install. They usually exclude:
- concealed pipe re-routing,
- water heater electrical (MCB) upgrades,
- full waterproofing of wet areas,
- PUB submissions for heaters or main connections.
So if your quote looks suspiciously cheap, check whether these are in or out before you sign.
A worked example
Two bathrooms and a kitchen, exposed piping, with instant heaters:
- 2 bathrooms @ ~S$500 each (toilet, basin, tap, bidet, heater) ≈ S$1,000
- Kitchen sink + tap + piping ≈ S$350–S$400
- PUB submission (if storage heater) ≈ S$300
- Total (no relocation): roughly S$1,400–S$1,800
Now relocate the kitchen sink to the other wall, and add S$1,500–S$4,200 for the re-pipe. Same flat, very different bill — and it's the piping, not the fixtures, that did it.
The costs people forget
- PUB submission (~S$300) for storage heaters and main-supply work.
- Concealed re-piping if you want pipes hidden — far more than exposed.
- Water heater electrical — a storage heater may need its own MCB / isolator (that's an electrician cost on top).
- Waterproofing of the wet area — often a separate trade, easy to assume it's "included" when it isn't.
- After-hours call-outs — emergency or weekend work carries a S$150–S$350 surcharge.
- Branded fixtures — TOTO/Kohler/Ariston cost more than house brands.
Rules worth knowing
- PUB-Licensed Plumber required for anything touching the water main — heaters, new fixture connections, concealed re-piping. Non-negotiable for warranty and liability.
- HDB packages include basic plumbing but exclude re-routing and waterproofing (see above).
- Condos usually cost a bit more per job — strata access, lift bookings, and MA/MCST approval for some works.
- Storage heater = PUB submission. Budget the ~S$300 and the lead time.
How to keep the bill sensible
- Don't move your wet areas unless you really need to. Relocation is the single biggest plumbing cost.
- Exposed piping where it won't be seen (service yard, behind cabinets) saves on concealment.
- Bundle fixtures into a package rather than paying per install.
- Confirm what's excluded — re-piping, waterproofing, heater MCB, PUB submission — so it's not a surprise mid-reno.
- Use a PUB-licensed plumber and get an itemised quote. A cheap unlicensed fix that leaks into the unit below costs far more.

FAQ
How much does plumbing cost for an HDB renovation? Basic plumbing is often S$450–S$600 per bathroom and S$350–S$450 for the kitchen. Relocating a sink or toilet is a separate scope at S$1,500–S$4,200. Single fixture jobs can start from S$60.
How much to install a toilet bowl in Singapore? A supply-and-install toilet bowl set runs S$150–S$500, usually including removal and disposal of the old unit. Branded units (TOTO, Kohler) sit at the higher end.
How much does a water heater installation cost? Instant heaters are about S$180–S$250 to install; storage heaters S$280–S$350, plus a PUB submission of around S$300 because they connect to the main supply.
How much to move a kitchen sink or toilet? Relocating wet-area points means re-routing pipes — usually quoted as a separate scope at S$1,500–S$4,200, depending on distance and whether the piping is concealed.
What's the difference between exposed and concealed piping? Exposed piping runs on the wall surface — cheaper, faster, easy to inspect. Concealed piping is buried in the wall for a clean look, but costs more (hacking and re-tiling) and is harder to access if it leaks.
Do I need a licensed plumber in Singapore? Yes, for anything connecting to the PUB water main — water heaters, new fixture connections, concealed re-piping — you need a PUB-Licensed Plumber. Unlicensed work voids your HDB warranty.
Does my renovation package include all the plumbing? Usually only the basics (tap replacement, fixture install, floor trap). Concealed re-routing, waterproofing, heater MCB upgrades and PUB submissions are typically extra — check before signing.
How much does it cost to clear a choke in Singapore? A toilet bowl choke typically runs S$60–S$200 and a floor trap or sink choke S$50–S$150, most cleared in a single visit. Ask for the price before work starts, and whether the call-out fee is waived if you proceed.
How much is leak detection for concealed pipes? Around S$120–S$250+ for labour and specialist equipment, with complex cases costing more. Get it quoted as two steps — detection first, then the repair — so you know each cost.
