Plumbing Services in Singapore: The Complete 2026 Guide
Residential plumbing in Singapore covers six core job families: choke clearing, leak repair, taps and mixers, toilet repairs, water heater work and pipe replacement. Most common repairs cost S$60–$280 — a toilet choke starts from S$80 and a concealed pipe leak runs S$250–$600. Only "water service work" on the potable supply legally requires a PUB-licensed plumber; everyday repairs like tap washers and choke clearing do not.

What do plumbing services in Singapore cover?
Almost every residential call-out falls into one of six families. Knowing which one you have makes quotes faster and harder to inflate:
- Chokes and blockages — toilet bowl, kitchen sink, basin, floor trap or the shared discharge stack. Recurring chokes usually mean the blockage is deeper than the fixture. See toilet choke service for the full breakdown of clearing methods.
- Leak repair — visible leaks at joints, traps and flexible hoses, and concealed leaks inside walls or floor slabs that show up as stains, damp cabinets or a rising water bill. Diagnosis paths are covered under water leak repair.
- Taps and mixers — washer and cartridge replacement, or swapping the whole tap body when it has corroded. A dripping tap is the cheapest fix on this list; see tap leaking fix.
- Toilet repairs — flush valves, fill valves, cistern reseals and full bowl replacement.
- Water heaters — instant (multipoint or single-point) and storage heater installation or replacement. Pricing depends on heater type; details at water heater installation cost.
- Pipe work — repairing or replacing exposed pipes, re-piping concealed runs after a slab or wall leak, and relocating supply points during renovation.
All six families, plus booking and warranty terms, are gathered on the main plumbing services Singapore hub.
How much does a plumber cost in Singapore in 2026?
These are the price bands FixMove publishes and works to. Labour and basic materials for standard scope are included; premium-brand parts and hidden rectification add to the final quote, which is always confirmed in writing before work starts.
| Job | Typical 2026 price | Notes |
|---|---|---|
| Toilet choke clearing | From S$80 | Bowl-level clear; high-pressure jetting from S$150 for deeper blockages |
| Kitchen sink unclog | S$80–$140 | Includes trap removal if needed |
| Floor trap / stack snaking | S$120–$180 | The right fix when a choke keeps coming back within weeks |
| Tap replacement | S$60–$120 + tap | Labour only; tap cost separate (parts S$30–$120 by brand) |
| Leak repair | From S$80 | Exposed joints, traps, flexible hoses |
| Basin replacement | S$150–$280 | Includes pipe fitting and silicone |
| Water heater installation | S$120–$450 | Instant S$120–$250; storage S$200–$450 (unit cost separate) |
| Concealed pipe leak | S$250–$600 | Detection, partial hacking, re-pipe and patch; tiling excluded |
| Major plumbing rework | From S$1,500 | Multi-point re-pipe or whole-flat plumbing rework |
The full, regularly updated list lives on the plumber cost Singapore price page. The three variables that move a quote most are scope (how many fixtures or rooms), material tier, and site condition (accessibility and hidden damage).
When is a PUB-licensed plumber legally required?
PUB, Singapore's National Water Agency, licenses plumbers for water service work — installing, altering or removing pipes and fittings connected to the potable water supply — and for works on sanitary discharge pipework. This work must comply with the Singapore Standard code of practice for water services (SS 636). General repairs that do not alter the supply or discharge pipework can legally be done by any competent repairer.
| Needs a PUB-licensed plumber | Does not need one |
|---|---|
| Extending or relocating water supply pipes (e.g. moving a sink during renovation) | Replacing tap washers, cartridges or a like-for-like tap |
| Installing or replacing a water heater connected to the supply pipework | Clearing a toilet, sink or floor trap choke |
| Re-piping after a concealed pipe leak | Replacing a flexible hose, bidet spray or shower head |
| Works on sanitary discharge stacks and drainage pipes | Resealing a cistern or replacing a flush/fill valve |
| Any work connecting to or modifying the water service installation | Sealing minor joint leaks on exposed fittings |
One related rule: if a storage heater needs a new heater point, the electrical side is regulated separately — new wiring must be done by an EMA-licensed electrical worker. A responsible company tells you up front which category your job falls into; FixMove states it in the WhatsApp quote before booking.
Emergency vs scheduled plumbing: what changes?
An emergency is anything with uncontrolled water: a burst pipe, a leak you cannot isolate, or a toilet overflowing onto the floor. Everything else — a dripping tap, a slow drain, a heater replacement — is cheaper and better done as a scheduled job.
If water is actively flowing, do this before calling anyone:
- Close the nearest isolation valve (under the basin or beside the cistern), or the main stopcock — in most HDB flats it is inside the service duct near the entrance.
- Switch off the water heater if the leak involves hot water pipes.
- Send a short video on WhatsApp so the plumber arrives with the right parts.
Emergency call-outs start from S$80 and are triaged on WhatsApp first — see emergency plumber Singapore for response times and after-hours coverage. Scheduled jobs get the standard rates above; weekday morning requests usually get a same-day afternoon slot.
How do you vet a plumber in Singapore?
Five checks separate a reliable plumber from a "cheap call-out, expensive surprise" operator:
- PUB licence check — for any water service work, ask for the plumber's name and licence number and verify it against PUB's public register of licensed plumbers on the PUB website.
- Written quote before work starts — a WhatsApp message counts. The quote should name the job, the price band, and what is excluded (e.g. tiling after a concealed-pipe repair).
- Itemised pricing — labour and parts listed separately. "Lump sum, decide on site" is where inflated bills hide.
- Registered business — check the company's UEN on ACRA's BizFile. Flyer operators with no traceable entity leave you nowhere to go if a repair fails.
- Workmanship warranty in writing — 30 days on the repaired part is the reasonable market standard. No warranty usually means no return visit.
HDB vs condo: what is different about the plumbing?
HDB flats
HDB plumbing is built around shared vertical stacks and a per-flat service duct, with three practical consequences. Recurring chokes can originate in the shared stack rather than your own fixture, so a snake through the floor trap often matters more than another bowl-level clear. Ceiling leaks are usually inter-floor seepage from the unit above — HDB treats this as a shared responsibility, and under its Goodwill Repair Assistance scheme repair costs are typically split between the upper and lower flat owners. Renovation-scope work such as relocating a sink or adding a heater point must follow HDB renovation guidelines and use appropriately licensed tradespeople.
Condominiums
In a condo, pipes inside your unit are your responsibility, while risers and common pipework belong to the MCST. Anything touching common property — including some concealed pipe runs — needs management approval first, and most managements restrict noisy work such as hacking to weekday working hours. Many condos also run pressurised systems from roof tanks or pumps, so a leak can discharge faster than in an HDB flat — know where your unit's isolation valve is.
How do you prevent plumbing problems in the first place?
- Never pour cooking oil or grease down the kitchen sink — it solidifies in the pipe and is the most common cause of kitchen chokes.
- Flush only the three Ps — pee, poo and (toilet) paper. Wet wipes, even "flushable" ones, are a leading cause of toilet and stack chokes.
- Lift and rinse floor trap covers monthly; hair and sediment build-up is the cheapest problem to prevent.
- Replace braided flexible hoses (under basins, behind cisterns) every 5–7 years — they fail suddenly and flood fast.
- Watch your water bill — an unexplained jump is the classic sign of a concealed leak. Confirm by closing all taps and checking whether the meter still moves.
- Service storage water heaters periodically and replace units showing rust streaks or weeping relief valves before they fail.
- Fix small drips early. A dripping tap is a S$60–$120 labour job; the corrosion and seepage it causes later is not.

FAQ
Do I need a PUB-licensed plumber for every repair?
No. PUB licensing is legally required only for water service work — installing, altering or removing pipes and fittings connected to the potable water supply, and works on sanitary discharge pipes. Everyday repairs such as tap washers, basin traps and choke clearing do not require a licensed plumber.
How much does a plumber cost in Singapore in 2026?
Typical 2026 prices: toilet choke from S$80, tap replacement S$60-$120 labour, leak repair from S$80, kitchen sink unclog S$80-$140, basin replacement S$150-$280, water heater installation S$120-$450, concealed pipe leak S$250-$600, major plumbing rework from S$1,500.
How do I check if a plumber is PUB-licensed?
PUB publishes a public register of licensed plumbers on its website. Ask the plumber for their full name and licence number, then verify it against the PUB register before any water service work starts.
What counts as a plumbing emergency?
Anything with uncontrolled water flow: a burst pipe, a leak you cannot isolate, or an overflowing toilet. Close the stopcock or isolation valve first to stop the water, then send a short video on WhatsApp so the plumber arrives with the right parts. Emergency call-outs start from S$80.
Who pays for a ceiling leak in an HDB flat?
Inter-floor seepage in HDB flats is treated as a shared responsibility between the upper and lower flat owners. Under HDB's Goodwill Repair Assistance scheme, repair costs are typically split between the two households. Diagnosis usually starts in the upper unit's bathroom floor slab or concealed pipes.
