HDB Toilet Bowl Replacement Cost (2026): Labour, Bowl and Extras

A like-for-like replacement usually covers removing the old bowl, fitting and sealing the new one, reconnecting the water and testing for leaks.

The job typically runs in this order:

• The water is shut off at the angle valve and the cistern is drained
• The old bowl is unscrewed from the floor, or broken out if it was bedded in cement
• The floor outlet is cleaned and a new pan collar or seal is fitted
• The new bowl is set, levelled, screwed down and sealed at the base
• The cistern is reconnected with a flexible hose and filled
• Several full and half flushes check for leaks at the outlet, the base and the hose

A like-for-like swap typically takes 1 to 3 hours. It takes longer when the old bowl is cemented in or the new one needs an offset connector.

A standard replacement doesn't include new floor tiles, hacking, moving the bowl to a new position, or fitting a concealed cistern or wall-hung bowl. Ask whether taking away the old bowl is included, because some quotes list disposal separately. On a labour-only job, the bowl, seat and cistern are yours to buy.

The price rises when the new bowl doesn't match the outlet, the old bowl is cemented in, or nearby tiles or valves need work.

• Outlet mismatch. A bowl with a different set-out from your floor outlet needs an offset pan collar. A P-trap bowl, which drains into the wall, needs a connector to reach a floor outlet. Some combinations can't be made to fit.
• Cement-bedded bowls. Older bowls were often bedded in cement, and breaking one out takes longer.
• Damaged tiles. A cement-bedded bowl can chip the tiles around it when it is broken out. Replacing the bathroom floor tiles needs an HDB permit and new waterproofing, which turns a plumbing job into a renovation.
• Worn valves and hoses. A seized angle valve or a perished hose is best replaced while the water is already off. Each is priced separately, and changing the angle valve is PUB Licensed Plumber work.
• Bowl type. One-piece and rimless bowls are heavier to handle, smart bowls need a power point nearby, and wall-hung bowls need a concealed frame and cistern built into the wall.
• Squat to sitting. Converting a squatting pan has its own HDB conditions and is usually priced only after a site visit.

A basic two-piece S-trap toilet bowl costs from about $199 at one Singapore retailer, and one-piece bowls from about $329 on sale.

Those were the cheapest two-piece and one-piece bowls listed on 1 Oct 2026: a two-piece S-trap package at Sim Siang Choon, and a one-piece S-trap bowl on sale at Hoe Kee. Most of Hoe Kee's floor-mounted bowls were listed at $379 to $599. Design, rimless glazing, soft-close seats and brand push prices higher.

Whatever you buy must meet PUB's water-efficiency labelling rules. Since 1 Apr 2019, only fittings rated 2 ticks or higher may be supplied and installed. A 3-tick dual-flush cistern uses 3.5 litres or less on a full flush and 2.5 litres or less on a reduced flush.

For eligible households, a 3-tick bowl also qualifies for Climate Vouchers at participating retailers until 31 Dec 2027.

Measure from the finished wall tile behind the bowl to the centre of the floor outlet, then buy a bowl with that set-out.

There's no single HDB standard. Bowls are sold with set-outs from about 100 mm to 300 mm, 150 mm (6 inches) is the most quoted, and some models adjust across a range. Re-tiling the wall can shorten the distance, so measure your own toilet rather than relying on a neighbour's.

1. Measure from the wall tile behind the bowl, not the skirting or a pipe.
2. With the old bowl fitted, find its model number, often inside the cistern lid or behind the bowl, and look up its set-out.
3. Without a model number, measure to the fixing screws for a rough figure, and choose a bowl with an adjustable set-out.
4. If the old bowl is already off, measure to the centre of the outlet pipe in the floor.
5. For a P-trap bowl, measure from the floor to the centre of the wall outlet instead.
6. Photograph the tape in place, with the space's width, and take the numbers to the shop.

You need a PUB Licensed Plumber, because PUB lists installing, changing or relocating toilet bowls as sanitary plumbing work.

The PUB plumbing works page says all regulated water service and sanitary plumbing work must be carried out by Licensed Plumbers, except a short list of simple works. Since 1 Apr 2018, it has been an offence to engage a plumber not licensed by PUB for regulated water service and sanitary plumbing works. HDB's plumbing guidelines repeat the rule: installing, fixing, replacing or removing a toilet pan must be carried out by a PUB Licensed Plumber.

The simple works a handyman may do include replacing the cistern's flushing mechanism and the flexible hose after the ball valve. The bowl isn't on that list. Neither is the inlet (fill) valve inside the cistern or the angle valve, so have a PUB Licensed Plumber replace either.

Before work starts, search the plumber's name on PUB's licensed plumber search, linked from the same PUB page. HDB's renovation rules say to engage only contractors from its Directory of Renovation Contractors (DRC), including for works that need no HDB approval (HDB: Important information on renovations). Not doing so is an offence. The guide to which plumbing jobs need a PUB-licensed plumber has the full list.
