Wash Basin Installation & Replacement in Singapore
Replace a wall-hung, pedestal, countertop, semi-recessed or inset bathroom basin with the fit checked before the visit. FixMove separates one-to-one installation labour from the basin, tap, waste fitting, countertop and any pipe alteration so the quote is comparable.

Quick answer: wash basin replacement cost
A straightforward one-to-one wash basin replacement has an indicative labour guide of S$140–S$220 when the new basin fits the existing mounting and accessible water and waste connections. The exact written quote is based on photos, basin specifications, access and whether existing fittings can be reused.
- Disconnect and remove the old basin from its installed position
- Position and secure the compatible replacement basin
- Reconnect the existing compatible inlet and waste fittings listed in the quote
- Apply sanitary sealant where required
- Fill, drain and check visible joints for leaks
Price boundary: the new basin, tap or mixer, flexible hoses, angle valves, pop-up waste, bottle trap, brackets, off-site disposal, cabinet or countertop work, stone cutting, tiling, waterproofing, pipe relocation and hidden repairs are separate unless written into the quote. When the tailpiece, pop-up waste, trap and wall connection are redone together, the existing full basin/sanitary connection planning band is S$150–S$280 instead of the basin-only labour band. A S$10 fuel surcharge applies per visit; there is no additional standard call-out or inspection fee. An urgent or customer-requested appointment time adds one optional S$30 service fee, subject to availability and confirmation. Read the pricing terms.
Check the basin fit before buying
A basin can look similar online but still fail to match the existing wall brackets, countertop opening, tap arrangement or waste height. These five checks prevent an avoidable second visit.
Overall dimensions
Measure width, front-to-back depth and height. For a vanity or countertop basin, also measure the opening and available cabinet clearance.
Mounting type
Confirm wall-hung, pedestal, countertop/vessel, inset, semi-recessed or undermount. A different mounting type usually changes the scope.
Tap-hole layout
Check zero, one or three tap holes and their spacing. A wall-mounted tap needs the spout reach checked against the new bowl.
Waste and overflow
Match the waste diameter and whether the basin has an overflow. The pop-up waste must be compatible with the basin design.
Outlet position
Photograph the bottle trap or P-trap and where it enters the wall or floor. Misaligned outlets may need new fittings or pipe alteration.
Support and wall condition
Existing brackets, anchors, vanity panels and wall finish must be sound. Loose tiles, damp boards or corroded fixings are separate repair items.
Which basin type are you replacing?
The S$140–S$220 planning range is for compatible one-to-one work. Changing basin type can add fabrication, support, finishing or pipe scope.
| Basin type | What must match | Common extra scope |
|---|---|---|
| Wall-hung basin | Bracket or bolt centres, wall strength, tap holes and waste height | New anchors, brackets, tile making-good or pipe alignment |
| Pedestal basin | Wall fixing, pedestal height, floor position and concealed clearance | Floor or wall finishing, trap access and altered supply routes |
| Countertop / vessel basin | Base footprint, waste opening, tap reach and cabinet clearance | Countertop drilling, tall mixer or wall-tap adjustment |
| Inset / semi-recessed basin | Exact cut-out dimensions, rim coverage and cabinet depth | Countertop or vanity modification and edge sealing |
| Undermount basin | Stone opening, fixing rail or clips, bowl profile and adhesive surface | Stone specialist work, cabinet access and temporary support |
Countertop warning: do not assume a new inset or undermount basin will fit an existing cut-out because the advertised width is similar. Send the manufacturer cut-out drawing before purchase; stone cutting and countertop alteration are separately assessed.

Replacement, repair or a different plumbing page?
One page should own one search intent. Use this page when the basin itself is cracked, damaged, loose, outdated or being changed. Use the matching page below when the basin can stay.
This is blockage intent. See wash basin clog clearing.
The basin may be sound. See bottle trap replacement.
Keep the basin and assess the fitting. See leaking tap repair.
This is cabinet or countertop scope. See bathroom vanity and cabinet work.

Simple replacement versus regulated plumbing work
PUB's official Plumbing Works guidance lists installation, replacement or removal of washbasins or sinks and their immediate below-basin traps as simple plumbing works. A standard compatible basin swap can therefore be handled within that simple-work scope.
If the job extends to regulated water-service or sanitary-piping work—such as rerouting supply or discharge pipes—FixMove confirms the classification and arranges an appropriately licensed plumber for that portion. A basin relocation, wall opening, waterproofing, tiling or vanity rebuild is quoted separately rather than being presented as a basic replacement.
Get a written wash basin replacement quote
Send the existing basin photos, underside connections, dimensions, new basin model, property type and postcode. The reply should state labour, supplied parts, fittings to reuse or replace, removal and disposal scope, alteration work, visit fees and exclusions before the booking is confirmed.
Wash basin replacement FAQ
How much does wash basin replacement cost in Singapore?
FixMove's indicative labour guide is S$140–S$220 for a straightforward one-to-one wash basin replacement with compatible existing connections and access. Basin supply, tap, waste fitting, bottle trap, hoses, valves, countertop or cabinet work, pipe relocation and hidden repairs are separate unless listed in the written quote. A S$10 fuel surcharge applies per visit.
Can I buy my own wash basin for FixMove to install?
Yes. Before purchase, send the basin model or specification sheet together with photos and measurements of the existing basin, tap holes, waste outlet, mounting and any countertop cut-out. Installation can only be confirmed after compatibility is checked.
Are the tap and bottle trap included with basin replacement?
They are not automatically included. Reusing or replacing the tap, flexible hoses, pop-up waste, bottle trap, angle valves and other fittings is stated item by item in the written quote so the price boundary is clear.
How long does a wash basin replacement take?
A compatible one-to-one replacement is normally planned as one visit. The actual duration and number of visits depend on access, mounting, seized fittings, curing requirements, countertop or cabinet alteration and whether pipes must be moved. The appointment scope is confirmed after photo review.
Do I need a PUB Licensed Plumber to replace a wash basin?
PUB lists standard installation, replacement or removal of washbasins or sinks and their immediate below-basin traps as simple plumbing works. If the job extends into regulated water-service or sanitary-piping work, FixMove arranges an appropriately licensed plumber for that scope.
Can you move the basin to a new position?
A basin relocation is not a one-to-one replacement. It may involve water-supply and sanitary-pipe rerouting, wall or floor opening, waterproofing, tiling, cabinet or countertop work and an appropriately licensed plumber. It is surveyed and quoted as a separate project.
