A chipped or cracked bathroom sink stands out in an otherwise clean bathroom. Whether it’s a chip on the rim of a ceramic pedestal basin, a crack in a composite vanity sink or a stain in a white inset bowl, surface damage to bathroom sinks is noticeable and off-putting. Professional sink repair addresses these issues without the disruption and cost of sink replacement — which typically involves disconnecting plumbing, sourcing a matching replacement and replumbing.
Types of Bathroom Sink We Repair
Ceramic Pedestal Basins
The classic white vitreous china pedestal basin is the most commonly repaired sink type. Chips on the rim or inner bowl are extremely common and typically cause by dropping a hard object into the sink. The chip exposes the cream or buff body clay beneath the white glaze. Professional repair fills the chip with colour-matched glazing material and finishes flush with the surrounding glaze.
Under-Mount and Countertop Sinks
Under-mount ceramic or composite sinks built into vanity units are harder to replace because they’re bonded to the worktop above them. Repair is significantly less disruptive than replacement.
Composite and Solid Surface Sinks
Composite sinks — made from resin-bound mineral composite — can chip or crack. Repair uses colour-matched composite-compatible materials. Corian and other solid surface sinks that are bonded to a solid surface worktop can also be repaired without disturbing the worktop joint.
Enamel Sinks (Steel and Cast Iron)
Older vitreous enamel sinks — on steel or cast iron — are repaired using enamel-compatible materials. As with enamel baths, early repair of chips prevents rust spread in the exposed metal beneath.
Stained or Discoloured Sinks
Mineral staining (hard water deposits, rust marks from taps), dye staining and age-related discolouration can often be addressed through professional cleaning and, where necessary, surface treatment. True staining that has penetrated the glaze or composite may require surface repair rather than just cleaning.
Sink Repair vs Replacement: The Case for Repair
Replacing a bathroom sink involves: turning off the water supply, disconnecting the waste, unscrewing the basin from the wall or disconnecting from the vanity unit, sourcing a matching or compatible replacement (discontinued designs can be impossible to match), replumbing and resealing. Total cost including labour is typically £300–£800+. Professional chip repair typically costs £100–£300 and takes a few hours in a single visit. For isolated damage, repair is almost always the better choice.
