Whether you're replacing a cracked kitchen sink, upgrading a bathroom vanity, or adding a sink as part of a second kitchen or basement bathroom, proper installation depends on more than just setting the new fixture in place. We check the condition of the existing drain, trap, and supply lines before installing a new sink, since older Scarborough homes often have plumbing beneath the sink that hasn't been touched in years.
We install kitchen sinks, bathroom sinks, and utility sinks, working with drop-in, undermount, and pedestal styles depending on the space and countertop. For sinks going into a basement bathroom or second kitchen, we also make sure the drain ties in properly with the ejector system or existing branch line so everything drains as expected.
Signs You Need Sink Installation
Signs it's time for a new sink installation:
Cracks or chips in the basin
A cracked sink can develop a slow leak over time, especially around drain fittings, and is generally not worth repairing.
Persistent leaks at the drain or trap
Recurring leaks around the drain assembly often point to worn seals or a trap that no longer fits properly.
Renovating the kitchen or bathroom
A countertop or vanity update is a natural time to install a new sink that matches the redesigned space.
Adding a sink for a new space
Second kitchens, basement bathrooms, and laundry rooms often need a new sink installed as part of the broader plumbing work.
Outdated or mismatched style
Some homeowners replace a functional but dated sink simply to update the look of a kitchen or bathroom.
How We Do It
What's involved in installing a new sink:
Step 1: Assessing the existing plumbing
We check the condition of the drain, trap, and supply lines beneath the current sink before beginning removal.
Step 2: Removing the old sink
We disconnect supply and drain connections, then carefully remove the old sink from the countertop or vanity.
Step 3: Preparing the new sink location
We confirm the new sink's dimensions fit the countertop cutout or vanity, adjusting mounting hardware as needed.
Step 4: Connecting drain and trap
We install a new trap and drain assembly, connecting it to the existing branch line or ejector system where applicable.
Step 5: Connecting supply lines
Hot and cold supply lines are connected to the faucet, with shut-off valves replaced if they're old or difficult to operate.
Step 6: Testing drainage and checking for leaks
We run water through the sink to confirm proper drainage and check every connection underneath for leaks.
Sink installations throughout Scarborough kitchens and bathrooms
In many bungalows and back-splits throughout Malvern and Woburn, under-sink plumbing has often been patched or partially replaced over the years, which means fittings under a sink don't always match each other in age or material. We take the time to assess this before installing a new sink, so the connections work together properly rather than combining old and new parts in a way that's likely to leak.
Sinks installed as part of a second kitchen or basement bathroom typically connect to a sewage ejector system, and we plan drain slope and trap placement with that connection in mind so the new sink drains reliably from day one.

We check every connection under the sink to confirm there are no leaks before considering the job done.
