When sink work is the right call:
- Replacing a damaged or stained sink.
- Renovating the kitchen or bathroom.
- Adding a sink in a basement, laundry, or wet bar.
- Switching from drop-in to undermount.
- Upgrading from single-bowl to double-bowl (or reverse).
- Replacing alongside a faucet or countertop installation.
Sink installation cost
Pricing depends on sink type (drop-in, undermount, farmhouse), whether it is supplied or not, and what other work happens at the same time. Drop-in replacements stay in the lower range. Farmhouse and undermount installs are higher because of cabinet work and seal detail.
What to share when you call
- Sink type and size.
- Whether the sink is on hand or being supplied.
- Whether faucet, garbage disposal, or shutoff replacement is part of the scope.
- Cabinet style (open, vanity, custom).
- Photos of the existing sink and supplies.
- Renovation timing if part of a larger project.
Toronto context
Sink installs in Toronto kitchens and bathrooms hinge on the rough-in. Pre-1980 cast-iron sink drains often need replacement at the same time — the new sink connects to a new branch in PVC, not a cobble of cast-iron and ABS adapters that leak two years later.
What to confirm before approving sink work
- Shutoffs and supply lines should be inspected — old ones often need replacement.
- Drain alignment should be verified before the new sink is set.
- Final installation should be leak-tested under sustained flow.
Useful info on the call: sink type, supply readiness, and other fixtures involved.
Frequently asked questions
Can I replace my drop-in with an undermount?
Yes if the countertop supports it. Solid surface, stone, or laminate countertops have different requirements. Tile countertops often do not work well with undermount.
Do I need a new faucet at the same time?
Often yes — faucet hole spacing and configuration may not match between old and new sinks. Replacing both at the same time is usually cleaner.
Will the existing P-trap fit?
Usually with adjustment. New sink heights and drain locations sometimes require new trap fittings.
Can I install a garbage disposal at the same time?
Yes. Add it to the booking so the disposal mounting and electrical are ready.
