Plumbing · Sink Installation
Sink installation in Toronto and the GTA.
A new sink brings the faucet, the strainer, the trap, the supply lines and often a disposal with it. We fit the whole assembly and run water through it before we pack up.

What usually
turns out to be wrong.
Sink installation is mostly about what happens under the counter. The bowl has to be supported and sealed to the material above it, and everything below has to line up: the strainer, the tailpiece, the trap arm and the stub coming out of the wall. Change the bowl depth and that geometry changes with it, which is why a deeper sink so often means rebuilding the drain rather than reconnecting the old one. We plan for that from the start.
A deeper bowl than the old one
Modern sinks sit lower, and the trap arm that used to run downhill now runs level or uphill. Reconnecting the old drain to a deeper sink is the most common reason a new installation drains slowly.
An undermount that has dropped
A stone counter carries an undermount sink on clips and adhesive, and a full bowl is heavy. When the seal lets go, the first sign is a dark line along the stone or a damp cabinet edge.
The cutout doesn’t match the new sink
Sink openings are cut to one bowl, not to a size. A replacement that is a few millimetres out either sits proud of the counter or leaves the cut edge visible, and neither is fixed with sealant.
No room left for a disposal
A deep bowl with a disposal under it eats the space the trap needs, and in a shallow cabinet the unit ends up sitting on the shelf. That gets decided before the sink is ordered, not after.
The dishwasher hose was cut to the old sink
The hose ties into the sink waste, so a new bowl moves the connection it was cut for. Its length, the height it ties in at and where it clips up all get reset with the rest of the assembly.
Water damage already under there
Cabinet floors swell quietly. When we take an old sink out we often find a soft base under the trap from a leak nobody saw, and it is worth dealing with while everything is out of the way.
What the job includes.
The old sink out
Water isolated, the trap and supplies disconnected, the old bowl cut free of its sealant or clips, and the counter edge cleaned back rather than covered over.
Setting the new bowl
Drop-in sinks bedded and clipped down evenly; undermounts supported from below and sealed to the stone. Either way the bowl sits level so it drains to the strainer instead of to a corner.
Faucet and supplies
The faucet set on the deck with its gasket, shanks tightened from below, and new braided supply lines run to the stops rather than the old ones bent back into place.
The waste cut to the new depth
Strainers or a disposal flange fitted, then the tailpiece and the arm cut to suit the bowl rather than stacked out of extensions, and every joint pulled up and checked by hand.
Run before we leave
Both taps run hot and cold, the bowl filled and released to load the trap, the disposal run, and the cabinet watched dry underneath with a light on the joints.
How the visit goes.
- 01Measurements before anything is orderedSend us the cabinet width, the counter material and the model of sink. Bowl depth and cabinet size decide whether a disposal and a filtered tap will fit.
- 02The cabinet opened upWe clear the cupboard, look at the stops, the trap arm height and the state of the cabinet base, and tell you what the job actually involves before starting.
- 03Out, in, sealedOld sink out, new one set and sealed, faucet fitted, and the sealant left to hold before the bowl is loaded with water.
- 04Drain, disposal, testThe waste rebuilt to the new depth, the disposal wired and plumbed, then a full bowl released through it and every joint checked dry.

Often the fabricator sets an undermount bowl into the stone off site and leaves everything below it to someone else. That part is the plumbing: the faucet, the strainer or disposal flange, the trap rebuilt to the new depth, and the supplies. We work in after the counter is on, and we would rather see the sink model beforehand.
