Dishwasher Installation Cost by Type

Ontario's Building Code and the Ontario College of Trades define which work requires a licensed plumber. For a standard dishwasher swap using existing connections, a skilled handyman can legally do the work. However, if new water supply lines, drain connections, or shutoff valves need to be installed or modified, a licensed plumber (Class 306A) is required. Using an unlicensed tradesperson for plumbing work beyond appliance connections may void your home insurance. (Serving North York, Ontario.)

What Affects the Final Price

A standard dishwasher swap (replacing an existing unit with a new one using the same connections) takes 1–2 hours for a licensed plumber or experienced handyman. This includes disconnecting and removing the old unit, connecting the new supply line and drain hose, levelling, securing to the cabinet, and testing. A new rough-in installation (no existing connections) typically takes 3–5 hours and requires a licensed plumber. Cabinet modifications add 1–3 hours depending on scope.
