Basement Bathroom Addition in Guelph

Adding a bathroom where one doesn't exist means running new drain, vent and supply lines — often requiring a sewage ejector pump if the basement floor sits below the main drain line, which is common in older Guelph homes.

Newer south-end builds are frequently roughed-in for a basement bathroom already (a capped drain stub-out), which meaningfully lowers cost since the plumbing run is already in place.

A plumbing permit is required regardless of whether the home was pre-roughed-in.
