Questions to ask before a bathroom renovation
A bathroom renovation involves several trades working in sequence — and plumbing is one of the first things that has to be decided, because rough-in work happens before walls are closed. Getting clarity on the plumbing questions early avoids costly changes later.
What is the current rough-in configuration?
Before finalizing your fixture selection, know the existing rough-in dimensions — the position of drain and supply connections relative to the wall. Toilet rough-in distance (typically 12" in most homes), faucet hole spacing, and drain position for the tub or shower all affect which fixtures will work without significant rough-in changes.
What changes to the plumbing are planned?
Moving a toilet, adding a fixture that doesn't currently exist, or relocating the shower to a different wall are all significant plumbing changes that affect rough-in scope, cost, and timing. Clarify the full scope of plumbing changes before finalizing the budget.
Will a permit be required?
In Winnipeg, plumbing work that involves moving or adding supply or drain lines typically requires a permit and inspection. Confirm with your plumber whether a permit is needed for the work being done. Unpermitted plumbing work can create complications during sale or insurance claims.
What is the condition of the existing plumbing?
If the home is older and hasn't had plumbing work done recently, opening walls for a bathroom renovation can reveal aging supply lines, corroded drain fittings, or galvanized pipe that should be replaced while the walls are already open. Ask your plumber to assess what's there before walls are closed.
How does plumbing coordinate with other trades?
The sequence matters: framing, rough plumbing, electrical rough-in, insulation, drywall, tile, and then fixture installation. Rough plumbing has to be inspected before walls are closed. Fixture installation happens after tile is complete. Ask your plumber to clarify timing at the outset so all trades understand the sequence.
