Frequently asked questions
Does replacing a toilet need a permit?
A like-for-like swap is usually exempt. Moving the drain, adding a fixture or altering the vent is plumbing work that normally requires a permit and inspection.
Why is the installed price higher than the fixture price?
Labour includes removal, disposal, a new seal and supply, and levelling the fixture. Rotted flanges and damaged subfloor are the most common reasons a simple swap becomes a larger job.
How long does toilet installation take?
1-3 hours of work. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are fixture price, from builder-grade two-piece to wall-hung or bidet models; flange repair, riser or subfloor damage found after removal; rough-in distance and whether the drain has to move.
