Bathroom Renovation Cost in Quebec

Bathroom Renovation costs in Quebec differ from the national baseline mainly because of local labor rates. Carpentry labor in Quebec runs about 15% above the national average carpenter wage (Job Bank, NOC 72310, a disclosed proxy for bathroom renovation trades), the largest provincial uplift, raising the labour share of a bathroom renovation.

Quebec's hard freeze-thaw winters age the plumbing in Montreal's plex buildings and the province's deep stock of pre-war housing, so bathroom guts commonly expose cracked cast-iron stacks shared between units — coordinating and replacing that common drainage, plus insulating supply lines against the deep frost, drives much of the local renovation premium.

Quebec municipalities require a renovation permit (permis de rénovation) when a bathroom project moves plumbing or walls — typically $100-$350 — and the work itself must be performed by contractors holding the appropriate Régie du bâtiment du Québec (RBQ) licence. Quebec charges 5% GST plus 9.975% Quebec Sales Tax (QST), about 14.975% combined, on bathroom fixtures, tile, and renovation labour.
