How much does a bathroom renovation cost in Quebec in 2026?
Renovating a bathroom in Quebec usually costs between $8,000 and $45,000 before taxes. A mid-range full bathroom often lands between $18,000 and $30,000, and a luxury project with a curbless shower can reach $60,000. The room is small, but plumbing and waterproofing cost almost as much in 40 sq ft as in 80 sq ft, which explains the high price per square foot.
Quebec price ranges in 2026
Quebec market estimates, updated October 2026, before taxes (GST and QST extra). These are not guaranteed prices: costs vary by region, building and materials, and only a written quote based on your project gives an actual price.
| Project type | Price per sq ft | Typical budget |
|---|---|---|
| Powder room or half bath (toilet, sink) | $200 – $400 | $5,000 – $12,000 |
| Budget: prefab vanity, tub-shower, standard tile | $200 – $300 | $8,000 – $15,000 |
| Standard: glass shower, custom vanity, relocated plumbing | $350 – $550 | $18,000 – $30,000 |
| Luxury: curbless shower, heated floor, premium fixtures | $600 – $1,000 | $35,000 – $60,000+ |
What drives the price
- The shower: a curbless shower needs a full slope and waterproofing membrane, which costs more than a prefab base.
- Moving the toilet or drain, especially on a concrete slab.
- Tile: size, pattern and floor-to-ceiling installation multiply labour hours.
- Electric heated floors, the exhaust fan and recessed lighting.
- What is behind the walls: mould, old cast-iron pipes or a damaged subfloor found during demolition.
Mistakes to avoid
- Skimping on the exhaust fan: without outdoor venting, moisture ruins paint and grout within a few years.
- Tiling the shower without a continuous waterproofing membrane.
- Choosing fixtures after work starts: in-wall valves go in before the tile.
- Comparing quotes that do not count the same tile area.
How to get reliable quotes
- Specify the tile area (floor, walls, shower) and the tile size.
- Ask which waterproofing system will be used in the shower and whether it is warrantied.
- Have plumbing, electrical and the shower glass priced separately.
- Check that the contractor holds a valid RBQ licence for this type of work in the Régie du bâtiment du Québec registry.
- Insist on a detailed written quote and compare at least three quotes line by line, not just the total.
