In short: a complete bathroom (demolition, waterproofing, plumbing, glass shower, heated floor, custom vanity, tiling) costs $20,000 to $45,000 in Montreal in 2026. Moving plumbing, enlarging the room or choosing high-end materials pushes the budget to the top of the range.
The items that make up the price
| Item | Typical share of budget | Notes |
|---|---|---|
| Demolition and disposal | 5 to 8% | Higher with a tiled built-in tub and a concrete floor |
| Plumbing and electrical | 15 to 25% | Moving a drain or adding a circuit for the heated floor |
| Waterproofing, shower and tub | 20 to 30% | Custom glass shower and freestanding tub above average |
| Tiling and heated floor | 15 to 20% | Tile format, mosaic, shower niche |
| Vanity, counter and mirror | 15 to 25% | Custom vanity built in the workshop |
| Paint, accessories, ventilation | 5 to 10% | Quiet fan, grab bars, lighting |
Three common scenarios
- Refresh: resurfaced vanity, new counter, faucet and paint, $2,500 to $6,000, one to two days.
- Complete renovation without moving plumbing: $20,000 to $45,000, 3 to 4 weeks.
- Reconfiguration with relocated plumbing or enlargement: top of the range or more, 4 to 6 weeks, permit required.
Do I need a permit?
Not to replace fixtures, the vanity and tiling in the same place. A borough permit is required if you move plumbing, alter a load-bearing wall or add a bathroom in the basement. We prepare the application with the quote.
What is worth the investment
The heated floor, the curbless glass shower and a vanity with well-planned storage are the three elements owners regret least. Large-format tile reduces the grout to maintain, and a properly sized quiet fan protects your investment against humidity.
