Bathrooms are small rooms with big budgets. They pack plumbing, waterproofing, tile, electrical and ventilation into a tight footprint, and the work has to be done in the right order. Here is what bathroom renovations realistically cost across Toronto, Markham, Vaughan, Richmond Hill, Aurora and Newmarket, and what to know before you start.
How much does a bathroom renovation cost in the GTA?
| Bathroom type | Typical scope |
|---|---|
| Powder room | New vanity, toilet, flooring, lighting, paint, small updates |
| Standard full bathroom | Tub/shower, vanity, toilet, tile, fixtures, lighting, ventilation |
| Primary ensuite | Larger layout, walk-in shower, freestanding tub, double vanity, heated floors |
| Luxury or custom spa-style | Premium stone, steam or custom glass, layout changes, high-end fixtures |
Costs vary with size, finishes, home age and layout changes. A site visit is needed for a firm quote.
What drives the cost of a bathroom renovation?
- Layout changes. Moving a toilet, shower or tub means opening floors and walls, rerouting drains and often adding structural or subfloor work.
- Tile. Large-format porcelain, natural stone, mosaic patterns and floor-to-ceiling installations increase both material and labour costs.
- Shower and tub choices. A curbless walk-in shower with a linear drain and custom glass costs far more than a standard tub-shower combination.
- Fixtures and hardware. Prices for faucets, shower systems and vanities range enormously, from basic to designer.
- Waterproofing and ventilation. These are not optional. Proper waterproofing membranes and an adequately sized exhaust fan protect your home from moisture damage.
- Heated floors and smart features. Electric in-floor heating, heated towel racks and lighting controls add cost but are popular upgrades.
- Home age. Older GTA homes can hide galvanized pipes, outdated wiring, cast-iron drains or past water damage.

These components overlap by project and are not meant to be summed into a single number.
Do I need a permit for a bathroom renovation in Ontario?
It depends on the work. A cosmetic update such as a new vanity, paint and flooring generally does not require one. Permits are commonly required when you add or relocate plumbing fixtures or drains, make structural changes, or add a new bathroom. The Ontario Building Code applies, and each municipality, including Toronto, Markham and Vaughan, administers its own permit process. Electrical work should be done by a licensed electrical contractor. If you are unsure, check with your local building department. We will help you work out what applies.
How long does a bathroom renovation take?
A typical bathroom takes about 3 to 8 weeks on site, depending on size and complexity. Custom glass is often measured after tile is installed and takes additional time to fabricate, and special-order tile or vanities can have long lead times. Ordering early keeps the schedule on track. If permits are required, they add time before work begins.
Is it worth renovating a bathroom before selling?
Bathrooms and kitchens are commonly cited by real estate professionals as rooms buyers pay attention to, but results depend on your neighbourhood, buyer expectations and how dated the existing bathroom is. For a sale, a focused mid-range update is often more practical than a luxury spa renovation. A local realtor can tell you what makes sense for your street.
How can I keep a bathroom renovation on budget?
- Keep fixtures in their current locations. It avoids the most expensive plumbing changes.
- Choose one feature element. A statement tile on one wall, with simpler tile elsewhere, delivers impact at lower cost.
- Select fixtures before demolition. Rough-in dimensions depend on them.
- Do not skimp on waterproofing. Repairing hidden leaks costs far more than doing it right once.
- Plan for contingency.
