How Much Does a Bathroom Renovation Cost in the GTA? (2026)
What a bathroom renovation costs across the GTA in 2026: price ranges for powder rooms to ensuites, what drives cost, timeline, and how design-build keeps the budget honest.
In 2026, most bathroom renovations across the Greater Toronto Area land between $15,000 and $45,000, depending on the size of the room and the scope of the work. A simple powder room refresh can come in under $15,000, while a full primary ensuite with a custom shower, heated floors, and moved plumbing can climb past $50,000. The single biggest cost driver is not the tile you choose. It is whether the layout stays put or moves, and how carefully the wet areas are waterproofed.
Here is an honest breakdown of what you can expect to pay, what makes the number go up or down, and how a proper process protects both your budget and your home.
Bathroom Renovation Cost by Type in the GTA (2026)
Every home is different, but these ranges reflect what quality-focused bathroom renovations actually cost across the GTA right now. They assume real workmanship, code-compliant rough-ins, and mid to upper-mid finishes, not builder-basic materials.
| Bathroom type | Typical scope | 2026 cost range |
|---|---|---|
| Powder room | Vanity, toilet, lighting, paint, flooring, no shower or tub | $8,000 to $18,000 |
| Main / guest bath | Tub or shower, tile surround, vanity, new fixtures, same layout | $18,000 to $35,000 |
| Primary ensuite | Custom shower, freestanding tub, double vanity, heated floors | $35,000 to $65,000+ |
| Layout change (any type) | Add $8,000 to $20,000 when plumbing or walls move | Varies |
Where you land inside these ranges depends on the decisions below. The good news is that most of them are within your control once you understand what drives the price.
What Drives the Cost of a Bathroom Renovation
A bathroom is the most plumbing-dense, moisture-heavy, and detail-intensive room in a home for its size. Small choices compound quickly. These are the factors that move the number the most.
- Moving plumbing. Keeping the toilet, sink, and drain where they are is the cheapest path. Relocating a drain, adding a second sink, or moving the shower means opening walls or floors and re-running supply and waste lines. This is often the largest hidden cost.
- Layout changes. Removing a wall, converting a tub to a walk-in shower, or reworking the footprint adds framing, electrical, and sometimes structural work on top of the plumbing.
- Waterproofing. Done properly, this is a line item you will never see again, which is exactly the point. Cutting it is how you end up rebuilding the same bathroom twice.
- Tile. Material cost varies widely, but the bigger driver is labour. Large-format tile, mosaics, herringbone, and full-height walls all take more time to set level and true.
- Fixtures and fittings. Faucets, showers, toilets, and vanities span an enormous price range. A quality-focused build spends where it counts, on valves and the shower system, and stays sensible elsewhere.
- Ventilation and electrical. A properly sized exhaust fan, pot lights, GFCI protection, and a heated floor mat all add cost and all matter for a bathroom that lasts.
Why Proper Waterproofing Matters More Than Anything
If you take one thing from this article, take this: waterproofing is the difference between a bathroom that lasts twenty years and one that fails in three. Water is patient. It finds every gap behind the tile, and by the time you see it on a ceiling below, the damage is already done inside the wall.
A correct wet-area assembly means a continuous waterproof membrane behind the tile, proper sloping to the drain, sealed corners and penetrations, and the right substrate, not ordinary drywall, anywhere water can reach. This is invisible work. Nobody photographs it for a magazine. That is precisely why it gets skipped by teams competing on price, and why we never do.
Every Andare Homes bathroom is built to the Ontario Building Code and backed by our 2-year workmanship warranty. When the waterproofing is done right the first time, that warranty is a formality rather than a lifeline.
The Design and Permit Process
A bathroom that photographs beautifully starts on paper, not at the tile store. Our in-house design team is the differentiator here. Because design and construction sit under one roof, the person drawing the layout is talking daily to the person who will build it, so what gets designed is what actually gets built, on budget.
The design phase typically covers:
- Measuring the existing space and confirming what can and cannot move
- A layout that solves the actual problem, whether that is storage, a cramped shower, or a dated footprint
- Fixture, tile, and finish selections with real pricing attached, so there are no surprises later
- A fixed scope and schedule before any demolition begins
Most straightforward bathroom renovations do not require a building permit, but any electrical work must be done to code and any structural or major plumbing change may need one. We handle that determination and any required permits as part of the process, so it is never left on your plate.
A Realistic Timeline
Homeowners are often surprised that a small room takes real time. The reason is sequencing. Waterproofing has to cure. Tile has to set before grout. Paint needs the room dry. You cannot rush chemistry.
- Design and selections: 2 to 4 weeks
- Permits, if required: 1 to 3 weeks, often overlapping design
- Powder room build: 1 to 2 weeks on site
- Main bathroom build: 2 to 4 weeks on site
- Primary ensuite build: 4 to 6 weeks on site
A team that promises your ensuite in a week is either skipping cure times or working on several jobs at once and cutting corners on yours. Honest timelines are a quality signal.
How Design-Build Keeps the Budget and Schedule Honest
The most common way a renovation goes over budget is not one big surprise. It is a series of small handoffs, between a designer who does not price the work, a contractor who did not see the drawings, and a homeowner caught in the middle relaying messages. Every gap in that chain is where a change order is born.
Design-build closes those gaps. One accountable team owns the drawings, the pricing, the schedule, and the workmanship. That means:
- The budget you approve reflects the bathroom that actually gets built, because the builder priced the design
- One point of contact for every question, not a finger-pointing match between trades
- Selections locked before demolition, so you are not deciding on tile with the walls already open and the clock running
- Fewer change orders, because problems are caught on the drawing, not in the wall
The same discipline that keeps a bathroom honest is what carries a larger project. If you are weighing a bathroom against a bigger scope, the same team handles kitchen renovations and whole-home renovations, and you can see the standard of finish across our projects.

Frequently Asked Questions
How much does a small bathroom renovation cost in the GTA? A powder room or small guest bath typically runs $8,000 to $18,000 in 2026, assuming the layout stays the same. Costs rise quickly if plumbing moves or you add a shower where there was none.
What is the most expensive part of a bathroom renovation? Usually the plumbing and layout, not the finishes. Moving a drain or reconfiguring the room means opening walls and floors, which drives both labour and time. Custom shower systems and heated floors add cost, but relocating fixtures is the bigger swing.
Do I need a permit to renovate my bathroom in the GTA? Many like-for-like bathroom renovations do not require a building permit, but electrical work must always meet code, and structural or major plumbing changes may need one. We assess this and pull any required permits as part of the project.
How long does a bathroom renovation take? Plan on 1 to 2 weeks on site for a powder room, 2 to 4 weeks for a main bathroom, and 4 to 6 weeks for a primary ensuite, plus a few weeks up front for design and selections. Proper waterproofing and tile need cure time that cannot be rushed.
