Bathroom Renovation Contractor
Waterproofing is structural work, not a finishing step. It is what decides whether the room still looks right in ten years, and it is the part you will never see again once the tile goes on — so it gets done properly.
Overview
What the Work Involves
A bathroom renovation with ZaRRuS covers shower and tub installation, tile setting and waterproofing, vanities and storage, flooring and heated floor options, fixture and hardware installation, and ventilation and moisture control. The work is planned and installed as one job across Toronto and the GTA.
Showers, tile installation, waterproofing, vanities, flooring, fixtures, and drywall work are handled with careful attention to alignment, execution, and long-term performance.
Waterproofing is treated as structural work, not a finishing step — it is what decides whether the room still looks right in ten years.
Who this service is for
Homeowners doing a full bathroom rebuild, and anyone dealing with the consequences of a previous one that was waterproofed badly.
What shapes the scope and budget
- Layout. Keeping the toilet, shower and vanity in place avoids moving drains. The toilet is the least flexible fixture.
- Shower type. A curbless walk-in shower needs the floor recessed or carefully sloped; replacing a tub in place is simpler.
- Waterproofing and tile. The membrane system, tile size, pattern and how much wall is tiled drive most of the labour.
- Fixtures and glass. Thermostatic valves, niches, frameless glass and wall-hung vanities each add cost and lead time.
- Hidden conditions. Soft subfloor, old cast-iron or galvanized drains and moisture damage behind tile are dealt with when found.
- Comfort upgrades. Electric floor heat and a properly ducted exhaust fan are easiest to add while the room is open.
Every estimate is written line by line after a site visit. Where a number depends on a decision you have not made yet, it is shown as a range with the variable named.
How the work runs
- Site visit. Check the floor structure, drains, venting and, where possible, what is behind the existing tile.
- Layout and scope. Fixture positions are confirmed and the scope is written line by line.
- Selections. Tile, fixtures and vanity are chosen early; shower glass is measured after tile is set.
- Demolition and rough-in. Plumbing and electrical changes, framing for niches, and blocking for grab bars and accessories.
- Waterproofing and tile. The membrane goes on and is checked before any tile is set.
- Fixtures and walkthrough. Vanity, fixtures and glass installed, then the room is reviewed with you.

Questions
Bathroom Renovation Questions
How long does a bathroom renovation take?
A typical bathroom runs three to five weeks. Waterproofing and tile setting cannot be rushed without risking the result, and inspections where required add days rather than weeks.
What’s included in a bathroom renovation?
Demolition, waterproofing, tile setting, vanity and fixture installation, flooring, drywall and finishing. Structural changes or relocating drains sit outside the standard scope and are priced separately.
Do I need a permit for a bathroom renovation?
Replacing fixtures in place typically does not require a permit; relocating drains, altering structure or adding a new bathroom usually does. Your municipality makes the final call.
Can a bathtub be replaced with a walk-in shower?
Usually, yes. It depends on the drain location, the floor structure and how much slope the shower floor needs. That is checked at the site visit before a design is promised.
Do you install heated bathroom floors?
Yes. Electric in-floor heat is installed under the tile and needs its own circuit and thermostat, which are completed by a licensed electrician.
