Complete Bathroom Renovation Guide

Planning, budgeting, layout decisions, materials, and contractor selection for a successful bathroom renovation in Toronto and the GTA.

Step 1 — Define the Scope

Before anything else, decide what you're changing. A cosmetic refresh (new fixtures, paint, vanity) is very different from a full gut-and-rebuild. Scope determines your budget, timeline, and whether you need permits.

Step 2 — Set a Realistic Budget

Bathroom renovation costs in Toronto (2024):

Cosmetic update (fixtures, vanity, paint): $5,000–$12,000
Mid-range full renovation: $15,000–$30,000
High-end with custom tile, heated floor, steam shower: $35,000–$60,000+

Set aside 10–15% contingency — old plumbing surprises are common.

Step 3 — Layout and Plumbing

Moving plumbing is the single biggest cost driver. Keeping the toilet, shower, and vanity in the same locations can save $3,000–$8,000 versus relocating them. If the space is functional, work with the existing layout.

Step 4 — Material Selection

Tile

Porcelain tile is the most durable choice for floors and shower surrounds. Large-format tiles (24"×24" or larger) make small bathrooms look bigger. Natural stone looks beautiful but requires sealing and more maintenance.

Vanity and Storage

Floating vanities visually expand the floor. For storage, a combination of under-vanity cabinets and a medicine cabinet handles most needs without taking wall space.

Fixtures

Mid-range fixtures from Moen, Delta, or Kohler offer the best durability-to-cost ratio. Avoid ultra-budget fixtures — they often need replacement within 3–5 years.

Step 5 — Permits

In Toronto, you need a permit for: moving walls, relocating plumbing, adding electrical circuits. You don't need a permit for: replacing fixtures in the same location, new tile, new vanity.

Common questions about Bathroom services in Toronto and the GTA.

How much does a bathroom renovation cost in Toronto & GTA?

How long does a bathroom renovation take in Toronto & GTA?

A cosmetic bathroom update in Toronto & GTA takes 1–2 weeks. A full renovation with plumbing and tile work takes 3–5 weeks. Projects involving moving walls or relocating plumbing can take 6–8 weeks. We provide a clear timeline before work begins.

Do I need a permit for my bathroom renovation in Toronto & GTA?

In Toronto & GTA, permits are required when you're moving plumbing, adding electrical circuits, or removing walls. Replacing fixtures in the same location, new tile, or a vanity swap typically don't require permits. We pull all required permits and coordinate inspections.

Can you move the toilet or shower to a different location?

Yes, but relocating plumbing is the biggest cost driver in bathroom renovations. Moving a toilet or shower requires breaking the concrete floor (in basements) or rerouting drain lines — adding $3,000–$10,000 to the project. We advise on cost-effective alternatives where possible.

What tile is best for bathroom floors and shower walls?

Porcelain tile is the most durable and water-resistant choice for both floors and shower walls in Toronto & GTA homes. Large-format tiles (24×24") make small bathrooms look bigger. Natural stone is beautiful but requires sealing and more maintenance.

Do you handle electrical and plumbing in bathroom renovations?

Yes. We coordinate all trades including licensed electricians and plumbers as part of our full-service renovation approach in Toronto & GTA. You deal with one contractor — we handle the entire scope and scheduling.

What is the best ventilation solution for a bathroom?

Ontario Building Code requires mechanical ventilation in all bathrooms without operable windows. We install Energy Star–rated exhaust fans sized to the room's CFM requirements. Proper ventilation prevents mould, protects drywall, and extends the life of your finishes.

Can you add a bathroom to my basement?

Yes. Basement bathroom additions in Toronto & GTA typically require breaking the concrete floor to tie into the drain system (or installing a sewage ejector pump). Costs range from $8,000–$20,000 depending on complexity. We handle permits, rough-in plumbing, and all finishes.

What's included in a full bathroom renovation?

Our full bathroom renovations in Toronto & GTA include: demolition, waterproofing, plumbing rough-in, electrical, tile installation, vanity and fixture installation, glass shower enclosures, accessories, painting, and final inspection. We handle everything from start to finish.

How do I choose between a walk-in shower and a bathtub?

If you have only one bathroom, keep the tub — it helps with resale value and is needed for bathing children. If you have a second bathroom, converting the tub to a walk-in shower is a popular upgrade in Toronto & GTA that adds usable space and a modern look.
