Frequently Asked Questions

Common questions about Bathroom services in North York.

How much does a bathroom renovation cost in North York?

Bathroom renovations in North York range from $8,000–$15,000 for a cosmetic refresh to $20,000–$45,000 for a full gut-and-rebuild. High-end projects with custom tile, steam showers, and heated floors can exceed $60,000. We provide detailed written quotes broken down by scope.

How long does a bathroom renovation take in North York?

A cosmetic bathroom update in North York 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 North York?

In North York, 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 North York 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 North York. 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 North York 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 North York 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 North York that adds usable space and a modern look.
