Why Choose Kar Reno for Your Thornhill Bathroom Renovation
Thornhill sits right next to our North York base, and its homes range widely: mid-century houses in Royal Orchard and Bayview Glen, character homes in Old Thornhill, and newer family homes in Thornhill Woods. Kar Reno brings 20+ years of experience to bathroom renovations across Thornhill, from compact main bathrooms to large master ensuites.
Thornhill is split between two cities. West of Yonge Street is the City of Vaughan, and east of Yonge is the City of Markham, so the permit office depends on your address. We know both processes and handle the permit for you whenever plumbing moves or a new bathroom is added.
What Makes Our Thornhill Bathroom Renovations Stand Out
- One dedicated project manager as your single point of contact for your bathroom renovation, from start to handover.
- Our in-house design team creates a 3D render of your bathroom before work begins, so there are no surprises later.
- All bathroom permits are handled by our team, start to finish.
- Wholesale pricing on every material — tile, fixtures, vanities — with the savings passed straight to you.
- One fixed-price contract with a fully itemized scope, materials list, and timeline, all upfront.
Types of Bathroom Renovations We Offer in Thornhill
Combined Shower and Tub Bathroom
Perfect for growing families, our combined shower and tub bathrooms blend everyday practicality with a polished, spa-inspired finish. Deep soaker tubs, sleek tile surrounds, and space-smart layouts make the most of every square foot. Combined shower and tub renovations in Thornhill typically range from $12,000–$20,000 depending on fixtures and finishes.
Walk-In Shower Bathroom
Step into a sleek, curbless walk-in shower with frameless glass, linear drains, and large-format tile for a clean, modern look. Built for accessibility and everyday ease without sacrificing style. Walk-in shower renovations in Thornhill typically range from $15,000–$25,000 depending on tile selection and glass configuration.
Master Bathroom
Transform your ensuite into a luxury private retreat with heated floors, floating vanities, frameless glass showers, large-format tile, and premium finishes. Custom master bathroom renovations in Thornhill often range from $25,000–$50,000+ depending on the size of the space, material selections, and custom features. See our bathroom cost guide for a full breakdown.
Powder Room
Make a bold first impression with a beautifully finished powder room. Statement wallpaper, designer fixtures, and space-efficient vanities turn even the smallest room into a showpiece. Powder room renovations in Thornhill typically range from $8,000–$15,000 depending on finishes and layout.
Before & After: A Recent Kar Reno Bathroom Project
After
Our renovation team transformed the space into a bright, spa-inspired bathroom. A sleek walk-in shower replaced the old tub-shower combo, a floating vanity added a modern touch, and heated flooring brought everyday comfort. Kar Reno designed every detail, from tile to lighting, to give the homeowners a space that feels like a private retreat.
Before
This bathroom was dated and cramped, with a worn tub-shower combo, outdated tile, and dim lighting that made the space feel smaller than it was. Like many older homes across the GTA, the layout no longer suited the homeowners’ needs. Storage was limited, grout was stained and cracking, and moisture damage had started to appear around the tub, a space the homeowners avoided rather than enjoyed.

Thornhill Bathroom Renovation FAQs
Most bathroom renovations in Thornhill cost between $12,000 and $25,000. Powder rooms typically run $8,000–$15,000, and master ensuites range from $25,000 to $50,000+, depending on size, layout changes and finishes.
It depends on your address. Thornhill west of Yonge Street is part of the City of Vaughan, and east of Yonge is part of the City of Markham. Cosmetic updates usually don’t need a permit, but moving plumbing or adding a bathroom does. We handle the application with the right city.
Old Thornhill is a heritage conservation district. Heritage rules mainly cover the outside of a home, such as windows, doors and additions, so interior bathroom renovations usually aren’t affected. If your project changes anything on the exterior, we check the heritage requirements first.
Yes. In homes from the 1960s and 1970s, we often find old plumbing, uneven floors or hidden moisture damage once the old tile comes off. We check for these during the estimate and plan for them, so there are fewer surprises during the project.
Most full bathroom renovations take 1–2 weeks. Larger ensuites or older bathrooms that need plumbing upgrades can take longer. You get a written schedule before work begins.
Yes. Kar Reno is a licensed, HomeStars award-winning contractor with $2M liability insurance and WSIB registration. All completed work comes with a 2-year warranty.
