Thornhill areas we work in

Thornhill straddles Vaughan and Markham — housing stock and permit process differ depending on which side you are on.

  • Bathroom renovation in Thornhill Woods & Uplands (Vaughan)

    Established 1980s–1990s detached and estate homes on the Vaughan side of Thornhill. Full bathroom rebuilds and double-vanity ensuites are common as original builder-grade fixtures reach end of life.

  • Bathroom renovation in German Mills & Bayview Glen (Markham)

    Larger detached homes on the Markham side. Primary ensuites with freestanding tubs, heated floors, and custom millwork are the typical brief.

  • Bathroom renovation in Richmond Hill border (Yonge & 16th)

    Mix of established detached and newer townhomes near the Thornhill–Richmond Hill line. Standard rebuilds and powder-room-to-3-piece conversions are typical.

  • Bathroom renovation in Promenade & Yonge corridor condos

    Mid- and high-rise condo buildings along Yonge Street near the Promenade. Condo board approval, IIC-rated underlay, and elevator booking apply the same way they do in Toronto and North York towers.

Bathroom renovation questions - Thornhill

How much does a bathroom renovation cost in Thornhill?
Most full bathroom renovations in Thornhill fall between $12,000 and $20,000, depending on materials, tiled area, and any layout or plumbing changes. Ensuites with double vanities run higher.
How long does a bathroom renovation take in Thornhill?

Do I need a permit for a bathroom renovation in Thornhill?
Thornhill straddles the City of Vaughan and City of Markham, so which building department handles your permit depends on which side of Bathurst Street or the 407 you are on. Plumbing relocation, electrical changes, or structural modifications require a permit from the relevant municipality; like-for-like fixture swaps generally do not. Condo boards along the Promenade require pre-approval regardless of permit status.

We renovate bathrooms across both sides of Thornhill - Thornhill Woods and Uplands in Vaughan, German Mills and Bayview Glen in Markham, and the Promenade condo corridor along Yonge - plus nearby Richmond Hill.
Are you a bathroom contractor near Thornhill?
Yes - Osoba Renos & Design operates from Mississauga and works regularly across York Region, including Thornhill, Vaughan, Markham, and Richmond Hill. Our in-house crew handles the full renovation, not subcontractors.
What upgrades are popular in Thornhill bathroom renovations?
Walk-in showers with premium tilework, heated floors, LED mirrors, custom glass enclosures, double vanities with quartz counters, freestanding tubs, and niches or benches are the most requested upgrades across both the Vaughan and Markham sides of Thornhill.
