Bathroom Renovations in the Greater Toronto Area
A bathroom renovation is the highest-stakes small room in your home: get the waterproofing wrong and you pay for it twice. Blackstone General Contracting builds GTA bathrooms — ensuites, main baths, and powder rooms — with proper membrane waterproofing, sloped shower bases, and licensed plumbing, so the finish that looks good today stays sound for decades.
Our bathroom scope covers demolition, moisture-resistant framing and backer board, membrane or foam waterproofing systems, custom tile, glass shower enclosures, vanities, and fixtures. We coordinate licensed plumbers and electricians for fan venting, heated floors, and pot lights so every element passes inspection.
Because bathrooms hide their most important work behind the tile, we document the waterproofing and rough-in stages before we close the walls. That record protects you and is part of why our work is covered by a 12-month limited workmanship guarantee.
