Bathroom Renovation in Kitchener

Bathroom Renovation Experts

A bathroom renovation should feel controlled and predictable — not chaotic. At Interior Systems Group, we plan the work, sequence it properly, and finish to drawings, code, and inspection standards across Kitchener–Waterloo, Cambridge, Guelph, London, Hamilton, and Milton. With $5M liability insurance, WSIB coverage, and a 12‑month workmanship warranty, you get price certainty, schedule discipline, and a professional finish from a small, accountable team.

What Is Bathroom Renovation?

A bathroom renovation updates or rebuilds your bath to improve layout, safety, and style while protecting against moisture. Our process starts with a clear scope and a realistic schedule. We handle demolition with dust control, assess framing and subfloor, then complete plumbing and electrical rough-ins to code with GFCI protection. We use proven waterproofing systems (such as Schluter/Kerdi for showers), set tile with laser accuracy and leveling systems, install tubs, vanities, and fixtures, and ensure proper ventilation with correctly sized exhaust fans. Every step is planned — from substrate prep and sloped shower pans to caulking and sealing — to deliver a durable, clean finish. We coordinate inspections, keep you informed, and close out fully so there are no loose ends.

When Should You Consider Bathroom Renovation?

Consider renovating if you’re seeing cracked grout, soft subfloors, recurring leaks, swelling trim, musty odors, dated fixtures, poor lighting, or a layout that no longer fits your household. Many homeowners in Kitchener–Waterloo update bathrooms every 10–20 years, or sooner after water damage, before listing a home, or when accessibility needs change. Seasonal timing can help: winter planning often leads to faster material lead times, while spring and summer are popular build windows. Typical timelines for a standard bathroom range from 10–20 working days depending on scope; complex tile patterns, custom glass, or layout changes can extend to around 30 days. We set a disciplined schedule up front and keep it — with a clean, documented closeout at the end.
