    Why Builders & Owners Choose Perruzza

    Engineered before excavation — finished without compromise.

    A custom-home rough-in is the one stage of a build where small decisions become permanent. We sit at the table with the architect, builder, and homeowner during design development — heat-loss modeled, fixture-coordinated, and drawn onto the set before a single slab penetration is cut.

    Typical fixture count on our custom-home rough-ins: 18–40+ — balanced pressure across every line.

    Rough-In Scope We Design & Install

    Six layers of rough-in scope, engineered to the home — never to a template.

    From a 5,000 sq ft Kleinburg estate to a Toronto infill custom build, every Perruzza rough-in is detailed to the architectural set, the fixture schedule, and the mechanical room behind it.

    Whole-Home Rough-In Layouts

    Pre-construction supply, waste, and vent layouts engineered to architectural drawings for 2,500–12,000 sq ft custom estates across Vaughan and the GTA.

    • Reviewed against architectural set
    • DWV stack & vent design
    • Coordinated with HVAC + framing

    Our Design-Build Process

    Three engineered phases — backed by licensed Mechanical Contractors.

    From the first design review to the final high-end fixture install, every Perruzza custom-home project is delivered by fully licensed Mechanical Contractors — engineered, installed to code, and finished for the long run.

    01

    Design Review & Heat-Loss Modeling

    Our licensed Mechanical Contractors review the architectural set, run heat-loss calculations, vet the fixture schedule, and produce a coordinated rough-in design — before excavation.

    02

    Code-Compliant Rough-In

    Every supply line, DWV stack, manifold, and gas run is installed to Ontario Building Code, TSSA, and CSA standards — pressure-tested, photo-documented, and inspection-ready.

    03

    Finish & High-End Fixture Install

    After drywall, we return for the finish stage — luxury fixtures, freestanding tub fillers, steam systems, and the mechanical-room commissioning that ties it all together.

    Technical Specifications

    These are the design parameters we hit on a typical Vaughan or GTA custom-home rough-in — calibrated to the home's fixture schedule, finish materials, and the mechanical-room plant driving the system.
