New Plumbing Rough-Ins in Orillia & North Bay — Done to Code, Laid Out for Long-Term Reliability

Behind every working faucet, flushing toilet, and draining tub is a properly roughed-in plumbing system — installed before the walls go up.

At Poly-B Plumbing, we provide licensed plumbing rough-ins for new builds, additions, and renovations across residential and light commercial projects. Every pipe, fitting, and drain is installed to Ontario Building Code, with long-term performance and future access in mind.

Our Rough-In Process

Step 1

Review Plans & Layout

We study your blueprints, building plans, or sketches. For renos, we assess existing plumbing and layout options.
Step 2

Confirm Code Requirements

We apply Ontario Building Code and any local municipal requirements for slope, venting, fixture units, and access.
Step 3

Install Water and Drain Lines

We use premium materials (copper or PEX, ABS or PVC), mounted securely and with the correct slope, spacing, and supports.
Step 4

Pressure Testing and Inspection

Once installed, we pressure-test all water lines and drain systems, and coordinate rough-in inspections as needed.
Step 5

Site Coordination

We coordinate with other trades and leave the job site clean and ready for the next stage.

Frequently Asked Questions

Do you handle permits?

We coordinate with your contractor or handle permitting directly if we’re managing the job.

Can you do layout planning for us?

Yes — we help with pipe routing, drain location, and venting design as part of the quote process.

How long does a rough-in take?

A single bathroom rough-in usually takes 1–2 days. Full-home jobs range from 2–5 days depending on access and scope.

What if framing changes mid-job?

We’re flexible. We can adjust runs or reroute based on changes — always staying within code.
