What does bathroom plumbing rough in typically cost in New Brunswick?

Bathroom plumbing rough-in typically costs $2,500-$5,500 in New Brunswick, depending on the complexity of your layout and whether you're working with existing plumbing lines or starting from scratch.

Basic rough-in costs for a standard 3-piece bathroom (toilet, vanity, tub/shower) run $2,500-$3,500 when you're tying into nearby existing lines. This includes supply lines, drain rough-in, and venting. If you're adding a bathroom in a basement or area far from existing plumbing, expect $4,000-$5,500+ due to the additional pipe runs and potential need for a sewage ejector pump.

What drives costs higher in New Brunswick includes working around our older housing stock — many homes built in the 1970s-1990s still have cast iron drains or galvanized supply lines that may need replacement during renovation. Basement bathrooms often require ejector pumps ($800-$1,200 installed) since they're below the main sewer line. Access challenges in finished spaces add labor time, and winter conditions can delay material deliveries in rural areas.

The rough-in price typically includes materials (PVC drain pipes, copper or PEX supply lines, fittings) and labor for installation, but excludes fixtures, finish plumbing, and electrical work for exhaust fans or heated floors. Licensed plumber requirement is non-negotiable — all plumbing work in New Brunswick must be done by a TIS-licensed plumber, and you'll need a plumbing permit from Technical Inspection Services before work begins.

Timing considerations matter significantly. If you're renovating an existing bathroom, the plumber will need to coordinate with your general contractor since rough-in happens after framing but before drywall. Plan for 2-3 days of rough-in work, plus inspection time. TIS inspection is required before covering any pipes — schedule this promptly to avoid delays.

Smart planning tip: Have your plumber evaluate your existing plumbing during the estimate. Older homes often reveal surprises like undersized supply lines or drain issues that weren't apparent initially. Getting this assessment upfront helps avoid change orders mid-project.
