Complete plumbing for new homes — from rough-in to final fixture. We partner with builders, general contractors, and homeowners across North Bay and Nipissing District to deliver code-compliant plumbing systems for custom homes, spec builds, and multi-unit projects.
North Bay Plumbers provides complete new construction plumbing services for residential builds across North Bay, Callander, Corbeil, Bonfield, and the wider Nipissing District. We handle every phase — rough-in plumbing below the slab and through the framing, municipal water and sewer connections, well and septic hookups for rural properties, finish plumbing and fixture installation, and radiant floor heating rough-in. Standard new home plumbing costs $8,000 to $15,000, while custom and luxury builds range from $15,000 to $30,000+ depending on fixture count and complexity. We coordinate all plumbing permits through the City of North Bay or Nipissing District building department and ensure every inspection passes the first time. Our service rate is $225 per hour. Call 705-482-1253 to discuss your build.
Building a new home in North Bay means getting the plumbing right the first time. Once drywall goes up, changes become expensive. Here's what we install and coordinate on every new build.
New construction plumbing happens in phases that align with your builder's schedule. We coordinate every step to keep the build on track and pass inspections the first time.
Before any pipe goes in the ground, we review the architectural and mechanical drawings with your builder or general contractor. We design the complete plumbing layout — fixture placement, pipe routing through the framing, drain slopes, vent stack locations, water heater positioning, and hose bib placement. For custom homes with multiple bathrooms, we optimize pipe runs to minimize material waste and maximize water pressure to every fixture. This planning phase catches conflicts with HVAC ducts, structural members, and electrical runs before they become expensive change orders on the job site.
Once the foundation is poured and framing begins, we install the underground drain lines below the basement slab — including the main building drain, floor drains, and bathroom rough-ins. We then connect to the municipal sewer system or septic tank. For properties on City of North Bay water, we run the water service line from the main at a minimum depth of 5 feet to clear the frost line. The rough-in phase includes all supply lines (PEX or copper), the complete drain-waste-vent system, gas lines for water heaters and fireplaces, and any radiant heating loops — all installed through the framing before insulation and drywall.
We schedule the rough-in inspection with the City of North Bay building inspector or the Nipissing District building department for rural properties. Before the inspector arrives, we pressure test all supply lines to verify zero leaks and water test the drain system to confirm proper slope and joint integrity. The rough-in inspection must pass before your builder can close the walls with insulation and drywall. Our work passes on the first inspection — no callbacks, no delays to your build schedule.
After drywall, painting, and flooring are complete, we return to install all fixtures. This includes toilets, bathroom vanities and sinks, kitchen faucets, shower valves and trim, bathtubs, dishwasher connections, laundry hookups, outdoor hose bibs, and any specialty fixtures like pot fillers or wet bar sinks. We connect the water heater, test every fixture for proper hot and cold delivery, verify drain flow rates, and check that all shut-off valves operate correctly.
We commission the entire plumbing system — running every fixture simultaneously to verify adequate pressure and flow, checking all drains under load, testing gas connections for leaks, and inspecting every joint and connection. We then schedule and pass the final plumbing inspection. Your builder gets a clean sign-off from the building department, and you get a fully warranted plumbing system with documentation of everything installed. We stand behind our work for the long term.
North Bay's building landscape includes everything from new subdivisions in the city to custom lakefront cottages on Lake Nipissing's South Shore. Each type of build has its own plumbing requirements, and we know them all.
New residential development in North Bay continues to expand, with subdivision builds from spec home builders like Loxton Homes requiring efficient, repeatable plumbing systems that meet Ontario Building Code requirements and pass City of North Bay building inspections without delays. We work with multiple builders simultaneously, coordinating rough-in and finish schedules across several homes to keep projects on track. Our experience with standard subdivision layouts means faster installation, fewer material callbacks, and predictable pricing for builders.
Custom homes in Callander and along Lake Nipissing's South Shore often feature 3 to 5 bathrooms, radiant floor heating, outdoor showers, and high-end fixtures that require careful plumbing design. These builds demand more complex multi-zone water systems, larger water heaters (or tankless units), and PEX manifold systems that deliver consistent pressure to every fixture even when multiple showers run simultaneously. We work directly with homeowners and architects to translate their vision into a plumbing system that performs flawlessly.
North Bay's frost line sits at 4 to 5 feet below grade — significantly deeper than southern Ontario. Every water service line and sewer connection must be buried below this depth to prevent freezing. Municipal water connections through the City of North Bay require coordination with the public works department, while underground routing on the property must avoid conflict with other utilities, septic fields, and future landscaping. We've been installing underground services in this climate for years and know exactly how to protect your investment from freeze damage.
Properties in Corbeil, Bonfield, and throughout the rural Nipissing District rely on private wells and septic systems rather than municipal services. New construction plumbing for these builds includes pressure tank installation, water treatment systems for the high-mineral well water common in the region (iron, manganese, hardness), properly sized septic connections, and sometimes sewage ejector or grinder pump systems where the septic tank elevation doesn't allow gravity drainage. We coordinate with well drillers and septic installers to ensure the entire water system works as a unit.
In North Bay's climate, PEX has become the dominant supply pipe material for new construction — and for good reason. PEX expands slightly when water freezes, making it far more resistant to burst pipes during our -30°C to -40°C winters. It's faster to install than copper (reducing labour costs), quieter (no water hammer), and 30-40% less expensive in materials. We recommend PEX with a home-run manifold system for most new builds, with copper reserved for exposed runs where appearance matters or specific commercial requirements demand it. Both materials meet Ontario Building Code standards.
Every new construction plumbing installation in North Bay requires permits and inspections through the City of North Bay Building Services department — or the Nipissing District building department for properties outside city limits. The Ontario Building Code governs pipe sizing, venting requirements, fixture spacing, drain slopes, material standards, and backflow prevention. We handle the complete permit process: application submission, rough-in inspection scheduling, and final inspection coordination. Our installations are designed to pass inspection the first time, keeping your build on schedule and your builder happy.
New construction plumbing is one of the largest mechanical trades costs in a new home. Here's what drives the price and what you can expect for different types of builds.
A standard 3-bedroom, 2-bathroom new home typically costs $8,000 to $15,000 for complete plumbing — rough-in through finish. Custom homes with multiple bathrooms, radiant floor heating, or luxury fixtures range from $15,000 to $30,000+. The final price depends on fixture count, pipe material, number of bathrooms, and whether you're connecting to municipal services or well and septic. We provide a detailed written quote based on your blueprints before any work begins.
For most new builds in North Bay, we recommend PEX supply lines. PEX is freeze-resistant (it expands slightly instead of bursting), costs 30-40% less than copper in materials and labour, and eliminates water hammer noise. Copper is still a good choice for exposed runs where appearance matters. Both are Ontario Building Code approved. We'll discuss the options and help you choose based on your budget and preferences.
North Bay's frost line sits at 4 to 5 feet below grade. Water supply lines must be buried at least 5 feet deep to prevent freezing, and sewer lines need adequate depth plus proper slope for gravity flow. We ensure all underground connections exceed the minimum depth requirements specified by the City of North Bay and the Ontario Building Code — because frozen water mains on a brand-new home are unacceptable.
Yes — all new construction plumbing in the City of North Bay and Nipissing District requires a plumbing permit and at least two inspections: rough-in (before walls are closed) and final (after fixtures are installed). We handle the entire permit process — application, scheduling, and inspection coordination — so your builder doesn't have to. Our work passes inspection the first time.
Absolutely. For rural properties in Corbeil, Bonfield, Callander, and throughout Nipissing District, we design and install plumbing systems for well water supply and septic disposal. This includes pressure tanks, water treatment for high-mineral well water, septic-ready drainage, and pump systems where gravity drainage isn't possible. We coordinate with well drillers and septic installers to ensure seamless integration.
The rough-in phase (underground and through framing) takes 3 to 5 days for a standard home. The finish phase (fixtures and final connections) adds another 2 to 3 days. Custom homes with 4+ bathrooms, radiant heating, or complex layouts take proportionally longer. We coordinate our schedule with your builder to stay on the critical path — we show up when we're supposed to and don't hold up the next trade.
