About Plumbing Rough-Ins

What is a Plumbing Rough In?

A plumbing rough-in refers to the installation of various plumbing lines, pipes, and fixtures before the final finishes of a building or room are completed. It involves laying out and installing the necessary water supply lines, drainage pipes, and vent pipes that will connect to fixtures such as sinks, toilets, showers, and bathtubs. During the rough-in phase, the plumbing system is put in place, tested for leaks, and adjusted if needed. Once the rough-in is complete, the walls and floors are finished, and the final fixtures can be installed.


Plumbing Rough-Ins Considerations Toronto

Things to Prepare Before Plumbing Rough-Ins Process

​Plumbing rough-ins are a complex process that requires a lot of planning and experience. Here is a couple of things to consider before starting the plumbing rough-ins project in Toronto, GTA, or South Ontario:

  • NOT a DIY Project – plumbing rough-ins can make or break the plumbing system in your home and are definitely not something you can do yourself, we recommend talking to licensed plumbers.

  • The Size of Plumbing Rough-Ins - will vary by location, because of different standards, building codes, and other requirements.

  • Plan in Advance - plumbing rough-ins need to account for specific fixtures that are planned. For example, a dishwasher has a different water line size than a fridge or a faucet. Size and requirements for the water lines may change depending on the fixture, water flow, etc.

  • Measure the Space – many plumbing fixtures such as toilets and sinks have space requirements. For example, a toilet needs to be located a certain distance away from the wall, etc. When planning plumbing rough-ins, you need to account for these requirements.

What Is Included Under Plumbing Rough Ins in Toronto?

Sample Plumbing Rough-Ins Process

Plumbing rough-in involves preparing all elements required for the future use of a bathroom - pipes, drains, vents, and other elements will be installed. While specifics of plumbing rough-ins may vary by region and specific requirements, here is a couple of the most talked-about elements of the plumbing rough-in the process:


  • Rough-Ins for Water Supply Lines - these are the pipes that bring clean water into the building or room. They are usually made of copper, PEX, or PVC and are installed with valves to control the flow of water.

  • Drain Pipe Rough-Ins – a part of the drain-wate-vent (DWV) systems. Responsible for carrying wastewater and sewage away from the building. They are typically made of PVC or ABS and are installed at the proper slope to ensure efficient drainage.

  • Vent Pipe Rough-Ins - allow air to enter the plumbing system, preventing vacuum or pressure buildup and enabling proper drainage. Vent pipes are usually made of PVC or cast iron and are connected to drain pipes.

  • Rough-in Fixtures – typically cover the installation of various plumbing fixtures at their intended locations. This may involve setting up the rough-in for sinks, toilets, showers, bathtubs, or other fixtures.

  • Shut-Off Valve Installation - valves are installed at suitable points to control the water supply to different areas or fixtures. This allows for individual shut-off in case of repairs or maintenance.

  • Access Panels - these are openings in walls or ceilings that provide easy access to plumbing components for future maintenance or repairs. Access panels are typically installed

  • Water and Drain Testing - after the pipes are installed, tests are conducted to check if there are any leaks and if everything is draining correctly.

  • Inspection and Approval – a rough-in inspection is required. The city’s inspector checks to make sure the work is up to code. If it’s approved, then insulation and drywall can be installed.


Please note, plumbing rough in installation is NOT a DIY process. It is a complex procedure that requires professional work to ensure the proper functioning of the plumbing system.

  • How long does basement underpinning take?
    The duration of a basement underpinning project can vary depending on various factors, including the size of the basement, the complexity of the existing foundation, and the specific underpinning technique used. Typically, basement underpinning projects can take several weeks to a few months to complete. The process involves a series of steps, including excavation, installation of temporary supports, underpinning the foundation, pouring new concrete footings, and allowing sufficient time for the concrete to cure. The timeline may also be influenced by factors such as weather conditions and any unforeseen challenges encountered during the construction process. It's important to consult with a professional contractor or structural engineer who can assess your specific situation and provide a more accurate estimate of the timeframe required for your basement underpinning project. They will consider the scope of work, project complexities, and any potential disruptions to your daily routine during the construction phase.

  • Common Foundation Problems?
    There is a number of foundation problems that may occur for different reasons. If you notice the or other foundation problems, make sure to talk to an expert as soon as possible as foundation problems tend to get worse over time. Here is a couple of foundation problems that we often see: Cracks in the foundation - cracks can occur due to settling, shifting soil, or poor construction. They can range from minor hairline cracks to larger, more serious cracks that affect the structural integrity of the foundation. Uneven or sinking foundation - may be caused by soil movement or inadequate soil compaction during construction and other problems. It can lead to uneven floors, gaps between walls and floors, or doors and windows that stick. Foundation heaving - heaving may be caused by the soil beneath the foundation expanding, which causes the foundation to rise. This can be caused by excessive moisture, frost, or poor drainage around the foundation. Basement leaks - water seepage or leaks in the basement can be a sign of foundation problems. They can occur due to cracks in the foundation, poor waterproofing, or improper drainage around the foundation. Bowing or leaning walls - when the foundation walls start to bow or lean inward, it is often a result of hydrostatic pressure from water-saturated soil pushing against the foundation. This can lead to structural instability and should be addressed promptly. Settling or sinking foundation - if the foundation settles or sinks unevenly, it can cause cracks in the walls, uneven floors, and misaligned doors and windows. This can be caused by soil consolidation, poor soil compaction, or inadequate foundation design. Foundation deterioration - over time, foundations can deteriorate due to age, exposure to moisture, or poor construction materials. This can lead to weakened foundation walls, crumbling concrete, or loss of structural integrity. The list goes on. Remember, these and other foundation issue should never be ignored. If you see any signs of foundation problems, talk to an expert as soon as possible!
