A bathroom plumbing system needs to do more than move water in and waste out. It needs to work safely, drain properly, prevent sewer gases, and meet local building codes. Whether you are planning a renovation, replacing old fixtures, or dealing with leaks underneath a sink, every part of the system needs to be installed correctly.
Lister Plumbing provides bathroom plumbing in Ottawa for homeowners who need dependable work completed to code. From bathroom sink plumbing and toilet drain repairs to shower installations, vent issues, and full rough-ins, we handle every stage of the job with care. Our professional plumbers understand the key components of a bathroom plumbing system and make sure each one works together properly.
We begin by reviewing the bathroom plumbing issue, renovation plan, or installation needs. This helps us understand the system, the fixtures involved, and the best next step.
We inspect the bathroom plumbing system, including supply lines, drainage pipes, vent pipes, sink drain connections, and any visible leaks or signs of pressure issues.
We prepare a clear quote and explain the scope of work. For renovation projects, we review rough in dimensions, plumbing code requirements, and access behind the wall or underneath the floor.
Our team completes the plumbing installation or repairs, including drain pipe work, toilet connections, bathroom sink plumbing, shower or bathtub lines, and any needed vent or waste updates.
We test flow, drainage, hot water, cold water, and pressure to ensure the system performs properly. We also check that all components are sealed and functioning as they should.
Real feedback from our valued customers based on their genuine experience with Lister Plumbing.
A bathroom plumbing system has two distinct subsystems working together. One system brings in clean water through the water supply lines. The other removes waste and wastewater through the drainage system. These distinct subsystems must both function properly for the bathroom to work safely and efficiently.
Supply lines bring hot water and cold water to fixtures like the bathroom sink, shower, bathtub, and toilet. Waste lines then carry used water away through the drain pipe network. Gravity pulls waste through the drainage pipes, which is why proper slope is so important. Without that slope, water can sit in the pipes, slow down drainage, and create future problems.
Vent pipes are also a vital part of the system. They allow air into the plumbing system so water can drain smoothly and pressure stays balanced. A working vent stack also helps prevent sewer gas from entering the bathroom.
Bathroom sink plumbing may look simple from the outside, but several components must connect correctly for the system to work. A bathroom sink typically includes the faucet, sink tailpiece, sink drain, P-trap, trap adapter, slip joints, and supply lines.
The P-trap is especially important because it holds water and creates a seal that prevents sewer gases from rising back through the drain. A properly installed P-trap kit, along with secure slip joints and a watertight seal, helps prevent leaks and protects the drainage system. If the sink drain is slow, smells bad, or leaks underneath, the issue may be tied to the trap, the sink tailpiece, the drain hole connection, or worn washers.
When installing a new sink, we make sure the sink plumbing is aligned properly, all components connect correctly, and both the hot water and cold water supply are working as they should.
During a bathroom renovation, plumbing needs to be planned before the finished floor and wall surfaces are complete. Rough in dimensions are critical because they determine where the toilet, sink, shower, and bathtub will sit once the bathroom is finished. These measurements must line up with the final design and comply with local building codes.
When plumbing is installed behind an unfinished wall, we ensure the water supply, drain, waste, and vent locations are correct from the start. This reduces the risk of costly changes later in the renovation process. Proper rough-in work also makes future repairs easier by improving access and ensuring the bathroom plumbing system is built correctly from day one.
Bathroom plumbing issues can show up in different ways. Some of the most common include:
Leaks underneath the sink
Slow drainage from the sink or shower
Sewer gas smells in the bathroom
Loose or leaking slip joints
A blocked toilet drain
Poor venting that affects flow
Drainage pipes with the wrong slope
Old pipes that need replacement during renovation
These problems can affect comfort, code compliance, and long-term reliability. Our goal is to identify the cause, complete the right repairs, and help prevent future repairs wherever possible.

What causes sewer gases in a bathroom?
