Signs You Need Urinal Installation
- A commercial washroom is being renovated or expanded with additional fixtures
- An existing urinal is being replaced due to age or damage
- You're fitting out a new washroom in a restaurant, office, or retail space
- A urinal's flush valve or wall mounting needs full fixture replacement
- You're adding a urinal to a basement washroom during a renovation
- Local code or accessibility upgrades require reconfiguring existing fixtures
Planning for commercial washrooms
Commercial urinal installations start with confirming wall structure, since wall-hung units need solid blocking behind drywall to support the weight and prevent movement over years of use. We also confirm the washroom layout meets required clearances between fixtures, which matters more in commercial spaces subject to accessibility and code review than in a typical home.
For any commercial washroom reconfiguration in North York, some plumbing changes require permits and inspection, so we recommend confirming scope with the City of Toronto early in the planning stage, particularly when fixture counts or drain layouts are changing.
Rough-in, venting, and drain sizing
Urinals drain through a smaller trap than a toilet but still need proper venting to avoid trap siphoning and odour issues. We confirm the vent stack serving the washroom can accommodate an added fixture, especially in older commercial buildings where drain and vent runs were sized for fewer fixtures than are being installed now.
Cast-iron drain lines are common in older commercial buildings around North York, and tying a new urinal branch into cast iron requires proper transition fittings to ABS or PVC where used, along with correct slope back to the main stack.
Mounting and installation
Wall-hung urinals are secured to a carrier or blocking at a height appropriate for the space, with the water supply line and flush valve connected and tested for consistent flow. We check that the trap seals properly and that wastewater clears the fixture without pooling.
For manual flush valves we test the flush volume and timing, and for sensor-operated units we confirm power supply, typically battery or low-voltage, is properly installed and the sensor is calibrated to activate reliably.
Commercial washroom notes
Multi-fixture washrooms often mean staggering water shutoffs so the rest of the building's plumbing keeps functioning during installation, which matters for businesses that can't close entirely for the work. We plan the sequence with the property manager or contractor overseeing the space so occupied units or offices nearby aren't disrupted longer than necessary.
Privacy partitions between urinals are typically installed by a general contractor rather than a plumber, but we coordinate the fixture spacing with that trade so partition placement doesn't conflict with supply or drain connections behind the wall.
Water efficiency is a common question in commercial fit-outs. Ultra-low-flow and waterless urinal models each have different maintenance and trap requirements, so we discuss what the manufacturer specifies for cleaning and servicing before recommending one for a high-traffic washroom.
Planning the rough-in
Getting the rough-in height and spacing right the first time matters more in commercial settings, where multiple identical fixtures need to line up evenly along a wall for both appearance and code-driven clearance requirements. We measure carefully against the carrier or blocking before any drain branch is cut in.
When several urinals are being added along the same wall, we plan the branch drain layout so each fixture ties into the main line at a workable slope without conflicting with the others, which takes more coordination than a single residential fixture install.
How We Handle It
- 1
Site assessment
We review the washroom layout, wall structure, and existing drain and vent capacity.
- 2
Confirm permit scope
For new fixture additions we flag whether the work should be confirmed with the City before proceeding.
- 3
Rough-in drain and vent
Branch drain and vent lines are run or tied into the existing stack with correct slope.
- 4
Mount and connect fixture
The urinal is secured to blocking or a carrier, then connected to supply and drain.
- 5
Test flush and seal
We test flush volume, check the trap seal, and confirm there's no leaking at any joint.

Read our reviews on GoogleFrequently Asked Questions
Do urinal installations require a permit?
It depends on scope. Adding a new fixture or changing drain layout can require permits and inspection, so we recommend confirming with the City of Toronto before work begins.
Can a urinal be installed on any wall?
The wall needs solid blocking to support a wall-hung urinal, which we check before installation and can add if the existing wall isn't suitable.
Do you install urinals in residential basements?
Yes, though it's less common than commercial work, and we make sure drain and vent sizing in the basement can properly support the added fixture.
What's the difference between manual and sensor flush valves?
Manual valves are mechanically operated by hand, while sensor valves use a low-voltage or battery-powered sensor to trigger the flush, and we can install or service either type.
Can an existing urinal be swapped for a new one without changing the plumbing?
If the new urinal matches the existing rough-in and drain connection, replacement is usually straightforward without altering the underlying plumbing.
