Counts, layout and access
The number of fixtures required depends on the use of the building and the number of occupants, under the National Building Code, Alberta Edition. Accessible washrooms have specific size, turning space and fixture requirements. We confirm the needs early since they set the room size.
Layout also affects cost. Stacking washrooms above each other, or backing them onto a shared wall, shortens pipe runs and reduces cost.
What goes into a washroom
- Water supply and drain rough-in
- Floor drains and cleanouts
- Framing, blocking for grab bars and accessories
- Waterproofing and tile or sheet flooring
- Partitions, vanities and countertops
- Exhaust fans and ventilation
- Lighting, receptacles and motion sensors
- Fixtures, faucets and accessories
One crew, one sequence
A washroom job involves many handoffs. Our plumbers rough in, our framers set walls, inspection happens, our drywall and finishing crews close up and our plumbers return to set fixtures. Because everyone works for HSM, the schedule is ours to manage.
Our electricians handle lighting, sensors and exhaust connections at the same time. Our mechanical crew installs the exhaust duct to the roof or wall.
Materials and durability
Washrooms see heavy use. Choose finishes that stand up to cleaning products and moisture. Touchless faucets, flush valves and dryers cut maintenance and improve hygiene, though they depend on power and batteries, so we plan for both.
Water-saving fixtures reduce use, and many are standard now. We can advise on trade-offs, since very low-flow drains in long horizontal runs can need care.
In renovations, we check the existing slab and drain locations before promising a new layout. Moving drains in a slab means cutting and patching concrete, which adds cost and time. Where possible we work with the existing locations. Add a plan for cleaning access and replacement parts, so the finished room stays in good shape.
