How the count is set
The Alberta Building Code and plumbing requirements specify minimum fixtures by use, such as offices, restaurants, retail and assembly. The number of occupants and the split between genders or universal washrooms affect the total.
Your designer calculates this at the start, since it drives floor area.
Mixed-use spaces, such as a cafe with a seating area and a retail corner, are checked against more than one category.
Existing buildings
A leased space may share washrooms with other tenants, or the existing group may not meet the new use. Adding fixtures involves new drains, vents and water lines, and slab cutting.
Our plumbers check the location of existing stacks and the slab before the layout is fixed.
Drain slope limits how far fixtures can sit from a stack, which sometimes dictates the entire layout.
Layout efficiency
Grouping wet rooms back-to-back and close to existing stacks minimizes piping and cost. Placing kitchens, washrooms and break rooms together makes sense for the same reason.
Accessible and universal washrooms need extra space, so plan them early.
Fixtures and finishes
Choose durable, water-efficient fixtures that are easy to clean and repair. Touchless faucets and flush valves suit high-traffic areas but need power or batteries, which our electricians can provide.
Partitions, tile and accessories are coordinated with our interior systems crew.
Backflow and other requirements
Some fixtures need backflow protection, floor drains or hot water recirculation. Inspections check these items, so they must be correct before walls close.
Cleaning and supply storage should be considered as well. A janitor's closet with a mop sink is often required and easily forgotten.
Questions we hear
Can we share washrooms with other tenants?
Sometimes, if the lease and code allow. Confirm the count before signing.
Are universal washrooms allowed?
Often yes. Confirm with your designer what the current code permits.
