Commercial Washrooms Are More Complicated Than They Look
A commercial washroom renovation is rarely as straightforward as it appears on paper. You’re dealing with plumbing rough-in that may not match current fixture layouts, Ontario Building Code requirements for accessible stall configurations, ventilation systems that need to be upgraded alongside the finish work, and tile and waterproofing details that have to be done the first time correctly — because failures behind the wall don’t show up until they’ve already caused damage.
Silcon Construction renovates commercial washrooms across the GTA for a wide range of clients: office buildings, retail tenants, restaurants, industrial facilities, and property managers overseeing multi-tenant properties. We coordinate the plumbing, electrical, mechanical, tile, and finish trades as a single managed scope. So the project runs in the right sequence, the inspections pass, and the finished washroom performs as a high-use commercial space needs to.
Whether you’re bringing an aging washroom up to current accessibility standards, refreshing a dated finish package, or building new washroom facilities inside a renovated space, we execute the scope with the same rigour we bring to every commercial project we take on.
What Commercial Washroom Clients Tell Us Before They Call
Ontario’s accessibility legislation and the Ontario Building Code set specific requirements for accessible washroom design — turning radii, grab bar placement, counter heights, door hardware, and stall dimensions. Non-compliance isn’t just a liability risk; it also arises during building inspections, lease renewals, and tenant complaints. We assess existing conditions, identify the gaps, and execute the retrofit to bring the space into compliance.
Commercial washroom failures are almost always a waterproofing failure in disguise — grout joints that weren’t properly sealed, shower bases that weren’t sloped correctly, membrane applications that missed a seam. We waterproof correctly before the tile goes down, so you’re not pulling out a finished washroom two years after opening to find water damage in the substrate.
For property managers overseeing multi-tenant commercial buildings, aging washrooms are a recurring source of tenant complaints, maintenance calls, and capital expenditure surprises. A properly renovated washroom — with durable finishes, correctly installed fixtures, and properly sloped drains — significantly reduces the ongoing maintenance burden. We approach multi-unit washroom upgrades as planned capital projects, not reactive repairs.
Commercial washroom renovations in occupied buildings require careful planning around building access, water shutoff windows, and the availability of alternative facilities for building occupants. We schedule work to minimize impact, coordinate shutoffs with building management, and sequence the scope to return the space to service as quickly as possible.
Commercial Washroom Renovation Services We Deliver
Full Washroom Demolition & Rebuild:
Complete gut-and-rebuild of existing commercial washrooms — demolition of existing tile, fixtures, partitions, and plumbing rough-in, followed by a full rebuild to current Ontario Building Code standards. We manage every trade from demolition through to final fixture installation and touch-up.
Accessibility Retrofits & AODA Compliance:
Reconfiguration of existing washroom layouts to meet Ontario Building Code accessibility requirements — widening stall openings, installing grab bars to CSA B651 specifications, adjusting counter and mirror heights, replacing door hardware with lever-style openers, and modifying turning radii to accommodate mobility devices. We assess the existing layout, identify every gap, and execute the retrofit as a coordinated scope rather than a checklist of isolated fixes.
Plumbing Rough-In & Fixture Replacement:
New plumbing rough-in for repositioned or added fixtures, replacement of aging supply and drain lines, installation of water-efficient toilets, urinals, sinks, and touchless faucet systems. We coordinate licensed plumbing subcontractors as part of the managed scope and ensure that all rough-in is inspected and approved before walls close and tile is installed.
Waterproofing & Tile Installation:
Proper membrane waterproofing beneath tile surfaces in wet areas — shower bases, floor areas, and walls adjacent to fixtures. Large-format porcelain, ceramic, and natural stone tile installation with correctly sloped floors, properly grouted joints, and finished transitions. We do the waterproofing correctly the first time, so the tile work isn’t masking a future leak.
Washroom Partition Systems:
New toilet partition systems in powder-coated steel, stainless steel, solid plastic, or phenolic resin — selected for the appropriate level of durability based on the facility type and daily traffic volume. We supply, deliver, and install partition systems as part of the overall scope.
Ventilation & Exhaust Upgrades:
Replacement or upgrade of washroom exhaust fans to meet current OBC ventilation rate requirements, including new ductwork runs where existing routing is inadequate. Properly ventilated commercial washrooms prevent moisture accumulation, mould growth, and odour issues — we treat ventilation as a functional requirement, not an afterthought.
Ceiling & Lighting
Upgrades:
Moisture-resistant drywall ceilings, suspended grid ceilings, and specialty ceiling systems appropriate for commercial washroom environments. LED lighting upgrades, including vandal-resistant and moisture-rated fixtures appropriate for the occupancy type. Lighting is coordinated with the electrical trade as part of the overall project scope.
Multi-Stall & High-Traffic Washroom Builds:
Large-scale washroom construction for high-occupancy commercial facilities — shopping centres, event venues, large office floors, and industrial facilities with significant workforce populations. We size fixture counts to occupancy load, plan the layout for efficient traffic flow, specify finishes durable enough for thousands of daily uses, and manage the construction as a coordinated multi-trade project.
Phased Washroom Upgrades for Occupied Buildings:
For property managers and building owners who need to renovate multiple washrooms in an occupied building without taking them all offline at once, we plan and execute phased renovation programs — one washroom at a time, sequenced to keep alternative facilities available to building occupants throughout the program.
Why Commercial Building Owners and Tenants
Choose Silcon for Washroom Renovations
Commercial washroom renovations in Ontario touch multiple code regimes — the Ontario Building Code, the Accessibility for Ontarians with Disabilities Act, and local municipality requirements. We don’t treat compliance as a final checklist item; we design the scope around the requirements from day one. Our projects pass inspections the first time because the work is done correctly, not because we scramble to fix deficiencies after the inspector leaves.
Most commercial washroom failures — leaks, cracked tile, moisture damage behind walls — trace back to one trade working without awareness of what the next trade needed. Waterproofing was applied before the plumber finished. The tile was installed before the membrane was fully cured. Accessories are mounted without blocking. We sequence the trades correctly and hold each one accountable to the standard required by the next phase. The washroom you get at the end performs the way it should because every phase was done in the right order.
We understand that taking a commercial washroom out of service in an occupied building has a real impact on the people using the facility. We plan shutdown windows with building management, accelerate the construction sequence where possible, and communicate the timeline to everyone affected. You get a dedicated site supervisor managing the job daily and reporting progress to you — not a crew that disappears and resurfaces when they’re finished.
Commercial Washroom Upgrades Across Every Property Type
Commercial washroom renovation needs vary significantly by property type. Here’s how we approach each:
Office Buildings & Multi-Tenant Properties
Washroom upgrades in occupied office buildings require careful coordination with building management and tenant communication. We work within building access windows, minimize water shutoff durations, and phase the work to keep the building functional throughout the project. For property managers overseeing multiple floors or units, we plan the program as a capital project with a phased schedule that fits the building’s operational calendar.
Retail & Mall Environments
Retail washrooms — particularly in enclosed malls and high-traffic plazas — take a significant amount of daily punishment. Finish selections have to be durable, vandal-resistant, and easy to clean. We specify and install materials appropriate for high-traffic retail environments and coordinate the work within property management’s approved construction windows.
Restaurants & Food Service Facilities
Restaurant washrooms are subject to Toronto Public Health inspection standards as well as Ontario Building Code requirements. Finish materials, fixture types, and ventilation requirements are all influenced by the food service occupancy designation. We build to those standards from the start so your washrooms pass health inspection alongside the rest of the facility.
Industrial & Warehouse Facilities
Industrial washrooms serve a different functional purpose than office or retail washrooms — they need to handle heavy use by a large workforce, tolerate the conditions of an industrial environment, and meet occupancy-based fixture count requirements. We build and retrofit industrial washrooms with the durability and functionality that working facilities require.

Approval & Mobilization
Once the quote is approved, we coordinate permit submissions, order materials, schedule trades, and align the construction window with your building management team. Shutoff windows and alternative facility arrangements are confirmed before we mobilize — not figured out on day one.
Managed Execution Through to Final Inspection
A dedicated site supervisor manages the scope daily, sequences trades correctly, and ensures each phase is completed to standard before the next begins. We coordinate building inspections, manage deficiency corrections promptly, and hand over a washroom that is clean, fully functional, and ready for use — not a punch list you’re still chasing three weeks after the crew left.
