A bathroom renovation in Richmond Hill works best when the hidden parts are planned before the finishes. A 1960s main bath in Richvale or near Mill Pond, a 1990s ensuite in Bayview Hill or Rouge Woods, and a newer builder bathroom in Jefferson or Oak Ridges each have different plumbing, venting, and layout limits. This guide walks Richmond Hill homeowners through what to decide first, when a permit is needed, how to waterproof and ventilate properly, and the right order of work, based on about 20 years of hands-on construction and roughly 15 years as a home inspector in Ontario.
Key Takeaways
- Keeping fixtures where they are is the simplest path. Moving drains, stacks, or walls adds time and often a permit.
- Adding a bathroom or changing drains, vents, or structure generally needs a City of Richmond Hill building permit.
- New or changed electrical work needs an ESA permit and a Licensed Electrical Contractor.
- A continuous shower waterproofing membrane and an exhaust fan ducted outdoors matter more than the tile.
- Older homes often hide water damage, so plan for repairs once the walls are open.
What should you decide first for a Richmond Hill bathroom renovation?
Begin with how the bathroom is used and what is not working today. A shared family bath may need a tub and plenty of storage. A primary ensuite might swap a rarely used soaker tub for a larger walk-in shower with a bench. Make a short list of real problems: a fan that does not clear steam, cracked tile at the tub, a soft floor near the toilet, poor lighting, or a leak that stained the ceiling below. That list should drive the scope.
Then decide whether the toilet, tub or shower, and vanity stay in their current spots. In most Richmond Hill homes the stack location sets the layout. Small moves on a wood floor are sometimes possible; moves on a concrete basement slab mean cutting the floor. We confirm what is realistic on a site visit before any design is locked in.
How do older and newer Richmond Hill homes differ?
| Home type | Typical areas | Common issues | What we check first |
|---|---|---|---|
| 1950s to 1970s homes | Richvale, Crosby, around Mill Pond and the old village core | Older supply and drain materials, tile over plaster, little or no exhaust venting | Pipe materials, subfloor condition, electrical capacity |
| 1980s and 1990s homes | Bayview Hill, Rouge Woods, Devonsleigh, Westbrook | Large tubs with little use, tired tub surrounds, undersized fans, poly-b supply in some homes | Water damage behind tub walls, pipe type, fan ducting |
| 2000s and newer builds | Jefferson, Oak Ridges, Elgin Mills area, newer infill | Builder-grade fixtures, tight layouts, fan ducts that end in the attic or come apart | Fan termination, shower membrane, layout limits |
| Basement bathrooms | Across Richmond Hill | Missing rough-in, low ceilings, need for an ejector pump | Rough-in location, drain slope, permit path |
Do you need a permit for a bathroom renovation in Richmond Hill?
It depends on the scope. Replacing a vanity, toilet, or tub in the same location, with no changes to drains, vents, or structure, usually does not need a building permit. Adding a new bathroom, adding or relocating drains and vents, or removing or altering load-bearing walls generally needs a building permit from the City of Richmond Hill, with plumbing inspections during the job.
Electrical work is regulated separately by the Electrical Safety Authority (ESA). New circuits, added pot lights, heated floors, and moved receptacles should be done by a Licensed Electrical Contractor who files the ESA permit and arranges the inspection. Receptacles near tubs and showers need ground fault (GFCI) protection under the Ontario Electrical Safety Code. Rules are updated from time to time, so confirm your exact scope with the City of Richmond Hill building department before you start.
How do you waterproof and ventilate a bathroom properly?
Tile and grout are not waterproof on their own. We install a continuous waterproofing membrane on shower walls and floors, sloped correctly to the drain, and carry it through niches, benches, and curbs, since those corners are where most leaks begin. For curbless showers we plan the floor recess or slope before framing so water stays where it belongs.
Ventilation is just as important. The Ontario Building Code requires mechanical exhaust in bathrooms, and the fan should be ducted to the exterior, not left blowing into the attic. In many Richmond Hill homes we find ducts that are crushed, disconnected, or never reached the outside, which leads to frost, staining, and mould in winter. New showers also need a pressure-balanced or thermostatic mixing valve to limit scalding.
Because Nehan Construction also does home inspections, we assess the bathroom the way an inspector would: moisture readings around the tub, soft spots at the toilet, staining on the ceiling below, and how well the fan actually moves air.
What is the right order of work?
- Site visit, measurements, and a written scope.
- Permits, if the scope needs them, and product selections.
- Demolition and inspection of the open walls and floor.
- Repairs to subfloor, framing, and any water damage found.
- Plumbing and electrical rough-in by licensed trades, with inspections.
- Fan ducting, insulation on exterior walls, and backer board.
- Waterproofing membrane and a flood test of the shower pan.
- Tile, then vanity, toilet, fixtures, glass, paint, and final inspections.
Richmond Hill Bathroom Renovation Checklist
- List the problems you want solved, not only the look you want.
- Decide whether fixtures stay in place or move.
- Confirm the permit path with the City of Richmond Hill for drain, structural, or new bathroom work.
- Use a Licensed Electrical Contractor with an ESA permit for electrical changes.
- Plan a continuous shower waterproofing membrane.
- Confirm the exhaust fan is ducted outdoors and sized for the room.
- Choose a pressure-balanced or thermostatic shower valve.
- Order tile, vanity, and fixtures early to avoid delays.
- Keep a contingency for what is found behind the walls.
Why hire a licensed contractor for your Richmond Hill bathroom?
A bathroom packs water, electricity, ventilation, and code requirements into a small room, so small shortcuts show up quickly as leaks or mould. Nehan Construction is led by a licensed contractor with about 20 years of hands-on construction experience, construction engineering training from George Brown College (Building Renovations), and roughly 15 years of home inspection experience, among the top inspectors in Ontario. We are fully insured with WSIB coverage, work with licensed plumbing, electrical, and HVAC subcontractors, and build to the Ontario Building Code. Low overhead helps keep pricing fair.

Frequently Asked Questions
Do I need a permit to renovate a bathroom in Richmond Hill?
Not for like-for-like fixture replacement. Adding a bathroom, moving drains or vents, or structural changes generally need a City of Richmond Hill building permit. Electrical changes need an ESA permit.
Can I replace my tub with a walk-in shower?
Usually, yes. The drain often needs to move or be resized, and the new shower needs a proper waterproofing membrane and a pressure-balanced or thermostatic valve. We confirm the details on site.
How long does a bathroom renovation take?
A bathroom with fixtures staying in place often takes a few weeks of on-site work. Moving plumbing, permits, inspections, and special-order products add time. We give a realistic schedule after the site visit.
Does my bathroom fan need to vent outside?
Yes. The exhaust fan should be ducted to the exterior. Venting into the attic causes moisture, frost, and staining.
