Dunnville homes
What bathroom renovations involves in Dunnville's houses
Century and heritage homes in Dunnville
Bathrooms in Dunnville's older homes were often fitted into a former bedroom or closet, with cast-iron drains, galvanized supply lines and floors that have sagged around the toilet. We open the floor to check the joists, replace old piping while it is exposed, and add proper ventilation, which many older bathrooms never had.
Rural homes on well and septic in Dunnville
Adding or enlarging a bathroom on a rural Dunnville property can affect the septic system, especially when it comes with an extra bedroom. We check the system before planning and, where it needs review or a permit, include that in the scope. Hard well water is also worth planning for with the right fixtures and filtration.
Lakefront and riverside properties in Dunnville
Lakeside and riverside homes around Dunnville are prone to humidity, so ventilation matters even more than usual. We size the exhaust fan for the room, vent it outside, and use a continuous waterproofing membrane behind every tiled wet area.
Rules in Dunnville
Permits and approvals for bathroom renovations in Dunnville
Building permits
Building permits in Dunnville are issued by the Haldimand County. Electrical work anywhere in Ontario is done by a licensed electrical contractor under an Electrical Safety Authority (ESA) permit. We confirm what your project needs before you sign and book every inspection.
Conservation authority
Much of Dunnville falls within the Grand River Conservation Authority (GRCA) watershed. Building near a shoreline, river, floodplain, valley or wetland can need a conservation authority permit before the municipality will issue a building permit. We check the regulation mapping for your property early so it does not hold up the schedule.
Septic and well
On Dunnville-area properties with a private septic system, adding bedrooms, bathrooms or a second unit can increase the design flow beyond what the system was built for. Septic changes need a sewage system permit under Part 8 of the Building Code, issued by the municipality or the agency it designates. We assess the system first so there are no surprises at permit stage.
Testing before demolition
Homes built before the 1990s can contain asbestos in plaster, textured ceilings, floor tile, vermiculite insulation and pipe wrap, and homes from before the 1960s often have lead paint. In Dunnville's older houses we test suspect materials before demolition and handle them by the regulations if they are found.
The service
Bathroom Renovations Built to Stay Dry
A bathroom is the hardest-working room in the house for its size. Water, steam and daily use find every weak point, so a good bathroom renovation is mostly about what goes behind the tile: a properly sloped shower base, a continuous waterproofing membrane, correctly sized ventilation and plumbing that is done right the first time.
We renovate main bathrooms, ensuites, powder rooms and basement bathrooms, from full gut remodels to tub-to-shower conversions. Popular upgrades include glass walk-in showers with a linear drain, floating vanities, heated floors, niches and larger-format tile.

Questions
Bathroom Renovations in Dunnville: FAQs
How do I get a bathroom renovations quote in Dunnville?+
Call (647) 424-1511, use the form on this page or email info@ontariorenovationcompany.com. Tell us what you want to change and send a few photos, and we will book a visit and send a written quote for your Dunnville project.
What kinds of Dunnville homes do you work on?+
All of them. Housing in Dunnville includes century and heritage homes, rural homes on well and septic and lakefront and riverside properties, and each comes with its own considerations, from older wiring and foundations to builder warranties, septic systems and shoreline rules. We plan the work around the house you actually have.
Do I need a conservation authority permit in Dunnville?+
Only if your property is in a regulated area, such as near a shoreline, river, valley, floodplain or wetland. Much of Dunnville falls within the Grand River Conservation Authority (GRCA) watershed. We check the mapping for your address before applying for the building permit.
My Dunnville-area home is on septic. Can I still do this project?+
Usually, yes, but the septic system has to be able to handle the added bedrooms, bathrooms or unit. We assess the system first, and if it needs an upgrade, the sewage system permit and the work are planned into the project.
How long does a bathroom renovation take?+
A straightforward bathroom remodel usually takes a few weeks of on-site work, longer if plumbing is moving, the subfloor needs repair or custom glass is ordered. Your quote includes the schedule.
Can you convert my bathtub into a walk-in shower?+
Yes. Tub-to-shower conversions are one of the most common bathroom projects we do. The drain, shower base and waterproofing are rebuilt for the new layout, and the shower can be curbless if the floor allows it.
What is the most important part of a bathroom renovation?+
Waterproofing. Tile and grout are not waterproof on their own. A continuous membrane behind the tile and under the shower floor, with a properly sloped base, is what keeps water out of the walls.
Do I need a permit to renovate a bathroom?+
Replacing fixtures in the same place usually does not. Adding a new bathroom, moving drains or making structural changes generally does. We confirm the requirements with your municipality.
Do you offer bathroom renovations across Dunnville?+
Yes. We work throughout Dunnville, including Downtown Dunnville, Port Maitland, Byng and Lowbanks, and in nearby Caledonia, Stoney Creek, Hamilton, Ancaster and Dundas.
