Bathroom Renovations in Kingston's Older Homes

Small bathrooms are the norm in older Kingston homes

The bathrooms in Kingston's older homes were not built for the way we live now. A typical Sydenham Ward bathroom is a 5-by-8-foot galley - tub along one wall, vanity across from it, toilet squeezed in at the end. The "master bath" in many of these homes is really just the main bathroom, and there is often only one.

Renovating that kind of space well is a design problem before it is a carpentry problem. Every inch matters. A walk-in shower instead of a tub can open up the whole room, but the pan has to fit the existing drain location or the cost climbs fast. A floating vanity gives back visual space and floor area, but the wall behind it has to be solid enough to hold it. Recessed niches in the shower replace shelving that would eat into the footprint.

We have done enough of these small Kingston bathrooms that we know which layouts work and which fight the space. The goal is a bathroom that feels bigger and works better - not one that just has new tile on the same cramped layout.

What is behind the walls

When you open up a 100-year-old bathroom, you usually find a combination of three things, and they all matter:

Galvanized and old supply lines

Many pre-1960 Kingston homes still have galvanized steel water lines. They narrow over decades as minerals build up inside, so the shower pressure is disappointing and the pipes are near the end of their life. A bathroom reno is the right time to replace them with PEX or copper.

Cast iron waste stacks

The original cast iron drain can be perfectly fine or quietly failing. We assess it when the walls are open and replace the sections that need it. This is also the moment to think about venting - old bathrooms were often under-vented, which is why the toilet gurgles when someone runs a sink.

Knob-and-tube wiring

If your home still has knob-and-tube wiring in the bathroom walls, it needs to go. It is not rated for the loads a modern bathroom pulls - exhaust fan, heated floor, lighting, a GFCI outlet by the vanity - and most insurers want it replaced. We coordinate a licensed electrician to bring the circuit up to code while the walls are open.

None of this is a reason not to renovate. It is the reason to renovate with the walls open, so these things get fixed once, properly, instead of being buried behind brand-new tile.

Limestone exterior walls and thick plaster

In an older Kingston home, the exterior wall of the bathroom is often solid limestone - sometimes 18 inches thick or more. That changes a few things. There is no hollow stud cavity to run wiring or a new exhaust duct through, so we have to plan the routing carefully, sometimes furring out the wall to create space for mechanicals.

The interior walls are usually original wood lath and plaster, which is beautiful but fragile. When we open a wall we preserve as much of the original character as we can, and we match the plaster repair so the renovation does not look like a modern box dropped into an old home.

Venting a bathroom fan through a thick limestone wall is one of those details that separates a contractor who has worked here from one who has not. It is doable - we do it all the time - but it has to be planned, not improvised at the end of the job.

Kingston bathroom permits - handled for you

In Kingston, a bathroom renovation needs a building permit when you move plumbing, change electrical wiring, or make structural changes - which, in an older home, is most renovations. Surface updates like swapping a vanity, retiling, or changing a toilet usually do not need a permit, but they still have to meet code.

The permit process with the City of Kingston means drawings, a description of the plumbing and electrical work, and a review by the building department before construction, then inspections at the right stages. For a homeowner, that is a lot of unfamiliar paperwork and a few trips to City Hall - and a rejected submission can stall a project for weeks.

Here is the value of having us do it. We have pulled bathroom permits with the City of Kingston for over 20 years. We know exactly what their reviewers want to see, so we submit complete, code-compliant drawings the first time. We are your point of contact with the city and the inspector, so you never have to interpret the building code or chase anyone down. And because the work is permitted and inspected, your renovated bathroom is properly documented - which matters for insurance and for resale.

• You do not go to City Hall. We submit the drawings and the application.
• You do not get rejection letters. Complete, code-compliant submissions mean a smooth review.
• You do not meet the inspector alone. We schedule and sit in on every required inspection.
• Your renovation is legal and documented. Clean permits protect you when you sell.

A surprising number of bathroom renovations in older Kingston homes were done without permits by someone who is no longer around. When those homes go up for sale, the missing permits become the seller's problem. We make sure that is never you.

Heritage considerations in Kingston

Some parts of Kingston - the Sydenham Ward heritage conservation district, for example - have additional rules on top of the standard building permit. If your home is heritage-designated, certain exterior changes and sometimes interior changes require heritage approval as well.

We are familiar with navigating those requirements. Most bathroom renovations in heritage homes are interior work and go through smoothly, but if your project touches a heritage element we make sure the approvals are in place before any demolition. The last thing you want is to find out mid-project that a heritage review was required.

What an older-home bathroom renovation costs

A full bathroom renovation in Kingston runs roughly $15,000 to $30,000, with luxury primary bathrooms going higher. Older homes tend to land in the middle-to-high end of that range because of the plumbing, electrical, and ventilation work we uncover behind the walls.

We always tell homeowners to expect - and budget for - the discovery behind the walls. It is not a surprise in a 100-year-old home; it is the norm. We flag it up front and keep you informed as we go, so there are no shocks halfway through.

We hand you an itemized quote before we start, and we explain every line. No vague estimates that grow later.
