Bathroom Renovations in Westboro: Costs for Older Homes (Bathroom Renovation Westboro Guide)
Westboro bathrooms sit inside some of the oldest housing stock Bytown works in: pre-war and 1950s homes, galvanized supply lines, plaster walls and rooms under 50 square feet. This page explains what that does to the price, and what it does not.
The short answer
A bathroom renovation in Westboro starts at the same published bands as anywhere else in Ottawa: $13,000 to $15,000 CAD for a tub-to-shower conversion or bathtub remodel, and from $20,000 CAD for a complete renovation. The honest caveat is that in a pre-war or 1950s Westboro home the quote can change after demolition, because galvanized supply lines, wiring from the knob-and-tube era and uninsulated exterior walls only show themselves once the old tub surround comes off. A full gut with new electrical and insulation is a bigger job than the 1 to 3 day install and is priced as one.
- Pricing: $13,000 to $15,000 CAD tub-to-shower or bathtub remodel, shower from $13,000 CAD, complete renovation from $20,000 CAD, identical across Ottawa
- Older-home surprises: quoted as written change orders after demolition, never absorbed silently
- Timeline: 1 to 3 days on site for tub and shower work in the existing footprint; a gut with rewiring and insulation is scheduled separately
- Warranty: 5 year written warranty on labour and supplied materials
Prices checked against Bytown's pricing page on September 4, 2026 and confirmed in a recorded owner interview on September 2, 2026. What is behind your walls is unknown until demolition, so treat every figure here as a planning band.
What this page covers
What a bathroom renovation costs in Westboro
Bytown Bath does not price by neighbourhood. Confirmed directly with the owner on September 2, 2026: "anywhere within the Ottawa area, it's all going to be the same price." A Westboro address pays the same bands as Kanata, Nepean, Barrhaven or Orleans, and the bands below come from Bytown's own pricing page, which is the canonical source for every number on this page.
| Job type | Published range | Time on site | What an older home can add |
|---|---|---|---|
| Tub-to-shower conversion | $13,000 to $15,000 CAD | 1 to 3 days | Galvanized supply replacement, plaster repair at the surround edge |
| Bathtub remodel | $13,000 to $15,000 CAD | 1 to 3 days | Same as above, plus a drain rebuild if the trap is original |
| Shower remodel or installation | from $13,000 CAD | 1 to 3 days | Framing corrections where walls are out of square |
| Complete bathroom renovation | from $20,000 CAD | quoted per scope | Electrical replacement, new rough-in, insulation and vapour barrier |
What Westboro changes is not the starting price but the odds of a change order. The published band assumes dry walls, copper or PEX supply lines and modern electrical. In a house built before 1960 none of those can be assumed. Every job carries a 5 year written warranty on labour and supplied materials, plus the manufacturer's limited lifetime warranty on most of the acrylic systems Bytown installs.
Which era is your Westboro house from, and what usually needs upgrading?
Westboro is not one kind of house. Two blocks off Richmond Road you pass pre-war brick two-storeys, 1950s bungalows and recent infill on lots where an older house came down. Each is a different bathroom job. Will Culleton's view after opening up plenty of them: older houses have "good bones", and "homes were just built better back in the 50s and 60s". The structure rarely needs work. Everything else does.
| Housing era | Typical bathroom | What usually needs upgrading | Effect on scope |
|---|---|---|---|
| Pre-war (1900s to 1940s) | Under 50 square feet, cast iron tub, plaster and lath walls | Galvanized supply lines, knob-and-tube era wiring, no wall insulation, original drain | Highest chance a tub swap becomes a gut |
| Post-war (1950s to 1960s) | 5 foot alcove tub, plaster or early drywall, tile on mortar bed | Galvanized or early copper supply, 2-wire circuits, thin or missing insulation on exterior walls | Change orders common, structure usually sound |
| 1970s to 1990s updates | Previously renovated room inside an older shell | Depends entirely on what the last renovator left behind the new surface | Unknown until demolition |
| Richmond Road infill and conversions (2010s onward) | Modern footprint, PEX or copper, current electrical | Rarely anything behind the wall | Most likely to run to the 1 to 3 day plan |
The small-footprint question
Many pre-war Westboro bathrooms are under 50 square feet, and small does not mean cheap on a tub or shower job: the fixture, the wall system and the removal labour are roughly the same whether the room is 40 or 80 square feet. Where footprint matters is scope, because a small room limits what can move. Our guide to small bathroom renovation in Ottawa covers layouts that work inside the existing footprint.
What changes the quote after demolition: a real west-end job
The clearest way to explain older-home pricing is a job Bytown actually did, a few kilometres west of Westboro in the Britannia area, off Carling near the hospital. It was quoted as a tub-to-tub replacement, the simplest job on the price table above. Once the old surround came off, the crew found there was no insulation at all in the exterior walls, the electrical serving the room was obsolete, and the supply and drain plumbing was not worth reconnecting to a new tub.
The job became a full gut. In Will's words, the electrical was "fully replaced" by the licensed electrician Bytown subcontracts for that work, a complete new plumbing rough-in went in, and the exterior walls received new insulation and a vapour barrier before the new tub and wall system were installed. What did not need work was the structure. That is the pattern in most 1950s and 1960s houses: the framing is sound, and it is the systems inside the wall that have reached the end of their life.
Three things follow for a Westboro homeowner. First, a job like that is not a 1 to 3 day install and is not $13,000 to $15,000 CAD; it is priced as a complete renovation, from $20,000 CAD, with the electrical and rough-in as their own lines. Second, none of it could have been quoted from photos. Third, the change was put in writing and approved before the extra work started. If a contractor tells you an older Westboro house is a guaranteed one-day job before demolition, they are guessing.
One more concession: if the house still has active knob-and-tube or a panel that cannot safely take a bathroom circuit, that is a whole-home electrical project first, and a licensed electrician, not a bath and shower contractor, is who you call.
When to check with the City of Ottawa before work starts
Westboro is inside the City of Ottawa, so permits follow exactly the same rules as every other Ottawa address. There is no separate Westboro process, and the neighbourhood is not a heritage conservation district; individual properties can be on the City's heritage register, and if yours is, that affects exterior changes rather than a bathroom interior. The technical standard is the Ontario Building Code, and the City of Ottawa reviews and inspects against it.
As a rule of thumb, a like-for-like tub or shower replacement in the same location does not normally trigger a building permit, while moving plumbing, altering walls or changing the electrical does. In an older Westboro home the second list comes up more often, because a new rough-in and a rewired circuit are exactly what an inspector needs to see before the wall is closed. Our guide to bathroom renovation permits in Ottawa explains what the City looks for, and Bytown's subcontracted electrical work is pulled under the electrician's own permit.
How to check any Westboro bathroom quote yourself, in four steps
Step 1: Ask whether the quote was priced from photos or from a site visit
For a house built before 1970 a quote from photos is a starting guess. A contractor who has opened up older Ottawa walls will want to see the room, the panel and the basement plumbing before committing to a number.
Step 2: Ask what happens when demolition finds galvanized pipe or old wiring
The answer you want is a written change-order process with your approval before extra work starts, and a stated price for the likely items: supply line replacement, a new circuit, insulation and vapour barrier. A verbal "we'll sort it out" is how a $13,000 CAD job becomes an argument.
Step 3: Ask who does the electrical and under whose permit
Bathroom electrical in an older home is licensed-electrician work. Get the electrician's name and confirm the work is permitted. A contractor who says their own crew will "handle the wiring" without a licensed electrician is a contractor to walk away from.
Step 4: Ask for the warranty term as a number
"Written warranty" means nothing without a number of years. Bytown's is 5 years on labour and supplied materials. Whatever contractor you talk to, get their number in the quote document itself.
Run those steps on us
Step 1: Bytown quotes older homes after an in-home visit. Step 2: written change orders, approved by you first; the Britannia example above is what that looks like in practice. Step 3: a licensed electrician subcontractor, fully permitted. Step 4: 5 years, labour and supplied materials, in the written quote. The step we do not pass cleanly is step 2: we cannot tell you before demolition what a pre-war wall contains, so our first number on an older Westboro house is honestly a band, not a fixed price.
What Bytown does not offer, and why that matters
Three limits worth knowing before you call, because they decide whether Bytown is even the right fit for your Westboro project.
No bathtub reglazing or refinishing. Many Westboro homes still have an original cast iron tub, and if it is structurally sound and the goal is purely cosmetic, reglazing at a few hundred dollars is the cheaper route and Bytown does not sell it. Call a dedicated refinisher instead. Bytown's work starts where the tub or surround is being replaced.
A whole-home rewire is not a bathroom job. If the panel and the wiring throughout the house are original, an electrician needs to bring the house up first. Bytown's electrician handles the bathroom circuit as part of a renovation, not the rest of the house.
Layout changes and full gut renovations are not a 1 to 3 day job. The guaranteed 1 to 3 day window applies to tub and shower replacement in the existing footprint. If plumbing is moving or the whole room is being redesigned, that is a longer project priced from $20,000 CAD on Bytown's complete bathroom renovation service, and for a design-build project across several rooms a general contractor is often the better first call.

The Truth About Bathroom Remodel Costs
Where this renovation advice applies
Bytown Bath's core service areas are Ottawa, Kanata, Nepean, Barrhaven, Orleans and Gatineau, and Westboro sits inside Ottawa itself, so every price band on this page applies with no travel line. The older-home advice applies wherever the house is old: a 1950s bungalow in Nepean behaves the same behind the wall as one in Westboro. Newer subdivisions in Kanata, Barrhaven and Orleans have a different set of surprises, mostly 1990s piping, and are covered on their own pages.
Gatineau is the other special case: it is in Quebec, where contractor licensing and permitting follow Quebec rules rather than the Ontario Building Code, so nothing in the permit section above applies there. Confirm locally, or call us and we will point you at the right office.
Bathroom renovation Westboro: questions homeowners ask
How much does a bathroom renovation cost in Westboro?
The same as anywhere in Ottawa on Bytown's published bands, checked September 4, 2026: a tub-to-shower conversion or bathtub remodel runs $13,000 to $15,000 CAD, a shower remodel starts from $13,000 CAD, and a complete bathroom renovation starts from $20,000 CAD. In a pre-war or 1950s Westboro home, galvanized pipe, old wiring or missing insulation found after demolition is added as a written change order, so budget with a band rather than a single figure.
Do older Westboro homes need rewiring before a bathroom renovation?
Sometimes. If the bathroom circuit is obsolete, Bytown's licensed electrician subcontractor replaces it as part of the renovation, under permit. If the whole house is still on knob-and-tube or an undersized panel, that is a whole-home electrical project for an electrician first, and it is not part of a bathroom quote. A site visit that includes a look at the panel is how you find out before demolition rather than after.
Do I need a permit for a bathroom renovation in Westboro?
It depends on scope, and the rules are the City of Ottawa's, applied under the Ontario Building Code, with no separate Westboro process. A like-for-like tub or shower replacement in the same location does not normally need a building permit. Moving plumbing, altering walls or replacing electrical does, and electrical work is permitted by the licensed electrician doing it. Westboro is not a heritage conservation district, so only individually listed properties carry extra rules, and those concern the exterior.
How long does a bathroom renovation take in an older home?
A tub or shower replacement in the existing footprint carries Bytown's guaranteed 1 to 3 days on site, in Westboro as anywhere else. If demolition turns the job into a gut with new electrical, a new rough-in and insulation, as it did on a recent Bytown job in the Britannia area, it becomes a complete renovation scheduled per scope, and the new timeline is put in writing before the extra work starts.
Can you renovate a very small bathroom in a Westboro home?
Yes. Many pre-war Westboro bathrooms are under 50 square feet, and a tub-to-shower conversion or bathtub remodel fits inside that footprint without moving walls. The small size does not lower the $13,000 to $15,000 CAD band much, because the fixture, wall system and removal labour are the same, but it does limit what can move, so the layout is decided on site.
