Bathroom renovation cost is one of the most searched questions we see from Brantford homeowners — and also one of the most poorly answered. Most online guides give coast-to-coast Canadian averages that don't reflect what trades, materials, and permits actually cost here in Brant County. So let's fix that.
Below are real ranges based on projects we've completed in Brantford, Paris, and the surrounding area. Your number will land somewhere in these ranges depending on scope, finishes, and whether there are any surprises behind the walls.
Bathroom renovation cost in Brantford: the ranges
| Scope | Typical Cost | What's included |
|---|---|---|
| Cosmetic refresh | $8,000 – $15,000 | New vanity, toilet, mirror, light fixture, paint. No tile work, no plumbing moves. |
| Mid-range renovation | $18,000 – $30,000 | Full gut to studs, new tile, tub or shower replacement, updated plumbing fixtures, drywall, exhaust fan. |
| Full renovation with layout change | $30,000 – $50,000+ | Everything above plus moving plumbing, adding a double vanity, walk-in shower with custom tile, heated floors. |
| Primary ensuite (luxury) | $45,000 – $75,000 | Large format tile, freestanding tub, steam shower, double vanity with custom cabinetry, in-floor heat. |
These are all-in numbers: labour, materials, permit (where required), and a reasonable contingency. They assume a standard 50–80 sq ft bathroom. A powder room or small 3-piece will come in lower; a large primary ensuite will come in higher.
What drives bathroom renovation costs in Brantford
The single biggest cost driver isn't the tile you pick — it's what happens when we open the walls. Older Brantford homes (especially anything pre-1980) frequently have cast iron drain lines that need partial replacement, knob-and-tube or aluminum wiring that has to be brought up to code before we can close up, or subfloor rot from a slow leak that's been sitting for years. None of that shows up in a quote until we're in.
A well-run renovation includes a contingency line of 10–15% for exactly this reason. If you're being quoted a flat price with no allowance for unknowns, push back on that.
Other cost drivers:
- Tile complexity: Large format tile (24"×24" and up) costs more to install than standard 12"×12" — more cuts, more waste, more time. Feature walls and herringbone patterns add further.
- Plumbing moves: Keeping your drain, toilet, and supply lines in the same location saves $2,000–5,000. Moving the toilet across the room is a significant cost.
- Shower system: A basic alcove tub/shower with a single valve runs $800–1,200 in materials. A Schluter-system custom shower with a thermostatic valve and body sprays runs $4,000–8,000 in materials alone before labour.
- Permits: Brantford requires a building permit for structural work and a separate plumbing permit if you move or add drain lines. Budget $500–1,000 for permits on a mid-range reno.
Is it worth renovating a bathroom before selling?
In most cases, yes — but the return depends on what the rest of the house looks like. A dated bathroom in an otherwise updated home is a deal-killer for buyers. Fixing it brings you back to baseline, which is worth doing. A luxury renovation in a home where everything else is original is harder to recoup.
The sweet spot for resale is a clean, neutral mid-range renovation: white or light grey tile, a walk-in shower if space allows, quality fixtures, and good lighting. You don't need to go high-end to make a strong impression — you just need it to feel fresh and well-built.
The renovation that photographs well and feels solid underfoot will always outperform the one with the fanciest fixtures. Buyers notice quality of execution before they notice brand names.
How long does a bathroom renovation take in Brantford?
A mid-range bathroom renovation — full gut, new tile, new fixtures — typically takes 2–3 weeks of active work once trades are scheduled. That's not 2–3 weeks from the day you sign; scheduling tradespeople (plumber, electrician, tile setter) in Brant County can add 4–8 weeks to your lead time depending on the season.
Spring and fall are our busiest periods. If you want a summer bathroom renovation, the time to call is February or March. If you're flexible on timing, winter slots often come with faster scheduling and occasionally better subcontractor availability.
Cost breakdown by bathroom type
Not all bathrooms cost the same to renovate. Here's a more granular look at what different bathroom types cost in Brantford in 2026:
| Bathroom type | Typical cost | Key factors |
|---|---|---|
| Powder room (2-piece) | $6,000 – $14,000 | Small footprint; no shower; mostly fixtures and finishes |
| 3-piece (shower only) | $16,000 – $30,000 | Shower waterproofing, tile, vanity, toilet; plumbing stays in place |
| 4-piece (tub + shower) | $20,000 – $38,000 | More tile work, tub surround or separate shower; full gut typical |
| Primary ensuite | $40,000 – $75,000+ | Walk-in shower, double vanity, freestanding tub, in-floor heat, custom tile |
What's behind the walls: the hidden cost factor
In older Brantford homes — anything pre-1985 — opening up a bathroom reveals a wide range of conditions. Here's what we commonly find, and what it means for your budget:
- Subfloor rot from slow leaks. Failed caulking around a tub or shower, left for years, quietly rots the plywood subfloor beneath. Replacing a wet subfloor section adds $800–$2,500 depending on extent.
- Cast iron drain lines. Older homes often have cast iron stack and drain pipes. These can last decades more, but if they're cracked, scaled, or improperly sloped, we may need to tie into them with new ABS — an additional $1,500–$4,000 in plumbing.
- Knob-and-tube or aluminum wiring. If your home has this, it needs to be addressed before the bathroom is enclosed — the electrical code requires it. Budget $1,500–$3,000 for the electrical portion of the work.
- No vapour barrier or improper waterproofing. Older bathrooms often have drywall behind tile with no membrane protection. Any bathroom gut-to-studs renovation should include proper Schluter KERDI or equivalent waterproofing system.
None of these conditions are rare — they come up on a significant portion of Brantford bathroom renovations in homes built before 1990. A well-structured quote includes a contingency line of 10–15% to absorb them without a shock change order.
Permit requirements for bathroom renovations in Brantford
Not all bathroom renovations require a permit in Brantford. The rules are:
- No permit needed for cosmetic work: replacing fixtures, vanity, mirror, toilet, or repainting — as long as you're not touching the plumbing rough-in.
- Plumbing permit required if you're moving or adding drain lines, or adding any new plumbing rough-in.
- Building permit required for structural changes, adding a bathroom where there wasn't one, or adding an egress window.
Permit fees for a standard bathroom renovation in Brantford typically run $500–$1,200. We manage the application and inspection process on your behalf — you don't need to navigate the City of Brantford or Brant County building department yourself.
