That jetted tub has been empty since the day you moved in
Bolton’s hills filled with houses through the eighties and nineties, and the ensuites came standard with a corner jacuzzi nobody has filled this decade. It squats on prime floor space while everyone lines up for the shower.
The renovation this town asks Senso Design for most is exactly that swap, the tub footprint surrendered to a generous glass shower, the vanity rebuilt with storage that actually works, and floors warm enough for a Caledon February. The room gets younger by thirty years without moving a single wall.
Family bathrooms follow their own logic. Kids are hard on grout, silicone and vanity doors, so we build those rooms around materials that forgive, porcelain over natural stone, quality fixtures over fashionable ones, and a fan that actually clears the mirror.
Tile is the jewellery. The membrane behind it is the roof.
Every bathroom that fails, fails invisibly first. Water finds its way past pretty tile through whatever corner the last crew skipped, and the ceiling below finds out a year later.
- A continuous waterproofing system goes behind every Senso Design shower, wrapped and sloped before tile is even ordered. It is the least photogenic money in the project and the most important.
- Plumbing gets renewed while the walls are open. Shutoffs, supply lines and the drain connections date from the same year as the tub, and this is the cheapest moment they will ever have to be replaced.
- Ventilation is sized, not assumed. A correctly ducted fan is the difference between a bathroom that dries and one that grows things.
- Heated floors earn their keep here. An electric mat under the tile adds a modest line to the budget and pays it back every winter morning in this part of Ontario.
- Rural properties get planned differently. Around Bolton’s edges some homes run on wells and septic, so fixture flows and construction water use get thought through rather than discovered.
- Fixtures are specified in writing. Brand, model and finish on the quote, so the comparison shopping you do is against real products, not allowances that shrink.
What a bathroom renovation costs in Bolton
Senso Design’s 2026 ranges, before 13% HST. The line by line version lives in our bathroom cost guide.
| Project | Typical range | What pushes it higher |
|---|---|---|
| Powder room | $5K to $12K | Designer fixtures, wallpaper and millwork |
| Standard full bathroom | $12K to $25K | Relocating the toilet, custom glass |
| Tub to walk in shower conversion | $14K to $25K | Linear drains, bench seating, full height tile |
| Primary ensuite | $25K to $70K+ | Curbless entry, freestanding tub, double vanity, stone |
The pattern worth knowing: labour and waterproofing eat more than half of a bathroom budget, which is why two quotes with identical fixtures can sit thousands apart. The cheaper one is usually thinner exactly where you cannot see it.
Put a ballpark on your Bolton bathroom
Choose the room. The bands come straight from the table above, with 13% HST added so the honest number is the one you remember.
Bands reflect completed Senso Design bathrooms across the GTA. Moving fixtures, custom glass and natural stone push any room toward the top of its band.
A compass, not a contract. A walk through your actual bathroom turns it into a real number, free and without obligation.
When a Bolton bathroom needs a permit, and when it does not
- Same layout, no permit. Swapping the tub, vanity, toilet and tile where they already sit generally needs no paperwork at all.
- Moving drains changes that. Relocating the toilet or shower, or adding a bathroom where none existed, brings a Town of Caledon permit into the project.
- Electrical work is notified to ESA, with GFCI protection standard in wet areas.
- Older core homes get inspected first. Galvanized supply lines and tired shutoffs live in Bolton’s village-era houses, and we look before demolition, not during.
- Senso Design carries the paperwork where any is needed, filed in our name with inspections attended by us.
- Construction runs 2 to 4 weeks for a standard bathroom, longer when the layout moves, and we sequence tightly when it is the only bathroom in the house.

“It looked perfect for a year. Then the ceiling stained.“
The saddest call we get, and it is always the same story, beautiful tile over skipped waterproofing. Ask every bidder to name the membrane system in their quote. A blank stare answers the question.

What clients say
A 4.9 average across 115+ Google reviews, with Best of HomeStars five years running and Best of Houzz in 2025 and 2026.
The teams were well coordinated, small issues were resolved quickly, and the final cost matched the original quote. That last part is rarer than it should be.
Mark patiently explained everything to us, from planning, design, choices of materials and timeline. Everything went extremely well, from a great design and layout to the hardworking, efficient, well mannered construction crew. The finished product looks fantastic.
We did a major renovation, kitchen, multiple baths, family room, and still love the work they did. From incorporating new ideas to sticking to budget and timelines, they were on point. Their after care has also been superb.

Bolton bathroom questions, answered
How much does a bathroom renovation cost in Bolton?
From Senso Design’s 2026 files: powder rooms run $5,000 to $12,000, a standard full bathroom $12,000 to $25,000, and a primary ensuite $25,000 to $70,000 or beyond, before HST. A tub to walk in shower conversion, the most requested project on Bolton’s hills, typically lands between $14,000 and $25,000 depending on tile and glass.
What does it cost to swap a corner tub for a walk in shower?
Budget $14,000 to $25,000 for it done properly, meaning full demolition of the tub deck, a wrapped and sloped waterproofing system, tile to the ceiling and real glass. The corner units of the nineties leave a generous footprint behind, which is why the finished showers feel almost indulgent. Linear drains, benches and niches nudge the price up within that band.
Which finishes are worth the money in a family bathroom?
Spend where hands and water touch daily, the shower valve, the fan, the vanity hardware and the waterproofing you will never see. Save on the parts fashion changes fastest, accent tile and mirrors swap cheaply later, a relocated drain does not. Porcelain earns its place over natural stone in kids’ bathrooms because it shrugs off everything.
Do I need a permit for a bathroom renovation in Bolton?
Not if everything stays where it is, which covers most projects. The Town of Caledon gets involved when drains move, when a bathroom is added where none existed, or when walls change. Electrical goes through ESA notification either way. When paperwork applies, Senso Design files it under our own name and meets the inspector so you never have to.
How long will my bathroom be out of service?
Two to four weeks of construction for a standard rebuild, and we say so up front because a household plans around its bathrooms. If it is your only one, tell us at the quote stage, we sequence those jobs to keep the toilet usable as deep into the build as physically possible and compress the rest.
My home near Bolton is on a well and septic. Does that change the renovation?
It changes the planning more than the bathroom. Fixture choices respect the septic system’s appetite, construction water use gets managed, and nothing about the design fights the way rural plumbing behaves. Plenty of properties around Palgrave, Albion and Castlederg run this way, and it has never stopped a beautiful bathroom.
Are heated bathroom floors worth it in Caledon winters?
Ask anyone who has them in February. An electric mat under the tile is a modest add during construction, impossible to retrofit cheaply afterward, and it turns the coldest room in the house into the warmest. Of every upgrade we install, it earns the most unprompted thank you messages.
Why do bathroom quotes vary so much for the same room?
Because more than half the cost is labour and hidden layers, and that is where thin quotes go thin. One bidder includes membrane waterproofing, new supply lines and disposal, another leaves them out and looks cheaper for it. Line up the quotes item by item, and where one goes quiet, that silence is your answer.
How do I get an exact price?
Book the free consultation. We measure the room, check the plumbing behind it, and send a budget range within five business days, followed by a line itemized fixed price if you move to design. That price includes waterproofing, fixtures by model and disposal, and it is what you pay at handover.
