The tub to shower conversion cost Toronto homeowners pay depends far less on the shower itself than on what is hiding behind your bathroom walls. As a typical range, converting a tub to a shower adds roughly $3,500-$7,000 to a bathroom project, and where you land in that range comes down to plumbing, waterproofing, tile and glass. Every home is different, and the most reliable number comes from a site visit, but the points below explain why prices vary.
What a conversion actually involves
People often imagine swapping one fixture for another in a day. In practice, a proper conversion means removing the tub and the surrounding wall finish, assessing the framing and subfloor, changing the drain to suit a shower base, relocating the valve and shower head, building a waterproof assembly, and finishing with tile and glass or a curtain.
Tubs sit in an alcove, but showers can be built in nearly any footprint. That freedom is a design bonus, since you can often make the shower larger by pulling the glass or the wall back into the room, but it also means decisions about layout have to be made before the plumber rough-ins.
What drives tub to shower conversion cost Toronto contractors quote
- Drain and plumbing changes. A shower drain sits in a different place from a tub drain. If the floor framing is easy to reach from below, such as above an unfinished basement, the work is simpler. If the ceiling below is finished, access costs more.
- Waterproofing method. A proper membrane system, whether sheet or liquid, is the part you never see and the part that matters most. A cheap job skips or rushes it.
- Tile size and pattern. Large-format tile has fewer grout lines but needs a flatter wall. Small mosaic tile on the floor is easier to slope to the drain but takes longer to lay.
- Glass. A fixed panel, a hinged door and a custom frameless enclosure are priced very differently. Custom glass is also made after measurements, so it affects schedule.
- Fixtures. A basic valve and head cost much less than a thermostatic or rain-style system with body jets.
- Surprises. Old homes often reveal rot, undersized drains, or outdated galvanized supply lines once the tub is out.
Waterproofing is the line item not to cut
Showers fail when water gets behind the tile. The tub was forgiving because the tub itself was the waterproof layer. A shower is different: the pan, curb and walls need a continuous membrane, sloped correctly toward the drain, tested for leaks before tile goes on. Ask any contractor you interview how they waterproof and how they test. A flood test of the shower pan, left in place for a period before tiling, is a sign of a careful trade.
If a quote is far below others, the missing item is often the membrane, the pan test or the proper backer board. Those omissions cost a great deal more later than the savings they provided up front.
Standalone conversion or part of a bathroom renovation?
If the rest of the bathroom is tired, converting only the tub is rarely the most economical plan. You have already opened the walls and brought in a plumber and tile setter, so extending the work to the floor, the vanity and the lighting often costs less than doing it separately later. For orientation, typical ranges are $18,000-$35,000 for a main bathroom, and an ensuite runs about $28,000-$55,000, with the tub-to-shower conversion adding roughly $3,500-$7,000 on top when you choose it. Our guide to bathroom renovation cost in Toronto explains how those budgets break down.
A standalone conversion makes sense when the vanity, flooring and fixtures are in good shape and you simply need safer or more usable bathing.
Accessibility and aging in place
Many conversions in Toronto are about safety rather than style. A low-threshold or curbless shower, a built-in bench, grab bars that are properly anchored into blocking inside the wall, and a handheld shower head all make daily use easier. If there is even a small chance you will need these later, install the blocking now while the walls are open. It costs very little compared to opening the walls again.
Slip resistance matters, too. Smaller floor tiles with more grout lines provide natural traction, and a matte finish is generally safer than polished stone or glossy porcelain.
Timing and permits
A conversion that stays within the existing plumbing and does not alter structure is usually simple, but moving drains, altering framing or adding fixtures may involve a permit. Rules vary by project, so confirm with the City of Toronto building department. Ask your contractor to be upfront about whether a permit applies and who will handle it. Our bathroom renovation page outlines how we plan, and if you live in the east end, the Scarborough bathroom renovation page covers local projects.
Plan on several days to a couple of weeks of on-site work, depending on scope, with extra lead time for custom glass.
Frequently Asked Questions
Is it possible to keep a tub in the house and still add a shower?
Yes. If you have two bathrooms, many households convert one and keep a tub in the other for children or resale appeal.
Will converting a tub reduce resale value?
It depends on the home and buyer expectations. Keeping at least one bathtub in the house is a common consideration, so think about the whole property before removing the last one.
How long before the shower can be used?
After tiling and grouting, sealers and caulk need time to cure. Your installer will give you the specific waiting period for the products used.
Is a curbless shower possible in any bathroom?
Often, but it depends on the floor framing and drain location, since the floor has to be recessed to slope water to the drain. A site visit will answer that.
