The shower is the part of the bathroom that fails
Vanities get dated. Showers get wet, and then they get expensive. Almost every ceiling stain we are called to look at traces back to a shower built without a real membrane, without slope, or with the drain flange never properly bonded. We build them so that does not happen, and we flood-test the pan before a single tile goes on. Doing the whole room instead? Start at bathroom renovation in Toronto & GTA.

Shower types, cost & timeline in Toronto (2026)
| Type | Cost range | Timeline | What it involves |
|---|---|---|---|
| Tub-to-shower conversion | $9,000–$15,000 | 1.5–2 weeks | Tub out, new sloped tray or pre-formed base, sheet membrane, wall tile to ceiling, glass panel, valve and head. Drain moves a few inches to centre, which means a permit in most cases. |
| Rebuild an existing shower stall | $8,000–$14,000 | 1–2 weeks | Strip the failed stall to studs, replace substrate and membrane, new tile, niche, fixtures, and glass in the same footprint. |
| Curbless walk-in shower | $14,000–$24,000 | 2–3 weeks | Joists notched or a recessed pan set into the floor so the tile runs flat through the opening, linear drain, sheet membrane, frameless glass. Needs joist access from below. |
| Wet room (shower + freestanding tub) | $22,000–$38,000 | 3–4 weeks | The whole zone waterproofed, one drain or two, floor-to-ceiling tile, glass screen, and usually heated floor since the area is large enough to feel cold. |
How we build a shower
- 1
Demolition and inspection of the cavity
Old showers fail from the bottom up. Once the tile is off we look at the subfloor at the drain, the bottom plate, and the studs. Rot here is common in Toronto houses built before 1970 and it is cheaper to find on day one than after the tile is on.
- 2
Drain, slope, and blocking
A pre-sloped tray or a mud bed at a minimum quarter-inch per foot to a bonded-flange drain. Blocking goes in for the bench, the grab bar you may want later, and the glass panel bracket. Adding blocking now costs almost nothing; adding it later means opening the wall.
- 3
Sheet waterproofing, then a flood test
Kerdi or equivalent sheet membrane over cement board, corners and the drain flange banded. Then we plug the drain and fill the pan and leave it. If it holds overnight, we tile. This step is the difference between a shower and a slow leak.
- 4
Tile, with the layout set before the first sheet
Where the cuts land is decided before anything is stuck down — full tiles at eye level, cuts at the floor and in corners, the niche coursed into the pattern rather than dropped in wherever it fit.
- 5
Glass measured after tile, not before
Frameless glass is templated on the finished tile, then fabricated. That is a 7–10 day gap you should expect in the schedule. Anyone quoting glass installed the same week as tile is quoting a stock panel, which is fine — just know which one you are buying.

Shower renovation in Toronto - questions
How much does a shower renovation cost in Toronto?
Rebuilding an existing stall runs $8,000–$14,000. A tub-to-shower conversion is $9,000–$15,000. A curbless walk-in is $14,000–$24,000 because the floor structure has to be modified. A full wet room with a freestanding tub is $22,000–$38,000.
How long does a shower renovation take?
One to three weeks depending on type, plus a 7–10 day wait for frameless glass fabrication after tile is finished. The membrane flood test takes a night, and thinset and grout need their cure time. That is why a shower cannot honestly be done in three days.
Do I need a permit to convert a tub to a shower?
In Toronto, yes if the drain moves — and it almost always moves, because a tub drain sits at one end and a shower drain sits at the centre. A straight like-for-like stall rebuild with no plumbing relocation does not need one. We pull it either way when it applies.
Can I get a curbless shower in a condo?
Rarely. A curbless floor needs recessed structure or a raised floor, and a concrete condo slab gives you neither without eating ceiling height. What works instead is a very low-profile curb, a linear drain at the wall, and a full-height glass panel — visually close, structurally possible.
Why does my current shower leak into the ceiling below?
Almost always one of four things: no real waterproofing behind the tile, a failed or unbonded drain flange, a shower pan with no slope, or unsealed corners where the wall meets the floor. Regrouting fixes none of them. The tile has to come off.
Is a shower renovation worth doing on its own?
If the rest of the bathroom is in decent shape, yes — it is the fixture people use daily and the one that fails. If the vanity, floor, and fan are also original, doing the whole room at once costs maybe 40% more than the shower alone and saves a second round of demolition and dust.
