Shower Leak Repair Cost in 2026: Toronto and GTA Prices (CAD)
Toronto plumber prices for valves and leak detection, GTA tile shop prices for silicone and regrouting, shower base and full shower prices, and what the ceiling below costs to fix.
Most shower leak repairs in Toronto cost $200 to $700 when the fix is a valve cartridge, a diverter or new silicone, based on 2026 GTA price lists from Tornado Plumbing and TilesRus. A shower leak is water escaping through a worn valve, failed caulk or grout, a cracked base or broken waterproofing, often showing up as a stain on the ceiling below. Leaks behind tile or under the pan cost more, from $900 to several thousand dollars. To get local quotes, start with our plumbing repair services.

How much does shower leak repair cost in Toronto and the GTA?
The price depends on where the water escapes. A drip from the shower head or spout usually means a cartridge or diverter, which Toronto plumbers price at $130 to $450. A leak that shows on the ceiling below can come from the valve, the drain, failed silicone or grout, or broken waterproofing, and finding it may cost $250 to $700 before the repair starts.
| Repair | Typical cost | Source |
|---|---|---|
| Shower cartridge replacement | $220 to $450 | Tornado Plumbing |
| Shower cartridge replacement, part and labour | $130 to $280 | Delex Plumbing |
| Diverter or tub spout repair | $200 to $400 | Tornado Plumbing |
| Silicone replacement | $299 plus HST | TilesRus |
| Full shower valve replacement (valve body and trim) | $350 to $700 | Delex Plumbing |
| Pressure-balance valve replacement | $650 to $1,500 | Tornado Plumbing |
| Full valve replacement with wall access | $900 to $2,400 | Tornado Plumbing |
| Full regrouting | $1,553.57 plus HST | TilesRus |
Opening the wall is what moves a valve job into the thousands. Tornado Plumbing starts a full valve replacement with wall access at $900, while an accessible cartridge swap starts at $220. If the valve sits behind a removable access panel, say so when you ask for quotes, because it can keep the job at the low end.

How much does it cost to find a hidden shower leak?
A leak detection visit in Toronto costs $250 to $500, and acoustic or moisture mapping $300 to $700, says Tornado Plumbing. Once the source is found, a hidden pipe repair through a small opening runs $400 to $1,200. Paying for detection first can save money, because it limits how much tile or drywall has to come out.
| Service | Starting from | Typical range |
|---|---|---|
| Leak detection visit | $250 | $250 to $500 |
| Acoustic or moisture mapping | $300 | $300 to $700 |
| Hidden pipe repair (small opening) | $400 | $400 to $1,200 |

A real GTA example shows how one leak adds up. RenoHeal describes a Markham job with a recurring leak through the ceiling below, traced to a failed corner seam in the shower. The crew cut tile, replaced the corner waterproofing, re-tiled, regrouted and re-caulked, and a licensed plumber checked the valve. It took 3 days and cost $2,400 (RenoHeal).
How much does it cost to reseal or regrout a leaking shower?
Failed silicone or grout is one of the cheaper causes to fix. TilesRus in Toronto charges $299 plus HST to replace silicone when the tile and grout are sound, and $1,553.57 plus HST for premium regrouting of cracked or missing grout. Silicone work takes about 2 to 3 hours, and regrouting 7 to 9 hours.
| Package | When it fits | Price |
|---|---|---|
| Silicone replacement | Silicone mouldy or separating, tile and grout fine | $299 plus HST ($337.87 with HST) |
| Cleaning plus silicone | Grout stained but intact | $599 plus HST ($676.87 with HST) |
| Cleaning, silicone and grout sealing | Grout intact, sealer wanted | $698 plus HST ($788.74 with HST) |
| Premium regrouting | Grout cracked, missing or deteriorated | $1,553.57 plus HST ($1,755.53 with HST) |

New grout and caulk will not fix a leak if the waterproofing behind the tile has failed, as in the Markham corner seam job above. If water keeps showing below after a reseal, ask for a leak test before paying for more surface work. For how often plumbing failures happen, see our plumbing statistics.
How much does it cost to replace a shower pan or the whole shower?
A cracked base or failed pan usually means replacing it. Cheap Plumber Toronto starts shower base installation at $650, or $750 in a condo, with a starting labour rate of $450 for a standard acrylic, fibreglass or tiled base. When the walls have to come out too, RenoHeal prices a prefab kit install at $1,800 to $3,500 and a custom tile shower at $5,000 to $9,000.
| Job | Typical cost | Source |
|---|---|---|
| Shower base installation, labour from | $450 | Cheap Plumber Toronto |
| Shower base installation, house | From $650 | Cheap Plumber Toronto |

| Tub-to-shower conversion | $3,500 to $7,000 | RenoHeal |
| Custom tile shower with waterproofing | $5,000 to $9,000 | RenoHeal |
RenoHeal notes that its custom tile showers can reach $12,000 depending on size and tile, and that a like-for-like shower replacement usually needs no permit, while new plumbing can. If the leak has damaged the subfloor or framing, the job turns into a bathroom renovation; see our bathroom renovation cost guide for GTA prices.

Toronto Drywall Pro prices a single water-damaged ceiling spot at $400 to $800, multiple damaged panels at $800 to $1,600, and a condo upstairs-leak ceiling repair at $600 to $1,400.

How do you get an accurate shower leak quote?
Tell the plumber when the leak appears: only while the shower runs, only when water hits the glass or walls, or all the time. Send photos of the shower, the valve trim and any ceiling stain, and say whether there is an access panel. Ask whether detection is credited to the repair and whether the price is fixed.
