How much does it cost to replace a shower kit in Toronto?

Hi, I'm Chris, a General Contractor with 25 years in residential renovations. Happy to help you scope and price a swap of your shower kit for that clean chrome look!

From your photo, it's a great-looking setup. The plumbing fixtures themselves — the overhead rain head, hand shower, control valve, and bottom spout — are actually a gold/brass finish, while the glass shower-door frame and the recessed niche are black.

Before we get into specifics, I want to nail down exactly what's being replaced and grab a few details so we can build an accurate scope.

Question: What is your postal code?

Question: Are we swapping only the plumbing fixtures (shower head, hand shower, valve dial, and bottom spout), or do you also want to change the black pieces like the shower glass frame and the recessed niche?

• Only the plumbing fixtures — swapping gold for chrome
• The plumbing fixtures plus the black shower-door frame/niche
• The plumbing fixtures and the shower door, but keep the niche

Question: Do you know the brand of the current shower fixtures, or are you planning to replace the valve behind the wall too?

• Replace the in-wall valve — lets us use any brand, may mean opening wall/tile
• A trim-only swap — must match the existing brand, no wall demo
• I'm not sure — let's assume we are replacing the valve to be safe

Question: Who's supplying the new chrome shower kit?

• I'll buy and provide the new chrome kit — contractor installs only
• Have the contractor provide a standard/mid-range chrome kit

Photos that would help

To confirm the technical setup and keep costs down, a couple of extra photos would be great:

• A close-up of the main control dial/handle: there's often a small brand logo (Moen, Delta, Kohler, or Grohe) stamped on the faceplate or dial that tells us whether a simple trim swap is possible.
• The wall directly behind the shower: if the shower backs onto a closet, hallway, or bedroom wall, let me know — it's usually far cheaper to cut a small access hole in the back drywall to change a valve than to cut into your nice shower tile.

Thanks — that gives us a clear path. Since we're changing the valve behind the wall so you can use any new chrome kit you like, a licensed plumber will need to physically reach the pipe connections inside the wall.

Because this is in-wall plumbing work in Toronto, a few structural and logistical questions will help us estimate the exact trade hours and any prep:

Question: What type of home is this (detached house, townhouse, or condo)?

• A detached house
• A townhouse
• A condo/ apartment building

Question: Is there drywall access on the wall directly behind the shower (inside a closet, hallway, or adjacent bedroom), or is the only way in from the front through the tile?

• Yes — there's drywall behind that shower wall (closet/bedroom/hallway)
• No — tile-only access, so we'd cut the front shower tiles
• Not sure — let's assume drywall access from behind is possible

Question: Roughly what year was your home built?

• Before 1990 — asbestos testing needed before disturbing drywall or tile
• 1990 or later — asbestos testing usually isn't required
