Shower Valve & Trim Replacement Cost in Vancouver

Hi, I'm Chris, a General Contractor with 25 years of experience in residential renovations. I can certainly help you scope out and estimate replacing your shower kit to get that clean chrome look!

Looking at the photo you provided, you have a beautiful setup. The plumbing fixtures themselves (the overhead rain shower, hand shower, control valve, and bottom spout) are actually a gold/brass finish, while the glass shower door frame and the recessed shelving niche are black.

Before we dive into the details, I want to clarify exactly what we're replacing and gather a few details so we can build an accurate scope of work.

Question: What is your postal code?

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

• Plumbing fixtures only (changing gold to chrome)
• Plumbing fixtures AND the black shower door frame/niche
• Plumbing fixtures and the shower door, but keep the niche

Question: Do you know the brand of the existing shower fixtures, or do you plan to replace the valve behind the wall as well?

• I want to replace the valve behind the wall (allows any new brand, may require opening wall/tile)
• I want to do a trim-only swap (must match existing brand, no wall demolition)
• I'm not sure — let's assume we are replacing the valve to be safe

Question: Who will be supplying the new chrome shower kit?

• I will buy and supply the new chrome kit (Contractor install only)
• I want the contractor to supply a standard/mid-range chrome kit

Photos that would help

To help confirm the technical setup and keep costs as low as possible, a couple of extra photos would be fantastic:

• A close-up of the main control dial/handle: Often, there is a tiny brand logo (like Moen, Delta, Kohler, or Grohe) stamped on the faceplate or dial which tells us if we can do a simple trim swap.
• The wall directly behind the shower: If this shower backs onto a closet, hallway, or bedroom wall, let me know! It is often much cheaper to cut a small access hole in drywall on the back of the wall to swap a valve than it is to cut into your beautiful shower tile.

Thanks for those details! That gives us a clear path. Since we are changing the valve behind the wall to allow for any new chrome kit of your choice, a licensed plumber will need to physically access the pipe connections inside the wall.

Because we are doing in-wall plumbing work in Vancouver, we have a few structural and logistical questions to pin down so we can estimate the exact trade hours and any required preparation:

---

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

• Detached House
• Townhouse
• Condo/ Apartment building

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

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

Question: Approximately what year was your home built?

• Before 1990 (Requires asbestos testing before disturbing drywall or tile)
• 1990 or later (Asbestos testing is not typically required)
