What Does Bathroom Remodel Plumbing Cost in Metro Detroit?

Bathroom remodel plumbing is one of the most variable line items in a renovation budget. A simple fixture swap in a bathroom with good existing plumbing is very different from a full gut-and-rebuild with new supply lines, new drain-waste-vent rough-in, and a relocated toilet.

Here's a realistic breakdown for Metro Detroit. A basic fixture replacement — toilet, vanity faucet, and showerhead in an existing bathroom with no layout changes — typically runs $400 to $800 in labor. The fixtures themselves are separate.

A partial remodel with a new tub or shower surround, new vanity, and updated supply lines typically runs $1,500 to $3,500 in plumbing labor, depending on the complexity of the drain and vent work.

A full bathroom gut-and-rebuild with a new layout — moving the toilet, adding a freestanding tub, installing a walk-in shower with a linear drain — typically runs $4,000 to $8,000 in plumbing labor alone. This includes rough-in, inspections, and finish connections.

What drives the price up: moving the toilet (requires relocating the drain and vent stack), adding a second sink (new supply and drain runs), installing a steam shower (dedicated water line and drain), and working in homes with old galvanized supply lines that need to be replaced before new fixtures can be connected.

Our advice: get the plumber involved at the design stage. We can tell you what's structurally possible, what will require a permit, and what the rough-in will cost before you commit to a layout. Call 313-427-4780 to schedule a consultation.
