What it is
Bathroom remodel plumbing Bathroom remodel plumbing is the work of relocating, replacing, or upgrading the water supply lines, drain lines, and fixtures inside a bathroom as part of a renovation project.
Denver's building permits require licensed plumbing work on any relocated drain or supply line, so a remodel that skips proper permitting can create problems at resale.
Drain slope and venting decide what layout is possible
Supply lines are flexible. Drains are not. Every fixture needs fall to the stack and a vent within its trap arm distance. In older Denver homes with cast iron stacks and joists running the wrong way, that is what determines whether a layout works.
- Fixture relocation planned around joist direction and stack location
- Curbless and linear drain showers where the framing allows
- Old galvanized supply replaced while walls are open
- Shutoffs, stops, and access panels placed for future service
Bring a plumber in early when
- You are moving the toilet, tub, or shower drain
- You want a curbless or linear drain shower
- The house still has galvanized supply or cast iron drains
- You are converting a tub to a shower or adding a second sink
- The bathroom is over a finished ceiling
