Know the signs

Decide these before the walls close.

An open wall is the cheapest moment to fix what is behind it.

Moving a toilet

Drains need steady slope. A move is straightforward over a crawl space or basement and much harder over a slab.

A basement bathroom

Below the sewer line, waste has to be lifted by an ejector pump, which shapes the layout and the cost.

Old pipe in the wall

Replace aging galvanized supply lines, add shut-offs and upgrade the shower valve while the wall is open.

Your own fixtures

We install owner-supplied fixtures, and tell you if one looks likely to cause trouble later.

How it works

Plan. Rough in. Trim out.

Remodel plumbing happens in two visits, weeks apart, with other trades working in between.

Questions

Remodel plumbing, answered.

Answers from licensed plumbers. Still unsure? Call (509) 535-5946, 24 hours a day.

How long does remodel plumbing take?
Plumbing happens in two visits: rough-in once framing is done and before drywall, then trim-out after the finishes are in. Each usually takes one to a few days depending on scope, with weeks of other trades’ work in between.
Can I move a toilet or sink during a remodel?
Usually, but distance and direction matter. Drain lines need steady slope, so moving a toilet often means opening the floor and rerouting waste: straightforward over a crawl space or basement, much harder over a slab. Supply lines are far more flexible.
Do I need a permit for remodel plumbing?
Generally yes, for anything beyond a like-for-like fixture swap. Moving fixtures, adding a bathroom or changing waste and supply lines needs a permit and inspection, and we pull them; unpermitted plumbing tends to surface at resale.
Can you add a bathroom in my basement?
Often, yes. If the basement floor sits below the sewer line, waste has to be lifted by an ejector pump instead of flowing by gravity, which affects layout and cost, so we check the elevation before you finalize the design.
Should I buy my own fixtures?
You can, and we install owner-supplied fixtures. The caution is that inexpensive online fixtures often use hard-to-find parts, so a repair years later becomes a replacement; we will tell you honestly if one looks likely to cause problems.
