Plumbing Questions Behind Your Remodel Plan

Each change in your plan affects the plumbing, and much of that work has to happen before drywall and tile cover the connections.

  • Moving a Sink or Vanity

    A sink on a new wall means its supply and drain connections move too.

  • Adding Another Sink

    A second or island sink needs supply and drain connections first.

  • Replacing a Shower Valve

    A new valve behind the wall has to go in before the tile covers it.

  • Installing New Fixtures

    Faucets, toilets, sinks, or a disposal checked, fitted, and connected.

The Plumbing Side of Your Remodel

Rough-In Plumbing Behind the Walls

During rough-in, we install or move the supply lines that bring water to your fixtures and the drain lines that carry it away. Stub-outs, the short pipe ends left for final connections, and the valves that control the supply are placed to suit the fixtures you chose. This happens before drywall and tile cover the connections, and final trim follows when the room is ready.

Final Trim and Fixture Installation

The same crew that did the rough-in returns to set and connect sinks, faucets, toilets, shower valve trim, and disposals. Kitchen sink installation includes the supply, drain, faucet, and disposal where one is included. We check each fixture fits the prepared plumbing, then show you how it works and where the shut-off valves are. We wear shoe covers and leave the room cleaner than we found it.

Working With Your Remodel Contractor

We handle the plumbing in your remodel: supply lines, drains, valves, and fixture connections. Your remodel contractor handles the broader project. If you already have a contractor, we work with them on access for rough-in and readiness for final fixtures. If you need one, we can bring one in and work under them for the plumbing portion.

What Affects the Cost of Remodel Plumbing?

Financing is available through Wisetack, and every job starts with a free on-site estimate.

  • Moving Connections. The distance supply and drain lines need to move affects the scope.
  • Fixture Count. Adding sinks, toilets, shower valves, or a disposal adds installation work.
  • Existing Piping. Worn supply lines or connections may need attention while the walls are open.
  • Fixture Supply. Whether you provide the fixtures or need us to supply them shapes what is included.

Planning a Remodel in the Treasure Valley

If you notice mineral buildup on faucets or showerheads in your Boise, Meridian, or Nampa home, a remodel is a useful time to discuss hard water, since deposits can affect cartridges, shower valves, and toilet parts in your new fixtures. While walls are open, we also assess the accessible supply piping and explain any recommended work separately from the fixture installation.

I had some work done back in March of 2026. John was great, knew what he was doing. Now that I've had my new single-basin sink, new disposal and a new reverse osmosis system up and running for months, I can say without question the work was high-quality. John wasn't afraid to answer questions by this curious customer, no matter how lame my questions may have been. Next plumbling work I need I will be hiring him again. Hire this guy and avoid getting "jobbed" by others.

Remodel Plumbing FAQs

What is rough-in plumbing in a bathroom remodel?

Bathroom rough-in plumbing is the supply piping, drain piping, and valves installed before the walls and finishes close them in. It establishes the connections for your sink, toilet, tub, or shower. Final trim comes later, when the room is ready for fixtures. We explain both stages during the on-site estimate.

Do you do the whole remodel, or just the plumbing?

We handle the plumbing portion of your kitchen or bathroom remodel. That includes rough-in work and final fixture installation. If you already have a remodel contractor, we work with them. If you need one, we can bring in a contractor and work under them for the plumbing scope.

Can you move a sink, toilet, or shower to a different spot?

Yes, we can move plumbing connections for a sink, toilet, or shower, subject to the layout and available access. The work depends on where supply and drain lines can run and what the new fixtures require. We review your proposed locations during the free on-site estimate and explain the plumbing involved.

Do I need the plumber before or after the tile goes in?

You need plumbing work before the tile for rough-in and afterward for final trim. Lines, concealed valves, and connection points need to be positioned while access is available. Once the surrounding finishes are ready, we return to install the fixtures and visible trim. Discussing fixture choices early helps us prepare the correct connections.

Can you install a faucet, toilet, or sink I bought myself?

Yes, we can install a faucet, toilet, or sink you purchased yourself. We review the fixture and its connection requirements to check how it fits the planned plumbing. Our one-year workmanship warranty covers our installation work, while the fixture itself carries any warranty provided by its manufacturer.
