Plumbing installation in Kuna, ID covers the planned jobs that put water where you want it: a new bathroom sink, a shower or tub, a washer hookup, a kitchen remodel or a house that has pipes roughed in but no fixtures connected. Kuna Express Plumbing answers the line 24/7, and installs are booked for a day that fits your project.
Licensed plumbers do the work, tell you the price before they start and explain what the code asks for. If a fixture has simply worn out, our faucet repair and toilet repair pages may be the better fit.
Fixtures and appliances we install
- Bathroom and kitchen sinks, faucets, and the drain and trap beneath them.
- Showers, tubs and shower valves, including a replacement of an old trim kit.
- Toilets, with the old unit removed and a new wax ring or flange connection.
- Washing machine hookups with supply valves and a standpipe.
- Dishwasher and ice maker supply and drain connections.
- Utility sinks, outdoor hose bibs and laundry room plumbing.
Garbage disposals have their own page, so see garbage disposal repair for that work. Water heaters are covered on the water heater installation page.
Hooking up a house that has no plumbing yet
Some calls come from owners who bought a shell, finished a garage into a living space or built an outbuilding with nothing connected. That is a different job from swapping a faucet. The plumber has to find where the water, drain and vent will tie in, size the lines, and make sure the drain slopes and the fixtures are vented.
Tell dispatch whether the walls and floor are open and whether a rough-in has been done. The answer decides whether this is a one-visit hookup or a staged job with an inspection between steps.
Shutoffs and why every fixture should have one
A fixture without its own shutoff turns a small repair into a house-wide water outage. We install or replace stop valves at sinks, toilets and appliances so you can isolate a single fixture without touching the main. Old valves that no longer close, or that weep at the stem, are replaced during the install because they are the next likely leak.
Know where your main water shutoff is before any project starts. If a job goes wrong and water will not stop, close the main and call. Our burst pipe repair page covers active leaks.

Remodels, additions and new construction
| Project | What the plumbing usually involves | Plan ahead for |
|---|---|---|
| Bathroom remodel | Moving or replacing fixtures, valves and drains | Wall access, rough-in timing, inspection |
| Kitchen remodel | Sink, dishwasher, faucet and supply changes | Cabinet and countertop schedule |
| Basement or garage conversion | New supply, drain and vent runs | Drain slope and how it ties in |
| Laundry room addition | Washer supply, standpipe and drain | Venting and shutoff placement |
| New home or addition | Full rough-in and trim-out | Permit, inspection stages, builder schedule |
General contractors and builders who need a plumbing subcontractor can call and describe the project. We tell you what we can bid and what needs more information. Remodels are best booked early, because the plumber needs to be on site before walls close.
Why a Kuna home may be hiding older or newer pipes
Kuna grew from 15,210 people in 2010 to 24,011 in the 2020 census, with 7,948 housing units counted in 2020. For you, that mix means a block can hold houses of very different ages with different piping behind the walls. A plumber opens the access, sees what material is there and plans the connection to match. We do not assume what your pipes are made of.
If the existing lines are in poor shape, a new fixture is a good moment to look at the bigger picture, and our repiping page explains when whole-house work makes sense.
Before the plumber arrives
Clear the work area, measure the space for the fixture, and have the fixture or appliance on site if you bought it yourself. Know where your main shutoff is. If a fixture is already connected, photograph the existing supply and drain so the plumber can see what is behind the cabinet or wall.
Permits and who may pull one
The City of Kuna issues plumbing permits through its Building Department, and the January 2025 application lists new dwellings, plumbing for existing residences and detached shops, water lines, sewer lines and backflow devices among covered work. Not every small job is treated the same, so ask the Building Department at (208) 922-5546 or Permits@KunaID.gov before you start.
Per the City form, work without a permit costs double the permit fee as the minimum charge. DOPL says homeowners may buy a permit only for their own primary or secondary residence and outbuildings. Multi-family permits in Kuna are for contractors only. The adopted code is the 2017 Idaho State Plumbing Code.
A note on sump and ejector pumps
Sump and ejector pump calls come in rarely, and they are different from fixture work. A pump that serves a basement or a below-grade bathroom needs the right discharge path, a check valve and an outlet that is safe for the location. Whether your home has one at all, a plumber confirms on site.
Tell dispatch what the pump serves and what it is doing. If water is standing near outlets, stay out and shut off power only if you can reach the panel safely and dry.
