Stinson Plumbing
Plumbing Rough-Ins for New Homes in Western Kentucky
From slab groundwork to fixture trim-out, Stinson Plumbing handles every phase of new construction plumbing.
Building a new home means getting the plumbing right the first time. Once concrete is poured over supply and drain lines, a mistake is buried, literally, and fixing it later means breaking up the slab you just paid for. We rough in homes across Marshall, Graves and McCracken counties, and the work is built to pass inspection and last the life of the house.
New construction plumbing is less about repair and more about planning. The lines you set before the slab decide where every fixture lands for the next thirty years. Get the layout, the slope and the sizing right and the system runs quiet and trouble-free. Rush it and the problems show up after the homeowner has moved in, when they are hardest to reach. We treat the rough-in as the foundation it is.
What new construction plumbing includes
Underground rough-in, before the slab pour
Sewer mains, water supply entry points and under-slab drains get placed here. We set stub-ups for every toilet, shower, tub and floor drain, and we check the slope on every drain line so waste flows the way it should. These locations have to match the floor plan exactly, because moving them after the pour means jackhammering concrete. We measure against the plan twice before anything gets set.
Top-out rough-in, after framing
Supply lines, drain-waste-vent stacks and gas piping run through wall cavities and floor joists. We coordinate with your HVAC and electrical subs so nothing conflicts and no line ends up where a duct or a stud has to be. All work is pressure-tested and ready for inspection before drywall goes up, so nothing gets closed in until it has passed.
Fixture trim-out, after paint
Faucets, toilets, disposals, dishwasher connections, water heaters and outdoor hose bibs. We install everything, test flow and check for leaks before the final walk-through, so the homeowner takes the keys to a system that works on day one rather than a punch list.
What a full rough-in package covers
When we price a build, the package is the whole plumbing scope from the ground up, not a list of parts. A typical new-home rough-in includes:
- Under-slab sewer and drain lines with proper slope and cleanouts
- Water service entry and main distribution sized to the home
- Drain-waste-vent stacks vented to the roof
- Supply runs to every fixture, with shutoffs where they belong
- Gas line rough-in for the appliances you plan to run
- Tub and shower valves set before the walls close in
- Water heater connection and venting
- Hose bibs, floor drains and any outdoor connections
- Full trim-out of fixtures, plus pressure tests and a leak check
Send us the floor plan and we will scope all of it so there are no surprise line items halfway through the build.
Sewer and septic connection
Every new home has to send waste somewhere, whether that is a municipal sewer tap or a private septic system. We make the connection from the house to the main or the tank and set it with the slope and cleanouts that keep it flowing for the long haul. On rural lots running a septic system, we coordinate the building drain to the tank so the septic and sewer side is right from the start. Getting this wrong is one of the most expensive things to fix later, so it gets done carefully the first time.
Gas line rough-ins
Most new builds in our area run natural gas or propane. We rough in gas lines for water heaters, ranges, gas dryers, fireplaces, standby generators and future outdoor kitchen connections. Every gas line is pressure-tested and leak-checked per Kentucky code. If you are not sure yet whether you want a gas range or an outdoor kitchen down the road, we can stub for it now, which is far cheaper than opening a finished wall later.
Materials that hold up
The pipe behind the wall matters as much as the fixtures in front of it. We run materials suited to the job and to western Kentucky conditions, and we size supply lines so every fixture gets the flow it needs even when more than one runs at once. A house where the shower drops cold the moment someone starts the dishwasher was undersized at the rough-in, and that is the kind of thing we plan out before it gets built in rather than explain away afterward.
Inspections and code
New construction answers to code at every stage, and the inspections come in order: underground before the pour, top-out before drywall, final at trim. We build to pass the first time, schedule the required inspections and stay on top of the timeline so a plumbing hold does not stall the whole build. When something has to be done a certain way to meet code, we do it that way and tell you why rather than cutting a corner that fails later.
Our work
Recent construction work
Working with your general contractor
We work alongside GCs in Benton, Mayfield, Owensboro and Paducah. We show up when we are supposed to and get out of the way so the next trade can start, because a build runs on everyone hitting their window. We also handle multi-family builds and small commercial projects, and we keep our part of the schedule clear so you are not waiting on plumbing to move the job forward.
Well water and rural builds
Building outside city water limits? Many rural lots in Marshall and Graves County rely on private wells. We install pressure tanks, well line connections, whole-home filtration and softeners as part of the rough-in. Well water often carries iron, hardness or sediment, so planning the treatment into the build means clean water from the first day instead of a retrofit after the homeowner notices the staining. We also set the water service line from the source to the house so it is sized and buried right.
Lake-area and second homes
Western Kentucky has a lot of lake property, and those builds come with their own questions, from seasonal use to longer service runs. A home that sits empty part of the year needs to be set up so the plumbing handles the down time without trouble. We plan the rough-in around how the home will actually be used, not just a standard template, and we talk through shutoff placement and freeze protection so a home left over the winter is not a callback in the spring.
One plumber from groundwork to keys
When the same crew handles the underground, the top-out and the trim, nothing falls through the cracks between phases. The plumber who set the stub-ups is the one connecting the fixtures, so the stub that looked fine at the pour is the stub that gets verified at trim. That continuity is where rough-in quality really comes from. It is also worth thinking past the fixtures while the walls are open, since adding a stub for a future bathroom, a water softener loop or an outdoor kitchen costs little now and a great deal once everything is closed in. We will walk the plan with you and flag the cheap-now choices that save real money later.
Good to know
New Construction Plumbing Questions
Do you pull the plumbing permits?
Yes. We handle the permit application and schedule the required inspections at each stage of the build.
Can I supply my own fixtures?
You can. Just make sure they arrive on site before our trim-out date. We install all major brands.
How long does the rough-in take?
A standard two-bathroom home takes two to three days underground and another two to three for top-out. Trim-out is usually one day. Inspections between stages can shift the calendar, so we plan around them.
Do you rough in radiant heat?
Yes. We install hydronic radiant floor systems during the rough-in phase, before the slab pour or under the subfloor in framed construction.
Can you set up plumbing for a well instead of city water?
Yes. We install pressure tanks, well line connections and whole-home filtration or softeners as part of the rough-in, so a rural build gets clean, steady water from the start.
