Rough-in plumbing is all the pipe work that happens before the walls get closed up. It's the supply lines that bring water to your fixtures, the drain lines that take waste away, and the vents that keep everything flowing properly. Once the rough-in is done and inspected, then drywall goes up, fixtures get installed, and you've got a working bathroom or kitchen. But if the rough-in isn't done right, you're tearing open walls later to fix it.

We handle rough-ins for bathrooms, kitchens, laundry rooms, and wet bars all over Lake Saint Louis, Wentzville, O'Fallon, and St Peters. Most of our rough-in work is for basement finishes where families are adding a bathroom or full kitchen downstairs. We also do rough-ins for additions, garage conversions, and new construction. The key is getting everything in the right place before drywall. That means running supply lines to where the sink, toilet, shower, and any other fixtures are going. It means getting drain lines sized correctly and sloped right so waste flows properly. And it means venting everything to code so drains don't gurgle or back up. We've done hundreds of rough-ins across St Charles County and we know exactly what needs done to pass inspection.

We Pass Inspection the First Time Every Time

Jim's a licensed master plumber in St Charles County, St Louis County, and the City of St Louis. We've been pulling permits and passing rough-in inspections since 1999. We know exactly what the inspectors expect — proper pipe sizing, correct drain slopes, right vent placement, proper support and hangers. Our work passes the first time because we follow code and we don't cut corners. Failed inspections delay your project and cost you money. We've done hundreds of rough-ins across Lake Saint Louis, Wentzville, O'Fallon, St Peters, and beyond, and we've built a reputation on getting it right.

We Work Around Your Contractor's Schedule

Rough-in plumbing is one piece of a bigger project. Your contractor has framers, electricians, HVAC guys, and everyone else lined up. If we're late or we cause delays, it throws everything off. We coordinate with your contractor so we show up when they need us and we get the work done on time. Most rough-ins take one to three days. We'll tell you upfront how long it'll take and we stick to the timeline. Once we're done, we schedule the inspection so your contractor can keep moving.

26 Years of Rough-In Experience

We've been doing rough-in plumbing since 1999. That's over two decades of bathroom rough-ins, kitchen rough-ins, basement finishes, additions, and new construction. We've worked in old homes where we're tying into outdated systems. We've worked in new builds where everything's starting from scratch. We know how to deal with concrete floors, tight spaces, tricky layouts, and all the challenges that come up during rough-in work. Experience matters when you're installing plumbing that's going to be buried in walls for the next 50 years.

Our Simple 3-STEP Bathroom and Kitchen Rough-In Plumbing PROCESS

1

We Review the Plans and Coordinate with Your Contractor

When you call (314) 807-8460, we'll ask about your project — what you're building, where fixtures are going, what your timeline looks like. We'll look at the plans if you've got them, or we'll come walk the site with you and your contractor. We'll tell you what needs done for the rough-in and when we can fit it into your contractor's schedule. We give you a price upfront so there's no surprises.

We Install the Rough-In Plumbing to Code

We run supply lines to where the fixtures will be — hot and cold water to sinks, toilets, showers, tubs. We install drain lines sized correctly for each fixture and sloped properly so waste flows. We install vents that tie into the main stack or vent out through the roof. Everything gets supported and secured properly. Most rough-ins take one to three days depending on the scope. Once we're done, we schedule the inspection.

3

We Pass Inspection and Your Project Keeps Moving

The inspector comes, looks at our work, and signs off. Our rough-ins pass the first time because we install to code. Once the inspection passes, your contractor can close up the walls and keep going. We'll come back later to install fixtures once everything's finished. Most fixture installs happen after tile, paint, and final finishes are done.

Frequently Asked Questions

Got Questions? We’ve Got Answers!

How long does a bathroom rough-in take?

A single bathroom rough-in usually takes one to two days depending on the layout and what fixtures you're installing. If it's a simple half-bath with a toilet and sink, it might take one day. If it's a full bathroom with a toilet, sink, tub, and separate shower, it'll take closer to two days. We'll tell you upfront what to expect.

How much does rough-in plumbing cost?

It depends on what you're doing. A bathroom rough-in usually runs $800–$2,000 depending on how many fixtures and how complicated the layout is. A kitchen rough-in runs $1,000–$2,500. If you're doing both a kitchen and bathroom for a basement finish, expect $2,000–$4,000 for the rough-in. We give free estimates so you'll know the price before we start.

Do I need a permit for rough-in plumbing?

Yes. Rough-in work requires a permit and inspection in St Charles County, St Louis County, and the City of St Louis. We pull the permit, we do the work, we schedule the inspection, and we make sure it passes. You don't have to deal with any of that — we handle it.

Can you work with my contractor's schedule?

Yes. We coordinate with your contractor so we show up when they need us. Rough-in work has to happen after framing but before drywall, so timing matters. We'll fit into your contractor's schedule and we'll be there when we say we will. Most contractors we work with call us back for future projects because we don't cause delays.

What if my basement has a concrete floor?

We break through the concrete to run drain lines where they need to go. Most basement bathrooms require breaking concrete because the drains have to slope down and tie into the main sewer line. We have the equipment to cut concrete, dig the trenches, install the pipes, and patch the concrete when we're done. It's all part of a basement bathroom rough-in.
