Kitchen and bathroom remodel plumbing
What goes in behind drywall decides how the rest of the remodel turns out. Rough-in, fixture install, drain rework, and clean tie-ins, handled from walk-through through final inspection.
What the work involves.
Remodel plumbing is where the wrong line in the wall costs twice as much to fix once the drywall is up. Seth has been roughing in kitchens and baths since 2016, on everything from a single-room fixture swap to a full gut. The job lives or dies on what gets done before the walls close, and that’s where we spend most of our time.
We work direct with homeowners on smaller remodels and alongside general contractors on the bigger ones. Either way, the plumbing schedule is ours to coordinate. Rough-in inspection, trim-out timing, and tie-ins to the existing supply and waste are on us. Your GC doesn’t have to babysit the plumbing schedule, and you don’t have to be the messenger between us and the rest of the trades.
Every job starts with a walk-through and a real look at the plan. We size for the fixtures you’re putting in, not the ones the previous owner picked twenty years ago. If we see something that’s going to cause trouble (galvanized supply, undersized vents, a layout that fights the existing waste stack), we tell you straight before any demo starts. If something does come up once the work starts, you hear about it before we touch it.
What we handle.
The jobs we handle most often. If yours isn’t on the list, give us a call and ask.
Rough-in and drain rework
Supply lines, drain stacks, vents, and shower valves laid in before the walls close. We size for the fixtures you’re putting in, not what was there before.
Fixture install and trim-out
Toilets, vanities, kitchen sinks, free-standing tubs, shower systems, pot fillers, and pull-down faucets. Clean caulk lines, level set, and no leaks at the trap when we walk away.
Tie-ins to existing supply and waste
New work joined to the old house without surprises. We check for galvanized pipe, undersized vents, and the other things that show up mid-remodel before they become a problem.
Permit coordination and inspections
We pull plumbing permits when the job needs them and stay on site for the rough-in and final inspections. Your GC doesn’t have to babysit the plumbing schedule.
Shower valve and pan installs
Pressure-balance valves set to the right depth, shower pans sloped to drain, and curbless installs where the homeowner wants a tile-flush threshold.
Toilet relocation and supply re-routes
Moving the toilet to where the new design wants it, with the drain in the right spot and the supply tied in cleanly. Slab or crawlspace, we handle the route.
Kitchen sink and disposal hookups
Undermount, farmhouse, or drop-in sinks. Disposal sized to the cabinet, drain tied to the trap, and the dishwasher discharge looped properly.
Galvanized pipe replacement
When demo uncovers old galvanized supply, we replace it with copper or PEX before the walls close. Better water pressure, no rust in the lines, and a system built to hold up over time.
Fixtures we install.
Everything that hangs on the wall, drops in the floor, or mounts to the counter at the end of a remodel.
Toilets
Standard gravity-flush, dual-flush, comfort-height, and wall-hung toilets. Set on a fresh wax ring with a proper supply stop and a sealed flange.
Bathroom vanities and sinks
Single, double, vessel, undermount. We coordinate the P-trap, drain rough, and supply rough to fit whatever cabinetry the design calls for.
Free-standing and drop-in tubs
Setting and connecting free-standing tubs with floor-mounted faucets. Drop-in installs with the right supply and overflow connections.
Shower systems
Single-handle, thermostatic, multi-head, and rain showers. Valve set plumb, pressure tested, working hot and cold before the tile goes up.
Kitchen sinks
Stainless undermount, granite composite, fireclay farmhouse. We rough the drain to fit the cabinet and the sink basin you picked.
Kitchen faucets and pot fillers
Pull-down, pull-out, side-spray, and wall-mounted pot fillers. Hot and cold tied in, leak-checked, and torqued to the manufacturer spec.
Garbage disposals
Continuous-feed disposals sized to the sink and the household. Tied to the trap and to the dishwasher discharge with the air gap or high loop the code calls for.
Bidets and bidet seats
Adding a bidet seat or installing a dedicated bidet fixture. Hot-and-cold supply where the unit needs it, drain tied in cleanly.
How we do the work.
Copper supply lines
Type L copper for exposed runs and any spot where flexible tubing isn’t the right answer. Sweat-soldered or pressed where access is tight.
PEX-A and PEX-B
Flexible water supply for runs through walls, ceilings, and floors. Expansion fittings on PEX-A, crimp rings on PEX-B. Manifold layouts where the design supports it.
PVC drain and vent
Schedule 40 DWV pipe for waste lines and vent stacks. Sized for the fixture count and routed for proper slope, with cleanouts at the right access points.
Pressure-balance shower valves
Anti-scald valves are required by current code for new shower installs. We set valve depth to match the finished wall thickness so the trim plate sits flush against the tile.
Brass shutoff valves
Quarter-turn brass stops at every fixture. Easy to service, no failed plastic stops in five years, and an obvious shutoff if a supply line ever fails.
Curbless shower drain assemblies
Linear drains and offset assemblies for curbless showers. We slope the pan to the drain so the water goes where it should, not across the bathroom floor.
When to give us a call.
If any of these match what you’re planning, call us before the design is locked. Getting plumbing eyes on the layout early keeps the budget tight and the timeline honest.
- You’re planning a kitchen or bath remodel and the existing layout is changing
- A contractor told you the plumbing in the wall is undersized or galvanized
- You want a free-standing tub or a curbless shower and aren’t sure if the drain can be moved
- You’re adding an island sink, pot filler, or laundry to a spot that didn’t have one
- The shower in the existing layout doesn’t drain right and the remodel is the chance to fix it
- Demo uncovered old galvanized supply lines that need to be replaced before the walls close
- The bathroom is moving (or doubling) and the venting needs to be re-thought
- Your GC needs a licensed plumber on the rough-in schedule and you don’t have one yet
