A bathroom remodel is only as good as the plumbing hidden inside the walls and floor, and that's the part a homeowner never sees until it leaks. Bathroom remodel plumbing is the rough-in and finish work behind the tile — relocating supply, drain, and vent lines when fixtures move, setting the shower and tub valves at the right depth and height, and tying everything back to the stack correctly so traps don't siphon and the new layout drains the way it should. We coordinate with your builder or GC and stage the work around demolition, framing, and tile so the plumbing is right before anything closes up.
The plumbing decisions in a remodel are the ones that are expensive to change later. Moving a toilet means relocating a 3-inch drain and its vent, not just the supply; a freestanding tub needs a floor-mount or freestanding filler and a drain roughed to the exact tub spec; a curbless walk-in shower needs a linear or point drain set into a properly sloped and waterproofed base; and a double vanity needs the supply and drain split and vented for two sinks. We rough in all of it to code and pressure-test the supply before the walls go back across {city}.
Because it's inside walls and under floors, remodel plumbing is permitted and inspected, and we handle that end to end — pulling the permit, scheduling the rough-in inspection before cover, and the final inspection after the fixtures are set. Getting the rough-in dimensions right the first time is what keeps a {county} remodel on schedule; a valve set too deep for the finished wall or a drain an inch off spec means opening finished tile. We measure against your actual fixtures and finish thickness before we cut, so the trim and fixtures land clean across {areas}.
Signs you need bathroom plumbing
Moving the toilet, tub, or vanity
Relocating a fixture means moving its drain and vent, not just the supply line — the part that has to be right before framing closes. It's the core of a the United States remodel rough-in.
A tub-to-shower conversion changes the drain location and needs a sloped, waterproofed base and often a new valve. Roughing it correctly is what keeps a curbless the United States shower from leaking.
Adding a second sink or a freestanding tub
A double vanity needs split, vented supply and drain, and a freestanding tub needs its filler and drain roughed to spec. Both are set during the your area rough-in, before the finishes.
Outdated or failing bathroom plumbing
Old galvanized supply, a corroded shower valve, or an under-vented drain are best replaced while the walls are already open. A remodel is the ideal time to modernize the the United States plumbing behind the tile.
Upgrading shower fixtures or body sprays
Thermostatic valves, rain heads, and body jets need larger supply lines and correct valve rough-in. We size and set them so the new shower delivers the flow it's rated for.
Common causes & what we fix
Fixture relocation
Changing the bathroom layout moves toilets, tubs, and sinks off their existing drains and vents. New rough-in runs are the heart of a the United States remodel and have to be set before framing closes.
Design and layout upgrades
Curbless showers, freestanding tubs, and double vanities each carry specific plumbing requirements. Meeting them in the rough-in is what makes the finished the United States design work.
Code compliance and venting
Older bathrooms are often under-vented or lack anti-scald protection, which current code requires. A remodel brings the your area plumbing up to standard while the walls are open.
Accessibility conversions
Curbless showers, grab-bar blocking, and comfort-height fixtures make a bathroom accessible and change the plumbing layout. We rough them in as part of the the United States remodel.
Replacing aged plumbing
Galvanized supply, corroded valves, and cast-iron drains reaching end of life are best swapped during a remodel. Doing it now avoids opening finished tile later in the the United States home.

Frequently asked about bathroom plumbing
Top questions homeowners searching for Bathroom Plumbing near me ask us:
Do you work with my contractor or designer?
Yes — we coordinate directly with your GC, designer, or tile setter and stage our rough-in and finish work around demolition, framing, and tile. Getting the sequence right is what keeps a the United States remodel on schedule.
Can you move the toilet or tub to a new spot?
Yes — relocating a fixture means running new supply, drain, and vent lines to the new position and tying back to the stack correctly. We rough it in to code and pressure-test before the walls close across the United States.
Do you handle the permit and inspection?
Yes — bathroom remodel plumbing is permitted work, so we pull the permit, schedule the rough-in inspection before cover, and the final inspection after fixtures are set. It's built into the your area project scope.
How is a remodel plumbing job priced?
As a scoped quote rather than a flat rate, because the work depends on how many fixtures move and how much line has to be rerun. We assess the the United States plan, scope the rough-in and finish work, and give you a written estimate.
When in the remodel do you come out?
Twice at least — once for the rough-in after demolition and framing, before insulation and tile, and again to set the fixtures after the finishes. We schedule around your other trades and serve ZIPs across the United States.
