Plumbing for Kitchen & Bath Remodels
Plumbing Work in Kitchen and Bathroom Remodels
Every kitchen and bathroom remodel runs through the plumbing. Where the sink sits, whether the shower moves, how a new island gets its drain — those are plumbing questions before they are design questions. At Gatica’s Construction and Remodeling, that work is part of the remodel itself, done by our own licensed crew under a single contract that also covers electrical, tile, waterproofing and general construction.
Because the same team handles the rough-in and the finish work, fixture placement follows your design instead of whatever the existing pipes happen to allow.
Plumbing Work a Kitchen Remodel Can Involve
- Sink and Faucet Installation — Set and connected to suit your new layout
- Supply and Drain Rerouting — Moving lines for an island, a peninsula or a relocated sink
- Dishwasher and Refrigerator Lines — Water supply and drain connections for new appliances
- Garbage Disposal — Installed or replaced as part of the sink assembly
- Gas Line Work — Safe connections for ranges, cooktops and fuel conversions
- Pot Fillers and Instant Hot Water — Rough-in and installation where the design calls for them
- Water Filtration — Under-sink and whole-home systems fitted during construction
- Shutoff Valves and Supply Lines — Replaced before new cabinetry closes them in
Plumbing Work a Bathroom Remodel Can Involve
- Shower and Tub Valves — Installed for new enclosures and walk-in shower conversions
- Shower Pans and Drains — Assembled and tied into the waterproofing before tile goes on
- Toilet Relocation and Replacement — Including flange and drain adjustments for a new layout
- Vanity Sinks and Faucets — Single and double vanity installations
- Drain Rerouting — New fixture placement without designing around the old footprint
- Supply Line Replacement — Aging lines swapped out while the walls are open
- Accessibility Fixtures — Curbless showers, handheld units and grab bar blocking
- Ventilation Coordination — Exhaust routed around the new fixture and duct layout

Frequently Asked Questions About Remodeling Plumbing in the Bay Area
Q: Do you handle the plumbing yourselves, or is it subcontracted?
A: We handle it. Plumbing, electrical, tile and waterproofing are performed by our own licensed crew as part of the remodel, under one contract with one point of contact.
Q: Can you move a sink, shower or toilet to a new location?
A: In most cases, yes. Relocating a fixture means rerouting supply and drain lines, which we plan during the design stage so the new layout works structurally and meets code.
Q: Does a kitchen or bathroom remodel need a plumbing permit?
A: Usually, once lines are moved, added or replaced. We pull the permits and carry the project through final inspection as part of the job, so nothing is left for you to close out.
Q: Will the plumbing work add time to my remodel?
A: Rough-in and fixture setting are built into the project schedule rather than added on top of it. Kitchens typically run 6 to 12 weeks and bathrooms 2 to 4 weeks, depending on scope.
Q: What happens if you find old galvanized or cast iron pipes?
A: It comes up often in older Bay Area homes. Once the walls are open we show you exactly what is there and walk through the options before any additional work goes ahead.
Q: How much does the plumbing portion of a remodel cost?
A: Costs vary depending on scope, materials, and layout. We provide a detailed written estimate after a free in-home consultation — no obligation.
