What Our Sink Installation Service Covers
We install kitchen, bathroom, and utility sinks in both residential and commercial settings. Each job is handled by our licensed, insured plumbers or one of our trusted partner companies. The work isn’t handed off to unfamiliar subcontractors.
A complete installation typically includes removing the existing fixture, properly sealing and leveling the new sink, connecting supply and drain lines, and testing for leaks before we leave. What that looks like in practice depends on the sink type:
Kitchen Sinks
We install undermount, drop-in, and farmhouse styles. Kitchen installations often include garbage disposal hookups and new water supply line connections.
Bathroom Sinks
Vanity, pedestal, and wall-mounted sinks all require careful drain assembly and shutoff valve connections. We handle each configuration.
Utility & Laundry Sinks
These sinks take heavier daily use, so fittings and connections are selected with that demand in mind.
Our connection to a broader contractor network also means we can take on large-scale commercial builds, such as multi-fixture installations, that require more equipment and coordination than a single plumbing crew can manage.
Why San Rafael Homeowners & Businesses Choose Marin H2O
Our work comes with a one-year labor warranty, and estimates are always free. We offer same-day and emergency appointments whenever our schedule allows, and financing options are available on select services.
We operate on straightforward values: integrity, accountability, respect, professionalism, transparency, and genuine customer service. Those aren’t marketing words for us. They’re the reason we’ve been doing this work in the same communities since 1961.
Sink Installation & Water Quality: A Natural Combination
Many Marin and Sonoma County homes, particularly older properties in San Rafael with galvanized pipes, have aging infrastructure that benefits from attention during any fixture update. We have direct experience with those conditions, and we bring that local knowledge to every installation.
Because we’re a water treatment company as well as a plumbing company, we can pair any sink installation with a free water analysis. When supply lines are already being accessed, it’s a practical time to add or upgrade an under-sink water filtration system. We install and service filtration products from Culligan, one of the most recognized names in the industry, so customers can address both the fixture and the water running through it in a single visit.
