Faucet & Disposal Integration in O'Fallon, MO
Often, a new sink installation goes hand-in-hand with a new faucet and garbage disposal. We carefully integrate these components, ensuring all connections are compatible and functioning correctly.

This combined service saves you time and ensures all parts work together smoothly in your O'Fallon, MO home.

Undermount Sink Installation in O'Fallon
Undermount sinks offer a sleek look and are popular for their low-maintenance design. Their installation requires precise cutting of countertops and secure mounting from underneath. Our plumbers are experts in creating watertight seals and using the right clips and adhesives to ensure the sink is firmly in place, preventing future sagging or leaks that can damage cabinets and subfloors over time.
Double Vanity Sink Installation in O'Fallon
Adding a second sink means adding a second drain and two more supply lines. We extend the drain with a properly sized fitting, install new stops, and make sure both bowls drain freely without siphoning each other's traps. When the wall needs to be opened, we tell you up front. A double vanity is one of the most requested upgrades in primary bathrooms.

A new sink installation often includes new faucets and drain assemblies. We carefully install all components, from single-handle to widespread faucets, and ensure proper P-trap and drain connections. We work with all major brands like Moen, Delta, Kohler, and Pfister, confirming compatibility and efficient water flow. Our attention to detail prevents common post-installation issues like slow drains or drips.
Utility Sink Installation in O'Fallon
Utility sinks in laundry rooms, garages, or workshops need to be sturdy and correctly installed to handle heavy use. FGV Plumbing installs durable utility sinks, ensuring strong support for the basin and proper drainage for large volumes of water. Homes around O'Fallon on private wells should test for hardness and bacteria before picking a treatment system. We plan for that with solid connections and P-traps that can be easily maintained.
Leak-Proof Sink Connections in O'Fallon, MO
The most important part of any sink installation is making sure all connections are leak-proof. Our plumbers use high-quality sealants, proper pipe dope, and correct torque on all fittings to prevent drips and leaks. We run thorough water pressure tests after every installation to confirm watertight integrity. This attention to detail protects your cabinets and floors and extends the life of your new sink in O'Fallon, MO.

Wall-Mount and ADA Sink Installation in O'Fallon, MO
Wall-hung sinks need carriers or heavy blocking to meet load requirements. For accessible bathrooms, we set the rim height and knee clearance to ADA guidelines and insulate or shield exposed pipes under the basin. This is common in aging-in-place remodels and small commercial restrooms. We make sure the sink is strong enough to lean on safely.

Frequently Asked Questions About Sink Installation in O'Fallon
The cost for sink installation in O'Fallon, MO typically ranges from $200 to $600 for labor alone, depending on the sink type (for example, drop-in vs. undermount), complexity, and if any modifications to existing plumbing or countertops are needed. This does not include the cost of the sink itself. We provide a written, upfront quote after an on-site assessment.
A basic drop-in swap is doable for experienced DIYers. Undermount, vessel and wall-hung sinks involve support, sealing and drain height details that are easy to get wrong.
Most bathroom sink installs take two to four hours. Undermount sinks may need adhesive cure time before the drain is fully loaded.
You can either purchase the sink yourself, or we can help you with selecting and sourcing one from our trusted suppliers. Many customers prefer to choose their own sink to match their style, but we are happy to recommend durable, high-quality options suitable for O'Fallon homes.
Common signs you might need a new sink include persistent leaks around the basin or drain, cracks or chips in the material, severe staining that won't clean, rust, or if you're simply upgrading for style or function. An old, damaged sink can also lead to water damage in your vanity.
Generally, simply replacing an existing sink with a new one of the same type does not need a permit in Missouri. However, if the installation involves altering the drain or water supply lines, or changing the location of the sink, a plumbing permit may be required. FGV Plumbing can explain local code requirements for your specific project.
Absolutely. If your new sink is compatible, we can easily install a new garbage disposal unit as part of the installation process. We provide proper electrical connections, secure mounting, and correct drainage, making sure your kitchen plumbing is fully functional.
A straight replacement typically does not need a permit. Adding a new sink or moving drain lines may require one, depending on your local jurisdiction, and we will let you know.
