Bathroom sink installation involves more than dropping a basin into a countertop. The drain has to be correctly sized and positioned, the P-trap has to have proper slope to drain without holding water, and the supply connections need to be secure without being overtightened. Each sink style presents its own set of considerations, and getting those details right is what keeps the installation from becoming a slow leak problem later.
Whether you're replacing a single sink or installing new ones as part of a larger Bathroom Remodeling, coordinating the drain rough-in with your vanity or countertop installer early avoids a mismatch that's expensive to fix once the counter is already set in place.












Sink Styles We Install
Undermount Sinks
Mounted below the countertop surface, undermount sinks require the drain to be positioned precisely before the countertop is set. We coordinate with your countertop installer on drain location and handle the supply and drain connections once the counter is in place.
Vessel Sinks
Vessel sinks sit on top of the counter and require a taller drain assembly and a faucet with enough height to clear the basin. We verify the drain rough-in height and faucet compatibility before installation begins.
Pedestal Sinks
A pedestal sink has no cabinet to conceal the supply lines and P-trap, which means the connections need to look clean as well as function correctly. We set the pedestal level, secure the basin, and dress the supply and drain connections neatly.
Drop-In Sinks
The most straightforward installation type, drop-in sinks rest in a cut countertop opening with a rim that overlaps the surface. Connections are made from below and are accessible through the vanity cabinet.
Most Sink Replacements Include a New Faucet
A sink replacement is also the easiest time to update the faucet, since both are already disconnected and the countertop or vanity is already exposed. If your current faucet doesn't match the new sink's mounting configuration, hole count, or finish, the Faucet Installation is best handled in the same visit rather than coming back for it later. We coordinate the sink and faucet together whenever both are part of the project, so the hole spacing and connections line up the first time.

Our Sink Installation Process
Confirm Drain Position
We start by confirming the drain location is correctly positioned for the sink style being installed.
Rough In or Remove the Old Sink
For new installations, we rough in the supply and drain before the vanity or countertop goes in. For replacements, we disconnect and remove the existing sink, inspecting the supply valves and drain for condition.
Replace Worn Components
Any valves or drain components that have corroded or are showing wear get replaced before the new sink goes in.
Set, Connect & Test
We connect the supply lines, install the P-trap with correct slope and clearance, secure pedestal sinks to the floor and wall at the correct height, and test all connections before finishing.

Sink Installation Cost in Okemos, MI
A straightforward drop-in or undermount replacement is one of the more affordable bathroom plumbing services we offer. Vessel and pedestal installations with custom supply line positioning or rough-in modifications take more time. Coordinated installations as part of a larger renovation are priced within the broader project scope.
Why Choose Plumbing by Custom Built
Sink installation done well is something you do not notice, everything drains, nothing leaks, and the connections look clean. Done poorly, it shows up as a slow drip under the cabinet or a trap that was never sloped correctly, the kind of problem that's easy to miss until it has already caused real damage underneath.

FAQs
How long does bathroom sink installation take in Okemos, MI?
A standard drop-in or undermount replacement typically takes one to two hours. Vessel and pedestal installations with rough-in modifications may take longer.
Can I install a vessel sink over an existing vanity in Okemos?
In most cases, yes, provided the existing drain rough-in height is compatible with the vessel drain assembly. We assess this before installation to confirm it will work without modifications.
Do I need new supply valves when replacing a sink in Okemos, MI?
Not always, but we inspect the existing shut-off valves as part of the installation. Valves that have not been operated in years are often corroded or seized and worth replacing while the supply is already disconnected.
What is a P-trap and why does it matter for a bathroom sink in Okemos?
The P-trap is the curved section of drain pipe below the sink that holds a small amount of water to block sewer gases from entering the bathroom.
What's the difference between a single-hole and a widespread faucet, and does it affect sink installation in Okemos?
A single-hole faucet mounts through one hole in the sink or countertop and combines the handle and spout in one unit. A widespread faucet has separate hot, cold, and spout components set into three separate holes, which requires the sink or counter to already have the correct hole spacing cut. If you're changing from one style to the other, that's worth confirming before the new sink or faucet is ordered, since it can determine which sink or counter configuration you need.
