American Standard Serin Single Hole Single-Handle Bathroom Faucet 1.2 gpm/4.5 L/min With Lever Handle - AMS-2064131

Yes, with the optional escutcheon. The Serin 2064131 is a single hole, single handle faucet, but it mounts on 4 inch centers using escutcheon 2064.101P to cover the outer two holes. Without that plate it installs single hole only, so order the escutcheon at the same time if the lavatory or countertop is drilled three holes.

The drain is included. The Serin ships with American Standard's Speed Connect metal drain, which has fewer parts than a conventional pop-up assembly and goes in faster. Supply hoses are included too: braided flexible stainless steel with 3/8 inch compression connectors, 20 inches (508 mm) long. So for a straight replacement you need stops and the faucet, not a separate drain kit.

Yes. The Serin is lead free as defined by weighted average: total lead content is 0.25 percent or less by weighted average across the wetted surfaces. That is the threshold written into US potable water plumbing requirements, so it can go into occupied commercial, multi-family, and healthcare lavatories. The body is brass.

The Serin comes with braided flexible supply hoses terminating in 3/8 inch compression connectors, which is the standard US lavatory stop outlet, so they thread straight onto typical 3/8 inch compression angle stops with no adapters. The flexible stainless cable run is 20 inches (508 mm), which is what makes it workable in a tight vanity cabinet.

1.2 gpm (4.5 L/min) is the maximum flow rate on the Serin, and it is the common water conserving lavatory rate. For handwashing at a private or public lavatory that is plenty, and it is what most green building and water conservation programs ask for on a lav faucet. If you are filling buckets or need a kitchen or utility rate of flow, a bathroom faucet is the wrong fitting to start with.

Two finishes. Polished chrome is model number 2064131.002 and satin or brushed nickel PVD is 2064131.295. The PVD nickel is a physical vapor deposition coating, which is the harder of the two to scuff, and chrome is the one that matches most existing commercial washroom trim. If you are standardizing a building, order by that three digit suffix so every unit matches.

A single lever like the Serin sets temperature and volume in one motion, which is easier for wet or gloved hands and easier for anyone with limited grip, and it needs only one hole in the deck. A two handle widespread gives independent hot and cold trim and spreads across a three hole deck, which suits a larger vanity and a more traditional look. If your deck is already drilled three holes on 4 inch centers you can still use the Serin with escutcheon 2064.101P rather than replacing the sink.

Ceramic disc. The Serin uses a ceramic disc valve cartridge, which is what keeps a single lever from developing a drip the way a washer stem does after a few thousand cycles. For a property manager running a lot of units, that is the difference between a faucet that gets a service call every couple of years and one that does not.
