American Standard Colony PRO Single Hole Single-Handle Bathroom Faucet 1.2 gpm/4.5 Lpm Less Drain With Lever Handle - AMS-7075104

The Colony PRO 7075104 is a single hole faucet, so it mounts through one deck opening. If your sink or countertop is drilled 4 inch centerset (three holes), you'd need a deck plate to cover the outer two, or a centerset model instead. On a lavatory drilled for a single hole it drops straight in.

No drain comes with it. The 7075104 is the less-drain version: no pop-up hole, no lift rod, no drain body. You order the drain separately, and because there is no lift rod hole in the faucet body, a grid drain or a push-button (click) drain is the match, not a rod-operated pop-up.

It runs 1.2 gpm / 4.5 Lpm through a pressure-compensating aerator. That is below the common 1.5 gpm lavatory ceiling, so it satisfies specs written at 1.5 gpm or lower down to 1.2. The pressure-compensating aerator holds that rate steady rather than letting flow climb on high-pressure supply lines, which matters when you are standardizing a building of restrooms.

Supply hoses are in the box. Braided flexible hoses with compression connectors come attached, so you're connecting to standard compression angle stops without buying separate risers. What you still need on the truck: a drain (this one ships less drain) and, if the stops are old, new angle stops.

Three: chrome (7075104.002), brushed nickel (7075104.295), and matte black (7075104.243). Those suffixes are how you order the finish, and they're the numbers to give a distributor if you're matching what's already installed on other units in a building.

Metal body and a metal lever handle. That's the reason it holds up in rental and multi-family turns where a plastic-bodied builder faucet gets loose at the handle. Inside it uses a ceramic disc valve, which is the cartridge type that resists drips from grit in the supply rather than wearing a rubber seat.

Yes, the ceramic disc valve has an adjustable hot limit safety stop. You set how far the handle can swing toward hot at install, which caps outlet temperature at the fixture and helps prevent scalding. That's set per faucet, so it's an install step to add to your punch list when you're rolling these out across a facility.

A single lever is the handle style to specify when you want operation without grasping or twisting. The Colony PRO 7075104 uses a metal lever, and it's a single-handle mixer, so one motion controls both temperature and volume. Red and blue indicators are marked on it so a user can see hot from cold at a glance.
