American Standard Colony PRO 4-Inch Centerset Single-Handle Bathroom Faucet 0.5 gpm/1.9 L/min With Lever Handle - AMS-7075050

Yes. The Colony PRO 7075050 is a 4-inch centerset, so it mounts on a sink or vanity top drilled with holes on 4-inch centers. It is a single-handle faucet on a centerset body, so the spout and lever come as one assembly covering all three holes. It will not work on an 8-inch widespread layout or on a single-hole top without a deck plate sized for that configuration.

The Colony PRO 7075050 runs a maximum 0.5 gpm (1.9 L/min), which is a commercial lavatory flow rate, not a residential one. That is the right call for high-traffic public washrooms, schools, and offices where water use is metered and jurisdictions cap lavatory flow. For a residential bath where users expect a faster fill, 0.5 gpm will feel slow and you would want a 1.2 gpm aerator model instead.

Yes. The Colony PRO 7075050 has an adjustable hot-limit safety stop built into its 35 mm ceramic disc cartridge, so you can set how far the lever travels toward hot. That is set during or after install and is the feature facilities buyers look for in schools, senior housing, and healthcare washrooms where tempered water matters.

Chrome only, under part number 7075050.002. If you are standardizing a floor of restrooms or matching existing trim, chrome is the single option on this model, so brushed nickel or matte black openings need a different Colony PRO number.

What ships with the Colony PRO 7075050 is the faucet itself with its lever handle, plus both the hot/cold red and blue index plug buttons and a color matched plug button so you can finish the handle either way. Plan on sourcing supply connections and a drain separately if the job needs them.

For MRO work it usually is. The Colony PRO 7075050 uses one lever over a single 35 mm washerless ceramic disc cartridge, so there is one cartridge to stock and one part to swap instead of two stem assemblies. Ceramic disc means no washers to replace as a routine item. The lever itself also takes a push or a forearm rather than a grip, which is why lever trim is standard on public washroom specs.

Metal. The Colony PRO 7075050 is built with durable metal construction rather than a plastic body, which is what you want on rental turns and commercial restrooms where the faucet gets leaned on and cleaned with harsh chemicals. Chrome plated over that metal body on part number 7075050.002.

One person. American Standard builds the Colony PRO 7075050 for simple one-person installation, which on a centerset means the body seats through all three holes as a unit and tightens from below without someone holding the spout topside. On a rough-in of a dozen lavatories that is the difference between one plumber and two.

It does. Memory Position Valving on the Colony PRO 7075050 holds the lever's last temperature position, so the user gets the same mix each time without readjusting. Combined with the hot-limit stop, that gives a predictable delivered temperature across a bank of lavatories where you do not want occupants fiddling with the handle.
