American Standard Colony PRO 4-Inch Centerset Single-Handle Bathroom Faucet 0.5 gpm/1.9 L/min With Lever Handle - AMS-7075056

Yes. The Colony PRO 7075056 is built for 4 inch center mounting, so it drops onto a standard three-hole lavatory deck drilled on 4 inch centers. It is a single-handle design, so the lever sits on the center hole and the escutcheon covers the two outer holes.

That is the point of this one. The Colony PRO 7075056 is rated at a 0.5 gpm / 1.9 L/min maximum flow, which is the low-flow rate specified for public and commercial handwashing lavatories where water use is being cut. If you are putting it in an apartment or residential bath where tenants expect a faster fill, a 1.2 gpm lavatory faucet will feel better at the sink.

Yes. The Colony PRO single-handle lavatory faucet uses a 35 mm washerless ceramic disc cartridge with an integral hot limit safety stop, and that stop is adjustable, so you can set how far the lever travels toward hot to reduce the risk of scalding. It also holds a Memory Position valve, meaning the handle returns to the temperature the last user set without readjusting.

On a deck already drilled for 4 inch centers, yes. The Colony PRO 7075056 is a single-handle centerset unit, so it goes back into the same three-hole pattern a previous centerset came out of. If your sink is drilled 8 inch widespread, this is the wrong configuration and you need a widespread faucet instead.

Chrome, ordered as part number 7075056.002. If you are standardizing a building, that is the one finish to spec across the openings, and the faucet ships with both the hot/cold red and blue index buttons and a color matched plug button so the handle can be finished to match either way.

Metal. The Colony PRO 7075056 is a metal-construction faucet rather than a plastic-bodied economy fixture, which is what you want in a restroom seeing heavy traffic or in a rental unit where the fixture gets handled hard.

American Standard builds the Colony PRO for one-person installation, so a single tech can set it and tighten from below without a helper holding the body up top. It mounts on 4 inch centers, so on a like-for-like centerset replacement the existing deck holes are already correct.

That is the Memory Position valving. The lever returns to the position that holds the preferred mix, so the next user gets the same temperature without hunting for it. Underneath it is a washerless ceramic disc cartridge, which is what keeps the handle smooth and the spout from dripping as the fixture ages.
