Chateau is a Moen single-lever line, and all four links here are chrome. Every sheet here names the 1255 Duralast cartridge, so one cartridge part covers the kitchen and bath models on this page. The Chateau L2352 shower valve is covered in our Moen shower faucet guide, and our Moen cartridge guide explains how to tell the 1255 from look-alikes.
Moen Chateau 7423: single-hole kitchen faucet
Choose the 7423 for a one-hole kitchen sink and the simplest install. Moen’s spec sheet (maker page: assets.moen.com/shared/docs/product-specifications/7423sp.pdf) lists metal construction with a chrome finish, 1/2-inch IPS connections that accept standard ball-nose 3/8-inch tubing, a lever handle that controls temperature through a 180-degree arc and operates with less than 5 pounds of force, the 1255 cartridge (the sheet notes “not 1200”) and a 1.5 gpm spout flow at 60 psi.
Moen says it installs through one hole at least 1-1/4 inches across, with a 2-inch maximum deck. The sheet lists a lifetime limited warranty to the original consumer purchaser and 5 years in commercial use. On October 15, 2026, the standard new offer sold by Amazon.com was in stock with model 7423, chrome.

Moen Chateau 7434: kitchen faucet with side spray in the deck plate
Choose the 7434 for a three-hole kitchen sink where you want a side spray built into the plate. Moen’s spec sheet (maker page: assets.moen.com/shared/docs/product-specifications/7434sp.pdf) lists metal construction, flexible supplies with 3/8-inch compression fittings, a Protégé side spray with Duralock quick connect, a lever with 100 degrees of travel that works with less than 5 pounds of force, the 1255 Duralast cartridge and a 1.5 gpm maximum spout flow.
It installs through three holes at least 1-1/4 inches across on 4-inch centers, and the drawing lists a 1-1/8-inch maximum deck thickness. The sheet lists a lifetime limited warranty to the original homeowner, 10 years multifamily and 5 years commercial. On October 15, 2026, the standard new offer sold by Amazon.com was in stock with model 7434, chrome.

Moen Chateau 7437: kitchen faucet with Protégé side spray
Choose the 7437 if you want a separate side spray. Moen’s spec sheet (maker page: assets.moen.com/shared/docs/product-specifications/7437sp.pdf) lists metal construction with a chrome finish, flexible supplies with 3/8-inch compression fittings, a Protégé side spray, a lever with 100 degrees of travel, the 1255 Duralast cartridge, a 1.5 gpm spout flow and a 2.0 gpm maximum when the flow is diverted to the side spray.
The sheet says it installs through two holes at least 1-1/4 inches across on 4-inch centers, one for the faucet and one for the spray. It also warns there is more than one version of this model, and one version of the sheet pairs the 7437 with a 7423 “less spray” layout, so check the drawing against your sink before you drill or swap. On October 15, 2026, the standard new offer sold by Amazon.com was in stock with model 7437, chrome.

Moen Chateau L4621: bathroom centerset
Choose the L4621 for a standard three-hole bathroom sink. Moen’s spec sheet (maker page: assets.moen.com/shared/docs/product-specifications/l4621sp.pdf) lists a single-handle centerset with a pivot-action lever, temperature controlled through 100 degrees of handle travel, 1/2-inch IPS connections, the 1255 Duralast cartridge and a metal pop-up drain. It installs through three holes, 1 inch in diameter and 2 inches on center, which puts the outer holes 4 inches apart: the standard centerset layout.
The sheet lists both 1.2 gpm and 1.5 gpm versions, marked on the product, and WaterSense certification for the 1.2 gpm marking. Related models on the same sheet include the L4601 without a drain and the L64621, sold as a bulk pack of 12 per carton. On October 15, 2026, the standard new offer sold by Amazon.com showed limited stock with model L4621, chrome.

One cartridge, two rooms
All four sheets name Moen’s 1255 Duralast cartridge. That matters later: if a Chateau faucet starts to drip or gets stiff, the same cartridge part fits the kitchen and bath models here. The 7423 sheet even flags “not 1200,” a reminder that older Moen single-handle faucets used a different cartridge. The 7423 sheet also says there is more than one version of that model, so compare the drawing with your faucet before you order parts for an older unit.
Handle travel. The 7423 swings through 180 degrees from cold to hot; the 7434, 7437 and L4621 through 100 degrees. With the longer arc, the same change in temperature takes more handle movement.
Effort. The kitchen sheets say the lever operates with less than 5 pounds of force, and all list ADA compliance for the lever handle.
Kitchen choice by sink holes
Count the holes in your kitchen sink. One hole: the 7423. Three holes 4 inches apart with no separate spray hole: the 7434, which puts the side spray in the deck plate. Two holes 4 inches apart, one for the faucet and one for a spray: the 7437 with its Protégé side spray, after checking its drawing for your version. If you have extra holes you will not use, a deck plate or a soap dispenser can cover them.
