American Standard Edgemere 1.8 gpm/6.8 L/min Tub and Shower Trim Kit With Water-Saving Showerhead, Double Ceramic Pressure Balance Cartridge With Lever Handle - AMS-TU018508

No. The Edgemere TU018508 is trim only, and it is made for use with American Standard Flash shower rough-in valves. The rough-in valve body has to be ordered separately. What you get in the kit is the water-saving 5-3/4 inch showerhead, shower arm and flange, wall escutcheon, metal lever handle, and a metal slip-on diverter tub spout.

The kit ships a metal slip-on diverter tub spout, so it slides over a copper stub-out and tightens with a set screw rather than threading onto an IPS nipple. If your existing spout threads on, you would need to change the stub-out to a copper nipple, or pick a threaded-spout trim instead.

It uses a double ceramic pressure balance cartridge, combining a ceramic disc mixing valve with a ceramic balancing spool in one piece, which holds output temperature steady when hot or cold supply pressure changes. It also has an adjustable hot limit safety stop that caps how much hot water can mix in, reducing scald risk. Integrated check valves prevent cross flow between hot and cold.

That depends on the valve already in the wall. The Edgemere TU018508 is designed to dress an American Standard Flash rough-in valve, so if a Flash valve body is already installed you can swap escutcheon, handle, spout and head without cutting tile. Over a different manufacturer's valve body it will not mount, and the rough-in has to be changed.

The showerhead is rated at 1.8 gpm (6.8 L/min) maximum, which American Standard states saves 28 percent water usage. That puts it below the common 2.5 gpm showerhead figure, so it suits properties standardizing on reduced-flow fixtures. If you need a higher-flow head for an existing suite, that would be a different trim kit.

Yes. The valve trim has back-to-back capability, so hot and cold can be reversed quickly without special parts. That matters on back-to-back bathroom stacks in multi-family work where the plumber runs the supplies mirrored.

Three finishes: chrome (TU018508.002), brushed nickel (TU018508.295), and matte black (TU018508.243). Property managers standardizing a building can order the same trim across all units and only change the suffix.

Yes, one metal lever handle controls both temperature and volume through the pressure balance cartridge. The diverter is in the tub spout, not on the wall, so the valve escutcheon carries the single handle only.

The water-saving showerhead face measures 5-3/4 inches (147 mm) across, and it comes with its own shower arm and flange in the matching finish, so there is nothing extra to source for the shower riser.

Yes. The mixing valve and balancing spool are combined in a single cartridge, so maintenance staff pull and replace one part instead of two, and the ceramic material is unaffected by mineral deposits and hard water. That is the main reason this trim suits high-turnover multi-family and hospitality work.
