American Standard Portsmouth Round Tub and Shower Trim Kit with Water-Saving Showerhead and Double Ceramic Pressure Balance Cartridge with Lever Handle - AMS-TU420502

No. The Portsmouth TU420502 is trim only, and it is made for use with American Standard Flash shower rough-in valves. You order the Flash rough-in body separately and set it in the wall during rough plumbing, then the trim goes on at finish. What comes in the kit is the showerhead, shower arm and flange, metal wall escutcheon, metal lever handle, and the metal slip-on diverter tub spout.

The Spectra+ Fixed Traditional showerhead is 7-1/4 inches and flows 1.8 gpm (6.8 L/min), which American Standard describes as a 28 percent water saving. That 1.8 gpm rate is below the 2.5 gpm federal maximum and meets the 1.8 gpm threshold used by water-conscious specs in states like California and Colorado, which matters if you are standardizing units across a multi-family or hospitality property.

It ships with a metal slip-on diverter tub spout. Slip-on means it slides over a 1/2 inch copper stub-out and is secured with a setscrew, so it will not thread onto a 1/2 inch IPS nipple. If your existing spout threads on, you will need to change the stub-out to a copper nipple of the correct length or choose a threaded spout instead.

Yes. The double ceramic pressure balance cartridge has back-to-back capability, so hot and cold can be reversed quickly if the supplies come into the wall backward, which is common on shared walls between two bathrooms. It also has integrated check valves to stop cross flow between the hot and cold lines.

It uses a double ceramic pressure balance cartridge, a ceramic disc mixing valve paired with a ceramic balancing spool in one piece, which holds outlet 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, to reduce the risk of accidental scalding. That stop is field-adjustable, which is what you want in senior housing or a school where you are setting a maximum outlet temperature.

Brushed nickel, ordered as TU420502.295. All the visible pieces are metal, including the lever handle, the wall escutcheon and the tub spout, so the finish carries across the whole set rather than sitting on a plastic spout. If you are matching other Portsmouth trim on a property, match on the .295 suffix.

There is no second handle. Diversion is in the tub spout itself, a pull-up style diverter on the metal slip-on spout, and the single lever handle controls both volume and temperature. That means the rough-in only needs one valve body, not a separate diverter valve.

Not as shipped. The TU420502 is built around a diverter tub spout, so it assumes a tub filler outlet below the valve. For a shower-only stall you want a shower-only trim kit, which has no spout and no diverter, paired with a Flash rough-in valve plugged at the bottom outlet.

It is a one-piece cartridge, so a service call means pulling and swapping that single unit rather than opening the wall. The mixing valve and balancing spool are ceramic, which American Standard notes is unaffected by mineral deposits and harsh water conditions, so hard-water buildings tend to get longer runs between cartridge changes than with rubber-seat designs.
