American Standard Serin 1.75 gpm/6.6 L/min Tub and Shower Trim Kit With Water-Saving 3-Function Shower Head, Double Ceramic Pressure Balance Cartridge With Lever Handle - AMS-TU064508

No. TU064508 is trim only: showerhead, shower arm and flange, metal wall escutcheon, metal lever handle, and a metal slip-on diverter tub spout. It's made for use with American Standard Flash shower rough-in valves, so you order the rough-in valve body separately. If the wall is already open, get the valve on site before you close it up.

It runs a double ceramic pressure balance cartridge: a ceramic disc mixing valve paired with a ceramic balancing spool in one piece. The spool holds output temperature constant when hot or cold supply pressure shifts, and ceramic isn't affected by mineral deposits or hard water. There's also an adjustable hot limit stop to cap how much hot water can mix in, which is what you set to reduce scald risk in rental or senior housing units.

Yes. The cartridge has back-to-back capability, so hot and cold can be reversed quickly during install. That covers back-to-back bathroom layouts and the occasional rough-in where the supplies got piped opposite. Integrated check valves are built in to stop cross flow between hot and cold.

1.75 gpm (6.6 L/min) maximum from the 4-3/4 inch, 3-function showerhead, which American Standard rates as a 28% water saving. That figure matters on multi-family and hospitality retrofits where a 2.5 gpm head is being swapped out to hit a water-conservation target.

Two: polished chrome (TU064508.002) and brushed nickel (TU064508.295). If you're standardizing bathrooms across a property, those are the part numbers to spec so every unit matches.

It's built as a tub-and-shower set. The kit includes a metal slip-on diverter tub spout, and the diverter in that spout is what sends water up to the head, so it's meant for an opening with a tub. For a shower-only stall you'd want a shower-only trim kit instead.

The handle, wall escutcheon, and tub spout are all metal. The spout is a slip-on style, so it slides over the copper nipple and sets with a screw rather than threading on, which changes what your plumber needs stubbed out at the wall.

No. The pressure balance cartridge is a one-piece unit that pulls and replaces as a single part, which is the point of that design for maintenance. The ceramic disc mixing valve is what handles shutoff, so a drip is normally a cartridge swap behind the escutcheon, not a valve body replacement.

It uses a single metal lever rather than a knob, and the ceramic disc mixing valve is specified for smooth handle operation, so it turns with one hand and no gripping or twisting. That's the reason lever trim gets spec'd in senior housing and accessible units.

Yes, it's a 3-function head measuring 4-3/4 inches (120 mm), so the spray switches between three patterns at the head itself. Flow stays capped at 1.75 gpm across the functions.
