American Standard Studio S 1.8 gpm/6.8 L/min Shower Trim Kit With Rain Showerhead, Double Ceramic Pressure Balance Cartridge With Lever Handle - AMS-TU105507

Trim only. The Studio S TU105507 kit gives you the escutcheon, metal lever handle, 8 inch rain showerhead, and a 12 inch shower arm with flange. It is made for use with American Standard Flash shower rough-in valves, so the rough-in body has to be ordered separately or already be in the wall. Order both lines on the same job or the shower cannot be finished.

Maximum flow is 1.8 gpm (6.8 L/min) through the 8 inch rain head, which American Standard describes as saving 30 percent water. That puts it below the 2.5 gpm federal maximum and at the level most water-conservation and green-building shower specs call for. For a hotel or multi-family retrofit where the whole property is being brought down to a 1.8 gpm standard, this trim does it without an aftermarket restrictor.

Yes, and you do not have to re-pipe. The double ceramic pressure balance cartridge has back-to-back capability, meaning hot and cold can be reversed quickly at the cartridge. That is the common case on back-to-back bathrooms in apartments and hotels where one riser feeds two showers and one of them comes up mirrored.

That is what the pressure balance cartridge is there for. A ceramic balancing spool holds output temperature steady when hot and cold supply pressures shift, so a flushed toilet or a started dishwasher does not spike the shower. On top of that there is an adjustable hot limit safety stop that caps how much hot water can enter the mix, which is the setting you dial down in senior housing, schools, or any facility where you want a lower ceiling at the fixture.

Four: polished chrome (TU105507.002), matte black (TU105507.243), brushed nickel (TU105507.295), and brushed cool sunrise (TU105507.GN0). Chrome and brushed nickel are the safe matches when you are standardizing a building against existing American Standard trim; matte black and brushed cool sunrise are the design finishes and are the ones to sample before committing a full floor, since the showerhead, arm, flange, escutcheon, and handle all arrive in the same finish as a set.

The kit ships a 12 inch (300 mm) shower arm and flange, which sets the 8 inch (200 mm) rain head roughly a foot out from the wall face. That is the reach you want if you are spraying down the middle of a standard tub or shower base rather than at the wall. If the layout needs the head centered further out, or dropped from the ceiling, the arm is the piece you swap, not the trim.

One metal lever handle, one function. It controls volume and temperature together through the pressure balance cartridge and feeds the single rain head. There is no diverter here, so if the design calls for a hand shower or body sprays on the same valve, this trim will not run them; you need a trim with a diverter or a separate volume control.

The mixing valve and the balancing spool are both ceramic, and American Standard states the ceramic material is unaffected by mineral deposits and harsh water conditions. It is a one-piece cartridge, so when maintenance is eventually needed a tech pulls and replaces one part instead of rebuilding a stack. That matters more on a 200-unit portfolio than on a single bathroom.

No. Integrated check valves in the cartridge are there to eliminate cross flow, which is the failure that shows up as cold water creeping warm at other fixtures. Nothing extra has to be added at the valve to get it.

Brass wall escutcheon and a metal lever handle, not plastic. That is the distinction worth checking on a rental or dorm shower, where a plastic handle is the part that gets snapped off first.
