American Standard Studio S 2-Handle Integrated Shower Diverter Trim Only - AMS-TU105740

No. TU105740 is trim only. You also need the Flash Rough-in Integrated Shower Diverter Valve RU520 with 2 or 3 way discrete capability, ordered separately. The trim kit does include the discrete diverter valve and the pressure balance cartridge M970787-0070A, so the rough-in valve is the only extra piece on the plumbing side.

Depends on the rough-in you pair it with. The trim is built for the RU520 integrated shower diverter valve, which is available with 2 way or 3 way discrete capability. Two outlets (head plus hand shower or body sprays) works on the 2 way; a third outlet needs the 3 way version of that rough-in. Pick the rough-in by outlet count before you set the valve in the wall, since the trim will not add outlets the body does not have.

No. This trim mounts to the American Standard Flash RU520 integrated shower diverter rough-in, not to a generic two-handle valve body. The two levers here are function levers (temperature and diverter) off one pressure balance body, not separate hot and cold stems, so an old hot/cold two-valve setup has to be repiped to the RU520 body before this trim goes on.

Bottom lever is the control: it turns the water on and sets temperature. Top lever is the diverter, sending the water to the outlet you want. That is why it is a single plate with two levers rather than a separate valve trim plus a wall diverter, which matters when you are working a tight wet wall or want one escutcheon instead of two.

Yes. It uses a double ceramic pressure balance cartridge, which holds outlet temperature steady when hot or cold supply pressure changes, and the ceramic seats are what keep it from dripping as it ages. For a multi-family or hotel property that is the practical difference between a callback and no callback on a shared riser.

Yes. The pressure balance cartridge is a serviceable part, M970787-0070A, and it ships with the trim kit. Worth noting the number in your maintenance record so a future drip is a cartridge swap rather than a trim replacement.

Four: chrome (TU105740.002), matte black (TU105740.243), brushed nickel (TU105740.295), and brushed cool sunrise (TU105740.GN0). If you are standardizing a building, order by the suffix, that is the only thing that changes between them.

Metal. The trim kit is all metal construction, levers and plate, which is the reason it survives tenant turnover and commercial cleaning better than a plated plastic trim.
