American Standard Studio S Single-Handle Diverter Valve Trim Kit - AMS-T105430

No. The Studio S T105430 is trim only, the handle, escutcheon and plaster guard. The rough valve is sold separately, so you need to order the in-wall diverter valve body along with it or have one already set in the wall.

Only if the rough valve in the wall is the American Standard diverter body this trim is built for. The T105430 is a diverter trim, not a pressure-balance or thermostatic mixing trim, and trim kits are not interchangeable across valve bodies. If you are re-trimming an existing American Standard diverter of the matching rough, the trim swaps on without opening the wall.

Metal. The Studio S diverter trim uses a metal lever handle, which is what you want in rental or high-traffic bathrooms where plastic handles crack or spin off the stem.

No. A diverter only routes flow between outlets, for example tub spout to showerhead, or showerhead to a hand shower or body sprays. Temperature and volume are handled by the separate mixing valve trim. If you want one control doing both, you need a pressure-balance or thermostatic shower trim instead of this diverter.

Yes, it is part of the same Studio S design line and is a faucet-application trim, so the lever styling and finish coordinate with other Studio S fittings. Match the finish code, chrome .002, brushed nickel .295, matte black .243 or brushed cool sunrise .GN0, across the room for a consistent look.

The removable plaster guard protects the valve opening during tile, drywall and finish work, then pops off when you install the handle and escutcheon. On new construction that means the plumber can set the rough and leave, and the finish trim goes on at the end of the job without damage.
