American Standard Townsend 1.75gpm/6.6 L/min Tub and Shower Trim Kit With Water-Saving Showerhead, Double Ceramic Pressure Balance Cartridge With Lever Handle - AMS-TU353508

Trim only. The Townsend TU353508 kit gives you the showerhead, shower arm and flange, brass wall escutcheon, metal lever handle and slip-on diverter tub spout. The valve body is separate, and this trim is made for American Standard Flash shower rough-in valves. Order the Flash rough-in along with it or the job stalls at the wall.

Yes, the diverting is built into the tub spout. The kit ships with a slip-on diverter tub spout, so you pull the spout diverter to send water up to the head. That also means the spout slips onto a copper stub rather than threading on, so your existing nipple type decides whether it drops in.

No. The Townsend cartridge has back-to-back capability, meaning hot and cold can be reversed at the cartridge without repiping. That is the usual fix on back-to-back bathrooms in apartments and hotels where one of the two valves ends up mirrored.

The showerhead runs 1.75 gpm / 6.6 L/min maximum, so it sits under a 1.8 gpm cap. American Standard states it saves 30% water compared to a standard head. For multi-family or hospitality retrofits where a conservation number is written into the scope, that 1.75 figure is the one to put on the submittal.

Pressure balance. The double ceramic cartridge combines a ceramic disc mixing valve with a ceramic balancing spool, which holds output temperature steady when hot or cold supply pressure changes (someone flushing a toilet elsewhere in the unit). It is a single-handle setup, so temperature and volume come off the one lever. If you need independent volume control or a fixed set temperature, a thermostatic valve is the different animal you want.

Yes. The cartridge has an adjustable hot limit safety stop that caps how much hot water is allowed into the mix, which is what you set to reduce scald risk on a unit turnover or in senior housing. It is adjusted at the cartridge, so set it once the trim is on and the water is live.

Six: chrome (TU353508.002), polished nickel (.013), matte black (.243), legacy bronze (.278), brushed nickel (.295) and brushed cool sunrise (.GN0). The suffix on the part number is the finish, so if you are standardizing a building on one look, spec the suffix and the rest of the number stays put across every unit.

No, check valves are integrated into the cartridge to eliminate cross flow, so there is nothing extra to add on that count. Cross flow is what causes hot to creep into a cold-only fixture nearby, and it is the first thing to rule out when a tenant reports warm water at the cold tap.

The mixing valve and balancing spool are in one piece, so a service call is a single cartridge swap rather than sorting two components in the wall. The sealing surfaces are ceramic disc, which American Standard rates for drip-free performance and is unaffected by mineral deposits and hard water. For a maintenance department carrying spares across a portfolio, that is one part number on the shelf per opening.

Metal on both. The handle is a metal lever and the wall escutcheon is brass. A lever also takes less grip strength than a knob, which matters when you are fitting out units meant to be usable by residents with limited hand mobility.
