American Standard Townsend Valve Only Trim Kit With Double Ceramic Pressure Balance Cartridge and Lever Handle - AMS-TU353500

No. The Townsend TU353500 is valve-only trim, so you get the brass wall escutcheon, metal lever handle and the double ceramic pressure balance cartridge, but not the rough-in valve body. It is made for use with American Standard Flash shower rough-in valves, which you order separately.

It is specified for American Standard Flash shower rough-in valves. If the valve already in the wall is a Flash body, the trim and its one-piece cartridge drop straight on. If it is another manufacturer's valve or an older non-Flash American Standard body, this trim is not the right part.

Four finishes, each with its own part number: chrome (TU353500.002), polished nickel (TU353500.013), legacy bronze (TU353500.278) and brushed nickel (TU353500.295). The suffix after the dot is the finish code, so if you are matching other Townsend trim already in the bathroom, match that suffix.

Pressure balance. The Townsend TU353500 uses a one-piece double ceramic cartridge that combines a ceramic disc mixing valve with a ceramic balancing spool, so it holds output temperature steady when hot or cold supply pressure shifts (a toilet flushing elsewhere in the unit). It is not a thermostatic valve, so it does not hold a dialed-in degree setting independent of volume.

Yes. The Townsend trim has an adjustable hot limit safety stop that caps how much hot water can mix with cold, which is how you dial back scald risk in guest rooms and rental units. The comfort zone feature also widens the usable range of the handle so tenants can fine tune within that band.

Yes. The cartridge has back-to-back capability, so hot and cold can be reversed at the cartridge rather than reworking the supply piping. That is the common fix on back-to-back bathroom stacks where the rough-in was piped mirrored.

No separate cartridge purchase. The double ceramic pressure balance cartridge comes as part of the Townsend TU353500 kit as a single one-piece unit, which is also what makes later service a swap rather than a rebuild. What you still need is the Flash rough-in valve body if one is not already in the wall.

Integrated check valves are built in to eliminate cross flow, so hot does not migrate into the cold line through the valve. That matters where the shower shares a wall or a supply run with other fixtures and you are chasing a warm cold-water complaint.

The handle is a metal lever and the wall escutcheon is brass, not plated plastic, which is what property managers and MRO buyers usually want in tenant and public restrooms. The ceramic disc mixing valve is also unaffected by mineral deposits and hard water, so it resists the sticky, dripping handle you get from scaled-up cartridges.
