American Standard Colony PRO 1.75 gpm/6.6 L/min Tub and Shower Trim Kit With Water-Saving Showerhead, Double Ceramic Pressure Balance Cartridge With Lever Handle - AMS-TU075508

Trim only. The TU075508 Colony PRO kit gives you the showerhead, shower arm and flange, wall escutcheon, metal lever handle and slip-on diverter tub spout, and it is made for use with American Standard Flash shower rough-in valves. The rough-in valve body goes in behind the wall and is ordered on its own, so plan on both lines when you're pricing a bathroom out.

The showerhead is rated 1.75 gpm/6.6 L/min maximum flow, below the 2.5 gpm federal ceiling and at the level most water-conservation programs ask for. American Standard puts the saving at 30 percent of normal usage. For a property manager or institutional buyer standardizing on low-flow across a building, that number is the one your water audit will want.

Yes, it's pressure balance. The trim runs a double ceramic cartridge combining a ceramic disc mixing valve with a ceramic balancing spool, and the spool holds output temperature steady when hot and cold supply pressures shift, which is exactly what happens when a toilet flushes or a washer fills elsewhere on the line. Ceramic doesn't care about mineral deposits or hard water, so it's a sensible choice in buildings with aggressive water. It is not a thermostatic valve; there's no separate temperature dial, one lever sets both volume and temperature.

There's an adjustable hot limit safety stop built into the valve that caps how much hot water can mix with cold, which is the standard way to reduce scald risk on units where residents can't react quickly. It's set at installation and adjusted at the cartridge, so a maintenance tech can dial it back on a whole floor of units without changing hardware. The Comfort Zone feature widens the usable range within that limit so the handle still gives fine control after you've restricted the top end.

No re-piping needed. The Colony PRO valve has back-to-back capability, so hot and cold can be reversed quickly at the valve itself. That's a common save on back-to-back bathrooms sharing a wall, where one side ends up mirrored. The escutcheon carries red/blue indicators, so re-mark them to match after you reverse it.

It's a slip-on diverter spout. It slides over a length of copper stub-out and locks with a setscrew rather than threading onto a nipple, so the wall rough-in has to be a plain copper tube, not a threaded nipple. If the existing stub-out in the wall is threaded IPS, that spout won't mount without changing the stub-out. Worth checking before the tech is standing in the tub, because the two rough-ins are not interchangeable.

Tub and shower. The kit includes a diverter tub spout, so water runs to the spout by default and pulls up to the showerhead, which means it's meant for a bathtub with a shower above it. If the opening is a stall shower with no tub, this isn't the right kit, you want a shower-only trim without the spout.

Three finishes: chrome (TU075508.002), brushed nickel (TU075508.295) and matte black (TU075508.243). Chrome is the usual multi-family and hospitality standard because it matches the widest range of existing fixtures; brushed nickel and matte black are the ones to pick when you're refreshing a unit to current rental-market styling. All three are the same trim kit and the same valve behavior, only the finish differs.

Integrated check valves in the Colony PRO valve are there to eliminate cross flow, which is what causes hot water to bleed back into the cold supply and show up warm at other fixtures. They're built into the valve rather than being a separate part you add, so there's nothing extra to order for that.

The mixing valve and the balancing spool sit in a single one-piece cartridge, so a service call is one part pulled and one part put back rather than sorting through a stack of components. The ceramic disc mixing valve is the wearing surface, and ceramic discs are what gives drip-free service and the smooth handle feel over time. For a maintenance shop stocking spares across a portfolio, one cartridge type covers every unit trimmed with this valve.

The showerhead measures 3-3/4 inches (96 mm). That's a compact face rather than a rain-style head, which keeps it under the standard shower arm height in a low-ceiling bathroom and keeps the spray pattern tight at the 1.75 gpm flow. A shower arm and flange come with the kit.

Metal lever handle. That matters in rentals and hospitality where the handle takes daily force from every occupant and a plastic lever is the part that snaps first. The lever style also means it can be operated without gripping or twisting the wrist.
