The Moen Posi-Temp Eco-Performance Shower Trim Kit, Valve Required is a single-handle shower trim set designed to update the visible components of a shower installation. It includes a showerhead and uses a rotational Posi-Temp valve for turning the water on and adjusting temperature. The valve is required separately, so compatibility with the existing or planned valve should be confirmed before installation.
Quick Overview
This shower trim kit combines a classic chrome appearance with pressure-balancing temperature control and a water-efficient 1.75 GPM showerhead. Its control is intended for on/off operation and temperature adjustment, rather than separate flow-rate or volume control. The kit is designed for use with compatible Moen Posi-Temp valves, including valve numbers 2510, 2520, 2570, or 2590.

What the Shower Trim Kit Includes
A shower trim kit covers the components that are visible after a shower valve has been installed behind the wall. In this case, the set includes the showerhead and the visible control trim associated with a Moen Posi-Temp installation. It is intended for a shower-only setup, rather than a tub-and-shower arrangement with a tub spout.
The required valve is not included. Compatible valve options identified for this trim include Moen Posi-Temp models 2510, 2520, 2570, and 2590. Because the valve is part of the behind-the-wall plumbing, checking the installed valve or selecting the valve before beginning a new installation is an important step.
Temperature Control and Valve Operation
The Posi-Temp pressure-balancing design helps maintain a more consistent water temperature when water pressure changes elsewhere in the plumbing system. This feature is intended to help reduce sudden hot or cold fluctuations during use.
The control uses a cycling, or rotational, Posi-Temp valve. Rotating the handle turns the water on and adjusts the temperature. The trim does not provide a separate volume-control function, so it is not designed to independently regulate the water flow rate through the handle. This distinction may matter if a bathroom design calls for separate controls for temperature and water volume.
Water-Efficient Showerhead
The included showerhead has a stated flow rate of 1.75 gallons per minute and is identified as meeting EPA WaterSense criteria. A lower-flow showerhead can help reduce the amount of water used during showers while remaining within the performance requirements associated with the WaterSense designation.
Flow rate is only one part of the shower experience. Water pressure in the home, plumbing conditions, and the existing valve can also affect how the shower operates. The 1.75 GPM specification provides a useful point of comparison when reviewing other showerheads or considering household water use.
Chrome Appearance
The trim has a chrome finish with a highly reflective, mirror-like appearance. Chrome is commonly used in bathrooms because it coordinates with a wide range of fixture styles and surrounding hardware. Its simple look may suit installations where the goal is to replace worn or outdated visible trim without introducing a highly decorative design.
The product information does not provide dimensions or detailed construction materials. Anyone replacing an existing trim set should compare the installation requirements and visible component measurements before removing the current hardware.
Installation and Compatibility Points
The most important installation consideration is that the valve is required separately. A trim kit cannot complete the plumbing system by itself. The compatible valve must already be installed or purchased as part of a new installation, and the specific valve arrangement should be checked before work begins.
- Confirm that the installation uses a compatible Moen Posi-Temp valve.
- Check whether the existing valve is one of the identified models: 2510, 2520, 2570, or 2590.
- Remember that the handle controls temperature and on/off operation, not independent water volume.
- Verify that the project requires a shower-only trim kit rather than a tub-and-shower set.
- Compare the existing visible trim and connection requirements with the installation instructions before starting.
For a renovation where the plumbing behind the wall remains in place, valve compatibility deserves particular attention. Replacing only the visible trim may be straightforward when the existing valve is compatible, but a mismatched valve can require additional plumbing work. Installation should follow the manufacturer’s instructions, and complex or behind-the-wall plumbing work may require a qualified professional.
Who It May Be Suitable For
This trim kit may be suitable for a bathroom update that needs a showerhead and single-handle temperature control in a straightforward chrome design. It may also appeal to households looking for a WaterSense-designated 1.75 GPM showerhead and pressure-balancing temperature control.
It may be less suitable for someone who wants a separate control for water volume, a tub spout, or a multi-function shower system. Those requirements call for a different trim configuration with the necessary components and controls.
Questions to Consider Before Choosing It
Before selecting the Moen Posi-Temp Eco-Performance Shower Trim Kit, Valve Required, consider whether the bathroom already has a compatible valve. Also determine whether the existing shower layout needs only visible trim and a showerhead, or whether it requires a complete tub-and-shower arrangement.
The chrome finish and single-handle format are relatively straightforward, but appearance and operating style are personal preferences. If a different finish, a lever with separate volume control, or additional shower functions are required, compare those specifications with the needs of the installation rather than assuming they are included.
Frequently Asked Questions
Is the valve included with this shower trim kit?
No. A compatible Moen Posi-Temp valve is required and sold separately. The identified compatible valve numbers are 2510, 2520, 2570, and 2590.
Does the handle control water volume?
No. The cycling Posi-Temp operation is designed for turning the water on and adjusting temperature. It does not provide separate water-volume control.
What is the showerhead flow rate?
The showerhead is specified at 1.75 gallons per minute and is identified as meeting EPA WaterSense criteria.
Does the kit include a tub spout?
No tub spout is identified for this shower trim kit. It is intended for a shower-only installation. A tub-and-shower trim kit would be a different configuration.
What finish does the trim have?
The trim has a chrome finish with a highly reflective appearance.

Final Thoughts
The Moen Posi-Temp Eco-Performance Shower Trim Kit, Valve Required is a shower-focused trim option with a chrome finish, pressure-balancing temperature control, and a 1.75 GPM WaterSense showerhead. Its main limitation is also an important installation detail: the compatible Posi-Temp valve must be supplied separately. Confirming the valve, control requirements, and shower-only configuration can help determine whether this trim kit fits the planned bathroom installation.
