MultiChoice High Flow w/ Stops Rough-In Valve Body w/ 1/2" Universal Inlets/Outlets, Shower Only, R10000-UNWSHF

The Delta MultiChoice R10000-UNWSHF is a high flow rough-in valve body engineered for shower-only installations, giving you the flexibility to change trim styles, functions, and finishes down the road without ripping open your walls. This valve accepts 1/2" universal inlets and outlets, integrates built-in screwdriver stops for easy service shutoff, and features a blocked tub port so you don't need an additional plug in shower-only applications. It's designed for pros who want installation speed now and upgrade options later, all while maintaining compatibility with Delta's MultiChoice trim ecosystem.

• High Flow Design: This valve is built to deliver higher water volume than standard rough-ins, supporting modern shower systems that demand robust flow rates for rain heads, body sprays, and multi-function trims.
• 1/2" Universal Inlets and Outlets: Accepts 1/2" copper sweat, 1/2" threaded iron pipe, PEX, or CPVC connections, eliminating the need to stock multiple valve types and simplifying installation across different plumbing systems.
• MultiChoice Universal Compatibility: The valve body accepts Delta's single function (13/14 series), dual function (17 series), or dual function thermostatic (17T series) cartridges, allowing you to change shower operation and style without altering the plumbing behind the wall.
• Integrated Screwdriver Stops: Built-in service stops let you shut off water to the valve for cartridge or trim service without killing supply to the entire house, saving time on maintenance calls and reducing disruption.
• Blocked Tub Port (HF Models): High flow rough valves feature a factory-blocked tub port, eliminating the step of installing a separate plug when the valve is used in a shower-only application.
• Back-to-Back Capability: Install two showers on opposite sides of the same wall by mounting valves back-to-back, a space-saving feature for multi-unit construction or efficient bathroom layouts.

This rough-in valve body is compatible with Delta MultiChoice single function, dual function, and dual function thermostatic cartridges (cartridge ships separately with the trim kit, not with the valve body). It accepts standard 1/2" plumbing connections in copper, iron pipe, PEX, or CPVC. The valve is designed for shower-only applications and should not be used where a tub spout is required unless paired with a separate diverter rough (such as the Delta R11000). Back-to-back installations are supported when space and framing allow.

The valve installs during rough-in and mounts to standard framing. Universal inlets accept sweat or threaded connections, and outlets accommodate the same range of pipe types. Integrated stops are accessible with a standard screwdriver for service shutoff. The cartridge (which controls flow and temperature) is installed later with the trim kit and is not included with this rough valve body.

Delta provides warranty coverage and support for this valve body, though specific terms are determined by Delta and typically extend to the original purchaser. Consult Delta's documentation or contact their support team for detailed warranty duration and coverage specifics.

A: The high flow version (R10000-UNWSHF) is engineered to deliver higher water volume, making it suitable for modern shower systems with rain heads, body sprays, or multiple outlets that require robust flow rates. Standard rough-ins may restrict flow in high-demand applications. Additionally, high flow models feature a blocked tub port, eliminating the need for a separate plug in shower-only installations.

A: No. This is a valve body only. The cartridge (which controls water flow and temperature) ships separately with the Delta trim kit you select. The MultiChoice system is designed this way so you can choose your preferred trim style, finish, and function (single, dual, or thermostatic) without being locked into a specific cartridge at rough-in.
