Shower Diverter Rough-in Valve Replacement for D R11000 3-Setting 6-Setting
This Tearel unit is forged from solid brass and features a 3-port diverter that directs water flow between the mixing valve and the desired application. It is a diverter-only option, meaning temperature control requires pairing with a compatible valve like the Delta R10000. Best for homeowners who already have a compatible control valve and simply need a robust diverter path.
Who this is best for: a DIYer replacing a diverter path in a Delta-compatible setup or a contractor upgrading an aging rough-in with a dedicated diverter module. Limitation: it does not provide integrated temperature control, so you must ensure compatible temperature management upstream.

The Delta R22000 offers universal compatibility with multiple trim configurations, plus a built-in pressure balance feature that keeps water temperature within a safe range. This rough-in valve is designed for flexible upgrade paths and is ideal for remodels where future trim changes might be anticipated. Best for buyers who want long-term versatility and reliable temperature stability.
Best for: homes needing a future-proof solution that can adapt to various trim kits. Caution: this unit is a rough-in only and requires an external trim kit and valve assembly for full installation.

RJDIBAN’s rough-in valve is crafted from solid brass with a customizable 3-port design that directs water flow to the chosen outlet. It includes a diverter cartridge and is designed to work with R10000-series trim kits for temperature control. Best for buyers who want a durable brass option with clear trim compatibility and straightforward installation.
Choose this if you’re aiming for a sturdy, trim-compatible diverter that remains simple to install. Limitation: ensure you pair it with the right trim kit to achieve full functionality and temperature control.
Delta Faucet R11000 3-Setting and 6-Setting Diverter Kit
This Delta kit is built for use with 3 or 6-function diverter configurations and features a forged brass body for durability. It comes with a test cap to facilitate pressure testing before trim installation. Best for Delta-focused installations where a trusted, compatible rough-in with testing provisions is desired.
Best for: Delta-centric projects needing a ready-to-install rough-in with testing capabilities. Limitation: this is a kit and assumes you will install a Delta trim compatible with the R11000 family.
DELTA FAUCET Universal Integrated Diverter Rough
This Delta model features a universal rough-in with integrated diverter and a forged valve body. It is a rough-in only unit, designed for installations where a complete trim kit will be added later. Best for remodels seeking a robust universal rough-in that aligns with Delta’s MultiChoice system.

It’s designed to remain behind the wall, enabling extensive trim customization without changing plumbing. Best for comprehensive Delta shower upgrades where trim flexibility is needed.

Buying Guide: Key Purchase Considerations
- Compatibility: Check whether the rough-in valve supports your chosen trim kit and whether you need a 3-setting or 6-setting diverter. If you plan future trim upgrades, a universal option (like Delta MultiChoice) provides more flexibility.
- Temperature Control: Some rough-ins are solely diverters and rely on a separate mixing valve. If stable temperature control is essential, choose models that include or pair with a pressure-balancing mechanism.
- Brass Construction: Brass bodies tend to offer durability and longevity in wet bathroom environments. Expect better long-term reliability with brass compared to mixed-metal alternatives.
- Inlet/Outlet Configuration: Ensure the rough-in has the correct 1/2 inch or other connections to fit your plumbing lines and trim kit adapters.
- Maintenance and Testing: Look for rough-ins that support pressure testing (air or water) during installation to verify seals before completing the wall work.
- Ease of Installation: Some kits come with additional components (stops, test caps) that simplify setup. If you lack specialized tools, choose models designed for straightforward DIY installation.
Frequently Asked Questions
- What is a rough-in diverter valve used for?
It provides the directional control of water flow to different shower outlets, often requiring a separate trim kit or mixing valve for temperature control.
- Do I need a universal rough-in valve?
Universal rough-ins offer greater future flexibility for trim upgrades and can simplify future remodels, especially in homes with varying plumbing layouts.
- Can I install a diverter rough-in myself?
Yes, many rough-ins are designed for DIY installation, but confirm compatibility with your trim kit and follow local plumbing codes. Consider professional help for complex plumbing layouts.
