OYIMNB R10000-UNBXHF Universal Shower Rough-In Valve Body | Delta MultiChoice Compatible, Brass, 3-Port 1/2"

Upgrade your shower with flexible, behind-the-wall versatility

The OYIMNB R10000-UNBXHF Universal Shower Rough-In Valve Body is designed to simplify bathroom refreshes by letting you upgrade your shower trim without altering existing behind-the-wall plumbing. It pairs with Delta MultiChoice trim families from the 13/14 Series, the 17 Series, and the 17T Series, giving you a wide range of style and function options without a full remodel.

This valve is built for practical versatility. It features 1/2-inch universal inlets that accept common piping methods, including copper, iron pipe, PEX, or CPVC adapters. This broad compatibility helps you connect to your current plumbing setup with fewer headaches, whether you’re renovating a guest bathroom or upgrading your master shower.

Crafted from solid brass, the valve body emphasizes durability and resistance to wear and corrosion, providing a solid foundation for your shower system as it ages. The rough-in valve is sold separately from trim kits and cartridges, giving you the freedom to choose a trim style and function that best suits your space and preferences.

Installation is designed to be straightforward. A square plaster guard helps with accurate alignment behind the wall, while a pressure test cap supports safe system testing before the final trim is installed. These elements contribute to a cleaner, more confident installation process for both DIYers and pros.

Two practical ways this rough-in supports your project

• Upgrade without behind-the-wall changes: swap in compatible Delta MultiChoice trims to refresh your shower’s look and function.
• Customize function with confidence: choose a single-function, dual-function, or thermostatic dual-function trim later, depending on your needs.
