Buying Guide: Key Considerations For Tub & Shower Rough-In Valves
- Installation type: Do you need a 3-hole, 2-hole, or universal rough-in to match your trim kit?
- Compatibility: Check inlet/outlet sizes (common is 1/2-inch) and pipe types (copper, iron, PEX) to ensure a smooth fit.
- Future upgrades: A universal valve like Delta MultiChoice can simplify future trim changes without wall work.
- Included components: Some kits include trim, cartridges, or nuts—evaluate what you already own and what you need.
- Space and layout: Three-handle systems require more back-wall space; ensure your installation cavity accommodates the valve body.
- Maintenance and serviceability: Look for valves with accessible cartridges and straightforward seal replacements.
