How Many Shower Functions Can One Valve Control?

Learn how shower functions affect valve planning. Count each outlet and confirm the exact valve, diverter and operating requirements before rough-in.

Every shower function requires an outlet plan. A rain head, handheld, tub filler and body sprays may look like separate decorative choices, but they determine the valve and plumbing configuration behind the wall.

What to confirm before ordering

  • List every water outlet you want in the finished room.

How to use the plan

Confirm the valve and diverter are designed for the number of outlets.

Common mistakes to avoid

  • Review pressure, pipe and local plumbing requirements with the installer.

Before work begins

Use the specification for the exact Brassty fixture as the final reference. Confirm plumbing compatibility, finished dimensions and local requirements with a qualified installer before walls are closed or finished surfaces are altered.
