About Washer Outlet Boxes

Washer outlet boxes—also known as laundry boxes, laundry valve boxes, or laundry wall boxes—are essential components for modern laundry rooms. These recessed in-wall valve boxes neatly house washing machine shut-off valves and drain connections, creating a clean, organized, and code-compliant finish. Properly designed outlet boxes make appliance connections easier, provide protection against leaks, and improve accessibility for maintenance.

At Plumbingsell, we offer a range of washer outlet box plumbing systems in multiple configurations—including PEX, sweat, threaded, and push-fit connections. Upgraded versions, such as boxes with hammer arrestors, help prevent water hammer and protect plumbing lines. All our boxes are designed for easy installation during rough-in and meet residential and commercial plumbing requirements.

Why Use a Washer Outlet Box?

Washer outlet boxes serve several key functions in laundry installations:

• Dedicated Access — Provides a convenient location for hot and cold water shut-off valves
• Drain Accommodation — Properly houses the washing machine drain line
• Pipe Protection — Shields valves and pipes inside the wall
• Leak Prevention — Helps reduce water leaks and hose failure
• Organized Appearance — Keeps plumbing connections sealed, organized, and hidden

Compared to exposed plumbing, a recessed laundry water box minimizes clutter and enhances the appearance of finished walls, making it popular in modern home builds and renovations.
