40-Inch Offset Outlet Linear Drain – Solve Structural Challenges Without Costly Demolition

Stop fighting your floor joists. The SereneDrains 40" Offset Outlet is the definitive solution for luxury shower installations where a center drain is physically impossible. By placing the outlet just 2.8" from the end of the drain, we’ve eliminated the need for dangerous joist notching, expensive concrete core drilling, and plumbing relocation.

Benefits and Features

• Reduced Labor Costs: Avoid structural modifications when a joist sits exactly in the center of your shower footprint.
• High-Flow Performance: Engineered to handle 9.5 GPM (when installed against the wall)—ideal for high-end rainfall and multi-jet shower systems.
• Barrier-Free Design: Suitable for ADA-compliant, wheelchair-accessible, and "curbless" walk-in showers.
• Industrial-Grade Construction: Constructed from heavy-duty 16-gauge 304 Stainless Steel with a laser-cut electropolish finish for maximum corrosion resistance.

Structural Problem-Solving

This offset configuration is designed specifically for complex renovations:

• Center Joist Conflict: Install your drain exactly where you want it without compromising the home’s structural integrity.
• Concrete Slab Installations: Avoid the expense of jackhammering and relocating existing plumbing in 4"+ slabs.
• Modern Retrofits: Seamlessly adapt to existing side-outlet plumbing in older homes.
