How the Side Discharge Adapter Works

The horizontal side discharge outlet adapter is designed for low-profile shower drain installations and features a thick ABS plastic reducer for standard PVC base pipe and P-trap connections. It allows a vertical drain outlet to transition to a horizontal discharge, helping simplify installation, reduce renovation costs, and open up new possibilities for bathroom upgrades—especially in slab, remodel, or limited-access applications.

Paired with the adapter is a SereneDrains stainless steel designer square shower drain, engineered to provide a high-end, stylish finish to any luxury bathroom. Featuring an architectural decorative cover, this drain serves as a sophisticated focal point that complements modern shower aesthetics while ensuring superior water evacuation. Crafted from premium 304 stainless steel and available in Brushed Nickel, Satin Gold, Matte Black, and Matte White, the designer grate is durable, corrosion-resistant, and precision-engineered to maintain its stunning appearance in high-moisture environments. Its sleek, low-profile design ensures a flush, trip-free surface, making it the ideal choice for minimalist and high-concept architectural shower designs.

Available Finishes: Matte Black, Satin Gold, Brushed Nickel, Matte White.

Vertical-to-Horizontal Shower Drain Outlet Adapter Primary Benefits

• Avoid Demolition & Jackhammering: Connect a new shower drain horizontally to an existing P-trap or waste line without cutting into concrete slabs or opening up lower-level ceilings. This significantly reduces labor costs, dust, and project timelines.
• Essential for Slab-on-Grade Construction: In regions where plumbing is embedded in concrete (common in TX, FL, CA, and the Southwest), this converter allows for drain relocation or replacement entirely above the slab level.
• Enables Curbless & Low-Profile Designs: Ideal for zero-threshold, ADA, and barrier-free showers where vertical depth is limited. The horizontal exit makes modern, shallow shower pans possible without lowering the subfloor.
• Bypasses Structural Obstacles: Easily route drainage around floor joists, structural beams, or post-tension cables. This prevents the need to notch or drill through load-bearing elements, maintaining the structural integrity of the home.
• Protects Radiant Heating & Utilities: Eliminates the need to penetrate downward through floors that contain radiant heating loops, electrical conduits, or existing plumbing stacks.
• Versatile Drain Compatibility: While a favorite for wall-adjacent linear drains, this converter is equally effective for standard square or circular point drains that need to be offset from the original plumbing rough-in.
• Code-Compliant Drainage: Engineered to maintain the required slope (typically 1/4" per foot) to ensure proper flow and pass local plumbing inspections, even in tight horizontal configurations.
• Multi-Unit & Condo Ready: The perfect solution for high-rise buildings where HOA rules or structural slab requirements prohibit floor penetrations. Connections stay within the existing floor assembly or chase.

Drain Includes: Stainless steel channel body, decorative stainless steel square grate, puller key, hair trap, waterproofing membrane sheet around the drain flange, installation instructions.

Note: This side-discharge outlet adapter is also compatible with other SereneDrains linear drains and square shower drains, allowing for total design flexibility.
