How the Horizontal Side Discharge Reducer Works
The ABS horizontal side discharge reducer connects directly to a standard PVC base pipe and P-trap, converting a vertical drain outlet into a horizontal discharge. This simplifies installation, reduces demolition, and lowers renovation costs—while maintaining proper slope and reliable drainage performance.
Designer Square Shower Drain Included
Paired with the reducer is a SereneDrains stainless steel square shower drain, designed to deliver both performance and refined aesthetics. The architectural decorative grate creates a modern focal point while ensuring efficient water evacuation.
Crafted from premium 304 stainless steel, the drain is corrosion-resistant and built to perform in high-moisture environments. Its low-profile, flush design provides a smooth, trip-free surface—ideal for curbless, minimalist, and contemporary shower designs.
