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.

Seamless "Invisible" Design

Paired with the adapter is a SereneDrains stainless steel tile insert linear shower drain, designed to create a clean, seamless look by allowing the same floor tile to be placed into the drain cover. This "tile-infinity" design blends the drain discreetly into the shower floor while still providing efficient water drainage, making it ideal for modern, minimalist, and architectural shower designs. Crafted from high-quality 304 stainless steel, the drain is durable, corrosion-resistant, and engineered to support reliable drainage while maintaining a visually uninterrupted surface.

Installation is straightforward thanks to the flange body edge, which accommodates all standard waterproofing methods. The pre-slope channel, with a 2 3/4" (70 mm) width, supports optimal water flow and efficient drainage performance.

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

Benefits of a Horizontal Shower Drain Converter

Using a horizontal shower drain converter offers several important benefits, especially in remodels and low-profile shower installations:

1. Connection to Existing Plumbing

The horizontal outlet allows the new drain to connect to an existing drain pipe and P-trap that are not directly beneath the new drain location. This can minimize the need for extensive demolition and significantly reduce both the mess and overall cost of the renovation project.

2. Accessibility in Challenging Installations

In scenarios where there is no access to the space below the floor—such as slab foundations, concrete subfloors, or second-story installations—the horizontal drain outlet makes it possible to complete a project that would otherwise be difficult or impossible.

3. Enhanced Aesthetic Appeal

Horizontal shower drains provide a clean, modern look by allowing the drain to be integrated seamlessly into the shower floor, often along one side or against the wall, creating a more streamlined layout.

4. Better Slope Management

With a horizontal drain, the shower floor can be constructed with a single, consistent slope toward the drain, simplifying installation compared to center drains that require multiple slope planes.

5. Barrier-Free Design

Horizontal and side-discharge drains are ideal for walk-in showers, helping create safer, barrier-free environments for users with mobility considerations. Their design and wider intake area also make them less prone to clogging.

Drain Includes: Stainless steel channel body & tile insert 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.
