Description
You can cut a single INNI to the desired length (between 73 3/4″ – 22″) on-site prior to installation. This gives you a precise, wall-to-wall drain channel that enables a single slope floor – ideal for large format tile.
Three ways to Install:
-In-Sight Install: This installation places the Drain Channel away from the walls in your shower.
-At-Wall Install: This installation places the Drain Channel flush against a tiled wall.
-In-Shadow Install: This installation places the Drain Channel under the wall tile. This is the least visible option.
The INNI’s internal slope maintains water flow for a fresh, clean drain. Custom brush sets (sold separately) are easily able to clean all internal surfaces. Its access panel is smaller than your phone, for easy cleaning and waste pipe access.
Once you try the INNI, you’ll never go back!
Since the INNI is a kit, all product parts and pieces needed for assembly are included in the purchase. See Installation Instructions for a comprehensive list.

The INNI Cleaning Brush Set (E6103) is custom cut to the size of your installed INNI and is used to clean all internal surfaces of the drain body and slot with ease.
The INNI Drain Coupler Kit is used to combine multiple INNI together to create a drain channel longer than 73 3/4″. Each INNI installed requires it’s own waste pipe connection.
The INNI Hot Mop Receptor is used to install the INNI directly into a 3-bolt cast iron drain body.
The Drain Channel Slot Extender is used for At-Wall and In-Shadow installations to extend the drain channel.


A single INNI Hair Trap (EILD-HT) comes with the INNI Line Drain Kit and replacement Hair Traps come in packs of 6. They are used to keep hair and debris out of your waste pipe for easy cleaning and maintenance.
The INNI Tile-In Access Cover comes with the INNI Line Drain kit and replacements can be purchased separately. The Tile-In Access Cover matches the thickness of your tile and is used to cover/access the waste pipe below the INNI drain body.
The INNI In-Sight Trim comes with the INNI Line Drain kit and replacement trims are sold as a single 36″ piece. This trim creates a clean edge and finish within the drain channel.
The INNI In-Shadow Trim (E6138-SH) comes with the INNI Line Drain kit and replacement trims are sold as a single 36″ piece. This trim enables the In-Shadow installation of the INNI Line Drain, where the drain channel rests underneath the shadow of your wall tile.
