The KERDI-DRAIN PVC horizontal outlet drain body — for slab-on-grade showers and renovation work where your drain line runs sideways instead of straight down. This version doesn't include corner seals, so it's the right choice when you're buying your KERDI-BAND and waterproofing accessories separately.

Horizontal outlets solve the problem of running a drain when there's no access below the slab. Instead of the outlet pointing down, it exits the side of the drain body and connects to a drain line running through the slab or alongside it. PVC construction means standard solvent-cement connection to any PVC drain pipe.

The KERDI-DRAIN waterproofing system

What makes KERDI-DRAIN different from a standard shower drain is the fleece-covered bonding flange. Every other drain on the market either relies on a compression seal or caulk at the membrane edge — both of which can fail over time. The KERDI-DRAIN bonding flange bonds into thin-set mortar the same way KERDI membrane does. Your waterproofing membrane overlaps directly onto the flange, creating a fully bonded, mechanically anchored waterproof connection at the most vulnerable point in the shower.

Who should choose this "no corners/seals" version

• Installers who buy KERDI-BAND in bulk rolls and cut their own corner pieces
• Contractors doing multiple showers who already stock the accessories
• When you need to match a specific KERDI-BAND width or use a different accessory configuration

If you want corner seals included for easier single-shower rough-in, look at the "WITH CORNERS/SEALS" version of this drain.

Pro tips

• Horizontal drains need careful slope planning: The drain body must be set level (not tilted) so the drain opening is flat on the shower floor, while your mortar bed or prefab tray provides the slope to the drain from all sides
• Pre-slope your mortar bed before setting the drain: For slab-on-grade work, pour your pre-slope first, let it cure, then set the drain body at the correct height for your tile assembly
• Mark your outlet direction before pouring: Once the drain is set in mortar, you can't rotate it — make sure the horizontal outlet is pointing toward your drain line rough-in before committing
