The Sewer Floor & Dynamic Channels

by Francesco Passaquindici | Aug 25, 2026 | system | 0 comments

The Sewer Floor follows the core modular logic of our Structural Walls: by adding and swapping just a few Dynamic Floors, Dungeon Masters can generate numerous aesthetic and tactical configurations in seconds.

The main Sewer Floor features a central intersection of wastewater channels. To this base floor, you add four Dynamic Floor corners crafted with a realistic stone slab finish. These corner pieces come in two dedicated variants:

  • Single-Pin Version: Available in 2 distinct surface textures to vary the stonework across rooms.
  • Double-Pin Version: Specifically engineered to connect directly to structural Pillars and securely lock surrounding walls in place.

Additionally, the kit includes swappable cover sections — one 100x50 mm floor and two 25x50 mm side floors. These allow you to seamlessly convert an open, toxic wastewater channel into a partial walkway or a fully paved cobblestone room with a single gesture, without tearing down walls or dismantling your layout!

"The sewers are a highly dramatic environment that creates a tense atmosphere and instills fear in any group of adventurers. A secret entrance to a necromancer's lair? A hidden subterranean escape? The sewers are home to all manner of slimy, foul-smelling horrors…"

A: Yes! The outer perimeter features standard 3DL flush connectors and OpenLOCK clip slots, allowing seamless connection between sewer channels, stone dungeons, and catacombs.
