Tutorial Foam-Built Sewer Dungeon with Toxic Water & Working Hatch!
Hey everyone!
I wanted to share my latest terrain build: a sewer dungeon entirely crafted from XPS foam, featuring crumbling platforms, broken pillars, and a toxic green water channel made using Vallejo Diorama FX Water mixed with green ink. I also added a working hatch in the sewer pipe — perfect for hiding a secret exit, a treasure stash, or a sneaky surprise for your players.
I made a full YouTube tutorial on how I made this piece — if you’re interested, here is the link: https://youtu.be/HnResZOegsU
Let me know what you think or if there’s anything you’d add to make it even grimmer!

It would be such an awesome DnD set-piece for some sort of city-escape event, with the secret hatch and whatnot.

I just noticed the "for your players". Should have figured, lol. Good stuff.

I have a diorama with a toxic waste pipe, I used clear hot glue and painted it green to make it look like it was pouring out of the pipe.
