So we got a new toilet mod.
Go to your forge and create a toilet base.
Go to the workbench and use the toilet base to create 1 of 3 toilets.
Place the toilet you created on the workbench where you wish.
Upgrade the toilet using a wrench, and ONLY a wrench, and 4 short iron pipes.
Voila! Now you have a toilet that respawns loot so you can get more chances at turds for methane and fertilizer.
