I built this 8 by 8 modern outhouse for my property. I dismantled a 1993 25 foot camper and used the toilet, vanity ,sink. shower, and windows from the camper.
Step 1: Building the floor
I studded in a 8 by 8 floor with pressure treated 2 by 8s and in between the studs i mounted the black water tank from the camper .
