Rough-Ins are used to measure the space that you will require in order to install your Sun-Mar Composting Toilet.

For Sun-Mar Mobile users, some customers have found it helpful to make a cardboard cutout of the unit prior to purchase to ensure that the unit will fit through hatches and in the head, if you are unsure of whether or not the Sun-Mar will fit.
