The Sun-Mar Dry Toilet is made from durable fiberglass, and has a regular-sized toilet seat with a seat height of 14½" above the floor. The vent system in the Waterless Kit continuously draws air down the Dry Toilet to prevent odors in the bathroom. However, if the Dry Toilet is too high above the composter for air to be drawn down, it should be vented directly. To do this, a 3" or 4" vent pipe can be installed at the rear left or rear right of the toilet, and, if necessary, a 12-volt fan can be fitted in a section of 4" vent pipe to enhance air flow.
The Sun-Mar Dry Toilet includes a bowl liner that fits beneath the seat and can be removed for cleaning as required.
