Self Contained Systems
No space below the toilet pedestal is required.
These self contained systems are popular with weekender homes, container cabins or granny flats. Self-contained toilets are very compact with the treatment chamber inside the toilet pedestal. Capacity is somewhat reduced compared with Split Systems.
If you require a toilet for more than 4 people on a full-time basis you will need either two Self-contained toilets or to create a situation where you can install a Split System.
