A toilet shredder allows you to create a bathroom in an environment where you do not have waste water discharge but gray water discharge is present. The most sold are the Sanitrit models. There are shredders that can be adjusted behind any horizontal outlet WC. The discharge capacity of Sanitrit allows the installation of services from the basement to the attic, bypassing obstacles. There are models that also allow to convey the water coming from the sink, shower and bidet.
