Design

You may install JABSCO

Regular and Compact bowl 

manually operated marine 

toilets in both power and 

sailing craft, either above 

or below the waterline, for 

use on sea, river, lake or 

canal.
Your installation may 

discharge the waste either 

overboard (provided that 

your national and local 

regulations allow this), or 

into a treatment system or 

into an on-board holding 

tank (U.S.C.G. Marine

Sanitation Devices Type

I, II and III).

JABSCO manual toilets are 

designed specifically for 

marine use. Consult Jabsco 

Industries for advice about 

possible non-marine        

applications.

Optional re-assembly

by installer for left

hand operation.
