Abstract
A vacuum toilet unit comprises a toilet bowl, an operating mechanism for the toilet function, and an outer shell enclosing both the toilet bowl and the operating mechanism. In normal use of the toilet unit, substantially all of the externally applied load exerted by a user of the toilet is carried by the shell. In order to allow service access to the bowl and operating mechanism, at least a substantial portion of the shell is removable without any substantial influence on the support of the bowl or operating mechanism.
