Abstract: A commode is provided comprising a hinged seat 104 having a rim surrounded by a recess and an aperture 500 under said hinged seat leading to two rollers 402, 404. The aperture 500 is adapted to receive a pan forming cartridge containing a commode liner comprising length of flexible tubular polymer material. The rollers 402,404 have a heat sealing element thereon arranged such that, in use, rotation of the rollers draws the tubular polymer material through the rollers and creates at least one seal therein so as to form a pouch for containing a user's excrement.
