A toilet having a one piece structure, a flush valve, and a seal. The structure includes a base having a fluid channel in fluid communication with a bowl; a tank having an internal compartment; a wall disposed between the tank and the base, the wall having an opening fluidly connecting the internal compartment and the fluid channel; and a retaining structure in the internal compartment. The flush valve has a valve body including an inner wall, which is disposed in the opening and extends from a first end in fluid communication with the internal compartment to a second end in fluid communication with the fluid channel, and a locking flange extending radially outward from the inner wall, the locking flange being retained between the retaining structure and the wall in a locking position. The seal is disposed between the locking flange and one of the wall or the retaining structure.

In some examples there is provided a toilet comprising a pan and a seating surface. In some examples there is provided a toilet seat providing the seating surface. The seating surface is configured to at least partially circumscribe an opening into the pan. The seating surface is configured to incline downwards towards a front of the toilet with a substantially constant gradient of at least 5 arc degrees with respect to at least one of: a floor-abutment surface of the toilet; and a normal to a wall-abutment surface of the toilet.

An air exhaust apparatus for use in conjunction with a flush toilet system having a rinsing liquid source and a toilet bowl configured with a rinsing inlet and a waste outlet. The air exhaust apparatus having: a housing constituting a gas tight space, a flushing conduit extending through the housing and having a front portion couplable to the rinsing inlet, and a rear portion couplable to the rinsing liquid source; the flushing conduit is configured with a suction opening disposed within the gas tight space. The suction opening is fitted with a liquid flow prevention mechanism configured for preventing rinsing liquid from flowing into the gas tight space during rinsing liquid flow towards the toilet bowl through the flushing conduit. A waste conduit extends through the housing and having a front portion couplable to the waste outlet, and a rear portion couplable to a sewage line; the waste conduit is configured with a gas discharge port disposed within the gas tight space. A gas propelling unit is disposed within the gas tight space and being in flow communication with the gas discharge port and configured to selectively propel gas in direction from the suction opening towards the gas discharge port and a gas flow valve is configured to selectively propel gas in a direction between the suction opening and the gas discharge port when the gas propelling unit is active.
