The present invention provides a structure for installing toilet piping comprising: a structural post defining a first accommodation space at a periphery thereof, the first accommodation space being provided with a first discharge pipe; at least one detachable floor panel defining a second accommodation space therebeneath, the second accommodation space communicating with the first accommodation space; at least one toilet disposed on the at least one detachable floor panel; and a second discharge pipe having one end connected to the at least one toilet and the other end connected to the first discharge pipe and disposed in the second accommodation space. The present invention further provides a method for installing toilet piping.

The flush toilet of the present invention includes a bowl which receives waste; and a discharge trap conduit which is connected to a lower portion of the bowl and extends to a discharge opening connected to an inlet of an external discharge pipe and a part of which stores sealing water. The discharge trap conduit includes: an ascending conduit which ascends rearward from the lower portion of the bowl; and a descending conduit that descends from a downstream end of the ascending conduit to the discharge opening. The descending conduit includes a bottom surface on the rear side of the discharge opening and a guiding portion formed on the bottom surface which guides the wastewater flowing horizontally from the bottom surface toward the discharge opening to be directed to either a left or right side of the center of the discharge opening.

The modular toilet flange may be a fitting that mounts a toilet to a floor and directs effluent from the toilet to an outflow pipe. The modular toilet flange may comprise a flange body and an inner ring. The flange body may couple to the floor and to the outflow pipe. The inner ring may be a circular depression in the flange body surrounding an open center of the flange body. A pair of bolts extending downward through the toilet may couple to the inner ring by engaging the inner ring. During installation, the toilet may be operable to rotate above the flange body to any angle and still engage the inner ring, thus eliminating a need for a specific alignment of the toilet with mounting bolts extending upwards from a flange.

A toilet seal for sealing between a plumbing fixture discharge and a waste drainpipe outlet is described. The toilet seal comprises a flange member having an inwardly extending flexible lip. A flexible sleeve extends downwardly from the flange member. The toilet seal further includes a compressible member having an upper surface disposed adjacent to a lower surface of the flange member. The compressible member further has a lower surface and a plurality of ridges extend downwardly from the lower surface of the compressible member.

An analytical toilet is disclosed. The toilet includes a bowl for receiving excreta, a mechanism that uses a consumable for analyzing a sample of excreta, a storage structure for storing the consumable, a sensor that detects at least one property of the consumable, and a processor that generates an alert when the property is outside a predetermined parameter. The property the sensor detects can be used to determine at least one of the identity of the consumable, the quantity or supply of the consumable, or a property related to the suitability of the consumable.

A closet flange configured to secure a toilet to a drain pipe. The closet flange includes a body portion and a flange portion. The flange portion extends radially outward from an upper end of the body portion. The flange portion comprises at least one slot and a shoulder. The at least one slot extends along the flange portion from a receiving end to a retaining end. The at least one slot has an opening that extends from the receiving end to the retaining end. The shoulder is positioned below the opening of the at least one slot and extends from the receiving end to the retaining end. The shoulder includes a support surface that extends at an angle offset from the upper surface of the flange portion.
