The present invention provides a structure for installing bathroom plumbing, the structure comprising: a structural post provided with at least one board installed parallel to the structural post and at least one building floor installed perpendicular to the structural post, the at least one board and the structural post defining a first accommodation space together, the first accommodation space provided with a first discharge pipe, the building floor forming a downward recessed area adjacent to the structural post; at least one detachable floor panel installed at the downward recessed area of the building floor to define a second accommodation space, the second accommodation space communicating with the first accommodation space; at least one toilet disposed on the at least one detachable floor panel.

A method of manufacturing a toilet includes lowering a toilet engine guide in a manufacturing support, aligning a plurality of frame members with the manufacturing support, installing at least one toilet engine component in the toilet engine guide, coupling a toilet seat assembly to the toilet, and coupling a plurality of panels to the plurality of frame members.

A ligature resistant toilet includes a frame that surrounds a bowl assembly. The frame may be made by rotational molding to create a seamless, one-piece component. The frame includes a front surface, a left surface, and a right surface that are all connected to a top surface by a rounded transition surface. A seat assembly is defined on the top surface of the frame and includes a seat that defines a bowl opening. The frame supports a bowl assembly that is positioned within a hollow interior of the frame. The bowl assembly includes a bowl and a spray ring supported by a top surface of the bowl. Piping may be attached to a trapway of the bowl assembly and extend exterior to the frame to an exterior plumbing system.

A method of installing a toilet system on board an aircraft is generally described. The toilet system includes a base support having a right base support and a left base support, a toilet bowl, a right side support and a left side support each supporting the toilet bowl. The method comprises lowering the toilet bowl on to the base supports to at least partially engage a first locking mechanism; sliding the toilet bowl in a forward direction to engage a second locking mechanism; and inserting a first pin to couple the right base support to the right side support and a second pin to couple the left base support to the left side support in order to completely engage the first locking mechanism.

A retaining mat is suitably sized to stabilize a toilet while the toilet is being replaced or installed. The mat prevents damage to adjacent tile, carpet, wood, or other flooring during toilet replacement. The mat includes an encircling retaining lip so as to form a catch basin to receive any water which may escape from the toilet.

A toilet system configured for operation on-board an aircraft includes, according to an implementation, a toilet bowl, a left side support bracket supporting the toilet bowl, a right side support bracket supporting the toilet bowl, a control box including a first set of pins, and a harness connector configured to electrically couple the toilet to the aircraft. The harness connector includes a set of pins, where the first set of pins of the control box are configured to be connected to the set of pins included in the harness connector, and the control box is configured to determine a platform of the aircraft based on the presence or absence of a pin in the set of pins included in the harness connector.

A fixture carrier for supporting a plumbing fixture includes an upright defining a first axis, and a cross-bar coupled to the upright and defining a second axis oriented perpendicular to the first axis. The fixture carrier additionally includes an arm defining a third axis oriented perpendicular to the first axis and the second axis, a bracket removably coupled to the arm and configured to couple the arm to the upright, and a plate positioned between the bracket and the arm. The plate includes an aperture configured to receive a portion of the bracket. The plate is slidable along the aperture relative to the bracket in a direction parallel to the second axis.

A modular toilet is disclosed comprising a toilet shell and a hydraulic core. The hydraulic core module is a separate unit from the toilet shell module and may be non-symmetrical with the internal and external form of the shell. The core module comprises a toilet bowl connected to a siphon drain comprising a weir. The drain may be a vertical loop drain. The toilet shell and the hydraulic core may comprise mutual sealing surfaces. The drain may comprise openings for connection to a toilet ventilation system.

A flush toilet includes: a bowl portion; a rim portion disposed on a top edge of the bowl portion; a spout portion for spouting flush water supplied from the water supply source to the bowl portion to form a circulating current; a discharge passage for discharging waste in the bowl portion, an inlet portion of the discharge passage being connected at the bottom of the bowl portion; a sanitary washing device disposed at a rear of the bowl portion, the sanitary washing device including a nozzle for spraying flush water toward a user positioned over the bowl portion; and a skirt portion disposed to respectively cover sides of both the bowl portion and the discharge passage.
