A portable water and energy saving bathtub used in a shower room or a bathtub comprises a body liking an opened container, a step on the bottom is located beside the end wall. The other end is a flashboard gate, which includes a groove on inner faces of the container, the flashboard capable of moving is inserted into the groove until to a bottom of the groove, a water seal ring is set between the groove and the flashboard. A reducing-volume-chunk likes a cuboid has two legs sitting on the side walls of container, therefore, the reducing-volume-chunk is hanged in the container. A locking-releasing-device locks or releases the rock for the reducing-volume-chunk with the container.

A method of making a safe egress bathtub providing safe egress by reducing slide forces extended on a user's feet upon a slippery bathtub floor, wherein the formed bathtub has a limited rectangular footprint, and an optimized floor space is formed with a substantially planar base with a length and width that define the limited rectangular footprint and a front wall, a back wall, a first side wall and a second side wall integral with and extending substantially vertically upwards from the substantially planar base. Each of the front, back, first side wall and second side wall have minimal wall thicknesses to define the optimized floor space and the front wall has a substantially planar inwardly, cantilevered upper apron deck in a substantially parallel relation to the substantially planar base.

A plumbing assembly includes a tank, a bowl in fluid communication with the tank, and a re-fill assembly fluidly coupled to the tank, the re-fill assembly having at least one re-fill assembly valve and being configured to control a flow of water from the tank to the bowl. The plumbing assembly also includes at least one controller operably coupled to the re-fill assembly, the at least one controller being configured to control the at least one valve within the re-fill assembly. The plumbing assembly further includes a first sensor communicably coupled to the at least one controller, the first sensor being configured to sense a water level within the bowl, wherein the at least one controller is configured to stop the flow of water responsive to the water level within the bowl satisfying a first threshold.

Embodiments described herein include a bathtub that can include a U-shaped step saddle associated with a door assembly. The door assembly can include a hinge coupled with the U-shaped step saddle such that the door assembly can be transitioned between an open position and a closed position. The door assembly can include a catch and a latch to secure the door in the closed position.

A bath tub lifter, comprising a seat element (1), a lifting apparatus (4) for raising and lowering the seat element (1) between a lower operating end position and an upper operating end position, and a scissor lift arrangement (10) having two pairs of scissor lifts with scissor elements, wherein, in the operative state, respectively two scissor elements are coupled to each other such that they are mutually pivotable about a bearing axis.

A bath tub equipped with magnetic oscillation mechanism for refining water molecules include a bath tub and a magnetic oscillation refining mechanism for water molecules. The mechanism is primarily set around the bath tub and is capable of directly utilizing an alternating current power source or converting a direct current power source into an alternating current power source to drive the oscillation of an alternating magnetic field. This magnetic oscillation refining mechanism generates oscillations that refine and activate the water molecules within the bath tub, making them more easily absorbed by the human body. This offers benefits to the bather's skin, such as moisturizing, maintaining elasticity without tightness, and promoting smoothness and finesse.
