A tub has a wall mounted spout from which mixed hot/cold water flows into the tub below the max fill level of the tub. The spout preferably does not extend significantly into the tub and can be provided with a check valve and/or vent external to the volume of the tub.

A bathing vessel includes a base and at least one wall extending vertically from the base. The wall includes a multi-layer structure that includes a layer of acrylic material on a first layer of polyurethane material, a layer of acrylonitrile butadiene styrene (ABS) material between the layer of acrylic material and the first layer of polyurethane material, and a second layer of polyurethane material between the layer of ABS material and the first layer of polyurethane material. A wood-containing composite panel is chemically bonded to at least one of the first or second layers of polyurethane material.

The water conservation system for limiting water consumption during showering, the consumption levels being determined based on accepted international consumption standards. The system features a layered/hollow bathtub designed to include: a floatable, manual indicator; a sensor positioned in the bathtub's vertical wall; a reservoir for collecting water; and a waste water drainage outlet. Three different colors (red, yellow, and green) are associated with the floatable indicator to indicate the amount of water consumed during showering. An optional controlling valve automatically shuts off water flow, if the consumption rate is too high.

A bathtub comprises a frame structure and a tub body. The tub body is pivotally accommodated at the frame structure wherein the tub body is pivotable between a bathing position and an emptying position. The method of emptying the bathtub is distinguished in that the tub body pivots from the bathing position to the emptying position. Another bathtub comprises a frame structure and at least one tub body, the tub body being accommodated on the frame structure and wherein a drainage device is disposed in the bottom of the tub body. The drainage device comprises at least one tube extending from the drain hole of the drainage device up to beneath the tub body.

A water discharge device comprising a water discharge member formed with a slit-like discharge port and a discharge path, wherein the discharge path is formed with a reservoir chamber for holding, as reserve water, water flowing into the discharge path from its upstream side, and is formed with a constricting flow path that sends forth the reserve water in the reservoir chamber to the discharge port, and lateral surfaces on either side of the discharge path in its width direction are formed such that a path width of the discharge path spreads as approaching its discharge port side from its reservoir chamber side, and is formed such that the angle formed by an imaginary line paralleling the width direction of the discharge port and, on the lateral surfaces, a tangent line passing over the discharge port's opening rim is greater than or equal to 45 and less than 90.
