A wave pool includes a channel that includes a bottom contour with a depth that runs from a deep end to a shoal or beach. One or more three-dimensional foils are vertically arranged along at least one side of the channel, and moved against the water in the channel. Each foil has a curvilinear cross-sectional geometry that defines a leading surface that is adapted to generate a wave in water moving past the leading surface, and a trailing surface configured for flow recovery to avoid separation of the flow of water in the wave and to mitigate drag from the foil from the water moving past the leading surface.

A wave pool for producing waves having a first wave forming portion with an inclined section and a second wave dampening portion having a raised floor above a bottom chamber floor wherein the raised floor preferably has multiple openings thereon and a predetermined porosity () within the range of 0<0.5, such that as the waves travel across the wave dampening chamber, a boundary layer of energy absorbing vortices and eddies are generated above and below the raised floor resulting from water flowing up and down through the perforations, which helps to dampen the waves, and wherein the raised floor preferably comprises a padded grate drainage system consisting of multiple elongated members formed by rigid bars with foam adhered on one side thereof, which are encapsulated by a water impervious layer.

A foot tub capable of generating a bubble in use includes a base and a tub wall connected to the base, where the base and the tub wall enclose a tub chamber; an impeller is provided in the tub chamber above the base; the impeller is covered by a protective guard; a hollowed-out opening is formed in the protective guard; the protective guard further communicates with an outside atmosphere through a vent tube; a drive motor is provided in the base, and the drive motor is drivingly connected to the impeller, such that the drive motor can drive the impeller to rotate; and in response to rotation of the impeller, while water is thrown out of the protective guard through the hollowed-out opening, a local low pressure is further formed in the protective guard, such that outside air can enter the protective guard through the vent tube.

A wave pool for producing waves has a first wave-forming portion with an inclined section for causing the waves to begin breaking and a second wave-dampening portion with a raised floor with perforations extended above a bottom chamber floor. The raised floor is preferably adapted with a predetermined porosity such that a boundary layer of energy absorbing vortices and eddies is generated above and below the raised floor, resulting from water passing up and down through the openings, and the boundary layer effects on the raised floor help to dampen the waves.

A wave pool for generating surfable waves is disclosed. The wave pool includes a pool for containing water. The pool defines a channel having a first side wall, a second side wall, and a bottom with a contour that slopes upward from a deep area proximate the first side wall toward a sill defined by the second side wall. The wave pool further includes at least one foil at least partially submerged in the water near the side wall, and being adapted for movement by a moving mechanism in a direction along the side wall for generating a wave in the channel that forms a breaking wave on the sill. The wave pool further includes one or more passive flow control mechanisms to mitigate a mean flow of the water induced by the movement of the at least one foil in the direction along the side wall.

The bathtub seat is a shelving cabinet that is mounted into the wall adjacent to a bathtub. The bathtub seat has attached to it a foraminous door that swings away from the shelving cabinet towards the side of the bathtub such that the foraminous door is supported by the side of the bathtub that is distal to the side of the bathtub that that is proximal to the shelving cabinet. The bathtub seat comprises a shelving cabinet and a foraminous door.
