A bathtub closure system may include a step configured to be retrofit onto a bathtub and a plug. The step may include a first side panel, a second side panel, and an elongated platform defining a cavity configured to facilitate ingress and egress into the bathtub, and a first attachment recess extending downward from the first top surface less than an entire height of the first side panel or extending downward from the second top surface less than an entire height of the second side panel. The plug includes a body and a first attachment member affixed to the body and corresponding to the first attachment recess defined by the step. The plug cooperates with the step to form a substantially watertight seal when the first attachment member is mated with the first attachment recess and the body of the plug is positioned at least partially within the cavity.

An accelerated drain system for a walk-in bathtub with a water outlet in a side wall communicates water to a diverter valve biased to circulate the water in the bathtub and movable selectively to communicate water through a reverse check valve to a drain, the reverse check valve biased closed to prevent water flow and movable selectively to allow water flow to the drain, with a controller configured for moving the diverter valve selectively from the second position to the closed position for subsequent use of the walk-in bathtub. A method of rapid draining of a walk-in bathtub is disclosed.

A reconfigurable water distribution system for a walk-in tub bathing installation including two or more types of discharge ports for discharging water. The system includes a single motorized pump having an input connected to a suction port of the bathing installation, and an output port delivering pressurized water. A pipe system selectively connects the pump to the two or more types of discharge ports to selectively direct the pressurized water to the different ones of the types of discharge ports. The system selectively enables the bathing installation to perform a plurality of different functions using a single pump.

A multi-piece bathtub conversion kit with a bathtub having a U-shaped cut out passthrough defining a lower area that a user can more easily step over to enter a bathing area of the bathtub and use the bathtub as a shower. The kit includes a U-shaped outer insert shaped and sizable to cover the lower area of the passthrough and create a cut-to-fit passover surface over the lower area extending from an outside edge of the outer insert to an inside edge of the outer insert. The outer insert includes an outer flange joined to the outside edge of the outer insert and extending substantially perpendicular away from the passover surface. The kit also includes a U-shaped inner insert shaped and sized to be adjoinable to a cut-to-fit passover surface and thereby seal off the lower area of the passthrough from an environment surrounding the passthrough. The U-shaped inner insert is separable and distinct from the U-shaped outer insert. The inner insert includes an inner flange joined to an outside edge of the inner insert and extending substantially perpendicular away from the cut-to-fit passover surface.

An upright massage tub can be converted into a standard bathtub. The upright massage tub is designed so as users can safely and easily enter the tub in a step/sit motion, sitting themselves upright in a natural, ergonomic position (at approximately a standard chair height). This upright design is also better for user assistants, putting them in a better ergonomic position while they assist users in bathing. This upright massage tub design also includes a vertically adjustable hub, housing a water jet that can deliver a proximity source of water-jet flow.

A walk-in hot tub which can enable one or more users to walk into and out of a hot tub in a dry state may include a hot tub compartment. The hot tub compartment may have a hot tub compartment interior. A tub transfer compartment may be disposed adjacent to the hot tub compartment. The tub transfer compartment may have a transfer compartment interior. An openable transfer compartment door may provide walking access to a user from outside the tub transfer compartment into the transfer compartment interior of the tub transfer compartment. An openable hot tub compartment door may provide walking access to one or more users between the hot tub compartment interior of the hot tub compartment and the transfer compartment interior of the tub transfer compartment.

A walk-in bath comprising a sidewall and a door; wherein the door is configured to be in an open position or a closed position, the sidewall and closed door define a tub configured to hold bathing water, the door comprises a fin configured to be grasped by a bather, and the fin comprises a continuous projection positioned on a top edge of the door between a first end of the door and a second end of the door.

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.

The plug includes a body and a first attachment member affixed to the body and corresponding to the first attachment recess defined by the step. The plug cooperates with the step to form a substantially watertight seal when the first attachment member is mated with the first attachment recess and the body of the plug is positioned at least partially within the cavity.
