A toilet installed in a bathroom includes a toilet bowl and a tank coupled to the toilet bowl. The tank can contain fluid for the toilet bowl. A rear surface of the tank is flush against a wall of the bathroom such that there is no gap between the tank and the wall and a bottom surface of the tank is flush against a floor of the bathroom such that there is no gap between the tank and the floor. The tank extends longitudinally above and below the toilet bowl and laterally outward past the toilet bowl such that a first side surface and a second side surface of the tank define outermost side peripheries of the toilet.

A drain pipe structure configured for a basin, comprising a drain pipe body for water drainage, at least one connecting seat, and at least one mounting seat. The at least one connecting seat is configured to be connected to the drain pipe body to be fixed relative to an axial direction of the drain pipe body and at least one of rotation direction about an axis of the drain pipe body. The at least one connecting seat comprises a first connecting member, and the at least one mounting seat comprises a second connecting member. The first connecting member is configured to be operatively coupled to the second connecting member to enable the at least one mounting seat to operatively move along the axial direction of the drain pipe body to be fixed to a predetermined position of the at least one connecting seat along the axial direction.

A joint device for drain pipes comprises a structural tube made of a rigid material and providing structural integrity to the joint device. The structural tube defines at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for complementary sealing engagement with a pipe of a drain network. An annular seal of resilient sealing material is integrally connected to an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions for sealing engagement with a tailpiece slid downwardly into engagement with the joint device.

An intelligent drainage device includes a power supply unit, a water discharge key, drain assemblies, a motor drive unit and a control unit. The drain assembly, installed to a bathtub drain hole, includes a waterstop member, a stepping motor and a receiving tube. The receiving tube engages fixedly and oppositely the waterstop member and a power transmission shaft of the stepping motor. The control unit receives a start/stop signal from the water discharge key, then transmits the signal to the motor drive unit for controlling the power transmission shaft to drive the corresponding waterstop member to move upward or downward. In this device, with a simple touch at the water discharge key, the control unit would control the motor drive unit to activate the stepping motors so as to have all the drain assemblies at the respective drain holes to discharge simultaneously and rapidly the water inside a bathtub.

Described herein are embodiments of a drain adapter device configured as a low-profile drain that provides a dry seal between a drain base and an installed floor drain. The low-profile drain is configured to receive threaded drain gates or strainers. In some embodiments, the drain adapter device provides a low-profile drain system that includes universal receiving features configured to engage with strainers, drain gates, caps, and the like.
