An extendable drain configured to move between a retracted position and an extended position includes a housing and a drain member. The housing includes a top, a bottom, and a sidewall including an annular stretchable sleeve. The housing defines an interior volume configured to be at least partially filled by a fluid causing the annular sleeve to stretch axially, thereby increasing a distance between the top of the housing and the bottom of the housing. The drain member includes an open top fixed to the top of the housing, an open bottom, and a sidewall extending between the top and the bottom of the drain member through the interior volume of the housing. At least partially filling the interior volume of the housing moves the drain member axially causing the sleeve to stretch, thereby increasing the distance between the top of the housing and the bottom of the housing.

A drain assembly including a shroud, a shank having a cylindrical radially inward facing surface defining an axis, a grate defining a plurality of openings, a frame positioned axially between the shank and the grate, and where the frame is configured to support the grate. The drain assembly also includes a cover removably coupleable to the drain assembly and configured to prevent material from coming into contact with the grate, where the cover includes an axial height defining an axial envelope, and where the grate is positioned within the axial envelope.

A drain has a cup with a fluid outlet to be connected to a conduit, wherein the cup accommodates a water trap. The cup has an axial channel along the circumference, the channel is open upwards and limited by a bottom, a channel wall and a cup wall. The drain further has a circumferential drain wall adapted to fit into the channel, whereby the drain wall is arranged axially movable in the channel, a casting framework arranged releasable around the outer circumference of the drain wall, the framework has a radial extension, and the drain wall has an outward radial flange at an upper end, the radial extension of the flange is equal or less than the radial extension of the framework. A method and a kit of parts for installing such a drain are also disclosed.

An adjustable floor drain apparatus includes a housing configured for positioning adjacent a drain pipe, manhole riser, or other feature, a leveling frame configured to be positioned at least partially above the housing, a grate configured to be positioned at least partially above the leveling frame and secured to the leveling frame, and a leveling member. The leveling member can be configured such that actuating the leveling member adjusts the position of the grate relative to the housing while the leveling member remains fixed relative to the housing. The leveling member can be configured such that actuating the leveling member moves the leveling member relative to the grate and adjusts the position of the grate relative to the housing.

The drain assembly also includes a cover removably coupleable to the drain assembly and configured to prevent material from coming into contact with the grate, where the cover includes an axial height defining an axial envelope, and where the grate is positioned within the axial envelope.

An adjustable drain assembly for adjusting the level and pitch of the frame so that, after installation, the frame can be adjust so that the strainer is level or flush with the finished floor surface. A retrofit kit for combining with a preexisting head already installed in a floor to provide an adjustable drain assembly is also disclosed.

A drain system includes a drain cover positionable over a drain opening in a floor. The drain cover has a sidewall extending about a periphery of the drain cover and a release surface on the sidewall tapering or sloping inwardly toward a bottom of the drain cover. The release surface is arranged to interface with a support frame configured to support and position the drain cover over the drain opening and reduce frictional and shear forces between the drain cover and the support frame during removal of the drain cover from the support frame.

Described are embodiments of a modular adjustable linear shower drain system. The drain system is customizable in overall length by cutting portions of the drain system while on-site and prior to assembly. The individual components of the system are made to an oversized, or standard, length and then cut to a desired installation size. Once cut on-site, the components are fit together forming the modular adjustable linear shower drain system. The drain system also includes a height-adjustable shower grill that can be set to match a surrounding tiled area height and angle. The shower grill height is set by adjusting screws disposed in the shower grill and which are in contact with portions of the drain system.

A drain system includes a support frame configured to support and position a drain cover over a drain opening in a tile floor. The support frame has a base portion and a wall portion projecting upwardly from the base portion to define a seat for the drain cover within the support frame. A release surface on the wall portion tapers and slopes inwardly from a top of the wall portion. The release surface is arranged to interface with the drain cover and reduce frictional and shear forces between the drain cover and the support frame during removal of the drain cover from the support frame.
