Description

COMBINED DRAIN AND VENTILATION UNIT FOR A ROUGH OPENING Known linear drains typically form an elongate recessed channel, and may be implemented, for example, along a portion of a wall or at the threshold of a shower enclosure. In some examples, linear drains are implemented within a structure at the base of a threshold, for example at the boundary between a wet room and a dry room. In such examples, when the wet room is in use, excess water, from a shower, for example, may be present on the floor of said room and begin flowing towards the dry room where it may potentially cause damage. The linear drain arranged at the boundary between these two rooms prevents this water from flowing through to the dry room. Instead, before reaching the dry room, the water flows through a cover of the drain, for example a grate, and is drained away via piping to which the drain is connected, for example to the main shower drain. Known linear drains, however, have limitations in their application due to unwanted water intrusion around the sides of the drain when located at the base of a doorway, for example. This can lead to water damage of the surrounding structure, having undesirable implications for the longevity and safety of such an arrangement. The present disclosure seeks to address the problems associated with the prior art. The invention is defined by the independent patent claims. The dependent claims define advantageous embodiments of the invention. The term "concrete", when used throughout this specification, may refer to any building material which may initially be poured as a fluid, for example a solid-liquid mixture, and then sets, cures, and/or hardens into a solid. Examples of such building materials include levelling compounds, for example cement-based levelling compounds and epoxy-based levelling compounds. These building materials may be known as pourable and/or curable building materials. According to a first aspect of the disclosure, there is provided a drain for a rough opening, wherein: the drain comprises: an imaginary width axis; an imaginary depth axis; and an imaginary height axis, wherein: a first width direction extends parallel to the width axis in a first direction; a second width direction extends opposite the first width direction, in a second direction; a first depth direction extends parallel to the depth axis in a third direction; a second depth direction extends opposite the first depth direction, in a fourth direction; a first height direction extends parallel to the height axis, in a fifth direction; and a second height direction extends opposite the first height direction, in a sixth direction; the drain further comprises: a main body comprising: a channel wall forming a channel extending in the first width direction, the channel wall comprising: first and second channel side walls extending in the first with direction; and first and second channel end walls extending between the first and second channel side walls in the first depth direction; a first side flange arranged at the first end wall, the first side flange extending further in the first height direction than the end wall; and a second side flange arranged at the second end wall, the second side flange extending further in the first height direction than the first end wall. Further: - the first side flange has a width extending in the first width direction and a thickness extending in the first depth direction, the width being larger than the thickness; - the second side flange has a width extending in the first width direction and a thickness extending in the first depth direction, the width being larger than the thickness; - the first side flange projects beyond the channel in the first width direction; - the second side flange projects beyond the channel in the second width direction; - the first side flange and second side flange are each provided with a side surface extending in the first width direction and the first height direction. Advantageously, the side flanges and the ends of the main body may allow for correct positioning of the drain relative to the vertical edges of a rough opening. The vertical edges of the main opening may comprise vertical supports of one or more building material, for example wood, metal, brick, and/or concrete. As a specific example, the vertical supports may be profiles of aluminium. This may enable the drain to be installed at an early stage of construction before a concrete floor has been poured and waterproofing completed. In one embodiment the side flanges are provided with holes for fastening the drain to the vertical supports or to a wall, for example a wall made of brick or concrete in which the rough opening is located. Optionally, the drain may comprise a front flange extending: in the first width direction between the first side flange and the second side flange; and in the first depth direction, wherein the front flange comprises an upper surface extending in the first wi
