2. A drainage channel as claimed in claim 1 wherein the position of the penetrative fastenings through the planar flanges, the floors and walls allow for waterproofing and floor finishing to be applied to the building floor over the planar flanges and at least in part down into the upwardly open channel.

3. A drainage channel as claimed in either of claims 1 or 2 wherein the drainage channel is formed from a thin walled material comprising: a metal sheet folded and formed, or a plastics material, moulded or extruded. 5

4. A drainage channel as claimed in any one of claims 1 to 3 wherein on the upper most periphery of the upwardly open channel, a third one of the sides adjacent the first one and/or the second one of the sides has a substantially planar flange extending outwardly or upwardly therefrom; and/or a fourth one of the sides adjacent the first one and/or the second one of the sides has a substantially planar flange extending 10 outwardly or upwardly therefrom.

5. A drainage channel as claimed in claim 4 wherein: the substantially planar flange of the third one of the sides is joined together to the substantially planar flange of the first 15 one and/or second one of the sides; and/or the substantially planar flange of the fourth one of the sides is joined to the substantially planar flange of the first one and/or second one of the sides.

6. A drainage channel as claimed in any one of claims 1 to 5 wherein the first one of the 20 sides and the second one of the sides are parallel and opposed to each other.

7. A method of installing a drainage channel adapted to receive fluid from a building floor and drain it to a waste outlet, comprising steps of, providing an upwardly open channel having a lower most floor portion and about 25 the floor portion are sides to fluidly enclose and define the upwardly open channel, on an upper most periphery of the upwardly open channel a first one of the sides has a substantially planar flange extending outwardly therefrom, and on the upper most periphery a second one of the sides has a substantially planar flange extending outwardly or upwardly therefrom, and a waste aperture in the floor portion to allow draining of the 30 fluid from the upwardly open channel to the waste outlet when fluidly connected thereto, locating the drainage channel into an aperture in the building floor and securing the planar flanges to an upper presenting surface of the floor, and/or surrounding walls respectively using penetrative fastenings through the planar flanges and into the floor and/or walls to hold the drainage channel in place, and the drainage channel requires 35 no support from below, it is only secured in place by the planar flanges, fluidly connecting the waste aperture to a waste outlet of the building, applying waterproofing at least to the building floor over the planar flanges and at least in part down into the upwardly open channel, laying a building floor finishing at least to an upper periphery of the upwardly open channel, and locating a grate into the upwardly open channel, the grate being supported from 5 the floor portion via upstands unitary with, and extending from, a lower portion of the grate, adjusting the grate height via a height of the upstands to have an upper surface of the grate substantially at a desired height relative an upper surface of a finishing of the building floor, 10 such that the drainage channel is located in the building floor for removal of fluid therefrom to the waste outlet.
