Device for a floor drain arranged close to a wall, comprising - an opening for the passage of water into the floor drain, wherein the device is more elongated in a first direction than in a second and a third direction (Y, Z), which are perpendicular to one another towards the first direction, wherein the first direction in the installed state of the device is parallel to the connection line from floor and wall in the region of the drain and the third direction corresponds to the vertical, wherein the opening extends in the first direction and is more elongated in the first direction than in the second direction, - at least one inclined surface (15, 20), which is an upper surface in the installed state of the device and is inclined with respect to the horizontal such that the water can flow to the opening over the at least one inclined upper surface (15, 20), - a first leg that is substantially vertical in the installed state, - a second leg that is substantially horizontal in the installed state, wherein the at least one inclined surface (15, 20), which is the upper surface in the position of use, is arranged on the second leg and wherein the opening is arranged in the second leg, - a cover, which partially covers the opening, characterised in that the device has an additional upper surface on the second leg which has no slope and runs along the edges on the end face and along the front edge of the second leg, in that the inclined upper surface (15, 20) comprises two upper surfaces which are inclined in the first direction (x) towards the opening and extend adjacent to the first leg from the edges of the uninclined upper surface on the end face towards the opening and in that the inclined upper surface (15, 20) further comprises two additional upper surfaces which extend between the uninclined upper surface and the surfaces adjacent to the first leg towards the cover, wherein the two upper surfaces extending between the uninclined upper surface and the surfaces adjacent to the first leg have, in the position of use to the horizontal, a slope in the first and the second direction (X, Y). - an opening for the passage of water into the floor drain, wherein the device is more elongated in a first direction than in a second and a third direction (Y, Z), which are perpendicular to one another towards the first direction, wherein the first direction in the installed state of the device is parallel to the connection line from floor and wall in the region of the drain and the third direction corresponds to the vertical, wherein the opening extends in the first direction and is more elongated in the first direction than in the second direction, - at least one inclined surface (15, 20), which is an upper surface in the installed state of the device and is inclined with respect to the horizontal such that the water can flow to the opening over the at least one inclined upper surface (15, 20), - a first leg that is substantially vertical in the installed state, - a second leg that is substantially horizontal in the installed state, wherein the at least one inclined surface (15, 20), which is the upper surface in the position of use, is arranged on the second leg and wherein the opening is arranged in the second leg, - a cover, which partially covers the opening, characterised in that the device has an additional upper surface on the second leg which has no slope and runs along the edges on the end face and along the front edge of the second leg, in that the inclined upper surface (15, 20) comprises two upper surfaces which are inclined in the first direction (x) towards the opening and extend adjacent to the first leg from the edges of the uninclined upper surface on the end face towards the opening and in that the inclined upper surface (15, 20) further comprises two additional upper surfaces which extend between the uninclined upper surface and the surfaces adjacent to the first leg towards the cover, wherein the two upper surfaces extending between the uninclined upper surface and the surfaces adjacent to the first leg have, in the position of use to the horizontal, a slope in the first and the second direction (X, Y).
