The aforementioned pumping device (2) is positioned in the recess (120) of the receiver (1). ## Claims ### Claim 1 A shower installation, comprising: a shower receiver, the shower receiver consisting overall of a first part forming a shower tray and a second part consisting of a recess; and wherein the receiver has a bottom and an inner rim raised relative to the bottom, said inner rim extending along an internal perimeter of the receiver, the recess being delimited by a wall disposed above the inner rim of the receiver so that water present in the tray cannot pass over said wall and enter the recess a pumping device, said pumping device being disposed in said recess of said receiver and in a casing closed by a lid, wherein the tray includes a cup, the bottom of which cup is at a lower level than the bottom of said tray and which cup is connected to the casing of the pumping device by a first outlet pipe conveying water present in said tray to the casing, and wherein the pumping device comprises a pressure switch having a membrane that is deformable under pressure and a second outlet pipe for discharging water, the pressure-sensitive switch being configured so that the membrane is deformed and commands a supply of electrical power to the pump when a level of water, that is fed into the casing and rises, exceeds a prescribed threshold value. ### Claim 2 (depends on 1) The shower installation as claimed in claim 1, wherein said first outlet pipe consists of an outlet of the cup of the tray connected by a sleeve to an inlet of the casing. ### Claim 3 (depends on 1) The shower installation as claimed in claim 1, wherein the first outlet pipe is disposed between the tray and the casing of the pumping device. ### Claim 4 (depends on 3) The shower installation as claimed in claim 3, wherein said first outlet pipe is of oblong section consisting of two parallel rectilinear sides connected by rounded ends, the first outlet pipe having two plane faces constituting each the larger dimension of said first outlet pipe and two curved faces constituting each the smaller dimension of said first outlet pipe, said first outlet pipe being positioned with its smaller dimension perpendicular to the floor. ### Claim 5 (depends on 1) The shower installation as claimed in claim 1, wherein the recess is closed by the lid. ### Claim 6 (depends on 1) The shower installation as claimed in claim 1, wherein the lid closing the recess bears on the inner rim of the receiver. ### Claim 7 (depends on 6) The shower installation as claimed in claim 6, wherein the lid closing the recess has a lateral wall that is positioned at a distance from the wall delimiting the recess so as to leave a gap, thereby removing a risk of water getting between the wall delimiting the recess and the lateral wall of the lid closing the recess. ### Claim 8 (depends on 5) The shower installation as claimed in claim 5, wherein the lid closing the recess bears on the inner rim of the receiver. ### Claim 9 (depends on 8) The shower installation as claimed in claim 8, wherein the lid closing the recess has a lateral wall that is positioned at a distance from the wall delimiting the recess so as to leave a gap, thereby removing a risk of water getting between the wall delimiting the recess and the lateral wall of the lid closing the recess. ### Claim 10 (depends on 1) The shower installation as claimed in claim 1, wherein the casing of the pumping device is fitted with feet for damping vibrations occurring during operation of said pumping device. ### Claim 11 (depends on 10) The shower installation as claimed in claim 10, wherein the cup has an edge on which is placed a grille so as to prevent the passage of elements other than water from the tray to the cup.
