Shower

1. A shower-screen pivot device comprising:

a seating element to mount to a shower surface, the seating element having a first panel-pivot element; and

a screen-support element to support at least part of a shower screen, the screen-support element having a second panel-pivot element to engage with the first panel-pivot element, so that, when interengaged, the first and second panel-pivot elements are rotatable relative to each other about a panel-pivot axis which is parallel to a base of the seating element;

wherein the screen-support element has a depending front wall having an inner surface which engages with a sealing element interposed between the first and second panel-pivot elements.

2. The shower-screen pivot device as claimed in claim 1 , wherein at least one of the first or second panel-pivot elements includes a part-cylindrical surface, and the other of the first or second panel-pivot elements is laterally slidable on the part-cylindrical surface.

3. The shower-screen pivot device as claimed in claim 2 , further comprising, when the part-cylindrical surface is on the first panel-pivot element, a fastener-access opening partway along the part-cylindrical surface.

4. The shower-screen pivot device as claimed in claim 2 , wherein the said other of the first or second panel-pivot elements includes a channel in which the part-cylindrical surface is received.

5. The shower-screen pivot device as claimed in claim 1 , wherein the sealing element is carried by the first panel-pivot element at or adjacent to an inwardly-facing side wall thereof.

6. The shower-screen pivot device as claimed in claim 1 , wherein the screen-support element further includes a depending back wall having a shorterlateral extent than the front wall.

7. The shower-screen pivot device as claimed in claim 6 , wherein the first panel-pivotelement includes a recess to accommodate the back wall of the screen-support element.

8. The shower-screen pivot device as claimed in claim 7 , wherein the back wall is canted to be spaced from the said recess of the first panel-pivot element, when the first and second panel-pivot elements are centred relative to each other.

9. The shower-screen pivot device as claimed in claim 6 , wherein, when the first and second panel-pivot elements are centred relative to each other, the front wall is at or adjacent to a plane of the base of the seating element.

10. A shower comprising:

a shower tray;

at least one shower-screen panel;

a seating element mounted to a shower surface of the shower tray, the seating element having a first pivot element; and

a screen-support element extending along a lower edge of the shower-screen panel, the screen-support element having a second pivot element, the first and second pivot elements engaged to form a pivot axis which is parallel to a base of the seating element, whereby the at least one shower-screen panel, whilst mounted to the shower tray, can tilt from the vertical when mounted to the screen-support element, the screen-support element further having a depending front wall having an inner surface which engages with a sealing element interposed between the first and second pivot elements.

11. A method of assisting installation of a shower screen using the shower-screen pivot device as claimed in claim 1 , the method comprising the steps of:

(i) providing the shower-screen pivot device having the panel-pivot axis which is parallel to the shower surface, the shower-screen pivot device being interposed between a first panel of the shower screen and the shower surface;

(ii) tilting the first panel away from vertical whilst maintaining engagement via the shower-screen pivot device, so as to rest the tilted first panel against an upright element at or adjacent to the shower surface;

(iii) mounting a second panel of the shower screen to the shower surface; and

(iv) pivoting the tilted first panel back towards vertical via the shower-screen pivot device to enable engagement with the second panel.

12. The method as claimed in claim 11 , wherein, in step (iii), the second panel of the shower screen is mounted to the shower surface via the shower-screen pivot device or an additional shower-screen pivot device, the second panel being tiltable away from the vertical whilst maintaining engagement via the shower-screen pivot device or the additional shower-screen pivot device, so as to be restable against the upright element or an additional upright element at or adjacent to the shower surface.
