A hinge assembly for a shower door comprising a first panel rotatably connected to a second panel, the hinge assembly comprising: a first hinge member having a first body portion arranged to be attached to the first panel and also having a first neck portion, the first hinge member being arranged to allow rotation of the first panel with respect to the second panel about a hinge axis, wherein at least a portion of the first body portion is arranged to be connected to the first panel so as to lie at least partially within a recessed region of the first panel, such that the hinge axis lies within a footprint of the first panel; and a second hinge member having a second body portion arranged to be attached to the second panel such that the hinge axis lies outside a footprint of the second panel, and also having a second neck portion arranged to be rotatably connected to the first neck portion to allow the rotation of the first panel with respect to the second panel about the hinge axis, characterised in that the first and second neck portions (116a, 116b) have narrower widths than the first and second body portions (118a, 118b) and are shaped to prevent the hinge members (106, 108) from colliding with each other as the panels (102, 104) rotate towards each other, the widths being measured parallel to panel width of the respective first or second panel, and wherein cooperating surfaces (114a, 114b) of the body portion and the neck portion (116a, 116b) are shaped to cooperate with each other such that, as the angle between the panels (102, 104) decreases, the cooperating surface (114a, 114b) of the body portion (118a, 118b) of one hinge member is received within a space provided by the narrowing of the other hinge member in the region of the neck portion (116a, 116b), and wherein the cooperating surface (114a, 114b) of the body portion (118a, 118b) of each hinge member (104, 106) is shaped to cooperate with a corresponding cooperating surface of the neck portion (116a, 116b) of the other hinge member (106, 104) such that water egress between the cooperating surface and the neck is substantially blocked at any angle of rotation of the panels (102, 104). a first hinge member having a first body portion arranged to be attached to the first panel and also having a first neck portion, the first hinge member being arranged to allow rotation of the first panel with respect to the second panel about a hinge axis, wherein at least a portion of the first body portion is arranged to be connected to the first panel so as to lie at least partially within a recessed region of the first panel, such that the hinge axis lies within a footprint of the first panel; and a second hinge member having a second body portion arranged to be attached to the second panel such that the hinge axis lies outside a footprint of the second panel, and also having a second neck portion arranged to be rotatably connected to the first neck portion to allow the rotation of the first panel with respect to the second panel about the hinge axis, characterised in that the first and second neck portions (116a, 116b) have narrower widths than the first and second body portions (118a, 118b) and are shaped to prevent the hinge members (106, 108) from colliding with each other as the panels (102, 104) rotate towards each other, the widths being measured parallel to panel width of the respective first or second panel, and wherein cooperating surfaces (114a, 114b) of the body portion and the neck portion (116a, 116b) are shaped to cooperate with each other such that, as the angle between the panels (102, 104) decreases, the cooperating surface (114a, 114b) of the body portion (118a, 118b) of one hinge member is received within a space provided by the narrowing of the other hinge member in the region of the neck portion (116a, 116b), and wherein the cooperating surface (114a, 114b) of the body portion (118a, 118b) of each hinge member (104, 106) is shaped to cooperate with a corresponding cooperating surface of the neck portion (116a, 116b) of the other hinge member (106, 104) such that water egress between the cooperating surface and the neck is substantially blocked at any angle of rotation of the panels (102, 104).
