A 90° shower door hinge is commonly used where a glass door connects to a wall or a fixed glass panel at a right angle. A 180° shower door hinge is used where the door and adjacent fixed glass are arranged in the same straight line. The correct angle is determined by the glass layout, not by personal preference alone.
Selecting the wrong hinge angle can create uneven gaps, restricted movement, poor seal contact, or an installation that cannot be completed safely.
A 90° hinge works with corner-style layouts. Depending on its specific design, it may connect glass to a wall or connect two glass panels positioned at right angles.
This arrangement appears in rectangular shower enclosures, corner entries, and layouts where the fixed panel returns from a wall. The hinge body and clamping plates must match the intended glass-to-wall or glass-to-glass connection.
One 90° shower hinge referenced in our range supports tempered glass from 8 mm to 12 mm. Glass compatibility should still be confirmed for the exact hinge model before drilling or ordering panels.
A 180° shower door hinge connects an operable door to a fixed panel on the same plane. It is often selected for straight frameless shower fronts where there is no return panel at the hinge point.
Our 180-degree shower door hinge is constructed from stainless steel or brass. The listed load capacity for a single hinge is 35–40 kg, but the number of hinges must be calculated using the complete door height, width, thickness, and manufacturer’s installation requirements.
A load figure should never be used alone to approve a glass door.
The bathroom must provide enough clearance for the door to open without hitting a basin, toilet, towel rail, wall, or other glass panel. Seal position and threshold design also influence whether the door should open inward, outward, or both ways.
The drawing should identify:
Fixed glass position
Door width and height
Glass thickness
Hinge connection type
Opening direction
Handle position
Waterproof seal location
Floor and wall clearance
Glass cutouts and holes
Required closing behavior
Glass must be ordered only after hardware drawings and hole locations have been confirmed. Tempered glass cannot be safely drilled or cut after tempering.
Glass hinges clamp the panel through metal plates and protective gaskets. The gasket separates the hardware from the glass and helps distribute pressure.
Incorrect gasket placement, excessive tightening, misaligned holes, or direct metal-to-glass contact can create concentrated stress. Installation should be completed by technicians experienced with frameless shower glass.
A bulk supply of stainless steel shower door hinges should be organized by hinge angle, connection type, opening direction, glass thickness, finish, and project location.
Our bathroom hardware range includes glass hinges and clamps, Shower Door Waterproof Seals, and Shower Room Sliding Hardware. Coordinating these parts helps the installer check hinge movement and seal contact as one system.
A sample assembly should be tested before the complete project order. This is especially important when several enclosure layouts use visually similar but mechanically different hinges.
