Replacement Hinges for Pelipal Bathroom Furniture: Choosing Moisture-Resistant Concealed Hinges

A moisture-resistant concealed hinge for bathroom furniture requires high-quality nickel plating to prevent corrosion from water vapour, and standardly relies on a 35 mm drilling diameter.

When replacing a defective or rusted hinge on bathroom furniture from brands such as Pelipal, you do not depend on expensive original replacement parts from the manufacturer. The furniture industry operates with standardised fittings. As long as the technical parameters such as cup diameter, overlay type, and mounting plate hole pattern match, any standard concealed hinge / cabinet hinge can be used as a functional replacement.

This guide explains the technical criteria that must be considered when selecting suitable replacement hinges for bathroom cabinets, mirror cabinets, and vanity units.

Key Buying Criteria for Bathroom Furniture Hinges

To ensure compatibility with the existing carcase and door, precise measurements must be taken and mechanical requirements defined prior to replacement.

1. Cup Diameter and Hole Pattern

The concealed hinge owes its name to the cylindrical recess routed into the furniture door. On almost all modern bathroom furniture, this diameter is exactly 35 mm. Measure the distance from the door edge to the edge of the cup hole (the drilling distance). This usually ranges between 3 mm and 6 mm. For securing the cup into the door, various screw hole spacings exist – most commonly 45 mm or 52 mm. Preferably choose 35 mm concealed hinges whose hole pattern matches the existing holes in your door to avoid re-drilling.

2. The Overlay Type

This is the most common mistake when purchasing hinges. The overlay type defines how the closed door sits on the carcase side wall.

• Full overlay: The door rests fully on the front face of the carcase wall. From the outside, the side wall is barely or not at all visible when the door is closed. For this, you require full overlay concealed hinges.
• Half overlay: Two doors share a single central carcase partition (typical for wide, three-door mirror cabinets). The door rests only halfway across the front face, allowing room for the adjacent door. The solution is half overlay concealed hinges.
• Inset: The door sits flush within the inside edge of the carcase. The front edge of the side wall remains completely visible when the door is closed. Inset concealed hinges are used here.

3. The Cruciform Mounting Plate and System 32

The counterpart to the hinge, attached to the inner carcase wall, is the cruciform mounting plate. In industrial furniture manufacturing, System 32 is used for this purpose. This means the rows of holes in the cabinet are spaced 32 mm apart and positioned 37 mm from the front edge. Ensure that the new mounting plate supports this grid. The height of the mounting plate (often 0 mm or 2 mm) also influences the gap between the door and carcase.

4. Material and Corrosion Protection

High humidity and temporary condensation are prevalent in bathrooms. A standard hinge made of untreated steel will rust quickly in these conditions. Look for nickel-plated steel. The nickel coating seals the metal, making it resistant to moisture.

Overview of Types and Options

Beyond pure dimensions, the mechanics and opening angle determine convenience during daily use.

The Opening Angle

For standard vanity units and mirror cabinets, an opening angle of 110° is the absolute norm. 110-degree concealed hinges / cabinet hinges provide adequate clearance to retrieve items conveniently.

Special cases require different angles:

• If there are internal drawers behind the door (common in tall units), the door must swing well clear. In this case, wide-angle hinges such as the 165-degree concealed hinge / cabinet hinge are used.
• For corner cabinets with folding doors, specific angles are required, often combinations of 135° and specialised corner hinges.

Damping Systems

Uncontrolled slamming of furniture doors leads to wear and noise. Modern fittings feature an integrated soft-close mechanism. A hydraulic oil cylinder decelerates the closing motion across the final centimetres, drawing the door gently and silently against the carcase. Replacing old, un-damped hinges with concealed hinges / cabinet hinges with damping (soft close) is straightforward when cup dimensions match and represents a significant technical upgrade.

Decision Guide: Which Hinge for Which Application?

To streamline your choice, use the following scenarios when replacing fittings on your bathroom furniture:

• If you are repairing the outer door of a standard vanity unit, then choose a full overlay concealed hinge with a 35 mm cup and integrated damping.
• If you are fitting the centre door on a three-door mirror cabinet, then you strictly require a half overlay hinge, as this door shares side walls with the outer doors.
• If your bathroom cabinet features a design where doors sit recessed between the side walls, then inset door concealed hinges are the only technically correct choice.
• If the door might hit an adjacent wall or shower enclosure upon opening, then consider using opening angle restrictors (e.g. reducing to 85°) to prevent damage.

Installation Notes for Replacement

Replacing a hinge is much like changing a drill bit in a chuck: if the mounting dimensions match, the tool brand is secondary. For removal and installation, you only need a cross-head screwdriver (size PZ2) and a folding rule or tape measure.

1. Removal: Detach the door by unclipping the hinges from the mounting plates (on modern systems) or loosening the fixing screw. Then unscrew the old cups from the door and the mounting plates from the carcase.
2. Fixing mounting plates: Screw the new cruciform mounting plates into the existing 5 mm holes in the carcase wall (System 32). If holes are stripped, use specialised Euro screws with a coarser thread.
3. Inserting concealed hinges: Press the 35 mm cup of the new hinge into the door recess. Align the hinge at an exact 90-degree angle to the door edge and secure it with 3.5 mm or 4 mm wood screws.
4. Hanging the door: Guide the hinge towards the mounting plate and press until the clip mechanism audibly engages.
5. Adjustment: Use the 3D adjustment on the hinge arm. The front screw regulates the lateral gap (side adjustment). The rear screw adjusts door depth (distance from door to carcase). The screws on the mounting plate allow vertical height adjustment of the door.

FAQ – Frequently Asked Questions About Bathroom Furniture Hinges

Can I use any hinge for Pelipal bathroom furniture?

Yes, provided the technical specifications match. Crucial factors are the 35 mm cup diameter, the mounting screw hole pattern, and the correct overlay type (full overlay, half overlay, or inset). The hinge brand is irrelevant to functionality as long as the dimensions are compatible.

Why do hinges rust in my bathroom?

Rust occurs due to a combination of high air humidity, condensation after showering, and inadequate or damaged surface coating on the metal. High-grade fittings for damp environments are made of heavily nickel-plated steel, which forms a barrier against oxidation.

What is the difference between soft-close and push-to-open?

These two mechanisms perform opposite functions. Soft-close uses a damper cylinder that brakes the door movement so it closes gently. Push-to-open (or tip-on) is an ejection mechanism for handleless furniture that pops the door open upon pressing the front. Both systems generally cannot be combined within the same hinge.

How many hinges do I need per door?

The quantity depends on the weight and height of the door. For typical bathroom cabinet doors up to 900 mm in height and weighing 4 to 6 kg, two hinges are sufficient. From 900 mm in height or a weight over 7 kg, three hinges should be fitted to prevent sagging.

How do I measure the cup diameter correctly?

Use callipers or an accurate ruler to measure the widest point of the circular recess in the door (not the metal part of the old hinge). For bathroom furniture, this dimension is usually exactly 35 mm, or more rarely 26 mm on very small wall cabinets.
