A WC latch provides privacy on a toilet or bathroom door. The visible hardware usually consists of a turn knob on the inside and an occupancy indicator or emergency release on the outside. The correct choice depends on the existing lock, the spindle size, the rosette shape, and the color of your door handle.
First, check the existing lock
A WC set operates the lock but does not replace the mortise lock in the door. Therefore, check whether the door already has a bathroom lock or toilet lock. Also, measure the opening and see which spindle size the lock accepts. Deurbeslag24 offers versions with 4 × 4 mm and 8 × 8 mm spindles, among others; use the dimensions of your situation as a starting point.
Round or square WC set?
Preferably choose the same shape and finish as the door handle. A round door handle on a rosette combines harmoniously with a round WC set; with a square rosette, a square latch is obvious. The shape is mainly visual, but always check whether the rosette has enough space next to the door handle and the frame.
How to measure before ordering
- Open the door and determine which type of mortise lock is present.
- Measure the square spindle of the current WC knob or check the size in the lock's documentation.
- Measure the available space on the door leaf and its position relative to the door handle.
- Note the door thickness and compare it with the provided product information.
- Choose a color and shape that match your door handles.
Loose set or complete door handle set?
If you already have a door handle and bathroom lock, a loose WC set may be sufficient. For a new door, a complete set is often clearer, as the color and shape are then directly coordinated. Always check what exactly is included with any variant.
Common mistakes
- Ordering a 4 mm spindle for a lock that requires 8 mm, or vice versa.
- Only choosing by color without checking the dimensions.
- Confusing a WC set with a key or cylinder escutcheon.
- Assuming the mortise lock is always included.
View suitable WC latches
Compare the available WC sets and WC latches. Combine them with door handles in the same color and shape. If you are unsure about a size, send a clear photo of the lock and the measured spindle size via the contact details on the website.
