For bathroom locks, the spindle size is crucial. We always use 8 mm, which fits standard residential locks. The mechanism works with a turning knob on the inside and an indicator on the outside. When installing, ensure the spindle fits perfectly squarely into the lock; this prevents play and ensures smooth locking. Always match with door handles of the same style, and don't forget your hinges!
Frequently asked questions about Bathroom and toilet door fittings
What's the difference between toilet door hardware and a standard door handle?
A toilet door handle set with a shield has a rotary knob (available/occupied set) that allows you to lock the door from the inside. A standard door handle lacks this mechanism, and the door cannot be locked.
What does the 8 mm pin size mean for toilet fittings?
The pin is the metal pin that connects the knob to the lock. At Lavuzo, 8 mm is the standard size. In older homes or with specific foreign locks, 5 mm or 7 mm is sometimes used; so check this before ordering.
How do I properly install the free/busy indicator?
Insert the pin through the lock and slide the knobs on. Tighten the Allen screws firmly on the flat side of the pin; this prevents the knobs from rattling or loosening over time.
How do I determine if my lock is suitable for a toilet lock?
Check if your mortise lock has an additional square hole below the door handle hole. The center-to-center distance between these two holes determines which door hardware you need. In the Netherlands, 63 mm (WC63) is the standard.
What if my center-to-center distance is longer than 63 mm?
No worries! In that case, choose door handles on a rosette combined with a separate toilet lock on a rosette. Because you install these components independently, this system fits almost any lock.
