Looking for bathroom door lever handles with lock

Try searching for “door handle with thumb turn lock”

It returned what I think you mean.

Another option, is a euro lock with a thumb turn on the inside. You could use a key to enter in an emergency.

Like this, only levers instead of knobs?

My text reader is struggling to interpret "“door" and searching doesn't help.

Thanks for those replies, in the end I found something suitable and the questions connected with it reveal that it is indeed what I am looking for, however they're hard to find

Domestically, there used to be these where a small lever actually physically locked the handle, but was only obviously on one of the pairs of handles and it seemed the wrong one on all the handles I looked at. I suppose had it been a pair of knobs I wanted, they would be universal, as you could arrange the pin that did the locking to work either way. No through door indication though. Maybe what you need is something that public toilets use? Now there is only me in the house, of course I have no need for this function! Brian

Certainly more user friendly than a high backed chair wedged under the doorhandle! I thought privacy were those with engaged and vacant on a little window on the other side. Brian
