Does anyone know how/where I can find the typical Swiss sliding shower handhelds that you move up and down the sliding bar by pushing down on a lever? No matter where we go in Switzerland (i.e., hotels, Airbnb, rentals) we always find the same mechanism in the shower, however, when I try to find that in the internet for our own shower I cannot find it anywhere. We have four kids and this system is by far the easiest to use for the & user-friendly, whereas the more commonly found ones with knobs (France, Luxembourg, Germany) have not served us well. Any ideas where I could start in my quest? Thanks.
