they are popular here in madeira, but i don't like them, they are actually more icky than inbuilt bidet toilets

i think they are not so good as the bulgarian and south east asian "butt guns" which are just a shower hose with a trigger and jet

the fittings are the same so just look for хигеничен душ or similar from bulgarian vendors and you can have this fun too, really it's just that jet and the tee joint

nothing like a clean butt hands free paper free
