Bidets can be something of a puzzle.
Today its not so much "what's that for" but "how do I use it?". Yes it can be very handy for washing ones feet but it's really designed for sitting on and washing the lower body regions. For that reason your bidet should be reasonably close to your toilet, making it convenient and simple to move from the loo to the bidet. I have seen bathrooms where these items have been positioned on opposite sides of the room and it has been a puzzle for me to imagine how the bidet was reached and used. Actually the thoughts provoked always gave me an inner laugh.
There are two types of bidet:
The over rim spray
So called as the tap is mounted on the bidet rim nd the water sprays inwards towards the seated user. The picture shows a wall hung style which is suspended from a metal frame concealed in the wall. This one is fitted with a single lever mixer tap which has a swivel nozzel, enabling the spray to be directed side to side and up and down.
The ascending spray
On this bidet the water jet sprays upward from a nozzle on the base directly under the seated user. There are normally two tap controls, a hot and cold, with the water mixing before it sprays through. The center control on the picture is for opening and closing the waste. The photo shows a free standing bidet, mounted on the floor.
How to use the bidet.
Firstly it genuinely can be used for washing your feet, and makes a handy tool for this job, but its primary function is for intimate cleansing, particularly after using the toilet. The user sits on the bidet, facing the wall and thus can operate the tap controls. By sliding around on the ascending spray type or directing the jet on the over rim type washing those hard to get at areas can be simply achieved.
