KOHLER K-5724-0 Puretide, Elongated Manual Bidet, Soft Close, Non Electric WHITE
This
isn't a "bog" standard seat (pardon the pun) :) It connects to the
water mains and there's a handle that acts like a tap that, when turned,
activates a nozzle which will then jet wash your "derriere" :)
In very good used condition. Please see photos.
Make sure it fits the shape of your toilet! This is the "elongated" version, mostly used in the USA.
