I ordered this for my husband who has difficulties in getting out of the bath. Sitting on this seat enables him to have the water at a level to give a proper bath - but it has the height to enable him to get hold of a grab rail to pull himself up.
This is one of the few hoses you can get for single/mixer taps. I first purchased one 2 or 3 years ago and it has had constant use. I am only replacing it now because the attachment that goes on to the taps is beginning to wear a bit. I would certainly recommend this.
