We have a pair of holiday cottages on the farm, and toilet seats are everlastingly failing. Modern seat seem to be a/ on the small side and b/ the hinge attachment to the seat itself is by two VERY tiny screws that work loose and fall out. We have been using wooden core plastic coated seat from Wickes (and also possibly B&Q) for around the £30 mark.
Yet another one was reported to me this morning so will need repair when the guests leave tomorrow morning, and although I usually keep a spare, this one was the last spare fitted only a few weeks ago.
I have a suspicion that possibly the cheaper all plastic ones might be more robust but would welcome informed comments from the group.
