The day before yesterday my son-in-law sat on the toilet seat lid to put on a sock and a massive crack appeared all the way down the side of the lid. I contacted CP Hart who sold it to us and they contacted Duravit, the response was as follows, which was so surprising!! (‘Given that the seat has been onsite since June 2020, should there have been a manufacturing fault, this would be become evident much sooner. Toilet seat lids are designed for hygiene purposes and are generally designed to be lightweight and are not built to support the full weight of a person.’.) Surely a toilet seat lid should be able to take the weight of a person.??? Any thoughts on this or advice?
