Yes you can. The supplied seat is made from a form of polystyrene and provides a very warm experience when the temperature is cold! However, we recognise that some people will prefer the look and durability of a more standard toilet seat. Try to choose a model that doesn’t have too many gaps between the seat and lid. You’ll also have to fit the ‘chute’ from the top (rather than it sliding in underneath). We can give you further advice on this subject if needed.
