We moved into a new house that has a glacier bay toilet and the toilet seat did not fit correctly. Went to Home Depot and was told all round seats are the same size,so we bought one and it didnt fit. Did some research and there was indeed a round toilet seat by glacier bay that was about an inch longer. Special ordered it and it did not fit. Called the consumer line and they cant find the right part because the model has been discontinued (2015 toilet). So on Monday I will call Niagara, the parent company and see if they have the right size toilet seat. User's recommendation: Better to go with a different brand.
