Purchased this toiled to do something different in the new bathroom.  I did not think about it until the toilet arrived that you cannot purchase a toilet seat just anywhere because of the unique shape.  When I went to the website to purchase additional toilet seats it was not listed.  I contacted customer service and was told the toilet seat is on back order.  I was placed on the backorder list and will receive an email when they are back in stock.  I highly recommend this toilet for the look but I would highly suggest you be proactive and purchase additional toilet seats.
