The Insulated Toilet Seat increases your comfort during the coldest periods of the year. No more butt shock when sitting on a cold toilet seat. Its classic design replaces a standard toilet seat on your toilet inside and is easily fitted on an outhouse bench. The lid closes completely, not allowing odors to rise into the outhouse. The seat is made of polypropylene foam not Styrofoam so is very durable. It’s also easy to wash and keep clean.
