Alternatively, there are toilet seat attachments that you can purchase for much cheaper and it simply upgrades your existing toilet seats to a bidet. This means that you could have a cool water wash or a warm water wash. You can have a toilet seat that not only washes your bottom, but one that air dries you as well. Some of the available bidet toilet seats allow you to have a heated seat so that on those cold winter mornings you do not have to get a sudden chill just because nature called on you. Some are battery operated and some are the full electronic bidet toilet seat that you would normally only find in lavish hotels.
