Modern outhouses are made from brick, concrete or wood and can even be ordered online in plastic or nylon models. Many people are choosing to purchase an outhouse as an accessory for their backyard. The inside of an outhouse is usually made of wood and consists of a wooden bench with holes cut into it for seating purposes. Some outhouses provide the option of having more than one size hole for people of different sizes. Outhouses can be ordered online for between $150 and $800. There are outhouse kits available for those who prefer to do-it-themselves when it comes to designing the outhouse. A new addition and great alternative to the outhouse is called the composting toilet which requires no water and transforms the waste into hygienic fertilizer. These forms of outhouses range from $1,200 to $1,500 and can be purchased online.
