  • Chemical toilet

    A line of portable chemical toilets A chemical toilet collects human excreta in a holding tank and uses chemicals to minimize odors. These toilets are usually, but not always, self-contained and movable. A chemical toilet is structured around a relatively small tank, which needs to be emptied frequently. It is not connected to a hole in the ground (like a pit latrine), nor to a septic tank, nor is it plumbed into a municipal system leading to a sewage treatment plant. When the tank is emptied, the contents are usually pumped into a sanitary sewer or directly to a treatment plant. The portable toilets used on construction sites and at large gatherings such as music festivals are well-known types of chemical toilet. As they are usually used for short periods and because of their high prices, they are mostly rented rather than bought, often including servicing and cleaning. Aircraft lavatories and passenger train toilets were in the past often designed as chemical toilets but are nowadays more likely to be vacuum toilets. A simpler type of chemical toilet may be used in travel trailers (caravans) and on small boats. Many chemical toilets use a blue dye in the bowl water. In the past, disinfection was generally carried out by mixing formaldehyde, bleach, or similar chemicals with the toilet water when flushed. Modern formulations are nitrate-based and work biologically.

  • Washstand

    A simple marble-topped washstand A washstand or basin stand is a piece of furniture consisting of a small table or cabinet, usually supported on three or four legs, and most commonly made of mahogany, walnut, or rosewood, and made for holding a wash basin and water pitcher. The smaller varieties were used for rose-water ablutions, or for hair-powdering. The larger ones, which possessed receptacles for soap-dishes, were the predecessors of the modern bathroom wash basin, or sink. Both varieties, often of very elegant form, were in extensive use throughout a large part of the 18th century and early-19th century, eventually disappearing with the advent of modern indoor plumbing.
