Types of sanitary appliances

[edit] Introduction

The Building Regulations Approved Document G: Sanitation, hot water safety and water efficiency suggests that the term ‘sanitary appliance’ means a ‘… WC, urinal, bath, shower, washbasin, sink, bidet and drinking fountain. It also includes appliances that are not connected to a water supply (e.g. composting toilet) or drain (e.g. waterless urinal).’

These appliances collect and remove waste matter. They are generally grouped into two categories: soil appliances and waste water appliances.

[edit] Soil appliances

Soil appliances remove different types of solid waste material. Examples of soil appliances include:

• Toilets or other types of water closets (such as squatting, composting, washdown, siphonic or universal).
• Bidets (either pedestal or wall hung).
• Urinals (bowl type, slab, stall, squatting, syphon jet or waterless).
• Slop sinks (found in hospitals and used for emptying and washing bedpans and urine bottles).
• Bed pan sinks (again, found in hospitals).

[edit] Waste water appliances

Waste water appliances are primarily used to collect and remove water once it has been used. Examples of waste water appliances include:

• Wash basins.
• Wash troughs.
• Sinks.
• Showers.
• Bathtubs.
• Drinking fountains.

These appliances should have a durable, smooth, easily cleaned and non-absorbent surface. They are typically made of non-corroding material, such as ceramic, china, porcelain, enamelled cast iron or pressed steel, stainless steel, glass or specially treated plastic.
