This is an old revision of the document!
The reason they are specified is control. In a busy public washroom, taps left running waste water and drive up costs, and a self-closing gold kitchen tap removes that risk by returning to off after each use. This makes them a standard choice in settings with high footfall and many different users, where predictable, controlled water delivery matters more than the adjustability expected at home.
Predictable, controlled water is part of the picture too. Fittings that deliver water steadily and, in the case of thermostatic showers, hold a safe temperature help protect users for whom a sudden change in temperature or pressure is more than an inconvenience. These qualities are chosen deliberately for the setting rather than carried over from domestic styling.
Bathrooms in care homes and assisted settings are designed around the needs of people who may have limited strength, dexterity or mobility, and the fixtures are chosen to support safe, dignified independent use wherever possible. Ease of operation is central: taps that can be used with a light touch or limited grip, such as lever and non-concussive designs, make a real difference to how usable a washroom is.
Hospitality bathrooms carry a particular tension: they need to look good enough to impress a guest and be tough enough to survive constant, unfamiliar use. A hotel or venue bathroom might be used by thousands of different people a year, none of whom treat it as their own, so fixtures have to balance a considered look with genuine durability and easy cleaning.
Healthcare washrooms are specified to a level of detail that goes well beyond a domestic bathroom, and Health Technical Memorandum guidance is central to that. HTM documents set out expectations for water systems and fittings in healthcare premises, driven by considerations such as hygiene, water safety and the control of waterborne risk, which is why fixture choices in these settings are made carefully and to specification.
For fixtures, the practical link is that the layout and provision follow from the space guidance rather than the other way round. Once a washroom area and its expected use are set, the number and arrangement of taps, basins and other fittings are planned to suit, and durable, easy-to-maintain fittings such as non-concussive taps are commonly chosen for the heavy, repeated use a school washroom sees.
