In urban fringe areas, or places where antisocial groups might be expected to congregate, some degree of vandalism might be expected. This will affect the use of materials. Wood might be deemed a fire risk; lobby areas or shelters might encourage loitering and graffiti; porcelain fittings are easily smashed. It is tempting to choose materials to withstand a bomb attack, but this can create an uncomfortable and unwelcoming design; it is better to accept some risk of damage that can be repaired
easily. Nevertheless, it is prudent to consider a range of design techniques to reduce the opportunity for vandalism, such as robust fittings, high windows, stainless steel, good-sized timber sections, and finishes that make graffiti removal easy, such as smooth wood which can be sanded or re-stained or melamine-coated panels.
There is no reason why a fairly standard internal layout should not be adopted once the best arrangement has been found to suit a particular organization. There are several advantages to this, including the ability to bulk purchase fittings and replacement fixtures, and to specify standard maintenance contracts. Visitors to the site will know that a high standard has been provided and will be well maintained.
The incorporation of a few extras into toilet block layout will also help. Baby-changing shelves can be provided in the disabled toilet so that either parent can use it. (The disabled unit usually has more space and less use, and so a fold-down shelf is easy to fit.) A large sink suitable for washing pots (subject to health regulations), boots and clothes might be
provided at larger sites.
