The British Standard BS 6465 Part 1 1994, 'Sanitary installations. Code of practice for scale of provision, selection and installation of sanitary appliances' is being updated.
This standard acts as a recommendation for architects and others on the number and type of toilets and other sanitary facilities to be included in new buildings. There has been concern in recent years that the numbers of appliances recommended are inadequate in some circumstances, particularly for women's WCs in public buildings, and that there may be overprovision in other areas.
I am a member of the British Standards committee that is revising this standard, and we are seeking comments from those who may have data or advice on the number of WCs needed in different types of buildings.
Architects in particular often receive feedback from clients and we would be interested in hearing from your readers on whether they feel that the current recommendations are adequate, and if not, how they should be changed.
We also welcome comments on other sanitary facilities, such as washbasins, baths, cleaners' accommodation etc, and any recommendations on layout, finishes or similar issues.
