asked the Secretary of State for the Home Department what is the recommended ration of bowl toilets to prisoners in Her Majesty's prisons; and in how many prisons that ratio is not achieved.

The standard for toilets in the living blocks of new closed cellular prisons is one per cell designed for one inmate. In new closed and open cubicular prisons, the comparable standard of communal sanitary facilities is based on groups of 20 or 24 cubicles, containing three or four WCs and three or four urinals, respectively. Information is not available centrally on existing ratios, which vary from prison to prison.
