The place of windows in the bathroom

If the room has one window only, there shall be a minimum zone of open space outside the window such as to leave adjacent to the window an upright shaft of space wholly open to the sky (with the exception of any projection permitted by paragraph 6), the base of the shaft being formed by a plane inclined upwards at an angle of 30 degrees to the horizontal from the wall at the lower window level and its sides coinciding with the following four vertical planes :

(a) an outer plane which is parallel to the wall and which 4 V

(i) is at a distance from the wall of 12 feet, or such a distance as may be required by paragraph 7 of this regulation, or (subject to a limit of 50 feet) one-half the distance between the upper window level and the top of the wall containing the window, whichever is greatest; and

(ii) has a width equal to its required distance from the wall; and

(iii) is so located that some part of it is directly opposite some part of the window, and (b) an inner plane which coincides with the external surface of the wall and which:

(i) has a width such that the product of that width and the window height equals one-tenth of the floor area of the room containing the window; and

(ii) is located wholly between the sides of the window or, where it is required to be wider than the window, is so located that it extends across the whole width of the window, and overlaps it on either or both sides; and

(iii) two lateral planes joining the correct- ponding extremities of the inner plane and outer plane. This should confirm the advice that your best friend will be your local council official.

In Inner London the situation is even more complicated: London Building Acts and London Building Bye-laws apply and enforcement is by district surveyor for structural matters and London Borough Council for sanitation and drainage. It should not be assumed that these regulations are in any way unnecessary; their origins lie in the early Public Health Acts, the introduction of which was an essential move in the improvement of conditions in the last century. They embody principles of good practice that ought to be followed, whether or not the regulations exist.
