Bathroom Lighting

The bathroom is the only room in the home which has strict regulations relating to the type of light fitting which is suitable. To help with decisions of what can be placed where, the room is sectioned off into four separate zones. Each zone is related to the position of the water source (e.g. bath/shower). Fittings are also given what is known as an ‘IP’ rating. This rating is followed by a number, for instance IP44. The higher this number the greater protection against water and moisture. It is always recommended that if you are unsure if about a fitting to consult a qualified Electrician.

Fittings which are suitable are enclosed, usually having a rubber seal between the glass and fitting, making them less permeable to condensation.

With the zone system now in mind you can consider the many different types and style of fitting that are available.

For a modern, clutter free effect, recessed down lights are a popular choice. These are available in different colour finishes and are suitable for zones one, two and three. Another modern style fitting are spotlight bars. These are available with multiple heads which are adjustable, allowing for the light to be directed and light-up dark corners or areas such as sinks.

There is also a wide range of flush fittings available. These are available in a wide range of finishes and are widely used in rooms with low ceilings because of there compact design. Flush fittings are also available with a choice of back plates, with low energy options available. These are a good option if fittings are to be left on for long periods.

Mirrors incorporating lighting and shaver sockets are also popular choices. These are available in different stylish designs, each offering convenience combined with modern flair.

normal domestic use.

ZONE 2
a) This is the area over the bathtub or shower tray above zone 1.
b) This is the area external to zone 1 and extends to a vertical plane 0.6M
external to zone 1 to a height of 2.25M. Protection required is the same as
