Bathroom Lighting needs some consideration. It may be the smallest room in the house but we spend quite a bit of time in the Bathroom.
Bare bulbs in pleated shades and pressed glass bulkhead lights should be a thing of the past.
Downlights can be used in all locations (including the shower),
Semi-flush and flush fittings can illuminate the ceiling as well as the walls and floor and you can illuminate
bathroom mirrors and
cabinets with lights above, beside or even behind the glass and have
shaving mirrors that are backlit and fog free.
We suggest that you start by looking at what lighting is present in your bathroom already. Is it bright enough? Does it create shadows? If you
apply cosmetics in your bathroom do the results look as good out in daylight?
Think about having more than one light in your bathroom. A single fitting in the centre of the room will give good illumination to the centre of the room but not much else. The
bathroom mirror deserves special attention and a
wall light either side will provide good illumination of the face. Alternatives include
recessed lights above the mirror or a
strip of light over the mirror. For best results why not consider a
mirror or
bathroom cabinet with lighting built in. Tasks like applying makeup,
shaving, and styling hair are much harder to accomplish with a poorly lit vanity unit. In this area, good colour-rendering lights are necessary to enable you to see yourself in a natural light while reducing shadows on your face. When light shines only from above or behind, you will see unsightly dark shadows under your eyes and the texture of your skin will be accentuated. Frontal lighting is necessary to reduce both contrast and shadows.
Start by thinking about how much light is required. If you currently have a 100w lamp in situ you may want to use 4 x 50w
downlights or 4 x 35w
downlights to create similar light levels. You will need more
recessed fittings because Halogen lamps have a reflector built in and have an intense beam whereas a 100w bulb gives out light in all directions. If you put in too much light into a room you can always lower the wattage of the lamps used.
Dimming your
bathroom lighting is now an option with a
pull-cord dimmer. This will let your bathroom be bright and invigorating in the morning and soft and subdued in the evening.
Bathroom
wall lights, typically one on each side of the
mirror, provide even lighting for both sides of your face. In addition to lighting for the vanity mirror, good general lighting is of maximum importance. A
ceiling fixture is a
good idea for general lighting and many modern styles are available allowing your bathroom decor to be as unique and personally yours as any area of your home.
Some care needs to be taken when choosing bathroom lighting as the regulations are strict concerning the type of light you can use.
The following information is a guide to help you understand what fittings can be placed where. This is not an installation guide and reference should be made to the IEE Wiring Regulations (16th Edition) or contact a qualified electrician.
Zone O is inside the bath or shower itself. Any fitting used in this zone must be low voltage, (max 12v) and be rated at least IP67 which is total immersion proof.
Zone 1 is the area above the bath to a height of 2.25m from the floor. In this zone a minimum rating of IP44 is required. If the fitting is 240v a 30ma residual current device (RCD) must also be used to protect the circuit in this zone.
Zone 2 is an area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor. In this zone an IP rating of at least IP44 is required. In addition it is good practice to consider the area around a wash basin, within a 60cm radius of any tap to be considered as zone 2.
Zone 3 is anywhere outside zones 0,1 and 2 (subject to specific limits) and where no water jet is likely to be used. No IP rating is required.
In addition to the above, if there is a likelihood of water jets being used for cleaning purpose in zones 1,2 and 3 a fitting rated a minimum IP65 must be used. Full details can be found in the latest copy of the IEE wiring regulations.
