Bathroom Electrics


Whilst most people know that electricity and water don't mix well there are still a number of electrical items that can be used in a bathroom safely.

It is an important though that a professional is used as much as possible and especially when carrying out a complete bathroom renovation

The most obvious one being lighting. Bathrooms along with kitchens need good lighting, and it is essential to have proper fixtures that provide adequate illumination. Lighting can be in the form of ceiling lights, vanity lights, or wall sconces, depending on the bathroom's size and layout. We cover some further options elow too.

Due to the moisture generated in a bathroom fitting in the right type of extractor fan is very important to remove moisture and prevent mold and mildew from growing in the bathroom. More bathrooms are being fitted with electric underfloor heating or stand alone electric towel heaters, that will involve our electrician as will an electric shower if chosen.

Expanding on some of the electrical work mentioned above. When it comes to extractor fans options such as the power the inclusion of a light and importantly what triggers an extractors to start and stop mean that there will be some subtle differences and wiring and settings depending on what you choose. An extractor fan should be vented to the outside, and ideally, it should have its own switch to allow for proper usage. These can be connected to come on and off independently controlled by a switch but that is not convenient for switch off as it will require someone returning to do this. The two main options for the extractor fan switching off are by a timer or by moisture detection. With a timer extractor fan you can set this to keep on running once the switch has been turned off e.g. 3 or 5 minutes to give the extractor time to remove the moisture from the air once the item genrating the moisture i.e. the shower has stopped. The good aspect of this is that you know when the extractor will turn off but it will be a little hit and miss as to whether it has been on long enough to do a good job.

The other option of a mositure level trip off switch is a more expensive extraction unit. These may continue running for a long time if someone has had a long hot and steamy shower. It may feel that it continues running with no end in sight which can be annoying late at night when you are more sensitive to noise and trying to get to sleep. Both have pros and cons and it will be our decision on which you prefer.

Wiring up electric heating and an electric shower along with possible shaver points mean that an electrician will have plenty to do in a new bathroom. With electrical items the power of the item especially when heating is involved such as a shower or towel rack will mean that certain cables will need to be run to accomodate ghigher power levels. It is best practise to size up rather than power down, whilst this may now seem the most economical option you will be able to control the power used in your device and the option to be able to boost power when you need it will be a blessing rather than running on maximum power and feeling that your shower or heater simply isn't doing an adequate job for you in certain scenarios.

Bathroom Lighting Options


If you are upgrading your bathroom it is worth considering all the lighting options available as there are possibly more than you may think and as with any new building projects the more you get donew at the time the cheaper it will be rather than retrofittling later which will cost more and may potentially be more awkward once other fitting and fixtures are in place.

One such example is where you may want subtle lighting for a relaxing bath and don't want the hassle and mess associated with candles. We are sometimes asked if it is possible to have a dimmer switch for a bathroom. It is, however, there are certain safety regulations that must be adhered to which by using our electrician you will have peace of mind knowing that a switch with the appropriate IP rating for bathroom has been used. It is also important to note that not all types of light bulbs are compatible with dimmer switches or these may be surprisingly costly. a

There are a number of aspects to research and we can also provide guidance to on some of the folllowing bathroom lighting options:

Standard ceiling lights: nothing fancy and generally involve one lighting point from the centre of the bathroom ceiling.

Wall sconces: this is another name for wall mounted lights often fitted near or above a mirror of vanity area.

Pendant lights: As this is a hung light from the ceiling, this will generally be more of an option in period properties that have much hogher ceilings.

Recessed lighting: These are now the norm for new build properties for both kitchens and bathrooms. They are hidden in the ceiling, providing a clean and modern look and will  be dotted around the whole ceiling to povide complete coverage and are also referred to as LED downlights

Under-cabinet lighting: these can be installed under cabinets or vanities to provide lighting from a different angle.

Strip lighting: a section of these can be installed around the perimeter of your bathroom mirror, to help see facial details.

Floor lighting: These are great for larger bathrooms to add subtle ambient lighting.

Mirror Lighting: If you haven't selected a mittor with build in light we can fit lighting right above your mirror to provide illumination of the face, irrespective of the other sources of light in the bathroom.

Shower Lighting: This can even be part of an extractor fan that is waterproof, and provides directed lighting inside the shower unit or directly above it.

Feel free to discuss the options with our team but ideally try to nail this at the design stage, so wiring can be laid prior to finishing wall.

Frequently Asked Bathroom Lighting and Electrical Questions

  • What is the most popular bathroom lighting in Cardiff?

    Whilst most of the bulbs used in bathrooms are now LED, older bathrooms use halogen bulbs, and lower energy versions are still an option.

    However, an LED option is almost always selected for brightness and efficiency in a new bathroom install.  

    Multiple LED lights will be fitted into the bathroom ceiling where the budget allows. The amount and spacing between lights will ultimately be your decision, but we can advise.

    Where your budget is already stretched using LED bulbs in a central ceiling light featuring several spotlights is the second most popular option.

  • Is it better to have a pull down light switch or an outside one?

    As with most options, this depends on personal preference and budget. 

    Most new build bathrooms will have the bathroom light switch near the door on the wall outside the bathroom, whereas older bathrooms will have a cord-operated switch.

    If you are renovating an older bathroom, switching from a ceiling switch to one outside the bathroom will cost more as it will mean re-routing the electric cables through a new channel in the wall that will need plastering. If the outside of your bathroom is not planned to be redecorated soon, this may provide an eyesore on your landing until it is.

  • Do people still use a shaver point in a bathroom?

    In actual fact, they do - although these days are more commonly used to charge electric toothbrushes than shavers.
