Bathroom Lighting Safety Questions Checklist

Run the shower as the household normally uses it and note every surface that ends up wet, including the ceiling above and the wall opposite.

Spray travels further than owners expect, particularly from a fixed head in a small enclosure, and the evidence is easy to gather.

Note where water lands around the basin during ordinary washing, including the wall behind and anything sitting on the shelf beside it.

Basin splashing is constant and gentle, which is why it is forgotten when lighting positions are chosen.

Record how far water reaches over the edge of a bath when someone gets in and out, and note if children are the main users.

Family bathing wets a much larger area than adult bathing, and that difference is worth stating explicitly.

Note how the room is cleaned, particularly whether walls or the enclosure are rinsed down or sprayed rather than wiped.

Cleaning routines put water in places normal use never reaches, and the electrician should hear about it.

Photograph the room while these surfaces are still wet, so the record is evidence rather than recollection.

A photograph of a genuinely wet wall communicates more in a site conversation than any description will.

How any position is judged against water is for a qualified electrician to determine against the requirements that apply where you live.

Note where steam collects first after a hot shower, and which surfaces mist over before the rest of the room does.

The mist pattern shows where warm wet air gathers, which is exactly what the electrician needs to hear about.

Record how the room clears after bathing — whether a window is opened, an extract fan runs, or the door is simply left ajar.

A room that clears slowly asks more of every fitting in it, and the household routine is the only reliable evidence.

Look closely at the existing fittings for discolouration, marking, misting inside a diffuser or corrosion at the edges, and photograph what you find.

The condition of what is already there is the most direct evidence of how demanding this particular room is.

Ask the electrician what makes a fitting appropriate for this room and this position, and write down the answer in the words you were given.

Owners often shop before asking, and asking first keeps the choice inside what is actually appropriate here.

Whether any fitting is appropriate for a bathroom position must be determined by a qualified electrician, not selected from a showroom description.

Note whether ventilation is being changed as part of the work, and raise lighting and ventilation together rather than separately.

The two are usually installed by the same person and affect each other, yet owners tend to discuss them apart.

Write down who uses the mirror and for what, from shaving to contact lenses to making up, and note where each person stands.

These tasks want light from different directions, and naming them prevents a single overhead fitting being asked to serve all of them.

Stand at the mirror with only the existing light on and note the shadows across your eyes, nose and chin.

Light from directly above the head is the reason most bathroom mirrors are unusable for close work, and it is easy to observe.

Note the range of heights of the people who use this mirror, including children standing on a step, and record it for the discussion.

Mirror lighting suited to one height often misses another entirely, and households rarely mention children at this stage.

If a mirror with integrated light is being considered, ask the electrician what supplying it in this position would involve.

An integrated mirror is an electrical item as well as a fitting, and it changes what has to be arranged behind the wall.

Supply, switching and position for any lit mirror or cabinet must be arranged through a qualified electrician before walls are closed.

Note whether anyone judges skin tone or makeup at this mirror, and record that the colour of light there matters more than elsewhere.

Colour is the complaint that arrives after everything is finished, when it is hardest to do anything about.

Mark on a sketch any position where light is wanted directly above a bath or within a shower enclosure, and take that sketch to the discussion.

Naming these positions early lets the electrician rule them in or out before the rest of the scheme is built around them.

Ask what may be used in each of those positions before looking at any fitting, and record the reply against the sketch.

What may occupy a position above a bath or inside an enclosure is determined solely by a qualified electrician against local requirements.

Note how the enclosure glass and any screen would reflect a fitting, and whether that reflection lands in anyone's eyes.

Wet glass reflects far more strongly than dry glass, which is not obvious when the room is being planned dry.

Note whether the floor of the shower and the step in and out are clearly visible when only the main light is on.

Seeing where you are putting your feet in a wet room is a practical concern worth raising as its own point.

Ask how a fitting in these positions would be reached later for cleaning or replacement, and by whom.

Positions over a bath are awkward to reach for anyone, and knowing that in advance affects which are worth having.

Any later access to a bathroom fitting for cleaning or replacement should be arranged with a qualified electrician rather than attempted from the bath.

Write down who uses the bathroom during the night, and whether they come from a bedroom, a landing or a stair.

The route matters as much as the room, and it is the part usually left out of the lighting brief.

Note whether the current light is uncomfortably bright when the room is entered at night, and what people do about it now.

Households invent workarounds such as leaving a door open or not switching on at all, and each one describes a missing setting.

Record that a low night-time setting is wanted, and describe what still has to be visible at that level rather than how bright it should be.

Describing what must be seen keeps the request usable, since brightness described in words means little to anyone else.

Note whether bathroom light spills into a bedroom or landing when the door opens, and who that disturbs.

Light escaping under or around a door is a genuine household problem and is easily addressed if raised early.

Record whether children or older members of the household use the room alone at night, and mention that in the discussion.

Who uses the room unaccompanied changes what the professionals will suggest, and they cannot know unless told.

Where anyone using the bathroom has particular mobility or sight needs, discuss the arrangement with a professional advising that person.

Note how the light is switched at the moment, where that switch sits and which hand reaches it while carrying something.

The existing arrangement is a starting point everyone can see, and its faults are the clearest thing to describe.

Confirm locally what applies to switching arrangements in a bathroom rather than assuming what you have seen elsewhere is possible here.

Requirements differ between places and properties, and this is not something to settle from memory or from another home.

What switching arrangement is acceptable in a bathroom must be confirmed with a qualified electrician against the requirements that apply where you live.

Note which way the door swings and whether the switch position would be behind the door as it opens.

A switch behind an opening door is reached awkwardly every single time and is fixed only before the wall is finished.

Write down which parts of the bathroom lighting you would want to switch separately, and which you are happy to have come on together.

Separation is a decision for the design stage; afterwards it usually means opening the wall again.

Note that switches in this room are operated with wet hands, and raise the finish and position of any control in that light.

Everyday wet-handed use is the practical reality of a bathroom control and is rarely mentioned when one is chosen.

Write down everything that currently starts when the bathroom light is switched on, including any fan, heater or heated mirror.

Households often do not realise several things share one control until they try to change one of them.

Note whether the fan running with the light is a problem at night, and who it disturbs.

This is one of the most common bathroom complaints and is far easier to discuss before the arrangement is rebuilt.

Record any heated mirror, heated floor or towel warmer in the room and whether its control sits near the light switch.

Grouped controls in bathrooms confuse guests and children, and the layout is worth agreeing deliberately.

Decide which of these you want to control independently in future and write that down as a request rather than an instruction.

Stating the outcome you want leaves the method to the electrician, which is where it belongs.

How lighting, ventilation and heating controls are arranged and supplied is for a qualified electrician to determine for your installation.

Ask how each of these can be turned off completely when needed, and where that control would sit.

Knowing how to shut something off matters most in a room where water is present, and the answer should come from the electrician.

Bring the agreed positions of every fixture, including the basin, bath, enclosure and any cabinet, since lighting depends entirely on them.

Lighting positions cannot be settled while the fixtures are still moving, and the sequence is often the wrong way round.

Gather the supplier information for any mirror, cabinet or fitting already chosen, and hand it over rather than describing it.

The electrician needs what the maker says about the item, not the owner impression of it.

Note what the walls are made of where fittings and controls are wanted, and mention any that are tiled, boarded or newly built.

Wall construction affects what is possible and where, and owners usually know more about it than they think.

Ask which bathroom lighting decisions must be final before walls are closed, and write that list down beside your own list of outstanding choices.

Knowing which decisions are urgent focuses attention on the ones that genuinely cannot wait.

When each decision must be final depends on how the work is being carried out and should be confirmed with the professionals doing it.

Keep a written note of what you were told, by whom and on what date, and store it with the rest of the bathroom paperwork.

Bathroom advice is given verbally on site more often than in writing, and it is the first thing forgotten.
