What You'll Learn

Turn off electricity in the room
The most important step to remember when changing a flat plastic bathroom light is to turn off the electricity in the room. Working with electricity can be scary, but replacing a light fixture is a DIY home improvement project that you can handle. Before you begin, make sure you turn off the breaker and check that the power is off. This will ensure your safety and prevent any accidents.
To turn off the electricity in the room, locate the breaker box or fuse box. This is usually located in the basement, garage, or a closet. Once you have found the breaker box, look for the breaker that controls the bathroom circuit. It may be labelled, or you can turn off the main breaker to cut power to the entire house. Flip the breaker switch to the off position to cut power to the bathroom.
If you are unsure whether the power is truly off, you can test it using a voltage tester. Voltage testers are available at most hardware stores and are an essential tool for any DIY enthusiast. They are relatively inexpensive and easy to use. Simply touch the tester to the wires in the light fixture to check for any live voltage. If the tester lights up or beeps, there is still power running to the fixture, and you will need to double-check your work.
Once you have confirmed that the electricity in the room is off, you can safely begin working on replacing your flat plastic bathroom light. Remember to take your time and follow the necessary safety precautions to ensure a successful and accident-free project.

Use a screwdriver to twist off the light cover
When replacing a light bulb, the first step is to remove the light cover. If you are dealing with a flat plastic bathroom light, you may need to use a screwdriver to twist off the light cover.
First, identify any screws holding the light cover in place. If there are screws, you will need to use a screwdriver to remove them. Be sure to turn off the electricity in the room before you begin. Flathead screwdrivers are useful for removing stubborn screws. Place a rubber band over the screw head and try to unscrew it through the rubber band. You can also try tapping the side of the screw with a hammer at an angle to get it to unscrew. If the screw is painted over, use a thin screwdriver or a knife point to dig out the paint.
If there are no screws, look for a groove or notch at the connection between the light cover and the fixture. You can slot a screwdriver into this groove and twist it to remove the cover. If there is no groove, try to slip your finger between the light cover and the fixture to feel for any metal parts. If you find a small metal protrusion, try to pull, push, or move it sideways to see if it will release the cover. If you find a slit, you can use a screwdriver to prise the cover off.
If you are still unable to remove the light cover, you may need to apply more force. Try using a wide screwdriver in the slot between the base and the cover, and rotate the screwdriver to prise off the cover. You can also try using a coin to twist off the cover.

Disconnect the light fixture
Disconnecting the light fixture is a straightforward process, but it requires careful attention to safety. Before you begin, ensure that you have turned off the electricity in the room you are working in. This is the most important step to remember when working with electricity.
Once the power is off, you can start by loosening the screws that hold the fixture in place. Depending on the fixture, there may be two or more screws. Loosen them enough so that you can twist the fixture and remove it from the ceiling.
If your fixture is held in place by a spring mechanism, as some plastic bathroom light covers are, you may need to use a flat-head screwdriver to gently prise the fitting away. You may need to work the screwdriver around the fitting to loosen it. Be careful not to damage the ceiling or the light fixture itself.
After removing the fixture, you will need to disconnect the wires. Take a picture of the wiring first, so you know how to reconnect the new fixture. Then, tug on the wires to ensure they are still connected, and carefully disconnect them.
Now that the fixture is disconnected, you can dispose of it and prepare to install your new light fixture. Remember to take appropriate safety precautions and consult a professional if you are unsure about any part of the process.

Remove the old light bulb
Before beginning, ensure that the electricity in the bathroom is turned off. This is the most important step to remember when replacing a light fixture.
Now, to remove the old lightbulb, you must first access the bulb by removing the light cover. If the light cover is made of plastic, try twisting it with a 2p coin—this should cause the cover to pop open. Alternatively, you can try using a screwdriver. Slot a flat-head screwdriver into the groove between the light cover and the ceiling, and twist it to pop the cover off.
Once the light cover is off, you should be able to see the lightbulb. Depending on the fixture, you may need to undo some screws to release the bulb. Be careful when handling the bulb, as it may be fragile. If the bulb is held in place by a spring mechanism, gently work the bulb free. If it is screwed into a metal casing, simply unscrew the bulb and replace it with a new one.
If you are having trouble accessing the bulb, it may be necessary to remove the entire fixture from the ceiling. To do this, loosen the screws holding the fixture in place and carefully twist it until it comes off. With the power off, disconnect the wires and take the fixture down.

Sand and paint the wall to blend with the new fixture
Sanding and painting the wall to match your new light fixture is a great way to modernise your bathroom. Firstly, you will need to identify the correct paint colour and finish to match your new fixture. Take a chip from your wall to a paint store, where they will be able to use a spectrophotometer to analyse the chip and provide you with a precise colour analysis and sheen. You can also use smartphone apps such as Sherwin-Williams ColorSnap or Benjamin Moore's Color Portfolio to scan your wall and recommend hues.
Once you have your paint, it is important to sand the wall to ensure the paint adheres properly. Use a pole sander to quickly smooth out any imperfections and debris from previous paint jobs. Don't use anything rougher than 180-grit sandpaper, as you may leave scratches.
After sanding, clean the wall to ensure dust and dirt do not distort the colour. Then, apply a coat of primer to the wall. Once this is dry, you can start painting. Apply two coats of your chosen paint colour, allowing each coat to dry before applying the next.
By following these steps, you will achieve a smooth and cohesive finish that blends seamlessly with your new light fixture.

Frequently asked questions
If the plastic cover is fixed to the ceiling, try using a coin to twist and pop it open. You could also try squirting some glass cleaner solution around the rim of the light cover and twisting it off. If there is a groove at the connection between the black and white parts, you can try slotting a screwdriver in and twisting.
First, turn off the electricity in the room. Then, undo the two screws holding the light to the ceiling and disconnect it. You can then replace it with a new light fixture.
LED lights don't have sockets, so the bulb won't need replacing. Instead, the electronic module that converts AC power to DC power, called the "driver", may need replacing. Remove the fixture and find the driver module. Check the labelling and replace it with a new one.
If there is a gap between the light fixture and the ceiling, you may need to use some sealant to secure it. You can also use some plastic to cover the sink and counter to protect them from any mess. Sand the area lightly and use a brush to paint over your wall repair.
If you are uncomfortable working with electricity, you can always pay someone else to replace the light for you.
