Washbasins and bathroom units: how should they be looked after?
A central feature of the bathroom, the vanity unit combines storage, comfort and style. However, to keep it looking as good as new over the years, regular maintenance is essential. Limescale, white marks, damp, mould or blocked pipes can quickly affect the appearance and proper functioning of your bathroom fittings.
How can you prevent white marks on a black washbasin?
White marks are particularly noticeable on a black washbasin. They are usually caused by limescale in the water, but also by soap residue and water droplets that dry directly on the surface.
The first rule is simple: don’t let water dry on the washbasin. After use, quickly wipe the surface with a soft cloth or microfibre cloth to remove any droplets. This simple routine goes a long way towards preventing limescale build-up.
For daily cleaning:
- use lukewarm water
- if necessary, add a small amount of mild soap or a neutral cleaning product
- clean with a non-abrasive sponge
- rinse thoroughly
- dry with a microfibre cloth
Black washbasins require special care as even the slightest mineral deposit becomes immediately visible.
Which products should you avoid using on a washbasin?

To preserve the appearance and finish of your washbasin, it is best to opt for gentle cleaning methods. In particular, avoid:
- scouring powders
- abrasive sponges
- steel wool
- highly acidic or strongly alkaline products
- solvents
- acetone
- products containing bleach where the manufacturer advises against their use
- drain unblockers applied directly to the surface
- steam cleaners where the material is not suitable for them
Abrasive products can cause micro-scratches, which then make the surface more prone to dirt. Certain chemicals can also damage a matt, gloss or coloured finish.
How can you prevent mould around a washbasin?

The bathroom is naturally exposed to damp. Without adequate ventilation, this damp can encourage the growth of mould, particularly around silicone seals, the tap, the washbasin top and in hard-to-reach areas. To minimise the risk of mould, adopt a few simple habits.
Ventilate regularly
After a shower or bath, leave the mechanical ventilation system running if your bathroom is fitted with one, and air the room whenever possible to quickly remove damp.
Avoid standing water
Wipe up splashes around the washbasin and on the vanity unit, paying particular attention to the areas behind the tap and around the drain.
Check the seals
Regularly inspect the seal between the washbasin and the wall. If it is discoloured, peeling or cracked, it may trap moisture: replacing it is then more effective than simply cleaning it.
Check for leaks
A small leak under the washbasin can go unnoticed for several weeks. Check the connections and the area under the vanity unit regularly.
How do you clean a washbasin trap properly?
The trap prevents unpleasant odours from the pipes from rising into the bathroom. However, it can gradually build up hair, soap scum and other deposits. Cleaning it regularly helps to minimise unpleasant odours and drainage problems.
Cleaning a trap in a few steps
Place a container under the trap
Place a basin or bucket underneath to catch any water that may drain out.
Dismantle the trap
Depending on the model installed, carefully unscrew the lower section or the fittings provided for this purpose.
Remove any build-up
Remove any hair, soap scum and other accumulated dirt.
Rinse the parts
Clean the various parts with lukewarm water and check that no deposits are blocking the flow.
Reassemble carefully
Refit the seals correctly and tighten the connections without using excessive force.
Check for leaks
Run some water and check that there are no leaks under the washbasin.
How can you extend the life of your vanity unit?

A bathroom vanity unit is exposed to water, damp and toiletries on a daily basis. However, a few good habits can go a long way towards keeping it looking its best.
Wipe up water straight away
Although bathroom units are designed to withstand the room’s damp environment, standing water should be avoided. After cleaning or if splashes occur, dry the surfaces quickly.
Use a soft cloth
For fronts, drawers and vanity tops, opt for a microfibre cloth or a soft, slightly damp cloth. Avoid abrasive sponges, which can cause scratches or damage the finish.
Do not use your bathroom furniture to store harsh chemicals
Household cleaning products, hair dyes, solvents or other potentially corrosive substances must not remain in prolonged contact with the surfaces. Any accidental splashes must be wiped up immediately.
Ventilate the bathroom
Good ventilation helps to limit the furniture’s constant exposure to a very humid atmosphere. Manufacturers particularly recommend wiping up any standing water and ensuring adequate ventilation.
Also look after the less visible parts
Remember to clean the following regularly: the insides of drawers, handles, the legs of the unit, the spaces around the plumbing, the area under the washbasin, as well as the connections and the trap. These areas are often overlooked, yet they can accumulate dust, damp and residue.
Which vanity unit should you choose to make maintenance easier?
Maintenance can also be taken into account when purchasing your bathroom unit. A wall-mounted vanity unit, for example, makes it easier to clean the floor and creates a sense of extra space. Unit with drawers, on the other hand, allow you to store toiletries easily whilst keeping your bathroom tidy.
The size should also be suited to the room and the number of users: a vanity unit measuring 60 to 80 cm is generally suitable for small bathrooms, whilst models measuring 100 to 120 cm offer greater comfort. For family use, a double washbasin can be particularly practical.
