Under-basin cabinet dimensions: 60, 80, 120 cm – Which one is right for you?
Adapt your dimensions to your space
The size of your bathroom directly determines your choice of vanity unit. The right size will optimise the available space while meeting your daily needs. We can help you identify the ideal solution for your layout.
Small bathroom: go for 60 cm
In a confined space, every centimetre counts. For bathrooms smaller than 4 m², a 60 cm cabinet is the optimal solution.
This size offers the perfect compromise between functionality and space saving. You get a comfortable washbasin without compromising on circulation. The space remains fluid and pleasant to use on a daily basis.
If your space is really limited, opt for a washbasin unit. With a width of 40 to 50 cm, it fits perfectly in separate toilets or very small bathrooms.
Our advice: Choose wall-mounted models that visually clear the floor and make maintenance easier.
Medium bathroom: choose 80 cm
For an area between 4 and 6 m², the 80 cm unit is the preferred choice. This size strikes the perfect balance between storage space and footprint.
You gain in comfort of use thanks to a wider basin. Storage space is significantly increased with more spacious and numerous drawers. This configuration is ideal for family bathrooms.
The advantages of an 80 cm cabinet:
- Ample worktop space for your everyday accessories
- Deep drawers for towels and electrical appliances
- Perfectly suited to family needs
Important: Allow 70 cm of free space in front of the unit for comfortable use.
Large bathroom: choose 120 cm or custom-made
The spacious bathrooms measuring over 6 m² allow for 120 cm furniture or bespoke solutions. These dimensions create luxurious and ultra-functional installations.
A 120 cm piece of furniture provides you with:
- Possibility of installing a double basin
- Ample storage space with multiple compartments
- A true aesthetic focal point in the room
Bespoke solutions enable you to:
- Precisely adapt the dimensions to your space
- Customise materials and finishes
- Configure storage according to your needs
- Integrate specific equipment
For unusual spaces (attic rooms, rooms with awkward corners), we suggest you make an appointment directly at the EXPOcenter to discuss your project. You can also use one of our online configurators to get started on your bathroom project.
Tip: In a large bathroom, leave up to 100 cm of space in front of the cabinet for optimal circulation.
The final choice depends on your floor space, but also on your habits and storage needs. A well-sized piece of furniture can transform your daily routine in the bathroom.
Comfort and practicality for everyday use
Beyond dimensions, your vanity unit must be perfectly suited to your everyday use. Ergonomics and practical features make all the difference between a simple piece of furniture and a true everyday ally. Discover the essential features that guarantee optimal comfort in your bathroom.
Suitable height: consider all users
The standard height of a vanity unit ranges from 80 to 85 cm. This size is ideal for adults of average height, allowing for comfortable use without excessive effort.
If you are taller than 1.80 m, choose a height of 85 to 90 cm to avoid bending over. Conversely, a reduced height of 75-80 cm makes access easier for people who are shorter or have reduced mobility.
Families with children can choose from several practical solutions:
- A stable, non-slip step stool
- A piece of furniture with adjustable height
- A shallow basin for easy access
For people with reduced mobility, the PRM standard recommends a maximum height of 80 cm with a clearance of 70 cm under the washbasin. This configuration allows wheelchair access while maintaining satisfactory ergonomics.
Circulation space: 70 cm in front of the unit
Leave a minimum of 70 cm in front of your furniture for comfortable use. This distance allows you to stand up without discomfort, open drawers fully and move around easily.
For a shared bathroom, allow for 90 cm of free space. This will help you avoid morning rush hour chaos!
A few points to note:
- The shower door must not encroach on this 70 cm area.
- The opening of the cabinet doors must not block the passageway.
- Other equipment (toilet, radiator) must comply with this free space requirement.
In small bathrooms, wall-mounted furniture creates a more spacious feel. Sliding doors also save the space needed for opening doors.
Optimised storage: soft-close drawers
Soft-close drawers are now an essential quality standard. This system offers several advantages:
- Silent closure without clattering
- Protection against hinge wear
- Enhanced safety for children
- Superior user comfort
Internal organisation also deserves your attention:
- Adjustable dividers for customised compartments
- Cosmetics organiser with dedicated spaces
- Non-slip mats that keep objects in place
- Modular storage boxes
The depth of the drawers plays a key role. The upper drawers (15–20 cm) are suitable for everyday items, while the lower drawers (30–40 cm) can accommodate bulkier items and accessories.
A well-organised cabinet saves you time every morning and keeps your bathroom tidy.
Style and budget: find the furniture that suits you
The aesthetics of your vanity unit determine the atmosphere of your bathroom. Once the dimensions and functionality have been defined, the choice of style transforms this space into a true everyday refuge. We assist you in this selection process, which combines personal taste and budgetary realities.
Wall-mounted furniture: the trick to visually enlarging your space
Wall-mounted furniture radically transforms the perception of your bathroom. Fixed to the wall without touching the floor, it creates an impression of lightness that visually enlarges the room.
This layout has several practical advantages. Floor maintenance becomes easier, and the open space makes it easier to move around. Small bathrooms particularly benefit from this open feel.
Aesthetically, wall-mounted furniture fits in with contemporary design codes. The height of the wall mounting, generally between 20 and 40 cm, allows you to adjust the desired visual effect according to your tastes.
Please note, however, that installation requires a load-bearing wall or suitable reinforcement. A standard plasterboard wall must be reinforced to support the weight of the loaded unit, which can reach 70 kg.
Materials and finishes: choose according to your priorities
Each material meets specific requirements in terms of aesthetics, durability and maintenance.
The lacquered finish visually enlarges the space thanks to its glossy appearance. Elegant and sophisticated, it nevertheless requires regular maintenance as marks show up easily. Ideal for well-kept bathrooms that are not used very often.
The matt finish is gaining popularity for its warm and practical qualities. Less susceptible to marks, it is ideal for families. Its contemporary look suits many styles of interior design.
Solid wood provides authenticity and durability. Teak and acacia are naturally resistant to moisture, but require specific treatment. Wood develops a beautiful patina over time, adding character to your bathroom.
PVC and composite materials offer excellent value for money. Available in a wide range of colours and finishes, they allow you to achieve the desired effect without compromising on budget. Particularly suitable for very humid environments.
