Standard Size of a 24 Cabinet
A 24 cabinet, as the name suggests, usually refers to a bathroom cabinet that is 24 inches (about 61 centimeters) wide. Cabinets of this size are very popular in small bathrooms or toilets because they are both compact and practical. The depth of a standard 24 cabinet is usually between 18 and 21 inches (about 45.7 to 53.3 centimeters), while the height is between 32 and 36 inches (about 81.3 to 91.4 centimeters).

Undermount Sinks
Bathroom undermount basins are sinks that are installed underneath a counter or worktop. Undermount basins offer a neater, smoother look to the bathroom than traditional countertop basins because all the sink edges are hidden under the counter. Not only does this make cleaning easier, but it also provides more counter space in the bathroom. Imagine the neatness of an undermount bathroom sink paired with a practical 24 cabinet, they are the perfect match.
How to Choose the Right Undermount Basin Size for 24 Cabinets
When choosing the right under-mount sink size, you need to consider the following points:
The actual space available in the cabinet
Although the cabinet’s exterior dimensions are 24 inches, its interior construction and design may limit the actual space available. For example, the cabinet’s drawers, door hinges, or interior dividers may affect the sink size you choose. Therefore, make sure to measure the interior dimensions of your cabinet and consider all possible obstacles before making a purchase.
Depth of the sink
Depth is an important consideration. A sink that is too deep may clash with the plumbing underneath. Considering that you may need to make room for plumbing, valves, and other fittings, it’s wise to choose a moderately deep sink.
Installation edge
Undermount sinks are installed in such a way that they require a certain edge under the counter to hold them in place. This means that the size of the sink you actually need should be smaller than the interior dimensions of the cabinet to ensure a solid installation.
Style and design
The style and design of your sink can affect not only aesthetics but also functionality. Consider choosing a design that coordinates with your bathroom décor and cabinet style. Also, consider the shape of the sink, such as rectangular, oval, or special designs, and whether there are additional features, such as a double-sink design.
Materials and maintenance
Different materials (such as stainless steel, ceramic, or glass) can affect not only the appearance of the sink but also its durability and maintenance requirements. Choose a material that matches your lifestyle and cleaning habits.
To summarize, for a 24 cabinet, an undermount sink with a width between 19 and 22 inches (about 48.3 to 55.9 cm) and a depth between 14 and 17 inches (about 35.6 to 43.2 cm) is ideal. However, your specific needs and the overall design of your bathroom will need to be considered in the final decision.

FAQ
What are the typical dimensions of an undermount bathroom sink?
The size of an undermount bathroom sink can vary depending on the brand and design, but typical sizes are usually in the following range:
- Width: 16 to 24 inches (about 40.6 to 61 centimeters)
- Depth: 12 to 20 inches (about 30.5 to 50.8 centimeters)
- Height (depth): 5 to 8 inches (about 12.7 to 20.3 centimeters)
How do I know what size sink to buy?
Measure the interior dimensions of the cabinet: first, make sure you know the interior width and depth of the cabinet, this will help you determine the maximum size of the sink.
Consider the installation rim: as mentioned earlier, under-mount sinks require a certain rim to be secured to the cabinet, so your sink size should be smaller than the actual interior dimensions of the cabinet.
Consider features and styles: Depending on your needs, consider whether you need a double-sink design or other special features, and choose your size accordingly.
Consult an expert: If you are unsure, consult a bathroom remodeling expert or sink supplier who can provide you with professional advice.
Should a 24-cabinet have one door or two?
For 24 cabinets, the usual design is to have one door. Since the cabinet is 24 inches (about 61 cm) wide, which is a relatively small size, a one-door design maximizes storage space and reduces the distraction of a central door post. This design not only simplifies the look of the cabinet but also makes accessing items easier.
However, there are some 24 cabinet designs that utilize two doors, especially those that focus on decorative or symmetrical designs. This design is less common in 24 cabinets, however, as it may sacrifice some actual storage space.
Overall, 24 cabinets are more commonly designed with a single door, but double-door options also exist, depending on brand, design, and personal preference.
