The bathroom sink is an essential feature that can significantly add to the overall aesthetic of your bathroom. The basin is a core fixture that can be made in a wide selection of designs utilizing different materials, shapes, and colors to providing the necessary functionality. One of the main questions that need answering in regards to the bathroom washbasin is depth. How deep should a bathroom sink be?
A bathroom sink will typically have around 5 to 8 inches of depth. You would not want a basin to be too deep (hard to clean and uncomfortable to use) or too shallow (prone to overflow and splashes). A 5 to 8-inch depth sink will avoid those issues and are usually quite accessible to the average height of individuals.
Common Bathroom Sink Types and Sizes
You will most likely encounter two sink types at the hardware store: these are the square and rectangular-shaped basins. However, round sinks are also great options for those with a limited bathroom space as these tend to take up significantly less space than the square and rectangular basins.
Another difference between the rectangular and round-shaped basins is the depth that each provides. Square and rectangular washbasins usually have a shallower depth than the round sinks due to the difference in diameter.
Rectangular sinks will have around 19 to 24 inches of width, with the average depth between 5 to 8 inches. The round basin will usually have a diameter of 16 to 20 inches with a depth of around 8 inches.
We head on over to the more luxurious type of bathroom sink, the vanity. The vanity sink will have a standard sink depth, with the average measurement ranging from 4 to 10 inches.
Compare those numbers to the kitchen sink, which comes with a depth that ranges between 6 to 12 inches. The significant difference between the two is that the kitchen sink requires extra space for accommodating kitchenware like large pots and pans.
Final Thoughts
The sink’s size, shape, and depth are usually considered based on the personal preference of the user as well as the bathroom’s floor space. In general, a bathroom basin will offer around 5 to 8-inch-deep sinks. This measurement is due to the computation that also considers the height of an average person.
Keep in mind that bathroom sinks are not strictly standardized when it comes to their specification. Bathroom basin measurements are pretty broad, in general. However, you can expect most washbasins to fit within the standard countertop design.
As for how deep your bathroom sink should be, consider comfort and overflow/splash-proof when it comes to narrowing down your options.Â
