While there are no hard and fast rules for bathroom wash basin sizes, most sinks do fall into a standard range of dimensions. Keep these in mind to find the perfect wash basin for your bathroom design!

Figuring out the right washbasin measurements for your bathroom can be a little complicated. Much of the time, for bathroom wash basin dimensions you need to first consider the shape and type of sink before you understand the wash basin dimensions that manufacturers provide.

Many product descriptions, particularly for undermount, vessel, and drop-in sinks, take available washing space as the most important part of wash basin size, only giving you the inside dimension. While, with wall-hung and pedestal sinks, the outside dimensions are usually indicated, giving you a better idea of basin size for the bathroom space available.

With this handy guide to wash basin size in inches, you’ll gain some insight into the standard wash basin dimensions. So, while doing up your bathroom, wash basin size will no longer seem so confusing!

How to Measure Wash Basin Size?

 

  • Length:  The length of the washbasin measured parallel to the back wall.
  • Width: Take the distance that runs perpendicular to the back wall for these wash basin measurements.
  • Height: The standard wash basin height is measured on the outside of the sink from top to bottom.
  • Depth: The distance from the overflow hole to the drain opening is how the wash basin standard depth is taken. If there’s no overflow, depth is measured from the top of the rim to the drain opening.

Common Wash Basin Sink Dimensions

 

1. Rectangular & Oval Wash Basin Dimensions

  •   Small: 15” - 20” length, 9” - 12” width & 5¾” - 7” depth are common wash basin small size measurements.
  •   Medium: 20” - 30” length, 19” - 24” width & about 7” depth is the standard dimension of wash basin in medium size.
  •   Large: 30” - 50” length, 19” - 24” width & about 5” depth is the standard dimension of wash basin in large size. This large wash basin size works better as wall mounts than as drop-ins.

 

With the wash basin dimensions of an oval sink, take the length as the longer axis and the width as the shorter one. If a product description mentions diameter, that will refer to the length and width.

4. Vessel Wash Basin Dimensions

While still keeping your wash basin small, these over-counter sinks can be wider and deeper than others, depending on the height of your vanity. The wash basin standard size range for round vessel sinks is 14” - 20” in diameter & 4”- 7” deep. Rectangular and square ones may have a shallower wash basin with a minimum size and run 15” - 25” long & 16” - 20” “wide.

 

5. Pedestal Wash Basin Dimensions

Remember that wash basin full pedestal dimensions are outside dimensions. While the classic length is between 22” & 28”, these days length usually varies from 15½” - 30”. The width can also vary, but is usually between 17” and 20”. As for the standard wash basin height of wash basin full pedestal, it is usually 29” - 34” tall.

 

6. Countertop Wash Basin Dimensions

Countertop wash basins add a chic touch to any bathroom. Typically, these basins range from 16 to 24 inches in width and 5 to 8 inches in height. However, the exact size can vary depending on the specific design and style. When selecting your basin, ensure it fits comfortably on your countertop design.

7. Under-Mount Sinks Dimensions

Under-mount sinks, installed beneath the counter, provide a sleek look. The standard measurements for these sinks are usually around 20 to 24 inches in width and 6 to 8 inches in depth. However, dimensions can differ based on the model and manufacturer. So, always verify the countertop cut-out dimensions before installation.

 

8. Semi-Pedestal Sinks

Semi-pedestal sinks, which are wall-mounted with a partial pedestal hiding the plumbing, typically measure around 18 to 24 inches in width and 5 to 8 inches in height. The depth of the sink can vary, but it's usually between 14 to 20 inches. These sinks are excellent for smaller bathrooms where saving floor space is essential.

 

9. Integrated Wash Basins Dimensions

Integrated wash basins, where the countertop and basin are one piece, offer a modern look. These basins can range from 20 to 47 inches in width, depending on the countertop length. The average height is about 6 to 8 inches. The precise dimensions will depend on the specific design and space available in your bathroom.

 

10. Under Counter Basin Dimensions

Under-counter basins, similar to under-mount sinks, are installed below the countertop for a clean, streamlined appearance. These basins usually measure between 20 to 24 inches in width and around 8 inches in depth. The exact size can vary depending on the style and manufacturer. Ensure your countertop has enough space for the basin before installation.

Bathroom Wash Basin Dimensions to Remember:

  • The perfect size for a bathroom wash basin should account for the bathroom layout and dimensions as well as your use of the sink.
 
  • For top-mount or under-mount sinks, keep about 2” of space from the front of the countertop to the front of the sink, and about the same between the back of the sink and the backsplash. Your faucet design may impact washbasin measurements.
 
  • The framework of your vanity is more likely to constrain your bathroom basin size than the space you need along the length of the countertop.
 
  • If you want a bigger wash basin on a small countertop, try a vessel sink and wall-mount faucet so the sink rim can extend across the width of the countertop.
 
  • To choose the ideal pedestal or wall-mount basin size for smaller bathroom layouts, try to keep at least 21” from the front of the sink to the facing wall and 30” from the centerline of the sink to the centerline of any adjacent fixture.
