It is crucial to measure the size correctly while purchasing or replacing a bathroom sink. Be it for fitting an existing countertop, available space in case of installation, or to create a custom size, accurate measurement can prevent rework and installation problems.
As a professional manufacturer focusing on the design, manufacturing, wholesale and customization of ceramic bathroom sinks, HanYu will explain to you in detail the main procedures and precautions for measuring bathroom sinks accurately.
Prepare Tools
Before you start, you need to prepare the following common tools:
- Tape measure
- Marker or pencil
- Recording paper
If it is a recessed installation, it is also recommended to prepare a level ruler
Determine the Type of Sink
Different types of sinks have slightly different measurement methods. Common types are as follows:
- Above-counter bathroom sink: placed on the countertop with exposed edges
- Under-counter bathroom sink: installed under the countertop with hidden edges
- One-piece bathroom sink (countertop integrated): the wash basin and the countertop are formed in one piece
- Wall-mounted bathroom sink: wall-mounted design, no countertop support required
- Floor-standing bathroom sink: comes with a base, commonly seen in free-standing bathroom designs
Please confirm your wash basin type before measuring.
Specific Measurement Steps
Measure the Length of the Basin
This is the maximum horizontal distance between the left and right ends of the wash basin, which is usually one of the most important dimensions.
Applicable to all types of bathroom sink
Measure the Width of the Basin
Refers to the entire depth of the bathroom sink from the front to the back, and particularly important in wall-mounted or recessed installations.
Note: The width should be wide enough to accommodate the faucet mounting and drainage space
Measure the Basin Height
- For above-the-counter basins: measure the height from the bottom to the highest point of the basin
- For under-the-counter basins: measure the depth of the embedded part (the thickness of the countertop must be considered during installation)
- For wall-mounted basins or floor-standing basins: measure the overall height
Measure the Distance Between Faucet Holes
If the bathroom sink comes with multiple faucet installation holes (such as hot and cold double holes), please measure the center distance between the holes in centimeters or inches.
Measure the Position of the Drain Hole
Measure the position of the drain hole from the back wall and the distance between the center point and both sides of the bathroom sink body, which is crucial for the reserved position of the drain pipe.
Additional Suggestions
- If you are replacing an old basin, please remove the wash basin fisrst and then measure to obtain the most accurate data
- If you are customizing the wash basin, it is recommended to measure 2-3 times to confirm the consistency of the data
- If you are unsure of the measurement, you can take a photo and note the size and send it to the HanYu team. We will provide you with professional advice and matching model recommendations
