Sinks

Installing a new sink in the bathroom requires specific measurements to avoid any issues regarding its uses. Therefore, while choosing the type of sink will be vital, you also need to consider the height of the sink. Now, this one is relative to those who will be using the basin daily, but we do have a guideline regarding the ideal sink heights, which we will be discussing below. 

When it comes to the standard sink height, the lowest is 29-inches, while the highest is at 36-inches. The actual measurement will, of course, depend on the people who will be using the washbasin daily. You will also need to factor in the type of sink used, as some have different specifications for the installation process. Also, it is best to check with your local building codes for sink height requirements as well.

Types of Bathroom Sinks and Height Calculation

The type of bathroom sink will often have a prerequisite height when it comes to its installation. Below are the most common sink types that you will find at your local hardware store, as well as their specifications.

Topmount or Drop-in Sinks

This variant is the most common type of washbasin that you will encounter. There is a top lip or rim that is usually about an inch high from the basin’s surface. If applicable, consider the cabinet height, countertop thickness, and the basin’s lips when calculating the appropriate size. 

Undermount Sinks

Undermount sinks install from the bottom, which means that there is no lip visible from the surface. When calculating the sink height, consider the cabinet height and countertop thickness. 

Pedestal Sinks

The pedestal sink is relatively straightforward as the design does not support cabinets or even require countertops. Manufacturers of pedestal sinks offer this type of basin in different sizes as well. However, it would be best to keep in mind whether your existing plumbing system is used with a pedestal washbasin as it utilizes its design. 

Vessel Sinks

This type of basin installs from the top of your countertop. Due to the relatively uncommon installation method, you will need to consider whether the countertop surface can support this type of basin properly. For example, will the vessel sink block any critical features of your countertop? The faucet will also need to be high enough to provide adequate space between it and the basin. However, the higher faucet might obstruct the mirror or electrical outlets. 

As you would have guessed, the vessel basin tends to be the highest sink by default and might cause issues with shorter individuals, children, and those in a wheelchair. 

Wall Sinks

The wall sink is the most versatile in regards to the ability to adjust its height. As the name implies, this type of washbasin attaches to the wall. As such, you have free reign to choose the size depending solely on your preferences. 

You will need to consider the plumbing system and securely attach this type of washbasin to the wall.

Conclusion

The bathroom sink’s height is, for the most part, subjective. The countertop or vanity will most likely be the defining factor in most cases. However, if you wish to achieve the preferred sink height, a wall sink is a good option due to its versatility in this area.
