Lavatory vs. Toilet

What's the Difference?

A lavatory and a toilet are both fixtures commonly found in bathrooms, but they serve different purposes. A lavatory, also known as a sink or washbasin, is used for washing hands, face, and brushing teeth. It typically consists of a basin with running water and a faucet. On the other hand, a toilet is used for bodily waste elimination. It includes a bowl, a seat, and a flushing mechanism. While a lavatory focuses on cleanliness and personal hygiene, a toilet is designed for sanitation and waste disposal. Both fixtures are essential components of a functional bathroom, serving different functions to ensure hygiene and convenience.

Further Detail


When it comes to the essential fixtures in a bathroom, the lavatory and toilet are two of the most important components. While they both serve the purpose of personal hygiene and waste disposal, there are distinct differences between the two. In this article, we will explore the attributes of lavatories and toilets, highlighting their unique features and functionalities.

Design and Appearance

One of the primary differences between a lavatory and a toilet lies in their design and appearance. Lavatories, commonly known as sinks or washbasins, are typically designed with a bowl-shaped basin that is mounted on a countertop or vanity. They come in various shapes, sizes, and materials, such as porcelain, ceramic, or stainless steel. On the other hand, toilets are designed as a seat-like fixture with a bowl and a tank. They are usually made of porcelain or ceramic and come in different styles, including one-piece or two-piece designs.

While lavatories are often more visually appealing and can be a focal point in a bathroom, toilets are generally more functional and utilitarian in their design. The focus of a lavatory is on providing a convenient space for handwashing and other personal hygiene tasks, while toilets prioritize efficient waste disposal.


When it comes to functionality, both lavatories and toilets serve distinct purposes. Lavatories are primarily used for handwashing, face washing, and other personal hygiene tasks. They are equipped with faucets and often have additional features like soap dispensers, mirrors, and storage cabinets. Lavatories are essential for maintaining cleanliness and promoting good hygiene habits.

On the other hand, toilets are designed for waste disposal. They are equipped with a flushing mechanism that allows for the efficient removal of bodily waste. Toilets are connected to a plumbing system that carries the waste away from the bathroom and into the sewage system or septic tank. The functionality of a toilet is crucial for maintaining sanitation and ensuring proper waste management.

Installation and Placement

Another aspect to consider when comparing lavatories and toilets is their installation and placement within a bathroom. Lavatories are typically installed on a countertop or vanity, which provides a convenient space for placing toiletries and other bathroom essentials. They require plumbing connections for water supply and drainage.

Toilets, on the other hand, are installed directly on the bathroom floor or mounted on a wall. They require a dedicated plumbing connection for water supply and a separate drainage system. The placement of toilets is usually determined by the existing plumbing infrastructure and the layout of the bathroom.

Maintenance and Cleaning

Both lavatories and toilets require regular maintenance and cleaning to ensure proper functionality and hygiene. Lavatories need to be cleaned regularly to remove dirt, soap scum, and other residues. Depending on the material, specific cleaning agents may be required to avoid damage to the surface. Additionally, faucets and drains should be checked for any leaks or blockages.

Toilets, on the other hand, require more frequent cleaning due to their direct contact with waste. The bowl and seat should be cleaned regularly using toilet cleaners or disinfectants to prevent the buildup of bacteria and odors. The flushing mechanism and tank should also be inspected for any issues, such as leaks or malfunctions.

Accessibility and Adaptability

Accessibility and adaptability are important considerations when it comes to lavatories and toilets. Lavatories should be designed and installed at an appropriate height to ensure accessibility for people of different ages and abilities. They should also provide enough space for wheelchair users to maneuver comfortably.

Toilets, on the other hand, should be designed with ergonomics in mind. The seat height and shape should be comfortable for users, and grab bars or handrails can be installed to assist individuals with mobility challenges. Additionally, there are specialized toilets available, such as raised or bidet toilets, which cater to specific needs.


In conclusion, while lavatories and toilets are both essential fixtures in a bathroom, they have distinct attributes and functionalities. Lavatories focus on handwashing and personal hygiene, with an emphasis on design and appearance. On the other hand, toilets prioritize waste disposal and sanitation, with a focus on functionality and maintenance. Understanding the differences between lavatories and toilets can help in making informed decisions when it comes to bathroom design, installation, and maintenance.
