Choosing the Perfect Water Closet: A Plumbing Designer's Guide

Choosing the Perfect Water Closet: A Plumbing Designer's Guide

Ruhe |

Selecting the right water closet for a project, whether commercial or residential, involves a lot more than just picking a toilet/commode. As a plumbing designer, understanding the nuances of various types of water closets, flushing cisterns and their components can significantly impact the functionality, hygiene, and aesthetics of a bathroom. 

This blog will cover everything from the basics of toilet bowls to more complex elements like flushing accessories and water system design.

Understanding Different Types of Toilet Bowls

Toilet bowls come in several shapes and sizes, but the most common are round and elongated bowls. Round bowls are space-savers, making them ideal for smaller bathrooms typically found in residential settings. Elongated bowls, on the other hand, offer more comfort and are preferred in commercial environments where user comfort is a priority. Both types can be fitted with either an open-front toilet seat cover, often required in commercial settings for hygiene reasons, or a closed-front seat cover, more common in residential settings.

Choosing Between Wall-Mounted and Floor-Mounted Water Closets

The choice between wall-mounted and floor-mounted water closets can drastically influence the plumbing design and the final look of the bathroom. Wall-mounted western commodes are great for modern bathrooms, making cleaning easier and maximising space. They require a sturdy wall installation and an in-wall tank system, which can complicate the installation process but result in a sleek look. Floor-mounted closets are the traditional choice, easier to install and maintain, making them suitable for both residential and commercial buildings.

Flushing Accessories: More Than Just a Choice

Flushing Accessories

Flushing technology plays a crucial role in the functionality of water closets. The primary options include flush tanks and flushometer tanks. Flush tanks, commonly seen in residential bathrooms, rely on gravity to flush the waste. Gravity flush systems are straightforward and cost-effective but can vary in water efficiency.


On the other hand, flushometer tanks, or valve systems, are often used in commercial settings where the plumbing design can handle the higher pressure that these systems require. They are more durable and efficient, ideal for heavy usage environments. Sensor-operated flush valves represent an advancement in this technology, offering hands-free operation which increases hygiene—an essential factor in today’s design considerations.

Commercial vs. Residential Fixtures

When it comes to commercial versus residential water closets, the differences extend beyond mere aesthetics. Commercial bathrooms cater to high usage and are subject to stringent codes for accessibility and hygiene, requiring more durable fixtures and often more complex installations. Residential fixtures prioritise comfort and style, integrating seamlessly into the design of the home.

Hygiene and Aesthetic Considerations

Hygiene is paramount in any bathroom design. Easy-to-clean surfaces, minimal contact points, and automated features like sensor-operated flush valves help maintain cleanliness and reduce the spread of germs. Aesthetically, the water closet should align with the overall style of the bathroom. This consideration is where wall-mounted units often have an advantage, as they can blend into the background more smoothly than floor-mounted units.

Water System Design and Installation Types

Plumbing designers must also be knowledgeable about the overall water system design. This system includes the supply of water to the bathroom and the efficient removal of waste. The choice of water closet can affect these systems significantly. For example, certain high-efficiency flush systems can help maintain environmental standards and reduce water usage, crucial in areas with water use restrictions.

Installation types vary from one water closet to another. Wall-mounted toilets require a different framing and waste routing compared to floor-mounted models. Knowing the details of each installation type helps in planning the bathroom layout and ensuring compliance with local plumbing codes.

Selecting the appropriate water closet involves a comprehensive understanding of numerous factors, from the type of toilet bowls and their seating to the more technical aspects of flushing mechanisms and plumbing designs. Whether designing for a commercial or a residential space, plumbing designers must balance functionality, hygiene, aesthetics, and compliance with standards to achieve a successful installation.

For each project, it’s essential to consider the specific needs and constraints of the space and usage. With the right knowledge and approach, plumbing designers can ensure that they choose the most appropriate fixtures that will perform well over time, meet users' needs, and integrate seamlessly into the overall design of the space.
