Since they have been in use for more than a century, wall-hung toilets have undergone several modifications and enhancements. Thomas William Twyford, an Englishman, created the first wall-hung toilet in 1885. In Twyford’s plan, a cast-iron bowl was suspended from the wall by brackets. The bowl was joined to an S-shaped trap with a soil pipe as its outflow.

Wall-hung toilets gained popularity over time, and a variety of styles were created. The American Standard firm unveiled a wall-hung toilet with a ceramic bowl and an enclosed tank in the 1930s. Compared to earlier designs, this one was cleaner and more hygienic.
The popularity of wall-hung toilets increased in the 1950s, and numerous new designs were produced. The tankless toilet, which had no tank and relied on the water pressure in the pipes to flush, was one of the most widely used models. Compared to earlier designs, this one was more space-efficient and utilized less water.

Wall-hung toilets became in popularity and a number of new designs were produced in the 1970s. The dual-flush toilet was one of the most well-liked models because it gave consumers the option of choosing between a full flush and a half flush based on the volume of waste in the bowl. This design helped down water bills and was more water-efficient than earlier designs.

Wall-hung toilets are still widely used today, and numerous new designs are being created. Toilets with built-in bidets, toilets with self-cleaning components, and toilets with touchless flushing systems are some of the most well-liked types. Compared to earlier designs, these new ones are more hygienic, water-efficient, and practical.

In conclusion, wall-hung toilets have advanced significantly since they were first created more than a century ago. Over the years, they have undergone several changes and advancements, and they still experience development now. Wall-hung toilets are more hygienic, water-saving, and practical than ever before, and they will undoubtedly continue to be a popular option for many years to come.
