Therefore toilets sold in the US must adhere to the weight limit requirement.

Different models of wall hung toilets have different weight limits. Here are three examples of the best wall mounted toilet models and the average weight load they can support:

  • Toto Aquia wall hung dual flush toilet – 880 pounds. We can use the Toto Aquia with the Toto in-wall tank system (source: reply to our inquiry from Toto USA ambassador on Home Depot)
  • Kohler Veil wall-hung Toilet – 500+ pound (source: Kohler websites)
  • American Standard Glenwall wall toilet – 500+ pound (source: Home Depot questions and answers replies)

Based on a statistic, an average American woman weighs 166 pounds while an average American man weighs 196 pounds. So, a wall-mounted toilet with a minimum weight capacity of 500 pounds is more than enough to withstand our weight for household use. 

The US regulation for the average weight limit of wall-hung Toilet 

It is a requirement that all wall hung toilets sold in the US must support the minimum weight-bearing capacity of up to 500 pounds. The National Consensus Standards set this requirement for Vitreous China Plumbing Fixtures, ASME A112.19.2-2005/CSA B4 5.1-05. However, according to the results from above, the average minimum weight limit of different wall-mounted toilet bowls is even higher than the supposed 500 pounds requirement. Although the strength of the Toilet depends on the model and the brand. 

Moreso, when we consider the floor-mounted toilets, no standards are specifying the average minimum weight limit that it can withstand. Nonetheless, most floor-mounted Toilets have an average standard toilet weight limit of about 1000 pounds (453kg). On average, wall-mounted toilets can only endure about half of the weight capacity of regular Toilets.

So, when you reduce the weight of the bowl, the carrier would still be able to support around 750-800 pounds in excess. 

What is the average strength of a wall?

Generally, it is the wall that limits the average weight limit of a wall-mounted toilet and not the frame or the Toilet itself. Even though by specifications, a carrier should withstand up to 880 pounds, it will not if the wall does not match up to the maximum weight limit of the Toilet. When the frame is not secured correctly, it will also lead to problems later.
