That is for the toilet mounted on the floor that usually comes with a base to enable users gain support from the floor and also the toilet. In this type of toilet system, the weight limit does not depend on the toilet seat you have mounted on the wall but rather on the quality of the porcelain material used in creating it which is highly rigid and super strong. Because of this material quality, most normal toilets can support more than 1000 pounds. This is good news because a toilet made with poor materials can be dangerous to the user.

For the wall-mounted toilet weight limit, we’re looking at 500 pounds. This is half the limit of the standard toilet. The reason while the limit for this is less is that the toilet system does not have any support from underneath. The support it receives is from the connection to the wall. Because it doesn’t have any underneath support, it can’t carry as much as 1000 pounds. This type of toilet system needs to get support from the screws of the wall to ensure it bears the added weight limit.

Therefore a wall mounted toilet weight limit is adequate for personal use. Even at 1000 pounds, the normal toilet weight limit is perfectly adequate for users to sit on.
