Average Toilet Weight Limit: How Much Weight Can A Toilet Hold?

Have you ever wondered, how much weight can a toilet hold? In some situations you might even need to know a toilet’s weight limit.

In general the average toilet weight limit is around 1000 pounds (453kg). However, there are no standards or regulations that specify a minimum or maximum toilet weight limit for normal standard toilets. However most toilets can bear a higher weight limit than 1000 pounds, because the Vitreous China (Porcelain) materiel they are made of is super strong and highly rigid.

I’m sure this is comforting news for you, because a defective toilet can be an awful, awful thing. Let’s face it, big or small, we all need to use the toilet and when that happens, the thing better not give way beneath us. Fortunately our modern Vitreous China toilet (what we call porcelain) is super strong and highly rigid.

Wall Hung Toilet Weight Rating

Wall hung toilets have a lower average weight limit than normal standard toilets. The average wall mounted toilet weight limit is around 500 pounds. (But some models like Toto Aquia wall toilet have higher weight limit like 880 pounds if used with Toto wall toilet carrier frame.)

Wall hung toilets also have a 500 pounds minimum load bearing requirement as per the ASME standard (ASME A112.19.2-2005/CSA B4 5.1-05 National Consensus Standards for Vitreous China Plumbing Fixtures.) On the other hand,

Is The Average Toilet Weight Limit Adequate?

In general, the average American man weighs around 196 pounds and the average American woman weighs around 166 pounds. Even severely obese or Bariatric weight range people rarely exceed 400 or 450 pounds. So even the 500 pound wall mounted toilet weight limit is more than adequate for normal household use. Therefore, standard toilet weight limit of 1000 pounds is more than adequate for any eventuality you might face.

But I have to say, even though I have been in the toilet marketing field for sometime now and I have never seen any toilet listing it’s weight capacity. So, over the last few days, I did a very detailed online research about, “how much weight can a toilet support?” I wanted to find some solid answers about the average toilet weight capacity of the best toilet brands and models.

I had to do a lot of research to find out the details I’m sharing here about toilet weight limits. It was a very difficult task, because toilet manufacturers don’t give out these details about how much weight their toilets can hold.

KOHLER Toilet Weight Limit

A remote page on the Kohler website provided the only reference to toilet weight bearing ability I could find about any popular toilet brands. According this lone document from Kohler, their normal floor toilets are capable of withstanding a vertical force of up to 1000 pounds. That’s more than the weight of the heaviest man in recorded history. So, if you are worried you or your visitors might accidentally break a toilet bowl while using it, you can rest easy by getting one of the top rated Kohler toilets.

What About Toto or American Standard Toilets Weight Limits?

Surprisingly, I couldn’t find any reference or mention of toilet weight limit from these best toilet brands and models. There was not a single mention or reference to weight load from Toto, American Standard or any other famous toilet brands except for some of their wall hung toilet models.

However, I found many Toto and American Standard toilet reviews and comments on different Internet Forums and on Online stores like Amazon from people weighing 250, 300 pounds and more. They were all glad and recommending these top brands for bearing their weight well.

Can You Break A Toilet By Sitting On It?

One thing I observed during my research was, I didn’t find any mention of a toilet ever breaking under the weight of anyone. When I was researching I expected to find many horror stories about toilets cracking and injuring people. However, there were many mentions of toilets wobbling or toilet floor bolts becoming loose or toilet seats breaking. Gladly not a single report about someone breaking a porcelain toilet with their weight.

I think durability of modern toilets is largely due to what toilets are made of, some kind of treated Porcelain or Vitreous China clay. This toilet making material seem to do a great job in holding us safely while helping us relieve.

Why Do Toilet Brands Not Mention Weight Limits?

It is very strange, there is so much lack of information on toilet weight limits. With a growing number of obesity level in the country you might think otherwise.

These days, toilet marketing materials and specification sheets mention almost every little feature and advantage of their toilet models. I think when no one else mentions their toilet models weight limit, mentioning your toilets weight bearing capacity would be a great marketing advantage.

With a increasingly obese and weight conscious population, wouldn’t it be massive marketing advantage for a toilet manufacturer if they mention, how much weight can the regular toilet bowl take, with a ad like, “XX model, supports more than 1000 pounds” etc.?

How much weight can a Toilet Seat hold?

Another related question to toilet weight limit is about the weight limit of toilets seats. Do toilet seats have a weight limit? Yes, they do have a weight limit though its often not mentioned just like the weight limit for toilets.

The average toilet seat weight limit is about 300 pounds. That’s why most normal toilet seats crack or break very soon. Most normal toilet seats aren’t built to withstand even a bit of wriggling even by normal average weight users. So no wonder when heavy users use a normal toilet seat, you usually find them crack, creek and complain. That’s why special heavy duty seats like this Bariatric Toilet Seat, 800 lb. Capacity sold on Amazon are very popular.

When I moved to my new house last year, I found a good normal toilet seat on the hall toilet with a small crack in the middle. Every time I sat on it and got up, it used to pinch my back! I found out the previous occupiers grandson weighed around 300 pounds and used this toilet.

So if someone heavy is going to use your toilet, I highly recommend getting heavy duty toilet seat like the above than a normal toilet seat. They are costly but in the long run you will be saving time and money and won’t become tired of replacing your toilet seat.
