How Much Does A Toilet Weigh? [Including With Water]

When designing your bathroom and planning for the build, it is important to consider the weight of the many bathroom appliances and fixtures. This, of course, includes the toilet. So you are wondering, how much does a toilet plus the toilet water weigh? We have done our research and thoroughly answer that question in this post.

With water, toilets usually weigh between 60 and 130 pounds depending on several factors. These factors include the following.

  • Toilet Type
  • Toilet Material
  • Rough-In Depth
  • Toilet Height
  • Water Requirements

The numbers cited above are rough; expect a wide variability in toilet weights based on the above factors. Keep reading the rest of this post for details of toilet weight variability. We also include the answers to a few related questions.

Weight of Toilet Types

This section will review the major features of the four main toilet types, including their corresponding weights. The toilet types include the one-piece toilet, the two-piece toilet, the wall-hung toilet, and the smart toilet. There is still wide variability of toilet weights within each of the categories investigated here, and you should check the manufacture's reported weight when purchasing a toilet.

Two-Piece Toilet

Two-piece toilets are thus named because the bowl and the tank are produced and shipped separately. This makes moving and installing the toilets simpler and lighter. These types of toilets are generally also cheaper but do have a more blocky look.

The bowl of a two-piece toilet usually weighs about 50 to 60 pounds. However, models are available with bowls as light or lighter than 35 pounds. The tank of a two-piece toilet usually weighs between 25 to 40 pounds. This produces an average range of 75 to 100 pounds.

One-Piece Toilet

The bowl and the tank of one-piece toilets are produced together and fused together. This has the effect of a more unified and sleeker look. However, since the bowl and the tank must then be moved together, one-piece toilets are heavier and more awkward to move. Generally speaking, one-piece toilets weigh between 80 and 120 pounds.

Wall-Hung Toilet

Wall-hung toilets attach to the wall instead of the floor. This contrasts with both one-piece and two-piece toilets which sit on the floor. Since the wall, not the floor, supports a wall-hung toilet, these toilets are usually a bit lighter. On average, wall-hung toilets weigh between 40 to 80 pounds.

Wall-hung toilets are an attractive option in terms of easy floor cleaning and modern bathroom design. However, keep in mind that the wall for a wall-hung toilet will need special construction, such as heavier studs like 2x8's instead of 2x4's.

Smart Toilets

All the extra bells and whistles add weight to a smart toilet. Even though they do not always have tanks, they still usually weigh 100 to 120 pounds. This weight does sometimes come with nice functions like heated seats, a bidet, and more.

Toilet Material

Ceramic or porcelain and stainless steel are the two main materials used for toilets. Sometimes the seat is of different material like plastic or wood, but the bowl and tank are almost always one of these two constructions. In this section, we will review each material type and its relative weights.

Ceramic Toilets

Most at-home toilets are made of ceramic, also known as porcelain. This material is durable enough for decades of use, strong enough to act as a frequently used chair, and is easy to clean. These features combine to make ceramic an excellent toilet material. The downside is that ceramic is heavy.

The weights quoted above are all for standard ceramic toilets. That is to say, ceramic toilets weigh between 40 and 120 pounds.

Stainless Steel Toilets

Another toilet material is stainless steel. Stainless steel toilets are much more expensive than their ceramic counterparts and impart a very industrial vibe. For these reasons, it is uncommon but not unheard of to have a stainless steel toilet in a residential home. Rather stainless steel toilets are much more common for high traffic public areas.

Stainless steel toilets are significantly lighter than porcelain toilets and usually never weigh more than 60 pounds. However, a wide variety of stainless designs impact the actual final weight of these toilets.

Rough-In Depth

The rough-in depth of a toilet indicates where to put the waste hole in the floor of a home. For example, a 12-inch rough-in means that the contractor cuts a hole 12-inch from the finished wall. It is also common to install 10-inch and 16-inch rough-in toilets.

The additional inches of a 16-inch rough-in can include up to 20 pounds of additional weight. This is well demonstrated by the two toilets linked below. Both of these are standard two-piece toilets.

The rough-in depth of a toilet is one of the major considerations when deciding how much room a toilet needs. However, this is not the full story. Visit this article to learn all you need to know about how much space a toilet needs, "How Much Space Do You Need For A Toilet?"

Impact of Seat Height

Most toilets have a seat height of around 16 inches. Lower seat heights mean less material, so a lighter toilet. A tall toilet, which some prefer for comfort reasons, can increase the weight significantly. Taller toilets usually weigh up to 30 pounds more. This is well demonstrated by the 20-inch tall toilet pictured below, which weighs a whopping 120 pounds.

Water Requirements

Usually, toilet weight as listed on specifications sheets and sales websites only include the unfilled toilet. Toilets hold water both in the bowl and in the tank. Understanding the size of both of these features is required to determine the final weight of a toilet. To get the final weight, add the water weight to the specified unit weight.

Fortunately, this math is not super hard to do. A single gallon of water weighs 8.33 pounds. Simply multiply the water required by your toilet by the above water weight to see how much weight the water will add to your toilet when filled.

The amount of water a toilet holds changes by the age of the toilet and type of toilet. Older toilets use up to seven gallons of water per flush, so they must hold all that water. Newer toilets use much less, sometimes as low as 1.28 gallons of water. In terms of weight, this is a 50-pound difference.

Also, many toilets do not have tanks but instead use pressure from the house. The weight of these types of tankless toilets changes much less when filled because of the lowered water requirements. Both wall-mount and smart toilets often are tankless.

Finally, the bowl of a toilet usually holds between one and two gallons of water. So when you add the tank and the bowl of a modern toilet together, the water usually weighs 10 to 20 pounds. An older toilet, on the other hand, has up to 60 pounds of water.

How much weight can a toilet hold?

How much a toilet holds depends on the toilet type and specifications. Most toilets are designed to easily hold 500 pounds, even wall-mounted toilets. Many floor-mounted toilets are designed specifically to hold up to 1,000 pounds. When shopping, be sure to take a look at weight limits to make sure you get a toilet that fits your needs.

Can one person lift a toilet?

Whether or not a person can lift a toilet depends on the person and the toilet. A two-piece toilet, if moved in two pieces, is usually within the capabilities of most people. However, a heavy one-piece toilet weighs more than most people can easily handle. 

When lifting toilets, be sure to lift within your capabilities or risk injury. It is even better to recruit a friend to help or even hire a professional to do the lifting for you. If you do decide to lift your toilet alone, be sure to use safe lifting practices and do your research on tricks first.

What is the best material for a toilet?

The best material for a toilet depends on your home decor and budget. Given the tried and true nature of ceramics, it is often considered the best toilet material. However, if you have a modern-looking home, perhaps stainless steel is right for you.

In Closing

This article has covered a wide range of factors influencing toilet weight. As shown, toilets can weigh anywhere from 60 to 130 pounds with water. The exact weight can change dramatically, so be sure to look at toilet specifications before purchase. Good luck!
