The average life expectancy of a toilet seat is five years or longer.

For one, the materials used in manufacturing a toilet seat have a big impact on how long it will last. There are several different materials used in making toilet seats but we can divide them into three broad categories:

Plastic Toilet Seats

Today, plastic is perhaps the most widely used material for toilet seats. You may be unaware of this but toilet seats are generally made from a variety of plastics which are more durable than wood or any of the other alternatives. However, within the plastic group, there are a few unique differences. Polypropylene, for example, is mostly used in the production of lightweight but poorly constructed toilet seats that you typically see in cheap apartments. While polypropylene toilet seats are long-lasting, they are known to turn yellowish over time. So, knowing this and how to replace toilet seats may help you in the long run. 

Some plastic toilet seats may also be made of Duroplast

Some plastic toilet seats may also be made of Duroplast, which is a very durable material but not environment-friendly because it takes ages before it can disintegrate. On the good side, there are also the resin toilet seats which are more durable than the common plastic seats, have a better external appearance and are made of natural materials.

Wood Toilet Seats

Since they are more vulnerable to breaking, can rot, and can easily fade their finish, wooden toilet seats usually do not last long as plastic toilet seats. The majority of today’s wooden toilet seats are made of compressed wood materials and are usually painted white. So it can be difficult to differentiate them from plastic toilet seats. 

wooden toilet seats usually do not last long as plastic toilet seats.

The standard solid-wood toilet seats are also more likely to break than compressed wood toilet seats but what gives them the advantages is that they don’t get as cold as the plastic especially during the cold season. Also compared to the dull white of standard plastic toilet seats, toilet seats with a real wood finish do have a much better look.

Cushioned Toilet Seats

Cushioned toilet seats aren’t as durable as wood or plastic seats. This is because its outer plastic is prone to cracking. If this occurs on a padded toilet seat, it should be removed. Otherwise, it would begin to cause more issues for you. Furthermore, since the holes in a padded toilet seat are difficult to scrub, they can also become a breeding ground for bacteria.

Not all toilets are created equal.

Not all toilets are created equal. Their bowls come in a variety of styles, including elongated, round-front, with hidden trap ways, and some are skirted. Each bowl requires a unique, precisely measured bench. Other considerations, such as color and finish, should also be weighed until the correct size and form have been chosen. 

Installing a new toilet seat is less expensive than replacing an older one

Installing a new toilet seat is less expensive than replacing an older one because the screw holes will need to be repaired before the new seat can be assembled, especially if the bolts holding the seat in place have become rusted or stripped. In this case, the work will necessitate more supplies and will boost the project’s expense. 

On the other hand, seats for normal toilets are less expensive than those for elongated or round bowls or have unusual dimensions.

How to Measure Toilet Seat Size?

No matter what kind of toilet bowl you have, you’ll need to know how to measure toilet seat size. So you have to measure the width and length of the toilet seat, its bolt spread, and the length of the wall gap. To measure, you’ll need a tape measure, a pad, and a pen. So while toilet seats are now available in standard sizes, it is always a good idea to measure the current seat before purchasing a replacement. 

How to Replace Toilet Seat Width

  • Taking the Width of Toilet Seat

The width of the curvy toilets can be insignificant when choosing a toilet seat because it is the dimensions and weight that should be determined. However, knowing the width of a toilet with an irregular form, such as a cube, rectangle, or d-shape is very important when replacing a toilet seat. To measure, use a tape measure and get both sides of the bowl starting at the widest point.


  • Measuring the Length of Toilet Seat

When detaching a toilet seat, you will see two holes where the seat screws are in. After detaching the seat, clean the area to measure. Position the tape measure from the center of the two holes and extend it over the toilet rim’s longest section. Then extend the measurement up to the toilet’s edge.

The length of the toilet seat would be around 16 to 18 inches long, provided that the toilet bowl is curvy. Buy a round toilet seat if the toilet bowl is 16 to 17 inches in length but you’ll need an elongated elliptical toilet seat if it’s 18 to 19 inches in length. Remember that the measurement of the toilet seat is unaffected by the toilet height.

toilet bolt

  • Considering the Toilet Bolt Spread

It’s essential to double-check the distance between the toilet seat’s two holes in the back. The bolts, mounting clips, or screws hold the toilet lid and toilet seat intact.  Bolt spread is the term for the distance between the bolts. Stretch the tape measure from the center of one hole to the center of the other.

The 5.5 inch bolt spread requires American toilet seats, while the 6.5 inch bolt spread requires a European-made toilet. However, It’s also quite possible that you can have a variant with a unique style. Since some specialty versions (such as D-shaped and square toilets) have bolt spreads of up to 10 inches, the form of the toilet seat should make a big difference. 

Wall Gap

  • Measuring the Length of the Wall Gap

In measuring tankless toilets, D-shaped toilets, and other specialized toilets, stretch your tape measure up to the wall and then measure the center of the two bolt holes. If the toilet doesn’t touch the wall, take the measurements up to the toilet’s back rim. 

This calculation is important because it influences how the toilet seat is installed. You wouldn’t want to have to cut a toilet seat down because it doesn’t fit as the portable toilet was installed in a tight space. But to know how to measure toilet seat size firsthand, you can experiment with various measurement positions.
