Measuring for a toilet replacement is a relatively simple process, but it is important to get the measurements right in order to ensure a proper fit. Here are the steps involved in measuring for a toilet replacement:

1. Measure the distance between the wall and the center of the toilet flange. This measurement will determine the width of the new toilet.
2. Measure the distance from the floor to the center of the toilet flange. This measurement will determine the height of the new toilet.
3. Measure the distance from the back of the toilet to the front of the toilet. This measurement will determine the depth of the new toilet.
4. Measure the distance between the two bolts on the toilet base. This measurement will determine the bolt pattern of the new toilet.

Once you have taken all of these measurements, you can compare them to the dimensions of the toilets you are considering to purchase. Be sure to choose a toilet that is the same size as your old toilet, or you may have to make modifications to your bathroom in order to accommodate the new toilet.

Choosing the Right New Toilet

When choosing a new toilet, there are a few things you need to keep in mind. First, you need to make sure that the new toilet is the same size as the old toilet. This will ensure that it fits properly in your bathroom. Second, you need to choose a toilet that is the right height for your needs.

Some features to consider include a soft-close seat, a built-in bidet, and a self-cleaning toilet.

Here are some of the most popular types of toilets on the market:

  • One-piece toilets are the most common type of toilet. They are made from a single piece of porcelain, which makes them very durable. One-piece toilets are also easy to clean, as there are no seams or crevices where dirt and bacteria can accumulate.
  • Two-piece toilets consist of a separate tank and bowl. Two-piece toilets are typically less expensive than one-piece toilets, but they are also less durable. Two-piece toilets can also be more difficult to clean, as there are more seams and crevices where dirt and bacteria can accumulate.
  • Floor-mounted toilets are the traditional type of toilet. They are installed directly on the floor, and they require a water supply line and a drain line. Floor-mounted toilets are typically the most affordable option.
  • Wall-hung toilets are mounted to the wall, and they do not require a water supply line or a drain line. Wall-hung toilets are typically more expensive than floor-mounted toilets, but they can also be more stylish.
