If you’re a homeowner or renter, knowing how to install a toilet can come in handy when it’s time to replace your old one or if you’re moving into a new home with a toilet that needs to be installed. This article is a step-by-step guide to installing a toilet, providing all the necessary information and tips you need to complete the job correctly the first time around. From choosing the right toilet to avoiding common mistakes, we’ll cover everything you need to know to successfully install a toilet on your own.

Step-by-Step Guide to Installing a Toilet

Installing a toilet can be an intimidating job, but it doesn’t have to be. Follow these simple steps for a hassle-free installation.

Step 1: Removing the Old Toilet

The first step is to remove the old toilet. Start by turning off the water supply and then remove any remaining water from the tank and bowl. Once you have removed as much water as possible, disconnect the bolts and nuts that hold the toilet to the floor, then lift the toilet off the flange and move it out of the way. Be sure to plug the exposed sewer line with a rag to prevent any unwanted gases from entering your home.

Step 2: Prepping the Area

Before installing the new toilet, you need to prep the area. Clean off the old wax ring from the flange, and remove any debris or old caulk. Then measure the distance between the wall and the toilet flange to ensure that the new toilet will fit properly. If you’re replacing a toilet, be sure to take note of the existing water supply and drain location so that you can match them with the new toilet.

Step 3: Installing the New Toilet

The next step is to install the new toilet. Place a new wax ring onto the flange, and then position the new toilet over the ring, being careful to keep it level. Secure the toilet to the flange with bolts, nuts, and washers and tighten the bolts evenly to ensure a flat and watertight seal. Then attach the water supply line and adjust the water line to the recommended level. Lastly, test flush the toilet and check for any leaks.

Tips and Tricks for a Successful Installation

Here are a few tips and tricks to make the installation process easier and more successful.

  • Use a new wax ring: It’s essential to use a new wax ring when installing a new toilet to ensure a proper seal and prevent leaks.
  • Be careful not to overtighten the bolts: Over-tightening the bolts can cause the toilet to crack. Tighten just enough to create a watertight seal, but not too much.
  • Check the waterline level: The waterline level should be around 1 inch below the rim of the overflow tube in the tank. Adjust it as necessary to ensure proper flushing.

Comprehensive Guide to Choosing the Right Toilet

Choosing the right toilet is an essential part of the installation process. Here are some factors to consider when selecting a toilet.

Factors to Consider

  • Size and Shape: Toilets come in different sizes and shapes, including round, elongated, and compact shapes, so be sure to choose one that fits your bathroom space and meets your needs.
  • Style: You can select a traditional or contemporary style that matches your bathroom d├ęcor and personal preferences.
  • Water Efficiency: Choosing a water-efficient toilet can save water and money on your monthly bills.

Detailed Information on Each Type of Toilet Available

There are different types of toilets available to choose from, including:

  • One-piece vs. Two-piece: One-piece toilets are easier to clean and have a sleeker look. Two-piece toilets are more affordable and easier to maneuver during installation.
  • Round vs. Elongated Bowl: Round bowls are more affordable, take up less space, and are best for smaller bathrooms. Elongated bowls provide more comfort and are easier to clean.

Considerations When Selecting a Toilet Based on Your Existing Plumbing

It’s important to consider your existing bathroom plumbing when selecting a toilet. If the existing toilet flange is not level, you may need to purchase a specific type of toilet to ensure proper installation and prevent leaks.

Common Mistakes and How to Avoid Them

While installing a toilet may seem like a straightforward process, it’s common to make mistakes. Here are some frequent mistakes people make and how you can avoid them.

  • Improper Wax Ring Placement: Placing the wax ring in the wrong position can cause leaks. Ensure that the wax ring is in the right place before installing the new toilet.
  • Over-tightening the Bolts: Over-tightening the bolts can lead to toilet cracking or warping. Tighten the bolts only until the toilet is secure and doesn’t wobble.
  • Not Leveling the Toilet: If the toilet is not level, it can cause leaks and potential damage to your bathroom floor. Ensure that the toilet is level and flushes correctly before using it.

Tools Required for Installing a Toilet and How to Use Them

Here are some of the necessary tools and how to use them.

  • Wrench: A wrench is necessary for removing and securing bolts.
  • Screwdriver: Used for removing screws and adjusting components of the toilet.
  • Plunger: Used to ensure proper water flow through the toilet after installation.
  • Level: A level is essential to ensure that the toilet is level and does not cause potential floor damage.
  • Closet Auger: A closet auger helps in clearing clogs down the drainpipe of the toilet.
  • Putty Knife: A putty knife helps remove old wax rings, caulk, and other debris from the installation area.

The Cost of Hiring a Professional vs. Doing it Yourself

You may consider hiring a professional to install your toilet, but it can be costly. According to Home Advisor, the average cost of installing a toilet can range from $125-$260.

However, if you choose to install the toilet yourself, you’ll only pay for the cost of the new toilet, wax ring, bolts, nuts, washers, and caulk.

The downside of installing the toilet yourself is that if you make a mistake, it may cost you more money in the end to repair it. Hiring a professional may give you peace of mind, knowing that the job will be correctly done.


Now that you know how to install a toilet, choosing the right toilet, common mistakes to avoid, and where to find helpful resources like video tutorials, you’re ready to tackle the job confidently. Whether you decide to hire a professional or install the toilet yourself, you’ll have the knowledge and information needed to make an informed decision, and you’ll likely save some money in the process.

Remember always to take the necessary safety precautions when installing a toilet and be especially careful when moving heavy fixtures, such as the toilet itself.
