How to Replace a Toilet: A Step-By-Step Guide


Anecdotal evidence tells us that we're destined to spend about three years of our lives perched on a toilet. Imagine all those special hours with your loyal porcelain companion! 

Yes, it's more than just a fixture; it's a significant part of our daily lives. Ensuring your toilet is comfortable, and a paragon of water efficiency is essential. However, when it's facing stubborn clogs, showcasing cracks from days gone by, or guzzling more water than necessary, it's clearly time to consider a replacement. 

That's where we come in, offering expert advice on how to replace a toilet. Let's dive into this DIY endeavor and aim for a triumphant flush of success.

Here's How to Replace a Toilet 

Your toilet replacement journey begins with a few preparatory steps that ensure a smooth, splash-free process. The adventure starts with an important task: disconnecting the water. Locate your supply valve near the base of your toilet and give it a firm twist to the right. This step is pivotal to avoid an unexpected face wash during the disassembly phase.

After disconnecting the water supply, flush the toilet to drain the tank and bowl of the remaining water, which sets the stage for mess-free removal. Now we're looking at the nuts and bolts, literally. Remove the nuts that secure the toilet to the floor, taking care not to lose these small but crucial pieces. If they're stubborn, a penetrating oil spray can work wonders, ensuring you're not left wrestling with unyielding hardware. 

Lifting the toilet might be tricky, but with a steady grip and a bit of elbow grease, you'll have it off in no time. Strategize your lift to avoid strain or damage to your bathroom tiles. Enlist a helper, if available, to ensure a smooth transition and protect your back during this critical step. This is generally a two-person job. 

Preparing the Space for Your New Toilet 

Before you can welcome your new porcelain pal, there's some prep work to do. First up, let's talk about the toilet flange. This hidden hero of toilet installation needs a good once-over. If it looks worn out or damaged, consider a replacement to avoid future leaks. A clean flange is a happy flange, ensuring a solid foundation for your new toilet.

Moving on to the main player in our toilet installation saga: the wax ring. This sticky sentinel is the watchdog of your bathroom's hygiene, nestled right at the toilet's base, hugging the sewer pipe. The wax ring ensures a watertight seal between your toilet's bottom and the flange, which prevents leaks and odors from permeating your sanctuary. 

But even champions age and the mightiest wax rings may crumble over time. That's where your trusty putty knife comes in, assisting you in clearing the old guard to make way for a new, leak-free era. Replacing the wax ring is a key moment in the installation process, marking the transition from removal to installation with the promise of a fresh, clean start.

It's Time to Install a Toilet

Now that you've prepped the space and waved a fond goodbye to your old toilet, it's time to roll up your sleeves for the main event: installing your shiny new toilet.  

Laying the Foundation with a New Wax Ring

A successful installation lies in positioning the new wax ring on the cleaned toilet flange, ensuring it's centered and ready to create a watertight seal. This step is a biggie; a well-placed wax ring is the first defense against bathroom mishaps, ensuring your efforts result in a secure, leak-free installation. 

Set the Toilet 

Let's welcome the star of the show-the toilet bowl. Hold the toilet so it aligns over the flange and wax ring, lowering it so the mounting bolts slide through the base holes. This moment requires precision and patience. Gently rock the bowl to set the wax ring evenly, ensuring a secure and level fit. Once it feels stable, it's time to secure it in place, marking a major milestone in your installation journey. 

Securing With Washers and Nuts

Here's where we transform your loosely placed toilet into a set, usable fixture. First, tighten the nuts by hand, then use a wrench for the final turns. Be cautious not to over-tighten and crack the ceramic. Think firm but friendly. Then, cap off your handiwork by snapping the bolt caps in place, giving your installation a neat finish. 

Reconnecting the Water Supply

The final step in your toilet installation involves a critical connection: the water supply.  

Reattaching the water lines with care provides a snug fit, which is necessary for the operational success of your new toilet. This moment of reconnection marks the culmination of your hard work as you turn on the water and witness the first flush of your newly installed throne. 

It's a time for celebration! Here is a physical testament to your DIY prowess, a result that elevates you into the realm of "almost professional plumber."  

Finishing Touches and Maintenance

After installing your gleaming new toilet, you're on the final stretch. Now, it's all about adding those finishing touches and understanding how to maintain your new bathroom buddy. These steps ensure your toilet is installed correctly, well-integrated, and ready for daily use. 

The addition of aligning and placing bolt caps over the bolts not only secures your toilet further but also adds a neat finish to the installation. Adjusting the water level in the tank for efficiency guarantees your toilet operates at its best, conserving water and reducing your bills. A thorough clean-up of the area around your new installation removes any traces of the process, leaving your bathroom sparkling and inviting.

Apply caulk around the toilet's base to create a seamless look, merging your new fixture into the bathroom's overall aesthetic. The seat and lid assembly installation are the final step in the physical installation, recasting your toilet from a utilitarian piece to a complete, user-ready fixture. Performing a final flush test for proper operation guarantees everything works as it should and marks the successful end of your installation journey. 

Maintenance Tips

Keeping your new toilet in pristine condition doesn't just happen by chance; it requires a little attention and care. Regular maintenance is key to extending its lifespan and ensuring it works efficiently. Here are a few tips to keep your toilet in top shape: 

  • Regularly clean the bowl and tank to prevent buildup and maintain hygiene

  • Inspecting internal components bi-annually for wear and tear helps catch issues early 

  • Check the seal around the base annually so your toilet remains leak-free

  • Monitor water consumption patterns, which will alert you to any unusual changes 

  • Tightening any loose bolts or connections maintains the stability and functionality of your toilet

By staying proactive with these maintenance steps, you can ensure your toilet remains a reliable and hygienic part of your household, offering comfort and efficiency for years to come. 

When to Call the Professionals

Venturing into the noble quest of replacing your toilet might seem like a straightforward DIY project. But there are moments when even the bravest of homeowners must call in the cavalry. Recognizing when to summon the pros is essential to stop a minor plumbing installation from becoming a full-blown saga.
