Welcome Ihsanpedia Friends! Learn How to Change a Toilet

Greetings, Ihsanpedia Friends! Are you tired of your old, outdated toilet? Or maybe it’s time for a bathroom remodel and you want to replace your toilet with a new, modern one. Whatever the reason, changing a toilet may seem like a daunting task, but with the right guidance, it can be a relatively simple DIY project. In this article, we will provide you with a step-by-step guide on how to change a toilet, ensuring a successful and hassle-free experience.


Before we dive into the nitty-gritty details, let’s first understand the basic components of a toilet. A standard toilet consists of a bowl, tank, flush valve, fill valve, flapper, and wax ring. Familiarizing yourself with these parts will make the process smoother.

Now, let’s get started with the step-by-step process of changing a toilet:

Step 1: Gather the Necessary Tools and Materials

Before you begin, it’s essential to have all the tools and materials ready. Here’s a checklist of what you’ll need:

Tools Materials
Adjustable wrench New toilet
Screwdriver New wax ring
Putty knife New bolts and washers
Bucket Plumber’s tape

Step 2: Turn Off the Water Supply

The first step is to turn off the water supply to the toilet. Locate the shut-off valve, usually located on the wall behind the toilet, and turn it clockwise until it stops. Flush the toilet to empty the tank and remove any remaining water using a towel or bucket.

Step 3: Disconnect the Water Supply Line

Using an adjustable wrench, disconnect the water supply line from the bottom of the tank. Place a bucket underneath to catch any water that may drip out. Now, remove the tank from the bowl by unscrewing the bolts connecting them.

Step 4: Remove the Old Toilet

Next, you need to remove the old toilet. Start by removing the caps covering the bolts at the base of the toilet. Then, use a wrench to unscrew the nuts and carefully lift the toilet bowl off the floor. Use a putty knife to scrape off any remaining wax from the flange.

Step 5: Install the New Wax Ring and Bolts

Place the new wax ring on the flange, ensuring it is properly aligned. Insert new bolts into the slots on the flange, making sure they are secure. Apply plumber’s tape to the bottom of the bolts to prevent leaks.

Step 6: Install the New Toilet

Now it’s time to install the new toilet. Carefully lower the toilet bowl onto the wax ring, aligning the bolts with the holes in the base. Gently press down to create a seal. Place washers and nuts onto the bolts and tighten them, being careful not to overtighten and crack the toilet.

Step 7: Reconnect the Water Supply

Finally, reconnect the water supply line to the bottom of the tank and turn on the water valve. Check for any leaks and tighten the connections if necessary. Give the toilet a test flush to ensure everything is working correctly.
