Installing a tankless toilet in your bathroom is a great way to upgrade your space and enjoy the benefits of modern plumbing. This DIY guide will discuss the step-by-step process of installing a tankless toilet.  

Tools and Materials  

Before you begin, gather the necessary tools, including a wrench, screwdriver, and level. You'll also need the tankless toilet, wax ring, and water supply line. Remember to prioritize safety by wearing protective gloves and goggles.  

Preparation  

Start by shutting off the water supply to your toilet and removing the old fixture. Thoroughly clean the area to ensure a smooth installation process.  

Tankless Toilet Installation Steps

1. Positioning the Toilet Flange 

Align it with the drainpipe and secure it using screws or bolts.  

2. Connecting the Water Supply Line 

Attach the water supply line to the toilet's inlet valve, ensuring a tight connection.  

3. Attach the Tankless Toilet to the Floor 

Place the toilet over the flange, aligning the mounting holes. Secure it to the floor utilizing screws or bolts.  

4. Installing the Wax Ring 

Carefully place the wax ring on the flange, ensuring a proper seal between the toilet and the drainpipe.  

5. Securing the Toilet Bowl to the Flange 

Press the toilet bowl onto the wax ring, aligning the mounting holes. Secure it in place utilizing screws or bolts.  

6. Testing the Toilet for Leaks 

Turn on the water supply and flush the toilet multiple times to check for leaks. Adjust if necessary.  

Finishing Touches  

Once you've confirmed no leaks, adjust the water flow to the desired level. Apply a bead of caulk around the toilet's base to provide a finished look and prevent water seepage. Finally, thoroughly inspect and clean up any excess materials or debris.
