The decision to install a new toilet can often boil down to a question of expertise and comfort level with DIY projects. While hiring a professional plumber ensures a job done right, installing a toilet yourself could be a cost-effective alternative if you have some basic plumbing knowledge and a helpful guide at hand. In this plumbing guide, we will explore both options so you can make an informed decision.

Understanding the Process of Toilet Installation

Before deciding whether to DIY or hire a plumber for your toilet installation, it is important to understand the process involved. The steps for installing a new toilet typically include removing the old toilet, preparing the area, assembling and attaching the new toilet, and connecting it to the plumbing system.

To further dissect the toilet installation process, let’s begin with the first step — removing the old toilet. This includes shutting off the water supply, draining the tank and bowl, and unscrewing the bolts that secure the toilet to the floor. It’s essential to be careful during this process to prevent any water leakage or damage to the flooring.

The second step involves preparing the area for the new toilet — a clean, smooth surface is crucial for the toilet to sit evenly. This stage might also include leveling the floor, if necessary, and cleaning the flange, the component that connects the toilet to the drain pipe.

Next, comes the toilet’s assembly, which includes attaching the tank to the bowl, installing the toilet seat, and applying the wax ring on the base of the toilet. This step requires careful attention to the manufacturer’s instructions to ensure correct assembly.

Finally, the new toilet is placed onto the flange, secured with bolts, and connected to the water supply. It’s crucial to check for any leaks in the system at this stage. If everything is done correctly, you should have a functioning toilet.

During this process, you may encounter challenges such as corroded bolts and pipes, uneven flooring, or incorrect measurements. It is crucial to have the necessary tools and knowledge to handle these potential obstacles.

It is essential to consider your budget and compare prices before making a decision. Keep in mind that if any issues arise during the DIY process, you may end up spending more money on repairs.
