Installing a Toilet Flange on a Concrete Floor
Installing a toilet flange on a concrete floor might seem like a daunting task, but with some preparation and the right tools, it's manageable for even a novice DIYer. Whether you're upgrading your bathroom floor or starting from scratch, this guide will help you get the job done right.
Choosing the Right Flange
The first step is selecting the correct flange for your project. It's tempting to save a few dollars on cheaper options, but investing in a high-quality flange with a stainless steel (SS) ring is worth it. Unlike painted plain steel, SS rings are durable and resist rust, which is particularly important in a moisture-prone bathroom environment.
When deciding on the flange type, consider whether to use one with or without a socket. A socket-less flange is more user-friendly because you can leave the pipe long, install the flange on the finished floor, and trim the excess pipe later. Flanges with sockets require pre-measuring and precise cutting of the PVC pipe, which can be challenging without experience.
Preparing the Surface
Start by ensuring the concrete floor is clean and level where the flange will sit. Cleaning both the PVC pipe and flange with a cleaner or primer is equally important to remove any dirt or debris. This step is essential for a strong and lasting connection.
Getting the Flange to Sit Flat
One of the most common issues when working with concrete floors is ensuring the flange sits flush against the surface. If your flange doesn’t seat properly, here are some options:
- Use spacers to fill any gaps between the flange and the floor.
- Trim the lower portion of the flange pipe for a better fit.
Additionally, make sure the flange is installed at the right height to account for the finished flooring, such as tile, ensuring a leak-free toilet installation.
Securing the Flange
To securely anchor the flange to the concrete, use a masonry drill bit to pre-drill holes for the screws. Opt for stainless steel screws to prevent rust over time. For extra stability, you can epoxy the screws into the concrete, which creates a strong and durable hold.
The number of holes on the flange may vary by brand, but as a rule of thumb, use all the screw holes or at least those adjacent to the toilet anchor bolts for maximum support.
Steps for Final Installation
Here’s a simple breakdown of the steps:
| Step | Description | Tools/Materials Needed |
|---|---|---|
| 1 | Clean pipe and flange | Cleaner/Primer |
| 2 | Apply PVC cement to both surfaces | PVC cement |
| 3 | Twist flange into place | |
| 4 | Secure flange with screws | Masonry drill, stainless steel screws |
By following these steps, you’ll ensure a secure and sturdy toilet flange installation that will stand the test of time.

Frequently Asked Questions
How do I install a toilet flange on a concrete floor?
To install a toilet flange on a concrete floor, start by removing the old flange, cleaning the area, and selecting the correct new flange. Position the flange over the drainpipe, drill holes into the concrete, and secure it using concrete screws like Tapcons. Ensure the flange sits level and flush with the finished floor before attaching the toilet.
What tools are needed to install a toilet flange on concrete?
You will need a hammer drill with a masonry bit, Tapcon screws (or similar concrete screws), a screwdriver, a wrench, a putty knife, and a new toilet flange. Depending on your project, you might also need hydraulic cement or a leveling compound for repairs.
Should a toilet flange be flushed with the floor?
Yes, the toilet flange should sit flush with the finished floor surface for proper installation. This ensures a tight seal and prevents leaks. If the flange is too high or low, you may need to adjust by using spacers or leveling compounds.
Can I install a toilet flange without drilling into concrete?
Drilling into the concrete is recommended for a secure installation. However, you can use hydraulic cement to fill the void and embed screws directly into the wet cement. Once cured, the screws will hold the flange in place.
What type of screws should I use for securing a toilet flange to concrete?
Tapcon screws or any type of concrete screws are ideal for securing a toilet flange to a concrete floor. They provide strong anchoring and are specifically designed to work with masonry surfaces efficiently.
