Wax Rings vs. Rubber Seals: Which Toilet Seal Is Best?

Wax Rings vs. Rubber Seals: Which Toilet Seal Is Best?

When it comes to installing or replacing a toilet, one of the most important components is the seal that connects the toilet to the drainpipe. This seal prevents leaks, keeps sewer gas from escaping, and ensures a long-lasting installation.

The two main options are traditional wax rings and modern rubber seals. At Revelation Plumbing, we’ve worked with both—but time and again, we choose wax rings.

Here’s why.

What Is a Wax Ring?

A wax ring is a tried-and-true method that’s been used for decades in plumbing. It’s a thick ring of sticky wax that compresses between the bottom of the toilet and the flange on the floor. When properly installed, the wax creates an airtight and watertight seal that can last for decades.

✅ Pros of Wax Rings:

• Proven track record of reliability

• Creates a strong, airtight, and watertight seal

• Inexpensive and widely available

• No moving parts to fail over time

⚠️ Cons of Wax Rings:

• Can’t be reused once compressed

• Messier to install compared to rubber options

• Improper installation can cause leaks

What Is a Rubber Seal?

Rubber toilet seals are a newer alternative to wax. They’re made of flexible rubber or foam material and often come with a flange or gasket system that snaps into place.

✅ Pros of Rubber Seals:

• Cleaner and easier installation

• Can sometimes be repositioned or reused

• More forgiving if the toilet has to be removed and reset

⚠️ Cons of Rubber Seals:

• More expensive than wax rings

• Not always compatible with every flange or toilet design

• Rubber can degrade, harden, or warp over time

• Easier to knock out of place during installation

• 
  

Why Revelation Plumbing Prefers Wax Rings

At Revelation Plumbing, we prioritize longevity and reliability. While rubber seals might be trendy and convenient for DIY projects, they don’t always stand the test of time—especially in Pittsburgh homes where we see older plumbing systems and unique installation conditions.

We prefer wax rings because:

• They rarely fail when properly installed. Wax has been trusted for generations, and it simply works.

• They handle imperfections better. Uneven floors, old flanges, or slight gaps can compromise a rubber seal, but wax molds perfectly into place.

• They’re cost-effective for homeowners. A wax ring is inexpensive yet provides premium performance when installed by a professional.

In short: rubber seals might be the convenient option, but wax rings are the dependable option—and that’s why we stand behind them.

Bottom Line: Which Should You Choose?

If you’re tackling a quick DIY toilet reset and want something easy, a rubber seal might seem appealing. But if you want a professional installation that’s built to last, Revelation Plumbing recommends—and uses—wax rings.

We know that when your toilet is sealed with a wax ring by our licensed technicians, you won’t have to worry about leaks, odors, or premature failure. It’s one of those small choices that makes a big difference in protecting your home.
