Toilet Bowl Extra Thick Wax Ring with Brass Bolts - Strong Seal

In this review the LASCO Toilet Bowl Extra Thick Wax Ring is evaluated for homeowners and plumbers who need a dependable seal when installing or replacing a floor mount toilet. The bottom line: this wax ring is aimed at anyone who wants a straightforward installation and a reliable, gas- and water-tight connection between the toilet bowl and waste line, with the standout feature being the reinforced urethane core and polyethylene flange that help position the gasket for 3-in and 4-in drains.

Key Features

• Extra thick wax gasket: Provides generous sealing material to fill gaps and irregularities between the toilet base and the flange, reducing the chance of leaks.
• Brass bolts included: Comes with brass bolts to secure floor mount toilets and avoid corrosion or thread strip issues common with cheaper hardware.
• Reinforced urethane core: Adds structural support to the wax ring so it compresses evenly and maintains a durable seal under the toilet weight.
• Polyethylene flange: The sleeve fits both 3-in and 4-in waste lines and helps center the gasket over the drain for consistent placement during installation.
• Gas and odor tight: Designed to form a seal that prevents sewer gases and odors from escaping into the bathroom while also keeping water contained.
• Easy installation: Packaging includes how-to instructions and the design simplifies alignment and placement for DIYers and pros alike.

Who It's For

This product suits homeowners replacing a toilet, property managers maintaining multiple bathrooms, and professional plumbers who prefer a wax-based gasket with reinforced support. The polyethylene sleeve makes it especially useful when the drain opening might accept either a 3-in or 4-in fitting, reducing the need to stock multiple ring types.

Those who need a specialized high-rise flange, a non-wax seal, or have unusual flange heights should consider alternatives, as this is a traditional wax-based solution meant for standard floor mount toilets and common waste line sizes.

Pros & Cons

Cons
