Upgrading your bathroom with a new toilet can make a significant difference in both aesthetics and functionality. If you’re considering installing a new Gerber Viper 10″ rough toilet, you’re in for a modern and efficient addition to your bathroom space. In this blog, we’ll walk you through the step-by-step process of installing this innovative toilet model, ensuring a smooth and successful installation.

Step 1: Gather Your Tools

Before you begin, gather the necessary tools and materials. You’ll need a wrench, a screwdriver, a wax ring, toilet bolts, a level, and a bucket.

Step 2: Remove the Old Toilet

Start by turning off the water supply and flushing the old toilet to empty the tank. Remove the nuts from the toilet bolts and carefully lift the toilet off the floor. Scrape off the old wax ring and inspect the flange for any damage.

Step 3: Install the Wax Ring

Place a new wax ring onto the flange, ensuring it’s centered and secure.

Step 4: Position the New Toilet

Position the Gerber Viper toilet over the wax ring and flange, aligning the toilet bolts with the mounting holes on the toilet base. Gently press down to compress the wax ring and create a seal.

Step 5: Secure the Toilet

Place washers and nuts onto the toilet bolts and hand-tighten them. Use a wrench to tighten the nuts evenly, but be cautious not to overtighten, as it could crack the toilet base.

Step 6: Level and Tighten

Place a level on the toilet bowl to ensure it’s perfectly level. If needed, adjust the toilet by tightening or loosening the nuts on the toilet bolts.

Step 7: Connect the Water Supply

Connect the water supply line to the fill valve on the toilet tank. Turn on the water supply and check for any leaks.

Step 8: Test the Flush

Flush the toilet a few times to ensure that it’s flushing properly and there are no leaks around the base.


Installing a new Gerber Viper 10″ rough toilet is a straightforward process that can elevate the look and functionality of your bathroom. By following these steps and taking your time to ensure a proper installation, you’ll enjoy the benefits of a modern and efficient toilet that adds value to your home.
