Introduction to Floor Mounted One Piece Toilets


Floor mounted one piece toilets are known for their sleek design and ease of cleaning. Unlike two-piece toilets, where the tank and bowl are separate, a one piece toilet consolidates both components into a single unit. This not only gives your bathroom a modern look but also reduces the number of crevices where dirt can accumulate.
In this guide, we will break down the entire installation process into manageable steps, ensuring that whether you're a seasoned DIYer or a novice, you can confidently install your new toilet.

Essential Tools and Materials for Installation


Before starting your toilet installation, gather the necessary tools and materials to make the process smoother. Here’s a comprehensive list:

Tools Needed


- Adjustable wrench
- Screwdriver (flathead and Phillips)
- Level
- Tape measure
- Plumber's putty
- Caulk gun
- Bucket
- Towels or rags

Materials Required


- Floor mounted one piece toilet
- Wax ring seal
- Toilet bolts and nuts
- Water supply line (if not included)
Having all the required tools and materials on hand will save you time and frustration during the installation process.

Pre-Installation Checks: Preparing Your Bathroom


Before beginning your installation, it’s crucial to assess your bathroom environment. Here are some essential checks:

Check Existing Plumbing


Ensure that the plumbing is in good condition. Look for any leaks or signs of corrosion that may affect the installation.

Measure Your Space


Measure the distance from the wall to the center of your toilet flange. This is typically 12 inches but can vary. Knowing this measurement ensures that the new toilet will fit properly.

Choose the Right Height


Select a toilet height that suits your comfort. Standard height toilets are 15 inches from the floor to the bowl rim, while comfort height toilets are 17 to 19 inches, catering to taller individuals or those with mobility issues.

Removing the Old Toilet: Step-by-Step


Removing your old toilet is the first step toward installing your new floor mounted one piece toilet. Follow these steps:

Step 1: Shut Off the Water Supply


Locate the shut-off valve on the wall behind the toilet and turn it clockwise to stop the water flow.

Step 2: Drain the Toilet


Flush the toilet to empty the tank and bowl. Use a bucket or towels to soak up any remaining water in the tank.

Step 3: Disconnect the Water Supply Line


Loosen the nut connecting the water supply line to the bottom of the tank using your adjustable wrench.

Step 4: Remove the Toilet Bolts


Locate the bolts securing the toilet to the floor, usually covered by plastic caps. Remove the caps, then use a socket wrench to unscrew the bolts.

Step 5: Lift the Old Toilet


Carefully rock the toilet back and forth to break the wax seal, then lift it straight up and away from the floor. For safety, have someone assist you in this step.

Installing Your New Floor Mounted One Piece Toilet


Now that the old toilet is removed, it’s time to install your new one piece toilet. Follow these steps:

Step 1: Prepare the Flange


Inspect the toilet flange for damage. If it’s cracked or broken, replace it before proceeding. Clean any old wax from the flange and the floor.

Step 2: Install the Wax Ring


Place the new wax ring on the flange, ensuring it’s centered. This ring creates a seal to prevent leaks.

Step 3: Position the Toilet


Carefully lower the new toilet onto the wax ring, aligning the toilet's base with the flange. Press down firmly to ensure a good seal.

Step 4: Secure the Toilet


Insert the toilet bolts through the holes in the toilet base and tighten the nuts. Be cautious not to overtighten, as this can crack the porcelain.

Step 5: Level the Toilet


Use a level to check that the toilet is even. Adjust the bolts as necessary to achieve a stable position.

Connecting the Water Supply: A Complete Guide


Now that your toilet is securely in place, it’s time to connect the water supply.

Step 1: Attach the Water Supply Line


Connect the water supply line to the tank, ensuring a snug fit. Use pliers to tighten the connection if necessary, but avoid overtightening.

Step 2: Turn on the Water Supply


Slowly turn the shut-off valve counterclockwise to restore water flow to the toilet.

Step 3: Check for Leaks


Inspect the connections for any leaks, tightening them as necessary. Use towels to wipe away any spills and monitor for continued leaks.

Testing Your New Toilet Installation


Once everything is connected, it’s time to ensure your new toilet is functioning correctly.

Step 1: Flush the Toilet


Flush your new toilet to check for proper operation. Observe the water level in the tank and bowl; it should fill to the appropriate mark.

Step 2: Check for Any Issues


Listen for unusual sounds and watch for leaks around the base and connections. If you notice any issues, address them immediately.

Maintenance Tips for Longevity


To ensure your floor mounted one piece toilet remains in excellent condition, follow these maintenance tips:

Regular Cleaning


Use a gentle cleaner specifically designed for toilets to avoid damaging the finish. Avoid harsh chemicals that can corrode the parts.

Inspect the Toilet Periodically


Routine inspections can catch any issues early. Look for signs of leaks, cracks in the porcelain, or mineral buildup in the tank.

Adjust the Water Level as Needed


If you find that the toilet flushes poorly or is excessively noisy, adjusting the water level in the tank can help optimize performance.
