How to install a new toilet?
Leave a message
Hey there! If you're looking to spruce up your bathroom or replace an old, malfunctioning toilet, you've come to the right place. As a toilet supplier, I've seen it all when it comes to toilet installations, and I'm here to walk you through the process step by step. Installing a new toilet might seem like a daunting task, but with the right tools and a bit of know-how, you can do it yourself and save some money in the process.
Step 1: Gather Your Tools and Materials
Before you start tearing out the old toilet, make sure you have all the necessary tools and materials on hand. Here's a list of what you'll need:
- New toilet (you can check out our Two Piece Macerating Toilet, Best Marine Portable Toilet, or Electric Boat Toilet for some great options)
- Wax ring
- Closet bolts and nuts
- Adjustable wrench
- Screwdriver
- Plunger
- Bucket
- Measuring tape
- Putty knife
- Level
Step 2: Turn Off the Water Supply
The first thing you need to do is turn off the water supply to the old toilet. You'll usually find a shut-off valve located on the wall behind the toilet. Turn the valve clockwise until it stops to shut off the water.
Step 3: Drain the Toilet
Flush the toilet to drain as much water as possible from the tank and bowl. Then, use a plunger to remove any remaining water from the bowl. You can also use a bucket to scoop out the water if necessary.


Step 4: Disconnect the Water Supply Line
Use an adjustable wrench to loosen the nut connecting the water supply line to the bottom of the toilet tank. Once the nut is loose, you can pull the water supply line away from the tank.
Step 5: Remove the Old Toilet
Locate the closet bolts at the base of the toilet. These bolts hold the toilet in place. Use a wrench or pliers to loosen the nuts on the closet bolts. Once the nuts are loose, you can lift the toilet off the floor. Be careful, as the toilet can be heavy and awkward to handle.
Step 6: Clean the Floor
Use a putty knife to scrape away any old wax or debris from the floor flange. Make sure the flange is clean and level before installing the new toilet.
Step 7: Install the Wax Ring
Place the wax ring on the floor flange. The wax ring creates a seal between the toilet and the drain pipe. Make sure the wax ring is centered on the flange.
Step 8: Position the New Toilet
Carefully lower the new toilet onto the wax ring and align the holes in the base of the toilet with the closet bolts on the floor. Make sure the toilet is level by using a level. If the toilet is not level, you can adjust it by placing shims under the base of the toilet.
Step 9: Secure the Toilet
Once the toilet is in position, place the nuts on the closet bolts and tighten them with a wrench. Be careful not to overtighten the nuts, as this can crack the toilet.
Step 10: Reconnect the Water Supply Line
Attach the water supply line to the bottom of the toilet tank and tighten the nut with an adjustable wrench. Make sure the connection is tight to prevent leaks.
Step 11: Fill the Toilet Tank
Turn on the water supply valve to fill the toilet tank. Check for any leaks around the water supply line and the base of the toilet. If you notice any leaks, tighten the connections or replace the washers as needed.
Step 12: Test the Toilet
Flush the toilet to make sure it is working properly. Check the water level in the tank and the bowl to make sure they are at the correct levels. If the toilet is not flushing properly, you may need to adjust the float valve or the flapper.
Tips and Tricks
- Make sure you measure the rough-in distance before purchasing a new toilet. The rough-in distance is the distance from the wall to the center of the drain pipe. Most toilets are available in 10-inch, 12-inch, and 14-inch rough-in sizes.
- If you're installing a toilet on a second floor or in a mobile home, you may need to use a special type of wax ring or a no-wax gasket to prevent leaks.
- If you're having trouble removing the old toilet, you can try using a lubricant to loosen the nuts on the closet bolts.
- When installing the new toilet, make sure you follow the manufacturer's instructions carefully. Different toilets may have different installation requirements.
Conclusion
Installing a new toilet is a relatively simple DIY project that you can do in a few hours with the right tools and materials. By following these steps, you can save money on installation costs and have a new, functioning toilet in no time.
