Installing a western toilet involves a few basic steps. Here's a general guide to help you install a new western toilet:

1. Remove the old toilet: Before you install the new toilet, you'll need to remove the old one. Turn off the water supply to the toilet, and then flush the toilet to drain as much water as possible. Disconnect the water supply line from the tank and then remove the nuts and bolts that hold the toilet to the floor. Lift the toilet off the floor and set it aside.

2. Prepare the installation area: Clean the installation area where the old toilet was located, and then inspect the toilet flange. If it's damaged or broken, replace it before you proceed.

3. Install the wax ring: Place a new wax ring on the flange, making sure the tapered end is facing the toilet bowl.

4. Install the new toilet: Carefully lower the new toilet onto the wax ring, making sure the bolts in the flange line up with the bolt holes in the base of the toilet. Press down on the toilet to compress the wax ring, and then hand-tighten the nuts onto the bolts. Make sure the toilet is level, and then tighten the nuts using a wrench.

5. Connect the water supply: Reconnect the water supply line to the tank, hand-tightening the connection. Turn on the water supply valve and check for any leaks.

6. Test the toilet: Flush the toilet a few times to make sure it's working correctly. Check for any leaks around the base of the toilet or the water supply line.

That's it! By following these steps, you should be able to install a new western toilet.
