Step 1: Turn off the water supply 

The first step is to turn off the water supply to your toilet. You can do this by locating the valve at the back of the toilet and turning it in a clockwise direction. 

Step 2: Empty the tank and bowl 

Next, flush the toilet to empty the remaining water from the tank and bowl. Use a plunger to get rid of any excess water in the bowl. 

Step 3: Identify the source of the leak 

Once you have removed the excess water, use a towel to wipe the base of the toilet dry. Check for any cracks or damages to the toilet base. If there are none, then the wax ring is the culprit. 

Step 4: Tighten the bolts and screws 

Carefully inspect all the bolts and screws holding the toilet base to the flange. Tighten them firmly, but don’t overtighten as it can crack the porcelain base. 

Step 5: Replace the wax ring 

Here comes the trickiest part of the process, replacing the wax ring. Use the putty knife to scrape off any remaining wax from the flange. Then, place the new wax ring over the drain flange and lower the toilet base onto it. Finally, tighten the bolts and screws, carefully ensuring that the toilet is levelled and sits firmly on the floor.
