We have two toilets that are leaking because the flange is about 2 inches lower than the flooring. A plumber came out and put in three wax seals on each toilet, but it is still leaking. I asked the plumber to come back out and to give another bid to fix it and he wants $3200 to remove the concrete and put in a new flange. That is outrageous to me and I cannot begin to pay that. He says that the toilet will shift slightly and break any seal if we try to use an extender. Can anyone help me come up with a solution ?
Take 2 inch plywood, or two 1 inch plywood
Cut it in a circle (so it looks like doughnut) and it fits over the toilet drain.
Screw it in the concrete floor with concrete screws, you need 3 screws, but make sure they are not in the way of toilet ring mounts.
Screw in the toilet mount ring in place followed by wax seal.
You might need a toilet drain pipe extender that could look like this to bring the drain pipe closer to the toilet.
