I have leaking toilet drain pipe. The plumber inspected subfloor area today and advised that we had old style cast iron drain pipes and some of them are not connected properly. The toilet pipe has also got leakage.
He quoted $5000 including GST to install all new drain pipes for vanity, shower and toilet. He will also connect it to the sewer which is running close to the toilet however it requires taking out concrete. They will put a new concrete after installation.
Is it reasonable cost to install new drainage for bathroom?
Call in another plumber and tell him what needs to be done and obtain a second quote. Don't tell him the first quote is $5,000 otherwise he will just quote you slightly lower. The second quote will be your best guide.
