We are looking to buy a house that has two sinks in the bathroom. One is a great sink and prefer to put a shower in the corner. What is an estimate of what it would cost from sink plumbing is already established. I was so happy to find this – to get an idea of the costs, you will have to make a trip to your local store of home improvement and the price of the box and accessories that suit your taste and budget . You will find a big price difference based on how elaborate you are willing to go. Then the computer has to be installed. Do you have the experience and tools to do this? Maybe a professional should be brought in. He Plumbing is easy to understand but hard to do.
