Leaky faucets, leaky shower heads and clogged drains are common shower problems that develop over time. These are usually caused by a single worn piece; replacing these worn pieces saves you from replacing the entire shower and prevents further damage. In addition to wasting and discolouring water, leaky showers and clogged shower drains may damage bathroom walls and floors, which further adds to the repair cost. Shower repair parts and repair kits can be purchased at most home improvement and plumbing supply stores. Homeowners with plumbing knowledge may choose to do the repairs themselves.
