These comparisons put the most common plumbing choices side by side, with a table of the main differences and plain guidance on which option fits which situation, using sourced cost ranges where we have them.
How to use a comparison
Read the table, then the "which is right" section. Then talk it through with the provider on the call, because the condition of your home's pipes, gas line and space often decides it. Each comparison links to the related service pages and cost guides.
