Bathroom & Kitchen Plumbing Remodel in Ontario

A bathroom or kitchen remodel is one of the few plumbing jobs where the pipe work and the finished look have to come together at the same time. It usually means relocating or adding supply and drain lines for a new tub, shower, vanity, toilet, sink, dishwasher, or fridge line, then tying all of that into the existing stack without leaving the rest of the house short on pressure or venting. On older Ontario homes this often turns up surprises: galvanized supply lines that need full replacement, cast iron drains that have to be cut and adapted to PVC or ABS, or a stack vent that was never up to code in the first place. A contractor who only does hookups and can't read a rough-in drawing or pull the right permit is going to cost you more once the drywall goes back up.

We list 29 businesses in this category. When you're comparing them, look past the quote total and check who is pulling permits, who is warrantying both labor and fixtures, and who can show recent remodel photos rather than just repair work. Our scoring weighs licensing, insurance, review consistency, and how a company handles the messier parts of a remodel, not just how fast they answer the phone.
