A fresh bathroom is one of the most satisfying upgrades you can make to a home. But the parts you see, the tile and the vanity, only last if the plumbing behind the walls is done right first.
Plan Your Layout Before You Buy Anything
The biggest plumbing cost in a reno is moving things around. Drains, vents, and supply lines are not always easy or cheap to relocate, especially in older Aurora and Newmarket homes. Decide early whether you are keeping the existing layout or moving the toilet, tub, or sink. Keeping fixtures roughly where they are will save you money and time. If you do want to move them, get a plumber to confirm what is realistic before you fall in love with a design.
Sort Out Supply and Drainage
The unglamorous stuff matters most. Before the pretty finishes go in, make sure these are handled:
- Shut-off valves for the toilet and sink so future repairs are easy
- Properly sized drain lines so showers and tubs empty quickly
- Adequate venting so drains do not gurgle or smell
- Water pressure that can handle a rain shower head if that is on your wish list
Getting these right now prevents slow drains and weak showers later, when fixing them means tearing open a finished wall.
Think About Water Heating
A bigger soaker tub or a high-flow shower can outpace an older water heater. If you are upgrading fixtures, it is worth asking whether your current water heater can keep up. Sizing this correctly during the reno is far easier than discovering halfway through a shower that the hot water has run out.
Choose Fixtures That Match Your Plumbing
Not every beautiful fixture fits every setup. Wall-mounted faucets, for example, need rough-in plumbing inside the wall. Some toilets need a specific rough-in distance. Bring your fixture choices to your plumber early so they can confirm compatibility and order the right valves and connectors. A quick check now avoids return trips and delays later.
Do Not Skip the Permits and Pros
Major plumbing changes often require a permit, and for good reason. Proper inspection protects you and the next owner of your home. A licensed plumber handles this correctly, ensures the work meets code, and stands behind it. Tackling supply and drain work yourself can lead to leaks hidden behind brand new tile, which is the worst place to find one.
