What is a realistic budget for a bathroom renovation?
For a standard main bathroom in Sarnia, plan on $15,000 to $30,000 for a full renovation. Set aside another 10% to 15% for surprises behind the walls, like rot or old plumbing, which are common in homes built before 1980. A tub replacement or a tub-to-shower conversion alone costs much less.
Can I renovate a bathroom for $5,000?
You can refresh a bathroom for about $5,000, but not fully renovate one. That budget covers a new vanity, toilet, faucet, mirror, lighting and paint, or a basic tub swap. New tile, a new shower or moving plumbing pushes the cost past $10,000.
How long does a bathroom renovation take?
Most full bathroom renovations take two to four weeks once work starts. A tub-to-shower conversion takes three to seven days. A large ensuite can take three to five weeks. Ordering every fixture before tear-out keeps the bathroom out of use for the shortest time.
Do I need a permit to renovate a bathroom in Sarnia?
Swapping fixtures in the same spots usually doesn't need a permit. Adding a bathroom, moving drains, adding new plumbing or taking out walls usually does. The City of Sarnia and the townships around it each set their own process. Your contractor should check and pull any permit for you.
Can I use my bathroom during the renovation?
Usually not, once tear-out starts. If it's your only bathroom, ask your contractor about planning the work so the toilet is back in place each night. Ordering everything ahead of time shortens the time you're without a bathroom.
