What a small bathroom budget usually includes
A realistic budget covers demolition and removal, a vanity and countertop, a toilet, a tub or shower update, tile and waterproofing, a faucet and fixtures, lighting, paint, and labour. Keep the existing layout and that list, along with the cost, stays predictable.
Costs climb once you move plumbing, convert a tub to a walk-in shower, or retile the whole room. Each of those adds labour and materials a basic refresh skips.
What drives the cost up or down
Finishes are the biggest lever you control. A basic vanity, standard tile, and mid-range fixtures cost far less than premium versions, so your material choices can swing the budget either way.
Labour, waterproofing, and any plumbing or structural change are where the total really rises. Older GTA homes can add cost too, since water damage or dated wiring often turns up once the walls are open.
How to set a realistic budget
Start with one decision: refresh or full renovation. That choice shapes what a bathroom renovation costs more than anything else. Then list the specific updates that matter most to you. A clear scope makes it much easier to land on a budget that reflects the work you actually want done.
