Bathroom Renovation Cost Guide for Ontario Homeowners: 2026

By D&D Interior Services Team January 1, 2026 5 min read Blog

Bathroom renovation costs vary widely by scope and quality. Here's a realistic guide for Ontario homeowners.

Planning Your Renovation

Bathroom renovation costs in Ontario are highly variable, depending on the scope of changes, the size of the room, material quality, and whether structural or plumbing changes are involved. Accurate budgeting requires understanding the cost structure.

Entry-level bathroom refresh ($5,000-10,000): cosmetic update without moving plumbing or tile — new fixtures (toilet, faucets, lighting), fresh paint, new accessories, possibly a new vanity. For small bathrooms, this scope is achievable.

What the Process Looks Like

Mid-range bathroom renovation ($15,000-30,000): full retile of floor and walls, new vanity, new toilet, new tub/shower fixture, new lighting, mirror, and accessories. May include like-for-like plumbing replacement. Standard to mid-grade materials.

High-end bathroom renovation ($35,000-75,000+): significant layout changes (expanding the room, moving plumbing, adding a second sink), premium tile, custom vanity, freestanding tub, walk-in shower with multiple fixtures, heated floor, and premium finishes throughout.

Working With D&D Interior Services

Cost allocation by component: tile and labour typically represent 30-40% of total cost; plumbing fixtures and installation 20-25%; vanity and countertop 15-20%; shower glass and hardware 10-15%; electrical, painting, and accessories comprise the remainder.

Common scope expansions that significantly increase cost: converting a tub to a walk-in shower, adding a second vanity, expanding the room by borrowing adjacent space, radiant floor heating. Each adds cost that may not be initially included in conceptual estimates.

Permit costs and requirements: plumbing changes, electrical work, and structural modifications require building permits in most Ontario municipalities. Include permit fees (typically $500-1,500 for a bathroom) in the project budget.
