Start by budgeting for plumbing fixtures like sinks and toilets, which can range from $200 to $800 each, alongside electrical wiring costs averaging $500 to $1,500 for safe installation. You’ll also need to account for flooring tiles, typically costing $2 to $10 per square foot, depending on the style and durability you choose.
Plumbing Fixtures
Deciding on plumbing fixtures for a garage bathroom starts with understanding the essential components and their associated costs. You’ll need a sink, toilet, and possibly a shower, each with specific price ranges based on quality.

Factor in additional parts like faucets ($20–$100) and drain hardware ($10–$30). Choose durable materials to avoid frequent replacements, and stick to your budget by comparing local supplier prices before purchasing.
Electrical Wiring Costs
Moving from plumbing needs to another key aspect of your garage bathroom project, let’s focus on the costs tied to electrical wiring. You’ll need to budget for materials and labor.

Plan the layout first, ensuring compliance with local codes. Hiring a licensed electrician might cost $200-$400 for safety and precision.
Flooring Tiles Cost
Shifting to the ground beneath your feet, let’s break down the costs of flooring tiles for your garage bathroom project. Tiles guarantee durability and moisture resistance, critical for bathroom spaces.
Tile Cost Breakdown
- Ceramic Tiles: $1–$5 per square foot, affordable and common.

Contractor Hiring Expenses
When tackling contractor hiring expenses for adding a bathroom to your garage, start by comparing installation costs across different professionals. You’ll find that labor costs can vary widely based on factors like experience, location, and project complexity. Consider how these elements, such as a contractor’s hourly rate or regional pricing trends, impact your overall budget.

Compare quotes from at least three contractors. Check their portfolios for similar garage projects. Confirm they’ve got proper licensing. Don’t rush; review each bid carefully to understand inclusions like plumbing or tiling before you sign any contract.
Factors Impacting Labor Costs
Moving from the general cost estimates of bathroom installation, let’s focus on what specifically drives labor expenses when hiring contractors for your garage project. Labor costs vary based on key factors.
