How Much Does a Small Bathroom Remodel Cost?
On average in 2025, a small bathroom remodel costs $115 to $300 per square foot, or roughly $3,000 to $15,000 total. Half-bath remodels typically cost less because they do not require tub or shower updates. When planning your project, think in terms of cost per square foot. Your room size determines how much flooring, tile, paint, and the number of fixtures you’ll need.
Cost Per Square Foot
Most small bathroom remodels fall between $115 and $300 per square foot. This estimate includes materials, demolition, labor, fixtures, and installation. Premium materials like stone tile or custom cabinetry can push costs toward the higher end.

The size of your bathroom is one of the biggest cost factors. Below is a general breakdown of typical remodel costs by common small bathroom dimensions.

How to Save Money on a Small Bathroom Remodel
- Create a Realistic Budget: Start with the average cost range of $3,000 to $15,000 and adjust based on your bathroom’s size, layout, and preferred finishes.
- Use the Existing Bathroom Layout: Keeping plumbing and electrical in place reduces costs significantly and avoids major structural work.
- Select Mostly Mid-Range Fixtures: Mid-tier materials offer good durability and lower maintenance without the high price of luxury finishes.
- Splurge Selectively: Because the space is small, you can upgrade a few premium items — such as tile or hardware — without overspending.
- Do Some of the Work Yourself: DIY tasks like demolition, painting, or installing simple fixtures can lower labor expenses.
- Know When to Hire the Pros: Plumbing and electrical work should be handled by licensed professionals to ensure safety and code compliance.
