A bathroom remodel can easily cost $10,000 to $50,000+, making contractor insurance non-negotiable before you hand over your first payment. Without proof of proper coverage, you're financially exposed if someone gets injured on your property or your contractor damages your home during the job. Here's exactly what you need to verify before hiring.
Why Insurance Matters in Bathroom Remodeling
Bathroom projects involve water lines, electrical work, tile cutting, and structural demolition—all high-risk activities. A contractor without liability insurance could leave you responsible for medical bills if their worker falls and breaks an arm. Similarly, if they flood your living room while installing your new shower valve, you'll be stuck paying for water damage repairs out of pocket.
Beyond liability, bathroom work often requires workers' compensation insurance. This covers employee medical costs if someone gets hurt on the job, which is legally required in most states for contractors with employees (rules vary by state; check your local requirements).
What Types of Insurance to Look For
General Liability Insurance is the baseline. This typically covers property damage, bodily injury, and medical expenses. For bathroom remodeling, verify the policy limit is at least $1 million per occurrence—this covers your specific project if something goes wrong.
Workers' Compensation Insurance is mandatory in most states if the contractor has employees. Ask for proof of this coverage; a contractor who skips it is cutting corners elsewhere and likely on jobs.
Builders Risk Insurance or Installation Floaters protect against damage to your home during the renovation itself. This is especially critical in bathroom work because water damage is a real concern. Not all contractors carry this, but asking shows you know what's important.
How to Request and Verify Coverage
Ask directly. When you contact contractors for quotes, simply say: "Please provide proof of current general liability and workers' comp insurance before we proceed." Reputable contractors have this ready—if they get defensive or vague, that's a red flag.
Request certificates of insurance. Ask them to send you a Certificate of Insurance (COI) directly from their insurance provider, not a copy from the contractor. The COI should show:
- The contractor's name and your address (listed as "additional insured" when relevant)
- Policy numbers and expiration dates
- Coverage limits (look for minimums of $1M general liability)
- The insurer's name and contact information
- Effective dates that cover your entire project timeline
Verify with the insurer. If you want to be thorough, call the insurance company listed on the certificate to confirm the policy is active. This takes five minutes and prevents surprises.
Check licensing boards. Contact your state or local licensing board (usually managed by your state's Department of Professional Regulation). Many jurisdictions maintain records of complaints against contractors and sometimes note insurance lapses.
Red Flags to Catch
If a contractor says they're "insured through their supplier" or "covered under a homeowner's policy," walk away. Those aren't acceptable substitutes for proper contractor insurance. Similarly, extremely low bids sometimes indicate the contractor is cutting corners—and skipping insurance is a classic way to undercut competitors.
Ask about their deductible too. Some contractors have $5,000 deductibles; if damage occurs, you might have to pay that out of pocket before insurance kicks in. Clarify this upfront.
Timeline Considerations
Request insurance documentation before signing contracts. Many contractors won't start work without their COI on file anyway, so this shouldn't be an obstacle. If your project spans several months (common for bathroom remodels), confirm the insurance is renewed before the project ends—expiration mid-project creates a gap.
Putting It Together
Compare contractors not just on price but on insurance transparency. A contractor who readily provides COIs and answers insurance questions is demonstrating professionalism. If you're comparing multiple bathroom contractors, platforms like Mercoly make it easier to gather quotes and compare coverage details alongside pricing and reviews.
When you hire someone without verified insurance, you're essentially betting your home and finances on their perfect execution. It's not worth the risk on a $25,000 bathroom renovation.
Frequently Asked Questions
Q: Do I need to add the contractor to my homeowner's insurance? Most homeowner's policies exclude contractor work, so this won't provide coverage. The contractor's general liability insurance is what protects you during the remodel.
Q: What if the contractor's insurance lapses mid-project? Stop work immediately until they provide proof of renewed coverage. Any damage that occurs without insurance in place becomes your financial responsibility.
Q: How much general liability coverage is enough for a bathroom remodel? Minimum $1 million per occurrence; some contractors carry $2 million, which is even better for larger or complex projects.
Use these steps before signing any contract, and you'll avoid costly surprises.
