A bathroom remodel puts someone in your plumbing, your electrical, and your only working shower for days or weeks at a time. Picking the wrong contractor doesn't just cost money — it can leave you with a half-torn-out bathroom and no clear path to finishing it. Here's how to vet a bathroom remodeler before you sign anything.
Is the Remodeler Actually Licensed and Insured?
Start here, before you look at a single photo. Most states require a contractor license for work above a small dollar threshold, and you can verify it yourself through your state's licensing board rather than taking a contractor's word for it — see How Do I Check a Contractor's License? for links by state.
License status tells you the contractor is legally allowed to work. Insurance tells you what happens if something goes wrong. Ask for a certificate of insurance showing general liability coverage and, if they have employees, workers' compensation. If a worker is hurt in your bathroom and the remodeler has no workers' comp, you could end up named in a claim. Call the insurance agent on the certificate to confirm it's current — certificates can lapse or get forged.
How Do You Verify a Remodeler's Portfolio?
Photos on a website prove the remodeler has a camera, not that they did the work well. Ask for:
- Jobs similar in scope to yours — a full gut-and-reconfigure is a different skill set than a cosmetic refresh.
- At least two references from projects completed in the last 12 months, and actually call them. Ask what went wrong and how it was handled, not just whether they're happy.
- The name of the project's actual lead, since larger remodeling companies sometimes sell the job with their best crew and send a different one.
If a remodeler won't give you a recent reference, that's information. A business with a steady pipeline of satisfied clients usually has no problem connecting you with a couple of them.
How Many Bids Should You Get, and How Do You Compare Them?
Get at least three bids on the same defined scope of work — same fixtures, same finish level, same square footage. The FTC's guidance on hiring a contractor recommends getting multiple written estimates and treating a big gap between bids as a reason to ask questions, not a reason to pick the cheapest one automatically (FTC: How To Avoid a Home Improvement Scam). For more on why the lowest number isn't automatically the best deal, see Should You Always Take the Lowest Contractor Bid?.
This is really the core problem with hiring a remodeler off a single quote: you have no way to know if the number you got is fair. You're just hoping. Getting comparable bids from a few vetted pros is what turns that hope into an actual price check — you can see where one bid is padded, where another is missing line items, and negotiate from an informed position instead of a guess.
A simple way to line bids up side by side:
| What to Compare | Why It Matters |
|---|---|
| Scope of work | Confirms every bid covers the same job, not a stripped-down version |
| Materials and fixture allowances | A low bid often hides a low-grade fixture allowance |
| Payment schedule | Tied to completed milestones, not arbitrary dates |
| Timeline | Realistic start and finish windows, with what happens if it slips |
| License and insurance | Confirmed independently, not just claimed in the bid |
| Permit responsibility | Contractor should pull required permits, not leave it to you |
For typical dollar ranges by project size, see How Much Does a Bathroom Remodel Cost in 2026? and How Much Does a Small Bathroom Remodel Cost? — use those as a sanity check against the bids you get, not a substitute for getting them.
How Much Deposit Is Normal — and How Much Is Too Much?
Deposit limits vary by state, and some states cap them by law. California, for example, limits a home improvement down payment to 10% of the contract price or $1,000, whichever is less, under rules enforced by the Contractors State License Board (CSLB) (CSLB: Home Improvement Contracts guide). Other states cap deposits at roughly one-third of the contract price. Check your own state's limit before you agree to anything — our guide on How Much Deposit Should a Contractor Ask For? breaks down the general ranges.
Whatever the cap, the principle holds everywhere: you should never pay for materials or labor that haven't been delivered yet, and the rest of the payment schedule should track completed milestones (demo done, rough plumbing and electrical passed inspection, tile set, final walkthrough) rather than the calendar.
What Should Be in the Contract Before You Sign?
Get everything in writing: detailed scope, fixture and material specifics (not just "standard"), start and completion dates, the payment schedule, and who pulls permits. A realistic bathroom remodel timeline is one to several weeks depending on scope — see How Long Does a Bathroom Remodel Take? — and the contract should reflect that, with a defined process for change orders if something unexpected turns up once demo starts (it often does, especially behind old tile).
What to Do About It
- Pull the remodeler's license status yourself through your state board — don't rely on a number printed on a business card.
- Call the insurance agent listed on the certificate of insurance to confirm coverage is active.
- Call at least two recent references and ask specifically what went wrong on the job.
- Get three written bids on an identical scope before you decide, and ask any outlier bidder — high or low — to explain the gap.
- Confirm your state's deposit cap and don't pay beyond it, and structure remaining payments around finished milestones, not dates on a calendar.
