25 Questions to Ask a Bathroom Contractor Before Signing

Why the Right Questions Matter More Than the Lowest Bid

Every year, homeowners across the Sacramento area hire bathroom contractors based primarily on price. They collect three bids, choose the lowest one, sign the contract, and hope for the best. Six weeks later, many of them are dealing with missed deadlines, surprise costs, subpar workmanship, or a contractor who stopped returning phone calls.

The reason is simple: price tells you what you'll pay, but it tells you nothing about what you'll get. A $12,000 bid from a licensed, insured contractor with 15 years of bathroom-specific experience is a fundamentally different product than a $12,000 bid from a general handyman who "does bathrooms too." The only way to distinguish between them is by asking the right questions.

Over the years at Oakwood Remodeling Group, we've seen homeowners who asked excellent questions end up with excellent results — even when they didn't choose us. Informed homeowners make better decisions regardless of which contractor they select. That's why we created this comprehensive list of 25 questions organized into five categories that cover every critical aspect of the contractor selection process.

Print this list. Bring it to every consultation. Take notes on the answers. Then compare responses across contractors. The patterns will tell you everything you need to know.

Category 1: Credentials and Licensing (Questions 1–5)

These questions establish whether the contractor is legally authorized to perform bathroom remodeling work in California. Start here — if the answers are unsatisfactory, you don't need to ask the remaining 20 questions.

Category 2: Experience and Portfolio (Questions 6–10)

These questions assess whether the contractor has relevant, specific experience with bathroom remodeling — not just general construction.

Category 3: Project Management (Questions 11–15)

These questions reveal how the contractor runs their projects day-to-day — communication, scheduling, problem-solving, and accountability.

Category 4: Financial and Contractual (Questions 16–20)

These questions address the financial structure of the project — how you'll pay, what you'll pay for, and how changes are handled.

Category 5: Warranty and Aftercare (Questions 21–25)

These questions address what happens after the project is complete — arguably the most important long-term consideration.

Reading Between the Lines: Good vs. Bad Answers

The best contractors answer questions with specificity, confidence, and transparency. They name numbers, timelines, processes, and people. They volunteer information rather than waiting to be asked. And they welcome tough questions because they know their answers will withstand scrutiny.

Red flag answers share common traits: vagueness ("a few weeks," "we'll figure it out"), defensiveness ("nobody else asks that"), deflection ("you don't need to worry about that"), and promises without documentation ("I guarantee it" without a written warranty).

Pay attention to how the contractor responds to your questions, not just what they say. A contractor who is visibly annoyed by your due diligence is telling you something important about how they'll respond when you have concerns during the project. The consultation is an audition, and the questions are the script.

Absolute Deal Breakers

Regardless of price, portfolio, or personality, the following responses should end the conversation immediately:

• "You don't need a permit for this." Most bathroom remodels involving plumbing, electrical, or structural changes require permits. Skipping permits is illegal, voids warranties, and creates problems when you sell your home.
• "We don't usually do contracts." California law requires a written contract for any project exceeding $500. A contractor who avoids contracts is avoiding accountability.
• "I can give you a better price if you pay cash." This usually means they're not reporting income, which correlates with cutting other corners. It also eliminates your paper trail if a dispute arises.
• Inability or unwillingness to provide a license number. Full stop. No license means no legal authority to work, no bond, no CSLB oversight, and no recourse if something goes wrong.
• "We need 50% upfront." California law limits deposits to $1,000 or 10% of the contract, whichever is less. Demanding more is illegal.

These aren't judgment calls — they're non-negotiable standards that separate legitimate contractors from operators who put your money, property, and safety at risk.

How to Use This Checklist During Consultations

When meeting with contractors, print this list and bring it with you. Don't feel awkward about referring to it during the conversation — any professional contractor will respect your preparation. In fact, at Oakwood Remodeling Group, we appreciate it when prospective clients arrive with detailed questions. It tells us they're serious, informed, and the kind of client we love working with.

Take notes on each contractor's answers. After meeting with 3–5 contractors, compare their responses side by side. You'll quickly see who provided detailed, confident answers and who was vague or evasive. The pattern almost always aligns with the quality of work they deliver.

Remember: the cheapest bid is rarely the best value, and the most charismatic salesperson isn't necessarily the best contractor. Let the answers to these 25 questions guide your decision, and you'll dramatically increase your chances of a successful, stress-free bathroom remodel.
