A full bathroom renovation is a significant investment and a complex project, requiring expertise in everything from plumbing and electrical work to tile setting and cabinetry. A good general contractor acts as the project manager, coordinating all the tradespeople and ensuring the work is completed on time, on budget, and to a high standard. Choosing the right one is the most critical step in a successful renovation.
1. Define Your Project and Budget
Before you start your search, you need a clear vision for your new bathroom.
- Create a detailed plan: Decide on your “must-haves” and “nice-to-haves.” Will you be moving walls, relocating the toilet, or changing the shower’s footprint? These decisions will directly impact the cost and complexity of the project.
- Establish a realistic budget: Research the average cost of a bathroom renovation in your area. A general contractor’s fee is typically 10% to 20% of the total project cost. Having a clear budget helps you communicate your expectations and ensures you and the contractor are on the same page.
2. Gather Referrals and Research
Don’t rely on a single source. The best contractors often come from personal recommendations and thorough online research.
- Ask for word-of-mouth referrals: Talk to friends, family, and colleagues who have recently renovated their bathrooms. Ask them about their experience, the contractor’s communication, and whether they stayed on budget and schedule.
- Check online resources: Use reputable sites like the Better Business Bureau (BBB), Houzz, and Google Reviews to find contractors and read client testimonials. Pay attention to how the contractor responds to both positive and negative feedback. Look for contractors who specialize in bathroom or kitchen and bath renovations, as they will have the most relevant expertise.
3. Vet and Interview Potential Contractors
Once you have a list of 3-5 candidates, it’s time to pre-screen them with a phone call and an in-person meeting.
During the initial call, ask about:
- Their availability and typical project timeline.
- Their specific experience with full bathroom remodels.
- Their licensing and insurance status. (This is a non-negotiable must-have.)
During the in-person meeting, pay attention to their professionalism and communication style. This person will be in your home for an extended period, so you need to feel comfortable with them.
- Request Credentials: Ask to see their license number and proof of liability insurance and worker’s compensation. In the U.S., these are required by law and protect you from liability if an accident occurs on your property.
- Ask for References: Request a list of at least three recent clients with projects similar to yours. Don’t just get the names—call them. Ask about the contractor’s reliability, problem-solving skills, and whether the project was completed to their satisfaction.
- Review Their Portfolio: Look at photos of their past work, paying close attention to the details of the tile work, plumbing fixtures, and cabinetry. This gives you a sense of their craftsmanship and design aesthetic.
4. Get a Detailed, Written Proposal
Once you have a top candidate, request a comprehensive bid. A well-written contract is your best protection throughout the project.
A good contract should include:
- Detailed Scope of Work: A line-by-line breakdown of everything that will be done, from demolition to final paint. This should include what is not included to avoid misunderstandings.
- Materials and Specifications: The contract must specify the exact materials, brands, and models to be used, from the tile to the toilet.
- Total Cost and Payment Schedule: The total price should be clearly stated. The payment schedule should be tied to project milestones (e.g., 10% upfront, 30% upon demolition, 30% upon plumbing and electrical rough-in, etc.). Never pay the full amount upfront.
- Project Timeline: A clear start and end date, along with a schedule for key milestones.
- Change Order Process: This is crucial. It should detail how any changes to the original plan will be documented, priced, and approved in writing by both parties.
- Warranty Information: The contract should state what kind of warranty the contractor offers on their labor and the materials.
By taking the time to thoroughly vet your options, you can choose a reliable professional who will make your bathroom renovation a smooth and successful experience.
