What Questions Should I Ask a Bathroom Contractor?

If you’re planning a bathroom renovation, choosing the right contractor is one of the most important decisions you’ll make. For many homeowners—especially those planning to stay in their homes long term—a bathroom renovation isn’t just about updating finishes. It’s about improving comfort, safety, and functionality for years to come.


At Clay, many of our clients are homeowners who plan to age in place or stay in their homes well into retirement. They want a renovation done properly, safely, and to code—without surprises later.

Over the years, we’ve seen firsthand what happens when homeowners ask the right questions—and when they don’t. In fact, we’re currently working on a project where we’re repairing a bathroom renovation that was done incorrectly and not built to code by a contractor who is now out of business. Fixing those kinds of mistakes often requires engineers and significant reconstruction.

Before hiring a contractor, here are some important questions every homeowner should ask.

1. Are You Accredited or a Member of Professional Associations?


One of the biggest mistakes homeowners make is choosing a contractor based solely on price. Look for contractors who are part of recognized professional organizations. In London, Ontario, we recommend homeowners look for contractors who are members of:

• The London Home Builders’ Association (LHBA)
• RenoMark-certified contractors

These organizations require members to follow professional standards, ethical guidelines, and industry best practices. Membership is one way to confirm that a contractor is committed to quality and accountability.

2. Can I Speak With Previous Clients?


Reputable contractors should be happy to provide references. Many prospective clients prefer speaking directly with homeowners we’ve worked with before. It allows them to ask real questions about the experience, communication, and the finished renovation.


Questions you might ask references include:

• Was the project completed on schedule?
• How was communication throughout the renovation?
• Were there any unexpected issues, and how were they handled?
• Would you hire the contractor again?


Hearing directly from past clients can provide reassurance that you’re choosing the right team.

3. How Will Communication Work During the Project?

Bathroom renovations can take several weeks to months, and good communication is key to a smooth experience. Every homeowner has different preferences when it comes to staying informed. Some clients prefer:


• Weekly email updates
• Phone calls
• In-person meetings


A good contractor will discuss communication expectations before the project begins and adapt to your preferred style. Clear communication helps avoid misunderstandings, keeps projects on track, and ensures homeowners always know what’s happening next.

4. What Warranty and Post-Project Support Do You Offer?

A renovation should come with peace of mind. Ask contractors what type of warranty they provide and how they handle issues after the project is complete. A company that stands behind its work will have clear policies for addressing problems if they arise.

At Clay, we provide a 3-year workmanship warranty and remain available to support clients after their renovation is finished. Long-term relationships with clients are important to us, and many of our projects come from referrals and repeat customers.

5. Who Designs the Bathroom and Helps With Selections?


One of the most overwhelming parts of a bathroom renovation is choosing materials, fixtures, and finishes.

Some contractors expect homeowners to manage these decisions themselves, which can lead to delays and mismatched products. A design-build company simplifies the process. At Clay, we have two in-house designers, including a designer certified through the Adaptive Homes program and a NKBA-certified Kitchen & Bath designer. Our design team helps guide clients through selections—from tile and fixtures to cabinetry—ensuring everything works together both visually and functionally.

6. Do You Have Experience With Aging-in-Place Bathrooms?

Many homeowners today are planning renovations with the future in mind.

Features such as:
• Curbless showers
• Accessible layouts
• Grab bar support
• Wider clearances
• Improved lighting
can help make bathrooms safer and easier to use as mobility needs change.

Working with contractors trained in aging-in-place design ensures these features are integrated properly without sacrificing style.

7. How Do You Handle Custom Elements Like Cabinetry or Millwork?


Bathroom projects often involve custom solutions, especially in older homes.

At Clay, our millwork is built in-house, which allows us to adapt to project needs and timelines more easily. This flexibility helps us coordinate cabinetry installation with the construction schedule and maintain quality control.

It also allows us to design custom storage and vanity solutions that truly fit the space.

The Right Contractor Makes All the Difference


A bathroom renovation should improve your home—not create future problems.

Taking the time to ask the right questions can help you find a contractor who is experienced, transparent, and committed to quality work.
If you’re planning a bathroom renovation and want guidance on what’s possible for your space, working with an experienced design-build team can make the process much smoother.
