How to Choose a Contractor for a Senior Bathroom Remodel
A general bathroom remodeler can install a nice-looking shower. That's not the same skill as designing one that accounts for fall risk, mobility changes, and the specific building-code requirements around clearances and grab-bar placement. Choosing a contractor for a senior or accessible bathroom remodel means checking for a few specific things a standard remodeling company simply isn't trained to think about, on top of the usual licensing and insurance basics.
Here's exactly what to look for, in order of how much it actually matters.
1. Check for a CAPS Certification, and Know What It Actually Means
CAPS stands for Certified Aging-in-Place Specialist, a credential issued by the National Association of Home Builders. It's earned through actual coursework, not a badge a company can simply buy or add to a website. The training covers four areas: universal design principles, fall-risk reduction, the technical and building-code knowledge specific to accessible design, and how to talk with a homeowner or family about needs today versus needs five or ten years from now.
This matters because it's the difference between a contractor who can install a shower and one who's actually trained to design around how falls happen in a bathroom, where grab-bar blocking needs to go based on how someone actually moves through the space, and how ADA and building-code clearances apply to a real home rather than a generic diagram. Don't just take "we're certified" at face value. Ask which credential specifically, who issued it, and ask to see it.
2. Ask How They Handle Waterproofing, Not Just the Finish Material
Almost every contractor will happily talk about tile versus wall panels. Far fewer will give you a clear, specific answer about what's happening behind the walls. A curbless or low-threshold shower depends entirely on a properly engineered waterproofing system and floor slope, not the curb, to keep water contained. If a contractor can't explain their waterproofing approach in plain terms, or brushes past the question to get back to talking about finishes, that's worth noting.
A good sign here: a contractor who can talk knowledgeably about different waterproofing systems and why they use the one they do, not just the one their supplier happens to carry.
3. Confirm Whether Curbless or Low-Threshold Entry Is Standard or an Upsell
Ask directly: is a curbless or low-threshold entry included in the base price, or is it an add-on? Some companies quote a basic walk-in shower with a small step as the default and treat true zero-threshold entry as a premium feature. If accessibility is the entire reason you're doing this project, that distinction changes what you're actually comparing when you get quotes from different companies. Get the answer in writing, not just verbally during the sales visit.
4. Verify Licensing, Insurance, and How Permits Are Handled
This applies to any contractor, not just accessibility specialists, but it matters more here because these projects often involve plumbing changes and structural work behind the walls. Confirm the company carries general liability insurance and workers' compensation coverage, and ask directly whether your specific project requires a permit in your city or county. A contractor who says permits are "never needed, no matter what" is a red flag. Requirements genuinely vary by scope and jurisdiction, and a company that knows the difference is a company that's done this enough times to know the local rules.
5. Ask Who's Actually Doing the Installation
Some companies manage every step with their own crew, from demo through final walkthrough. Others sell the project, then hand it off to separate subcontractors for plumbing, tile, and finish work, each on their own schedule. Neither approach is automatically wrong, but it changes what timeline and accountability actually look like. If something goes wrong during the plumbing phase, is that the same company standing behind the tile work too? Ask for a specific, realistic timeline, and ask directly whether one crew handles the whole project or whether it's split across multiple trades.
6. Read the Warranty Carefully, Materials and Workmanship Are Not the Same Thing
A lot of warranties only cover materials, meaning if a wall panel is defective, it's covered, but if it was installed incorrectly, it isn't. Ask specifically whether the warranty covers workmanship as well as materials, and get the actual length and terms in writing rather than relying on a verbal "lifetime warranty" mentioned during the sales pitch.
7. Ask for References From Similar Accessibility Projects Specifically
A general portfolio of nice bathroom remodels doesn't tell you much about whether a company understands accessibility design specifically. Ask to see examples of curbless or barrier-free showers they've actually built, and if possible, ask to speak with a past customer who had a similar project, not just any past customer.
8. Ask Whether They Work With Occupational Therapists or Aging-in-Place Professionals
Contractors who specialize in this kind of work often have referral relationships with occupational therapists, physical therapists, or other professionals who assess mobility and home safety for a living. That's a meaningful signal. It means other professionals in the aging-in-place space trust this company enough to send clients their way, which is a harder thing to fake than a testimonial on a website.
Red Flags Worth Walking Away From
- Pressure to sign the same day for a "today only" discount
- Vague or evasive answers about waterproofing or how curbless entry is priced
- No willingness to put warranty terms in writing
- Inability to clearly explain what their certification actually covers
- No direct answer about who is physically doing the installation
A Quick Checklist to Bring to Your Consultation
- What specific credential do you hold, and can I see it?
- Walk me through your waterproofing system
- Is curbless or low-threshold entry standard, or an upgrade?
- Is your team licensed and insured, and will you handle permits if needed?
- Does your crew complete the whole project, or is it subcontracted out?
- Does your warranty cover workmanship, not just materials?
- Can I see examples or talk to references from similar accessibility projects?
Frequently Asked Questions
What does CAPS certification actually mean? CAPS stands for Certified Aging-in-Place Specialist, a credential issued by the National Association of Home Builders and earned through coursework covering universal design, fall-risk reduction, building codes for accessible design, and working with clients on evolving mobility needs.
Is a CAPS certification required to do this kind of work legally? No, it's not a legal requirement in most places, but it indicates specific training in accessibility design that a general contractor may not have.
Should I get multiple quotes before choosing a contractor? Yes, and when comparing them, confirm each quote covers the same scope, particularly whether curbless entry, waterproofing quality, and warranty terms are actually equivalent between bids, not just the bottom-line number.
What's the biggest mistake people make when hiring for this type of remodel? Comparing quotes purely on price without confirming they cover the same scope. A lower bid that treats curbless entry as an upsell or uses a thinner warranty isn't actually the same project as a higher bid that includes both standard.
Does it matter if the same company handles design and installation? It generally leads to more accountability. When one company manages the whole process, there's a single point of responsibility if an issue comes up, rather than different parties pointing to each other.
