15 Questions to Ask a Bathtub Refinisher Before You Book

By Tub Reglazing Directory Editorial Team · Updated 2026-09-02

Most people hire a tub refinisher the same way they hire anyone off a search results page: pick the one with decent reviews, compare a couple of prices, and book. That works often enough that no one talks about the times it doesn’t. But when a reglaze fails at six months, or when a contractor leaves your bathroom smelling of solvents for three days without warning you, or when the “lifetime warranty” turns out to be worth whatever a single-person LLC is worth, you wish you’d asked more before the job started.

These 15 questions are designed to separate contractors who know what they’re doing from those who don’t, and to protect you legally and financially if something goes wrong. They’re not gotcha questions. A good refinisher should be able to answer most of them without hesitation. Hesitation itself is useful data.

One terminology note before we get into it: reglazing, refinishing, and resurfacing all refer to the same process. It’s a spray-applied (or in some systems, pour-applied) topcoat that bonds to your existing tub. Neither term involves actual glass or factory enamel. Some contractors prefer one word over another; none of them signal a meaningfully different service.

Licensing and Insurance: What to Ask and How to Verify

1. Do you hold a contractor’s license, and can I verify it independently?

Licensing requirements for tub refinishers vary by state and sometimes by municipality. Some states have no specific category for refinishing at all. That doesn’t mean you skip the question; it means you need to know what applies where you live.

Ask the contractor directly, then verify yourself. California’s Contractors State License Board (CSLB), Florida’s Department of Business and Professional Regulation (DBPR), and Texas’s Department of Licensing and Regulation (TDLR) all have searchable online databases. Most other states have equivalent lookup tools. Don’t take a contractor’s word for their own licensing status. The search takes two minutes.

2. Do you carry general liability insurance and workers’ compensation, and will you send me proof from your insurer?

The BBB advises requesting certificates directly from the insurer rather than from the contractor. That matters because a certificate the contractor generates themselves can be outdated or faked. An active certificate of insurance from a real carrier protects you if a technician damages your bathroom or gets hurt on your property.

Workers’ comp is especially relevant here. Refinishing involves chemicals and confined spaces. If a technician is injured in your bathroom and the contractor carries no workers’ comp, you could be looking at a premises liability claim.

3. Are you EPA RRP-certified if my home was built before 1978?

This one catches a lot of people. Stripping or abrading an existing tub finish can disturb lead-based paint in older homes. Under the EPA’s Renovation, Repair and Painting Rule (40 CFR Part 745), contractors working in pre-1978 housing must be EPA-certified and must follow lead-safe work practices. Violations carry civil penalties per day per violation.

Ask to see the certification. If the contractor doesn’t know what RRP stands for, that’s your answer.

Coating System Questions: What They’re Actually Spraying

4. What brand of coating system do you use, and can I see the technical data sheet?

This is the question that separates knowledgeable contractors from people who learned to spray on YouTube. A professional should be able to name the product immediately: Napco, Multi-Tech, Rust-Oleum Specialty, Ekopel 2K, or another recognized system. They should also be able to pull up or email you the manufacturer’s technical data sheet (TDS).

The TDS tells you cure times, application conditions, required film thickness in mils, and compatible substrates. Napco’s TDS documents specify a 24-to-48-hour window before light water contact and up to 7 days for full chemical cure. If a contractor tells you the tub is ready to use in 12 hours and the TDS says otherwise, you know who to believe.

Ekopel 2K is worth understanding as a distinct system. It’s a two-component methyl methacrylate coating applied by pouring and spreading rather than spraying, and its ventilation and safety profile differs from spray-applied urethane systems. If your contractor uses it, the coating questions still apply, but some of the respirator and exhaust questions below will have different answers.

5. How many coats do you apply, and do you use a separate primer?

A single-coat finish is almost always a budget shortcut that shows within a year or two. Most quality systems call for a bonding primer followed by two or more topcoat passes. Some products, including Ekopel 2K, are designed to be applied in a single self-leveling coat without a separate primer, but only on properly prepared substrates. The point isn’t a magic number of coats; it’s whether the contractor knows their product’s specification and is following it.

6. How do you prepare the surface, and what do you do if you find previous coatings?

Surface prep is where most reglaze jobs succeed or fail. Ask specifically: do they chemical-etch the surface, mechanically abrade it, or both? What happens if they discover a prior reglaze when they start stripping?

Some contractors will refinish over an existing coating without disclosure. That’s a problem. Adhesion to a previous topcoat is worse than adhesion to the original substrate, and a contractor who layers coatings without telling you is setting you up for peeling. If stripping a prior coating is needed and they use a methylene chloride-based stripper, OSHA 29 CFR 1910.1052 sets a permissible exposure limit of 25 ppm as an 8-hour time-weighted average. Ask whether they use methylene chloride and what controls they have in place if so.

Ventilation and Safety: Protecting Your Household

7. What respirator does your technician wear, and are they fit-tested?

This is the most important safety question on the list, and most homeowners never ask it.

Two-part urethane topcoats, which are common in professional reglazing, contain isocyanates as a crosslinking agent. The EPA classifies isocyanates as a leading cause of occupational asthma. Some contractors use a half-face air-purifying respirator with organic vapor cartridges and consider that adequate. NIOSH Publication 96-111 says otherwise: for isocyanate spray operations, a supplied-air respirator is required, not a cartridge APR. Isocyanate cartridges don’t provide adequate warning properties before breakthrough.

OSHA 29 CFR 1910.134 requires that workers using respirators in hazardous atmospheres be medically evaluated and fit-tested before use. Ask if the technician has been through that process. A contractor who’s never heard of fit-testing is telling you something.

8. How do you ventilate the space, and where does the exhaust go?

Natural ventilation through an open window does not cut it. OSHA guidance (OSHA 3371) is explicit that spray coating in confined bathroom spaces requires exhaust ducted to the exterior. HVAC vents should be sealed during application to prevent solvent-laden air from circulating through the rest of the house.

Ask specifically: do they bring a temporary exhaust fan? Where does the duct exit? Do they seal HVAC registers? A contractor who relies on cracking a window is cutting a corner that affects your family’s air quality.

9. When is it safe for my family to re-enter the house, and who makes that call?

Get a specific answer, not “a few hours.” The EPA recommends that areas where isocyanate coatings are applied be vacated and ventilated thoroughly before re-entry, with adequate air exchange confirmed before occupants return. A responsible contractor will give you a specific re-entry window. Usually that’s a minimum of several hours after the exhaust fans have been running, with longer guidance for households with children, elderly members, or anyone with respiratory conditions.

If a contractor shrugs at this question, that tells you how much thought they’ve given to it.

Experience and Substrate Questions

10. How many tubs of my material type have you done?

Cast iron, steel, acrylic, and fiberglass are not the same substrate. They respond differently to surface preparation and bond differently to topcoats. An experienced contractor who does primarily acrylic tubs may not have significant experience with cast iron, where the prep process is more involved. Ask by name. “How many cast iron tubs have you refinished?” is a better question than “Are you experienced?”

If you’re comparing quotes from professional refinishers in Brooklyn in New York, this is the question that will most quickly separate the specialists from the generalists.

Warranty Questions: Get It in Writing

11. What does your warranty cover, for how long, and what voids it?

Verbal warranties are not warranties. Under the principles of the Magnuson-Moss Warranty Act, a written warranty should clearly state what is covered, the duration of coverage, the remedy provisions, and any conditions that void coverage. You’re entitled to review this document before you agree to the job.

Common warranty lengths run from 1 year to “lifetime.” Be skeptical of lifetime claims from small operators. A lifetime warranty is only as durable as the business behind it. Ask directly: what happens to this warranty if your company closes or you retire?

Also ask what voids the warranty. Most coatings are voided by abrasive cleaners, suction-cup bath accessories used before full cure, or unauthorized repairs. Those are reasonable conditions. But if the voiding conditions are so broad that a normal bathroom cleaning could trigger them, the warranty is nearly worthless in practice.

12. Is the warranty transferable if I sell the house?

A transferable warranty adds measurable value to a home sale. Not all contractors offer this. Worth asking, and worth getting the answer in writing.

Timeline and Cure Questions

13. What’s the cure schedule, and when can I use harsh cleaners or bath mats?

A tub that feels dry to the touch after a few hours has not cured. Polyurethane and urethane-based coatings typically need 5 to 7 days for full solvent off-gassing and chemical cross-linking. Using abrasive cleaners or placing suction-cup bath mats on the surface before full cure is one of the most common causes of premature peeling.

Ask the contractor to give you the cure schedule from the product’s TDS, not from memory. That’s a fair ask, and it tells you whether they’ve actually read the spec sheet for what they’re applying.

14. Do you do a final inspection before you leave, and what’s your touch-up policy if I notice a defect within the first week?

Minor runs, thin spots, or missed areas sometimes aren’t visible until the coating has cured and you’re looking at it under normal lighting. A contractor with confidence in their work will have a clear policy for coming back. Ask what that process looks like and get it in writing as part of the contract.

Payment and Contract Questions

15. What does the written contract include, and how much is the deposit?

The BBB recommends that home improvement deposits not exceed one-third of the total job cost. Full payment upfront before work begins is a meaningful red flag. The written contract should specify the coating system and brand being used, the scope of work, the timeline, the cure schedule, payment stages, warranty terms, and what happens if the job runs longer or additional prep work is discovered.

Change orders are where costs creep. If the contractor finds a prior coating that needs stripping, or significant surface damage, does the price change? What’s the process for authorizing additional charges? Get that in the contract before anyone picks up a spray gun.

One More Thing Before You Book

If you want a verifiable baseline for contractor quality, ask whether the contractor is a member of the Professional Refinishers Group (PRG). PRG is the primary U.S. Trade association for the refinishing industry. Membership isn’t a government license, but their code of practice requires written contracts, warranty disclosure, and proper ventilation practices. It’s a verifiable credential that indicates a contractor has at least committed to a professional standard.

PRG membership doesn’t guarantee a good job. But a contractor who’s never heard of PRG, can’t explain their coating system, won’t show you their insurance certificate, and offers only a verbal warranty has answered most of your 15 questions by default.

When you’re comparing quotes from professional tub refinishers in your state, bring this list. The ones who answer well will stand out fast. The ones who don’t will also stand out quickly. Book accordingly.

Frequently Asked Questions

Are reglazing and refinishing the same thing?

Yes. The terms are used interchangeably in the industry. Both refer to the same spray-applied topcoat process. Neither involves actual glass or factory enamel restoration. You may also hear bathtub resurfacing; that’s the same thing too.

How long after reglazing can I use my bathtub?

Most contractors allow light water contact after 24 to 48 hours, but full chemical cure typically takes 5 to 7 days depending on the coating system. Using harsh cleaners, suction-cup bath mats, or sitting standing water in the tub before full cure is a leading cause of premature peeling. Ask your contractor for the specific cure schedule from the product’s technical data sheet.

What type of respirator should a tub refinisher be wearing?

For spray-applied urethane systems containing isocyanates, NIOSH Publication 96-111 recommends a supplied-air respirator, not a half-face air-purifying respirator with organic vapor cartridges. If a contractor tells you their cartridge respirator is adequate for isocyanate spray work, that is a red flag.

Should I leave the house during a tub refinishing job?

Yes, and you should stay out until the contractor confirms the space has been adequately aired out. The EPA classifies isocyanates as a leading cause of occupational asthma. Children, elderly occupants, and anyone with respiratory conditions should be especially careful about re-entry timing. Get a specific re-entry window from your contractor before the job begins.

What does a legitimate written warranty for tub refinishing include?

Under Magnuson-Moss Warranty Act principles, a written warranty should clearly state what is covered, the duration, what the contractor will do to fix problems, and what voids the coverage. Lifetime warranties from small operators deserve extra scrutiny. Ask directly what happens to the warranty if the business closes.

Is a deposit normal for bathtub refinishing?

A deposit is normal, but the BBB recommends that home improvement deposits not exceed one-third of the total job cost. Be cautious about any contractor who asks for full payment upfront before starting work.

Do I need to ask about lead paint if my home is older?

If your home was built before 1978, yes. Stripping or abrading the existing tub finish can disturb lead-based paint, which triggers EPA RRP Rule requirements. Contractors working in pre-1978 housing must be certified under 40 CFR Part 745 and follow lead-safe work practices. Ask to see their EPA RRP certification before booking.
