Bathtub Refinishing / Reglazing
Handis bathtub refinishing — sometimes called reglazing — applies a three-coat epoxy or polyurethane coating over a structurally sound porcelain-on-steel, cast-iron, fiberglass, or acrylic tub that has lost its original surface to scratching, yellowing, chalking, etching, or chipping — from $500 with a 24 to 48 hour cure and a 10 to 15 year service life. The 1962 cast-iron tub that is perfect underneath but the surface has gone yellow. The 1990s fiberglass that has chalked white and lost its shine. The porcelain tub the previous owner used Comet on for two decades and the bottom is scratched matte. Refinishing resets the surface for a fraction of replacement cost and zero plumbing work — but the result is a coating, not the original glaze, and aggressive cleaning will wear it through. Refinishing is the right call when the tub is structurally sound; refinishing on a cracked or compromised tub does not fix the structural problem and is not in our scope.
Service
What Does a Bathtub Refinishing or Reglazing Include?
Bathtub refinishing — sometimes called reglazing — is the surface coating service that applies a three-coat epoxy or polyurethane chemistry over a structurally sound existing tub. Handis covers refinishing from $500 on standard alcove tubs (5-foot porcelain-on-steel, cast iron, fiberglass, acrylic). The job runs 3 to 4 hours of work plus 24 to 48 hours of cure before the tub can be used. Cheaper than replacement, zero plumbing work, 10 to 15 year service life with non-abrasive cleaning. Honest expectation: it is a coating, not the original porcelain or enamel glaze.
Containment and Ventilation
Refinishing chemistry releases solvent fumes during application and cure. Before anything is sprayed or rolled, we tape plastic sheeting around the entire wet zone (tub apron, surround tile, floor) and run a ventilation fan in the doorway venting outdoors. The tech wears a respirator rated for organic vapors. Bathroom door stays closed during work. Other rooms of the house are unaffected.
Strip and Chemical Clean of the Existing Surface
Existing surface gets a full chemical strip with a methylene-chloride-free industrial cleaner (the older methylene-chloride strippers are now restricted under EPA TSCA Section 6(h) and we do not use them). Strip removes years of soap-scum buildup, body-oil residue, and any cleaning-product film. After strip, the surface gets a clean-water rinse and a final acetone wipe to remove any residue.
Mechanical Etch for Adhesion Bite
The new coating bonds to the substrate only on a properly-etched surface. We mechanically etch the cleaned surface with a fine-grit abrasive pad (180 grit on porcelain and cast iron; 220 grit on fiberglass and acrylic). The etch breaks the smooth original surface tension and gives the bonding agent something to bite into. Without proper etch the coating peels in sheets within months.
Small Chip Repair (Up to 1 Inch Diameter)
Chips in the original surface up to 1 inch diameter get filled with a two-part polyester body filler, sanded smooth, and feathered into the surrounding surface before the bonding agent coat. The filler bonds to the substrate, sands flat, and disappears under the three-coat refinish. Chips larger than 1 inch are a structural concern (the chip exposes raw steel or cast iron to corrosion, which compromises the tub long-term) and we recommend tub replacement instead of refinishing on those cases.
Three-Coat Epoxy or Polyurethane Chemistry
Two chemistry options. Two-part epoxy (lower cost, slightly shorter life at 10 to 12 years, harder to repair if damaged) is the budget standard. Two-part polyurethane (higher cost, longer life at 12 to 15 years, slightly more flexible and impact-resistant) is the upgrade. Both apply as three coats — bonding agent (the first coat that adheres to the etched substrate), base coat (the body of the coating), and top coat (the glossy surface). Each coat is sprayed or rolled to a uniform thickness with a 1-hour flash cure between coats.
24-48 Hour Cure Before Use
The full three-coat application reaches handle-cure (no fingerprint pickup) at about 8 hours, but the tub does not return to bath or shower use until the full chemical cross-link completes — 24 hours for epoxy in warm dry conditions, 48 hours for polyurethane or in Seattle winter humidity. We leave a printed cure-window note on the bathroom door, confirm verbally before leaving, and hand the homeowner a written care sheet that lists what cleaning products are safe (Bar Keepers Friend Liquid Soft Cleanser, Dawn dish soap, mild surface cleaners with a soft microfiber or nylon pad) and what is not (Comet, steel wool, abrasive scrub pads, bleach gels left on the surface for hours).
How a Bathtub Refinishing Works
Seven sequential steps from containment through the 24 to 48 hour cure window — the actual sequence we follow on every refinish.
Contain the Work Area and Set Up Ventilation
Plastic sheeting taped around the wet-zone (tub apron, surround tile, floor). Ventilation fan in the doorway venting outdoors. Tech wears a respirator rated for organic vapors. Bathroom door closed during work; other rooms unaffected.
Strip the Existing Surface
Methylene-chloride-free industrial stripper removes soap-scum buildup, body-oil residue, and cleaning-product film. Clean-water rinse, final acetone wipe. The strip is the foundation — a dirty surface ruins the adhesion no matter what coating goes on top.
Repair Chips Up to 1 Inch With Polyester Filler
Small chips filled with two-part polyester body filler, sanded smooth, feathered into the surrounding surface. Chips larger than 1 inch indicate structural concern (exposed raw steel or cast iron) and we recommend replacement instead of refinishing on those.
Mechanically Etch for Adhesion
180 grit abrasive pad on porcelain and cast iron; 220 grit on fiberglass and acrylic. The etch breaks the smooth surface tension and gives the bonding agent something to bite into. Without proper etch the coating peels in sheets within months.
Apply Bonding Agent — Coat One
First of three coats. Bonding agent (the chemistry-specific adhesion promoter) sprayed or rolled to a uniform thickness on the etched surface. 1 hour flash cure before the next coat.
Apply Base Coat and Top Coat — Coats Two and Three
Base coat (the body of the coating) sprayed to uniform thickness, 1 hour flash. Top coat (the glossy surface that meets water and use) sprayed last to a uniform thickness. Total three-coat thickness is about 8 to 12 mils.
Cure 24-48 Hours Before Regular Use
Handle-cure (no fingerprint pickup) at about 8 hours. Full chemical cross-link completes at 24 hours for epoxy in warm dry conditions, 48 hours for polyurethane or in Seattle winter humidity. Care sheet handed to the homeowner with the safe-cleaning product list.
Bathtub Refinishing Pricing
Final pricing depends on tub material, tub size, chemistry choice (epoxy is standard; polyurethane is the upgrade), color (white is standard; specialty colors run higher), and how much chip repair the substrate needs. Request a free estimate for an accurate quote.

Why Handis for Bathtub Refinishing
Refinishing is the right answer when the tub is structurally sound and the surface is the problem. A 50-year-old cast iron tub with a yellowed surface refinishes beautifully and gives you another 15 years on a tub that would cost $5,000 to remove and replace. A 25-year-old fiberglass that has chalked refinishes for $500 instead of $3,000 to swap. The wrong answer is refinishing a tub with structural problems — a hairline crack across the bottom, a chip larger than 1 inch that has exposed raw steel to corrosion, a fiberglass bottom that flexes under occupant weight. We assess structural condition first on the booking call and the first visit; refinishing goes ahead only when the underlying tub is sound. Otherwise we route to like-for-like replacement honestly.
Structural assessment first — honest refinish vs replace call
Refinishing works only on a structurally sound tub. Hairline cracks, chips larger than 1 inch (exposed raw steel or cast iron prone to corrosion), fiberglass bottoms that flex under weight, and tub flanges separated from the surround tile are all signs that the underlying tub is past refinishing — and a refinish on a compromised tub is a 6-month cover, not a fix. We assess structural condition on the booking call and the first visit and we route honestly. Like-for-like replacement is the right answer on a tub past refinishing.
Methylene-chloride-free strippers — modern chemistry only
EPA TSCA Section 6(h) restricted methylene chloride for consumer paint and coating removal in 2019 because of the cardiac and neurological hazards in poorly ventilated spaces. We use modern methylene-chloride-free industrial strippers on every refinish — slower than the old chemistry but safer for the tech, the homeowner, and the indoor air quality of the rest of the house during the 3 to 4 hour work window.
Ventilation and respirator — every refinish, every time
Refinishing chemistry off-gasses solvent fumes during application and cure. We run a ventilation fan in the bathroom doorway venting outdoors on every refinish, and the tech wears a respirator rated for organic vapors. The bathroom door stays closed. Other rooms of the house are unaffected by smell or air quality. The post-cure off-gassing is minimal once the chemistry has cross-linked, but we recommend leaving the bathroom window cracked open for the first 24 hours post-cure if conditions allow.
Mechanical etch — the step DIY kits skip
The bonding agent adheres to the substrate only on a properly-etched surface. We mechanically etch every tub with the grit-appropriate abrasive pad before any coating goes on. DIY refinishing kits skip this step (or recommend a chemical etch that does not bite as deeply) and that is why DIY refinishes peel in sheets within 6 to 12 months. The 10 to 15 year service life on a professional refinish is largely about the etch step being done correctly.
Care sheet — written, on the door, before we leave
The refinish lasts 10 to 15 years if the cleaning matches what the coating can take. Safe cleaners (Bar Keepers Friend Liquid Soft Cleanser, Dawn dish soap, mild surface cleaners with a soft microfiber or nylon pad) keep the surface looking new for the full life. Aggressive cleaners (Comet, Ajax, abrasive scrub pads, steel wool, bleach gels left on the surface for hours) wear through the coating in 3 to 5 years. We hand the homeowner a printed care sheet on completion and leave a copy on the bathroom door alongside the cure-window note.
1-year coating warranty + 30-day workmanship guarantee
30-day workmanship guarantee on the refinish install — if the coating shows visible adhesion failure (peeling, lifting at an edge, blistering) within 30 days, we strip and re-do at no charge. A 1-year coating warranty extends that to one full year — coating failure within 12 months of completion is covered at no charge as long as the care-sheet instructions have been followed. The warranty does not cover wear-through from non-recommended cleaners, impact damage (dropped objects, sharp scratches), or the coating returning to looking dull-but-intact at year 12 (normal end-of-life).
Estimate
Tell us the tub material (porcelain-on-steel, cast iron, fiberglass, acrylic), the rough age, the size (standard 5-foot alcove or larger), the current condition (scratched, yellowed, chalked, chipped — how many chips and how big), and the color you want (white standard; almond, bone, biscuit, beige, light gray, light blue available as upgrades). We tell you on the booking call whether refinishing is the right answer or whether the tub is past refinishing and like-for-like replacement is the honest call.
Customer Reviews
Bathtub refinishing reviews from real Handis customers.
1962 cast-iron tub in our Ballard Craftsman. Surface had gone yellow and chalky over decades. Handis assessed it as structurally sound (no cracks, no chip larger than 1 inch), recommended refinishing instead of replacement. Three-coat polyurethane upgrade, 48-hour cure. Tub looks like a brand-new white cast iron. Saved us probably $4,000 over replacement.
1985 fiberglass tub had chalked so badly the bottom was rough to the touch. Tech ventilated the bathroom, stripped, etched, three-coat epoxy in white. 24-hour cure, used the shower the next evening. Two years in, surface is still glossy and white. The written care sheet was the part I most appreciated — they were honest about what would and would not damage the coating.
Porcelain-on-steel tub in our hall bath — scratched bottom from years of Comet, no chips, structurally fine. Refinished in epoxy white, 24-hour cure. The before/after photo difference is dramatic. We are now using only Bar Keepers Friend Liquid as the tech recommended; the surface still looks new 18 months later.
We called Handis for a refinish on a 30-year-old fiberglass tub. The tech showed up, examined the bottom, and pointed out it was flexing under weight — refinishing would have been a 6-month cover at best. He recommended replacement instead, walked us through the like-for-like service, and rebooked us for that. Honest call saved us money and a re-do.
Walk-in tile shower pan that had gone yellow at the drain. Handis did a pan-only refinish with the slip-resistant texture in the bottom. $600 plus the texture add-on. Looks white and clean again, much safer on wet feet than the original tile pan was. 24-hour cure, used the next day.
