Refinishing & Repairs
Cultured Marble Refinishing & Repairs
Cultured marble tubs, sinks, vanities, and showers are built to last — but the glossy gel coat that gives them their shine doesn't last forever.
Heat, hard water, and years of cleaning can leave cultured marble's gel coat yellowed, dull, cracked, or chipped. We bring cultured marble surfaces back to life: repairing thermal-shock cracks and chips, restoring a yellowed or dulled gel coat, and refinishing the whole piece to a smooth, factory-fresh shine — all without tearing out the fixture.
Cultured marble isn't like the acrylic or porcelain most refinishers work with every day, and plenty of companies turn the job down rather than risk it. It's one of the surfaces we specialize in, and one of the reasons homeowners across Calgary call us specifically for it.
- Thermal-shock cracks & chips repaired
- Yellowed gel coat restored
- Tubs, sinks, vanities & showers
- Specialists — not a job we turn away
Why Cultured Marble Is Different
Not Stone, Not Quartz — and Not Every Refinisher's Specialty
Cultured marble is a manufactured surface: crushed limestone or marble dust bound in a polyester resin, cast into a mold, and topped with a thin gel coat that gives it its shine. That makes it structurally different from natural stone, quartz, porcelain, and acrylic — the surfaces most refinishing companies build their whole process around.
The gel coat responds differently to stripping and etching than an acrylic tub does, and the thermal-shock cracks cultured marble is known for — hairline cracks from hot water hitting a cold surface, or vice versa — need a specific structural repair before any coating goes on. Skip that step, or use the wrong approach, and the repair fails within months, which is exactly why a lot of refinishers pass on cultured marble jobs rather than risk it.
It's a surface we've worked with for years, on tubs, integrated sink-and-vanity units, shower surrounds, and countertops across Calgary. If you've called around and been turned down, or had a "quick fix" fail on you before, that's usually why — and it's the gap we specialize in closing.
Structural Repair First
Thermal-shock cracks are repaired at the structural level before any coating goes on, not just filled and painted over.
Save vs. Replacement
Integrated sink-and-counter or tub-and-surround units are expensive to source as a matched replacement — refinishing costs a fraction.
Color & Pattern Matching
Cultured marble's mixed-in color and veining is matched carefully so a repair blends into the surrounding surface.
No Fixture Removed
Every job is done in place — no demolition, no re-plumbing, no waiting on a special-order replacement.
Recent Work
A Cultured Marble Tub & Surround, Refinished
This is an actual cultured marble tub-and-surround unit we refinished — the full gel coat resurfaced to a smooth, glossy, factory-fresh finish, with the fixture never leaving the bathroom.
Jobs like this are exactly why we specialize in cultured marble: the material's integrated construction means the tub, surround walls, and often a built-in soap shelf are all one continuous piece. Every seam and corner has to be worked by hand to match the rest of the surface, which is a big part of why the material takes real, specific experience to get right.

Our Process
How We Refinish Cultured Marble
Cultured marble gets a process built around what actually makes the material different — not the same steps we'd use on an acrylic tub or a porcelain sink.
Protect & Prep the Space
We mask off the surrounding floors, walls, and fixtures with plastic sheeting and tape so overspray and dust stay contained to the piece itself.
Assess & Structurally Repair Cracks
Thermal-shock cracks and chips are identified and structurally repaired first — filled and reinforced so the repair holds under the coating, not just cosmetically patched over.
Strip & Prep the Gel Coat
The existing gel coat is stripped and prepped with the specific process cultured marble needs, distinct from the prep an acrylic or porcelain surface gets.
Color & Pattern Match
The base color, and any veining or pattern in the surface, is matched so repaired areas blend into the surrounding gel coat.
Prime & Spray the Coating
We spray a bonding primer followed by multiple coats of a high-gloss finish engineered to bond with cultured marble's gel coat chemistry.
Cure, Reinstall & Walkthrough
Once the final coat is on and cured, any hardware or fittings are reinstalled. We walk the finished piece with you and confirm exactly when it's safe to use.
What We Refinish
Every Cultured Marble Fixture, Handled Right
From standalone pieces to fully integrated units, we work with cultured marble across the whole bathroom — and the kitchen, when it turns up there too.
Cultured Marble Tubs
Full tub shells refinished to a smooth, glossy factory finish, with structural crack repair where needed.
Integrated Sink & Vanity Tops
One-piece sink-and-counter units repaired and refinished as a single seamless surface.
Shower Surrounds
Walls, pan, and built-in shelving refinished together without regrouting or retiling.
Countertops
Bathroom and kitchen cultured marble counters refinished to remove yellowing, staining, and dullness.
Tub & Surround Combo Units
The full integrated piece — tub, walls, and soap shelf — refinished as one continuous surface.
Window Sills & Accessories
Smaller cultured marble accents refinished to match the rest of a refreshed bathroom.
Care & Maintenance
Keeping Refinished Cultured Marble Looking New
A little care goes a long way — especially since the way cultured marble is treated day to day is often what caused the original damage.
- Wait before use. Give the coating its full cure window — usually 24 to 48 hours — before running water.
- Skip abrasive cleaners. Scouring powders, steel wool, and harsh abrasive pads will dull a refinished surface over time. Stick to non-abrasive liquid cleaners and a soft cloth or sponge.
- Avoid extreme temperature swings. Don't pour boiling water directly onto a cold surface, or run cold water onto one that's just been in the heat — this is what causes thermal-shock cracking in the first place.
- Don't let water sit. Cultured marble's gel coat holds up better when standing water is wiped away rather than left on the surface for long periods.
- Avoid dropping heavy or sharp objects. The coating resists everyday wear well, but a dropped bottle or razor can still chip it, just like it could a factory finish.

FAQ
Cultured Marble Refinishing Questions
Cultured marble is a manufactured surface — crushed limestone or marble dust mixed into a polyester resin, cast into a mold, and finished with a thin gel coat for the shine. It's not natural stone and not quartz, and that difference is exactly why it needs a different repair and refinishing approach than either one.
Cultured marble's gel coat behaves differently than the acrylic and porcelain surfaces most refinishers work with every day, and the thermal-shock cracks it's prone to require a specific repair technique before any coating goes on. Get either step wrong and the fix fails fast, so a lot of refinishers avoid the material rather than risk a job that doesn't hold up. We've refinished cultured marble specifically for years and work with it regularly.
Yes, when they're repaired correctly. We fill and structurally repair the crack or chip first, then blend and refinish the surrounding gel coat so the repair doesn't show once the piece is recoated.
UV exposure, heat, and the natural aging of the gel coat resin all contribute to yellowing over time — it's a normal part of how the material ages, not a sign of a defect. Refinishing restores the original color.
Yes, usually by a significant margin, especially for integrated sink-and-counter or tub-and-surround units, which are expensive to source and install as a matched replacement.
Often, yes, if they're all part of the same job — we regularly refinish a full cultured marble bathroom, including the tub, surround, and vanity top, in a single visit.
Most single pieces are finished in a single visit. Jobs with significant crack repair need extra time for the repair to cure before coating.
Yes, every cultured marble job we complete is backed by a written warranty. We'll go over the specific coverage for your project as part of your quote.
