Micalline cultured marble is a non-porous, durable blend of crushed stone and resin, protected by a gel coat. To keep it looking its best, use non-abrasive, pH-neutral cleaners like mild soaps or foaming bathroom sprays. Never use scouring powders, steel wool, or undiluted bleach, as these can scratch and dull the surface.
Understanding Your Cultured Marble
Cultured marble is man-made and waterproof—perfect for showers and baths. Cast in molds, its seamless look makes cleaning easier than natural stone. Owning a Micalline cultured marble shower brings even more durability and elegance.
Our “No Leak” systems offer peace of mind, but proper care is key to enjoying that shine for years.

Best Practices for Cleaning
What to Do:
- Use a squeegee or soft towel: After bathing, wipe down walls and pan to prevent spots and soap scum buildup.
- Clean with soft sponges or microfiber: Avoid anything abrasive to maintain the glossy finish.
- Check the silicone seals: Look for cracks or mold. Reseal as needed to keep everything watertight.
What to Avoid:
- Abrasive powders/cleaners: Products like Comet and Ajax will scratch and dull the surface.
- Harsh chemicals: Avoid undiluted bleach, harsh peroxide, paint strippers, or anything containing lye (like Drano). Rinse any accidental spills right away.
- Rough cleaning tools: Skip steel wool, wire sponges, or stiff brushes.
Dealing with Stains & Restoring Shine
Even with care, hard water and minor scratches can occur.
Removing Hard Water Stains:
Mix water, white vinegar, and baking soda. Spray, let sit for up to 30 minutes, then wipe and rinse. Don’t let it dry on the surface.
Restoring Shine:
Use high-quality automotive paste wax or Gel-Gloss. Apply and buff following label instructions. This restores gloss and makes future cleaning easier.
