Top Venetian Plaster Finishes for Bathrooms & Wet Areas

Tiles aren’t the only route to a beautiful bathroom anymore. Venetian plaster—our family of lime-based decorative finishes—creates seamless, spa-like surfaces that feel luxurious and perform well in humid spaces. When applied and sealed correctly, these finishes resist moisture and everyday splashes, with no grout lines to attract mould, and a natural depth you can’t achieve with paint or tile.

Whether you’re refreshing a small cloakroom or designing a statement wet room, Venetian plaster offers finishes ranging from silky polished walls to modern microcement for floors and high-use zones. In this guide, we’ll show you the best Venetian plaster finishes for bathrooms, plus what to consider for sealing and upkeep—so you can choose confidently and get results that last.

Why Venetian Plaster Works in Bathrooms

Bathrooms demand finishes that can handle humidity, splashes, and daily use without losing their beauty. Venetian plaster stands out because it combines timeless aesthetics with practical performance when applied and sealed correctly.

• Moisture Resistance – when sealed, Venetian plaster repels water and protects against steam or splashes.

• Seamless Surfaces – no grout lines where mould or mildew can build up.

• Durability – with correct preparation and finishing, Venetian plaster can last for decades.

• Luxury Appeal – from polished marble-like walls to soft matte textures, plaster elevates any bathroom.

Top Finishes for Bathrooms & Wet Areas

When choosing Venetian plaster for bathrooms, the right product system makes all the difference.

1. Marmorino Medium (Volare)

   • Lime-based plaster that can range from satin to polished.

   • Perfect for bathroom walls in humid conditions.

   • Works beautifully behind freestanding baths, above basins, or as feature walls.

   • Not suitable for showers or constant splash zones.

2. Microcement (Base + Finish system)

   • Modern, fully waterproof decorative coating.

   • Seamless and durable for floors, shower trays, wet walls, and countertops.

   • Best choice for heavy-use or high-splash areas.

3. Metallic & Pearl Effects (applied over Marmorino or Microcement base)

   • Decorative overlays in gold, silver, bronze, or pearl.

   • Great for statement powder rooms or spa bathrooms.

   • Use as accents, not as the main surface in wet areas.

Design Inspiration: Where to Use It

Venetian plaster and microcement open up far more design possibilities than tiles or paint. Popular applications include:

• Feature Walls Behind Baths – polished Marmorino (Volare) makes a spa-style focal point.

• Sink Splashbacks – seamless and easy to wipe down.

• Full Walls in Humid Zones – Marmorino for depth, Microcement for splash resistance.

• Shower Enclosures & Wet Rooms – Microcement is ideal here.

• Floors & Countertops – Microcement creates a modern, continuous finish.

• Ceilings – lime plaster overhead softens lighting and creates atmosphere.

Practical Considerations

• Sealing & Protection

  • Always use a protective sealer (e.g., Rain Protex for Marmorino, polyurethane topcoat for Microcement).

  • Correct sealing is what makes the finish last in humid environments.

• Maintenance

  • Clean with mild, non-abrasive products.

  • Avoid harsh chemicals which can damage sealers.

• Professional vs. DIY

  • Marmorino can be DIY with training, but wet-area Microcement is best left to trained applicators.
