Autumn Bathtub from Pietra Bianca. For any bathroom redesign or new development, our marble products will last for decades. A dense material that is non-porous, our terrazzo baths combine striking marble with a epoxy resin composite. Resistant to cracks and breakage, the tub remains undamaged by high temperatures and corrosion. Its unique antibacterial formula deters stains, retains heat and is resistant to yellowing, for a top-quality design that will last for years to come.
