These terrazzo shower bases from Crane look like the real deal. The website says that they truly are marble chips embedded in concrete, then polished to a high gloss. I have shower bases in two of my three bathrooms, and when I renovated about 5 years ago, I went with simple white Swanstone solid surface. While the Swanstone has worked out fine, I definitely would have checked out these Crane bases, if I’d known about them. Terrazzo is a most noble, retro material! These bases come in several colors (hint: go neutral) and sizes (hint: go minimum 36″x42″). Here’s the link to the Crane page.
Hey, if you have a Swanstone or fiberglass base, the only thing I can get to really keep it clean it Lysol Basin Tub & Tile Cleaner. The liquid spray is best – my husband actually orders it online. Using this cleaner, I really can keep the white base looking like new – although it may take several soaking applications. Suzie Homemaker (a real joke, you can bet), over and out.
