What are the best materials for a steam shower floor?

When installing a steam shower floor, you have a number of different materials from which to choose. What's most important is that the floor be completely leak-proof and, together with the walls, door and ceiling of the shower, be entirely sealed. Your level of experience and familiarity with certain materials may influence which direction you go.

Your basic choices include the following:

  • Prefabricated shower pan/base made of vinyl, acrylic or fiberglass
  • Cement
  • Ceramic tile

Shower pans are the easiest to install but feature the lowest aesthetic value. Cement and ceramic tile require more complex installations that require a special vapor barrier and perfect sealing, but they, especially tile, are the most attractive.
