Shower Bases

When designing a new shower, start from the floor and work up. Coni-marble manufacturing makes standard-size and custom-size shower bases out of the Coni-marble material.

Standard bases are available in 11 sizes. They all have an attached threshold sill and a fixed location for a round drain.

With a custom base, you decide the shape, the size (up to 58.5” x 94”), and the location of the drain (within parameters). The threshold is a separate piece, so you can add one if you want, or have no threshold if that is your preference. The standard drain opening is round however there is an option of upgrading to a square or trough drain.

All shower bases are made to order and available in any of our Coni-marble colors.

You can scan, email, fax or drop off your plans to our Thorndale Showroom.

Depending on the product, your quote may include template and installation, or supply material only.


When you confirm your order, a down payment of 50% will allow us to order or manufacture your product. All
products are made to order and customized to your dimensions, and therefore, no refunds are issued. For kitchens
