Installing custom sized shower pan on concrete slab
I am removing an existing fiberglass shower unit to replace it with a larger, custom-built ceramic tile shower. The subfloor is a post-tension concrete slab. I will not be able to move the drain, so it won't be centered in the new shower floor. I'm Ok with having an off-center drain. But, all the shower pans I'm finding put the drain hole right in the center. Are there custom shower pans I can purchase with offf-center drain holes, or can I create a custom pan using products available on the open market? If so, what products can you recommend I consider?
