Have you always wanted a concrete sink? You can tell me the specs and color of you what in a sink or vessel and I will create it for you. Range of pricing depends on pounds and detail of final product. If you prefer a type of plumbing that you would like to be incorporated into final vessel, I ask that you please give an advanced notice. Most of my products are complete already and ready to be used. My products are sealed against water, oil and general moisture damage. All vessels and shower pans/bases can be bought in a rough concrete or can be dyed solid or designs can be created.
