I'm making the assumption that if I'm ok at woodworking I can make a mold for a sink basin to pour with concrete to go along a custom bathroom vanity. I've seen tutorials for bare concrete, terrazzo, smoother concrete, etc. but I would like to know if there is a way to make concrete look like travertine. I assume it'll be mixing white cement and sand, separate in batches and color each in different shades and pour them in sequence and carefully not to disturb the layers, maybe pouring on top of a spatula on top of the mold instead of directly over. Are there any options I should look into? or can I start with just this general information? I haven't designed the piece yet, but it would be 80cm wide, around 40cm deep, and between 10-30cm thick depending on the design of the basin.

Maybe I could add salt on the exterior to create the porous look of real travetine, but the part that touches water should be smooth, maybe I could fill the gaps with golden resin to go full luxury, but that would be another area I would have no experience in. I've seen videos of professionally made ones and I can see some reinforcement in the cement, I think it's glass fiber.

I would tackle that when possible

Maybe move the dining area under that, if possible get a chandelier that justifies that much length

You also need more sources of light
You can keep the walls bare, but one tall decorative feature will help a lot
