Custom porcelain slab sinks, made by hand in Miami

A catalogue vanity stops the veining at the edge of the counter. A porcelain slab sink does not. We fabricate basins by hand from the same slab as the walls and floor, so the stone pattern runs straight through the room without interruption.

What it is

Porcelain slab, also called sintered stone, is the large-format material used for the wall and floor surfaces in high-end bathrooms. Rather than buying a separate basin, we cut one from the same slab, miter the edges so no raw edge shows, and finish it by hand.

Why it looks different

Two reasons. Book-matching means the veining continues across the join instead of restarting, so the eye reads the wall, counter and basin as one piece of stone. And mitered edges hide the material thickness, so a counter reads as a solid slab rather than a laminated panel.

Made to your dimensions

Because we fabricate rather than order, the size, depth, and drain position are decisions rather than constraints. Narrow bathrooms in particular benefit: a basin can be made shallow enough to keep the walkway clear, which no stock vanity will do.

Practical notes

• Porcelain is harder and less porous than natural marble, so it stains far less
• Wall-mounted installations need blocking planned during the framing stage, not after
• The tap can be wall-mounted or deck-mounted, decided before rough plumbing

How a slab basin is made

The slab is cut to the basin dimensions, the edges are mitered to 45 degrees so the two faces meet without showing material thickness, and the joints are bonded and worked by hand until the seam disappears. The drain opening is cut to suit the waste you have chosen. It is slow work, and it is the reason the finished piece reads as solid stone rather than as panels assembled into a box.

Care and durability

Porcelain slab is fired, dense and effectively non-porous, so it resists staining far better than natural marble and does not need sealing. Ordinary soap and water is enough. Avoid abrasive pads, which will dull any polished surface over time, and use a mat under anything heavy and sharp.

This is finish work that depends on decisions made early in the build, which is why we plan it as part of the whole bathroom rather than as an add-on. The same fabrication does not stop at the bathroom door: cooktop walls, countertops and feature walls are cut from the same slabs, in the same shop. See examples of our slab work, or ask in the chat.
