What Is a River Table? A Plain-English Guide
A river table is a piece of furniture built from one or more live-edge wood slabs — boards that keep the natural outer contour of the tree — arranged so the organic edges face each other. The gap between them is filled with clear or tinted epoxy resin, creating a "river" running through the wood.
How a river table is made
- Slab selection and drying. Slabs must be dried to a stable moisture content before work starts, or they can move and crack later.
- Flattening and prep. Slabs are flattened, bark is usually removed, and voids are stabilized.
- Forming and pouring. The slabs are set in a sealed mold and deep-pour epoxy is cast in one or more layers, often tinted to suggest water.
- Curing, flattening, finishing. After curing, the whole top is flattened, sanded through fine grits, and finished with oil, hardwax, or a polymer coat.
- Base. Tops are mounted on steel, wood, or combination bases.
Common woods
Walnut, maple, and oak are common on the mainland. In Hawaiʻi, koa, monkeypod, and mango are prized for figure and color.
What goes into each table
- Slab species, size, and figure
- Volume of resin (deep pours are expensive)
- Labor hours for flattening and finishing
- Base design and any integrated features — such as a working waterfall
Questions to ask a maker
- What moisture content were the slabs dried to?
- Which epoxy is used and is it rated for deep pours?
- What finish is applied and how should it be maintained?
