River table cost: epoxy volume, materials and labor
Epoxy river tables are two expensive things combined: live-edge slabs and a lot of casting resin. They also take more steps than a solid wood table. If you're thinking about commissioning one, here's where the money goes and how to estimate the biggest variable yourself.
Where the cost comes from
The slabs. Live-edge slabs are sold individually, usually priced on the slab rather than strictly by board foot, and figured or wide slabs of walnut and other prized species cost the most. Bookmatched pairs, cut one after the other from the same log, are what give the river its mirrored edges.
The epoxy. Deep-pour casting resin is sold by the gallon, and a river table can need several gallons. The volume depends entirely on the size of the gap.
The mold and setup. The slabs sit in a sealed mold, usually melamine with tape or a release agent, leveled and clamped so the slabs don't float.
Pours and curing. Each product has a maximum pour depth per layer, because epoxy heats up as it cures. A thick river may need several pours, each with its own wait.
Flattening and finishing. After curing, the top is flattened (often with a router sled or CNC), sanded through many grits and finished. This is many hours of work.
Base and delivery. River tables are heavy. Ask about the base, and how the table will reach your home.
HomeAdvisor's custom furniture cost guide puts custom woodworking labor at $50 to $100 an hour plus materials, and with the steps above, labor adds up.
Estimate the epoxy yourself
Epoxy volume is length × average width × depth. In inches, divide by 231 to get US gallons. A river 72 inches long, averaging 8 inches wide and 1.75 inches deep holds 72 × 8 × 1.75 = 1,008 cubic inches, about 4.4 gallons, before any waste.
Our epoxy river table calculator does the conversion, adds a waste allowance and tells you how many pours your depth needs once you enter the maximum pour depth from the product's data sheet. Multiply the gallons to buy by the price of the resin you're considering and you have the resin line of the quote.
Ways to control the cost
- A narrower river. Volume scales directly with width, so a slimmer river uses less resin.
- A thinner top. Less depth means less resin and possibly fewer pours.
- Smaller or less figured slabs.
- A shorter table. Every inch of length is resin and slab.
- An inlay or resin-filled cracks instead of a full river, for the look at a fraction of the epoxy.
How to brief a river table
- Table size (length × width × height) and seating.
- River color: clear, tinted, opaque, metallic pigments. Send photos.
- Species, and whether you want bookmatched slabs.
- River shape: straight-ish, wide in the middle, branching.
- Base style.
- Finish on top of the epoxy: many makers apply a hard-wearing topcoat.
- Deadline, delivery address and access (stairs, doorways).
- Budget range.
