Design your resin table
Four quick taps. The sketch and the price change as you pick. When you send it, one Irish resin table maker gets your design and comes back to you with a price.

Drawing your table. This takes 20 to 50 seconds.
Your request is already through, so you can close this page if you need to.
That's an AI concept, not a drawing to build from. Every slab is different: the maker shows you the real boards before anything is cut.
We couldn't do this one. Some photos don't work: a clearer, wider shot in daylight usually does.
Your request is in: you'll still get a call with a price.
Key timber & casting resin terms explained
Deep-Pour (Casting) Epoxy Resin
A slow-curing, low-viscosity two-part epoxy formulated with a reduced exothermic reaction so it can be poured in single layers of 25 mm to 50 mm between timber slabs without overheating, yellowing, or cracking.
Exothermic Peak (Thermal Runaway)
The heat generated internally as liquid epoxy resin and hardener cross-link; if poured deeper than the resin's rated depth or in a room warmer than 22C, the pour can overheat above 80C, causing bubbles, amber discolouration, or shrinkage cracks.
Flood Coat (Table-Top Coating Epoxy)
A high-build, self-levelling 2 mm to 3 mm surface coat poured across the entire sanded wood-and-resin top, or replaced by a matte hardwax oil finish, depending on whether a mirror gloss or natural tactile timber feel is preferred.
HALS UV Stabilisers & Polyurethane Topcoats
Hindered amine light stabilisers blended into modern casting resins, often paired with a 2K matte or satin polyurethane topcoat, to slow ultraviolet yellowing in bright rooms.
Hardwax Oil vs 2K Polyurethane Finish
Hardwax oil buffs into the timber grain and polished resin for a warm, low-sheen, easily spot-repairable finish, whereas a sprayed two-pack polyurethane lacquer gives higher scratch and ring resistance on busy family dining tables.
Heat Deflection Temperature (40C to 60C)
The temperature range where cured casting epoxy begins to soften slightly under load, which is why hot pans, oven dishes, and freshly boiled mugs should always sit on coasters or trivets.
Kiln-Dried Timber Moisture Content (8% to 12%)
Drying thick 50 mm to 75 mm hardwood slabs in a dehumidification or vacuum kiln down to 8% to 12% internal moisture content so the wood will not warp, cup, or pull away from the cured epoxy in a centrally heated Irish home.
Live Edge (Waney Edge) Hardwood Slab
A through-and-through sawn plank cut along the length of a tree trunk that keeps the natural contoured outer edge beneath the bark, forming the organic river banks down the centre of a river table.
Mica Metallic Pigments & Alcohol Tints
Mineral mica powders that create swirling pearlescent ocean, emerald, copper, or charcoal patterns in a river channel, contrasted with transparent liquid dye tints that leave the live timber edge visible underneath.
Router Sled / CNC Slab Flattening
Milling both faces of a rough-sawn hardwood slab dead flat and parallel before moulding, and again after the final resin pour has cured, before progressive orbital sanding from 80 grit up to 3,000 grit.
Seal Coat (Penetrating Tie Coat)
Brushing a thin coat of fast-curing epoxy onto the raw live edges and knots of a timber slab before the main river pour to seal microscopic wood pores and stop air bubbles escaping into the deep pour.
Shore D Hardness (80 to 85 Shore D)
The indentation hardness scale used for rigid plastics; fully cured deep-pour table epoxy reaches 80 to 85 Shore D after 7 to 14 days at 20C, hard enough to resist fingernails and everyday dining wear.
Spalted Beech & Figured Elm
Irish hardwoods prized for bespoke river tables: spalted beech shows dramatic black zone lines created by natural fungi in felled logs, while wych elm displays swirling interlocked grain and burr clusters.
Threaded Inserts & Slotted Steel Base Mounting
Heavy brass or steel threaded inserts set into the underside of the slab and bolted through elongated oval slots in the welded steel base plate so the solid timber side of the table can expand and contract across the seasons without splitting.
Vacuum Resin Timber Stabilisation
Consolidating soft, punky zones in spalted beech or burred timber with thin stabilising resin prior to the main pour so the timber machines cleanly and holds structural strength.
Questions we get asked
How much does an epoxy resin table cost in Ireland?
An Irish-made resin coffee table costs €450–€550. A live edge dining table for 6 in oak is €1,800–€3,200 before resin, and a 2.5 m river dining table in Irish timber with resin €4,000–€5,100.
Why are resin tables so expensive?
The slab, the resin and the time. A wide, dry hardwood slab is scarce; a river can take 10 litres of casting resin or more; and the resin goes in layers that each have to cure before the top is flattened, sanded and finished.
Does epoxy resin go yellow?
All epoxy yellows a little in strong sunlight over time: no epoxy is fully UV resistant. Table resins carry UV absorbers, and a polyurethane topcoat helps. Keep the table out of strong direct sun and it holds its look for years indoors.
