What a custom dining table costs in Adelaide

A custom dining table in Adelaide costs $2,800 to $9,000, and most land between $3,500 and $5,500. The useful part is not the range, it is knowing which decisions move it. Species and base design move a quote hard. Length, the thing almost everybody worries about first, barely moves it at all.

This page breaks the number down by specification. If you want the wider picture across every piece type, that sits in what custom furniture costs in Adelaide, and the full sizing detail lives on the custom dining tables page.

What a table costs, by size and species

These are total delivered prices in Adelaide metro for a solid timber table on a 4-leg base with a 32mm top and a hand-applied finish.

| Length | Seats | Tasmanian oak | American oak | Blackwood | | --- | --- | --- | --- | --- | | 1,600mm | 6 (snug) | $3,000 to $3,600 | $3,400 to $4,200 | $4,000 to $5,200 | | 1,800mm | 6 (comfortable) | $3,200 to $3,900 | $3,700 to $4,600 | $4,400 to $5,800 | | 2,100mm | 8 | $3,600 to $4,400 | $4,100 to $5,200 | $4,900 to $6,500 | | 2,400mm | 10 | $3,900 to $4,900 | $4,500 to $5,800 | $5,400 to $7,200 | | 2,700mm | 12 | $4,400 to $5,600 | $5,100 to $6,600 | $6,100 to $8,400 |

Read across a row before you read down a column. Moving from 1,800mm to 2,400mm in Tasmanian oak costs about $700. Staying at 1,800mm and switching from Tasmanian oak to blackwood costs about $1,600. The table you want is almost always longer than the one you were about to order, and in a plainer species.

Size adds far less than people expect

A 2,400mm table has 33% more surface than an 1,800mm one. It costs 15% to 20% more, not 33% more, because only 1 of the 4 cost inputs actually scales.

• Timber volume scales directly with length. This is the part that grows.
• Machine setup does not. Thicknessing 6 boards and thicknessing 8 boards is the same setup and nearly the same time at the machine.
• Joinery does not. A frame has 4 corners regardless of how long the rails are, and the mortises take the same time to cut.
• Finishing barely does. 3 to 5 coats with cure time between each is a calendar problem more than an area problem.

The practical consequence: order the size the room takes, not the size your budget assumes. Working out what the room takes is a separate exercise, and the clearance rules that decide it are set out in measuring for a custom dining table.

The base is where the hours go

The top is the visible half of the table and the cheap half to build. The base carries every load, has to stay square under a 60kg to 90kg top, and takes most of the joinery time.

| Base type | Added cost vs 4 legs | Why | | --- | --- | --- | | 4 straight legs, mortise and tenon | baseline | 4 identical joints, fast setup | | Tapered or splayed legs | $150 to $350 | Angled shoulders, more hand fitting | | Steel frame with timber top | $300 to $1,100 | Outsourced fabrication and powder coat | | Trestle with a stretcher | $400 to $900 | 2 assemblies plus a through-wedged stretcher | | Twin pedestal | $700 to $1,600 | Each pedestal is a small cabinet | | Single pedestal | $900 to $1,800 | All stability from 1 point, needs a heavy foot | | Cantilevered top | $1,200 to $2,400 | Engineered steel core, no margin for error |

A single pedestal is the base most people want, because it gives every seat clear legroom. It is also the hardest to build well: the whole table's stability comes from 1 joint and 1 foot, so the timber has to be heavier, the joint bigger, and the foot wider than it looks in a photo.

Top thickness: 32mm or 45mm

These are 2 different tables and quotes rarely make that obvious.

A 32mm top is standard. It is stable to 2,000mm on a properly braced frame, sands back once over its life, and keeps the table visually light. A 45mm top costs $400 to $900 more, resists deflection over a long span, gives you 2 full re-sands, and reads as a much more substantial piece. Over 2,200mm, take the 45mm. Under 2,000mm, put the money into the finish instead.

If a quote does not state the top thickness, that is the first question to ask. It is the most common place a cheap quote quietly saves money.

Solid or veneered

A solid top and a veneered top can look identical on delivery day and cost 40% apart. Veneer over a stable substrate is genuinely good engineering for wide cabinet doors, because it will not move. For a dining tabletop that will be scratched, wet, sanded and re-finished across 20 years, solid is the correct call: a veneer is 0.6mm thick and a single deep sand goes through it.

The species itself matters as much as the construction. Which one suits an Adelaide house is covered properly in choosing timber for custom furniture, and the reference data on Australian species is published by WoodSolutions.

Extensions add $600 to $1,800

An extension is the single most expensive feature you can add to a dining table, and it is worth understanding why before you decide.

• Draw-leaf with a stored leaf, $600 to $900. The leaf lives in a cupboard. Cheapest and most reliable.
• Runner-mounted with an insert leaf, $900 to $1,300. The top splits and slides on steel runners, the leaf drops in.
• Butterfly leaf, $1,300 to $1,800. The leaf folds in half and hides inside the table. Beautiful, and 3 times the setting-out.

The extra leaf must be finished on both faces and stored flat in the same room as the table. A leaf kept in a hot garage over an Adelaide summer will come back a different width from the table it belongs to.

What $4,500 actually buys

Working a quote backwards is the fastest way to tell whether it is honest. On a $4,500 solid Tasmanian oak table from an established Adelaide workshop:

| Cost line | Amount | Detail | | --- | --- | --- | | Timber | $900 to $1,400 | Bought rough-sawn, 30% to 40% lost to machining and defect | | Consumables | $250 to $500 | Finish, abrasives, glue, hardware, packaging | | Labour | $2,200 to $2,800 | 35 to 50 hours across milling, joinery, assembly, sanding, 3 to 5 coats | | Overhead and margin | the remainder | Workshop, insurance, delivery, profit |

When a quote lands well under the band, the saving came out of 1 of 3 places: the timber (thinner, veneered or a lower grade), the joinery (screwed and plugged rather than cut), or the finishing hours (2 coats instead of 5). All 3 are legitimate ways to hit a budget. They are only a problem when nobody tells you.

Where to spend, and where to save

Spend on the finish, the top thickness if the table is long, and the way the top is fixed to the base. That last one should involve buttons or z-clips that let the top move; screws driven straight through a fixed rail will split a top in an Adelaide summer.

Save on species before you save on size, save on base complexity before you save on construction, and skip the extension unless you will genuinely use it more than twice a year. If the budget still will not stretch, the honest comparison against a retail piece is set out in custom versus flat-pack, and the per-metre logic that governs fitted work is in what a built-in wardrobe costs.
