Ask three marinas what custom EVA decking costs and you'll get three wildly different numbers — because "EVA decking" can mean a $60 self-adhesive sheet or a $4,000 professionally installed deck. This guide breaks the price apart layer by layer, so you know exactly what you're paying for before you request a quote.
The quick answer (2026 typical ranges)
- Blank EVA foam sheets (brushed finish, 5–6 mm, self-adhesive): $4–9 per sq ft, material only. You cut and fit it yourself.
- Custom CNC-cut kits (grooved teak-look lines, boat name or logo engraved, made to your deck template): $12–22 per sq ft equivalent — for a typical 20–24 ft center console that lands around $350–900 per kit factory-direct.
- US retail, professionally installed (the big-name brands): $25–45+ per sq ft installed. Same foam, same CNC machine — the difference is brand, distribution layers and local labor.
Buying factory-direct typically lands 40–60% below US retail for the identical material and cut quality. That gap is exactly why refit shops and boat builders have moved their deck supply overseas.
What actually drives the price
Two decks of the same size can differ 3× in cost. The variables:
- Thickness — 5 mm is the workhorse; 6 mm adds cushion (and cost) underfoot.
- Single vs dual-color — two-tone decks laminate two layers before cutting; expect a 20–35% premium over single color.
- Surface texture — brushed is standard; grooved teak-look lines require CNC time.
- Engraving — a laser-cut boat name or logo adds a small setup fee, not a re-quote.
- Coverage & complexity — a flat cockpit floor is cheap; a curved swim platform with many cutouts wastes material and machine time.
The refit shop math
A shop quoting a customer $3,200 for a full deck install might pay $1,100–1,400 factory-direct for the same custom kit. Keep the labor margin, pass part of the saving to the customer, and the job gets easier to sell — while you still clear more than buying domestic blank material and cutting in-house.
What a supplier needs from you
Custom EVA is made to your boat, so quote accuracy depends on your input:
- A paper template, traced deck outline, or CAD/DXF file of the deck sections
- Color choice (single or dual-color) and texture preference
- Boat name / logo file if you want engraving
- Thickness: 5 mm or 6 mm
Clear photos of the deck area help the factory flag tricky curves before production, not after.
At WOW's custom EVA decking line, kits are CNC-cut to your template from 5–6 mm marine-grade foam, MOQ from 10 pieces, typical lead time 15–25 days including ocean freight quotes. Send your deck template for a same-week quote →
Price by boat size: a worked table
To make the ranges concrete, here's what the same 5 mm dual-color grooved deck costs in three scenarios (2026 indicative, mid-range complexity):
| Boat | Deck area | DIY sheets | CNC kit, factory-direct | US installed |
|---|---|---|---|---|
| 16 ft skiff | ~45 sq ft | $200–400 | $550–950 | $1,100–2,000 |
| 22 ft center console | ~75 sq ft | $350–650 | $900–1,650 | $1,900–3,400 |
| 28 ft walkaround | ~110 sq ft | $500–950 | $1,300–2,400 | $2,800–5,000 |
Treat these as planning numbers, not quotes — complexity, engraving and shipping move each line. But the pattern holds: the factory-direct CNC kit usually prices between one-third and one-half of a domestic installed job.
Sheet, kit or full install — which should you buy?
Buy sheets if the deck is flat, you own a sharp knife and a straightedge, and the boat is a workboat where "neat" beats "perfect." Buy a kit if there are curves, cutouts around hatches, or a boat name involved — CNC precision is worth the money the moment shapes get complex. Pay for install only if you're selling the boat or simply value your weekend more than the difference; the material is identical either way.
The landed-cost line most buyers forget
Factory-direct pricing is FOB-plus-freight, so budget the full picture: ocean freight (EVA is light — a full kit is rarely more than 15–25 kg), any import duties, and a week or two of buffer over the production lead time. Even stacked, landed cost usually stays far under domestic retail — but quoting a customer before you have the landed number is how shops eat the difference.
Frequently asked questions
Is EVA boat decking actually waterproof?
Yes — EVA foam is closed-cell, so it doesn't absorb water. The self-adhesive backing is the part to keep an eye on: surface prep (clean, dry, degreased) matters more than the glue itself.
How long does it last?
Expect 5–7 years of sun and foot traffic before visible wear in most climates. UV-stabilized grades last longer; covered storage extends life further.
Can I install it myself?
Flat sections, easily — peel, position, press. Curved sections benefit from a heat gun and patience. Most DIY failures come from rushing the surface prep.
Will it damage my gelcoat when removed?
Heat softens the adhesive; removal with a plastic scraper and citrus solvent is standard practice and gelcoat-safe in the vast majority of cases.
Does it get hot underfoot?
Less than fiberglass or gelcoat — light colors stay comfortable barefoot in full sun, one reason it's popular on family boats.
