Cheap Pontoon Flooring Ideas: Pros, Cons, and Buying Guide

Replacing the carpet on a 22-foot pontoon costs anywhere from $300 to $4,500 depending on the material, and most of that range comes down to a single choice between budget DIY and showroom-grade marine flooring. Cheap pontoon flooring ideas are abundant, but only a handful actually survive the UV, salt spray, dragging anchor chains, and dropped tackle that define real pontoon use. This guide ranks the legitimate budget options by installed cost, expected lifespan in real conditions, and what they look like after two summer seasons in the sun.

The Constraints That Make Pontoon Flooring Different

Pontoon floors face a brutal environment that does not exist on home interior floors. UV exposure breaks down most polymers and lifts adhesives. Salt or chlorinated water reaches into every seam. Wet bare feet, dragging anchor chains, and cooler corners deliver impact and abrasion that residential flooring is never designed for.

The cheapest flooring is rarely the cheapest answer over five years because failures mean a complete teardown. Spend a little more upfront for materials that genuinely handle the use case.

Option 1: Marine-Grade Carpet ($2-$5 per sq ft DIY)

Marine carpet from Aqua Turf, Dorsett, or Lonseal at 16-22 oz face weight runs $5-$12 per linear foot in 6-foot widths. For a 22-foot pontoon (roughly 120-140 sq ft of deck), the materials cost $250-$650.

Marine carpet installs with marine carpet adhesive (West Marine, 3M Marine, or Henry equivalents) over a clean plywood deck. The work is straightforward DIY with utility knife, scissors, and a stiff roller. Expect 5-8 hours for a typical pontoon.

Realistic lifespan in moderate use is 4-7 years. UV fades the color, mildew starts at seams that retain moisture, and the carpet flattens in high-traffic zones. The replacement cycle is shorter than EVA foam but the price is lower per cycle.

Option 2: Marine-Grade Vinyl Roll ($4-$9 per sq ft DIY)

Marine vinyl roll goods from Lonseal Lonmarine, Nautolex, or Naumar deliver a wood-look or solid-color surface with embossed texture for slip resistance. Roll widths are typically 6 feet, lengths are custom-cut from rolls. Materials run $400-$1,200 for a 22-foot pontoon.

Vinyl installs with marine vinyl adhesive over clean plywood. The seams need careful butt-joint treatment to prevent water intrusion. Some installers use a thin bead of marine sealant under seams as added protection.

Lifespan in moderate use is 8-12 years. UV does fade colors over time, but the dense vinyl resists mildew and cleans easily with a hose and mild soap. This is the workhorse middle-tier option.

Option 3: EVA Foam Decking DIY Sheets ($6-$10 per sq ft DIY)

Off-brand EVA foam decking from Amazon, eBay, and budget marine suppliers runs $4-$8 per sq ft for raw sheet material in 23×95-inch or 47×95-inch panels. For a 22-foot pontoon, materials cost $500-$1,100 if you template and cut yourself.

This is the cheap version of Gatorstep or SeaDek. You template the deck with poster board, transfer the patterns to the foam, and cut with a sharp utility knife or laser/CNC if you have access. The 3M acrylic adhesive backing sticks to clean fiberglass, aluminum, or sealed plywood.

Quality varies dramatically. Premium imports from established Chinese factories deliver 6mm foam with reasonable adhesive and 5-7 year service life. Cheap pallet stock at $4 per sq ft uses 4mm thin foam and weak adhesive that lifts within 1-2 seasons in hot, sunny climates.

Option 4: Peel-and-Stick Vinyl Plank ($3-$6 per sq ft DIY)

Residential peel-and-stick vinyl plank works on pontoons in limited circumstances. Indoor LVP is not designed for marine use, but it can deliver 3-5 years of service on a covered pontoon or one stored under a boat cover when not in use.

The install is fast and the wood-look visual is striking, but the seams between planks are vulnerable to water intrusion. Use marine sealant along all exposed edges and at every seam to extend life.

This option is realistic for buyers on a tight budget who keep the boat covered and want the cosmetic upgrade. Skip it for boats used daily or moored uncovered.

Option 5: Painted Plywood Deck ($1-$2.50 per sq ft)

The absolute cheapest option is replacing damaged plywood, sealing with marine epoxy, and painting with two coats of marine deck paint (Interlux Brightside, Pettit EZ-Decks, or Total Boat Wet Edge). Materials for a 22-foot pontoon run $150-$300.

This works for a true budget refit on a project boat. Add a textured non-slip additive to the topcoat for traction. The painted finish is durable enough for daily use, easy to refresh annually, and reads honest rather than tacky.

Lifespan is 2-4 years before the paint shows wear and needs a refresh coat. Annual touch-up costs $40-$80 in materials.

Option 6: Snap-Together Tile (PlasDECK, Tek-Dek) ($3-$8 per sq ft DIY)

Modular snap-together deck tiles from PlasDECK, Tek-Dek, or generic equivalents click together over a clean deck. The product floats unbonded or attaches with limited adhesive. Cost runs $400-$1,000 for materials on a 22-foot pontoon.

The big advantage is replaceability. Damaged tiles snap out and replace individually for $5-$15 each. The disadvantage is that water intrudes between tile joints and reaches the substrate, which can rot plywood over time.

Best applied over a sealed waterproof substrate (fiberglass deck, sealed marine plywood, or aluminum). Lifespan is 7-12 years for the tiles, with individual replacements ongoing.

Realistic Total Project Cost Comparison

For a typical 22-foot pontoon (120-140 sq ft of deck), here is what DIY installation actually costs:

• Painted plywood: $150-$300 plus annual touch-ups. Cheapest by far.
• Marine carpet: $250-$650, redo every 5-7 years.
• Peel-and-stick LVP: $400-$700, redo every 3-5 years.
• Snap-together deck tile: $400-$1,000, individual tile replacements ongoing.
• Marine vinyl roll: $400-$1,200, redo every 8-12 years.
• EVA foam DIY (budget brand): $500-$1,100, redo every 5-7 years.

For long-term cost-per-year, marine vinyl roll usually wins. For lowest upfront cost, painted plywood. For best looks at budget price, EVA foam from a reputable seller.

Prep Work That Saves You Money

Whatever flooring you choose, prep determines whether it lasts. Remove every screw, bracket, and cleat first. Strip the old flooring completely. Repair or replace any rotten plywood. Clean the substrate with acetone or denatured alcohol. Let everything dry 24-48 hours before applying new material.

Skipping prep is the single biggest source of pontoon flooring failures. The materials work as advertised when applied to clean, dry, sound substrate.

What to Avoid

Skip indoor carpet (not UV-stable), residential vinyl planks without marine sealing, untreated plywood as a finish surface, and any “marine” product without verifiable manufacturer documentation. The flooring section of a marine supply store is the right place to source materials. Saving $50 on questionable Amazon imports usually costs more in early replacement than it saves on initial purchase.
