Honestly, when someone asks me this question, I can tell they’re already past the “just pick one that looks nice” stage. They’re thinking about the budget, the long-term headache of maintenance, and whether they’ll have to fight for replacement funds in three years. So let’s talk about it straight — not just the price tag, but the money you’ll spend over the entire life of that bench.
Right out of the gate, a standard metal street bench, like a cast aluminum or powder-coated steel one, will almost always cost you more upfront than a basic wooden bench. I’ve seen typical cast aluminum benches with a backrest start around $800 to $1,200 per unit, while a pressure-treated pine or even a simple hardwood slat bench might be in the $400 to $700 range. That can feel like a huge gap, especially if you’re ordering 20 of them for a park project. Many small towns or schools get drawn in by that lower wooden bench sticker price. I get it. I’ve done the same.
But here’s where the real story lives. A wooden bench in a public space takes a beating from sun, rain, snow, and every kid who decides to carve their initials into it. Even if you start with a good hardwood like teak or ipe — which, by the way, can easily push the upfront cost right up into that $1,000+ territory — you’re signing up for yearly maintenance. I’m talking sanding, sealing, oiling. If your maintenance crew is already stretched thin, they won’t do it. The bench will silver, crack, get splinters, and then someone will complain. Within five to seven years, you might be looking at replacing slats or the whole thing. The cheaper softwood benches? In a damp climate, you might get three to five years before they look shabby. So that $500 bench suddenly becomes $500 every five years, plus labor to assemble or fix it.
A well-made metal bench, specifically cast aluminum with a durable powder coat, is nearly a buy-it-once situation. I won’t say it’s zero maintenance — you’ll want to wipe off bird droppings and maybe tighten a bolt every few years — but it won’t rot, won’t warp, and won’t need sanding. I’ve seen aluminum benches in coastal parks that still look completely fine after 15 years. If we do the math over a 15-year period: that $1,000 metal bench might cost you $1,000 total. A $500 wooden bench replaced twice over the same period actually costs you $1,500, not counting the time someone spent hauling the old one away. Suddenly, the “expensive” metal option looks like the frugal choice.
But there’s a middle ground I always tell people to look at: recycled plastic lumber benches. They aren’t wood, but they give you that warmer, non-industrial look that some wooden bench lovers want, and they behave almost like metal in terms of zero maintenance. Their upfront cost usually falls right between cheap wood and cast aluminum, maybe $600 to $900. If your heart is set on a natural wood appearance, go for a high-quality hardwood and budget for the maintenance. Just don’t fool yourself into thinking the initial price tells the whole story.
Another cost people forget is installation. Metal benches are often heavier, which can be a good thing — they’re harder to steal or toss into a pond. But you might need more people or even a small lift to set them in place, especially if they are long steel frames. Wooden benches are generally lighter. If you’re anchoring them to a concrete pad, the anchor system costs about the same regardless. But if you’re just placing them on grass, a heavier metal bench will feel more stable.
So when someone asks me the difference in cost, I say: the metal bench costs more to buy and almost nothing to own. The wooden bench costs less to buy and will follow you with a quiet, yearly bill that shows up in maintenance staff time, replacement parts, and eventual early retirement. If your funding comes from a one-time grant that won’t cover future upkeep, the long-term argument for metal becomes even stronger. Make your choice with your eyes open.
