Yes—you’re looking for a street bench with real drainage, not just a smooth seat that holds water. For street bench drainage, the most reliable design is a slatted bench seat. Wood, aluminum, or coated steel slats with open gaps let rainwater run straight through, so you get no rainwater pooling on the surface. Those gaps also allow airflow, which makes a quick-dry bench after a storm.
Perforated or expanded metal seats are another good option for outdoor bench drainage. The holes act like small drains, especially if the seat has a slight slope or a crowned profile. Even a 2–3 degree pitch helps water shed to the edges.
Some recycled plastic and concrete benches include molded drain grooves or channels. They work well if the grooves are wide enough and you keep them clear of leaves and dirt.
What to avoid: solid one-piece seats with no slope, deep recesses, or tightly butted wood planks with no gap. Those are the benches that collect water and stay wet for hours.
If you already own a bench, you can often improve it. For wood or composite slats, drill a few 6 mm drain holes at the low spots. For metal, adding small slots may be possible. Just check the warranty before modifying anything.
In short: choose a slatted, perforated, or slightly sloped seat with open drainage paths, and you won’t be sitting on a puddle after rain.
