Solid plastic has earned a loyal following among facilities teams, and the reason sits in how the panel is built. High-density polyethylene or HDPE toilet partitions are one material through the full thickness, with the color running all the way through rather than sitting on the surface.
The advantage shows up everywhere downstream. There is no core to absorb water, no face to peel away from a substrate, and no coating to chip. Every durability claim in this article traces back to this one property.
Manufacturer Scranton Products backs its solid plastic partitions with a 25-year warranty. Understanding what the warranty rests on makes it easier to price solid plastic against the alternatives and to see where the material pays you back hardest.

Why Homogeneous Material Behaves Differently
HDPE partitions are fabricated from polymer resins compounded under high pressure, forming a single component. The result is waterproof and nonabsorbent, with a self-lubricating surface.
Compare it against the alternatives and the pattern is clear. Painted steel rusts outward from a chipped edge. Laminate swells at the bottom and lifts. Composite panels separate where the core meets the face. Each of those failures begins at a boundary between two materials, and solid plastic has no boundary to begin at.
Work through what the material removes from your maintenance schedule. Solid plastic will never rust, so a chipped edge stays a chipped edge instead of becoming a corrosion path. It will not delaminate, because nothing is laminated. It never needs painting, since the color is the material rather than a finish applied to it.
The same property handles moisture. HDPE does not absorb water, which means it resists mold and mildew rather than feeding them. In a pool house, a locker room, or a restroom getting hosed down nightly, the material shrugs off conditions which shorten the life of a composite panel.
Impact resistance follows. Solid plastic resists dents, scratches, and corrosion, and it holds its composition rather than weakening over time.
Solid plastic sits in the middle of the price range. It costs more than powder coated steel and less than stainless, and the argument for it has little to do with the panel price. Facilities teams reach for it when the replacement cycle matters more than the purchase order, since a restroom refitted twice in twenty years costs more than one refitted once.
Construction and Heights
Doors, panels, and pilasters are 1 inch (25 mm) thick with all edges rounded to a radius. The rounded edge matters more than it sounds. It removes the sharp corner where a laminate partition takes its first chip.
Standard door and panel height is 55 inches (1397 mm). Taller options run 66 inches (1676 mm) and 72 inches (1829 mm), and both require a modular panel rather than the standard one. Confirm the panel type with your supplier before the order goes out, because the height change carries a component change with it.
Mounting follows the usual three configurations. Floor mounted with overhead bracing, floor to ceiling, and ceiling hung are all available.
Layout flexibility is worth confirming at takeoff. Solid plastic accommodates custom configurations and unusual spaces, which helps on renovation work where the existing rough-in dictates the compartment sizes. Three ADA-compliant configurations cover the accessible positions.
Fire Rating and the Heat Sink
Solid plastic meets ASTM E84 Class B for flame spread and smoke developed. It passes NFPA 286, and carries an ICC Class B rating.
Where a project demands a higher rating, an aluminum heat sink fastens to the bottom edges of the panels. Raise the fire rating requirement early in the submittal. The heat sink is a specified component rather than a field addition, so catching it late means reordering.
HDPE Door and Panel Heights
| Door and panel height | Metric | Panel requirement | Where it fits |
| 55 in | 1397 mm | Standard panel | Most commercial restrooms, the default height |
| 66 in | 1676 mm | Modular panel required | Added privacy without going full height |
| 72 in | 1829 mm | Modular panel required | Schools, gyms, venues where sightlines matter |
Cleaning, Graffiti, and Power Washing
Schools and transit stations are where solid plastic separates itself from the alternatives. The surface is self-lubricating and resists marks from pens, pencils, markers, and other writing instruments. Graffiti sits on top of the panel instead of soaking into it.
Graffiti removal is the day-to-day version of the same story. Marks from pens, stickers, and most markers lift off the surface without taking a finish with them. A crew working a stadium restroom on a Monday morning clears a weekend of tagging without a repaint scheduled behind it.
Maintenance crews handle solid plastic with tools other materials will not tolerate. The panels stand up to power washing, steam cleaning, and common chemicals. A metal partition with a coating would lose its finish under the same treatment, and a laminate panel would swell at the edges.
One practical note for facilities teams. Because the color runs through the full thickness, a scratch shows the same color as the surface around it. A scratch in a coated panel shows the substrate underneath, which is why scratched metal looks damaged and scratched HDPE looks used.
Sustainability and Air Quality
Solid plastic partitions are 100 percent recyclable and free of VOC (Volatile organic compounds) emissions. Scranton Products holds GREENGUARD Gold Certification on its solid plastic line, which comes from third-party testing aimed at sensitivities to indoor air contaminants.
On projects chasing green building credits, those two points carry weight in the submittal alongside the 25-year warranty.
Frequently Asked
How long do solid plastic toilet partitions last?
Scranton Products warrants its solid plastic partitions for 25 years. The material does not rust, delaminate, or absorb moisture, which removes the common failure paths behind earlier replacement.
How thick are HDPE toilet partitions?
Doors, panels, and pilasters are 1 inch (25 mm) thick with all edges rounded to a radius.
What fire rating do solid plastic partitions carry?
ASTM E84 Class B for flame spread and smoke developed, a pass on NFPA 286, and ICC Class B. An aluminum heat sink fastens to the bottom edges where a project needs it.
Do HDPE partitions handle power washing?
Yes. They withstand power washing, steam cleaning, and common chemicals without losing a finish, because the color runs through the material rather than sitting on it.
