Shower Tray Sheet – The Foundation of Reliable Shower Bases
What Materials Are Used for Shower Tray Sheets?
The choice of material directly affects the tray's strength, weight, thermal insulation, and cost. We offer three primary grades:
ABS (Acrylonitrile Butadiene Styrene) – The most popular choice for residential showers. It provides excellent impact resistance, good rigidity, and a smooth surface that accepts acrylic cap layers or gel-coat finishes. ABS is easy to thermoform and offers a warm touch underfoot.
HIPS (High-Impact Polystyrene) – A cost-effective alternative with good dimensional stability and ease of forming. It is often used for budget-friendly trays and is compatible with decorative laminates.
Acrylic / PMMA (Polymethyl Methacrylate) sheets – Premium-grade material with superior gloss, UV resistance, and scratch resistance. Acrylic shower trays are often reinforced with ABS backing for extra strength, giving a high-end, glossy finish that resists yellowing over time.
We also supply multi-layer co-extruded sheets that combine a durable acrylic wear layer with an ABS or HIPS core, balancing aesthetics and structural performance.
Processing Methods for Shower Tray Sheets
To turn a flat sheet into a functional shower tray, we support two main manufacturing approaches:
Vacuum Thermoforming (our specialty) – The sheet is heated to a precise forming temperature, then drawn onto a male or female mold using vacuum pressure. This method produces complex shapes with integrated slopes, raised edges, and non-slip textures in a single cycle. It is highly efficient for medium-to-large production runs and allows for consistent wall thickness distribution.
Pressure Forming – For more intricate details or tighter tolerances, we also use positive air pressure to force the heated sheet against the mold. This yields sharper corners, crisper drain holes, and better surface finish than standard vacuum forming.
CNC Trimming & Drilling – Post-forming, we machine the tray edges, cut drain openings, and drill installation holes with high-precision CNC equipment to ensure perfect fitment.
Color Options – Customize to Any Bathroom Style
We understand that bathroom aesthetics matter. Our shower tray sheets are available in:
Standard solid colors – Glossy white, off-white, cream, light gray, and charcoal black (most popular).
Marble-effect & stone patterns – Digital-printed or in-mould decorated sheets that mimic natural stone, granite, or terrazzo.
Custom RAL or Pantone colors – We can match your specific brand color upon request for minimum order quantities.
Matte or gloss surface finishes – Non-slip textured or smooth high-gloss, depending on your preference.
All pigments are UV-stable and fade-resistant to maintain their appearance over years of daily use.
The Role / Function of a Shower Tray Sheet
The finished tray made from this sheet serves several critical functions:
Waterproof containment – It creates a watertight basin that directs all shower water to the central drain, preventing leaks into the subfloor.
Structural support – The rigid, formed sheet provides a stable standing platform that distributes weight evenly.
Slip resistance – With custom-textured molds, the surface can be engineered with anti-slip patterns for safety.
Thermal insulation – Plastic sheets feel warmer underfoot than ceramic or stone, enhancing shower comfort.
Quick installation – Lightweight formed trays reduce labor time compared to tiled mortar beds.
Hygiene – Seamless, non-porous surfaces prevent mold and bacteria growth, making cleaning effortless.
Why Choose Us? – Your One-Stop Partner for Both Sheet Supply & Vacuum Forming
Most suppliers only sell raw sheets or only offer forming services. We are different – our factory integrates both plastic sheet extrusion and vacuum thermoforming capabilities under one roof.
Total quality control – From resin pellets to the finished tray, we oversee every step. This means no mismatched sheet thickness, no inconsistent forming temperatures, and no finger-pointing between suppliers.
Cost savings – By eliminating the middleman and logistics between sheet maker and former, we pass on significant savings to you.
Faster lead times – No waiting for sheet delivery from external vendors. We schedule extrusion and forming in sync, reducing your project timeline by up to 30%.
Flexibility – We can run small-batch trials with our in-house sheet extrusion line, then scale to mass production with the same material recipe – ensuring prototype-to-production consistency.
Technical support – Our engineers advise on optimum sheet gauge, material grade, and mold design to achieve the best draw ratio, corner radii, and part strength for your specific tray dimensions.
Sustainability – We recycle edge trimmings and off-cuts back into our extrusion process, minimizing waste.
Whether you need a standard 900×900 mm square tray, a large 1800×900 mm rectangular pan, or a custom curved design, we deliver from sheet extrusion to finished vacuum-formed tray – all with traceable quality, competitive pricing, and on-time delivery.
