What Resin Thickness is Best for Shower Trays?

← Back to Which resin is used for a shower tray?

Choosing the correct resin thickness is essential for building or refurbishing a shower tray, ensuring durability, water resistance, and a quality appearance. Your choice will depend on whether you’re making a solid tray or applying a decorative or protective surface layer.

Recommended Resin Thickness by Project Type

For solid or deep-cast shower trays, opting for a thicker resin layer is essential to provide sufficient strength and stability. Resins such as Epoxytable 10-Ten can be poured up to 10cm deep in a single application, making it ideal for robust, freestanding trays. For medium-depth trays, EpoxyTable 5-Five allows up to 5cm thickness, providing a reliable solution for projects not requiring maximum depth.

If you’re refreshing an existing tray or want a decorative and protective layer, thinner resin coatings from 1 to 2cm are generally recommended. Products like “Trasparente” epoxy resin are designed for these applications, offering excellent clarity and surface hardness.

Practical Tips for Application

• Match resin and thickness to the tray type: deep pour resins for solid trays, surface resins for coatings.
• Follow mixing and pouring instructions to prevent bubbles and achieve a smooth, even finish.
• Pour thick layers in stages if recommended by the manufacturer—especially for castings beyond 5cm—to avoid overheating and ensure full curing.
• For best results, allow adequate curing time, and avoid exposing the resin to high temperatures until fully hardened.

When Resin Thickness Really Matters

Choosing the right thickness is crucial in any situation where the shower tray will experience heavy use, impact, or needs to support significant weight. Too thin a layer on a load-bearing tray risks structural failure, while excessive thickness for mere surface coatings leads to unnecessary cost and possibly curing issues.
