Shower trays take daily use and occasional hard knocks. Chips from dropped shampoo bottles, cracks from excessive weight or flex, surface scratching and the gradual yellowing of older acrylic are all common issues. Understanding what’s repairable and what the process involves helps homeowners make informed decisions rather than rushing into expensive full shower replacement. This guide covers the main shower tray materials and their repair options.
Acrylic Shower Tray Repair
Acrylic shower trays are the most common type in UK bathrooms and the most straightforward to repair. They are lightweight, available in a wide range of sizes and shapes, and relatively affordable — but the acrylic surface can chip and scratch more readily than stone resin or ceramic.
- Chip repair — chips in acrylic shower trays are repaired with colour-matched acrylic filler compounds applied in layers, cured and polished to a smooth finish matching the surrounding surface; white trays are the most straightforward, coloured trays require careful colour matching
- Crack repair — small cracks can be filled with compatible filler, but if the crack extends through the full thickness of the tray and relates to flex in the supporting structure, the structural issue must be addressed first (re-bedding or providing additional support under the tray)
- Surface scratching — fine scratches can be polished out with appropriate acrylic polish; deeper scratches require filling
- Yellowing — age-related yellowing of acrylic shower trays is difficult to reverse by surface treatment; respraying with appropriate coatings can refresh the appearance where yellowing is uniform
Stone Resin Shower Tray Repair
Stone resin (or mineral resin) shower trays are a premium alternative to acrylic — heavier, more rigid and with a more luxurious feel. They are also more durable but not immune to damage:
- Chip repair — chips in stone resin trays are repaired using colour-matched stone repair compounds; the texture of stone resin (which has a slightly rough, matt finish) must be replicated in the repair for the best result
- Crack repair — stone resin cracks are filled with compatible epoxy or repair mortar; large cracks may indicate structural problems with the support beneath the tray
Ceramic and Porcelain Shower Tray Repair
Ceramic and porcelain shower trays are the most durable type and typically found in higher-end bathroom installations or older bathrooms. Their repair follows the same principles as ceramic tile repair:
- Chip repair — colour-matched ceramic filler and glaze coating applied and polished; the challenge is matching the specific white or off-white shade of the original ceramic
- Crack repair — hairline cracks filled with colour-matched resin; larger cracks may compromise the waterproofing of the tray and require more extensive remediation
