Concrete Shower Tray 80x80 - Anti-Slip for Outdoor Use
80 × 80 concrete shower tray: the outdoor shower solved in a single piece
A pool shower often ends up as a permanent puddle or a ring of mud that gets tracked straight back into the water. This concrete tray, 80 × 80 cm and 76 kg, prevents that because it already comes pre-sloped toward a central 66 mm drain: the water is collected and drains away instead of pooling at the bather's feet.
✅ Key advantages
Square 80 × 80 cm format: enough surface to shower comfortably without eating into the pool surround.
Central 66 mm drain: a wide diameter that doesn't clog with sand or leaves the way 40 mm drains do.
Factory-built slope: all four planes drain toward the centre; there's no need to form the fall with mortar on site.
Class 3 anti-slip: the class required by Spanish building code CTE DB-SUA for wet outdoor areas and pool perimeters.
76 kg of dead weight: holds itself down by gravity with no anchors; it won't shift with use or wind.
Two neutral finishes: white and grey, which match any outdoor paving without having to get the tone right.
🏗️ Recommended uses
Access shower to the pool in private and community settings.
Foot-wash point where grass or gravel meets the pool surround.
Garden shower, barbecue area or porch.
Outdoor rinse-off at beach houses, campsites and rural accommodation.
Boot- and tool-cleaning point next to a vegetable patch or workshop.

🧰 Installation
Have the 66 mm drain pipe installed and tested before laying the piece; with 76 kg on top there's no way to correct it afterwards.
Compact a 10-15 cm base of crushed aggregate under the tray's footprint; on loose fill it will settle unevenly by the first winter.
Spread a fresh mortar bed of 3-4 cm and lower the tray with two people, without dragging it on its edge.
Level with a rubber mallet and check with a spirit level that water flows to the drain and that the tray doesn't tip toward the pool.
Seal the perimeter with an elastic polyurethane joint, leaving 5-8 mm of clearance for expansion.
Wait 48 hours before running water or walking on the loaded tray.

💡 Professional tip: the classic mistake is leaving the tray flush with the paving and sloping toward the pool. Raise the tray 1 cm above the surrounding paving and check with a level that the runoff goes outward: soapy water and sunscreen that flow back into the pool spike chlorine consumption and clog the filter every weekend. If it's bedded on existing paving, use a C2 adhesive rated for outdoor and immersion use; indoor-grade adhesive hydrolyses under constant moisture and within two seasons the tray starts to rock. And always leave a perimeter expansion joint: without it the paving pushes against the tray in summer and opens a crack at its thinnest edge.
Frequently Asked Questions
¿Qué diámetro de desagüe lleva?
66 mm central. Es más ancho que el habitual de 40 mm y por eso tolera mejor la arena y las hojas que arrastra un bañista al salir del agua.
¿Hay que darle pendiente en obra?
No. Los planos vienen inclinados de fábrica hacia el sumidero. Solo hay que nivelar la pieza y comprobar que la escorrentía va hacia fuera del vaso.
¿Se puede instalar sobre un pavimento ya colocado?
Sí, si el soporte está firme. Debe recibirse con cemento cola C2 apto para exterior e inmersión; el adhesivo de interior no aguanta la humedad permanente.
¿Necesita anclajes?
No. Con 76 kg apoya por gravedad sobre una cama de mortero de 3-4 cm.
¿Es resbaladizo con los pies mojados?
Tiene clasificación clase 3, la que pide el CTE DB-SUA para superficies exteriores húmedas y bordes de piscina.
¿Aguanta el agua clorada o salada?
Sí. Es hormigón para intemperie. Conviene aclararlo con agua dulce al cierre de temporada si la piscina es de cloración salina.
¿Cuántas piezas trae el palet?
Cuatro unidades, 320 kg en total. Prevea medio de descarga adecuado.
¿Puedo usarlo dentro de casa?
Está pensado para exterior. En interior su peso complica la instalación sobre forjado y no aporta ninguna ventaja.
