Bathroom concealed waste trap Alca plast APS3 DN50 chrome

The Alca plast APS3 DN50 chrome concealed bathroom waste trap is a compact fixture designed for installation behind walls or under tiles to connect sanitary appliances to household wastewater systems. With a 50 mm outlet diameter and chrome-plated visible element, the unit provides a discreet, corrosion-resistant transition between shower trays, sinks or washbasins and the drainage line. The product is intended for concealed mounting where a neat finish and minimal visible hardware are required.

Advantages

The concealed design allows the waste trap to be hidden from view, preserving bathroom aesthetics while maintaining full functionality. The standard 50 mm connection ensures compatibility with common drainage pipes. The chrome finish offers corrosion resistance and easy cleaning for the exposed part, and the compact geometry simplifies installation in limited cavities behind walls or underfloor screeds.

How to use

Position the waste trap within the installation cavity so that the outlet aligns with the drainage pipe.

Use compatible DN50 fittings and ensure accessible inspection points where possible.
