The Floplast White Shallow Bath Trap with Eye 20 mm Seal × 40 mm (TSB42) is a compact waste trap designed for use with bathtub installations, particularly where space below the bath is limited. It combines reliable drainage performance with a shallow profile and an integrated access “eye” for easy maintenance.

Function & Purpose

This bath trap collects wastewater from the bath drain and channels it into the 40 mm waste pipe while maintaining a 20 mm water seal. The water seal acts as a barrier against sewer gases and unpleasant odours rising up through the drainage system. The shallow design allows installation in tight spaces where a standard, deeper trap might not fit.

Compatibility

The trap is sized for 40 mm waste pipework, which is standard in most conventional domestic bath installations. It connects securely to the bath waste outlet and downstream drainage using compatible pipe and fittings.

Design & Build Quality

Finished in white for a clean appearance under the bath, the TSB42 is made from durable plastic that resists corrosion and everyday wear. The shallow profile helps accommodate reduced floor or void space, and the integrated “eye” access point allows plumbers or homeowners to inspect, clean, or clear the trap without fully dismantling the assembly.

Ideal Applications

This shallow bath trap is ideal for bath installations with limited space below the tray, such as in loft conversions, boxed-in installations, or where joist height is low. It’s well suited for new bathrooms, renovations, and replacement projects where a conventional trap won’t fit but reliable odour control and drainage are still needed.
