Basin wastes and bottle traps for basins, shower trays and urinals — choose from over 40 models by DutchLine, Aloni and Isvea, with prices from around £15. Whether you need a click-clack waste for a basin or a flexible bottle trap for a shower tray, the right choice comes down to a few straightforward factors.
Which bottle trap or basin waste suits your setup
The most important starting point is the connection size. Basin bottle traps typically use a 5/4" waste outlet and drain via a 32 mm or 40 mm pipe. Check this before ordering, as a 32 mm bottle trap will not fit a 40 mm waste pipe. The Aloni flexible bottle trap Ø32 mm and the Ø40 mm variant are both available, so measure your existing waste outlet before making your choice.
Next, choose your preferred operation type. A basin waste with hollow screw threads into the waste outlet of the basin and is lifted manually. A click-clack waste such as the DutchLine Luxe Clickwaste 5/4" in chrome or the Aloni Clickwaste Push-Up in brushed copper opens and closes with a single press. For finishes, you can choose from chrome, brushed gold (PVD), brushed copper and bronze copper — pick whichever complements your tap and furniture.
Installation: check the clearance beneath your basin
A common mistake is ordering a bottle trap without measuring the available clearance beneath the basin. A standard bottle trap typically requires between 180 and 200 mm between the waste outlet of the basin and the floor or cabinet shelf. If space is tight, opt for a floor pipe bottle trap such as the DutchLine Sifon Vloerbuis in brushed bronze copper, which requires far less depth and doubles as a visible design feature.
Frequently asked questions
What is the difference between a bottle trap and a basin waste?
A basin waste seals the waste outlet and sits in the basin itself. A bottle trap is the S- or U-shaped section of pipework beneath it that forms a water seal and prevents sewer odours from entering the room. You need both for a fully functioning waste system.
What is a basin waste with hollow screw?
This is a waste where a hollow screw passes through the waste outlet of the basin and is secured with a back nut on the underside. It is the traditional fitting method, independent of any click mechanism. These wastes are suitable for basins without an overflow as well as those with one — just make sure you select the correct variant for your basin.
How do I choose the right bottle trap for a urinal?
For a urinal you will need a dedicated urinal bottle trap, such as the Aloni urinal bottle trap horizontal/vertical, which accommodates two waste directions. Check whether your waste outlet exits through the wall (horizontal) or through the floor (vertical), as this determines which orientation you require.
