Wastes — How to Choose the Right One, and What Fits What

A waste is the fitting the plug sits in, at the bottom of a basin or a bath. It is not the trap and not the pipe. Almost no tap includes one, so it is the part most often remembered late — usually by the plumber, standing in your bathroom.

Everything here is click clack: press the plug to close, press again to open. There is no pull rod behind the tap and no linkage underneath, which means fewer parts to seize over the years and a tidier look at the back of the basin. It replaced the traditional pop-up waste for good reason.

Start here: three questions that decide it

• Basin or bath? They are not interchangeable. A bath waste is bigger, uses a G1 ½ thread against the basin's G1 ¼, and comes with a linked overflow assembly. See basin wastes or bath wastes.
• Does the bowl have an overflow? Look inside for a small slot near the rim. If it is there you need a slotted waste, whose side opening lets that water reach the drain. No slot means unslotted, solid-sided. This is the check that prevents most returns in this category. Baths almost always have an overflow, so bath wastes come with one as standard.
• What size is the hole? Measure the visible opening in the bowl, not the old plug. Basins are usually 60 mm at the cap; thicker ceramic ones take 70 mm, and 66 mm covers the gap between.

Matching the finish

A black tap above a chrome plug is the mismatch we see most often, and on a basin the two sit close enough together that it always gets noticed. We stock chrome, matt black and brushed brass across the range, plus white ceramic on the basin side — which sidesteps the question entirely, since a ceramic cap on a white basin reads as part of the bowl whatever colour your tap is.

None of our ELLSI bathroom taps include a waste. Two Deva taps do — the Ethos and the Adore Mini — so if you are buying either of those you do not need a separate waste at all.

What we do not stock

No traps. The trap is the U-bend below the fitting, holding water to block drain smells; it is a separate part and a sound existing one can almost always be reused when you change the waste. We also do not stock rod-operated pop-up wastes, kitchen sink wastes or shower wastes. Saying so here saves you a wasted click.
