Pipe Fittings

Start by matching the kit to the number of bowls you have, there are Sauber kits specifically for 1, 1.5 and 2 bowl kitchen sinks, and hansgrohe offers single and double bowl waste kits. If you have a 1.5 bowl stainless steel sink, the Sauber Pipe Kit for 1.5 Bowl will give the correct connections and traps. Also check whether you need an overflow or separate waste for each bowl, as that affects whether you need a single or double waste kit.

A waste kit, like the Sauber or hansgrohe waste kits, connects the sink to the drain and includes traps and any bowl-to-bowl branching, while flexible braid hose packs (Insignia) are supply hoses that connect your mixer or valves to the water supply. Use a waste kit whenever you need to route waste water from the bowl to the soil pipe, and use braided hoses when you need flexible supply runs of defined lengths such as 800mm, 600mm or 150mm. you'd fit a hansgrohe single bowl waste kit to a single-bowl sink and an Insignia 800mm hose from the stopcock to a tall kitchen mixer.

A pipe shroud, such as the Architeckt Pipe Shrouds for Freestanding Bath Shower Mixer, conceals the supply pipes where they meet the floor or bath, giving a neater, finished look and protecting the pipework from scuffs. If you have a freestanding mixer standing on the bathroom floor, the shroud hides the gap and any joins, so the installation looks intentionally designed rather than exposed. It's particularly helpful in contemporary bathrooms where clean lines and visible chrome finishes matter.

Measure the straight-line distance from the valve or stopcock to the connection point on the mixer, then allow a little slack for movement and access. Insignia packs are offered in common lengths such as 800mm, 600mm and a short 150mm, so an under-sink mixer with the valve directly beneath might use 150mm, while a tall deck-mounted tap with the valve set back could need 800mm. If you're replacing an existing hose, matching the original length is a simple and reliable approach.

Branded kits from hansgrohe often match the manufacturer's fittings and finishes and can offer a reassuring fit and finish if you're using hansgrohe taps or sinks, which is why they sit at a higher price point. Sauber kits are competitively priced and designed to suit standard 1, 1.5 and 2 bowl sinks, making them a sensible, cost-effective option for many replacements or installations. If you want exact brand compatibility and a polished match with premium taps, a hansgrohe kit makes sense; for reliable everyday performance and value, a Sauber kit is perfectly suitable.
