How do I choose the right waste kit for my sink — single, 1.5 or double bowl?

Match the kit to the number of bowls you have — there are dedicated pipe kits for 1 bowl, 1.5 bowl and 2 bowl sinks (for example Sauber offers each of those). Also check whether the kit is described as suitable for 1.5 or 2 bowls, such as the Wirquin Espace which covers both. If you have a 1.5 bowl stainless sink used mainly for rinsing and prep, the Sauber 1.5 bowl pipe kit is a straightforward choice; for an actual double sink, opt for a double-bowl kit like Sauber's or one of the Hansgrohe double-bowl options.

What is a space-saving syphon and when should I pick the Reginox Panama?

A space-saving syphon is shaped to take up less cupboard space beneath the sink, so you can fit bins or appliances more easily; the Reginox Panama is explicitly marketed as a space-saving waste syphon. Choose it when you have tight under-sink clearance or need to route plumbing around an appliance. The trade-off is a slightly higher price (the Panama is listed around £35.99) compared with simple pipe kits, but you gain valuable storage space beneath the sink.

Do ceramic sinks need a special basket strainer size?

Yes — ceramic sinks often use a larger, visible strainer designed for the sink's waste hole; the Rangemaster Basket Strainer Waste Kit is specified at 89mm for ceramic kitchen sinks. Measure the diameter of your sink's waste hole and match it to that 89mm size where listed. For example, a ceramic Belfast or farmhouse-style sink frequently uses an 89mm strainer rather than the smaller metal inserts used in many stainless bowls.

How much will a kitchen sink waste kit usually cost and what influences the price?

Prices on the range span roughly from mid-teens to around £45; for instance, the Wirquin Espace appears from about £16.52, Sauber pipe kits sit around £24.99–29.99, Reginox Panama about £35.99 and Hansgrohe branded kits nearer £42–45. Lower-cost kits supply the basic pipework and connections for a standard sink, while branded items or specialised parts like space-saving syphons and ceramic basket strainers tend to cost more because of design or brand engineering.

Can one kit cover different sink layouts or do I need separate parts for each bowl?

Some kits are specific to a layout, such as distinct Sauber pipe kits for 1, 1.5 and 2 bowls, while others are more flexible — the Wirquin Espace, for example, is listed for 1.5 or 2 bowl sinks. If your sink is a true double bowl you should use a double-bowl kit or a kit explicitly rated for two bowls; for a 1.5 bowl sink you can choose either a dedicated 1.5 kit or a flexible option like the Espace range. Choosing the matching configuration avoids awkward joins and simplifies connection to your existing waste outlet.
