Kitchen Sink Spares

Measure the vertical gap between the sink rim and the top of your worktop or the recess where the strap will sit; thinner 4mm straps suit shallow gaps and slim rim profiles, while 8mm and 10mm straps are better for deeper recesses or thicker rims. The site offers Sauber sealing straps in 4mm, 8mm (3m) and 10mm (4m), so match the strap thickness to that measured gap for a watertight seal. If your rim sits nearly flush with the countertop a 4mm strap usually works; if there's a clear step or thicker upstand, choose 8mm or 10mm.

Work out the total distance around the sink rim where the strap will sit and add about 10 to 20 percent for overlap and any curling. For many single-bowl inset sinks the perimeter is often under 3 metres so the Sauber 3m (8mm) option can be enough, whereas larger or double-bowl sinks commonly need 4 metres, meaning the Sauber 4m (4mm or 10mm) options are safer. Buying one 4m roll is a straightforward choice if you're unsure.

Top mount fixings (for example the Sauber Spare Top Mount Fixings – 10 Pack) are designed specifically to secure drop-in or top-mount sinks to the worktop edge. Mounting hooks (Sauber pack of 16) are versatile clamps that give extra grip where you need a stronger hold, especially useful with thinner worktops or heavy sinks. Sink clips (such as Sauber Spare Sink Clips for Sauber Inset Kitchen Sinks) are often bespoke to an inset model and give a neat, low-profile connection for that specific sink brand.

Smaller single-bowl sinks often need around six to eight fixings, while larger single or double-bowl sinks can require 10 to 16 to ensure even pressure and a watertight seal. The site lists a 10-pack of top mount fixings and a 16-pack of mounting hooks, so choose the pack that matches or slightly exceeds the number of fixings used on your current sink. If you have a Sauber inset sink, check how many original clips are fitted and replace with the same number of spare clips.

Many sealing straps, mounting hooks and top mount fixings are broadly compatible with a variety of sink types because they perform standard sealing and clamping roles, and the product notes highlight general compatibility and durability. However, some items are brand-specific, for example the Sauber Spare Sink Clips are made for Sauber inset sinks, so you should match those to Sauber models. When in doubt, compare the shape and fixing method of your existing clip or hook to the spare so you get the correct fit.
