As the name implies, drop-on sinks are merely sinks that are ‘dropped’ onto a countertop, which has been cut to size beforehand. One way to differentiate this kind of sink installation from the rest is by noticing how the sink rim is placed above the countertop rather than below. This sink installation technique is very popular as the method requires little effort and is uncomplicated.

 If you’ve just purchased a brand new Franke sink and haven’t given much thought to its installation, it may be a good idea to think about using the drop-on sink installation method as a way to avoid a labor-intensive endeavor.

We’ve prepared a step-by-step guide to help you with your drop-on sink installation:

Before you begin, you will need the following:

  • Pencil
  • Jigsaw
  • Torch
  • G-Clamps
  • Tape Measure
  • Silicone Sealant
  • Drill with 9mm or larger bit
  • Nut Driver - 9mm
  • Screwdriver with 152mm shank

Step One

If you’d like to mount your mixer on top of your sink, you’ll have to trim the inside of the carcass, using your jigsaw, to allow for tap hole installation.

Step Two

Ensure ease of installation by trimming cleat with jigsaw.


Step Three

Position cut-to-size cleats on the inside edge of the sink apron. Using cleats will ensure effortless sink installation onto the cupboard.


Step Four

Now position your sink onto your cupboard top.


Step Five

Once you’ve positioned your sink, you will need to fix it in place with screws. Attach your screws through the edge of your cupboard and onto the cleats.


Now that your sink is rigidly fixed in place, it’s time to take a step back and appreciate the result of all your effort! We hope that you’ve found this step-by-step sink installation guide useful, and that you’re now enjoying the benefits of your shiny new drop-on sink.
