How to install a Sink: 3 types of installation

Published on February 13, 2023

The sink, one of the main organs of any self-respecting kitchen. As important as it is complex to find with all the features we want.

Type, size, colour and method of installation are just some of the parameters that must always be evaluated before purchase. Some purely design-related, others purely technical.

Today we will discuss methods of installing a sink, looking at the three most common types today.

Standard Installation (flush-mounted)

Standard Installation 2

As can be guessed from the words 'built-in', this type of installation requires the sink to be lowered into a hole in the kitchen worktop and then placed, via its edges, on the latter.

Once the sink is in position and level, it is fastened by means of screws that are clamped onto mounting brackets immediately below the edges of the sink.

However, before the final fixing, a layer of silicone is placed between the sink and the kitchen top, which has a dual function. The first is to help secure the sink to the countertop, the second is to prevent water from seeping underneath the kitchen countertop.

Subtop installation

Subtop installation is the reverse of standard installation. The sink is not lowered into the hole of the cooktop, but is placed underneath it.

In this case, the fixing method is practically mechanical, as the sink is blocked by both the weight of the kitchen surface and the silicon that is always inserted between the sink and the kitchen surface

There are three variants of this type of installation:

  • Variant 1The edges of the sink and the cooktop match perfectly;
  • Variant 2: the kitchen top extends beyond the edge of the sink, covering its edges;
  • Variant 3The edge of the sink remains visible, creating a kind of step.

Integrated Installation

The latter type of installation is one of the most complex and requires the most work prior to assembly.

First of all, this installation method can only be carried out when the sink and hob are perfectly compatible with each other.

Secondly, as already mentioned, this type of embedding must be carried out in a workmanlike manner due to the small margin of error of the components.

To summarise the procedure to the bone, the sink is lowered into the kitchen countertop which, prior to installation, has been modified so that its edge presents a 15-degree angle to accommodate the sink, creating a semi-recessed area that will be made stable and waterproof with a silicone-based sealant.


The sinks in our catalogue offer these types of installation, depending on the model. Of course, some sinks are only compatible with some, but these are indicated in advance in the product sheet.
