The installation process will vary depending on the type of work top that you have.
Most sinks come with installation guides.
However, we do recommend that you seek professional advice.
A template and fixing clips are provided to install the sink.
Some sinks may allow for fitting the bowl directly to the worktop.
If this is not the case, then a plywood template can be made to the size of the sink. This will effectively sandwich the sink flange, when addressed to the underside of the material.
We do recommend the use of a sealant between the flange of the sink and the worktop, to avoid any water ingress.
