Above Counter vs Undermount vs Semi-Recessed Basins: How to Choose

Yes, on both counts. Cabinet depth follows the basin type as described above, and cost varies because undermount installation typically adds a fabrication and fixing cost on top of the basin itself, since it has to be bonded to the specific benchtop. Above counter and semi-recessed basins are usually simpler and cheaper to install, since they sit on or into a standard cabinet without needing that bonded fit.

• Undermount adds the highest installation cost of the three, largely from the stone or solid-surface fabrication needed to seat the basin correctly.
• Above counter and semi-recessed basins install onto a standard cabinet top without specialist fabrication, keeping installation cost lower.

Trade tip: get the benchtop fabricator’s quote before locking in an undermount basin choice, since the fabrication cost varies more between suppliers than the basin price itself.
