The full sequence, start to finish
From a bare wall to a mounted, sealed sink — see how carriers, adhesive, and caulk come together.
The method
Mounted in three steps
Step 01
Bolt carriers to studs
Fix primary and secondary carriers to wood studs behind drywall. Primary carriers are the two outermost brackets and carry most of the load.
Primary height: 33 in (34 in rim)
Mount 1 in below top surface
PreFab 29 in · Designer 25¾ in
Step 02
Fix sink to carrier
Set the sink onto the carriers with silicone adhesive. Shim to the intended height and ensure no gap between carrier and sink.
Secondary spacing: max 32 in
Typical 24 in · minimum 18 in
Step 03
Caulk to finished wall
Seal between the sink and finished wall with a continuous silicone bead. Add the optional matching plumbing enclosure to conceal supply and waste lines.
