Under Counter Basin

1. Countertop Cut-Out

• Ensure the countertop cut-out matches the basin size.
• The cut-out should be slightly smaller than the basin rim so it doesn’t show from above.
• Smooth and seal the edges of the cut-out (especially for stone/granite).

2. Mark & Prepare Mounting

• Turn the countertop upside down or access from underneath.
• Mark the centre of the cut-out and place the basin aligned properly.
• Clean the edge of the cut-out and basin rim with a dry cloth.

3. Apply Sealant or Adhesive

• Apply a continuous bead of silicone sealant or epoxy adhesive around the basin rim.
• Carefully place the basin against the underside of the countertop.

4. Fix the Basin

• Clamp the basin to the countertop using temporary supports (wood blocks, basin clamps, or metal brackets).
• Allow the adhesive/sealant to cure for 6–12 hours (follow product instructions).

5. Install Waste Outlet

• Fix the waste coupling into the basin’s drain hole using PTFE tape.
• Attach the bottle trap or P-trap and connect it to the wall drain.

6. Connect Water Supply

• Install angle valves at water inlets.
• Connect flexible hoses from valves to the faucet above the counter.

7. Finishing & Testing

• Once cured, remove clamps and clean excess sealant.
• Turn on the water supply.
• Check all joints for leakage.
• Clean the countertop and basin for a smooth finish.
