A stone sink is heavy, and the wall decides how it is installed. Read this page, then give the one-page guide to your installer.
What you need
- A level, a tape measure and a pencil.
- A drill, with a masonry bit if the wall is masonry.
- Fasteners for the wall: lag screws for studs, masonry anchors for brick, block or concrete.
- Neutral-cure silicone sealant. Acidic-cure silicone can stain stone.
- A helper. Plan for two people to lift the basin onto the bracket.
- A faucet and a pop-up drain without an overflow. The drain fitting is not included.
The wall
Mount the bracket into studs or masonry. Plasterboard alone will not carry a stone sink. If the studs are not where the bracket needs to be, open the wall and add a solid timber backing board between the studs.
Bracket height
The standard height for the rim is 34 in / 865 mm from the finished floor. The bracket sits under the basin, so:
Bracket top = rim height − basin height.
With the rim at 34 in / 865 mm and a 7 in / 178 mm basin, the top of the bracket is at 27 in / 687 mm. Mark a level line at that height before you drill.
Sealant
Run a thin bead of neutral-cure silicone along the back edge where the stone meets the wall, and where the basin rests on the bracket. Wipe off any excess at once. Let it cure for 24 hours before heavy use.
How heavy is it
These are the weights of three example sizes. The product page and the specification sheet show the weight of yours.
| Size | Weight |
|---|---|
| 20 × 14 × 6 in | 41 kg / 91 lb |
| 28 × 16 × 7 in | 67 kg / 147 lb |
| 40 × 16 × 7 in | 95 kg / 210 lb |
Weights are approximate. The wall has to carry the basin, the faucet and the water in it. Never hang a basin from plasterboard.
