How much does a custom concrete sink basin cost installed in a Vancouver bathroom?

A custom concrete sink basin in Metro Vancouver typically costs $1,500–$4,500 installed, depending on the size, complexity of the casting, edge profile, integral drain design, and whether the piece is fabricated locally or sourced from an artisan studio.

The concrete itself is relatively inexpensive as a raw material — what you're paying for is skilled fabrication. A local concrete artisan will design a form, mix a fibre-reinforced concrete blend (often with glass fibre reinforcement or GFRC — glass fibre reinforced concrete), cast and cure the piece over 7–14 days, grind and polish the surface, and apply a penetrating sealer. Simple vessel sinks on the smaller end of the size range sit closer to $800–$1,500 for the basin alone. Larger undermount or integrated vanity-top-with-sink pieces — where the countertop and basin are cast as one unit — run $2,000–$5,000+ for the fabricated piece before installation.

Installation adds $300–$800 in plumbing labour, covering the drain assembly, P-trap connection, supply line hookup, and faucet installation. If the concrete piece is an integrated countertop-and-sink, a plumber and possibly a countertop installer will both be involved, and the weight of the piece (concrete is heavy — a 48-inch integrated top can weigh 80–120 lbs) means the vanity cabinet must be structurally sound and properly secured to the wall with blocking. In Metro Vancouver's Seismic Zone 4, wall-mounted vanities supporting heavy concrete tops require fastening into solid blocking or structural framing — not just drywall anchors.

Sealing is the most critical maintenance consideration for concrete sinks in Vancouver's humid climate. Concrete is naturally porous, and without proper sealing, it will absorb water, soap, and toothpaste, leading to staining and — in a bathroom with inadequate ventilation — surface mould. A quality penetrating sealer (such as Cheng Concrete Sealer or a food-safe epoxy topcoat) applied at fabrication and reapplied every 1–3 years is essential. Make sure your fabricator specifies exactly what sealer they use and what the resealing schedule looks like before you commit.

Ventilation matters more than most homeowners expect with a concrete sink. Because concrete can harbour surface moisture if the bathroom doesn't dry out properly after use, an exhaust fan rated at minimum 80 CFM ducted to the exterior is important. Vancouver's ambient outdoor humidity of 75–85% means a bathroom that doesn't ventilate mechanically will stay damp, and a porous concrete surface is one of the first places you'll see the consequences.

Practical tips before you buy:

Ask the fabricator for a sample tile or puck of the finished concrete so you can see the actual colour, texture, and sealer finish in your bathroom's lighting — photos rarely capture it accurately. Confirm the piece is GFRC or fibre-reinforced rather than standard cast concrete, as this significantly improves crack resistance. Get the weight spec in writing so your plumber and installer can plan the vanity support accordingly. And budget for a faucet with a longer spout reach — concrete vessel sinks in particular often need a taller or longer-reach faucet to avoid water splashing off the basin edge.

A licensed plumber must handle all drain and supply connections — this is not a DIY installation given the weight of the piece and the plumbing code requirements in BC.
