Seima Kitchen Sinks Buying Guide


Seima is an Australian bathroom and kitchen brand, and its kitchen sinks come in stainless steel and Arqstone, a quartz-based material, across ranges such as Tetra Pro, Kubic, Acero, Oros, Rhodes and Icaria. The collection suits everyone from apartment kitchens needing a compact single bowl to large family kitchens wanting a double with a drainer.

What is the difference between the Seima sink ranges?

  • Tetra Pro: handcrafted 304 grade stainless steel with 10mm radius corners, fitted above or under the bench. The Tetra Pro Blade double has a thin dividing wall between the bowls to cut down on splashing.
  • Kubic: 304 grade stainless steel in a silk finish, 1.0mm thick, with square lines and a sound-deadening basket waste.
  • Acero: polished 304 grade stainless steel, including Classic models with an embossed drainer.
  • Oros and Rhodes: Arqstone sinks in black or white with an integrated overflow. Seima labels the Oros range Made in Europe.
  • Icaria: a 510mm round Arqstone bowl for a bar, pantry or second prep sink.

What size Seima sink do I need?

Measure the inside of your base cabinet and allow the sink to be 70 to 80mm narrower. For a 600mm cabinet, the Kubic 500 (544 x 444mm, 40 litres) or the Oros 550 (552 x 440mm) are close fits, so check the internal width. For a 900mm cabinet, look at a 1.5 or 1.75 bowl or a double such as the Oros 820. The Kubic large single is 750 x 750mm, which suits an island bench, and the Oros 1160 and 1162 with drainers need a long benchtop run.

Should I choose stainless steel or Arqstone?

Choose stainless steel if you want a light, hard-wearing sink that suits any kitchen. The silk finish on Kubic hides fine scratches better than the polished Acero. Choose Arqstone if you want a solid black or white bowl that reads like stone. Treat Arqstone with some care: a heavy dropped pot can damage it, and white shows tea and coffee stains more readily than black.

Can Seima sinks be undermounted?

Many can. Most Tetra Pro, Kubic and Oros sinks are listed for either inset or undermount fitting, and an Acero double is available as an undermount. Undermount fitting needs a solid, waterproof benchtop such as stone. On laminate or timber, choose inset fitting, where the rim rests on the bench and covers the cut edge.

How many tap holes do Seima sinks have?

It depends on the model. Most Oros sinks have no tap hole, so the mixer mounts on the benchtop. The Oros 620 has a tap landing with 0, 1 or 3 tap hole options, the Oros 1160 and 1162 come with 0 or 1, and the Icaria has one. Match the hole count to your chosen tap before ordering, and confirm the tap position with the benchtop installer.

How do I clean a Seima sink?

Rinse after use, wash with mild dish soap and a soft cloth, then dry with a microfibre cloth to stop water spots. Wipe stainless steel along the grain. Use a pH-neutral cleaner on Arqstone, and avoid bleach, abrasive powders and steel wool on both materials.

Frequently Asked Questions

What is Seima?

Seima is an Australian bathroomware and kitchenware brand, known for design-led basins, sinks and fittings sold through plumbing and bathroom retailers nationally. Its kitchen sink range sits alongside a broader bathroom product line, so it's a brand you'll also come across when sourcing basins or accessories for the same renovation.

Where are Seima products made?

Seima designs its range in Australia, with manufacturing carried out at facilities the brand selects to meet its design and quality specifications, a common approach among established local brands that source components and manufacturing globally rather than from a single factory. What matters for a buyer is that the specific product carries valid Australian certification (WaterMark for tapware, relevant standards for sinks) regardless of where it was made.

Which sink brand is best for a bathroom-and-kitchen renovation?

There's no single best brand, it depends on bowl material, configuration and design preference. Seima is a solid option where design and finish consistency across a wider bathroom and kitchen project matters, since the brand's sink range sits alongside its basins and other fittings. If your priority is pure durability at the lowest cost, comparing gauge and material across brands is more useful than picking on name alone.

What brand of sinks are the best?

Rather than one best brand, it's more useful to match the sink material and bowl configuration to the kitchen. Seima's kitchen sinks are designed with the same attention to form as the brand's bathroom range, which suits a kitchen where matching design language across rooms is part of the brief.

Does Seima make both kitchen and laundry sinks?

Seima's core range is bathroom and kitchen focused rather than laundry-specific. If you're after a laundry sink to match a Seima-influenced kitchen aesthetic, it's worth browsing the dedicated laundry sinks range, since laundry bowls are sized and configured differently to kitchen sinks regardless of brand.

What sink materials does Seima's kitchen range use?

Seima's kitchen sinks are available in the material categories common across the Australian market, including stainless steel, chosen for its durability, hygiene and price point. As with any brand, checking bowl gauge and finish (satin rather than mirror-polished, for easier day-to-day maintenance) is a more reliable quality signal than the brand name on its own.
