Sinks: materials, bowls and what comes with them
Published · Updated
A sink is a fixed bowl with a waste outlet, set into a counter or hung on a wall. Makers such as Franke and Blanco build their ranges on three materials: stainless steel, granite composite and ceramic. Franke describes its Fragranite composite as quartz with acrylic resin, resistant to heat up to 280°C.

Sinks by room
The word sink covers two different products. In the kitchen, the sink is a deep bowl, often with a drainer, set into a worktop; in the bathroom, the smaller bowl for washing hands is usually called a wash basin. This page deals with what both share — materials, bowls and fittings. For bathroom bowls in detail, see wash basins; for kitchen models and what they cost, see the kitchen sink prices.
Sink materials
| Material | What it is, according to the maker | Stated properties |
|---|---|---|
| Stainless steel | chrome-nickel steel (Franke) | resistant to rust, corrosion and staining (Franke); colour-neutral, shows scratches as part of its look (Blanco) |
| Granite composite | natural quartz and acrylic resin, sold as Fragranite (Franke); a mixture with a high proportion of granite, sold as Silgranit (Blanco) | resistant to scratches, stains, chips and heat up to 280°C (Franke); dirt stays on the surface and cannot penetrate (Blanco) |
| Ceramic | fireclay fired at very high temperature (Franke); clay with other materials and a sealed surface (Blanco) | resistant to heat, stains, impact and household chemicals; smooth, non-porous surface (Franke) |

Blanco adds a point on finish: matt stainless steel is untreated, so limescale settles on it more easily than on a polished one. The 280°C figure is Franke’s own statement for Fragranite; neither maker gives a heat figure for its stainless steel.
Bowls, drainers and sizes
You choose by outer size, the number of bowls and whether there is a drainer. The models on our kitchen sink price list, checked on 12 November 2026, run from a 420 mm round single bowl to 1200 × 480 mm double-bowl sinks with a single drainer. A modern sink may also be designed for one mounting method only: Blanco offers its Subline 500-U line for undermount installation, below the worktop, and says each one must fit straight and tight in its place.
What comes with a new sink
A quoted price does not always cover the same parts. Listings on the same price page show some stainless steel models sold with waste and bottle trap but without a tap, and others sold with waste fittings, waste pipes and a tap. Ask for the tap, the waste, the overflow and the trap by name before you compare two quotes.
The wall and floor around a sink
Water splashes behind and below a sink. Kitovu has K11 Polymer Cement Waterproof Coating (Two-Component) in stock in Zanzibar; its data sheet lists kitchens, toilets and bathrooms among the areas it waterproofs, and it can be tiled over.
What to check when you buy a sink
- Material and finish — polished or matt stainless steel, composite colour, ceramic glaze.
- Outer size and bowl depth, against the cabinet or worktop opening.
- Number of bowls and the drainer side, left or right.
- Mounting — set on top of the worktop or under it.
- What is included — tap, waste, overflow, trap.
