What are the most hygienic worktop materials?

You might not wonder this often, but when looking for your new countertops you might want to consider how to material you choose affects your ability to keep it clean. Surfaces that are prone to germs and bacteria are not ideal, especially when you are dealing with food preparation.

According to recent studies, porosity is the main element that leads to bacteria and health issues. Non porous surfaces are less susceptible to germs, offering greater protection against these organisms. 

We have gathered a collection of worst and best materials in terms of cleanliness. Compare the existing array of worktops and determine the most suitable for your home. 

Steel, quartz and granite worktops are the most hygienic

Granite worktop


Stainless steel is a common choice for professional chefs. The single sheet materials has an excellent antibacterial surface, with properties that repel all sorts of germs, that appeals to the commercial market.

This countertop surface has long lasting durability and requires very little maintenance so upkeep is minimal. An antibacterial wipe clean will keep the surface clean and clear. The one downside is that it is significantly more expensive than other materials meaning it won’t be the first choice for most homeowners..


Granite is formed by millions of years of compressed molten rock fusing together. Because of this Granite worktops offer a nearly impenetrable shield against germs, as long as they are properly polished and sealed.

Even though granite is a porous material, applying a surface sealer once or twice a year keeps it in perfect shape.


Quartz worktops, on the other hand, need almost no maintenance. Thanks to their non-porous composition, they are the most reliable alternative. As there is no absorption of dirt or filth, quartz worktops won’t foster bacteria or transfer them onto foods or objects.

Wood, Laminate and Tile are more susceptible to lingering germs



Wood is a natural product that is affected by heat and humidity. It expands when the humidity is high and contracts when it’s low. Wood surfaces are extremely susceptible to bacteria due to their high porosity. They are also very difficult to maintain.

There is no proven highly effective formula to disinfect wooden worktops and get rid of all the bacteria. Countertops of this kind need to be regularly cleaned and varinshed – to keep it protected from warping.to avoid any health issues.


Laminate it’s a low cost option that comes with a variety of colours. However, the affordability is balanced by it being it has much less durability when compared with other materials. The surface also has very low resistance to high temperatures and scraping. After some time the layers wear down and become more porous, attracting germs and viruses.


Tile countertops are very popular due to their high resistance to heat and easy maintenance. But they do come with a few problems regarding hygiene.

Grout, the construction material used to seal joints in between tiles,  collects food particles and is extremely difficult to clean. Its porous structure makes it a breeding ground for bacteria. As well as the buildup of moisture and dirt.


Though wood may look great and steel is the most hygienic, quartz and granite worktops are both trustworthy materials of the highest quality that offer both benefits. The surfaces provide safe germ-free environments, a benefit for kitchen and bathroom areas.
