Carpet vs. Laminate Flooring. When looking at flooring options, carpets and laminate floors are popular choices. Their cost is usually comparable and is cheaper than solid hardwood flooring. Roughly half of new flooring sold in America every year is carpet. Laminate flooring is considered more hygienic and hypoallergenic than carpet, as it is easily cleaned, and dirt won't go unnoticed.
Laminate flooring does not trap any water or dirt, and so it is easier to wipe using a brush or a sponge. On the other hand, it takes a long time, and also other cleaning products, to clean hardwood flooring. When walking on hardwood flooring, there is a natural feeling, and also the grip is firmer. On the contrary, laminate flooring gives a smoother feeling. When comparing the price, laminate flooring is cheaper than hardwood flooring.
