Bathroom floor tiles are cool in warm climates but in places where it can be really cold, they can be quite unpopular. However, now there are warming systems available so the problem of cold tiles can now be solved.
Different Types
Floor tiles are graded from 1 to 5. Bathroom tiles are normally grade 1 or 2; with 2 meaning it costs less than the top quality grade 1. Wall tiles are grade 3. Although a bit more expensive, it is advisable to use only impervious and vitreous tiles for the bathrooms.
As they are easy to clean, safe underfoot (no slip), highly durable, and highly resistant to damp, the ceramic floor tiles are the most popular choice. They are readily available almost all the time, and with a wide array of color and size selections that you can choose from.

Porcelain floor tiles are also stain and water resistant, as well as easy to maintain.
Wood laminates may be durable and decorative but it is not highly recommended for bathrooms. Even though they are laminates, there is wood underneath it and therefore not water resistant. They easily absorb moisture like real wood, and when they do, they warp.
Stone tiles like marble and slate are well treated through pressure and heat. Water resistant and therefore mold and mildew are controlled, whereas allergens and pathogens are prevented from growing on its surface.
Granite tiles is easy to care for as well and highly durable. However for bathroom floors, granite must be honed properly in order that it prevents from being slippery. They come in big slabs although they can be had in 4×4 inch tiles as well, they can be a bit costlier.
