In regards to considerations, suggest searching on line for all of the advantages/disadvantages, as it’s a big decision.

Brick floors are great. The care should include sweeping, vacuuming or dry moping followed by cleaning with vinegar and water solution. Applying a water repellant wax periodically is also a good idea.

Brick and mortar floors have to be rinsed and dried with towels after washing to prevent the mortar from accumulating grimy soapy water. If the grimy soapy water builds up anyway, you can scrub the mortar with a brush. There are machines you can buy to scrub and then suction up most of the dirty water. Rinse with clean water and repeat. Every once in a while, you can get the bricks professionally cleaned and sealed. I would never, ever install a brick floor.

Think "Cinderella". As apple_pie_order suggest, they are a lot of work. If you REALLY want the look of brick but you do NOT want to become a slave to the floors, you can look at brick-look porcelain tile. The higher priced one's are very realistic.
