The question more is the depth. Most brick is several inches high. If you are doing a modern bathroom floor, the recommendation is for an uncoupling layer like Ditra, then a 3/8"-thick porcelain tile on top of that. Porcelanosa has a 40% off sitewide sale right now. We just ordered some for our kitchen during their fall sale last year, and it's a quality product from a Spain-based company. They have some industrial-look styles. Happy Floors is another great company that produces in Spain and Italy and has some styles that might simulate a brick look for you.

I was going to use a brick face. It’s from Lowe’s and it’s beautiful real brink slices

Can it be done? Yes. Provided the material is rated for floors.

Is it extremely porous? Yes. Contact manufacturer for recommended sealer.

Your home. Your choice.

I've done many things over the years at the clients request. Had to look for a while to find this one.

How will you mop that? How comfortable for bare feet will that be? What will happen around the base of the toilet-yuck.

There is 3 different styles of stone in one room. Too busy. But the customer is always right

Yes Dave. It was a interesting project. Lakefront basement bath.

Think of the worst stinking gas station toilet that you ever smelt. Now imagine that brick around your toilet holding that smell saturating the whole brick and never to be exorcised. And you replacing it in short order with something that doesn’t have mop string lint, and that isn’t soaked in pee, and blood from cut feet.

Just go straight to whatever the choice to replace it would be. One home design trend that will result from this pandemic is easy to clean and sanitize surfaces. No more silly over the top temples to a marketer’s advertisement of bathing that never get used. Be ahead of that trend.

Brick is like a sponge. It has MILLIONS of holes in it. Even when sealed it will grab every single bit of dirt and debris (ahem...toilette 'splashes'). Imagine someone gets sick on the floor...how do you clean that up? You will mop and mop and mop and mop and NEVER get it 'clean'. You will cry. You will become anxious about what is growing there (not to mention the smell of 'sick').

The only way to get a brick floor (facing or not) clean is to remove the brick. Yep. Pay all that money to get it in there and then a few years later you pay all that money to get it out.

If you like the LOOK of brick, then purchase a porcelain tile with a brick appearance. It will do everything you want without all that horrible side effects

Very popular in Jamaica — be sure to wear shower sandals

Thin brick is usually intended for walls. A better choice might be 4x8 quarry tile.

Brick is just hard carpet in your bathroom.
