What is the tile? Link it or post pictures please as people are not going to search for it for you. What is the COF (slipperyness)? Does the mfr rate it or allow it for shower floors?

Sorry. Here is just one link, and it is labeled for floor or wall, but another product had comments by people saying they could not imagine it for the floor, and no pictures uploaded had people using it for the floor. But again, that was not for this particular product:

http://www.homedepot.com/p/Merola-Tile-Arabesque-Glossy-White-9-7-8-in-x-11-1-8-in-x-6-mm-Porcelain-Mosaic-Floor-and-Wall-Tile-FDXARGW/203886325

Is that correct that it is 10x11 inches? They show it on a backsplash. It doesn't look near that size.

There is a size constraint for shower floors due to the need to slope them although I don't know what the max size tile would be. I would think this is too large for that application.

There's also the slip factor. Glossy tiles are very slippery even without adding water to the mix. It doesn't take much to slip on a smooth tile when there is some water involved. Textured offers some tooth or grip. There should be a rating. Tiles rated for commercial use are the least slippery.

It says " 11.125 in. length x 9.875 in. width x 6 mm thick mesh-mounted mosaic. 1.87 in. W x 2.75 in. length brick pieces". So 11 x 10 would be the mesh mounted area I think. Says the friction rating is greater than 0.50 and says it's grade 1 tile.

I see, did not notice that.

Grade 1: This is the weakest of all standard grade ceramic tiles. It’s really only suitable as a wall tile.

Grade 2: This is best for light traffic areas. Again, a great product for wall tiles, but it will also work in residential bathrooms, where foot traffic is minimal.

Grade 3: Where ceramic tile ratings are concerned, grade three is most common in residential building, and perfect for light to moderate traffic. This makes it a very sensible choice for residential kitchens, countertops, residential flooring, and all areas that receive lighter wear and tear (i.e., grade 1 and 2 areas).

Grade 4: This grade is a step up from grade 3 tile grades. It’s still a good choice for residential uses, such as tile floors and countertops, but it can also take the heavier abuse of light commercial foot traffic, such as you’d find in a doctor’s office.

Grade 5: This stuff is as tough as it gets. When it comes to standard grade ceramic tiles, grade 5 is built to take a beating. It’s mostly used in high traffic commercial areas such as shopping malls and airports.
