Take a look at Emser tile. It makes lots of styles suitable for shower floors, many of which are available 2 x 2. It also has showrooms around the country where you can look at its products -- and from which you can take samples home -- some of which can be purchased at Home Depot or Lowes.

Thanks everyone. Jmm1837, do they actually rate it? What's a good rating? Is it like 1 thru 10?

Avanti Stone and Tile, can you share what you and your clients like for porcelain 2x2 or smaller? It's a square-ish small shower with regular drain.

Is terra cotta too soft and porous? I really like the Cle terra cotta tile, the Zellige line.

DalTile has many choices....however HD or Lowes offers decent 12x12" sheets of mosiac tiles that have a decent texture to them. Any of these will suffice.....

HU-870157674: There are anti-slip ratings as described in the Wikipedia article Floor slip resistance testing of which the ANSI/NFSI B101.3 wet dynamic test method would appear most useful for showers. However, manufacturers frequently don't provide these data. (This Marazzi Block tile does (DCOF minimum 0.42)). I think you really have to rely on manufacturers' statements of the applicability of a tile for use as a shower floor rather than the DCOF to avoid rejecting many suitable tiles from contention.

I did a classic basket weave tile on my shower and bathroom floors.

The grout makes them completely non-slippery as opposed to the larger tiles which were like ice if my feet were even damp.

Mine are marble but any small tiles would have the same grip pines.

Thanks everyone. I think safety and accommodating a sloping shower bed are foremost. There are so many choices and I can't really picture when it will look like. Helen, I have a friend who has a basket weave with porcelain, a white carrara look but not marble. It's beautiful!

I did a 3" hex in my shower and it's 8' long. you can go up to 4" without issue.

for my neighbors I did this gray porcelain in an elongated hex. it also has a matte finish. very easy to care for.

there area thousand diff places to buy decent porcelain tile. Italian porcelain will be your better quality. the difference in ceramic and porcelain is w/the latter the color goes all the way down. if you crack or chip a tile, you won't see the white/gray base like you will on ceramic.

this is a porcelain basketweave tile to resemble the marble look. home depot has it or look online at other sellers. comes in diff color 'dots' too

these would be perfect for a shower floor

Thanks BethH, those look really nice. I had heard Italian tile was nice and I know lead is banned there so I'd love to find something made in Italy.

Hi everyone, I really love this marble look here in this photo. This is what I want on shower floor but I don't want marble due to maintenance. Can anyone recommend a porcelain that looks like this? Thanks! Even if they're 2x2 that's ok too. I think these here are 1x1.

Daltile is very good at marking their boxes with the slippery factors. They call it either WCOF or COFW. The COF stands for coefficient of friction, so using the letters is good. There is also a dry COF which is indicated with DCOF or COFD. The numbers go from 0 to 1 with numbers above 0.5 being much better. You cannot simply look at a tile guess the friction coefficient. The tile we picked looks a little shiny but has a well deserved WCOF of .7.

I found the following statement on the Home Depot website for a specific tile.

DCOF greater than or equal to 0.42 slip-resistance meets requirements
for use on dry, or wet, level floors, not recommended for shower floors
due to tile size, all products manufactured by Daltile meet or exceed
the requirements of the ANSI standard

That is misleading at the very least. The DCOF is meaningless for wet surfaces. Look for the WCOF.

Thank you dchall. The thing is though there are no boxes at the showrooms. Just boards that the sample tiles are glued to. But thanks for the great info. Maybe I can find where that's listed for tiles I'm considering.
