Cement board is not waterproof so who ever is doing the work needs to waterproof the shower Post a to scale floorplan of the whole bathroom . I think the 12 x24 will work and in a small space I use those same tile on the shower walls to keep the space looking less cluttered and fewer grout lines .I dislke penny tile on shower floors but now you have them work with them but those subway tile I would return.I am wondering how you will install a toilet in that space it does not appear to be even 30" wide which is the min. for a toilet and tehn how do you get in the shower .I think you need to stop until you get this right . Who is doing the work?

I happen to like penny tile for a shower floor. Good choice but it takes skill to lay them.

Agree to asking how wide is the space for the toilet. :)

I have a general contractor and it is 30 inches by a hair for the toilet space. Inspector came by and approved the plans. This was the existing bathroom layout, except it used to be a tub/shower combo. This picture was taken before any waterproofing was done. It’s the most complete photo I had on hand at the time of posting.

What is the tile you are using for shower?

Personally, I think the tile is fine.

Just got in by a hair. LOL

is this for a tub? That large tile, it's going under the tub on this cement board?

or is this a shower floor?

I hope its not a shower floor!

That wood curb also needs to be completely covered.

Can we see how the shower is being formatted for the waterproofing?

what if you stacked the large tile on the floor? basically like this. (I think it's too large for that small space. there's going to be a lot of cuts, which is a waste for this large format tile)

any chance of doing something diff on the floor? diff tile altogether?

you're doing the plain white tile on the wall, the hex on the shower floor, and then you have the small space for the other tile?

is the shower tile going in like this? (you'll notice the square tiles on either side in the white)

you could do a larger hex tile (this is a 2") and use it for all of the floors.

you doing a niche? w/the hex tile?

I did this layout for my neighbor. used a recycled white glass tile for the niche. (it's not green)

or, do a larger, darker hex or something like this gray

I'd rather use a longer tile for the shower, like this. can you get that tile in a larger size?

you could use this tile on the outside floor in a herringbone or some other layout

even this size is better. looks like a 3x12. you could do this on the floor in a diff type of layout

I like this basketweave layout

or, try a terrazzo look 24x24 size tile for the floors

The penny tile would work for all the floors (main bathroom and shower). Stack the white vertically on the shower walls and you have a nice, simple bathroom plan.

Smaller tiles are better in a bathroom because the grout helps reduce slipperiness.
