I would not use it at all.

No to that specific mosaic, which will date your bathroom to 15 years ago!

If that 12 x 24 tile has actual ridges, I don't think I would use it in a rental, where a tenant might not be as diligent about keeping things clean. The easiest to maintain would be a polished porcelain.

I would also skip the accent tile completely. Keep the look clean and simple and timeless and versatile - I think you'll be happy that you did.

It's so easy to add color and interest in other ways (i.e. towels and artwork and rugs) that are easy to change when needed.

A tenant, specially female, might also not feel comfortable with a clear window in the shower, so I would install some opaque window film before I listed it for rent.

The tile has lines but not grooves - but has traction as it's matte finish - so cleaning should be ok. Yes, window is frosted - in the picture the window was slid open. Thanks!

I'm sorry to also rain on your parade but that tile with the lines looks dirty to me and the mosaic doesn't work with it at all. I like the idea of using larger tile, fewer grout lines to keep clean.

Won't use mosaic....don't want to date it to 15yesr back!! :) thanks for the input.

Using 12"x24" tile instead of the 1" square mosaic on the shower floor, so less grout. Looked at bigger tile but it being a small space they could not slope it properly to make it truly curbless - as big tiles in a small space cannot be manipulated as easily and that would give a tiny lip at the shower door - which we do not want.

The floor needs the smaller tiles so people don’t slip. Don’t use the big tiles there. Find a small hexagon, penny tiles or use the 1” squares (post what they look like).

The grout creates helpful friction. I am a no on the first mosaic look so I’m hoping that isn’t what you are referring to when you say 1” square tiles.

And… as you plan out the wall niche, try and line it up with the grout lines in the shower tile so that there are fewer cuts into all of the tiles that surround it.

The large format tile is nice but absolutely not that mosaic.

By 1" - I did not mean the picture I posted - its the standard 1" or 2" tiny squares that come in a sheet of 12"x12".

The 12"X24" I posted has friction enough for not slipping according to the tile shop as they could have sold me the tiny 1"-2" piece pasted in a 12"x12" square sheet.

The niche cannot go wider due to structural framing behind - but can do a 12" wide one so it lines up with the 12"x24" tile.

I did a small bathroom a few years ago with 21" x 21" inch tile including on the ceiling. I made the mistake of incorporating two different tiles that I loved into the design. They work OK with my bathroom, but sometimes, keeping it all the same is your friend. And YES, you can use large tile in a small bathroom. I agonized hugely over that based on crap that I read on the internet, and it looks great.

If your shower were larger, then I would totally agree with the commenter that said to do 1" x 1" (small tile) on the floor so that no one slips. Yours looks to be on the edge sizewise.

What I can tell you, is that getting those grout lines to hit exactly as clean as in your drawing is not for DIYers--particularly if you want small grout lines.

Your design, of course, but as a suggestion, how about cutting the mosaic into strips and running the strips horizontally from the niche across the shower (that is, niche is done in mosaic and then a 2" mosaic strip radiates outward from the niche).

I don't know anything about that particular mosaic, but I would ask at the tile store whether it was suitable for a shower area. Some stones absorb water, and there might be paper backing behind the glass strips to give them color. Would that tile be better in an area that was not exposed to water? I truly no nothing about this, but it is just something that occurred to me, so I could be all wet (pun intended) about being concerned about it.

Have you purchased the ridged tile yet..if not skip it. It's too design specific and will be dated the minute it's installed.

The best solution is to find a tile color or pattern that is manufactured across different sizes. Then use the 12x24 size, and the mosaic size for the shower floor. Definitely a mosaic for the shower floor...with a linear drain especially. Penny or 1 inch is a llitle busy...look at a 2 inch hex or 1x4 rectangle, something like that.

The tile person said that 12x24 they can handle - not bigger as the bathroom is small. Yes no mosaic!! (I thought some one would say ok to using it in the niche - but I guess it's a BIG no to the mosaic!!) Thank you!

Also make sure you can do a niche on the exterior wall. You may need to relocate that.

The tile choice is moot at this point. Nothing about that curbless shower is done correctly. Not the waterproofing tie in, nor the drain location, nor a capillary break. Zilch. That is future water damage right there. And a slip and fall hazard both.

If you need room for more shower items, consider a ledge instead of struggling to get the niche in the right place.

Or a shower basket. I used these from Kartners. They come in different sizes and finishes.

The ledge is a great idea but the shower area is only 30" wide so will eat into the real-estate and might hit your elbows - just thinking out loud.....maybe I should put it on the 30" wall instead of the 60" wall.....I will also have to look into a granite or porcelain piece for them to install like this.....Thanks for the idea!

@DeWayne The inspector came and inspected so I'm hoping they are doing it ok!!! I have no idea if they are not waterproofing it correctly!!

If you posted more photos some people on here are sure to know.

We/contractor did a central drain initially and the city made us redo for a linear drain (new rules) and they told us exactly where the linear drain should be!! Then they contractor sent his guy to do all the waterproofing stuff and then the city inspector came back to sign off......so.....the tile guys can start their install....

These are the pictures I have from the current site....I can ask the contractor about extending the waterproofing some more into the room, but right now it does extend at the bottom on both sides - let me post some pictures
