Walk-in shower with floor-to-ceiling tiles

Hi everyone,
for our house which we will receive in March
we are currently choosing tiles.
I have attached the bathroom floor plan.
We want as few joints as possible at least in the walk-in shower,
we are thinking of using the huge porcelain stoneware
tiles you see in tile specialty stores at least for the 3 sides in the shower area as well as on the floor.
Are there any advantages or disadvantages to this, can the tiler manage this without charging us a small fortune as extra effort? And what do you think of the idea in general?

Thanks already for the feedback.

Of course, it will be significantly more expensive to install such a tile (if you can even still call these huge things tiles). At the moment, you see this everywhere in showrooms just as it is with the currently trendy, expensive fashion trend. You speak of a "wish," and therefore you should know exactly why this should make your bathroom more beautiful or whether I should rather fulfill another "wish" during the house construction instead. The bathroom does not necessarily become more beautiful because of this; it depends more on the overall design than on the size of the tiles.

You need people who are familiar with this for it. The "normal" tile installer is usually not a professional. They might still be able to lay 60x60 tiles, but that's the upper limit.

And yes, it will be significantly more expensive. But there are also users who have implemented this themselves.

Flooring can also be very slippery when wet in large formats, therefore consider mosaic format as flooring

We would have also liked to use such large tiles. Why we decided against it: - Our shower is 140cm long, but the tile was only 120cm wide - No tiler will guarantee that the tile won't break during processing, so you should plan for replacements (But how many? Each tile costs a small fortune and afterwards you can't do anything with it.) - You first have to find a tiler who can do it and does it well - Even the delivery alone is very expensive Conclusion: We chose 120x120cm tiles, which also results in hardly any grout lines.

I don't even find the very large tiles beautiful. Normal bathrooms are too small for them. But I actually prefer smaller tiles, larger than [Mozaik] (I'm a bit annoyed by [Mozaik]. I've grown tired of it), but smaller than 20x20. In my opinion, that looks more interesting than the plain large and gray common things.
