ᐅ Walk-in shower with floor-to-ceiling tiles?

Hi everyone,
for our house, which will be delivered in March,
we are currently selecting tiles.
I’ve attached the bathroom floor plan.
We would like to have as few grout lines as possible in the walk-in shower. We’re thinking of using large-format porcelain tiles—like the big ones seen in tile specialty stores—at least on the three shower walls and the floor.
Are there any advantages or disadvantages to this? Will the tiler be able to handle this without charging us a fortune for the extra work? And what do you think of the idea in general?

Thanks in advance for your feedback.

Of course, it will be significantly more expensive to install such tiles (if you can still even call those huge slabs tiles). At the moment, you see this trend everywhere in showrooms as part of the currently popular, expensive fashion.

You’re talking about a "preference," and therefore you should know exactly why this should make your bathroom more attractive or whether you might want to fulfill a different "preference" during the house construction instead. The bathroom doesn’t 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 experienced with this. A regular tiler usually is not a specialist. They might be able to install 60x60cm (24x24 inch) tiles, but that is about the limit of their expertise.

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

Large-format flooring can be very slippery when wet, so consider using mosaic tiles for the floor.

We also wanted to use large tiles like that. Here’s why we decided against it:
- Our shower is 140cm (55 inches) long, but the tile was only 120cm (47 inches) wide
- No tiler can guarantee that the tile won’t break during cutting, so you should plan for extras (but how many? Each tile costs a small fortune, and afterward you can’t really use broken pieces)
- You first have to find a tiler who can do it well
- Even the delivery alone is quite expensive
Conclusion: We chose 120x120cm (47x47 inches) tiles instead, which also results in very few grout lines.

I don’t even find very large-format tiles attractive. For standard bathrooms, I think they are too big. I actually prefer smaller tiles—larger than mosaics (mosaics annoy me a bit; I’ve grown tired of them)—but smaller than 20x20 cm (8x8 inches). In my opinion, that looks more interesting than plain large-format or dull, common tiles.
