As promised, here is my experience report. First, the hard facts:
Our gut feeling was confirmed in the showrooms. Like our house, we want the tiles to be clean and modern. My wife also wants the same tile to be laid in every tiled room, only possibly in different sizes. In terms of color, it should be a light, clear (so not with a brownish tint or too strong pattern) gray. I have photographed two favorites from the drawer. We also passed by a showroom bathroom with 30 x 60 cm wall tiles. I don't like that at all because there are so many grout lines. Next to it was a shower with 120 x 280 cm tiles. That was amazing. We also looked at different laying patterns. We have to stick with the cross pattern. :)
In summary, according to , our taste could be described as "Greek airport toilet but in light." ;)
What thoughts come to you professionals when you read my lines and look at the photos?
