I also see the T-bath as a fashion faux pas and don't think it will be changed during the first bathroom renovation, but I wouldn't build it anymore today - however: you can no longer rely on fashions nowadays. Twenty years ago, quite extreme high heels became fashionable - I used to know this as a reliable flash storm that disappeared again in the season after next, and today it is slowly fading away again. White cars were also reliably something that was once in fashion during my childhood and youth and three years later became hard to sell at used car dealers - again, currently this is different, white cars are a lasting trend. On the other hand: the carmine bay windows of the first series of [Anstattvillen] are already out of style, the smokey eyes are also declining (but significantly more slowly), the corner windows are a weaker but much longer-lasting trend. And I do not yet see the pizza-ordering TV studio kitchen even remotely on the retreat. I recently heard from [Moorhuhn] that it is preparing for a revival. In short (uhh, rather mediocre): fashions are no longer reliable today; if they are massive, then also short-lived, so you cannot rely on the T-bath, which in my opinion is superfluous, becoming a resale minus point in ten years (like the sanitary objects in moss green or Bahama beige back then). However, I still think: whoever has the courage today not to follow this fashion will not be penalized upon resale. Conclusion: if you personally really find it super cool, then yes, otherwise rather "classic" again.
