The one we got was really expensive, but it was the only brand available in Germany that actually has those things in the market for 10+ years (so it’s a well tested product). It’s one of the premium brands for bathroom “furniture” anyway, and the bidet ones are their top of the line bowls, so I guess in the end we’re not just paying premium for the bidet. Including installation and all the other parts, I think it was something like 3 or 3.5k EUR. I don’t really have any comparison (the cheaper brand would be around 1k less), but the thing is well thought through, has tons of options, easy to clean, easy maintenance, and has some really long warranty. I still feel I splurged on it, but in the grand scheme of things when remodeling a house (roughly 150k in total), I did not really register. Don’t know if that helps in any way…
