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…
Remodeled the house including bathrooms, went for japanese style bidet (i.e. included in the toilet). Would not want to live without it.
water temperature, as well as pressure, is adjustable. I have on with different presets, so every family member gets to have their own favorite setting
not messy at all, has a very directed jet of water. Of course you can splash around sitting weirdly on the toilet, but that needs to be very deliberate. Mine has a function that when nobody sits on the toilet, the jet won’t start.
there’s options with blow dryers, but even if not, just one dab to dry off instead of wiping and wiping and wiping.
according to my plumber, it was one more water hose and an electric plug to connect. The device itself of course is much more expensive than a stander toilet. Just using TP now feels so terrible unhygienic. Imagine getting shit on your hand, and you have paper towels, or running water (and paper towels) to clean up. What would you choose? Maybe not really a “problem” solves, but a very, very nice luxury.
