This may be helpful in multiple ways because I currently use a bidet attachment and my concern was how I could continue using it given that tankless toilets look incompatible with mounting the attachment. I already knew about toilets that have integrated bidets, but wrote them off because I feared they would not be appealing to future buyers (I am located in the US). However, if a bidet attachment was never going to work on a tankless toilet, then I would be getting an integrated bidet because I can't go without a bidet.
