I’ve got a Duravit toilet here in the US, and I'm on the hunt for a compatible cold-water bidet seat under $300 on Amazon. I originally went for a Brondell, thinking it would match the shape and dimensions. But halfway through the install, I realized it wasn’t going to fit around the seat connectors. Duravit's own bidet seats are around $1,000-- I'm tempted, but they look like a lot of work to install. I’m starting to wonder if I should just upgrade the whole toilet to a model that comes with a bidet.
