Hubby and I are new to bidets and I demanded one for our anniversary after lurking in this sub.
We are going basic to start with, no electric hookup. Elongated seat needed.
Costo has the Brondell CL150 and the Kohler Purewash M300 on sale. Opinions on both appreciated.
My biggest question is: we are both large people, are these seats sturdy? Nothing worse than shifting your tush and having the seat move with you.
