Hello and thanks for any feedback. I notice that most fixtures have 8" separation between hot and cold instead of the 10" I got, and escutcheon cover plates are too small for this as well, if I want to go with a single spout with hot/cold built in. Please see photos. I'd like to replace this with a new fixture. Can anyone suggest how to go about this? Any products I can purchase so when the plumber comes he have the right parts to do the job? Thanks again.
