Can a mini-widespread 3-hole sink faucet with 4-inch spread be replaced by centerset or widespread?
The problem with a traditional widespread faucet would normally be the sheer physical size. You will probably find that the girth of the spout where it meets the deck will interfere with the handle escutcheons/trim. However, if you find one that fits there should not be a problem.
Centerset lavs are typically fine to use where a mini-widespread was installed. In fact, the mini-widespreads are a (relatively) new type of product to give consumers a more decorative option for sinks originally designed for the formerly &quot;standard&quot; 4&quot; centerset lav.
