Will Empire Faucets RV Bathroom Faucet Cover Holes From Kohler 45100-4-2BZ-BA
Updated 08/28/2026 | Published 08/17/2026
Question:
Will this work to replace my kohler p/n 45100-4-2bz-ba in my 2018 airstream Tommy Bahama trailer. I want a single handle faucet to replace my double handle faucet without having to drill any new holes. Will the cover plate adequately cover the dual holes.? If so, do you also have the water line extension since this comes with such a short line for the cold water. Thank you

Hey Janeene! It looks like that Kohler uses 1-3/8" holes 4" apart, so 5-3/8" from outside edge to outside edge. I recommend verifying this to be sure. The Empire Faucets RV Bathroom Faucet # EM95PR base is 5-3/4" wide x 2-1/4" deep so assuming that is correct, it will be able to cover the existing holes from your Kohler.
We don't carry an extension for the included water lines, but the faucet uses standard 1/2" male pipe thread connections so you can pick up an extension from your local hardware or plumbing supply store.
Where are you headed next with the Airstream?

My Empire faucet base did cover the 4” on center holes. Should be fine replacing the Kohler. I really like the single control vs the old hot/cold!
