When we bought our 2007 2350 new, Phoenix USA was installing those cheap white plastic faucets in the bathroom, shower, and outdoor shower. The kitchen faucet is better quality but is nothing fancy to the eye.
I have noticed, the past couple years, Phoenix has been installing better looking faucets of which I assume they are better quality.
I replaced our bath faucet with something nice for us seen below, but kept all other fixtures. Replacing the bath faucet is very easy, requiring no tools. Hand loosen, hand tighten. All fittings have wings for better gripping to hand tighten.
The drains are the lowest point in all our sinks and shower pan so they drain completelty, unless the RV is not level.
