New showers are definitely nice. I was in the H/K lounge on Nov 5 and was given an old shower. But when I was there last night (Nov 9), I got to use one of the new ones!

As rdude said, they're nicely furnished. Wooden benches instead of the "all-stone" look of the old showers. Nicely lit - not dark like the BOS AC showers. Shower head is nice and big - definitely an upgrade from the old drippy ones. The actual shower area has a glass door and 3 faux-stone walls - no more aquarium experiences like in the old all-glass showers.
