It is matter of comfort.
I own RV for over 30 years and for 20 had smaller units with small showers.
Than I bought conversion where shower was over 4ft by 4 ft corner bathtub and no curtain, but foldable door.
Combined with 100 gallons tanks that brought whole new dimension to boon-docking.
Than as I mention above, I am comfortable in Fleetwood TC shower, but not so in Lance shower, although to bare eye they look the same size.
I have never used wet TC bath, but from the looks, they will save 2-3" of floor space. Not worth it on 12' camper, although I guess that makes bigger difference on 8' camper.
