Anyone know how the true measurements of the photo wet bath compare to the standard corner shower, as was in our ROO and lots of other trailers? Or even the "tub" that's been around forever? On the upside of the wet bath shown, I can see it being a huge help for those with needs for a shower bench....this would serve 2 purposes. Our DS#1 has to use a shower bench and in our ROO there was not room to put it, and I'd bought a smaller size to take along rather than his larger one. No go and he and DH had to use the shower house.
