I love ours. I found some cheap drainage tile on Amazon (called Gladiator tile. Searching drainage tile didn't bring it up) for the floor. It's much cheaper than Dri-tek tiles and softer on the feet.
We just put a bath mat outside the door and dry off and dress in front of the open door. We couldn't use it with the door shut - too closed in. But use a clear shower curtain it's fine. I use a heavy duty clear one so that I can give it a "push" and it will bulge out slightly giving more elbow room. Camping World sells a similar product that you can use as well... a glorified piece of tape and a string that you can use to pull the curtain outwards.
I don't get the argument about needing a place to get dressed. I'd always choose to get dressed in the TC area anyway and not in the bath - I'm not going to take my clothes into a bathroom when they are already packed 4 ft. away... our family never used the bathroom in our 26ft TT to dress in either.
It's just the 3 of us in the TC and after 20 years my DH has seen me in all conditions of dress vs. undress LOL. Since DS age 8 is with us I just hang up a curtain across the TC between the kitchen cabinets and the opposite upper cabinet to make a dressing room.
Try it on for size before you buy - sit on the toilet, bring in your shampoo/soap and see how you like it. Just leave your clothes on :) As a woman I LOVE having a place to sit down and shave my legs during the summer. And my toilet always looks sparkling clean. I am not germ freak that covers the toilet. It's plastic and made to get wet.
I did find that it got waaaay too steamy when we used it to hang up wet bathing suits and towels while we traveled. It was dripping wet. So I cut a piece of pool noodle and slip it over the edge of the door. DH put 2 small screws into the outside door frame and we use a small bungee cord to secure the door for travel. It gives it enough ventilation that everything dries out nicely now. I love that mod. Ours has a Fantastic fan in it and that thing draws so much air that anything we hang up will dry quickly from just the airflow while the fan is running. Another plus for us - swim suits and clothes can be hung inside and dried quickly. Sometimes there is no good place for an outside line in the sun. We tend to try for a shady site....
