I want to have a frameless bi-fold door for my shower. The only challenge for me is engineering a rail system at the top that will help support the end of the door furthest from the main hinge - C.R.Lawrence and U.S.Horizon (owned by CRL) don't have anything suitable, but I think I can make the rail from 1" square aluminum tube with a small wheeled carrier inside it that the door will hang from. The wall-to-glass hinges and the center glass-to-glass hinges are CRL's Hydroslide, so no problem there. If I can do this, the shower will look really good! My idea for this type of door is that when it opens after having a shower, all the drips remain inside the shower.
I'm using Delta Vero shower fixtures in stainless finish, with faux-stone tiles on the floor and sides, and the shower pan is custom-made stainless to eliminate any leaks. I even made the drain cover myself because I couldn't find anything ready-made that looked right! Everything is modern looking and very Euro-chic, just like how I want the entire inside of the bus to be. It's been a lot of work so far, but I hate cheap-looking plasticky showers like in most RVs, so for me it's worth it.
