No pic, but if you're doing the blocking on the walls, then you should go ahead and put in the curb at this time. The curb will help keep the water from escaping the shower at the floor level. If you have the little blocked walls on either side, you could run the shower curtain rod from interior shower wall to interior shower wall (vs within the top of the doorway itself) and that should help with any splash around the sides of the curtain.

Hope this helps!

I never got my planned shower doors because I am so happy with the curtain! No glass to clean! I have a cloth shower liner, with a decorative cloth curtain that covers it. Single rod - I used to have double hooks, but after fighting with them, I just put in single rings and hung them both from the same rod. Maybe the two pieces of fabric keep them from blowing but I have no problem with it. I have hardwood floors in my bath, so am careful to not let the curtain fall outside the curb, but it's never been a problem. If I had kids using the shower, I probably wouldn't want to count on them keeping the curtain in place. Sorry no pics.

Olychick, thank you for finding those pictures. And, good to hear you don't experience the sticking problem of a billowing shower curtain. How tall is your front curb olychick? Also, I've never heard of a cloth curtain liner. How often do you wash it? (I'm only familiar with plastic-y liners with the cloth curtain on the outside as decoration.)

Our shower will be 3x5, and we do intend to put the lower threshold across the front (we can't do a no threshold shower because we can't sink the shower section... if anyone knows a different way to do it, I'd love to know, but at this time, we will have the curb).

We never installed shower doors. We just use a liner with a decorative curtain. We just toss them into the washing machine to keep them clean and replace the liner as needed. We use a curved shower rod which solves the billowing problem for us. We got ours at bed bath and beyond.

My curb is standard 3" 4"??? Not sure. The curtain liner is like some you see in hotels. I love it, think it is 100% polyester. I, too just throw it in the washer with bleach once in a while - it's taller than a tub size - available at BedBathBeyond. There are some online stores that sell taller and wider versions if you need them.

Thanks olychick!
