Use an invisible shower screen.

Pictures?

Move the shower curtain in a couple of inches. Yes photo's would help.

Thanks @GN I think we will go that route. And thanks to everyone else for your suggestions.

I suspect your contractor didnt do the proper 2" drop from entry to drain. You can measure it pretty easily. Did you get permits when you had the shower redone?

Or you could do as they do in Asian apartments, and not bother with a shower stall at all. (The entire bathroom is the shower. No kidding.)

Collapsible floor gasket. I saw these at a rehab place my dad was at.

Did you get the invisible shower screen? Do you like it? Does it work well?

What is an invisible shower screen? Looked it up and I just get versions of glass doors.

That was a joke ;-)

The only invisible shower screen is nothing at all (no door, no curtain) but usually it would have a larger shower area or the shower area would be designed in a way so the water will not splash or enter the main area.

Good. Thanks, I can be dense. Googling it I found a lot of glass and some items with the word magic in the name... Not a good sell for me.

We're redoing a tiny bathroom, 4x about 10 including the shower at one end. And it's a Jack and Jill and we actually need to keep both doors! 50's era with plenty of wear, so needs redoing. We hope to be able to grow old here, so redoing the shower w/o barrier. We'll use a shower curtain but concerned that even with the recommended 2" slope from floor to rain, water may get into the bathroom and out the door opening next to it that goes to the bedroom, where the flooring will not benefit from flooding.

A family member already has been diagnosed w a progressive disease so we are very aware of the need to prepare. No way to get ADA in an old house, but basically adaptive sure.

And it's a Jack and Jill and we actually need to keep both doors!

I have no clue what that means, but I'll refer you to what I said above a year and a half ago, ESPECIALLY with a tiny bathroom.

Not even joking. I've used showers in South Korean homes, and they worked just fine. I can't see a reason that anyone with a small bathroom needs a shower stall at all.

Since you're rehabbing the bath anyway, make the entire room waterproof. Install your drain in the middle of a tiled floor, put in a covered TP holder, set the towel racks well up on the wall, and get a sink faucet with a shower diverter (available at RV supply dealers). Spray away! It's fun. :)

The concern is the laminate flooring in the adjoining rooms. The doors are right by the shower. Is anything special to do at the doorway that would still keep the bathroom accessible for people using a walker?

The last thing I would want is a shower open to the entire bathroom. It is enough work to have to clean a shower after using, I sure do not want to clean my entire bathroom after a shower. I have seen this type of shower, but, if I looked at a house with one, it would be a walk away.

I actually saw something called "invisible shower screen" online, but it was a hard-to-understand site with a lot of mis-spellings. And it wasn't really that clear on what the product really was that they were trying to sell. It also looked like it would get all moldy and yucky. Here's what I saw:

A bathroom in which the shower is the entire bathroom must have a sloped floor to a floor drain. The floor must slope downward from the room door (or else you can do as we did in my room and ramp up a bit from the entry to a high point, then slope downward to the floor drain). I did a floor drain as a back-up to my curbless shower.

The drain is the square area in the tile about a foot and a half in front of the vanity leg.

If you have a small shower entry, not the 5 ft one we have here in the US for tub/shower combos, you can now get a shower screen that operates like a window shade. They are sold in the UK.
