full glass enclosure

If the pressure on the body sprays is reduced, their purpose is defeated.

couldn't agree more --- so, extend the drain somehow? any links or suppliers you know of? change them out for a different purpose in the shower? punt and tile over them?

Sophie: Is that a reasonable expectation from me --- I worked hand and hand with them on the design. Granted, I was not the professional here, that said, should I be able to request they work to correct it?

Did you specify this design or was it designed for you? That matters.

A full glass enclosure or clear shower curtain liner might stop the spray problem but that would totally change the intended effect of "zero barrier".

If it falls to you to eat the cost of major changes and that is cost prohibitive, you might consider foregoing the body spray jets and replace them with a pair of hand held sprayers with wall holders near the outside of the shower enclosure that hold them at more of an angle so they spray more toward the back of the shower enclosure rather than straight across.

Could you please draw a circle around "these openings"? Where is the drain?

Joseph: in the top picture, at the bottom, you'll see the drain, then a gap where it should meet the wall. Also, should be a link to a video, it will show my foot blocking the water path created by the body jets ...

Suezbell: We worked in tandem. Conceptually this was our design, but we ran all functionality by the installers.

@Joseph Corlett: not OP but the drain is the long metal part on the floor stopping a bit short of the glass enclosure (and the wall opposite the shower fixtures). It is visible in the bottom portion of both photos within the shower enclosure.

Your design. As suspected. Your nickel. Your issue. They executed only. You were the GC who hired them as technicians.

This is why you hire a designer. And a GC.

Adding a sliding glass door between the drain and the existing glass and/or a ridge behind the drain is not a perfect solution but it would be worth discussing with your contractor.

Could your tiler take the drain out and move it toward the other end of the shower?

How was the floor sloped for the barrier free shower. It looks like the bathroom and shower are too small to allow for the proper installation of a barrier free shower setup. From the darker center tile in the pictures it looks like water might be puddling or standing in the center rather than rolling to the drain. Is the floor outside the shower properly water proofed? If not the jets are not your only issue.

Nothing in the shower can be modified without affecting the waterproofing. At least I hope waterproofing was actually specified. As in, was this designed and constructed as a wetroom? Which system was specified?

This is a complete do over.

Or you never use the body jets.

Or you hope that a complete glass enclosure contains the water. Doubtful on that front. Especially if this wasn’t built as a wetroom.

"Granted, I was not the professional here, that said, should I be able to request they work to correct it?"

This is exactly the reason my customers get what, where, when, and why and I always keep how and who. Nonnegotiable.

Had these dufusses adopted my policy, they would have said, "Sorry lady, that ain't gonna work, ain't gettin' my name on it, here's your deposit back, and good luck."

I am guessing the plumber is blameless. However, a professional and qualified tiler should know the math involved in providing a properly sloped barrier free bathroom or wet room.

Did he advise against this design? Has he ever constructed a barrier free shower? Do you have inprogress construction pics to prove he did subpar waterproofing? Did you use a GC? Do you have a contract specifying scope of work and proper barrier free shower installation? Did you go with a low ball quote to save money or was this contractor's work on par with average or higher than average other bids? Did your tiler have a current license and insurance?

having a GC who hired and managed your subs would help you fight this mistake. If you acted as both GC and designer your recourse with or without using a court will be more difficult. Without a contract you would have zero recourse. Good luck.

I would not survive in that shower. There is such minimal Shelving, do you only have one bar of soap and 1 shampoo bottle?

Also, How do you expect the shower to stay warm while you are in it if all the steam can escape?

Design is all wrong. With that shower size, the linear drain should be against same wall as shower head, and you should have no body jets. Looks like a do-over to me.
