I'm sorry, I don't have a solution for you, just replying so maybe someone else will see and have an idea. I think by shower screen you mean a glass panel that covers about half of the opening, like I've seen frequently in Europe, correct? (As an aside, I've never understood why they don't want glass to cover the entire gap, but I chalk it up to one of those quirky differences that we enjoy when we travel. :D )

I wonder if there'd be any way to put hinges on the wall that swing 180 degrees so you could then position the glass over the tub or open into the room.

Can you do fixed glass coming out from the window wall that meets fixed glass that is on the correct angle for the front of the tub, and have a shower door attached to the wet wall end that is correctly aligned at what would be a “door ajar” angle for any other shower? A stop to prevent it from coming into the tub with a magnet to catch a magnet on the door would hold it in place. I have no idea if there are glass door hinges that would do this, and it would mean no one could get into the tub by sitting and swinging their legs over, which is a significant drawback.
Alternately, you can have shower curtain brass rails made in any configuration. Check out curtain rods at any Victorian bath place, you may find what you need without getting custom. Try vintagetub.com

Thank you Nancy in Mich. You have some good ideas we can certainly nut out with the glazier. This gives me hope. The shower curtain and rail look beautiful but not practical for us except as a last resort. For some reason the first glazier considered and then abandoned the hinge idea. We'll revisit with the next glazier. It has also been suggested there may be an adaptable extrusion or chanel that could work. Here's hoping. Thank you and i'll be sure to post an update.

What is that hole to the left of the tub? It is the same height as the tub.

Can you put a glass panel between that "hole" and the tub, then put a folding shower screen on the front part of the tub. That way, most of the area should be covered. Some water may still leak or splash out. What is under the tile floor?

Some of the shower screens have one fixed panel with a brace and a swing out door. Some do not have the brace, and both pieces of glass fold in and out. I think these two are bifolds with no braces. With your tub, it would need a long, custom made brace if you had one fixed panel.

Do you have blocking in the framing to support a bifold door that folds into the tub or folds out?

Hi Peke. Thanks for the suggestions. Although waterproofed we will try and avoid escaping water as much as possible. That hole will be the laundry chute and the floor under the tile is both pine and hardwood floorboards. We do have the framework to support a brace, but not sold on the bifold door. Getting the right chanel and fixing it so close to the corner tiles is a concern. Even Check my diagram if it makes sense. It's looking more like a shower curtain with a fixed semi framed glass panel near the laundry chute may be the solution. Haven't given up though. Glazier coming next Tuesday.

Hi Designer Kitchen and Bath

It is a shower over bath. Came with the house. The rotten timber, frame around the bath and combination replaced., Yes, fully waterproofed. It is a highblocked house with another walk in shower downstairs.

"Although waterproofed we will try and avoid escaping water as much as possible."

With that setup a shower screen will not stop water from escaping, in fact a shower screen does not stop water from escaping all it does is limit it and keep in generalized to one area. The angle will not allow proper placement of anything as that is not designed to be a shower enclosure.

Josef, I see what you mean about that angle. Is there any way that angle could be changed? Remove the tile and cut the 90° angle off? Cheaper to do a shower curtain. Maybe you can find a curved rod.

Yes, the curved shower rod may be the best option.

I wonder if you can find an extra wide shower curtain though.

Oh. I hadn't thought of that.

Maybe a custom one? Plastic can't be sewn together as an inner liner, but they make inner liners that are not plastic. I don't know what they are made of, but two can be sewn together. Probably too wide then, but a seamstress can cut off each side so the center seam is centered in the tub.

Good idea. Thanks Peke. That's preferable to taking tiles off in order to fix the angle. Chalking it down to a learning experience.

Yeah! I have several of those experiences.

Do you have any "before" photos? Sometimes original solutions to odd installations turn out to be useful inspiration.

That's just great. It's a 1925 Queenslander with a lot of maintenance to be done. The tiler is a certified waterproofer so we expected it to be done correctly. The builder talked us through our options at length but didn't mention anything about the bath/shower or window other than suggest a new bath would give more space (it would't) or a new frame if keeping the tub. He did say the laundry chute is not to code but it will be when we are done. Beginning to understand why he ghosted us when we asked for a quote. We are inexperienced so pretty much stuck to what was there before, or so we thought. Just that angle got us in the end. The before photo shows the 3 panel sliding screen and how it butts up against the timber angled on that edge of the wall near the taps. I've learnt a lot. Think I'll cry now.

"I wonder if you can find an extra wide shower curtain though"

Use two shower curtains. But I cannot see anything really keeping the water inside this setup very well as this type tub is not designed to be a shower and then the entire wall deal...............

Think we will go for a fixed panel of glass near the laundry chute with brackets and connectors for a curved shower rod and shower curtain... or two.

We've had the house for 5 years and never had water escape from the previous fixed panel & 3 panel sliding screen. Guess time will tell if the curtain works.

Even though the tiler/waterproofer is licensed we've requested a statement of compliance. Seems all should be ok since we've recessed the bath, used fibre cement sheeting for walls and floor, waterproofing membrane then the tiles. Just the screen or curtain to come.

Although the bath does not meet current code because it has no lip, it is an existing bath that did meet code at some point, and is just a retile.

Our tiler has given us hope having seen the same angle successfully screened in other local bathrooms.

Waterproofing appears to be correct or at least we are covered if it's not.
