shower over bath with no lip.... I have a bit of a situation to deal with. The owner builder has bought a tub for a shower over bath situation. The bath has no lip. I googled all morning on flange kits and stuff and apart from verbal instruction (without much detail), I couldn't find detailed instruction with diagrams. My head works best with pics and I often can't follow verbal instruction on things I've not encountered before without good pics.
I guess I'm asking, pretty please, can someone explain with diagrams how to make this bath/shower waterproof. I'll be standing the wall up in a couple of days and wonder if alcove or drop in is the way to go.
Also, one of the end walls will be a cavity slider and I'm assuming that can't be notched for alcove or take any plumbing. Is this correct? Never worked with cavity sliders before. Wondering how to get around that as the shower head would have to go against that wall. The bath has outlet in the middle, by the way.
Cheers for any advise, Su.
If I had to do this job I would install a pvc angle along the wall before the sheet goes on, or stick to the sheet and seal it to the bath when installing the sheet, leave just enough angle on the bath so it will be hidden under the wall tiles.
The sliding cavity wall will not take any plumbing, you will even have to cut the tips off some screws to avoid scrathing the sliding door.
The only way around this is a false wall for the plumbing and then a wall (or frame) for the slider.
Good luck.

Thanks Oldsaltoz.
So, I would set the bath edge into the studs then a PVC angle over the face of the studs and down onto the bath? What would you use to seal it?
The outer edge of the bath will sit on a frame so this would have to be sealed differently? How would you do this?
The false wall is going to be a bit of a tight squeeze. I don't have the figures in my head but I may only have about 50mm to play with. Hope it's more. Will find out today.
Just by the way, I am not doing the plumbing, sealing or tiling. I just want to know how best to get it right for the tradies without any major issues arising.
Cheers, Su.

Thanks Oldsaltoz.
The wall issue is sorted. Apparantly it's on the opposite wall that the plumbing is going (no cavity slider).
Its just the wrong bath for that situation, for it to meet the standard without it being installed as a drop in it will look like absolute cr*p for ever and a day.

Thanks Inter. Yeah, Wrong bath but trying to make it right, if possible. Owner had already bought it and has very tight budget so buying another bath would hurt her. As it is, she will likely be moving into an unfinished house if she can get away with it. So drop in would be best? Have I understood the PVC angle correctly (pic)? Anything you can add would be greatly appreciated.
Cheers, Su.

could you return it and swap it over? might cost a few dollars now but cheaper than new bathroom in 2yrs once this one rots out.
you could maybe sheet all the way to the floor on all sides of the bath except leave the angle coming out then membrane before bath goes in under and around bath.
rather than using angle "z" maybe a better profile from behind the villaboard then the tiles sit ontop of the section coming out then full sealant junction to tub.
Shauck, almost right, villaboard first under the angle, waterproofer to do this as they will give a warrantee. do bath as a drop in then cove tile around the wall over the top of the bath.

Thanks inter, gazza. Don't suppose a pic of either of your solutions is around anywhere?
Can't get my head around your drawing. Can you include the edge of the bath? It doesn't look right
I've coloured the bath red in new pic. I didn't include cement sheet under tile or bedding or waterproofing. It's not to scale either. I guess I just basically need to know that I construct something appropriate for the waterproofer/plumber/tiler to work from. If anyone can fix my pic to show how it all goes together, I'd be really thankful. I'm not good with verbal but i try. Pics are my saviour when I find it hard to understand. Also, just to be clearer, this pic is for a drop in bath. If I can make that work, I think Nik (owner) would prefer it.

I would fix the sheet to the wall so it was above the bath with a 3 to 5 mm gap between bottom of sheet and top of bath.
Then cut the angle to length and lay it on the edge of the bath with the upstand facing me, I would then apply sealant to the far face of the section now laying flat on the bath, and then apply sealant to the upstanding side of the angle on the bath side.
Then slide the angle under the sheet and stand it up.
The aealant on the section that was flat on the bath will now contact the back of the sheet, the bit that was standing will contact the bath.
You now have a seal on the bath and the wall sheet.
Good luck.

You could get stainless steel or alumnium profile Bent by roof flashing or metal work guy to be used to suit this job. All ideas are using a Silcone seal to Prevent water egress
I thought your drawing was of the wall side.
Is this what you mean?I would fix the sheet to the wall so it was above the bath with a 3 to 5 mm gap between bottom of sheet and top of bath.
Then cut the angle to length and lay it on the edge of the bath with the upstand facing me, I would then apply sealant to the far face of the section now laying flat on the bath, and then apply sealant to the upstanding side of the angle on the bath side.
Then slide the angle under the sheet and stand it up.
The aealant on the section that was flat on the bath will now contact the back of the sheet, the bit that was standing will contact the bath.
You now have a seal on the bath and the wall sheet.
Good luck.
Yes, that's the location for the angle.
Good luck,

it doesn't meet the standard though because the bath should have a lip.
regards inter
Thanks again guys for explanations and drawings. I've told Nik it's never going to meet the standard as it's the wrong bath for a shower. Wondering, if I do a drop in and before the frame is built, the walls and floor are waterproofed, build the frame, cover with cement sheet and waterproof, then put bath in, with PVC angle and sixaflex as per my last pic and waterproof. Can't imagine there's much more that can be done??
PS. Thanks for all you're patience.
Waterproofing a shower over bath:
Seal all penetrations first, taps and shower head supply and bath spout.
At the shower end waterproof the corner at least 1.4m up between bath and shower head.
Waterproof at least the lower 150 mm of the wall right around the bath.
Also seal over any securing screws or nails.
Good luck.

Thanks oldsaltoz. I think I've got it. Much appreciated for all your patience.
