Finishing a shower off, nervous about existing work

[Tynan]

Hello all, I'm trying to finish various uncomplete jobs around the house after a builder walked away, his work was generally sound i think but towards the end he started hurrying stuff and cutting corners

At this momemt I'm tryng to complete a downstairs shower room. The shower body is in place and I've plumbed water into it and am ready to tile the back wall and tile it, at this point after some googling as to what to watch out for I have some doubts.

the left wall is tiled straight on to plaster, it's the party wall so maybe skimmed onto that? I can certainly see plaster under the tiles.

The right wall seems to be tiled straight onto some sort of ply, it's quite a mid brown and smooth so I'm hoping marine ply but no real idea, that's a stud wall built to form the shower room

The back wall ... there's 2x3 framework and four panels of ply that have a hole cut for the shower body, there's a recess of about a foot behind this and then a brick wall with the 'under the stairs' behind it, the supply comes from there and then through the wall.

I suspect the ply here is bog standard ply from the feel of it, there's also some voids in the central layer between the segments of that layer

I'm a humble DIYer and not that handy,I was happy plumbing and tiling this in, I'm now worried about a few things before I proceed ...

A. Is the tiling onto plaster on the brick wall going to be ok as regards waterproof and tiles staying up

B. Is the tiling on the ply wall going to be ok regard water and tiles

C. What to do with the back wall, is treating it with something and making sure it's well secured going to be good enough?

D. And finally, the metal shower frame for the door appears to be screwed directly to the tiles, it doesn;t look to be waterproof in any way to even an optimist, should it not have some sort of seal?

I've taken a heavy breather video that tries to show the ply wall, the edge of two sheets of the back wall ply, the plaster on the party plastered wall and finally the metal door frame screwed to the tiles

Is it sensible to carry on and finish the job as it stands or does it need all taking down and starting again, I've seen the tanking installation vids and they look very sensible.

The shower space is ground floor if that matters

many thanks, I really wanted to get this done this week but I don't want to be doing it again in the forseeable future

hi Tynan

do you have any photographs you could upload to this thread so our members can get a view of what you're looking at? This way, they'll be able to offer more specific guidance.

also, do you have an idea of what tiles you want to fix?

 

[Tynan]

Hi

I was hoping the vid would do that? Can you see it?

Two walls are already tiled, they're 'Barbetti Gres Porcellato - Full Body Stoneware' measuring 12"x21"

Here's some photos


The shower frame screwed to the tiles, metal frame stright to tile as far as i can see


View of the ply used for the back wall, showing a void? means it's not Marine ply?


The ply? behind the tiling on the stud wall, where it meets the back wall


The edge of the lower two pieces of ply on the back wall


The plaster behind the tiles on the party brick wall

if you can see plaster under the tiles , you mean between the joints , then he as dot and dabbed them , and imo that is no good

just noticed video link

large format tiles , i should start again , sorry

I struggle to see vids when I'm at work, as I don't have a vid player on my pc.

looks like bog standard ply to me, but does anybody else have any views to help Tynan with his project?

also, have you any idea of what adhesive your builder used to fix the tiles that are up already?

 

[Tynan]

I can see what I assume is behind the two walls of tiles up, in the gap between the tiles and and the back wall, ie the space for the back wall's ply and the back wall's tile, it's what I've tried to show in the pictures

I did have some professionals out a year ago who certainly mentioned that they'd have used cement board and mounted the door frame differently, although they also said the job so far was ok and they had no problem finishing it, but perhaps they're were happy just to finish off rather than tell me about problems

I have no idea what he used, sorry, he worked while we were both out out work, I trusted him to get on with (yes I know)

I now recall, in the bulider's defence that it's a tight fit for the tray, it's an exact fit between the party and stud walls, there wasn't much to spare between the width of the shower tray and the corridor outside

but that said, I presume the cement board or whatever isn't go take much space up and if necessary could slightly ovelap over the tray?

shower screen needs sealing on the outside only all the way round dont seal the inside aswater may get trapped

thank-you

the wife has given the ok to rip it all down and start from scratch with cement board and tanking if there's doubt about the way it's been dome until now

but the time and cost is a bloody pain, remebering how to plumb and tile is enough ag for me, she reminded me about next door's tales of wofe about having their new shower tiled three times before it was right and stopped leaking
