New Build - Damp/Leak (under shower) (Ed.)

Sorry double posting this as put in the wrong group initially so admins please feel free to shift where most appropriate.

Hi

We've been in a new build for 2 Years 3 months, within warranty time we've had them out for mould and condensation issues in the main bedroom, and damp patches in the ensuite multiple times in same area (just kept painting over and stain blocking)

Wednesday we noticed a watermark on living room ceiling (under wall side of shower upstairs)

Nothing massively obvious when looking under shower but could feel wetness, checked in cupboard that backs onto the shower, piece of the skirting was bulging a bit so took this off.. black mould on that, cut through plasterboard and it's very damp with lots of thick black/white mould and from we can see goes about 4 ft up the wall.


The housebuilder came out (as we. Said it must be connected to previous issue so under giver still) the handyman's checked it confirmed all connected and a crack was visible underneath the pan, must likely done on installation so we never would have known, everything will need replacing and redoing about a week's job he'll log with office.

An hour later office contact say the handyman says it's not related to the other issue phone the house insurance as they aren't touching it. Apparently we should've noticed a crack on the underside of the shower pan in our first 7 days of moving in.

I've attached some photos to show the state of it but was hoping someone could let me know if they seen this before and what the cause could be .... ( The highlight pink area is the damp on the shower door side that has been reported and painted over for months and keeps coming through, everything else shows the underside crack and the mould behind the shower wall)

The damp seems so high for a drip that's only apparently coming from the pan appreciate your thoughts

Shower walls built wrongly or with wrong materials I reckon

make me wonder if normal plasterboard was used behind tiles in shower


regarding the damp patch, if it was from the shower tray I would expect to see a larger patch in the lower corner, not a strip travelling up over a metre.


my opinion: remove Shower cubicle and tray and tiles / wall covering in shower and reinstate with proper damp proof materials ( I think skill builder has a video on this)


here is the video, it might give you an insight into the potential issues your shower has

Thanks builders are saying we're out of warranty but surely if it's like you say they have some ownership as initial build was wrong and issue has been ongoing since purchase not after warranty ended about 10 weeks ago

How is anyone supposed to 'notice' a crack on the underside of a shower pan?
Surely the fitters prioroty is to fit suitable materials to do the job properly.

Is that shower tray properly supported? The legs don't look right, kind of bulging between the supports
