Chipboard outside Shower Cubicle

[Dundee_Stokie]

Hello guys, please could someone advise on the following scenario.
I seem to have had a constant drip from the shower (bottom of door), onto the floor just outside the shower door frame. This looks like it's been either creeping through a wee gap or the sealing rubber hasn't been up to the job. Either way its creating a bit of a mushy PB floorboard......once I peeled back the lino, then this was a surprise!

The problem is, the board is joined in the middle of the shower tray (if you are looking from underneath)....Do I need to cut this away and replace?

Thanks
P

the door frame and maybe the door glass is leaking due to poor installation.


first thing would be to remove the door and its frame, and then clean up all mould and old silicone.

the chipboard under the shower tray will be in the same, or worse, condition as the chipboard in the pics.
is the white sploge on the right paint or what?
the c/board can be cut tight to the tray with a multi-tool or a reciprocating saw.
it might be that all the c/board in the pics needs replacing including into the carpeted area.
but only you on site can make that call ie how soggy or damaged is the c/board?
the skirtings need to come off and be examined for rot.
likewise, the mouldings on the door lining look iffy?

Thanks for taking time to reply. Yes that's an old paint splurge.
If I cut the board tight to the tray, how does a new piece get installed? Just butt joint up against the remains and then screwed down on the joist further out? the damage is up to the carpeted area and that will also need to go, its one piece that will need replacing, its just how it gets re-joined as its continuous under the tray.

if the tray is trapped by the wall panels then it looks like the tray would have to stay in place.
having cut the c/board tight to the tray and removed it - you will then be able to see the joist arrangements.
if necessary, you can install noggins to give a backing along the cut edge.
replacemant c/board can be in two or more pieces - but all edges must be landed on joists or noggins.

is there an access trap in the ceiling below the shower tray?

Shower is en-suite on the ground floor, so no underneath access, there's a trap door just outside and when you lift up and stick your head down to see underneath - you can see a bit of mould/damage stretching further on (pretty much 1/3rd of the way into the tray).
