A nasty crack appearing in my shower pan :(

[MR. FUSION]

Nasty crack appearing in the shower? You sound like the wife when she sees me in the morning!

Has to redo the pic after removing some 'debris' :/

 

[Bonkers the Dog]

No debris in my crack, rubbed down vigorously after every outing with brush and Dettol, clean as a whistle, you could eat your dinner off it...

What you do in your own van is a matter for you

Is it possible for the OP to remove the drain outlet and check underneath what is supporting the shower tray. May need a flexi-scope or whatever they're called.

The odour trap may just be hanging in mid-air and need packing from the underside to relieve pressure on the tray. Key-hole surgery may be required

A plumbers 2 cent’s worth , The problem with all acrylic / plastic shower trays are they are Quite often formed around a square piece of wood , there needs to be space around the grating to be able to tighten up the grating nut , hence the week point , I have seen this many times in domestic houses

Thank you for that suggestion.

You need to try the tape, it's very good.

Nobody's saying that the shower trays should be bedded on three of sand and one of cement, but how hard is it to incorporate a decent sub base into the design ?

I have seen them resting on chipboard,,,bodgers,,BUSBY.

I wouldn't mess about with any do it repairs. Speedcoat and the guarantee that comes with it.

Looking at your photo, one wrong placed heal and it's going through. Get it done the sooner the better and some after photos would be nice please

Mr. Fusion you must definitely find out what's going on underneath the shower tray before you attempt long term repairs. If the structure below it is wood of some kind (very likely) then it's probably rotten and squashy. Fixing the tray and not the underlying support is asking for it to fail again in the future. If it is indeed wooden/mdf/ply then get some of this and apply liberally with a throwaway brush. I have used it very effectively to repair knackered window sills when the landlord "can't afford to fit a new window at the moment" you can drill some small holes from above and inject it using a syringe, available from craft sites on tinternet.

Speedboat did an excellent job on our shower tray when it had cracked

I can get to the exact area where the issue is and it's not wet at all, thankfully. I think it's down to two things, not using using the wooden shower plinth & putting to much pressure on the plug hole area (Mrs Fusion involved there!) The crack being further expanded by the fact (as correctly pointed out above) the waste pipe system into the tank is being held up by......the tray.... possibly... as the glue that is supposed to hold the waste pipe onto the base of the van may have failed. Further investigation required as I may have to solve this issue first!

Mending shower tray In my opinion doesn’t work, they eventually crack again, I went to the Hymer factory in Germany and purchased a new one and fitted it myself. I had ordered it on line and they had it wrapped and waiting for me. Fitting is not rocket science just time and patience required just like anything one does for the first time.

Hi Richard, How did you order the part online if you don't mind me asking? I have always had to go through a dealer?

 

[Thursdays Child]

Hi all, I have ignored this for to long, now this crack has deteriorated quickly. This is part of a huge plastic assembly in the shower unit which would be very difficult to get out. So any recommendations as to what I should try & to seal this up with? TIA

We successfully cured a crack in our plastic sink with Polystyrene Cement - the stuff used for making model aeroplanes.

 

[Chris CM]

You could always try truck bed liner, U-Pol do a range of colours, you could do several shower trays with one of their kits at a 1/3 of the cost of Speedcoat.

Yes thanks, have worked out what I need to do to get the whole unit out. Just a matter of getting hold of one. Will be a big job but most of it is simple screws & care. Note to self ( check tray will come out of bathroom door without removal) .

Have done a test with some - thanks for that.

With speedcoat you get a long guarantee that puts the cost up but gives you confidence in the product. I cant really see the negative vibes towards it. Im sure its a more cost effective way than changing the shower base for the same thing to maybe happen again as I previously said.

The poly cement has welded my test area very well!

If I do manage to get hold of a tray, I will be making sure it does not happen again. With extra support under the tray, if required & making sure the outlet pipe is solid & fixed.

In which case why not repair your existing tray and put in supports so it can't crack again and then get some anti-slip strips to put on the base to hide the crack and obviously make it safer in use (although I do like the look of your existing tape! ).

 

[Graham of Madrid]

If you remove the existing tray you've a great chance of a permanent repair solution that might be stronger than the original, strengthening the weak points for future proofing

We had several cracks around the shower trays in our Triango Tribute. Eventually the plug hole broke out of the tray. Our local Speedcoat specialist, repaired and supported the broken plug hole and covered the 2 trays and all around the toilet area. He took 2 days for the repair to harden and then spray the trays. Excellent workmanship, very satisfied. We sold the van 2 years later because the wife could not get comfortable in bed.

 

[MR. FUSION]

Thanks for all the input, Have done a temporary repair with polystyrene cement, which has very effectively welded the crack. I am also using the wooden tray (which probably should have been used in the first place ). So this will do until next year when I will organise a long term repair. I noticed have been putting the full weight of my heel on this point so it's probably why this has occured. I will also see if I can make up a bracket for the outlet pipe as it's only supported by the tank at present.
