Sealing shower tray

[FreeD]

How would you go about sealing this shower tray?...its a Mira flight which has been fitted in the corner of the room onto floorboards by the plumber...there is a gap at the far end of shower tray which is approx 30mm away from wall. Also i've noticed movement in the tray when standing on it, i'd say it moves about 3mm.

I'm using 10mm thick ceramic tiles.







Thanks

that doesnt look like a 30mm gap in your picture, my advice is adjust the feet this will stop the movement in the tray, stick some slips of til e vertically where the gap between the wall and the tray is the thickness of the tile then skim from the edge of the tray using the tile slip as a ground and this will give you a flat surface to tile on , i would prime the walls first the use spf rapid the pull the wall out straight, if it is 30mm at its widest point ,you may have to step layers of backer board to get you to that thickness before you skim it out this would need to be screwed in to the wall .hope this helps

hi mate,personally i would be asking the customer to recall the plumber for 2 reasons

reason 1 being that there is movement in it which will be an unaceptable finish and you dont want any call backs from the job because of someone elses poor work

reason 2 being the 30mm void needs sorting....sometimes if the void is only 10mm i would use a rapid set with a floor trowel to fix the tiles with but i wouldnt be keen to do the job without that being sorted...

I didn't measure it thats just a guess..will check tmw...so Gary u are saying if less than 30mm say 20mm i should start from the tray and pack out the wall with adhesive until the tile sits on the tray? if more put backerboard on whole wall?

I feel like i should call the plumber back to sort the tray after all he put a massive whole in the freshly boarded and skimmed ceiling below...when i challenged him he claimed it wasn't him although he was the only person on site the day before...then i argued with him he admitted to it and said it was no big deal and that he could fix it in 5 mins

best thing to do is to take it out,but before you do mark on the wall where the tray sits,remove tray and chase the pipes back in to the wall a bit more if poss then chase the wall out so tray sits in wall so much then you wont have as much of a gap,then make up the rest (if any) with adhesive,but make sure you secure the tray properly via legs etc because any movement at all will crack the sealant later when the jobs done resulting in water getting through and damaging the substrate and in some cases going through ceilings.

The plumber that I work with would never put a shower tray directly onto floorboards he would always set it in on a miminum of 18mm ply.....get him back to do a proper job.

[kilty55]

are you being paid to install a shower tray and reset walls? i bet not ....id get monsiuer plumber back to sort his poor job 1st mate..if the hand was on the other foot would they accept shakey and squint tiles from you...i bet they wouldnt.

[garythetiler]

get the plumber to sort out the tray if you feel you are unable or unwilling to do it, however the wall preparation should be no problem for a tiler and over coming problems like this will certainly make you a better tradesman

As the yomper said they should never be put directly on floor boards to much movement i`ve never fitted trays with legs dont like them i like the acrylic capped stone ones then make my own plinth with strong timber frame and 18mm ply base and top, i make plinths cos not a big fan of putting trays directly on to floors traps/wastes should within reason have accessabilaty thats only my oppinion i`ve seen to many leeks in to ceilings cos of incorrect installasions of wastes and traps.

I've quoted to patch walls...i'm going to speak to plumber tmw...they are having a b&q tileloc floor put in don't know why this wasn't laid first then tray sat on top this would of at least made it more secure...don't think the customer is happy with the height of the tray anyway they were hoping for one floor level...thanks all for advice i'll lyk the outcome.

Hi freed firstly the tray needs to be secure this is the plumbers job.prime walls with tilers primer fill walls were needed?with maybe something like pci nanolight which has a high build, leave to dry and tank the walls with durabase wp or homelux waterproof matting.u need to use a powder adhesive for applying this and tiling.once youve done the matting u can tile straight away
when u do the matting overlap the tray by about 20mm then trim it once tiled and silicone
hope this helps

Ok spoke to plumber...tray is out...i'm going to level walls and strengthen floor (overboard) then plumber will refit tray chasing it into wall, i will then seal...bring tiles down on top and seal again...everybodies happy

Andy walls are concrete block + sand and cement so no need for tanking imo.

Is there a shower screed to go on top of the tray?

If so, whoever is fitting it should make sure that this will still fit on top once the tray's been chased into the wall.

Regardless of whether the tray is chased into the wall or not, you should still straighten the wall with spf.
