Shower tray, with lip

[faithhealer]

You know the type, 20mm up stance, sometimes two edges sometimes all the way round. I usually get the customer a 'plain' (no up stance) tray, recess into the wall, silicon, tile onto tray, silicon job done. This week repaired two showers with up stances, usual water damage. Tiles overlap into the tray but any water ingression cannot escape due to siliconed bottom edge' Hence water gathers behind the tile.
Take tanking membrane out of the equation for a minute, and tell me, are these (lipped) trays meant to be siliconed (look rubbish if they are not) A site manager has told one of my customers that they are not

one of these lipped trays caused my shower cubicle in my en-suite to fail within 6 years John. non-lipped ones are much better. talk the customers out of having a lipped one. show them my Before photos.

never do Liz, just curious to see if these trays cause more damage than they meant to prevent!

I have one to tile in a couple of weeks,again leak problem in a millionaire pad !!
The shop sold them a new lipped tray and said they'll have no more leaks,lol.
I told them to make sure the plumber sinks it into wall.
I had a argument with a plumber a few years ago about him not sinking them,him and the customer wanted me to tilt the bottom row of tiles ! so it was.... yuk.

A good argument for not sealing the tray to tile on these lipped trays, but it wouldn't look finished ??

I hate these trays. You turn up and they are not sunk into the wall, and maybe the corner isn't 100% square, so the upstand is 20mm away from the corner, and you are meant to slope the bottom row out over it. I think not

Have to say I put one in my own bathroom 10 years ago.
Did silicon the edges which I redo every 3 years or so.
Never had a problem. I think its all about how its bedded into the wall.

you should of just tilted the bottom row of tiles out like he asked you to and laughed at him when he tried to fix the shower surround.
