    Hi, my builder has offered to create a former from ply to get over some problems we might have with moulded former. This would go onto 6x2 joists. The kind of tiles I'm looking to use would be the patterned ones that are usually glazed ceramic. If everything is properly supported, would there be any problem with this?

    What issues do you have . Be far better to use a former.

    I can 100% guarantee that any former made by a builder using wood will fail.
    100%.
    I would bet everything I own on it.

    The tiles are completely irrelevant. If the shower former cannot be used without tiles, then it's not fit for use.

    Sorry to be brutal but it's the truth.

    Wet trays need to be made properly and even more importantly; installed properly.
    You need someone with a solid track record of installing wet trays to do this.
    Not a builder who is prepared to use ply.

    Well, if there was even the tiniest break in the waterproof tanking AT ALL you may find you'll be taking a shower and suddenly find yourself stood on your dining room table with your hands clutched around your most delicate of places.
    Using ply is a mistake.

    I am confident that I could make a former out of ply and that it would last, but that's with two considerations:
    1) I have years of experience installing and removing and rectifying wet rooms.
    2) The time and materials involved to create a successful former would cost far more than purchasing a wedi / schluter tray and adapting that, or the floor construction to overcome any problems.

    Apologies Paul for the brutal response.

    To answer the question a little more professionally:
    Yes, there are many MANY things that can go wrong with wood.
    First alarm bell is the very suggestion by a builder to make a former from wood.
    Now you possibly have an expert there, but the overwhelming chance is he is (with the best of intentions) going to cobble something together.
    Wood is never a good idea because it is not dimensionally stable, it expands and contracts with humidity, moisture and temperature.
    Even if it is waterproofed with a liquid or fabric membrane, it will ultimately fail in a short space of time - (disclaimer) unless this is done by an experienced expert who in 2017 should by now be using newer methods and materials.

    If you can explain the problems you foresee with a moulded former, perhaps I can be more helpful?!

    Maybe the 'builder' is a proper super duper tiler but is just reffered to as a builder.

    I once had a builder create a former out of concrete to a linear drain that was stuck up about 10mm. Needless to say, he was soon chopping it out

    Water and ply do not mix well together, keep them well away from each other!!!! Unless you like open plan living (between floors)

    Quite how this wall stayed upright is beyond me. It was 12mm ply that just turned to mush!!!

    The worst I've seen is tiles fixed straight to untreated MDF in a shower, the bottom row swelled up like that Hedgehog that they had to pop.

    I sorted one just before xmas, it was a raised up wet tray, a wooden frame with a piece of mdf on top and a drain grafted in the middle then mosaic. They only realised there was a problem when the shower door started catching the tiles as the mdf had swelled! To top it off the soil pipe was hanging off behind a stud wall and was leaking for 2 years, lovely

    In this day and age with the multitude of high quality materials on the market to make our jobs run so much sweeter and give clients installations longevity why do people still insist on cutting corners and using prehistoric methods which always FAIL EpIClY :fearscream::tearsofjoy: cue music Bob the builder!

    Probably John! Has done this before a couple of years ago and I made him chop it all out and put a former in so will probably end up the same way

    Thanks to everyone who replied. After much consideration I've decided to take no chances and go for a regular shower tray!
