    When putting in a new bathroom suite - i.e, shower. bath etc.

    Which is the best sealent in the market to put around shower tray and bath ledge, Sink to make it as much water tight as possible.

    Better off going with silicone or like seal trims?

    Thanks

    Spend a couple of extra quid on the silicone you choose and go for Dow Corning 785, nice and smooth to use and the pros recommend this all the time

    Dow Corning 785+ Bacteria Resistant Sanitary Silicone White 310ml

    Of course, its not just a case of buying the best sealant, which is what you have asked
    Its equally important how the bath and shower tray is fitted, how the tiles are fixed, wall preparation, how you apply the silicone and other issues as well
    Each of the above stages need to be correct so as to work together and provide a watertight system

    Is this a total rip out and fit ?

    Will you be tiling the walls around the bath and shower or just simply replacing the bathroom suite

    Have a search through the site as quite a lot of info on this subject

    Main points I would say are;
    • Use good quality, powdered tile adhesive and grout, not ready mixed with an "own brand" on it. If you use a tub adhesive go for something like BALGreenstar
    • Are any walls around bath or shower built with plaster board - either stud wall or dot/dab onto brick ?
            If yes then is recommended to rip out PB and replace with cement / tile backer board

    • Fit bath and shower tray first then tile down to bath / shower tray. As your putting bath and shower tray into position, pump plenty of silicone into gap between bath/tray and wall, push into position and remove excess
    • Once fixed in position, no movement of bath or shower tray
    • Dont grout gap between bath / tray and 1st tile but fill with a bead of silicone, level with tile face and allow to cure
    • After tiling is completed and grouted, then silicone all edges, make sure tiles are super clean before you start this with no grout/adhesive residue or dust
    Probably more details as well but anyway, this is all being done by your bathroom fitter yes ??

    I woud go for a seal strip fitted behind the tiles prior to tiling.
    After having many problems with silicon seals spliting this is now my recomendation.
    Even if the bath is ill fitted you should get away without any leaks with a plastic seal strip in place.
    This is the only thing that I look for - some baths have a raised edge on them so if you have one of these you need a profiled strip wereas if the bath as a flat edge go for a flat strip.
    Tappy,

  14. Well excuse me, I couldn't disagree more. Those sealing strips are very eightees, they look naff and they discolour with age. As long as you follow the siliconing suggstions above and you make sure you leave at least 3mm between the tiles and the bath or shower tray for a good bead of silicon you won't have any probs. |Also when the silicon gets black stains on it, which it will, you can cut it out and replace it.

    Ten years ago I would have agreed with you "NoOhmy".

    However, I have recently been to far too many leaks through ceilings due to the sealant coming away from the bath edge that I now always use the strip method when fitting baths.
    These modern strips won't discolour, make a very tidy job,need no maintenance and  will last as long as the bath does.

    Tappy,

    i always put clear silicon around the edge of the bath before it is tiled, then sealant after the tiling has been conpleted.with some baths you should fix a batten along the wall to support the edge of the bath.
     
  18. Don't do it 007. Your licence to kill will become a licence to leak. They are minging 'orrible things. Due respect to Crowsfoot, he has his way and I have mine, but by sealing the bath/shower to the wall and then the bath/tray to the tiles I have never had a problem (tempting fate and all that).

    Any builders merchant or DIY outlet should be able to set you up doubleoy.
    The one in the picture is a B&Q budget product and tops for baths with a flat edge.
    Whilst Wickes budget trim has a profiled edge more suitable for baths with a raised edge.
    Try the tile shops they are generally pretty good in their trim selection.


    P.S. I've just this week put right a leaky mastic job by chopping off the first row of tiles and fitting a trim behind before re-tiling.

    Tappy,

    The real problem is pretty near all baths and shower trays are plastic and no matter how well fitted you will get some movement and eventually this breaks the seal. Whether a sealing strip perhaps over sealed with some silicone will work better than just silicone who knows. The quality of the sealant will play a part but no matter how good the seal will eventually go
