    Just found this sight, tons of great info. I am doing a bath remodel and was wondering if play sand is suitable for a mortar shower pan? I am doing a traditional (pre-slope, liner, top layer) pan. Thanks.... T

    'Sharp' sand is better, but play sand will work. Ratio of about 5:1 sand:portland cement for the deckmud.

    You might want to also check

    Personally, I'd rather have a shower made with a surface membrane, but a conventional shower as you describe is also reliable (and probably less expensive) than a surface membrane, but it does have advantages - basically, it dries out MUCH faster, which may be a factor when used multiple times a day, or in an area with high humidity levels. You might also want to check out and look at their Kerdi shower system. This is one of several competing systems, but is the 'original'.

    For the pre-slope anything will do just fine.

    Mapei makes a 4-1 ready mix. There is loads of mortar mix bags available as well.

    You should use a better quality product for the top layer.c Make sure it is no less than 1 1/4" but aim for about 2".

    Latecrete 3701 is a great quality mortar for the final top side layer.
