Thread: the drain is higher than the shower

  1. #1

    Default the drain is higher than the shower

    Hoping to get a pre- and post hottub shower installed so as to minimize chemical use and cool off after a hot soak. In the basement where the tub is, the 4" drain pipe comes through the room from the upper floors and has a cleanout a few inches above the floor. it should be easy enough to put the shower on a pedestal and get a pump to take the water up a few inches to the drain.
    1- what brand or model of pump works best?
    2- whats the techniqud for using the existing drain? A cleanout cap with a flange on it? Is there a such thing?

    Any help would be greatly appreciated.....
    Thanks in advance,

    So, the pipe runs horizontally through the area you want? Or, does it go down into the slab with the cleanout a little above the floor?

    The shower would require both a p-trap and a vent. A typical 2" p-trap is probably about 5" deep plus the thickness of the shower floor (pan) and probably some other things requiring height. This could make the floor height a significant step and affect headroom as well.

    You could do a conventional shower, right on the floor, if you used a sewage pump. This would allow you to also put in a toilet, and a sink as well - maybe put in a bar for the guests with a small sink and a drain for the icemaker! Ceiling height can often be an issue in a basement, so putting things up on a pedestal is not often a great idea, and it always looks cludgy.
