  • Barrier-free shower system
    Patent number: 6178571
    Abstract: A barrier-free shower system having the combined configuration of a drain sump, drain and a continuously weighted shower curtain. A series of channels is formed into a threshold of a barrier free shower enclosure. The channels trap water within the shower enclosure and channel the water toward the drain sump. Water is directed to the channels from the base of the shower enclosure and from a shower curtain which hangs directly over the threshold. There is no lip or barrier in the base of the shower at the threshold to keep the curtain from billowing out as heat escapes the shower enclosure, so a continuous weight is provided near a lower edge of the curtain to keep it positioned over the channels in the threshold.
