Dear Customer,

Thank you for contacting us. These shower panel units are ideal for singular usage and would perform at its best when only one is using the water lines. If you want to install two, you may need to customize your water pipes (install water diverter/splitter) and possibly increase the water pressure in your lines.

I hope this helps. If you have any further concerns, please feel free to contact us. Our business hours are M - F, 9AM to 5PM PST. If your message is left after business hours, we will respond to you on the next business day. Thank you for your patience.

Kind regards,

Customer Support

The description says that there are three massaging jets. They aren't actually jets, but they do produce a mist., more like a steam generator. If I were counting on jets down the colum, I'd be disappointed. They aren't adjustable, to increase the stream strength....I don't think, or at least I haven't figured that out yet. :) I do love these and have gotten so many compliments.
