I've got the design all but finalized and a list of most parts/dimensions. Now I just have to find someplace in Albuquerque to have the plywood wood cut. I'll assemble, but I don't have a table saw and don't want to make a mess or take the time to do it with a jog saw. I think I can cut the trim/moldings myself.
The shower configuration won't change much from how I've been using it, but I want to get some better way of hanging the shower curtains, those look a little cobbled together as they are. I'm about 5' 11 and showering is fine, but even in the middle there's not a lot of headroom for washing your hair, I need to bend the knees a bit when lathering the top of the head.
Eventually, I might want to put in fiberglass/plastic floor between the seats and a real drain in the floor, but you'd be surprised how well the plastic tub works, a bit of a pain to empty it into the sink, but only take a minute. A bit harder if I take a real long one and fill it up more.
But I don't think I can match the finished professional look of your fiberglass handiwork, inspiring. At some point I'll have to try to make something out of fiberglass.
