Gear in the shower? I don't even wash my bike/boots near the house side of the driveway as the mud builds up in the drain in front of the garage door, use the street side. I've scrubbed the frame from my '03 in the shower just before powder coating, as it was winter time. Before I put a heater in the garage I have done clean work on the bike in the rec room with the pellet stove cranking. My wife is cool with that, as long as there is no gas smell.
Its easier and less mess washing a frame in the tub than my two pitbulls.
