Not the solar shower, for the exact reason you mentioned. Solar showers are a lot like solar panels for recharging devices - they work but take too long to be practical for bike touring.
I have used the linked Ortlieb water bag for showering, perhaps 30 times. I mix 50/50 hot/cold water, heated from pot/stove. The 4L bag is just a little too small for a decent shower, really need ~6L but Otlieb only makes them in 4 and then 10L, and I didn't want to pay for or carry the 10L bag. I got 4L bag on sale from Wiggle UK for ~$15 shipped to USA The Ortlieb bags are lighter than MSR, and cheaper, but not as durable. Mine actually weighed 87g with the shower nozzle added, which is super light for any 4l water carrier.
