A solar shower bag provides a hot shower if there's any sunshine. An option is to get a Campmore Shower Pump for about $20 and use a 5 gallon bucket for the water. Fill the bucket with whatever temp water you prefer. The shower pump is battery operated and drops into the bucket. The shower head can be attached to whatever is convenient. There's a convenient, remote, on off switch so you can shut of the pump to save water and batteries when lathering up.
I used one of these when winter camping in my travel trailer. I had drains, but no water supply. I hauled water to camp and heated it on the stove for showering/washing.
Not being able to keep clean is NOT an excuse to avoid getting out! There's just too many options available!
