VOF in Utarakhand is awesome you will not get to bath but if its ok with cold water then you can bath without soap at Hemkund sahaib, and hot water spring in Bathrinath.
for toilets better carry tissue paper as water is cold. u will get toilet and better home stays and hotels at gangariya, hot water will be available for 50 to 60 Rs. a bucket. dont expect hot water it will be warm water
I have been there in august and it was so chill that v dint took bath for 2-3 days. You can take along lots of tissue papers and wet wipes. :) rest there are also many small shops in govindghat and ghangharia .
