Mr Whitaker had his second bath in two weeks on Saturday after technical adjustments were made to the donated bath which has been set up outside his snow cave.
"It was my first bath in a week.
We brought the bath in last Saturday [18] and set it up and tried it out so I had a quick wash but it wasn't working as well as we hoped, just getting the heat source right."
The Remarkables received 5cm of snow on Saturday night and his second bath proved quite relaxing.
"It was snowing last night when I was having a bath ... I sat down and had a beer in the bath while it was snowing."
Mr Whitaker has been living in a self-built and continually evolving snow cave near the Remarkables skifield's car park since August 11 to raise money for Aspiring Avalanche Dogs. To date $6000 has been raised as a result of his stay.
"People have been really generous when they come off the mountain. A couple of people put $50 notes in [to a collection container at the site]," he said, although people could also donate online.
Mr Whitaker proclaimed the cave felt like home after the two weeks and the frustrations of trying to keep himself and his equipment dry were now part of "normal routine".
"The only issue I have had is I burnt my gloves trying to dry them on the side of the fire bath."
When spoken to Sunday morning he said he would be spending the day frantically trying to add more snow pack to his quarters before any of it started disappearing.
He was due to host a guest on September 10, the winner of an online auction, which at present stands at $400.
While the winner's sleeping "shelf" was still a work in progress, Mr Whitaker said he had already nicknamed it the "West Wing".
He was living on packet meals which only needed hot water added. The winner would also be dining on such food, although Mr Whitaker has been "saving" a packet apple pie to share on the final night.
