Snake room design and build

[Skyrivers]

Thanks for the suggestions.

For back up heat I have a generator, plus the chimney is a dual flue with the other tap being set up on the other side of the wall for a wood stove.

I might rethink the flooring then.

If was me... would just paint and epoxy the floor. Easy to clean and if done correctly looks great. Throw some sand in the wet epoxy to give it more friction if you are worried about slipping. Would do same for the walls but would insulate them to help with temps.
