How to build a wood fired hot tub

Step 5Clad the cage

Apologies for the lack of pics for this step

Cut old corrugated roofing iron to length so that the corrugations run vertically. Cut enough to go around the tub.

Tip the whole thing on it's side to make it easier to work on.

Remove the plastic liner.

Start from the edge of one sheet and use a fat nail as a punch or drill to make 2 holes either side of the upper and lower horizontal bars of the cage. Bend the wire into a long U and poke the ends through the holes and twist together on the inside of the cage. Make sure you twist them so that they don't poke outwards into the interior space (where they'd snag on the plastic liner).

Continue around the tub adding more sheets as required.

At the top edge of the tub you'll need to tidy up the edges of the iron. With tin snips cut down the top of each ridge to a depth of about 2 - 3 inches. Make sure one side is just under the other and smack the ridge sharply with a hammer - this makes it form a nice bevelled edge with no sharp protrudy bits.
