As the forum is forcing me to write another post, here's a picture of the water tank that now lives in the cellar (some making good to do around there as you can see, but the 'hole' it lives in is actually very neat). Can hold 300 litres at 70 degrees, so plenty to fill the bath with.
Do you ahve recent photos of your bath yet? Very curious how its turned out.
Ive got a mate thats just installed a japanese dunking bath or something. But its not being sunk into the ground so im curious how its going to look.
