haven't had much time to work on it, and its sloow when i do with two little people helping.
but its nearly finished none the less.
inside of the back and two sides are filled in with 40mm poly, think there's enough left for under the tanks too.
Back and one side have seratone (plastic coated hardboard) for the outside cover
(taken off the bathroom when i decided to renovate it, must finish that...)
Cut the piece for the other side, but have to slide in the longest tank through the end before i screw it on. Top has seratone too.
Doors for the front are made, timber frames with seratone inside, then poly, then plywood outside, will open from the middle.
Still to make a little door for the bottom part, will open down to the floor, for storage space.
Tomorrow just have to slide the tank in, screw on the side, screw on the doors, make the bottom door, stick in the airlines and taps, line up the beam in the wall to bolt it to at the top, then it should be done and i can add the other tanks.
Can't wait
Think it will be insulated enough to just have heaters in the bottom tanks?
