Some advises regarding wood cage with inside UTH

you can go much thinner than that. I use shower liner from home depot, it is thinner, cheaper and easier to work with. Or just buy a PVC enclosure and put whatever you like on the outside to pretty it up, basically make a cabinet around it. that is certainly the easiest and maybe even the cheapest way to go. I've converted 40 gallon breeders and 20 longs to enclosures, with quite a bit of work, mainly because I wanted them designed a very specific way that I could not find already available and because I already had a bunch of tanks laying around. making your own enclosures is involved if done right, mainly because of the needed fabrication to make them water tight and relatively vapor tight.
