    I'm planning on building a 3'x3'x4' and I've got a lot of questions. (I'm really sorry if these are obvious or stupid I have only have the slightest clue what to do). First question- is plywood acceptable? Second question- how thick should it be? I was thinking half an inch but that seems somewhat thick. Third question- how do you waterproof? I was thinking about just using a shower lining and covering the wood with it. Forth question- would glass doors or mesh doors be better? Thanks.

    Yes plywood is acceptable. For my enclosures I prefer 3/4 inch cabinet grade. Its a bit higher but it is already sanded and will save a lot of work, plus it looks good. I use several coats of polycrylic to water proof.
    And glass doors.

    Okay, thanks a lot. I'm planning to make a pond area in it, would the water proofing hold it okay or should I line it with something else..? Also, I was looking into boat wood. Wouldn't this be easier than plywood being as it doesn't have to be coated?

    I have not built any ponds in mine but if I were, I would use some sort of container. I am not familiar with "boat wood" but it would depend on exactly what it was sealed with. I do know that some people have built entire aquariums out of plywood and sealed it with marine epoxy but have no personal experience with this.

    I agree, 3/4" plywood is the way to go.
    I would cut out an area for a tub and have a support underneath.
    Epoxy would seal it sufficiently, however it doesn't smooth out all that well so doing a thorough cleaning would be difficult. With a tub or container you can remove for a good cleaning if need be.

    I've had good use with 3/4in marine plywood - expensive, but sealed polycrylic and topped with marine paint, it's never had any issues. - I've got a built-in pond in my enclosure. I added a 1" pvc drain pipe (with a valve obviously) for drainage. I carved out the wood and tapered it to help pull the water out. The only reason it get's a little less than fun to drain is because monitors like to make an absolute mess of their water... It may be over-engineered as far a enclosures go, but it's hard for me to constantly lift a tub of water out.

    I'll get some pictures later - I don't have anything in the enclosure now, so it's clean and freshly caulked (like enough to seal an elephant to a wall).
