I admire you deciding to tile it, as that would be too big a headache for me! Presumably it will mean needing to cut the tiles to fit at the edges? Tiling it inside is certainly a solution though. It will make the base chewproof. If you're thinking of tiling the sides to make them wipe clean, then pet safe waterproofing paint would do the same thing. But tiling up to bedding height wouldn't stop a hole being chewed in the side above bedding height! If a hamster is going to chew through wood, they will find a chewing point, which could even be at the front round the front frame/struts. So I think the main thing is tile the base so the base and corners can't be chewed through. And be prepared to reinforce or protect other areas if the hamster does chew - which is an unknown factor at this stage.
I'd advise having the enclosure in a hamster-proof room (if that's not possible then maybe have a playpen around it), just in case the hamster does chew a hole overnight and escape. At least then you'll know where they are!
Do you know whether you're likely to get a Syrian or a dwarf hamster?
Which wood enclosure is it and what hamster do you have? Some will try and chew out of wood cages and some won't. It seems to be mainly Syrians that try and chew out (particularly female syrians). Some wood enclosures are made stronger than others as well. Is it a Pawhut you're looking at? For those, some people tile the base - apparently the wood at the base is quite thin. Corners are areas to watch as well. But I have seen instances of the hamster chewing through the wall (which is also quite thin).
