So, is tiling super hard? Not something a noob can/ should do?
The main difference is you can tell the difference between a DIY and a decent tilers finish.
A good tiler knows how to set out a whole house, not just chuck a full tile in the first corner and hope for the best. Nothing worse than seeing a 40cm cut along the entranceway and small cuts in every room. Single room tiling (such as an ensuite floor) you might get away with this method, then, maybe not.
I set out the whole house before laying a single tile, by using 'bays' of 4 tiles (which I set out using the actual tiles). So the whole house is set out in a grid pattern of chalk lines. Takes about 2hrs to do first up, but saves a day per 100m2 of tiling. Entrances and hallways are made sure they have the best sized cuts, and small cuts are tucked away where no-one will generally look. These bays also 'take-up' and sizey tiles, so they arent as noticable than a tiler who uses a straight-edge. Good tilers know where to use closures as well, without impacting on look.
Bathrooms can be disasterous if you dont waterproof properly, or if you knick the waterproofing while tiling without care. Easily done, with massive consequenses.
Plenty of $h!thou$e tilers out there too Im afraid. Always find one that comes highly recommended - and not one from a retail tile shop!
