im not knockin these tiling course either but i served my time with pro tilers working in the commercial and domestic sector and i had so much to learn that i didnt even consider going on my own for years! during that time i made many contacts within the trade and now i get a constant stream of work from em !! the trick to making plenty money at this game tho apart form being good and reliable is to be reasonably fast! if you take too long to tile bathrooms no fitters will take u on and speed comes with years of experience!! so to answer the question my earnings are going up but to new tilers coming in i think some will struggle and probably give up!
