Cost for tile installation in a shower in Denver?

[Andrew George Dennis]

What do you guys think is a reasonable cost/sq ft for labor only to install new tile in a shower?  What if it includes replacing backer board as well?  The property is in Denver.  I’m talking quality work that will last.

On that note, does backer board always get replaced?

since I am a pro member now, can I ask for some recommendations for a good tile guy here?

Thanks !

Reasonable's got nothing to do with it. Market will be $6 - $20/sf. Depending... sole proprietor vs company with over head, legit contractor vs uninsured side jobber, type, size and quality of tile, shower walls and or floor, waterproofing, metal edging, niches, benches, shelfs, windows, deco bands, total square feet, backlog, substrate, relationship, layout. .. I'm sure I missed something... but that's why you get multiple bids AND why you need a detailed scope of work. 

You find a reasonable quality tile guy you let me know... ;)
