Re: $42/sq.ft labor cost only for floor only tile install?
I'm with Houston on this one, without knowing more about the structure and the situation, there is no way anyone can definitively say anything about the price quote.
Pergo or not, that has to come out before starting, toilet too. Cabinet can stay or go depending on how it's installed, caulked, painted, etc.
The tile base has to be addressed. What is the subfloor and framing like? Is it sufficient to support the tile you want installed? Will it be over tile board or cement bed? Are these tiles 16" square, random sizes, ??? Is there any decorative trim being used within the floor pattern? Are you installing tile baseboard?
Then there are logistics such as where the bathroom is located in the house and how far away the installer has to set up his equipment and how much protective masking throughout the house he has to use. Regardless of him being 5 minutes away, he'll have at least one trip to the supply house for materials that will add at least one hour and vehicle costs to the job time.
His quote also likely includes incidentals that you haven't accounted for, such as the tile backer/base, grout, sealant, etc.
Lastly, as has been said, regardless of the job size and parameters, you should always solicit at least three bids, unless you already know and trust the contractor doing the work, even then the occasional additional bid will keep them honest.
Good luck with your project, let us know how it goes.
