Cost to replace fiberglass tub/ replace with tub + tile?

[redredwine]

We're starting a guest bathroom remodel this week-yay! 
We were only going to do the floor/vanity/toilet/lights/paint, as the tub/shower insert combo is in decent shape. However; in thinking about it more, we're pretty certain we're just going to replace the tub with a better porcelain coated steel tub and tile the wall. 
so, from this type of tub:

 

To this type (and actually, this specific tile which we're using on the floor, too!) 




Our contractor will give us an updated quote when he's back from vacation on Friday, but so curious-if you did something like this, how much? We're not changing plumbing, etc. (obviously updating spout, etc.) We're in a MCOL area. 
The rest of our bathroom quote (including tile floor) is $1800 - (paying for vanity separately, they are installing). Hoping it's no more than $2k?

I'm guessing around $3000.
