If that is labor only, that seems high. I do many bath remodels similar to this but not having seen it I could only venture a guess at labor. For one guy it would take me about 2 1/2 weeks @ $40hr. that would be $4,000.
I have just sent out a proposal on a bath much more extensive than yours, relocating tub and toilet, moving vanity 6", new tub, tile tub and floor, vent, vanity strip light, pocket door and skim coat walls and ceiling. She will spend about $7,000 labor and material.

@Don, what area of the country are you? And what is your trade? (Are you considered a GC, or do bathroom remodels specifically/only?) Just curious.

It does seem high to me, but its someone i personally know so i need to figure out how to approach this.

Thanks for your feedback holly. I was told he was going to use hardiboard backing. Does that sound appropriate? He is license, bonded, and insured and I know him personally. I just wanted to make sure the quote is fair, because in general it seems like a lot for the work that will be done considering there's just 1 sink to add for plumbing.

Hollysprings, I am a Kitchen and bath remodeler,I have more work than I need, no advertising and do nothing but repeats and referrals. I don't know where you live nor do I care but If you have handimen screwing in light bulbs for $40 hr. then PT Barnum was right.
I do not work by the hr. but figure proposals at that plus 15%.
A modest bath remodel as I described, in the mts. of NC. will be under 10,000 labor and material. The job the poster is describing would be 2 1/2 weeks for me alone and if I charged $7800.00 for 2 1/2 weeks of labor only I couldn't sleep at night. By the way, that would be $78 hr.

I would also like to know what is meant to be used in bathrooms - I also thought Greenboard was the right product.

What should be used?

We paid $10,000 for a bathroom remodel a while back. I know it was high though.

I just did a bath remodel in Philly. I had estimates all over the map. Most were in the $32-42K range (but those subcontracted out a lot of the more specialized labor (i.e., tiling, electrical, plumbing) and charged what appeared to be a 25% mark up on all materials). I ended up going with a highly recommended contractor, but having to buy all of my own materials.

My bathroom is about 110 square feet and the total remodel cost was $10,750, and the finish materials were an extra $15K (contractor supplied the copper, pvc, shower liner, thin set and mortar, lumber, hardibacker included within his price). It took 18 work days. Having to buy all of the materials in a pain and took a lot of time; I guess that explains the reason for the mark up many charge.

For some reason, it's not letting me post the link to my post on my remodel. You can find it if you'd like to, or just use this:

This estimate seems like a bit higher considering you buy materials- and this is only labor. I believe you can get better estimates! Good luck!

The more relevant consideration may be the amount of work days the estimate is calling for. That's the only way to compare apples to apples (if that's even possible). My remodel was similar to yours in terms of the demo, etc. but I moved everything but the toilet around and added a separate tub and shower and replaced a window. Your labor doesn't sound that extensive and the bathroom is smaller (although that wouldn't make you labor half the cost).

I am getting a new revised bid sheet from him in the coming week. Will post then. He had his tile guy come by and they stated that the 6"x24" porcelain could have a problem with warpage and its a difficult install. I told them just do a 1/8" grout line and they should be fine. Thanks guys.
