I'm an engineer and a DIY'er. I installed a GroheFlex rough-in valve in my bathroom remodel last week. It took me a better part of a day to frame / and stub out the valve. In addition, you want three body sprays, each with it's own volume control. All these valves have to have framing in the wall, and they all have to be plumbed together. Then he has to supply fittings / tubing, etc. He has to install the tub valve. The faucets aren't too much work.

How much work does he need to do for the drain lines?

If you think it's too high get another bid.

IMHO I don't understand why people want all these body spray showers. But that's just my personal thought.

you are right when you said "I don't understand why people want all these body spray showers". Now......I am,also, feeling the same way after looking at this estimate and will go something without body sprays.

So.....Geoffrey_B.......do you think it is reasonable? I have NO basis to judge hence I feel it is outrageous UNLESS you tell me otherwise.

Thanks for your reply.

I purchased Grohe: 35-026 GroheFlex rough in valve, 28-448 Shower Head, and a 19-849 Thermostatic valve with diviter. Plus the tub spout - and was somewhere around $1000 for a shower/tub setup.

I figure a licensed tradesman - will want atleast $60/hr - I'd say more like $75/hr - and I'd guess $125 for 'spot' work. The guy probably has 50% overhead for his truck / business insurance / health insurance / tools / overhead.

A bathroom is probably the most expensive room in the house. You want the valves installed correctly in the tile walls, level, to the proper depth, etc.

Have you seen his other work? Or spoken to previous clients? Is he going to do the work (I hope not sub it out, or give it to a 'helper').

I don't know how much material he is going to supply (fittings / PEX / copper / PVC) , etc

I think you would feel better in getting another estimate - but it may be apples to oranges - since you are changing the original design.

Not surprising. That's a lot of work.
