Labor in a bath remodel is extensive.
Let's count the trade professionals needed in a bathroom project...
Designer, Tile Installer, Master Plumber, Electrician, Cabinet Installer,
Trim Carpenter, Shower Glass and Door Installer, Mirror Installer,
Sheetrock/Green Board Installer, Countertop Installer, and your Project Manager/Remodeler.
When a client asks me in surprise... My bath is going to cost me as much as my kitchen remodel cost?
I then communicate about how many trade professionals are involved and why.
Also, I give examples like these below.
When your new toilet does not work and starts to leak down into the first floor dining room ceiling...Do you want a legitimate licensed plumber who warranties his work or do you want a jack of all trades?
If your heated floor under your tiles stops working... your insured remodeler will come out to back the warranty of his work and materials.
Once you have a problem, one is comforted by the fact, that on their project, expert tradesman were used in their specific trades. They have guaranteed a warranty for their work and materials used.
In bathroom remodeling, the phrase " You pay for what you get" is very relevant here.
Plumbing is a science all of it's own.
Water has to come in and it has to drain out.
When bathroom fixtures are moved form original locations there is a lot of labor involved and a floor support structure to work around. Drains have to be placed in an exact locations for tub and shower for continuous draining of water.
If you would like to try to keep the labor cost lower, leave all positions of plumbing close to original if possible.
That may not be a solution for your remodel, then think practically with your remodeler where the water lines are and where they need to be. Does another bathroom back up to the bathroom being remodeled? Can water lines come a shorter distance from that location?
Another example of detail labor, body sprays in a shower do need additional plumbing work, there needs to be a continuous loop that connects the body sprays to each other.
A remodeled, updated, and working new bathroom is a joy to be in.
The path to there is easier with an experienced team of professionals.
