I acted as general contractor and did all my own demo to remodel my 6x8 bathroom. I hired subs individually to do most of the work - an electrician, a plumber, a drywall guy and a tile guy. I painted the walls and the ceiling. I replaced everything except the cast iron tub. Materials and fixtures cost around $2000 and labor was about $3000. My subs had no problem with me supplying the materials, because I discussed their job scope in advance. This project took 6 months but I did have another full bath to use in the mean time.
20% labor price ---out of the question----I'm a Building Contractor, If you are totally remodeling a bathroom, where is the cost for demo of existing???? Demo can easily run an extra 10%- factors: 1) Age of existing---many factors here to adjust price, 2) Accessibility ---Getting materials out of and to the bathroom, and protecting present surroundings of owner. 3) Cost to dispose of debris 4) Where is the Contractor's O & P ???
It's totally legitimate for a professional to charge you for a design, at least in some situations. If the contractor has a book of ready-made designs and just pulled one out to show you, then you're right that s/he shouldn't charge you. But if someone does a design that conforms to your room's dimensions, with the features that you want, then that person has invested time in creating a work product. Some contractors and architects think that's just the cost of doing business, but many others consider that their time is worth something, and they charge for it. You just need to let contractors know that you're not looking for that kind of custom work, and not willing to pay for it.

The angles where any two planes meet in a wet area, such as the shower, tub, and countertop need to be filled with a flexible material to absorb movement and seal up this section to keep it watertight. This is usually done with some form of caulk 6, either latex or silicone. A tube of caulk 6 costs around $20 and this is usually installed with the tile, shower, or counter with the cost included in the tiling.

Be brutally honest about your DIY skill level. Assess which projects to do yourself and which are better left to the pros. You could save yourself a ton of money in the long run if you don’t have to call someone in to fix a project you’ve messed up. The best way to find a good contractor — seek referrals from friends, family, neighbors, co-workers and others who have had remodeling work done.

There are so many beautiful things to notice about this bathroom that it's hard to know where to start. The concrete sink? The wallpaper? The sconce lighting? The tarnished mirror on the door, reflected in the main mirror? The barely-there ultra-modern faucets? Whatever you notice first, though, you can't but admit that this space is a masterpiece.
