Complete bathroom projects are akin to remodeling a whole house in one room because they require all aspects of building. So when completing these projects, order is important. First you’ll want to make sure all mechanicals that need to be moved—are, and located in the correct place. This may require more demo to make the old pipes and wiring more accessible. Once you have all of the rough wiring and plumbing in place and HVAC installed, then you can move on to make sure all of the rough framing is done, insulate the walls, and cover with sheetrock or tile backer-depending on the application. Next tape, bed, texture, and paint the walls and ceiling. Once you’re finished with that, you can move onto the flooring, then cabinetry, and shower glass. Finally, you’ll finish the trims on the plumbing and light fixtures, and smile, because you’re done!
