Bathroom Remodeling: Do-It-Yourself, or Hire Pros? Bathroom Remodeling Do-It-Yourself, or Hire Pros | Page 9
Summary
Unless your bathroom is unusually large, you can DIY most of the
smaller tasks within this larger project. For core-level bath
remodels, many DIYers still hire out electricians and plumbers but
do the rest of the work themselves. For surface-level remodels
that require no major wiring and plumbing changes, the entire
project is within the realm of the DIYer.
Professional contractors may do the job better and faster than you
can, however. So you will need to weigh cost savings against these
advantages when making your decision.
