Yes, DIYing bathroom refreshes like painting walls, replacing vanity hardware, and cleaning grout can save money and improve resale value. These cosmetic updates create a fresh look without requiring permits or licensed pros. However, if you uncover issues like hidden rot or faulty plumbing, hire licensed plumbers or carpenters to handle repairs promptly. Combining DIY finishes with professional fixes ensures your bathroom passes inspection and appeals to buyers while protecting your budget.
