We have 2 bathrooms, both are small, but proportional to our 1972 house, and both had “issues”. Loose tiles in the tub and shower, floor tile/linoleum that was hard to clean and an overall dingy appearance.
For our master we opted to gut it and start fresh. Au revoir to the pink square tiles, too-short-for-Hubby shower head and linoleum square tiles on the floor
In the girls bathroom, we opted for re-glazing of the tub and tile rather than a gut. We replaced the floor tile, repainted and installed a new vanity, mirror and light fixture, matching the floor tile and lighting to our bathroom. From dingy to crisp and clean.
