Bathroom Tile Installation in Gilroy — FAQ

Why is bathroom tile more expensive than regular floor tile?+

Bathrooms require waterproof membrane installation, mold-resistant grout, more intricate cuts around fixtures, and careful slope work near drains — all adding labor time.

How long does bathroom tile last?+

Properly installed bathroom tile lasts 25–50 years. The grout and caulk will need maintenance every 5–10 years to prevent moisture intrusion.

Do I need to waterproof the entire bathroom?+

At minimum, the shower/tub surround and 3 inches above the tub must be waterproofed. Best practice is to waterproof the entire wet area including the floor.
