How to Hide Cracks in a Shower Tub

Cover the crack with a bathmat. These mats are waterproof and are often used to prevent slipping in the shower. However, they are also effective for the purpose of covering minor cracks or the leftovers of repaired cracks. If the crack is a small or hairline crack, a bathmat can provide a temporary, cosmetic solution.

Repair the crack yourself. Wash the area with soap and water, allowing it to dry thoroughly before proceeding. Create a small hole on each side of the crack with a drill to prevent the crack from spreading, then sand the area around the crack. Fill the crack with waterproof grout, spreading it with your finger. Allow it to dry. Cover the repaired area with plastic sealer, spreading this with a putty knife. Once dried, the crack no longer leaks or spreads in the bathtub.

Install a bathtub liner over your existing tub. These liners cover the old, damaged bathtub with a fresh, undamaged piece of material preformed to the shape of your tub. Not only do they cover cracks and prevent them from creating more damage, these liners give your bathtub a brand new look to freshen up your bathroom. Each liner must be installed according to the directions in the packaging.

Hire a contractor to refinish the bathtub surface. This is the most costly option but is an effective way to repair any major or minor cracks in the tub, along with stains, discoloration and any other damage the tub has suffered over time. The contractor will wear away the topmost surface of the tub using abrasive products, fill in the cracks, then cover the bathtub surface with a fresh glaze to make the tub look new.
