How do you stop water from running down bathroom walls?

- Install a shower curtain or shower door. This is the most effective way to prevent water from splashing onto the walls. Make sure the curtain or door is long enough to reach the floor and that it is made of a waterproof material.

- Apply a water-resistant sealant to the walls. This will help to repel water and prevent it from seeping into the walls. There are a variety of water-resistant sealants available, so be sure to choose one that is specifically designed for use in bathrooms.

- Install a ventilation fan in the bathroom. This will help to remove moisture from the air and prevent it from condensing on the walls. Make sure the fan is vented to the outside of the house and that it is turned on when you are using the shower or bath.

- Wipe down the walls after each use. This will help to remove any water that has splashed onto the walls. Use a soft cloth and a mild detergent.

- Re-grout the tiles. If the grout between your bathroom tiles is cracked or damaged, it can allow water to seep into the walls. Re-grouting the tiles will help to seal the joints and prevent water damage.
