These are adhesive PVC stickers shaped like dolphins, designed for smooth bathroom walls. They suit renters or those wanting quick, removable decor without drilling or painting. Ideal for adding playful accents to showers, sinks, or toilet areas where water resistance is required.
What to look for
Material Durability
Look for PVC or vinyl materials labeled waterproof to withstand steam and direct spray. Avoid paper-based options that will peel or warp in high-humidity shower zones.
Adhesive Quality
Check for strong adhesive backing that resists lifting at the edges. Poor adhesives fail quickly in wet environments, leaving residue or falling off after a few showers.
Surface Compatibility
Ensure the decal is rated for smooth, non-porous surfaces like glazed tile or glass. It will not stick properly to rough concrete, painted drywall, or textured wallpaper.
How to use it
Shower Accent
Place a single large decal on the back wall of a walk-in shower at eye level. This creates a focal point that survives daily steam exposure without peeling.
Sink Area Decor
Apply a cluster of smaller decals above a vanity mirror to add personality. This area sees less direct water spray, allowing for more intricate designs or multiple pieces.
Toilet Partition
Use decals on the wall opposite the toilet to break up monotony. This spot is often overlooked but benefits from a playful touch that is easy to swap out later.

Frequently asked questions
Do dolphin wall decals leave residue when removed?
Quality vinyl decals usually peel off cleanly, but low-grade adhesives may leave a sticky film. Always test a small corner first and ensure the wall is completely dry before applying to maximize clean removal success.
Can you use these decals in a steam shower?
Yes, if the material is specifically marked as waterproof PVC. Standard vinyl may degrade under constant high heat and humidity. For steam showers, ensure the product description explicitly mentions heat resistance and long-term waterproofing.
How long do waterproof bathroom decals last?
With proper application on a clean, dry surface, they typically last one to three years. Lifespan depends on frequency of cleaning and abrasive sponges. Gentle wiping with a damp cloth extends their life significantly.
Verdict
Buy these if you want easy, removable decor for smooth walls. Avoid them if you have textured surfaces or need industrial-grade durability, where painted murals or tiles are better long-term investments.
