At Hydrorelax, we're proud to share our expertise, helping clients make smart choices for their bathtub accessories.
Key Components of a Bathtub Audio-Visual System

1. Waterproof Bluetooth Speaker
Types:
Inwall (Hidden) VS. Wallmounted
Performance:
Waterproof Rating: The speaker should have at least an IPX6 rating to ensure it performs well in a humid environment without damage. (This ensures it works in bathroom moisture and water.)
Sound Quality: Clear high frequencies and balanced bass to deliver premium audio in a damp setting.

Materials: Corrosionresistant materials like ABS for longlasting durability.
Installation Recommendations:
Beside the Headrest: Closer to the head for an immersive sound experience.
Bathtub Edge: Ideal for wider sound coverage but may require more careful bathroom layout planning.
Water Resistance Rating for Bathtub Accessories
Rating | Meaning | Specific Protection Description |

Key Factors for Compatibility and Matching with Your Bathtub
Round Bathtub vs. Square Bathtub:
Different speaker layouts are required. For round bathtubs, speakers are best placed along the edges, while square bathtubs allow for a symmetrical arrangement.
TV Viewing Angle and Bathtub Curvature:
The curve of the bathtub affects the optimal TV viewing angle. Careful adjustment during installation is necessary to avoid screen reflections.
Dry-Wet Separation Design:
The control box should be installed in a dry area, away from water sources, to prevent moisture damage.
Pre-installed Wiring vs. Retrofitting:
For new bathrooms, pre-installed wiring is recommended. For retrofits, consider the available wiring space and the overall structure of the renovation.
Q&A - Frequently Asked Questions
Q: Can I add an audio-visual system to an existing bathtub?
A: Yes, retrofitting is possible, but it requires evaluating wiring space and installation options. For a seamless integration, we recommend considering a wall-mounted Bluetooth speaker.
Q: Will Bluetooth connection be affected by steam?
A: Using Bluetooth 5.0 or higher, along with anti-interference antennas, can effectively minimize the impact of steam on the signal.
