Basalt Tongue & Groove Bath Panel

The Basalt panel offers an authentic stone-look finish with a subtle marbled effect that elevates bathroom aesthetics. It is designed for direct installation on a variety of surfaces and can be cut to fit. The tongue-and-groove system, combined with mouldings, creates a watertight seal when sealed with silicone. Best for buyers seeking a premium, stone-inspired appearance and reliable moisture resistance. Caution: verify surface compatibility and plan for silicone sealing during install.
Glacier Tongue & Groove Bath Panel

The Glacier panel uses a white marble effect to convey luxury while maintaining a practical waterproof design. It installs over existing surfaces and is easily adjusted for a precise fit. The two-step leakproof system with tongue-and-groove joints helps prevent moisture intrusion in humid spaces. Best for buyers who want a bright, timeless bath look and straightforward installation. Limitation: marble-pattern may show water spots over time without regular cleaning.
Champagne Tongue & Groove Bath Panel

The Champagne panel adds warmth with a glossy champagne finish and a seamless pattern. It installs easily over various surfaces and forms a watertight joint with silicone sealing. Best for buyers desiring a cozy, upscale spa-like feel in the bathroom. Caution: glossy surfaces may require more frequent cleaning to maintain shine and prevent streaks.
Mist Tongue & Groove Bath Panel

The Mist panel features a modern gloss finish with a soft, reflective appearance. It provides a seamless look and a reliable, leakproof seal using tongue-and-groove joints and mouldings. Best for buyers aiming for a contemporary, airy bath space. Limitation: lighter colors may show soap scum or mineral deposits more readily, so regular cleaning is advisable.
34″ W X 58″ H Single Fixed Bathtub Glass Panel

This fixed glass panel offers a frameless look with 1/4″ tempered glass for a modern shower enclosure. It pairs well with other wall panels for a mixed-material bath design. Best for buyers seeking a clean, minimalist shower screen that remains easy to clean. Caution: glass panels require careful installation with clamps and precise alignment to avoid leaks at joints.
Buying Guide
- Material and finish: Choose stone-look panels for a premium feel (basalt or glacier) or gloss finishes for a brighter, contemporary bathroom.
- Installation surface: Ensure the panel can be mounted over existing walls and that you have a straight, dry surface for best results.
- Leak prevention: Look for tongue-and-groove joints with mouldings and a silicone-sealed perimeter to minimize moisture intrusion.
- Maintenance: Lighter colors and high-gloss finishes may require more frequent cleaning to keep them looking new.
- Combination use: For a mixed-material style, consider pairing panels with a fixed glass bath panel for a balanced look.
