Buying Guide: Wall Boards For Shower Installation
- Waterproofing method: Consider boards that integrate waterproof barriers or membranes (Kerdi-Board, GoBoard, or similar foam cores with fleece membranes) to minimize leaks behind tiles.
- Board thickness and substrate needs: Typical panels range from 1/2″ to 3/4″. Choose thickness based on wall framing, tile thickness, and desired rigidity; thicker boards reduce deflection but require more cutting and fitting.
- Tile bonding compatibility: Look for fleece-webbed or bonded surfaces designed to hold tile securely. Some products are specifically designed to bond tile without cementitious coatings.
- Pre-fabricated niches and shelves: If storage is a priority, select ready-to-tile niches or adjustable shelf solutions to reduce on-site carpentry and ensure consistent waterproofing around storage areas.
- Installation workflow: Some systems offer a streamlined workflow with integrated waterproofing and tile-ready surfaces, which can shorten timelines and reduce labor complexity.
- System compatibility: If you already use Schluter Kerdi systems, stick to Kerdi-Board products for optimal compatibility, seal integrity, and warranty considerations.
- Maintenance and future repairs: Choose panels with proven durability in wet areas and consider ease of replacement in case of damage or remodels.
