Can You Use Tile Backer Board Outside Corners in Showers?

Tile backer board, a crucial component of shower construction, provides a stable and waterproof substrate for tile installation. While its primary function is to ensure the longevity and integrity of the shower, questions arise regarding its use in exterior shower corners. This article will delve into the practicality and suitability of using tile backer board for outside corners in showers, exploring its benefits and potential drawbacks.

Benefits of Tile Backer Board in Outside Corners

Tile backer board offers several advantages when used in outside corners of showers, making it a popular choice among builders and remodelers:

Water Resistance: Tile backer board is designed to withstand moisture, preventing water penetration and potential damage to the underlying structure. This characteristic is particularly vital in shower environments where water exposure is frequent and constant.
Enhanced Durability: Compared to traditional drywall, tile backer board provides exceptional durability, making it more resistant to cracking, chipping, and flexing. This robust nature safeguards the shower from potential damage caused by impacts or movement.
Simplified Tile Installation: Tile backer board offers a smooth and flat surface, simplifying tile installation and ensuring a more professional finish. This eliminates the need for additional layers of construction materials and reduces the risk of uneven tile setting.
Reduced Risk of Mold and Mildew: The moisture-resistant properties of tile backer board mitigate the risk of mold and mildew growth within the shower enclosure. This contributes to a healthier and more hygienic shower environment.

Considerations for Using Tile Backer Board in Outside Corners

While tile backer board boasts various advantages, it is essential to acknowledge certain factors that might influence its suitability for outside shower corners:

Installation Complexity: Installing tile backer board in outside corners can be more complex than using it on flat surfaces. Achieving a smooth and consistent finish requires precision and meticulous work, especially when dealing with multiple layers of material.
Limited Flexibility: Tile backer board is known for its rigidity and limited flexibility. In situations where the shower wall experiences significant movement, the board might crack or break, potentially compromising the waterproof barrier.
Cost Considerations: Tile backer board is generally more expensive than traditional drywall, making it a slightly costlier option for shower construction. This factor should be considered when budgeting for the project.
Aesthetic Considerations: The appearance of tile backer board can be slightly different from traditional drywall, especially if the corners are not meticulously finished. This may influence the overall aesthetic of the shower enclosure.

Alternatives to Tile Backer Board in Outside Corners

While tile backer board is widely used in shower construction, alternative materials can be considered for outside corners, each offering unique advantages and drawbacks:

Waterproof Drywall: Waterproof drywall offers a more cost-effective solution compared to tile backer board, but its moisture resistance might not be as robust. However, it can be suitable for less demanding shower environments.
Cement Board: Cement board is another durable and waterproof option, offering similar properties to tile backer board. However, it can be heavier and more challenging to install.
Pre-Fabricated Shower Corners: Pre-fabricated shower corners are designed specifically for outside corners, offering a seamless and watertight solution. However, they might be more expensive and require specific installation techniques.

Ultimately, the decision to use tile backer board in outside corners of showers should be based on the specific requirements of the project, considering factors like budget, desired aesthetic, and the level of water exposure. Consulting with a qualified contractor or builder can provide valuable insights and recommendations tailored to the individual situation.
