When deciding between the old rubber membrane system and the newer Schluter Kerdi drain system for a bathroom shower floor, it's important to consider the advantages and disadvantages of each. Here's a breakdown of both methods:
Old Rubber Membrane System
Pros:
- Familiarity and Preference: Many plumbers are familiar with this system and prefer it due to their experience and comfort with the installation process.
- Cost: Initially, this might be less expensive than the Schluter system.
Cons:
- Water Accumulation: One significant issue with the rubber membrane system is that water can accumulate and stay within the rubber layer because the drain is set slightly higher. This can lead to inefficiencies in drainage.
- Potential for Damage: Over time, moisture can seep through the grout and remain trapped in the rubber membrane, potentially causing mold growth and structural damage to the floor.
Schluter Kerdi Drain System
Pros:
- Efficient Water Management:This system includes a specific sloping and integration with the Kerdi membrane that directs any water that gets below the tiles efficiently towards the drain, reducing the risk of water damage.
- Durability and Safety: The design minimizes the potential for moisture retention, thereby reducing the risk of mold and structural damage.
- Modern Method: Schluter systems are modern and might offer more updated features compared to the traditional rubber membrane.
Cons:
- Cost:The Schluter system is slightly more expensive, though this cost can be justified by its benefits.
- New Technology:Some plumbers might be less familiar with this system, which could lead to hesitation in its use or potential issues in installation if not done correctly.
