Buying Guide
What should I consider before buying a 1-1/2 inch flexible tub drain?
Key factors are space in the bathroom, tub type (freestanding vs. clawfoot), and existing piping. A low-profile design helps in tight installations. Flexible or expandable hoses improve alignment between tub outlet and drain, reducing leaks and misfits.
Material choice: PP vs. ABS
Polypropylene (PP) offers corrosion resistance and high-temperature tolerance, with long service life for most bathroom settings. ABS is strong and budget-friendly but may require attention to compatibility with metal components and adapters. Choose based on your tub material, climate, and local water chemistry.
Length, flexibility, and connection
Measure the distance from the tub drain outlet to the floor drain or outlet. Select a kit with an adjustable or expandable hose to fit irregular layouts. Ensure the nut size matches standard 1-1/2 inch threads to prevent leaks.
Installation considerations
Look for kits that include gaskets or seals to enhance leak protection. Verify that the kit can be used in RV installations if you intend to move the tub between spaces. Avoid overly rigid systems for freestanding tubs in tight spots.
Durability and maintenance
Choose products marketed as corrosion-resistant and heat-tolerant for longevity. Consider ease of replacement if leaks develop, and whether replacement parts are readily available from the same brand or distributor.
