waterBOB Bathtub Emergency Water Storage Bladder (100 Gal)
The waterBOB bladder transforms a standard bathtub into a 100-gallon emergency water storage system.

Buying Guide: Key Considerations For 100-Gallon Water Storage
What storage method best fits your space?
Choose between bladder-based systems (foldable bags) and rigid bladders that fit in pantries, basements, or garages. Bladders save space and are portable but require careful handling to avoid leaks. Rigid, tank-style options offer durable, long-term storage but take up more space.
What about long-term water safety?
Look for food-grade materials (HDPE or PVC-coated layers) and liners that resist heat and contamination. Sealing integrity and UV resistance help preserve water quality in extended storage scenarios.
Ease of filling and dispensing
Bladders with built-in siphon pumps or compatible outlet adapters simplify daily use. Consider your discharge needs: household drinking water, cooking, or irrigation, and ensure your system supports the appropriate flow rate.
Portability versus permanence
Bladders designed for folding and light weight are ideal for mobile or temporary setups, such as RVs or disaster shelters. Heavier, stackable tanks suit stationary locations like basements or garages with less frequent movement.
Maintenance and inspection
Regularly inspect seams, valves, and fittings for signs of wear. Clean and dry the interior after use to extend the lifespan. Consider a plan for rotating water, especially when storage is unused for extended periods.
How to select the best option at a glance
- If you want to maximize space in a small home, consider bathtub-based or foldable bladders.
- For mobility in RVs or off-grid setups, prefer light-weight, foldable or compact bladder systems like the MXQMKL or GHOSOONE.
- If you need visible water levels, LATHEVEE’s graduation marks provide quick monitoring.
