The Essential Guide to Buying Bathtub Water Storage Solutions
When emergencies strike or you simply want peace of mind, storing clean water is crucial. Your bathtub might seem like an unusual spot, but with the right gear, it becomes a reliable temporary reservoir. This guide helps you choose the best bathtub water storage system for your home.
Key Features to Look For
A good bathtub water storage system needs a few key things to work well and keep your water safe.
Capacity and Size
- How Much Water? Most families aim for one gallon of water per person, per day. Look at the storage bags or liners that fit your needs.
- Fit Check: Measure your tub. Ensure the liner or container will fit comfortably without bulging too much against the sides.
Ease of Filling and Emptying
- Fill Port: Does it have a wide opening? A large opening makes filling from the faucet much faster.
- Drain Spout: Look for a sturdy spout or valve. You need to move that heavy water out easily when you are done.
Durability and Reliability
- Thickness: Thicker plastic or vinyl means fewer leaks. Check the material’s mil thickness if listed.
- Seams: Strong, well-sealed seams prevent catastrophic failure when the tub is full.
Important Materials Matter
The material your storage solution uses directly impacts how safe and long-lasting your stored water will be.
Food-Grade Plastics and Vinyl
Always choose materials specifically labeled as “Food-Grade.” This means the plastic will not leach harmful chemicals into your drinking water. Avoid reusing old, non-food-grade plastic containers.
Reinforced Liners
Many popular options use heavy-duty PVC or similar vinyl. These liners are often flexible, allowing them to conform to the tub shape. Ensure the material resists punctures; sharp edges on your tub can cause tears.
Factors That Improve or Reduce Quality
What makes one storage system better than another? It often comes down to protection and usability.
Improving Quality (Safety and Longevity)
- Opaque Material: Light causes algae growth. The best storage bags are dark or completely opaque to block sunlight.
- Airtight Seals: Good lids or tightly sealed tops keep dust and airborne contaminants out of the water.
Reducing Quality (Warning Signs)
- Thin Material: If the material feels flimsy, it will likely rip under the weight of the water.
- Poor Sealing: If the fill cap or drain valve leaks even when closed, the system is unreliable.
User Experience and Use Cases
How you plan to use the storage affects what you should buy.
Emergency Preparedness
If you are storing water for a long-term emergency kit, focus on durability and the ability to rotate the water every six months. You must treat the water (using purification tablets) before storing it long-term.
Short-Term Use (e.g., Camping or Short Outages)
For shorter needs, simpler, easy-to-clean liners work well. Look for systems that fold up small when empty so they do not take up much space in your closet.
Remember, using your bathtub for storage requires careful setup. Always place a towel or thin padding underneath the liner to protect it from rough tub surfaces.
Bathtub Water Storage FAQ
Q: What is the main purpose of bathtub water storage?
A: The main purpose is to store a large volume of clean water quickly when a natural disaster or utility failure stops your regular water supply.
Q: Do I need to clean the tub before using the storage liner?
A: Yes, always clean and disinfect the tub thoroughly before placing the liner inside. You want the storage environment to be as sanitary as possible.
Q: Can I use regular garbage bags to store water?
A: No. Regular garbage bags are not food-grade and can release dangerous chemicals into the water you might drink or use for hygiene.
Q: How long can I safely store treated water in these liners?
A: For best results, you should rotate or replace the stored water every six months, even if you treated it correctly.
Q: How much does a full bathtub of water weigh?
A: A standard bathtub holds around 40 to 80 gallons. Since water weighs about 8.3 pounds per gallon, a full tub is very heavy—often over 600 pounds!
Q: Are these storage systems reusable?
A: Most high-quality vinyl or PVC liners are designed to be cleaned, dried, and reused many times.
Q: What if my tub has a textured bottom?
A: Textured surfaces can be rough. You must place a blanket or thick cardboard under the liner to prevent the texture from puncturing the storage material.
Q: Do I need to add chlorine to the water before storing it?
A: Yes, if you plan to store it for more than a few days, you must add unscented household bleach specifically labeled as safe for water treatment.
Q: Are there options that don’t involve a liner?
A: Some people use large, collapsible, rigid water containers designed to fit inside the tub, but liners are the most common way to maximize the space.
Q: How do I get the water out when the power is off?
A: Use the built-in drain spout if available. If not, you will need a hand pump or a siphon hose to move the water to smaller containers.
