Converting an old water tank into a stunning outdoor bathroom is an innovative way to repurpose and upcycle unused materials. This creative build allows you to add a convenient washroom to your backyard or garden without undertaking a major construction project. An outdoor tank bathroom is also a unique way to provide rustic, industrial style to your outdoor living space.
Gather Supplies and Prepare the Tank
The first step is sourcing an empty plastic or metal water tank. A tank that is around 1000 liters or 250 gallons will provide ample space. You will also need plumbing supplies like pipes, a tap, shower head, and drainage. Don’t forget building materials to create the structure and roof. Safety gear like gloves and masks are essential too.
Thoroughly clean and disinfect the tank to remove any residue. Use a biodegradable cleaner and rinse well. Allow it to dry fully. Measure the tank dimensions and sketch plans for the structure. Consider how you will access the bathroom and any natural light and ventilation requirements. Remove any protruding pipes or obstacles from the tank.
Build the Support Structure
The tank will need a sturdy frame built around it to support the weight once filled with water. Wood, metal poles, or concrete blocks can be used. Ensure the frame is level by checking with a spirit level tool. The frame should lift the tank off the ground slightly to allow plumbing and drainage underneath.
Enclose the frame to form walls for privacy. Corrugated iron, timber, concrete, or woven bamboo sheets all work well. Make one wall removable to allow access to the tank valve and plumbing. Build a roof over the top supported by the frame to protect users from the elements.
Install Plumbing
Professional help may be needed to install plumbing unless you have experience. Pipes will be required to connect to an existing water supply or alternative water source like rainwater tanks. The tap and shower head can be attached directly to the tank or plumbed into pipes accessed through the tank wall.
Waste drainage is essential. A connection to existing household drains is ideal. Alternatively, a soak-well can be dug underneath. The shower floor can slope gently down to a drain hole. Consider hot water options like solar heating for comfort. Insulate pipes to protect from weather.
Add Finishing Touches
Install safety essentials like lighting and grab rails for accessibility. A tank cut in half placed nearby can act as a handy bench. Add simple landscaping like gravel or pavers for flooring. Plants around the outside provide extra privacy.
Painting the interior white makes the small space seem brighter and more inviting. Affixing wooden slats across the ceiling creates an attractive facade. A coat of varnish on the exterior protects from the elements while showing off the tank’s original patina.
Enjoy Your Private Outdoor Oasis
Your repurposed tank is now a functional outdoor bathroom ready to wash away dirt after gardening or rinse off after swimming. Not only is this bathroom eco-friendly and economical, it also adds vintage industrial charm to the backyard. With a little imagination, a humble water tank can be given an exciting new lease on life.
Frequently Asked Questions About Outdoor Tank Bathrooms
What size water tank do I need?
- For a small half bathroom, a 1000 liter (250 gallon) tank should suffice. For a full bathroom with separate shower, 2000 liters (500 gallons) or above is better. The bigger the tank, the more functional space you’ll have.
How do I clean and waterproof the inside of the tank?
- Scrub with biodegradable cleaners, rinse thoroughly, and allow to dry fully. Waterproof sealant like epoxy resin or a plastic liner can protect metal tanks from rust. Plastic tanks may already have an interior coating.
What basic plumbing do I need?
- Essentials are pipes to water supply, tap and/or shower head, drainage for wastewater, and insulation around pipes. Consider ease of access for maintenance. Hire a professional plumber if DIY skills aren’t up to scratch.
How can I heat water or cope with small space?
- Solar heating panels are an eco-friendly option. Small tankless water heaters work well too. Maximize natural light inside. Vents prevent humidity and odors. Paint interior white to brighten. Install mirror for sense of space.
What are some quick upgrades I can do?
- Add landscaping, like gravel, tiles, or pavers for flooring. A bench from wood or a cut tank gives seating. Simple lighting around the frame or inside creates ambiance for nighttime use. Plants or bamboo fencing increase privacy and visual appeal.
Will building codes allow this in my backyard?
- Requirements differ based on where you live. Many codes for accessory buildings like sheds apply here too. Consider zoning laws, height restrictions, minimum setbacks from property lines and dwellings. Check with your local council.
Conclusion
Upcycling an old water tank into an outdoor bathroom is a creative, eco-friendly solution for adding a stylish washroom to your backyard. With some DIY skills and the right materials and plumbing, you can repurpose a tank into a lovely private oasis to wash up after gardening or relaxing outdoors. This innovative project gives new life to an unused tank that may otherwise go to waste. Just be sure to check local building codes for any restrictions first. But once your tank bathroom build is complete, it is sure to become a beloved backyard feature for years to come.
