Tips for Designing a More Sustainable Bathroom

For many homeowners, attempts at eco-friendly changes often start with the garden or maybe even the home’s power and heating systems. Sadly, the bathroom is often overlooked, even with its high water usage and energy demands. Given that most of us use it multiple times a day, it should be in your list of candidates when you’re reducing your environmental impact.

Fortunately, even if you have a very old bathroom, there’s usually no need to completely reinvent the wheel when it comes to making it more eco-friendly and practical to use. However, if you’re going for new builds or more complex renovations, make sure you get things done right by calling plumbers Dunedin property owners rely on.

With that said, below are some simple ways to make your bathroom more sustainable, with no compromises on comfort.

1. Look Into Water-Efficient Fixtures

While they might not seem all that different from those made 20 years ago, new toilets and taps consume far less water compared to older models. Switching to low-flow models or aerated taps can significantly reduce your consumption without sacrificing performance. Look for fixtures with a high WELS (Water Efficiency Labelling Scheme) rating to be sure you're making a smart choice.

2. Choose a Dual-Flush Toilet

One of the simplest upgrades with the biggest impact is replacing your old toilet with a dual-flush model. These toilets give you the option of a “half” or full flush, allowing you to allocate just the right amount of water for each use. Given that toilets get a serious amount of use, this is probably one of the most cost-effective and environmentally sustainable changes you can make.

3. Use Energy-Efficient Water Heating

Water heaters are a must-have for the Dunedin area, but they’re not necessarily on top of most property owners’ minds to upgrade. Whether your heater is a modern electric model, a heat pump system, or a gas unit installed by a licensed gas fitter, choosing one that’s right-sized for your property can significantly reduce energy use in your home. Consider adding insulation or models that have it built-in to reduce standby heat loss and keep your energy bills low.

4. Go for Recycled Tiles

If you’re doing a renovation, keeping your existing tiles is probably the most eco-friendly choice. But if you’re doing a new build, you can go for more interesting materials like recycled glass tiles as a way of keeping your carbon footprint low.

5. Pick Durable Cabinetry Materials

For countertops and cabinetry, reclaimed materials or those from easily replenished green sources like bamboo are probably your best bet. In any case, you want something durable and suited for moist environments. For example, while particleboard and medium-density fibreboard can be made sustainably, they’re liable to warp in a steaming bathroom, requiring replacement after just a couple of years. When in doubt, choose something you’re sure will last.

6. Improve Ventilation and Natural Lighting

Good ventilation is often overlooked in bathroom design, but it’s essential for an eco-friendly bathroom. First, it helps maintain indoor air quality, making your bathroom more habitable and less prone to mould. This reduces the need for harsh chemical cleaners, which can exact a toll on the environment. 

7. Opt for LED or Natural Lighting

If your bathroom is due for a full renovation, also consider adding a window or skylight to let in more natural light. The UV rays in sunlight can help further inhibit mould growth and keep surfaces disinfected, further reducing the need for harsh cleaning agents. As a major bonus, you can get away with keeping the lights off during the day, lowering your energy consumption.

If natural light is out of the question, good LED lighting is the next best thing. Compared to legacy fluorescent and incandescent technologies, LEDs are much more energy-efficient and long-lasting, making them the best pick for eco-friendly bathroom lighting. 

8. Seal Leaks and Drips Immediately

A single dripping tap can waste thousands of litres of water each year, not to mention the energy used to heat it. Every few months, look for hidden leaks under sinks, behind the toilet, and around fittings. If the problem is from anything more than just a worn washer, call a professional plumber immediately.

9. Install a Greywater Diversion System

If your plans are more ambitious, consider a greywater system to divert water from your bathroom sinks, showers, and baths for use in watering plants or cleaning the patio. This can be an extensive modification that requires proper design and council compliance, but it can be an especially powerful way to reduce your household water waste, especially if you have a garden.

10. Use Eco-Friendly Cleaning Products

If you’ve already gone through the trouble of setting up an eco-friendly bathroom, you’ll want to keep your commitment to the environment by choosing gentle, biodegradable cleaners. Even if you’re not planning to do your renovations soon, it helps to be mindful of what goes down the drain, especially if there is limited wastewater infrastructure where you live.

Greener Bathrooms Start with Thoughtful Choices

Designing a sustainable bathroom doesn’t require a massive budget or a complete overhaul. So long as you’re deliberate with your choices, even small upgrades can lead to big improvements for both your household and the environment.

If you're planning a renovation or need help assessing your current bathroom’s plumbing, be sure to talk to local professionals who understand Dunedin’s unique conditions. Whether you want to explore greener options or require emergency plumbing services, trusted expertise is never far away.
