Water-Efficient Toilets: Don't Flush Wasted Water - or Money - Down the Drain

OTTAWA, ONTARIO--(Marketwire - Oct. 5, 2011) - Whether you're buying a new home or just doing that bathroom renovation you've always dreamed of, choosing the right toilet can be one of the most important — and most often overlooked — decisions you'll have to make.

A high-efficiency toilet can help you save money, protect the environment and conserve water, all without sacrificing performance or peace of mind. With more than 1,000 different models to choose from, Canada Mortgage and Housing Corporation (CMHC) offers the following tips on how to find the right toilet for your family:

Water efficiency and performance:

  • To minimize your water use, consider buying a high-efficiency toilet. Newer toilets flush with 6 litres while high-efficiency toilets can provide adequate flushing performance with an average of no more than 4.8 litres of water per flush.
  • Decide what kind of toilet will best suit your budget and family. One-piece toilets, for example, are easier to clean, but they can also be more expensive and harder to install. Other options that don't generally impact performance include round versus oval or elongated bowls, single- or dual-flush models, and gravity or pressure-assisted toilets.
  • To ensure both water efficiency and high performance, look for a toilet with a WaterSense (WS) or Los Angeles Department of Water and Power Supplementary Purchase Specification (SPS) rating. These ratings ensure that the toilet meets a certain minimum standard of performance, quality, durability and efficiency while flushing with 4.8 litres of water or less.

Other considerations:

  • Measure the distance from the wall behind the toilet to the centre of the floor flange to make sure your new toilet will fit into your space before you buy it.
  • If you're tall, or have bad knees or a disability, you may want to buy a comfort-height bowl, which is slightly higher than a regular bowl.
  • Depending on your home and the climate in your area, you may also want to buy a toilet with a lined (insulated) tank, to help prevent condensation, or "sweating," during the summer. Ask your local toilet installer or retailer what's recommended for your area.
