Rethinking the Tank: Tankless Toilets Save Water and Space, But Are They Right for Your Bathroom?

As the name implies, a tankless toilet does without the bulky reservoir to free up much-needed space in a small bathroom. But this modern commode delivers more than just looks -- it saves water as well as space.

Thanks, But No Tanks

Your basic john is a gravity-fed system relying on a tank above the bowl to deliver a rush of water to flush waste down the drain. The tankless version rejects this convention, directly connecting to the supply line instead.

Tankless toilets are common in commercial buildings where supply lines have enough force to effectively cleanse bowls after use. In homes, however, it’s a little trickier. Most residential supply lines do not deliver adequate pressure. To get around this, tankless toilets can be installed with a small pump as a flushing aid.

A More Efficient Flusher

Today’s plumbing efficiency standards demand that new toilets do not exceed 1.6 gallons of water per flush (gpf.) Your outdated throne uses about twice the amount per flush. Privies manufactured before the 1980s are even more wasteful, sending about 7 gallons of water to the sewer after every use.

Upgrading to a new toilet, even a conventional one, will save you a substantial amount of water, but some tankless models kick efficiency up a notch by allowing the user to customize their flushing preferences. A dual-flush feature gives you the option to throttle back flushing force to 0.8 gpf, conserving even more water.

Cool Stool

If your bathroom remodel is aiming for a modern, minimalist aesthetic, a tankless toilet certainly lends itself to a more contemporary atmosphere. It would also do well in a small water closet where floorspace is at a premium. Another benefit: They can be wall-mounted at any height for a more comfortable sitting experience.

Pricey Privy

A tankless toilet comes with a steeper price tag and it is definitely not a DIY project. It will require a professional installation. A retrofit of your plumbing may also be in order. Bottom line: Going tankless will cost more upfront, but you’ll benefit from the smaller water bills down the road. Plus, it’s just a more stylish latrine.
