The Best Toilets for Small Bathrooms

What Are the Best Toilets for Small Spaces?

The best toilets for small bathrooms combine a compact footprint with functional comfort, efficient flushing, and seamless style. Whether you’re remodeling a powder room or outfitting a tight en suite in a Vancouver WA or Portland OR home, choosing a space saving toilet model that suits your room layout, plumbing configuration, and personal preferences can make the space work better without sacrificing quality or appearance.

Flush Performance and Water Efficiency

For homeowners focused on water conservation and consistent flushing power, choosing a toilet with a strong MaP rating is important. MaP, or Maximum Performance, measures how much solid waste a toilet can effectively remove in a single flush. Toilets rated at 1000 grams are considered top performers. Most toilets we recommend carry a MaP rating of 800 grams or higher, which meets and often exceeds residential expectations.

In addition, we advise selecting a model with the EPA WaterSense certification, which ensures the toilet uses no more than 1.28 gallons per flush (GPF). Many older homes in Portland and Vancouver still use outdated models with 3.5 GPF or more, wasting thousands of gallons of water every year. Upgrading to a WaterSense toilet reduces water bills and environmental impact without compromising performance.

ADA Compliance and Comfort Height Options

If you’re planning a long-term solution or accommodating users with mobility concerns, check for ADA compliant toilets. These toilets typically have a seat height between 17 to 19 inches from floor to top of seat, which is easier for most adults to sit down on and stand up from.

While not every small bathroom can accommodate ADA compliant models due to height and clearance limits, many compact toilets now come in comfort height versions that align with ADA standards. Additionally, if you need a side-mounted flush lever for better reach or ADA accessibility, there are several compliant models available from brands like American Standard and Kohler.

Flushing Technology You Can Count On

Toilets today go beyond the standard gravity flush. Many of the compact models we install now include rimless bowl designs, siphon jet flushing systems, and dual nozzles for better bowl cleanliness.

TOTO’s Tornado Flush system and Kohler’s Revolution 360 swirl flush are known for covering more of the bowl’s surface with each flush, cutting down on cleaning frequency. While dual flush toilets offer the option to use less water for liquid waste, they can sometimes confuse users. Many homeowners now prefer single flush systems with water saving performance built in.

Top Toilet Types for Compact Spaces

Wall Mounted Toilets

Wall mounted toilets attach directly to the wall, with a concealed tank. This saves floor space and gives the room a cleaner, more modern feel. Installation requires in-wall framing and is best during renovations.

Back to Wall Toilets

These are floor mounted but hide the tank inside a cabinet or wall. They give a streamlined appearance and are easier to install than fully wall mounted models.

Short Projection Toilets

These models have a reduced depth, usually less than 27 inches. They are great for small bathrooms that need to meet clearance codes.

Toilet and Sink Combo Units

Perfect for half baths or powder rooms. They combine a small basin on top of the cistern, reusing handwash water to refill the tank.

Corner Toilets

Designed to fit into unused corners, freeing up wall space. They work especially well in tight, irregularly shaped bathrooms.

Why Should You Hire a Licensed Plumber for a Small Bathroom Toilet Installation?

Working with a licensed plumber ensures that your toilet installation is done to code, with no guesswork about fit or drainage. A small mistake with a waste line or incorrect flange height can cause leaks, poor flush performance, or even damage to your subfloor.
