The best modern toilets for small bathrooms are compact models that save floor space without feeling cramped: round-front, compact elongated, wall-hung, and corner toilets. Many short-depth models measure about 23 to 25 inches from the wall to the front of the bowl, a few inches less than a standard elongated toilet.
This guide is for homeowners planning a small bathroom, powder room, or remodel. It explains the main types of space-saving toilets, compares nine popular models, and shows you how to measure so your new toilet fits.
Types of Space-Saving, Compact, and Corner Toilets
Round-front toilets have a shorter bowl than elongated toilets. A short-projection design can cut the distance from the wall to the bowl front by about 2 to 3 inches.
Compact elongated toilets pair an elongated seat with a shorter overall depth, so you get comfort without the full footprint.
Wall-hung toilets mount to the wall with the tank hidden inside it. They free up floor space, make cleaning under the bowl easy, add elegance, and make a small bathroom feel larger. They need an in-wall carrier and usually professional installation.
Corner toilets use a triangular tank that fits into a corner. They help in tight layouts and under staircases, and they preserve clearance between fixtures.
One-piece toilets with skirted trapways have smooth sides with no crevices, so they’re easier to clean in tight spaces.
Macerating (upflush) toilets grind and pump waste, so you can add a toilet where there’s no floor drain.
Tankless smart toilets use direct water pressure or a small pump to flush, so there’s no bulky tank behind the seat.

1. American Standard Cadet 3: Best Budget Compact Toilet
The Cadet 3 is a reliable, affordable pick for tight spaces. It comes in round-front and elongated versions, so you can choose the shorter round bowl when every inch counts. Most versions use 1.28 gallons per flush. The EverClean glaze helps resist the growth of bacteria, stains, and odors between cleanings.
2. TOTO Aquia IV with Washlet: Best Dual-Flush Toilet with Bidet
The Aquia IV is a two-piece dual-flush toilet that uses 1.28 gallons for solids and 0.9 gallons for liquids. Its slim tank sits close to the wall. The included Washlet electric bidet seat adds warm-water cleansing without a separate bidet, but it needs a nearby outlet. TOTO is known for its quality, so this is a long-lasting choice, and its smart toilet features also add convenience and can improve safety for some users in a small bathroom.
3. Kohler San Souci: Best Compact One-Piece Toilet
The San Souci is a one-piece toilet with a compact elongated bowl, so you get the comfort of an elongated seat in less space. Its comfort-height seat sits about 17 to 19 inches high, which makes sitting and standing easier for different users. The one-piece design has fewer seams to clean.
4. Kohler Veil Wall-Hung: Best Wall-Hung Toilet
The Veil wall-hung toilet hides the tank inside the wall, creating more floor space and allowing the room to feel more spacious. That makes cleaning easier and helps a small bathroom feel larger. Flushing is controlled by a dual-flush plate on the wall. Plan for an in-wall carrier and a professional installer, since the carrier and plumbing must be properly installed to ensure reliable performance. A wall hung model usually makes the most sense when the wall is already being opened during a renovation.
5. Duravit Darling New: Best European Design
Duravit’s Darling New range brings clean, minimalist European styling to small bathrooms. It’s offered in wall-mounted and floor-standing versions, so you can match it to your existing plumbing. Some European compact lines push space saving further—for example, Roca’s Ona range reduces toilet width by 200 mm. Its compact dimensions suit powder rooms, en-suite bathrooms, and other compact bathrooms where a modern look matters.
6. Swiss Madison St. Tropez: Best for Easy Cleaning
The St. Tropez is a one-piece elongated toilet with a skirted trapway. The smooth, enclosed sides cover the trapway, so there are fewer corners for dust and grime. It has a dual-flush mechanism and a soft-close seat, and its clean lines suit modern bathrooms.
7. Renovator’s Supply Small Corner Toilet: Best Corner Toilet
This corner toilet uses a triangular tank for better space efficiency, helping it fit where a standard model cannot as a practical design element in a tight layout while freeing up space around the sink and door. It’s a smart fix for a tight bathroom layout, such as a powder room under the stairs, and corner placement can complement nearby fixtures in a tight bathroom. Its round bowl also keeps the depth short, making this type an ideal choice when dealing with tight corners without compromising functionality.
8. Niagara Stealth: Best Water-Saving Toilet
The Stealth is an ultra-high-efficiency toilet that uses just 0.8 gallons per flush, about a third less than a standard 1.28-gallon high-efficiency model. Its vacuum-assist system creates strong siphon action to clear the bowl. It’s a good choice for homeowners who want the lowest water bills.
9. Saniflo SaniCompact: Best for Rooms Without a Drain
The SaniCompact is a self-contained toilet with a built-in macerator and pump. It sits on the finished floor and pumps waste through a small pipe, so you can add a toilet to a basement or small powder room without breaking up the floor. It needs an electrical outlet and a nearby water supply.
How to Choose Compact Toilets for Small Bathrooms
Measure the rough-in. The rough-in is the distance from the finished wall to the center of the floor drain. Most homes have a 12-inch rough-in, but older homes may have 10 or 14 inches. Buy a toilet that matches.
Check the clearances. Most US plumbing codes require at least 15 inches from the center of the toilet to a side wall or fixture. They also require at least 21 inches of clear space in front (24 inches under some codes), so you have enough space around the toilet for comfort, code compliance, and nearby fixtures.
Pick the bowl shape. Round-front bowls save a couple of inches of depth. Compact elongated bowls offer more comfort in nearly the same space, and choosing the right model means balancing measurements, comfort, and how it fits the overall layout when designing the bathroom rather than choosing the toilet in isolation.
Choose the height. Comfort-height toilets are about 17 to 19 inches high, which helps taller adults and people with limited mobility. Standard toilets are about 15 inches high.
Look at the flush. High-efficiency toilets use 1.28 gallons per flush or less, compared with 3.5 gallons or more for many older models. Dual-flush toilets typically use about 1.1 gallons for liquid waste and 1.6 gallons for solids. A well-designed siphon flush and a fully glazed trapway reduce the risk of clogs in narrower plumbing lines.
Think about cleaning. One-piece toilets and skirted trapways have fewer seams and crevices, which matters when there’s little room to reach around the toilet. Each element should also complement the room’s other fixtures while staying easy to clean.

Frequently Asked Questions
For most small bathrooms, the ideal choice depends on the bathroom layout as much as the bowl shape, though a round-front or compact elongated toilet usually works best. Many short-depth models measure about 23 to 25 inches from the wall to the front of the bowl, while standard elongated toilets often run 29 inches or more. Before you buy, measure your rough-in, the clear space in front of the toilet, and the distance to the nearest side wall, sink, or tub, since homeowners often need to find a model that will fit beside the sink or tub without crowding the room. Check the manufacturer’s spec sheet too, because dimensions vary a lot between models, even within the same brand.
Wall-hung toilets are often worth it if you’re already remodeling, especially when maximizing floor area is the priority. Because the tank is hidden inside the wall, they take up less depth and leave the floor open. That open floor area improves practicality in a small bathroom, while also making the space look and feel larger and making cleaning much easier. Whether it makes sense depends on your budget, wall access, and the overall renovation layout. You need an in-wall carrier, the wall usually has to be opened, and the job is best left to a professional plumber. If you’re not opening the wall, a compact one-piece toilet is the simpler choice.
Yes, as long as you choose the right features. Look for a comfort-height toilet, about 17 to 19 inches from the floor to the seat, which makes sitting down and standing up easier. ADA-compliant models meet this height range and work well with grab bars. A compact elongated bowl offers more room than a round bowl without taking up much extra space. Leave enough clear floor space in front of the toilet for a walker if needed, and consider a bidet seat for easier hygiene.
Most new toilets sold in the US use 1.6 gallons per flush or less, which is the federal maximum. High-efficiency toilets, including WaterSense-labeled models, use 1.28 gallons or less. Ultra-high-efficiency models like the Niagara Stealth use about 0.8 gallons. Dual-flush toilets let you choose a smaller flush for liquid waste. Look for the WaterSense label when you shop. If you’re replacing an older toilet that uses 3.5 gallons or more, switching to a high-efficiency model can save thousands of gallons of water a year.
