Best Toilets for Small Bathrooms
Updated February 25, 2026
A standard elongated toilet extends 28-30 inches from the wall. In a small bathroom where every inch matters, that is too much. Round bowls save 2-3 inches. One-piece designs eliminate the gap between tank and bowl, making the unit look smaller and easier to clean. Wall-hung toilets free up the entire floor underneath. This guide covers which compact designs actually work and which ones sacrifice too much flush power for the space savings.

What to Know
Round Bowl Toilets (25-27 Inches From Wall)
The simplest way to save space. A round bowl is 2-3 inches shorter front-to-back than elongated. You keep the same tank, same flush system, same rough-in. The only trade-off is comfort -- round bowls are tighter for adults. For a powder room or half bath that guests use briefly, round is fine. For a primary bathroom you use daily, the comfort difference is noticeable. Best picks: TOTO Drake round (800+ MaP score at 1.28 GPF), Kohler Wellworth round ($150-$200), American Standard Cadet round ($130-$180).
One-Piece Compact Toilets
One-piece toilets have the tank and bowl fused into a single unit. They are not actually smaller in footprint than a two-piece, but the seamless profile looks sleeker and takes up less visual space. Easier to clean (no gap between tank and bowl where grime collects). Heavier -- 80-100 pounds vs 50-70 for two-piece. Best compact one-piece: TOTO Ultramax II ($350-$450, elongated but compact 28.4-inch depth), Kohler Santa Rosa ($280-$350), American Standard Boulevard ($300-$400). All are WaterSense certified at 1.28 GPF.
Wall-Hung Toilets (Maximum Space Savings)
Wall-hung toilets mount to the wall with no base touching the floor. The tank is concealed inside the wall in a steel carrier frame. The bowl projects only 21-22 inches from the wall -- 6-8 inches less than a standard floor-mount. You gain visible floor space, easier mopping, and a modern look. The downsides: expensive ($300-$600 for the bowl plus $300-$500 for the in-wall carrier), requires wall modification for the carrier, and future repairs mean opening the wall. Best for new construction or major renovations where the wall is already open.
Compact Elongated (The Compromise)
Some manufacturers make compact elongated bowls that fit a round-bowl footprint (25-27 inches) but have an elongated shape for comfort. You get the sitting room of an elongated in the space of a round. TOTO Aquia IV ($350-$450) and Kohler Veil ($400-$500) both offer compact elongated options. These are the best choice if you want comfort in a tight space and do not want to go wall-hung.
Buying Tips
- Measure your available space before shopping: from the finished wall to the nearest obstruction in front of the toilet. If you have less than 28 inches, round or compact elongated is the move.
- Check the rough-in. Small bathrooms in older homes often have 10-inch rough-ins instead of the standard 12. This limits your options further -- verify before buying.
- One-piece toilets are harder to maneuver through tight doorways. Measure your bathroom door width. A 24-inch door may require removing the door to get a one-piece toilet in.
- Wall-hung toilets let you set the bowl height anywhere from 15 to 19 inches. In a small bathroom used by both adults and children, you can set it at a compromise height.
Common Mistakes
- Buying a standard elongated toilet for a bathroom with only 26 inches of clearance in front. The bowl hits the vanity or blocks the door.
- Choosing a wall-hung toilet without budgeting for the in-wall carrier frame ($300-$500) and the wall modification work.
- Picking a compact toilet based on size alone without checking the MaP flush score. Some small toilets have weak flushes that require double-flushing.
- Forgetting that a round bowl needs a round seat -- elongated seats do not fit and overhang the front.
Bottom Line
For most small bathrooms, a round-bowl two-piece toilet is the simplest and cheapest solution. If you want elongated comfort in a compact size, a TOTO Aquia IV or Kohler Veil compact elongated is worth the premium. Wall-hung is the ultimate space saver but only makes sense during a renovation where the wall is already open.
