If you’re dealing with a tiny bathroom, you need a toilet that fits — literally. In this 2025 guide, you’ll find the best space saving toilets designed for compact bathrooms, half-baths, and powder rooms. Whether you live in an apartment, tiny home, or just need more legroom, these picks keep things clean, stylish, and efficient.
Why You Need a Compact Toilet
Bathrooms in HDB flats, condos, and small apartments across Singapore and globally are shrinking. In fact, bathroom sizes have decreased by 15% since 2020 (Statista, 2024). A bulky toilet wastes precious space. A compact one helps you:
- Make room for storage or a sink
- Improve movement and comfort
- Boost resale value with smart upgrades

Key Features to Look For
Compact Depth (Less Than 28 Inches)
Stick to models under 28 inches in depth if you want real space savings.
Round Bowl vs Elongated
Round bowls save more space. Elongated bowls give better comfort. You need to weigh your priority.
Wall-Hung Options
They save the most floor space, but installation costs more. Good for long-term upgrades.
Flush Efficiency
Look for WaterSense or dual-flush models. These use 20–30% less water, cutting utility bills.
Expert Insight
“When working with small bathrooms, I always recommend wall-mounted or one-piece toilets. They open up the room and feel less bulky,” says Helen Tan, interior designer at SmallSpaceLiving.sg.
Installation and Fit Tips
- Measure your rough-in (usually 12″) before buying
- Check seat height if mobility is a concern
