When designing or renovating a small bathroom, every inch matters. One fixture that often gets overlooked—but can make a big difference—is the corner toilet. Whether you're remodeling a half bath, finishing a basement, or planning a tight layout, this compact solution might be exactly what you need.
In this article, we’ll explain what a corner toilet is, how it works, and when it makes sense to choose one.
What Is a Corner Toilet?
A corner toilet—also known as a triangle tank toilet—is a type of toilet specifically designed to fit into a 90-degree corner of a bathroom. Instead of the traditional rectangular tank, it features a triangular-shaped tank that allows it to nest neatly between two walls that meet at a right angle.
While the bowl usually resembles a standard toilet, the key difference lies in how the tank is angled to save space and optimize the room layout.
How Does a Corner Toilet Work?
Functionally, a corner toilet operates just like any other toilet. It connects to the same water supply and waste outlet and offers familiar flushing mechanisms—such as single flush or dual flush systems.
What sets it apart is the shape and placement of the tank. The tank is designed to sit snugly in the corner, which shifts the overall footprint of the toilet and frees up valuable wall space elsewhere in the bathroom.
Some models, like our 17 inch comfort-height corner toilet, also come with added features like water efficiency and ergonomic seating—so you don't have to compromise on comfort to gain space.
Why Do People Choose a Corner Toilet?
1. Maximizing Tight Layouts
A corner toilet is ideal for powder rooms, small apartments, RV bathrooms, or attic conversions—any space where a standard toilet simply won’t fit comfortably. By tucking the tank into the corner, the overall footprint of the toilet shrinks, allowing for easier movement and better use of the room.
2. Creating Flexible Design Options
By freeing up straight wall space, corner toilets give you more freedom to position other fixtures like sinks, vanities, or towel racks. This can be especially helpful in narrow or awkwardly shaped bathrooms where conventional fixture placement doesn’t work well.
3. Supporting Renovations in Older or Unusual Spaces
In basement remodels or old homes with non-traditional layouts, plumbing lines may not be ideally located for standard toilet placement. A corner toilet can provide a creative workaround without requiring major structural changes.
Things to Know Before Installing a Corner Toilet
Instead of listing pros and cons like a product review, let’s walk through a few key considerations to help you decide whether a corner toilet fits your needs.
✅ It Fits Where Others Don’t
The number one benefit is obvious: it fits into spaces that can’t accommodate a traditional toilet. If your bathroom has an unused corner or a tricky layout, this could be a perfect solution.
❗ You’ll Need to Plan Plumbing Carefully
Corner toilets often require the drain line and water supply to be precisely located. If your existing plumbing isn’t close to a corner, you may need to reroute pipes, which adds to installation complexity and cost. It’s best to consult a professional before committing.
✅ Comfort and Features Still Matter
Don’t assume you have to sacrifice comfort for compactness. Many corner toilets come in comfort-height versions and include dual-flush functionality to save water. Just make sure to review the dimensions carefully to ensure a good fit for your space.
❗ Style Options Are Fewer
Corner toilets aren't as widely available as standard ones, so you’ll find fewer choices in color, shape, and finish. However, the essentials—efficiency, quality, and modern styling—are still available in most models.
Is a Corner Toilet Right for You?
Here are a few quick ways to determine if a corner toilet could work for your bathroom:
- Your bathroom is under 30 square feet
- You’re renovating an attic, basement, or powder room
- The corner of the room is currently unused
- You want more open space around the toilet or vanity
- You’re open to minor plumbing adjustments during installation
If several of these sound like your situation, a corner toilet could be a great way to optimize space without compromising on performance or aesthetics.
Quick Recap: What You Should Remember
- A corner toilet has a triangular tank designed to fit into the corner of a bathroom.
- It functions like a regular toilet but takes up less wall space.
- Ideal for tight layouts, secondary bathrooms, or unique renovations.
- While installation can be trickier, the space-saving benefits often outweigh the effort.
