If you're working with a small bathroom or planning a tight-space renovation, you may have come across corner toilets as a potential solution. But are they really worth it? In this guide, we’ll break down the pros and cons of corner toilets, helping you decide whether this space-saving fixture is a smart fit—or a compromise in comfort or style.
What Is a Corner Toilet?
A corner toilet is a specially designed toilet with a triangular tank that fits neatly into a corner of the bathroom. Also known as a triangle tank toilet, it’s engineered to make the most of underutilized spaces. The bowl itself usually extends outward like a standard toilet, but the tank's angled shape lets it tuck into corners where a regular toilet might not fit.
The Pros of Corner Toilets
1. Excellent Space Efficiency
Corner toilets are ideal for small bathrooms, powder rooms, or guest suites where every square inch matters. By pushing the tank into the corner, you free up wall and floor space that can be used more effectively.
2. Makes Unused Corners Functional
In many layouts, corners are wasted space. A corner toilet transforms that "dead zone" into a fully functional plumbing fixture, allowing for more flexibility in where you place your sink, shower, or storage.
3. Helps Improve Bathroom Flow
By shifting the toilet out of the direct line of foot traffic, corner toilets can make the room feel more open and navigable—especially in narrow or odd-shaped bathrooms.
4. Sleek and Compact Design
Many modern corner toilets feature minimalist styling that blends well with contemporary interiors. Some models even come with compact bowls or dual-flush systems for added water efficiency.
The Cons of Corner Toilets
1. Limited Selection
Unlike standard toilets, which come in hundreds of shapes and sizes, corner toilets offer fewer choices in terms of style, height, and flushing mechanism. This could make matching your design or plumbing setup more difficult.

2. Higher Cost
Because they are less common, corner toilets tend to cost a bit more—both for the fixture itself and for installation. Expect to pay a premium for quality models or specialized plumbing adjustments.
3. More Complex Installation
Installing a corner toilet often requires adjustments to your water and waste lines, especially in remodels. If your bathroom wasn’t originally designed for one, expect additional labor and cost.
4. Possible Comfort Trade-Offs
Depending on the angle and size of the bathroom, some users find that corner toilets feel a bit cramped, especially if wall clearance is tight. Be sure to check exact dimensions and clearance zones before purchasing.
When Is a Corner Toilet the Right Choice?
Here are a few situations where a corner toilet makes perfect sense:
- Half baths or powder rooms
- Basement bathrooms with awkward layouts
- Converted attics or garages
- Tiny homes, RVs, or mobile units
- Renovations where moving the main drain line isn't feasible
Just remember: venting and drain layout matter. Not all corners are easily plumbed, so consult a contractor or plumber before making the switch.
