Corner Toilet Dimensions To Consider

As modern lifestyles shift towards minimalist living, small bathrooms are increasingly becoming common. If you’re not endowed with an ample barroom space, you may need to consider installing a corner toilet to free up room for a vanity or other crucial bathroom accessories. Understanding corner toilet dimensions will ensure that you eliminate the need to break up a wall or remove a closet to create space for your toilet unit.

What is a Corner Toilet?

As the name suggests, a corner toilet, sometimes referred to as a space-saving toilet, is installed in the corner of a bathroom instead of against a flat wall as regular toilets would be. The bowl of the toilet looks and functions just like a regular toilet system, but the water tank is specially shaped into a triangle shape to tuck into a corner easily.

So, if you have a significantly smaller bathroom and looking for a means to maximize the space, a corner toilet could be the perfect solution.

Corner Toilet Dimensions

There are two essential dimensions to consider when choosing a corner toilet system: technical dimensions and room dimensions.

1: Technical Dimensions 

Technical dimensions refer to the ‘rough in’ dimensions required for the toilet. You must ensure that the positioning of the toilet drain is enough to account for the ‘rough in’ measurements of the toilet unit you’re purchasing. Although it’s possible to move a toilet drain, it’s something you want to avoid at all costs due to the strenuous and costly floor-breaking and plumbing work involved.

2: Room Dimensions 

Room dimensions refer to how much floor space the toilet unit will take up in the bathroom. While corner toilets are extremely space-saving, not all units will fit in all small bathrooms. Measure how far the toilet system will jut out from the corner and whether any cabinets or doors might be in the way.

How To Measure A Corner Toilet Rough In 

To determine the rough-in of a corner toilet, measure and mark the rough-in length out from each adjacent wall. Just like regular toilets, most corner toilets have a 12″ rough-in. Use a straight edge to mark two perpendicular lines running from the marks you created in the previous step. If it measures 12″ from the framing both ways, that is the rough-in measurement of the toilet. On rare occasions, you might find a corner toilet with a rough of 10 inches.

Depending on whether you have extra tiling on the bathroom wall, you may need to move the flange before installing your corner toilet. If your wall’s thickness increases by more than 1/2 inch, then you probably need to move the flanges. Since the 1/2 inch will be from both adjacent walls, it means that the distance from the corner would be about 17 inches. Alternatively, you can opt for a 10-inch rough-in toilet if you don’t wish to move the flanges.

Wrapping Up

Overall, corner toilets can help you maximize space in your small bathroom. Just be sure to take your measurements right and ensure that your toilet unit is at least 15 inches from the center of the toilet to the side of any wall or obstruction and not closer than 30 inches to other sanitary fixtures.

FAQs: 

How much space do you need for a corner toilet?

Most plumbing codes require a corner toilet to be installed at least 15 inches from the center of the toilet unit to any side wall or obstruction (such as cabinets) and not closer than 30 inches to any other sanitary fixture (measured center to center). There should be at least 24 inches of clear space in front of your toilet or bidet.

Does a corner toilet save space?

Yes! Corner toilets typically come with a smaller, round bowl, and the tank and is shaped like a triangle to snugly fit into the corner of the bathroom – space that is ordinarily wasted. Besides, you won’t require a lot of plumbing systems to install a corner toilet.

Can you put a standard toilet in a corner?

You can frame the corner of your bathroom and install a standard toilet if you prefer. However, one benefit of installing a corner toilet is that it won’t protrude into the bathroom space as far as framing a flat surface and using a non-corner toilet.
