2 Top 18 Inch High Toilets with 18 Inch Toilet Bowl Height

When I searched Google for ’18 inch high toilets’ or ’18 inch toilet bowl height’ I found many matching search results. But when I checked those search result pages, the toilet models they contained were 16.5″ or 17 inch high toilets that could be made into 18 inch high toilets with a thick raised toilet seat or some other trick.

So I tried to find one and finally after much research came across only one toilet model that can be called a 18 inch high toilet with an 18 inch high toilet bowl. I’d like to share my findings with you here. Below are the details about that toilet model.

The price of this toilet is also very reasonable. Considering its unique feature of 18 inch high toilet bowl rim I think many people would have bought this toilet even if it was double its price. Specially considering there are lot of people wanting to buy 18 inch toilets. And only few other toilet models that can be made into a 18 inch high toilet even with a trick like an extra-high raised seat .

It’s also nice that it comes with a seat included. Normally with most toilets these days you have to buy a toilet seat separately which cost additional to you.

KOHLER 18 Inch Toilet

While looking into 18″ toilets I saw many mentions of Kohler 18 inch toilet but I couldn’t find any Kohler toilet with a 18 inch high toilet bowl. However I found a Kohler toilet model that has a 17 1/8″ inch high bowl rim height. Depending on the toilet seat you use, its height with seat increases to between 18 to 18 1/2 inches. Below is that toilet
