Some people don’t have a luxurious bathroom like me, live in a small house with a small bathroom. It is not difficult to design your bathroom with a small toilet. Tell me one thing, are you a fan of Kohler and looking for the best Kohler toilet for a small bathroom?

There are lots of factors you have to check before buying the best compact toilet. The most important thing is you must have at least 30-inch space from the wall.

If you have that space, then you are welcome to our small size toilet room. The size of our Kohler toilet

I saw some people tearing down the entire bathroom and rebuilding it from the ground up. This is not a wise decision in my opinion.

Suppose you examine your bathroom and think of purchasing a small, one-piece, or two-piece toilet with the least amount of rough-in. This is the best option when dealing with a small restroom.

In the market, lots of compact toilets are present like Toto, American Standard, and Kohler.

We appreciate Kohler’s functionality and quality, so we’ve decided to review the best Kohler toilet for a small bathroom.

In this article, I’ve chosen the best three Kohler models ideal for a tiny home.

If you’re in a rush, then here is our quick tour:

Check it out if you’re on a tight budget but want a small toilet.  I believe it is worthwhile to purchase.

Check the things before buying a toilet for small bathrooms

Purchasing a toilet is not a big deal, but selecting a high-quality toilet is. So, how do you know the toilet is appropriate for your small bathroom? 

Here is our step-by-step guide to resolving your issue. 

The below-mentioned factors must be considered before purchasing.

1.Rough-in size:

Most of the buyers make a common mistake that is rough-in. If you install a new commode, always go with a small rough-in, preferable for a small washroom.

If you want to replace the old one, measure the rough-in and buy according to your measurement.

In the market, mainly three types of rough-in are available. Those are 10, 12, and 14 inches. The standard one is 12 inches.

2.One-piece vs two-piece:

The tank and pot of a two-piece toilet are sold separately. We prefer a two-piece toilet because it is less expensive. 

In comparison to a single piece, it requires more space. The tank and bowls of a one-piece toilet are joined. That is why it takes up less space than a two-piece.

Don’t forget to check our One-piece toilet VS two-piece toilet complete guide.

3.Round vs Elongated:

The round bowl is smaller than an elongated one, but the elongated bowl is more comfortable.

If you like elongated bowls, don’t worry because Kohler also makes a smaller elongated bowl that fits in the same place as a round one.

It is entirely up to you to make your selection..Still confused! Check Round Toilet VS Elongated and make your decision.


We all know smaller dimensions are best for any small space.

I want to share a short story that happened to me: I looked for a small toilet and came across a well-designed product while researching.

I was so impressed with the design that I missed double-checking the measurements. Finally, due to the dimensions, I return it. As usual, it won’t fit in my teeny-tiny bathroom.

5.Flushing mechanism:

The flushing power of a small toilet is not the most important factor to consider. Indirectly it can affect your purchase because not only a tiny toilet is good enough for your bathroom, the performance also matters.

As a result, always choose a high-power flushing system that is available in a compact toilet.

So, these are the critical points to double-check before investing.

Okay, so you now have a clear idea of what a space-saving toilet is.
