Read Amazon Reviews | See on Kohler

Classy, efficient, and hassle-freethis toilet performs like a dream.

Kohler K-3933-0 Memoirs is one of the classier vintage-looking models. What this means is that the toilet design mimics the sturdy, pristine designs of older models. The notable feature of this toilet is the skirted-based with tier design typical of mid-century toilets. The only difference is that it delivers just like a modern high-efficiency toilet.

How? First of all, the flushing mechanism adequately washes away your waste without clogs or blockages. The reason for this is its flapper-less construction and reliable AquaPiston placement. The flushing system manages to abide by the WaterSense guidelines by keeping the water consumption to a minimum (1.28 GPF).

A comfort height of 17-inches seals the deal for this model. The elevated height is convenient for tall people and senior members of the family. That’s because it makes it easier for them to get on and off the seat compared to standard height toilets that are generally around 15″.

In addition to that, this two-piece model is relatively easy to install. All these things make it a solid investment for your home.


  • Classic design adds an elegant look to your bathroom.
  • Round-bowl to accommodate small bathrooms.
  • Comfort height of 17 inches makes it ideal for the elderly.

Make way for futuristic toilet designs!

The Kohler Veil Toilet is part of the brand’s intelligent series of toilets. The wall-hung model happens to save almost 8-inches of space without dampening your style.

Subsequently, it prevents any mildew and molds from accumulating beneath the toilet.

So to say that the Veil model is a hygiene-inclined toilet is an understatement. That’s because along with this clever construction, it has the vitreous china glaze. The glossy coating makes it look pretty and prevents any dirty skid marks from leaving an impression inside the bowl.

Kohler Numi ―Top Contemporary Toilet


Read Amazon Reviews | See on Kohler

Kohler Numi is everything one would want in a high-tech luxury model. Unsurprisingly, this means that it comes with a hefty price when you bring it home. However, the amazing features do optimize your visits to the washroom.

How? For starters, Numi is a motion-activated toilet that opens and closes according to your movement. You’ve also got a handy remote control that comes with it to help you control its operations. Usually, this would mean selecting the kind of flush you’d want and regulating the water temperature. However, this innovative toilet goes beyond that by introducing music, LED-lightning, and air drying into the mix.

How cool is that? Besides this, you get to select the water pressure and temperature while using the toilet.  These characteristics make it like a toilet-bidet hybrid. The heated seat is also a bonus to its design.

The best part is that despite its over-the-top features, you won’t be let down on its functionality. Numi comes with a dual-flushing system that has an eco-flush (0.8 GPF) and full-flush mode (1.28). So you manage to enjoy this luxury toilet without fretting over the water bill.

The only drawback that we predict for a seat like this is its technical aspects. That’s because it will take you time to understand how it works so be prepared to either hire a professional plumber or rely on their customer support line to help as it is not a job for a beginner DIYer.

A New York article labels Numi as the ‘toilet of tomorrow’.


  • A gorgeous futuristic design fit for a stylish bathroom.
  • High-tech motion-activated features enhance your toilet experience.
  • Dual-flushing functionality (0.8 / 1.28 GPF) caters to your flushing needs.
  • Water-efficient

So let’s begin!

If you’ve got the budget, then try to purchase a toilet that has all of them in it. However, for those of you with a budget, we’ve highlighted the most valuable specs and their benefits.

1. Kohler’s Class Five Flush

Kohler’s Class Five flushing mechanism is the brand’s trademark. The flushing system features cutting-edge technology that’s combined with clever construction. The main purpose of this design is to eliminate clogs and blockages due to an obstruction in the trapway.

It manages to do this by:

  • The rapid-release action of its flush tank puts pressure on the water flow.
  • Big rim hole to make it easier for waste to pass through.
  • A water regulator that consumes a minimum of 1.28 GPF to conserve water.
  • Simple installation process to make the toilet user-friendly.
  • Noiseless flushing to minimize discomfort.
  • Vitreous china coating to reduce sticky residues and bacterial growth.

2. AquaPiston

Are you worried about clogs and blockages?

AquaPiston is an effective way to evade this issue! Upgrade from old-style flapper-valves with this well-crafted fixture, a sturdy canister, and a pressure pump. The piston helps create enough water pressure to assist the gravity-flow of the flushing tank.

Once the flush releases the water, it flows down in a 360-degrees swirling motion. The waterfall-like movement ensures that the water reaches every nook and rim of the toilet bowl before going down.

As a result, you get a cleaner bowl in a single-flush action. Moreover, the secure construction of the piston reduces the chance of leaks and water wastage.

  • In Terms of Hygiene: The brand has a collection of self-cleaning toilet seats that can regulate water pressure, keep you dry, and heat the seat.
  • For Convenience:  They’ve also got a LED-light toilet seat that facilitates your nighttime visits.
