Toilet Design

Getting Started Types Design  Flushing Other Considerations

As you choose your toilet, you will want to consider a few details that will have an impact on the overall space as well as ease of use and cleaning. From the footprint to the position of the flush handle, the small details will create the experience you'll have.


Bowl Shapes

Bowl shapes have varying lengths. Knowing what the shape of your toilet bowl is – round, elongated or compact elongated – will be important when you choose a coordinating seat. Round bowls are usually space-saving while elongated offer more comfort for adults.

 

 

ELONGATED TOILETS

 

  • Fits most residential spaces
  • Provides added room and comfort for seating
  • Length from back of tank to nose of bowl - 28-1/2” - 31-5/8”

Browse elongated toilets.

 

 

 

COMPACT ELONGATED TOILETS

 

  • Offers the comfort of an elongated bowl in a round-front toilet footprint
  • Saves up to 10 percent more space than an elongated bowl
  • Length from back of tank to nose of bowl - 26-3/4”- 28-1/2”

Browse compact elongated toilets.

 

 

 

ROUND-FRONT TOILETS

 

  • Requires less space
  • A good solution for small spaces
  • Length from back of tank to nose of bowl - 25-5/8” -29-3/4”

Browse round-front toilets.

 


Seat Heights

Toilet height is measured from the floor to the top of the seat. Heights vary enough to be noticeable. Most often, they fall somewhere between 15” and 19”, with standard toilets coming in under 17”. However, chair height toilets, what Kohler refers to as Comfort Height® toilets, measure 17” or more.

 

 

STANDARD HEIGHT TOILETS

 

  • Ideal for people of average or smaller stature
  • Low-profile

Browse standard height toilets.

 

 

 

CHAIR HEIGHT TOILETS

 

  • Sits at chair height–approximately two inches higher than standard-height toilets
  • Makes standing and sitting easier
  • Many are ADA-compliant when installed per applicable guidelines
  • Comfort Height® is the Kohler term for chair-height toilets

Browse Comfort Height toilets.

 

 

 

CUSTOM HEIGHT TOILETS

 

  • Wall-hung toilets can be positioned at a custom height from 15-3/8" to 28-1/2" to accommodate a range of statures
  • Raised bowl allows cleaning underneath

Browse custom height toilets.

 


Toilet Trapways

The trapway carries waste from the bowl to the piping that leads to your sewer line. Toilets with fully glazed trapways help eliminate clogging. The S-shape of the trapway can be exposed, concealed or completely hidden with a skirted design.

 

 

EXPOSED TRAPWAY TOILETS

Traditionally designed, exposed trapways can be seen from the side of the toilet.

Bolt Caps
Exposed trapway toilets are fitted with standard caps to cover the bolts that attach the toilet to the floor.

Browse exposed trapway toilets.

 

 

CONCEALED TRAPWAY TOILETS

Features a smooth trapway surface that’s easy to wipe clean.

Low-profile bolt caps
Low-profile bolt caps replace traditional raised caps for a smooth, easy-to-clean surface on toilets with concealed trapways. Clean Caps™ is the term Kohler uses for these low-profile bolt caps.

Browse concealed trapway toilets.

 

 

SKIRTED TRAPWAY TOILETS

Offers an easy-to-clean uniform toilet base from front to back.

Clean Installation
No bolts are exposed with a skirted toilet, and many models don’t require drilling, caulk or special tools to install.

Browse skirted trapway toilets.


Toilet Flush Handle Locations

The flush handle location is part of the overall design of the toilet. It can be located as a pull lever or push button on top, as a swing lever on the side or front, as a hidden sensor, or on the wall as a push plate or remote control. You’ll also want to be sure that you have easy access to the handle once the toilet is installed.
