Key Differences Between Gerber And KOHLER Toilets

So both Gerber and KOHLER have been producing toilets for a long time. KOHLER tends to focus more on high-design while Gerber is known for value. But how do their actual toilets compare? Let’s dive into the details.

  • Flushing Performance

Arguably the most important feature of any toilet is how well it flushes. You want a toilet that can quickly and completely clear waste with just one flush. Here’s how Gerber and KOHLER models stack up when it comes to flushing power and effectiveness.

Gerber toilets employ a few different flushing mechanisms.

Their dual-flush models utilize a gravity-flush system with a 3″ flush valve that provides substantial siphon action to clear the bowl.

For their single-flush toilets, Gerber uses a combination of gravity flush and a pressurized tank to generate strong flush power.

Most Gerber toilets perform well with only one flush.


KOHLER offers several highly effective toilet flushing systems. Many KOHLER two-piece toilets feature the Class Five flushing technology which makes use of a large 3.25” flush valve, extra-wide trapway, and direct water feed to deliver a fast, clog-free flush.

The Class Six system offers even better performance with sequential flushing action and precision-engineered tanks. KOHLER’s one-piece and dual-flush toilets also provide excellent flushing capability.

Bottom Line

Overall, both Gerber and KOHLER make efficiently flushing toilets. KOHLER’s Class Five and Class Six systems may provide slightly stronger siphon performance, but most models from both brands can clear waste in a single flush. For optimal flushing power, look for KOHLER’s Class Five or Class Six technologies.

  • Bowl Shape and Design

The shape and dimensions of the toilet bowl can impact the flushing effectiveness and comfort of use. Here’s how the bowl designs compare between Gerber and KOHLER.


Most Gerber toilets utilize a standard round-front bowl design. They make some elongated bowl models as well. Gerber bowls typically range from 12-14” in height. The fully-glazed trapway is usually 2-1/8” which helps facilitate thorough waste removal. Overall the bowls are ergonomically-designed for comfort and convenience.

KOHLER offers round-front, elongated, and sleek one-piece bowl options.

Many of the elongated bowls are more angular in shape with squared-off edges rather than oval.

KOHLER bowls are available from standard height to taller, chair height models.

Their AquaPiston canister flush systems make use of a wider 3” trapway for increased flow.

KOHLER bowls come in a range of styles from classic to more contemporary.

Bottom Line

Gerber and KOHLER both utilize thoughtfully designed bowl shapes to maximize flushing power and sitting comfort. KOHLER stands out with its unique rectangular elongated bowls and wide range of height options. But overall either brand offers bowls tailored for optimal performance.

  • Water Efficiency

With environmental impact and utility costs in mind, water efficiency is an important toilet selection factor. Here is how Gerber and KOHLER toilets compare when it comes to water usage.


The majority of Gerber toilet models are WaterSense certified to use 1.28 gpf (gallons per flush) or less. Their dual flush toilets operate at 1.1 gpf for the light flush and 1.6 gpf for a full flush. Gerber offers some older 3.5 gpf models but most are 1.6 gpf or better. Overall Gerber toilets are reasonably efficient with most meeting EPA WaterSense standards.


Nearly all KOHLER toilets are EPA WaterSense certified high-efficiency models using 1.28 gpf or less. Their dual flush designs allow for a light 0.8-1.1 gpf flush and a full 1.6 gpf flush. KOHLER also produces some ultra low-flow toilets rated at just 1.0 gpf. When it comes to water conservation, KOHLER sets the bar high with their wide selection of low-flow models.

Bottom Line

Both Gerber and KOHLER offer numerous water-efficient 1.28 gpf toilet options. KOHLER edges out with more ultra-low 1.0 gpf models but most toilets from both brands utilize 1.28 gpf or less. Either brand is a good choice for water conservation.

  • Comfort Height Bowls

Comfort height (also known as chair height) toilets have risen in popularity in recent years. The higher seat height between 17-19” makes sitting down and standing up easier for most adult users. Here are some details on comfort height models from Gerber and KOHLER.


Gerber Maxwell Toilet

Gerber produces a few different toilets with comfort height bowls.

Their Maxwell line includes elongated bowl models between 17-19” in height.

Some of Gerber’s AquaSense one-piece toilets also feature chair height designs.

Overall Gerber has a decent comfort height selection but more limited compared to other brands.


KOHLER has embraced the comfort height trend and offers many models in 17-19” heights. Their Cimarron, Tresham, and Wellworth collections include several comfort height options in round and elongated bowls. KOHLER also produces chair height one-piece toilets like the Archer and the Reach II. KOHLER’s range of comfort height models accommodates users of all ages and abilities.

Bottom Line

For the widest selection of elongated bowl comfort height toilets, KOHLER is the winner. But Gerber does produce some very functional chair height models like the Maxwell. Just note Gerber’s comfort height offerings are more limited.

  • Ease of Installation

Installing a new toilet involves some work. Here’s a look at some of the features and factors that can make Gerber and KOHLER toilets easier (or more difficult) to install.


Gerber toilets come with simple, straightforward installation instructions. The bolt caps for floor mounting the bowl are integrated into the base for no lost parts. Gerber toilet tanks are designed for quick and secure mounting on the bowl. Installation is further simplified with a pre-installed tank-to-bowl gasket. Overall Gerber toilets go in with minimal fuss.

KOHLER also strives for quick installation and no-hassle maintenance in their toilet designs.

Their ReadyLock system allows the tank to easily slide into place and lock onto the bowl using just 4 pre-installed bolts.

KOHLER also employs shank gaskets and seals that don’t require wax rings or caulking.

Like Gerber, KOHLER includes clear instructions and all parts needed for DIY installation.

Bottom Line

Gerber and KOHLER both design their toilets for straightforward installation. Quick-mount tank systems and integrated gaskets help make the installation process smooth and simple for either brand. For most basic toilet installations, there is minimal difference in the process between the two brands.

  • Warranties

Toilet warranties provide peace of mind in case any defects occur. Here is how the warranties compare between Gerber and KOHLER.


Gerber offers a solid limited lifetime warranty on their vitreous china toilets. This covers defects in materials and workmanship for as long as you own the toilet. Wear-and-tear coverage is limited to 5 years. Gerber toilet tank parts have 3-10 year warranties while toilet seats are 1 year. Overall good coverage from Gerber.


KOHLER stands out with exceptional toilet warranties. Their one and two-piece toilets have a lifetime limited warranty covering the porcelain components against defects, peeling, and fading. The AquaPiston canister mechanisms have a 5 year warranty. All other KOHLER toilet parts are covered for 3 years after install. These comprehensive warranties provide great long-term protection.

Bottom Line

While both brands offer solid toilet warranties, KOHLER is ahead here. Their lifetime warranties on the vitreous components beat out Gerber’s lifetime functionality coverage. KOHLER also provides longer 3 year parts warranties compared to Gerber’s 1-10 years depending on the part.

  • Pricing Differences

Let’s compare the typical pricing you can expect to pay for Gerber and KOHLER toilet models.

Across their toilet range, Gerber’s list prices start around $100 for basic budget models and top out around $570 for higher-end two-piece toilets with comfort height bowls and dual flush.

The average list price for most popular Gerber models falls in the $150 to $350 range.

Being a value brand, Gerber offers very attractive pricing.


KOHLER toilets have list prices starting around $160 for entry-level small bath models up to $1,500+ for designer one-piece toilets with unique styling. However, many popular KOHLER models fall in the moderate $300 to $600 range. While not the cheapest, KOHLER’s pricing reflects their quality construction and reputation.

Bottom Line

Gerber consistently prices their toilets lower than KOHLER across comparable models. However, KOHLER frequently offers rebates and sales that help offset the pricing gap. Ultimately Gerber offers great value while KOHLER provides quality backed by strong warranties.
