1. Brondell Sutro Integrated Smart Bidet Toilet (IBT-1000)
The Brondell Sutro is the company’s flagship integrated smart bidet toilet, launched in 2024 after two years of development and two decades of bidet expertise.
It’s a fully tankless, one-piece unit designed for nearly hands-free use from start to finish, combining powerful flushing with luxury bidet features in a sleek, contemporary profile.
If you’re comparing this to adding a bidet seat to your existing toilet, the Sutro represents a much more complete, fully integrated solution.

2. Kohler Fora One-Piece Elongated Smart Toilet (K-29149)
The Kohler Fora is a slim, contemporary one-piece smart toilet that brings Kohler’s signature Comfort Height seating and integrated bidet technology together in one of the brand’s most accessible smart toilet designs.
It’s lighter than the Sutro and easier to maneuver during installation, while still delivering a full set of warm-water cleansing features, auto-flush, and hands-free lid operation.
If you’ve previously explored the best bidet brands, you’ll know Kohler brings serious engineering pedigree to everything it makes — and the Fora is no exception.
Features

Pros
- Significantly lighter than the Sutro at 53 lbs — much easier to handle during installation

- No active carbon deodorizer (deodorization is not listed among the Fora’s features)

Flush Performance: Which Toilet Handles Waste Better?
This is where the Brondell Sutro pulls clearly ahead.
The Sutro carries a certified 1000g MaP flush rating — the highest rating available — and achieves this through a dual jet and siphon flushing system that creates a powerful, clog-reducing vortex action on every flush.
The Kohler Fora uses a skirted power-flush design and dual-flush technology, but Kohler has not published a MaP score for the Fora.
If maximum flush power and independent certification matter to you, the Sutro wins this category outright.
Winner: Brondell Sutro
Bidet Features: Which Cleans You Better?
Both toilets offer front and rear warm-water wash, heated seats, warm-air drying, UV nozzle self-cleaning, and remote control operation — so the core bidet experience is strong on both sides.
The Kohler Fora edges ahead in wash customization: its stainless steel wand offers pulsate and oscillate spray modes in addition to standard pressure and temperature adjustments, giving you more control over the nature of the wash itself.
The Brondell Sutro adds a pre-rinse bowl function that mists the bowl interior before use and an active carbon deodorizer that the Fora doesn’t have, which helps with overall bathroom hygiene between cleanings.
For deeper comparison of bidet feature sets across brands, our guide to the best bidets with dryers and bidets with warm water and dryer can help you understand what to prioritize.
Winner: Tie (Fora wins on spray modes; Sutro wins on deodorizer and bowl pre-rinse)
Installation: Which Is Easier to Set Up?
The Kohler Fora is significantly easier to install, weighing just 53 lbs compared to the Sutro’s 99.2 lbs.
Both require a standard 12″ rough-in and a dedicated GFCI outlet (120V, 15A), so the electrical requirements are identical.
The Brondell Sutro uses a no-drill mounting bracket system that simplifies the process, but the sheer weight means you’ll realistically need two people or a professional plumber regardless.
Brondell also enforces a strict limited return policy on the Sutro specifically because of its size and weight — if you measure incorrectly, you may not be able to return it.
The Fora’s lighter build and standard Kohler installation process make it the more DIY-friendly of the two, though professional installation is still recommended for most buyers.
Winner: Kohler Fora
Design and Footprint: Which Fits Your Bathroom Better?
These two toilets are nearly identical in length (26.9″ vs. 26.81″), but the Kohler Fora is noticeably slimmer at 14.56″ wide versus the Sutro’s 15.16″.
The Fora is also taller at 19.56″ vs. the Sutro’s 18.7″, which aligns with Kohler’s Comfort Height specification designed for easier use by adults and those with limited mobility.
Both feature one-piece designs with concealed trapways for easy cleaning, and both are available in white.
If your bathroom has tight side clearances, the Fora’s slimmer width gives it a slight edge.
If you prioritize a standard seat height and slightly lower profile, the Sutro’s lower overall height may suit your bathroom better.
Our guide to the best toilets with bidet covers more integrated options if you want to see how these compare to the wider smart toilet market.
Winner: Tie (Fora is slimmer and Comfort Height; Sutro sits lower)
Hygiene and Self-Cleaning: Which Keeps Itself Cleaner?
Both the Sutro and the Fora include UV nozzle self-cleaning systems and self-cleaning stainless steel wands.
The Brondell Sutro goes further with its pre-rinse bowl function — the bowl automatically wets itself with a fine rinse before every use, preventing waste from sticking to the ceramic.
It also adds an anti-stain ceramic glaze coating and an active carbon deodorizer that runs a 3-minute odor-neutralizing cycle automatically.
The Kohler Fora does not list a pre-rinse bowl function or a carbon deodorizer, so between uses, it relies more on standard cleaning routines.
If bathroom hygiene between cleanings is a priority for your household, the Sutro has a meaningful edge here.
Winner: Brondell Sutro
Verdict: Which Smart Toilet Should You Buy?

Frequently Asked Questions
Do the Brondell Sutro and Kohler Fora require professional installation?
Both require connection to a dedicated 120V, 15A GFCI outlet and a standard 12″ rough-in. While the Kohler Fora’s 53-lb weight makes it more manageable for experienced DIYers, the Brondell Sutro’s 99.2-lb weight makes professional installation strongly advisable. Brondell also enforces a strict limited return policy on the Sutro, so measuring your bathroom precisely before ordering is essential.
Are the Brondell Sutro and Kohler Fora available on major online marketplaces?
Neither the Sutro nor the Fora currently has an active listing on the major online marketplace. Both are sold directly through their manufacturer websites (brondell.com and kohler.com) and through Costco.

Which has better flush power — the Sutro or the Fora?
The Brondell Sutro holds a certified 1000g MaP rating — the highest available — achieved through its dual jet and siphon flushing system. Kohler has not published a MaP score for the Fora. For households that place high value on verified flush performance, the Sutro wins this category.
Do both toilets offer endless warm water for the bidet wash?
The Brondell Sutro uses an instant ceramic water heater that provides continuous, endless warm water for the bidet wash with no cold-water interruption. The Kohler Fora also provides instant warm water, though Kohler does not publish the specific heating technology or tank capacity. Both should deliver comfortable warm-water washes in normal use.
Conclusion
The Brondell Sutro and Kohler Fora are both serious upgrades for anyone ready to invest in a fully integrated smart bidet toilet.
The Sutro leads on flush certification, hygiene automation, and the sheer comprehensiveness of its feature set — it’s the better choice for buyers who want the most complete package and don’t mind the heavier lift at installation time.
The Kohler Fora wins on ease of installation, a slimmer footprint, Comfort Height seating, and richer bidet spray customization — making it the smarter pick if you value manageability and Kohler’s long-term support network.
