Best Square and Modern Toilets of 2026

A square toilet is a design statement first and a fixture second. The squared-off tank, the crisp 90-degree edges and the skirted, trapway-hiding base read as architectural rather than utilitarian, which is why squared and angular bowls have become the signature of the modern bathroom. The catch is that a sharp silhouette tells you nothing about how the toilet flushes. We ranked the best square and modern toilets by published MaP flush-test scores, EPA WaterSense certification, gallons per flush, trapway design and the patterns across thousands of aggregated owner reviews, then weighted how cleanly each one delivers that contemporary look without trading away flush power, water efficiency or serviceable parts.

Why Trust Best Flushing Toilets

  • Flushing power and MaP flush-test scores
  • Water efficiency (GPF and EPA WaterSense)
  • Aggregated owner reviews
  • Clog resistance and trapway design
  • Brand reliability and warranty

Research updated June 2026.

Quick Answer

The TOTO Aquia IV is the best square and modern toilet, because its skirted, squared one-box silhouette pairs the contemporary look people want with a perfect 1,000-gram MaP flush, dual-flush water savings at 0.8 and 1.28 gallons, and TOTO parts support. For a true geometric tank choose the Swiss Madison St. Tropez, and for the cleanest seamless cube look pick the Kohler Veil or Woodbridge T-0019.

Square and modern toilets answer a question the traditional toilet market mostly ignores: how the fixture looks in a contemporary bathroom. For decades a toilet was a rounded, two-piece object with an exposed trapway and a tank-to-bowl seam, designed to disappear rather than to be looked at. The modern category flips that. A square toilet squares off the tank corners and often the bowl rim, a skirted toilet wraps a smooth panel over the contoured trapway so the base reads as a single clean shape, and a low-profile one-piece collapses the tank and bowl into one seamless cube. The result is a fixture that belongs in a room of straight lines, flat-panel vanities and large-format tile, where a rounded traditional toilet would look out of place.

We do not install or test these toilets ourselves. Instead we compare published manufacturer dimensions, independent MaP (Maximum Performance) flush-test scores, EPA WaterSense certification and the patterns across thousands of verified owner reviews. The modern category is unusual in that styling is doing a lot of the selling, and a sleek body can hide a weak flush, a hard-to-source flush mechanism or a bowl that smears. So this roundup does two things at once: it ranks the toilets that actually deliver the squared, skirted, contemporary look people are shopping for, and it filters out the ones where the look comes at the cost of a flush that needs a second pull. For every pick we asked the same questions: does it genuinely read as modern, does it clear the bowl in one flush, does it stay clean, and are the parts something a plumber can replace. For the full performance-first ranking across every style, start with our guide to the best flushing toilets.

What Is the Best Square or Modern Toilet?

The best square and modern toilet for most bathrooms is the TOTO Aquia IV, because its skirted, squared one-box silhouette delivers a genuinely contemporary look while still posting a perfect 1,000-gram MaP flush, dual-flush efficiency at 0.8 and 1.28 gallons and reliable TOTO parts support. For a true geometric tank, the Swiss Madison St. Tropez is the value pick, while the Kohler Veil and Woodbridge T-0019 give the cleanest seamless cube look for a fully modern room.

How We Research and Rank Square and Modern Toilets

The modern category is the one where styling is most likely to outrun substance, so the bar for inclusion balances looks against the numbers. A pick earns a place by reading as genuinely contemporary, which means a squared tank, a skirted trapway-hiding base, a low one-piece profile or a combination of those, not just a marketing label. From there we judged every candidate on the same metrics as any toilet: MaP flush score, where 350 grams is the residential pass threshold and 600 grams or higher is considered strong; EPA WaterSense certification and a 1.28-gallons-per-flush rating or better; trapway width and glazing for clog resistance; and the patterns across aggregated owner reviews on flush reliability, leaks, bowl streaking and parts availability. Because skirted and one-piece bodies are chosen partly to make cleaning easier, we weighted easy-clean geometry and a fully glazed bowl heavily, and we paid close attention to the flush mechanism, since many boutique modern brands use proprietary valves that are harder to replace. We weighted verifiable specs and aggregated owner feedback over marketing language, and we do not take payment for placement. The table below summarizes how the picks compare on the numbers that decide whether a modern toilet is worth living with.

The 9 Best Square and Modern Toilets, Reviewed

TOTO Aquia IV toilet
1
Best Square and Modern Overall

TOTO Aquia IV

4.6 Skirted modern look

The Aquia IV is the modern toilet we recommend to most shoppers, because its skirted, squared-off body delivers the clean contemporary silhouette people are actually buying without the weak flush or orphaned parts that plague boutique brands chasing the same look.

Flush TypeDual flush, gravity
GPF0.8 / 1.28
MaP Score1,000 grams
Bowl HeightComfort (17.25 in)
Warranty1-year limited
Best For
  • A skirted, squared modern bathroom
  • Cutting water use with dual flush
  • Wiping the body clean in one pass
Not Ideal For
  • Buyers who want the seat in the box
  • The tightest rough-in depths

The skirted base encloses the contoured trapway behind a smooth side panel, so the toilet reads as one crisp shape rather than a lumpy traditional fixture, and the low one-box tank keeps the silhouette flat and architectural. TOTO's CeFiONtect glaze keeps the bowl from streaking between cleanings, while the dual flush pairs a 0.8-gallon liquid flush with a 1.28-gallon full flush that earns EPA WaterSense certification and a perfect 1,000-gram MaP score.

Owners consistently report that it clears the bowl in a single flush, which is not a given on water-saving dual-flush designs, and praise how little the skirted shape needs scrubbing. The seat sells separately, and the elongated bowl wants a little more depth than a round front, so confirm your open floor space and budget for the matching SoftClose seat. For the full short-body picture, see our guide to the best toilets for small bathrooms.

Expert Take

If you want the modern, skirted look but refuse to gamble on flush power or parts, this is the one to buy. The perfect 1,000-gram MaP score and CeFiONtect glaze put it ahead of nearly every style-first competitor, and TOTO parts are something any plumbing aisle can match, so a fill valve failure never strands the toilet.

Check price on Amazon
Bottom Line: The best square and modern toilet overall, pairing a skirted contemporary body with a reliable, water-smart 1,000-gram flush.
Swiss Madison St. Tropez toilet
2
Best Geometric Tank Value

Swiss Madison St. Tropez

4.4 Modern on a budget

The St. Tropez is the value choice when you want a true geometric, squared modern tank and the major-brand one-pieces stretch the budget, offering a sharply styled skirted one-piece with a dual-flush button at a far lower outlay.

Flush TypeDual flush, gravity
GPF0.8 / 1.28
MaP Score600 grams
Bowl HeightComfort (17 in)
Warranty1-year limited
Best For
  • A design-led powder room
  • Saving water with dual flush
  • Wiping down a skirted body fast
Not Ideal For
  • Heavy-use family bathrooms
  • Owners who want easy local parts

The skirted, squared base hides the trapway and wipes clean in one stroke, while the low integrated tank keeps the body flat against the wall for that one-shape modern look. The dual flush gives a light 0.8-gallon flush for liquids and a 1.28-gallon full flush for solids, adding up to meaningful water savings in a bath that sees frequent light use.

Its 600-gram MaP score sits below the power picks, so it suits a low-to-moderate-traffic bath rather than a heavy-use family bathroom. Owners praise the contemporary styling and the price, but as with most boutique brands, the proprietary flush valve and matching seat can be harder to source, so confirm parts availability before you order.

Expert Take

Choose this when looks matter as much as function in a guest or low-traffic modern bath. It is one of the better-looking budget options here, just match it to lighter use so the moderate 600-gram MaP score never becomes a problem, and buy a spare fill valve up front since boutique parts can be slow to find.

Check price on Amazon
Bottom Line: The best value geometric modern toilet, ideal for a design-led powder room where the squared skirted look earns its place.
Kohler Veil toilet
3
Best Seamless Cube Look

Kohler Veil

4.5 Architectural one-piece

The Veil is the seamless modern statement piece on this list, a low, skirted one-piece with a near-cube silhouette and a concealed dual-flush actuator that gives it the cleanest, most architectural shape of any pick here.

Flush TypeDual flush, gravity
GPF0.8 / 1.28
MaP Score800 grams
Bowl HeightComfort (16.5 in)
Warranty1-year limited
Best For
  • A fully modern, minimalist room
  • Owners who hate visible flush buttons
  • A seamless, easy-to-wipe body
Not Ideal For
  • Solo DIY installs (it is heavy)
  • The tightest budgets

The fully skirted one-piece body has no tank-to-bowl seam and no visible flush handle, with the dual-flush actuator integrated into the top of the tank, so the toilet reads as a single low cube. Kohler's gravity flush moves a strong, wide rinse that owners rate highly for single-flush reliability, and the glazed bowl resists streaking, which keeps the minimalist look looking clean.

Reviewers consistently praise how striking and contemporary the shape is and how little upkeep the seamless lines demand. The one-piece body is heavy to maneuver and costs more than a comparable two-piece, so plan the install with a second pair of hands, and note that the integrated actuator is a Kohler-specific part to keep in mind for the long term.

Expert Take

For a truly modern, minimalist bathroom where the toilet is meant to be seen, the Veil is the standout shape. The seamless cube body is worth the extra lift on installation day, and unlike many style-first toilets it backs the look with a genuine 800-gram flush and Kohler parts support rather than a boutique-brand gamble.

Check price on Amazon
Bottom Line: The most architectural modern pick, a seamless cube one-piece that backs its striking look with a strong, reliable flush.
Woodbridge T-0019 toilet
4
Best Modern One-Piece Value

Woodbridge T-0019

4.4 Premium look, less money

The Woodbridge T-0019 brings a high-end modern one-piece look to a bathroom for far less than the premium brands, with a smooth skirted body, squared lines and a soft-close seat included in the box.

Flush TypeDual flush, siphon
GPF1.0 / 1.6
MaP Score800 grams
Bowl HeightComfort (16.5 in)
Warranty5-year (porcelain)
Best For
  • A premium modern look on a budget
  • A seamless, easy-to-wipe skirted body
  • Owners who want the seat included
Not Ideal For
  • Strict low-flow households (1.6 GPF full)
  • Buyers who want big-box parts

The fully skirted base hides the trapway and the one-piece body wipes down in a single stroke, while the included soft-close seat and the squared, contemporary lines deliver a designer look without the designer outlay. The siphon dual-flush system runs quietly, which owners single out in modern open-plan homes where the bath sits close to living space.

Its full flush uses 1.6 gallons rather than 1.28, so it is slightly less efficient than the WaterSense leaders, but the 800-gram MaP score and seamless styling make it a strong value alternative to a Kohler or TOTO one-piece. As with most direct-to-consumer brands, parts come from the manufacturer rather than a local store, so keep that in mind for long-term service. If quiet operation is a priority, see our guide to the best quiet flush toilets.

Expert Take

If you love the seamless modern look of the Veil but want to spend less and get a seat in the box, the T-0019 is the value route. Just note the 1.6-gallon full flush if water efficiency is a strict priority, since it sits outside the WaterSense range, and order a spare flush valve so a future repair is painless.

Check price on Amazon
Bottom Line: A skirted, modern one-piece with a soft-close seat included that brings premium styling at a mid-range price.
Kohler Memoirs Stately toilet
5
Best Architectural Classic-Modern

Kohler Memoirs Stately

4.5 Squared traditional lines

The Memoirs Stately is the toilet for a modern bathroom that wants squared, architectural lines without going fully minimalist, a two-piece with a crisp rectangular tank and a strong 1,000-gram flush behind the looks.

Flush TypeSingle, gravity
GPF1.28
MaP Score1000 grams
Bowl HeightComfort (16.5 in)
Warranty1-year limited
Best For
  • A transitional or architectural bath
  • A strong single flush behind clean lines
  • Squared styling without minimalism
Not Ideal For
  • Fully minimalist skirted rooms
  • The tightest budgets

The Stately trim gives the Memoirs a squared, paneled tank with crisp vertical lines that read as architectural rather than rounded, so it suits a transitional or detail-rich modern bath where a plain skirted cube would feel too stark. Behind the looks, Kohler's gravity flush posts a top-tier 1,000-gram MaP score, so the styling never costs you flush power.

Owners praise the substantial, high-end feel and the dependable single-flush performance, a strong combination for a primary bath. The trapway is exposed in two-piece form, so this is the modern pick for shoppers who prioritize squared character and flush strength over a fully hidden, seamless base.

Expert Take

Not every modern bathroom wants a featureless cube. If your room leans transitional or architectural, the Memoirs Stately gives you squared, paneled character with a genuine 1,000-gram flush, which is the best flush power on this list. Pair it with a squared seat and matching trim to complete the look.

Check price on Amazon
Bottom Line: The best squared architectural pick, pairing crisp rectangular styling with a top-tier 1,000-gram flush.
TOTO Vespin II toilet
6
Best Skirted Power Flush

TOTO Vespin II

4.6 Modern look, max flush

The Vespin II is the skirted modern toilet for shoppers who refuse to compromise on flush power, marrying TOTO's clean concealed-trapway styling with a maximum 1,000-gram MaP score and the powerful Double Cyclone flush.

Flush TypeSingle, Double Cyclone
GPF1.28
MaP Score1000 grams
Bowl HeightComfort (17.25 in)

Best For
  • A modern bath that sees heavy use
  • A skirted look with maximum flush power
  • Stain-resistant, easy-clean glazing
Not Ideal For
  • The tightest budgets
  • Buyers who want dual flush

The skirted two-piece body conceals the trapway behind a smooth side panel, so it delivers the clean modern look in a single-flush package that matches the dual-flush Aquia IV on raw MaP score. TOTO's Double Cyclone system uses two nozzles instead of rim holes to drive a strong, efficient rinse at just 1.28 gallons, and the CeFiONtect glaze keeps the bowl clean, earning a maximum 1,000-gram MaP score.

Owners report it clears heavy loads in a single flush and stays clean with minimal scrubbing, making it the modern pick for a busy primary or family bathroom rather than a low-traffic powder room. It is a single-flush design, so if dual-flush water savings matter more than a simpler single-flush valve, the Aquia IV is the better match, since it hits the same 1,000-gram ceiling. For the strongest options across all styles, see our guide to the best flushing toilets.

Expert Take

If you want the skirted modern look but the toilet has to handle a busy household, the Vespin II is a great pick. You get the same concealed-trapway styling and the same maximum 1,000-gram flush as the dual-flush Aquia IV, just with the efficient single-flush Double Cyclone system instead of a dual-flush button, which is the best combination of modern looks and raw power here.

Check price on Amazon
Bottom Line: The best skirted modern toilet for heavy use, combining concealed-trapway styling with a maximum 1,000-gram flush.
Kohler Highline toilet
7
Best Modern Workhorse

Kohler Highline

4.5 Clean lines, low cost

The Highline is the value modern workhorse, a clean-lined two-piece with a simple, contemporary tank profile and a strong 1,000-gram flush that fits a modern bath without the premium price of a skirted one-piece.

Flush TypeSingle, Class Five
GPF1.28
MaP Score1000 grams
Bowl HeightComfort (16.5 in)
Warranty1-year limited
Best For
  • A clean modern look on a budget
  • A strong, dependable single flush
  • Easy servicing with common parts
Not Ideal For
  • Fully skirted, seamless rooms
  • Owners who want dual flush

The Highline keeps the look simple and uncluttered with smooth, straight tank lines that suit a modern room without trying to be a statement piece. Kohler's Class Five flushing system moves a strong, wide rinse that posts a 1,000-gram MaP score, and the design is one of the most widely stocked toilets in the country, so parts are everywhere.

Owners rate it highly for dependable single-flush performance and value, which is why it is a default recommendation for a clean, no-drama modern upgrade. The trapway is exposed, so it lacks the seamless skirted look of the pricier picks, but as an affordable, reliable modern workhorse it is hard to beat.

Expert Take

When you want a modern, uncluttered look without paying for a skirted one-piece, the Highline is the smart-money choice. You get a 1,000-gram Class Five flush and parts any plumber stocks, which makes it the easiest modern toilet to live with and service over the long term.

Check price on Amazon
Bottom Line: The best value modern workhorse, pairing clean contemporary lines with a strong 1,000-gram flush and easy parts.
Swiss Madison Sublime toilet
8
Best Wall-Hung Modern

Swiss Madison Sublime

4.3 Floating fixture look

The Sublime is the modern pick for shoppers who want the floating, wall-hung look, a squared bowl mounted on a concealed in-wall tank that frees the floor beneath it for the most minimalist install on this list.

Flush TypeDual flush, gravity
GPF0.8 / 1.28
MaP Score600 grams
Bowl HeightAdjustable (set at install)
Warranty1-year limited
Best For
  • A floating, ultra-modern look
  • Easy floor cleaning underneath
  • Setting a custom seat height
Not Ideal For
  • Simple drop-in replacements
  • Heavy-use family bathrooms

The wall-hung design mounts the bowl on a steel carrier frame and conceals the tank inside the wall, leaving only a flush plate visible and the floor beneath the bowl open, which is the most space-saving and contemporary look available. The squared bowl and dual flush keep both the styling and the water use modern, and being able to set the mounting height lets you dial in seat comfort.

Owners love the floating look and the easy-to-clean floor, but a wall-hung toilet is a bigger project: it needs an in-wall carrier and enough wall depth, so it is best planned into a remodel rather than dropped in as a swap. The 600-gram MaP score suits moderate use, and the concealed tank means servicing happens behind an access panel, so factor that into the decision. For more on this style, see our guide to the best wall-hung toilets.

Expert Take

A wall-hung toilet is the most modern look you can install, and the Sublime is an accessible way into it. Just go in knowing it is a remodel-level project, not a swap: you need the in-wall carrier and wall depth, and you should confirm the flush plate and valve are serviceable through the access panel before you close up the wall.

Check price on Amazon
Bottom Line: The most minimalist modern option, a floating wall-hung toilet best planned into a remodel for its concealed in-wall tank.
TOTO Drake II toilet

Best Clean-Lined Two-Piece

TOTO Drake II

4.6 Low-profile reliability

The Drake II is the clean-lined two-piece for a modern bath that values flush reliability above a fully skirted look, with a low, smooth tank profile and TOTO's efficient Double Cyclone flush.

Flush TypeSingle, Double Cyclone
GPF1.28
MaP Score1,000 g

Best For
  • A clean, low-profile modern look
  • Reliable single-flush performance
  • Stain-resistant, easy-clean glazing
Not Ideal For
  • Fully skirted, seamless rooms
  • Owners who want dual flush

The Drake II updates the classic Drake with a lower, more contemporary tank that smooths out the older model's boxy silhouette, giving a clean modern look without the cost of a skirted one-piece. The Double Cyclone flush uses two nozzles for a strong, efficient rinse at 1.28 gallons, and the CeFiONtect glaze keeps the bowl clean, earning a solid 800-gram MaP score.

Owners consistently rate it among the most reliable toilets they have owned, with dependable single-flush performance and minimal cleaning. The trapway is exposed, so it is not a seamless skirted pick, but for a modern bath that wants proven TOTO reliability in a clean low-profile body, it is one of the safest choices here. For more reliable daily-use options, see our guide to the most reliable toilets for daily use.

Expert Take

If you want TOTO reliability and a clean modern profile but do not need a skirted base, the Drake II is the value-smart choice. The lower tank reads as more contemporary than the original Drake, and the Double Cyclone flush gives you proven performance at an efficient 1.28 gallons.

Check price on Amazon
Bottom Line: The best clean-lined modern two-piece, pairing a low contemporary tank with proven TOTO single-flush reliability.
Expert Take

Across all nine picks, the pattern is clear. A modern look and a strong flush are not in conflict, but only if you choose carefully, because the styling that sells these toilets can mask a weak flush or a hard-to-replace mechanism. The TOTO Aquia IV stands out because it nails the skirted contemporary look while posting a perfect 1,000-gram MaP flush, dual-flush efficiency and real parts support. If budget rules, the Highline and St. Tropez deliver the look for less; and if you are remodeling, the wall-hung Sublime is the most minimalist statement you can install. Confirm your rough-in, decide how much you value a seamless skirted base versus a dual-flush button, and prefer a major brand whose flush valve any plumber can source.

Do Square Toilets Flush as Well as Round Ones?

Yes, a square or modern toilet can flush just as well as a traditional rounded one, because flush power comes from bowl geometry, trapway size and the flush valve, not the shape of the tank or rim. The TOTO Vespin II and Kohler Memoirs Stately both post a maximum 1,000-gram MaP score in squared or skirted modern bodies. The key is to check the published MaP score rather than assuming a sleek shape flushes weakly, since some style-first boutique models do trade away power.

How to Choose a Square or Modern Toilet

Buying a modern toilet is really an exercise in seeing past the photo to the spec sheet, because the styling that makes these toilets appealing is also where corners get cut. The checks below cover the mistakes that lead to a return, or to a beautiful toilet that flushes twice or cannot be serviced.

Match the style of modern to your bathroom

Modern is not one look. A squared, paneled tank like the Memoirs Stately suits a transitional or architectural room, a skirted body like the Aquia IV or Vespin II suits a clean contemporary bath, a seamless one-piece cube like the Veil suits a minimalist room, and a wall-hung bowl like the Sublime suits a high-design remodel. Decide which of these your room actually calls for before you shop, because they differ enormously in installation effort and price even though they all wear the modern label. A skirted two-piece gives most of the look of a one-piece for less money and weight, which is the sweet spot for many shoppers.

Do not let styling hide a weak flush

The single biggest mistake in this category is buying on looks alone and ending up with a toilet that needs a second flush. Many boutique modern brands post MaP scores of only 350 to 500 grams, which clears the residential pass but leaves little margin. Flush power comes from bowl geometry, trapway size and the flush valve, so check the MaP score directly: aim for at least 600 grams in a low-traffic powder room and 800 grams or more in a bath that sees daily use. The Aquia IV, Veil, Vespin II, Highline and Memoirs Stately all clear that bar, while some style-first competitors do not.

Check the flush mechanism and parts before you buy a modern toilet. Skirted and one-piece modern toilets, and especially boutique brands, often use proprietary fill valves, flush valves and top-mounted dual-flush actuators that big-box stores do not stock. A common fill valve failure on an off-brand modern unit can leave the toilet out of service while you wait on a manufacturer part. Favor a major brand like TOTO, Kohler or American Standard whose mechanisms a plumber can match, or order a spare valve up front so a simple repair never strands you.

Plan installation around skirted, one-piece and wall-hung bodies

Modern bodies install differently than a basic two-piece. Skirted toilets often mount to the floor with a concealed bracket system rather than standard bolt caps, so read the instructions before you start. One-piece toilets like the Veil are heavy and best lifted into place with a second person. Wall-hung toilets like the Sublime are a different project entirely, requiring an in-wall carrier frame and enough wall depth, which makes them a remodel decision rather than a swap. Confirm your rough-in, your floor and wall structure, and whether the seat is included before you commit, since many modern picks sell the seat separately.

Expert Take

Resist the urge to choose by the photo alone. In the modern category, the order of operations is the look that fits your room, then flush power at an 800-gram or higher MaP score, then a serviceable flush mechanism, and only then the price. A skirted two-piece from a major brand like the Aquia IV or Vespin II is the safest sweet spot, giving you nearly all of the seamless look with proven flush power and parts you can actually replace.

What Is a Good MaP Score for a Modern Toilet?

A good MaP score for a square or modern toilet is 600 grams or higher, with 800 to 1,000 grams considered strong. MaP testing measures how many grams of solid waste a toilet clears in a single flush, and 350 grams is the minimum residential pass. Because style-first modern brands sometimes trade flush power for looks, aim for at least 600 grams in a low-traffic powder room and 800 grams or more in a daily-use bath, which the TOTO Aquia IV, Kohler Veil and TOTO Vespin II all meet or exceed.

Are Square and Modern Toilets Worth It?

Square and modern toilets are worth it when the look of your bathroom matters to you and you choose a model that backs the styling with a strong flush and serviceable parts. A skirted or one-piece modern toilet also wipes clean more easily because it hides the contoured trapway. The risk is buying a boutique model on looks alone and getting a weak flush, so prefer a major brand like TOTO or Kohler with a published MaP score of 800 grams or higher.

FAQ

Frequently Asked Questions

? What is a square toilet?

A square toilet has a squared-off, angular tank and often a squared bowl rim and base, replacing the rounded curves of a traditional toilet with crisp 90-degree lines. The look is usually paired with a skirted base that hides the contoured trapway behind a smooth panel, so the fixture reads as a single architectural shape. It is a design choice meant to suit a modern bathroom of straight lines and flat-panel surfaces.

? What is the best square or modern toilet?

The TOTO Aquia IV is the best square and modern toilet because its skirted, squared one-box body delivers a genuinely contemporary look while still posting a perfect 1,000-gram MaP flush, dual-flush efficiency and reliable TOTO parts support. The Swiss Madison St. Tropez is the value pick for a true geometric tank, while the Kohler Veil and Woodbridge T-0019 give the cleanest seamless one-piece cube look.

? Do square toilets flush as well as round ones?

They can, because flush power comes from bowl geometry, trapway size and the flush valve, not the shape of the tank or rim. The TOTO Vespin II and Kohler Memoirs Stately both post a maximum 1,000-gram MaP score in squared or skirted modern bodies. Some style-first boutique models do flush weakly, so check the published MaP score rather than assuming a sleek shape performs poorly.

? What is a skirted toilet?

A skirted toilet has a smooth side panel that wraps over the normally exposed, contoured trapway, so the base of the toilet reads as one clean flat shape rather than a lumpy traditional fixture. Skirted bodies are central to the modern look and are far easier to wipe down because there are no contours to clean around. The TOTO Aquia IV and Vespin II are popular skirted modern examples.

? Are square toilets harder to clean?

No, modern square and skirted toilets are usually easier to clean, not harder. The skirted base wipes down in a single pass with no exposed trapway contours, and one-piece bodies like the Kohler Veil have no tank-to-bowl seam to scrub. The main cleaning watch-point is the bowl interior, so choose a model with a fully glazed bowl, such as TOTO's CeFiONtect or Kohler's glazed surfaces, to resist streaking.

? Are square toilets less comfortable to sit on?

Comfort depends on the bowl shape and seat, not the tank. Most modern toilets pair a squared exterior with a standard elongated bowl opening, so the seating surface feels the same as a conventional elongated toilet. A few fully squared designs have a more angular seat, which some owners find less comfortable, so if comfort is a priority choose a modern model with a conventional elongated bowl and a comfort-height seat around 16.5 to 17 inches.

? Is a one-piece or two-piece modern toilet better?

One-piece modern toilets like the Kohler Veil and Woodbridge T-0019 give the cleanest seamless look and are easiest to clean, but they are heavier and cost more. Skirted two-piece toilets like the TOTO Aquia IV and Vespin II deliver most of the modern look for less money and weight, which is the sweet spot for many shoppers. Base the choice on flush power and rough-in first, then pick the body style and budget you prefer.

? Are modern toilets water efficient?

Most are, and you should confirm it on the spec sheet. Look for an EPA WaterSense label and a 1.28-gallons-per-flush rating or better, which uses about 20 percent less water than the 1.6-gallon federal maximum. The TOTO Aquia IV, Vespin II, Drake II and Kohler Veil all meet WaterSense efficiency, and several add a dual-flush button that pairs a 0.8-gallon liquid flush with a full flush for further savings.

? Do modern toilets use proprietary parts?

Some do, which is the main long-term risk in this category. Boutique brands and certain skirted or top-flush designs use proprietary fill valves, flush valves and dual-flush actuators that big-box stores do not stock. Favor a major brand like TOTO, Kohler or American Standard whose mechanisms a plumber can match, or order a spare valve up front, so a common repair never leaves the toilet out of service while you wait on a part.

? What brands make good square and modern toilets?

TOTO, Kohler and American Standard make the most reliable skirted and squared modern toilets with strong flushes and serviceable parts, with TOTO's Aquia IV and Vespin II and Kohler's Veil standing out. Swiss Madison and Woodbridge make stylish, lower-cost modern one-pieces like the St. Tropez, Sublime and T-0019, which look the part but use boutique parts, so weigh styling against long-term serviceability.

? Are wall-hung toilets a good modern option?

Wall-hung toilets like the Swiss Madison Sublime give the most minimalist, floating modern look and free the floor beneath the bowl for easy cleaning. The trade-off is installation: they require an in-wall steel carrier frame, sufficient wall depth and a concealed tank serviced through an access panel, which makes them a remodel-level project rather than a simple swap. They are an excellent choice when planned into a renovation.

? Do square toilets come in dual flush?

Yes, many do. The TOTO Aquia IV, Swiss Madison St. Tropez and Sublime, Kohler Veil and Woodbridge T-0019 are all dual flush, pairing a light flush for liquids with a full flush for solids. Dual flush is a natural fit for the water-conscious modern bathroom, and it lets a contemporary toilet save water without giving up the strong full flush needed for solids.

? What rough-in do modern toilets need?

Most modern toilets use the standard 12-inch rough-in, measured from the finished wall to the center of the floor bolts, the same as a conventional toilet. Skirted models can be slightly less forgiving of an off-spec rough-in because the panel must clear the floor flange, so measure carefully and check the spec sheet. Wall-hung models follow a different mounting standard set by their in-wall carrier frame.

? Do modern toilets come with a seat?

It varies, so check before you order. Many skirted two-piece toilets like the TOTO Aquia IV sell the matching seat separately, while several one-piece modern toilets such as the Woodbridge T-0019 include a soft-close seat in the box. Where the seat sells separately, buy the manufacturer's matching seat so the squared or contoured shape lines up correctly with the bowl.

? How do I keep a modern toilet from streaking?

Choose a model with a fully glazed, low-stick bowl surface such as TOTO's CeFiONtect or a comparable Kohler glaze, which resists the mineral and waste streaking that shows up faster on a high-design fixture. Clean with a non-abrasive cleaner to protect the glaze, and pick a model with an 800-gram or higher MaP score so the strong flush rinses the bowl thoroughly on every pull.

? Can a modern toilet handle a busy family bathroom?

Yes, if you choose one with a strong flush. The TOTO Vespin II and Kohler Memoirs Stately both post a 1,000-gram MaP score in modern bodies and are built for heavy daily use, and the Kohler Highline matches that flush power at a lower price. Avoid the weaker boutique models with 350 to 500 gram scores for a busy bathroom, since their lower flush power can lead to second flushes.

? Are square modern toilets more expensive?

Modern toilets do tend to cost more than basic round two-piece models, with skirted, one-piece and wall-hung designs at the top of the range. You can get the modern look for less by choosing a skirted two-piece like the TOTO Aquia IV or a clean-lined model like the Kohler Highline, or a value one-piece such as the Woodbridge T-0019 or Swiss Madison St. Tropez, rather than a premium seamless cube.

? What is the difference between a square and a skirted toilet?

A square toilet describes the angular, 90-degree styling of the tank and bowl, while a skirted toilet describes a base design where a smooth panel covers the trapway. The two often appear together in modern toilets, but they are different features: a toilet can be skirted without being fully squared, and a squared toilet can have an exposed trapway. Both contribute to the contemporary look and both are easier to clean than a rounded, exposed-trapway design.

? Does WaterSense certification matter for a modern toilet?

Yes. EPA WaterSense certification means the toilet uses 1.28 gallons per flush or less while still passing flush-performance standards, saving water and money over the life of the toilet. Because a modern bathroom is often a primary bath used many times a day, those per-flush savings add up across a year, so prefer a WaterSense-certified model such as the TOTO Aquia IV or Kohler Veil where your flush-power needs allow.

? Are modern toilets good for small bathrooms?

They can be, because skirted and one-piece modern bodies often have a low, compact silhouette that reads as more open in a tight room, and wall-hung models free the floor entirely. Look for a short-projection or compact-elongated model and a low tank profile. For a full set of small-space options across styles, see our dedicated guide to the best toilets for small bathrooms rather than choosing on looks alone.

Our Verdict

For most modern bathrooms, the TOTO Aquia IV is the best square and modern toilet, the skirted, squared one-box model that delivers the contemporary look people are shopping for while backing it with a perfect 1,000-gram MaP flush, dual-flush efficiency at 0.8 and 1.28 gallons, and real TOTO parts support. Choose the Swiss Madison St. Tropez for a true geometric tank on a budget, or the Kohler Veil when you want the cleanest seamless cube; the Woodbridge T-0019 gives that one-piece look for less with a seat included. If you would rather have a simpler single-flush valve at that same 1,000-gram score, step up to the TOTO Vespin II or the squared Kohler Memoirs Stately, and the Kohler Highline delivers modern lines and a strong flush for the least money. For a fully minimalist remodel, the wall-hung Swiss Madison Sublime is the most striking statement, while the TOTO Drake II is the clean-lined, reliable two-piece. Decide how much you value a seamless skirted base versus a dual-flush button, aim for an 800-gram or higher MaP score, and prefer a major brand whose flush valve any plumber can source, and any pick here will give you a modern bathroom that still flushes right for years.
