I want a toilet with straight lines and a very clean look. Any recommendations?

For a truly clean, architectural look with straight lines and sharp geometric profiles, you'll want to look at skirted trapway toilets (which hide the messy curves of the plumbing) or wall-hung options for a seamless floating effect.

Top recommendations matching a sleek, linear, and minimalist aesthetic:

Add to list

• Design Style: A striking geometric, one-piece build featuring a squared-off bowl and crisp, flat sides.
• Clean Factor: Fully skirted trapway means zero exposed side nooks or crannies, making clean-up fast and straightforward.
• Details: Includes a soft-close, quick-release matching square seat. Available to view or order via platforms like SuperArbor.

Add to list

• Design Style: The ultimate expression of modern minimalism. Because the tank is hidden inside the wall, you only see a sharp, geometric square bowl suspended off the floor.
• Clean Factor: Floating design allows you to easily mop underneath the toilet entirely, and TOTO's CeFiONtect ceramic glaze prevents debris from sticking to the surface.
• Details: Pairs with an in-wall tank system (like the TOTO DuoFit) and requires their dedicated square slim soft-close seat. Check specifications and sourcing via suppliers like SupplyStop.

Add to list

• Design Style: Features blocky, linear contours that transition smoothly from tank to base without awkward curves.
• Clean Factor: A fully concealed, skirted trapway streamlines the exterior profile so it wipes down in seconds.
• Details: Integrated quiet dual-flush system. You can explore listing details on Wayfair.

To help narrow this down, let me know:

• Do you prefer a standard floor-mounted toilet or are you open to a wall-hung model (which requires in-wall tank installation)?
• What is your preferred rough-in size (usually 12 inches)?

Absolutely. If by straight lines + very clean look you mean something architectural rather than the traditional rounded toilet, I’d focus on one-piece, fully skirted toilets—the smooth sides hide the trapway and make the whole toilet much easier to wipe clean.

My top picks

• Duravit D-Neo One-Piece - $494.10 (The Home Depot)

• Swiss Madison Carré One-Piece - $465.86 (The Home Depot)

• KOHLER Veil One-Piece - $1,158.99 (Wayfair)

• TOTO Aquia IV - $597.99 (Lowe's)

• Duravit D-Neo — my favorite for your description. It has particularly crisp geometric proportions and straight lines rather than a rounded, decorative look. The D-Neo collection explicitly emphasizes straight lines and geometric shapes.

• Swiss Madison Carré — probably the most square/modern-looking for the money. Fully skirted, one-piece, and available around the $300–$465 range depending on version/seller.

• Kohler Veil — a beautiful, minimalist option with a seamless skirted exterior. It's more architectural and slightly curved than truly rectilinear. KOHLER describes it as a bold minimalist design.

• TOTO Aquia IV — less aggressively square, but an excellent combination of clean appearance, easy cleaning and flushing performance. It has a fully skirted body and dual flush.

If you want really straight lines

I'd actually look at a wall-hung toilet. With the tank concealed in the wall and the bowl floating above the floor, you get the cleanest possible bathroom geometry.

The TOTO SP square wall-hung and Swiss Madison Carré wall-hung are particularly aligned with that aesthetic.

If you show me a photo of the bathroom or tell me your budget (e.g. <$500, $500–$1,000, $1,000+), I can narrow it down to 3 toilets that match the exact look.

Absolutely. For straight lines + a very clean, architectural look, I’d focus on a one-piece, skirted toilet. The skirt hides the trapway and eliminates the usual nooks and bolt caps, so the exterior reads as one smooth shape.

My top picks

• TOTO Nexus One-Piece - $1,109.35 (The Home Depot)

• Duravit D-Neo One-Piece - $494.10 (The Home Depot)

• KOHLER Veil One-Piece - $1,158.99 (Wayfair)

• DEERVALLEY Fully Skirted One-Piece - $254.67 (The Home Depot)

• TOTO Nexus — my pick if you want the cleanest straight-sided look. It has a high-profile, skirted silhouette and a 1.28 GPF single flush, so you avoid the visual clutter of a dual-flush button.

• Duravit D-Neo — probably the most design-forward option. Duravit specifically describes the D-Neo collection around straight lines and geometric forms.

• KOHLER Veil — extremely minimalist and seamless, although its shape is a little more sculpted/curved than what you're describing. It has a skirted trapway and one-piece construction.

• DEERVALLEY fully skirted — a much more affordable option if you want the general aesthetic without spending $1,000+.

If “straight lines” is the priority

I'd rank them:

1. TOTO Nexus → 2. Duravit D-Neo → 3. KOHLER Veil

I'd skip very rounded “modern” toilets—some are marketed as minimalist but have pronounced curves that make them look more sculptural than architectural.

If you tell me your budget (e.g. under $500 / $1,000 / $1,500) and whether you want standard or comfort height, I can narrow it down to 3 specific models.

If you want a toilet with straight lines, sharp geometric balance, and an ultra-clean aesthetic, you'll want to look for square/angular bowls and fully skirted trapways (which hide the messy curves of standard plumbing and make cleaning a breeze).

Top recommendations matching that sleek, architectural look include:

A fantastic geometric option featuring crisp, sharp edges, a squared-off bowl design, and a fully skirted, concealed trapway. It offers a true modern/contemporary profile and is available on platforms like The Home Depot.

If you want an extreme architectural statement with ultra-clean lines, this minimalist model pairs with a concealed in-wall cistern to completely hide the tank and pipework, leaving just a sharp, geometric profile against the wall. You can check it out directly via Lusso Stone.

Features a pronounced contemporary square front, a streamlined one-piece body, and a concealed trapway that stops dust and dirt from building up in side curves. It's a great mid-range choice often found at retailers like Lowe's.

While it has a slightly softer elongated oval shape rather than a hard square, TOTO’s skirted design provides an impeccably smooth, uninterrupted, and sophisticated silhouette that maximizes a clean, modern look while offering legendary flushing performance.

Would you prefer a floor-mounted one-piece toilet, or are you open to a wall-hung toilet with a concealed tank for the absolute cleanest look?

Absolutely. If by straight lines + very clean look you mean something more architectural and minimal—not the rounded, traditional toilet shape—I’d focus on skirted one-piece toilets.

My top picks

• TOTO Aquia IV - $284.99 (Wayfair)

• KOHLER Veil - $1,140.45 (Wayfair)

• DEERVALLEY Fully Skirted - $254.67 (The Home Depot)

• Swiss Madison Voltaire - $386.30 (The Home Depot)

• TOTO Aquia IV — my overall pick. Very clean, contemporary proportions, fully skirted sides, and TOTO's DynaMax Tornado Flush. The one-piece version is particularly seamless.

• KOHLER Veil — best high-end minimalist look. It's extremely clean and sculptural, with a skirted trapway and one-piece construction. KOHLER specifically describes the design as minimalist and easy to clean.

• Swiss Madison Voltaire — good mid-priced option if you want a more angular, straightforward silhouette. It has a full skirt and a single flush handle rather than a dual-flush button.

• DEERVALLEY fully skirted — budget choice. Surprisingly clean-looking for the price, with a one-piece fully skirted body.

If you want really straight lines

I'd lean toward the TOTO Aquia IV over the Veil. The Veil is beautiful but has more sculpted/curved transitions; the Aquia reads more crisp, restrained, and architectural.

If you're going for a bathroom that looks like a high-end modern hotel/spa, I'd also consider a wall-hung toilet. The KOHLER Veil wall-hung model is particularly clean because the tank is concealed in the wall and the floor underneath stays completely open.

If you tell me your budget (e.g. under $500, $1,000, $1,500+) and whether you want floor-mounted or wall-hung, I can narrow it down to 3–5 toilets that really match that straight-line aesthetic.

If you want a toilet with straight lines, sharp geometric balance, and an ultra-clean appearance, you'll want to look at fully skirted trapway designs (which hide the messy curves of standard plumbing) or square-bowl modern profiles.

Top recommendations matching a minimalist, straight-lined aesthetic include:

A striking geometric option featuring a true square bowl and crisp, sharp lines. It uses a fully skirted, concealed trapway that eliminates dust-collecting crevices and creates a completely seamless silhouette.

Known for a heavy architectural look with flat, clean sides and a low-profile tank. It features a skirted base with zero hard-to-reach grooves and comes with sleek top-mounted dual-flush buttons (available in finishes like brushed nickel or matte black).

If you prefer a slightly more tailored look rather than an aggressive modern box shape, this model blends traditional architectural lines with a smooth, concealed skirted lower base that is exceptionally easy to wipe down.

While TOTO leans into smooth curves on some models, the Aquia line offers a finely balanced, highly upright, minimalist profile with a completely smooth skirted side that embodies understated, clean modernism.

To help narrow down the exact right fit, do you prefer a sharp square bowl or a smooth contemporary rounded-rectangle , and do you need a one-piece or two-piece setup?

Absolutely. If by “straight lines and very clean” you mean something architectural rather than the traditional rounded toilet, I’d look for a one-piece, skirted toilet with a squared-off tank and concealed trapway.

My top picks

TOTO Aquia IV

$1,025.26

American Standard Studio S

$562.90

Swiss Madison Carré

$369.09

WOODBRIDGE Modern

$375.83

1. TOTO Aquia IV — best overall
Very clean, contemporary silhouette without looking overly futuristic. The skirted base hides all the plumbing contours, and TOTO's Dynamax Tornado Flush gives it a more premium feel. The current listing I found is around $1,025, so it's definitely the splurge option.

2. American Standard Studio S — best balance of design + price
This is probably the one I'd choose for your description. It has very straight, smooth sides and a concealed trapway, while still looking like a conventional floor-mounted toilet. American Standard specifically describes it as a minimalist design, and current pricing is roughly $510–$560.

3. Swiss Madison Carré — most geometric
If you really mean square/rectilinear, this is the look. The Carré has a square bowl and fully skirted body, with a particularly clean modern profile. It's around $300–$370 in the current listings.

4. WOODBRIDGE Modern — dramatic modern look
More architectural and substantial-looking, with a square-ish tank and completely concealed trapway. Around $375 currently.

One more if you want really high-end

KOHLER Veil Intelligent Toilet

$5,999.96

The KOHLER Veil is the most architectural of the bunch. The standard Veil is a minimalist, skirted one-piece; the intelligent version takes that look much further with the bidet functionality integrated into the toilet. KOHLER describes the standard model as a bold minimalist design with an easy-clean skirted trapway.

For your particular aesthetic, I'd rank them:
Studio S → TOTO Aquia IV → Swiss Madison Carré → KOHLER Veil

If you tell me your budget (e.g. under $500 / $1,000+) and whether you want a round or elongated bowl, I can narrow it down to 3 that look exactly like what you're picturing.

For a truly clean, architectural look with straight lines, you’ll want to look at fully skirted (concealed trapway) models or geometric/square-bowled designs . Skirted toilets eliminate those awkward, dust-collecting curves and exposed trapway tubes on the sides, giving you a smooth, flat vertical wall from the tank down to the floor.

Top recommendations that match a sleek, linear, and minimalist aesthetic include:

Add to list If you want literal straight lines and sharp angles, this one-piece features a distinct square bowl and structured geometric tank . It has a fully skirted, smooth-sided trapway and comes in glossy white or a striking matte black.

Add to list If "straight lines" means a seamless, vertical drop without the chunky look of a traditional toilet, the St. Tropez is a favorite . It’s a one-piece with a completely smooth, concealed trapway and a dual vortex flush that hugs the wall cleanly.

Add to list Perfect if you lean toward transitional or soft-modern architecture. It mimics classic wainscoting and squared lines on the upper tank/base interface while keeping the lower bowl entirely skirted and free of hidden crevices.

Add to list An exceptional budget-to-mid-range pick that gives you an ultra-streamlined silhouette . It features sharp, minimalist sides and a dual-flush push button centered cleanly on top of the tank.

Add to list A higher-end option known for true rectangular precision. It delivers a deeply modern, boxy profile that looks like a built-in architectural block rather than a traditional porcelain fixture.

To help narrow down the ideal match , tell me:

• Do you prefer a soft geometric square shape or a smooth rounded oval with a flat skirt?
• Are you working with a standard 12-inch rough-in , or do you need a specific size?

For a modern bathroom with crisp, straight lines and an uninterrupted clean look, you'll want to look at fully skirted (concealed trapway) and geometric/square-profile one-piece toilets. Skirted models eliminate the dusty, winding curves of traditional side trapways, giving you a flat, slab-sided surface that is both minimalist and easy to wipe down.

Top recommendations matching this aesthetic include:

Features sharp geometric balance and a true square bowl design with straight, clean vertical lines down to the floor. It comes fully skirted, has a dual-flush push button option, and offers an ultra-contemporary look without a massive price tag.

Known for its remarkably fluid yet starkly minimalist profile. It almost reads as a hybrid between a tankless and standard one-piece unit, making it a favorite for high-end modern spaces.

Offers a sharp, back-to-the-wall contemporary design with a smooth skirted base and a top-mounted dual-flush button. It provides a seamless visual block that blends seamlessly into modern minimalist tiles or baseboards.

If you prefer a slightly softer, transitional line that still maintains a completely concealed skirted trapway and a flat-sided profile, TOTO's modern lineup (often paired with their CEFIONTECT glaze) keeps the exterior sleek and extraordinarily clean.

User Experiences

“The toilet looks great in my bathroom. The tall height is perfect for eliminating pain from getting up. Easy to clean on the outside.”

To help narrow down the best fit, tell me:

• Are you looking for a true square-shaped bowl or a standard elongated oval with a flat skirted side?
• Do you prefer a top push-button dual flush or a traditional side trip-lever?

Absolutely. If by “straight lines and very clean” you mean more architectural/geometric than rounded and traditional, I’d focus on square-front, one-piece, skirted toilets. A skirted trapway hides the plumbing contours and gives you that uninterrupted side profile.

My top picks

Duravit DuraStyle One-Piece Square Toilet

$682.09

Swiss Madison Carré One-Piece Square Toilet

$369.09

KOHLER Gleam Skirted Toilet

$279.00

TOTO Square Wall-Mounted Toilet

$1,630.92

1. Duravit DuraStyle — best for a high-end minimalist look
This is probably closest to what you're describing. Duravit explicitly designed the D-Neo/DuraStyle aesthetic around straight lines and geometric shapes. The DuraStyle one-piece has a very restrained, almost architectural appearance.

2. Swiss Madison Carré — best value for the look
The Carré is genuinely square and geometric rather than merely a conventional toilet with a slightly modernized shape. It's one-piece and fully skirted, so you get a very clean silhouette without spending Duravit money.

3. KOHLER Veil — best premium option
KOHLER Veil toilets are exceptionally clean-looking, particularly the one-piece version. It's skirted, seamless and available in wall-hung versions. The caveat: Veil is more softly sculpted than truly square, so I'd choose it if you want minimalist luxury rather than strict straight lines.

4. TOTO square wall-hung — most architectural
If you're doing a renovation and can accommodate an in-wall carrier/tank, a wall-hung square toilet gives you the cleanest possible bathroom composition. It eliminates the visible pedestal and makes the floor much easier to clean.

If it were my bathroom

I'd narrow it to:

• Most beautiful / designer: Duravit DuraStyle
• Best-looking without going crazy on price: Swiss Madison Carré
• Most luxurious/minimal: KOHLER Veil wall-hung
• Most “architect-designed”: TOTO square wall-hung

One important thing: don't search only for “modern toilet.” You'll get lots of toilets with rounded, bulbous profiles. Search for “square-front + one-piece + skirted” or “wall-hung + square.”

If you tell me your budget (e.g. under $500, $500–$1,000, $1,000+) and whether you want floor-mounted or wall-hung, I can narrow it down to 3–5 really good choices.
