Steps to Replace Your Old Toilet

Would you like help checking the rough-in measurement (distance from the wall to the floor bolts) to make sure your chosen model fits your space?

Absolutely. For a replacement, I’d prioritize WaterSense certification, dual flush, an elongated bowl, and a skirted or one-piece design for the modern look. EPA says WaterSense toilets use 1.28 gallons per flush or less and are independently certified for both efficiency and performance.

Here are some good current options:

• DeerValley 1.28/1.0 GPF Dual-Flush - $228.00 (Lowe's)
• Eridanus Salerno Dual-Flush - $199.97 (Lowe's)
• TOTO Aquia Dual-Flush with Tornado Flush - $696.71 (Wayfair)
• American Standard Edgemere 1.28/1.0 GPF - $294.45 (Lowe's)
• DEERVALLEY Fully Skirted 1-Piece - $254.67 (The Home Depot)

My picks

• Best value/efficiency:

— one-piece, elongated, soft-close, and the 1.0/1.28 GPF combination is particularly attractive for water savings.

• Best modern design:

— sleek skirted profile and concealed trapway give it a very contemporary appearance.

• Best established-brand choice:

— chair height, elongated bowl, and a clean two-piece design.

• Budget option:

— around $200 and includes a soft-close seat.

One important detail: measure your existing toilet's rough-in before ordering. The most common measurement is 12 inches, but 10- and 14-inch configurations exist. Also check the toilet's overall depth so the new elongated bowl doesn't interfere with your bathroom door or cabinets.

If you tell me your budget (e.g. under $250, $500, or $1,000) and whether you prefer one-piece vs. two-piece, I can narrow this to the 3 best models for your bathroom.

Upgrading to a modern, high-efficiency dual-flush toilet is a great way to cut down on water usage (typically offering a choice between 1.1 GPF for liquid waste and 1.6 GPF for solid waste) while completely refreshing your bathroom's look.

To help you get started, here are key features to look for and top brands known for sleek, contemporary designs:

Key Design & Efficiency Features

1. Skirted Trapway: A smooth, fully skirted ceramic base hides the trapway discharge tubes, giving the toilet a seamless, architectural look that is much easier to wipe clean.
2. One-Piece vs. Two-Piece: One-piece modern toilets integrate the tank and bowl into a single, streamlined unit. They have fewer crevices, preventing dust and grime buildup.
3. Elongated Chair-Height Bowls: These offer extra ergonomic comfort (similar to standard chair heights), making sitting and standing significantly easier.
4. WaterSense Certification: Ensures the dual-flush mechanisms meet rigorous EPA criteria for efficiency without sacrificing flushing muscle.

Top Brand Recommendations

• TOTO: Renowned for advanced flushing dynamics like the DynaMax Tornado Flush Go to product viewer dialog for this item. and sleek minimalist profiles (such as the Aquia series).
• Kohler: Offers reliable performance with striking contemporary curves and efficient dual-flush capabilities.
• DeerValley / WoodBridge: Great budget-to-mid-tier options featuring fully skirted, modern one-piece designs with soft-close seats widely available online.

To narrow down the best specific model for your space, could you tell me:

• What is your rough-in measurement (the distance from the wall to the floor bolts—standard is 12 inches)?
• Do you prefer a one-piece or two-piece design?
• Are you looking for a floor-mounted or a space-saving wall-mounted option?

Absolutely. For a modern replacement, I’d focus on a one-piece, elongated, dual-flush toilet with a skirted bowl. It gives you the clean contemporary look while making the exterior easier to clean.

EPA WaterSense is a particularly useful benchmark: certified toilets use 1.28 gallons per flush or less and are independently tested for performance. Dual-flush models let you use a smaller flush for liquid waste.

• WOODBRIDGE Everette 1-Piece Dual Flush - $316.85 (The Home Depot)
• Swiss Madison Sublime 1-Piece Dual Flush - $254.90 (The Home Depot)
• HOROW 17-in ADA Dual Flush - $289.00 (The Home Depot)
• DEERVALLEY 1-Piece ADA Dual Flush - $265.00 (The Home Depot)
• Glacier Bay 2-Piece Dual Flush - $99.00 (The Home Depot)

My top choices

• Best overall modern look:

— sleek one-piece construction, elongated bowl, 1.28 GPF full flush, and a contemporary appearance.

• Best value for a very modern bathroom:

— 0.8/1.28 GPF and a fully skirted, seamless look.

• Best if comfort height matters:

— taller seating and a modern one-piece design.

• Best budget option:

— substantially cheaper while offering 1.0/1.28 GPF and WaterSense certification.

Before buying, check your existing toilet's rough-in measurement (usually 12 inches), whether you want standard or comfort/ADA height, and the available space in front of and behind the toilet. Also verify the specific toilet/tank-and-bowl combination is WaterSense-certified; EPA notes that not every combination of separately sold components qualifies.

If you tell me your budget (e.g. under $300, $500, or $1,000) and whether you prefer one-piece or two-piece, I can narrow this to the best 3 models for your bathroom.

Upgrading to a modern, high-efficiency dual-flush toilet is a great way to cut down on water usage while giving your bathroom a sleek aesthetic update. Modern units typically feature fully skirted trapways, slim profile cisterns, and top-mounted dual-flush buttons.

Top Modern Dual-Flush Toilet Options

Swiss Madison St. Tropez One-Piece Dual-Flush Toilet – A popular one-piece model featuring a fully skirted, concealed trapway, a sleek vortex flush, and a soft-close seat (available in gloss white as well as bold contemporary finishes like matte black).

TOTO Aquia IV Two-Piece Elongated Toilet – Renowned for its minimalist design, high-efficiency dual flush (0.8 / 1.28 GPF), superior Tornado Flush technology, and CEFIONTECT ceramic glaze that prevents waste from sticking.

WOODBRIDGE One-Piece Dual-Flush Smart/Standard Toilet – Combines a seamless, modern skirted trapway design with high-end features like comfortable chair heights and ultra-efficient dual-flush options.

What to Measure Before Buying

1. Rough-In Distance : Measure the distance from the finished wall (not the baseboard) to the center of the floor bolts holding your current toilet down. Standard is 12 inches, but older or compact spaces can sometimes be 10 inches or 14 inches.
2. Bowl Height : Decide between standard height (~ 15 inches) or ADA-compliant comfort/chair height (17–19 inches), which is much easier on the knees and hips.
3. Trapway Style : Look for a skirted trapway , meaning the sides of the toilet base are completely smooth rather than undulating around the drain bend. This eliminates those hard-to-clean crevices on the exterior.

To help narrow down the ideal model for your space, could you let me know:

• What is your rough-in measurement (10, 12, or 14 inches)?
• Do you prefer a one-piece or two-piece design?

Absolutely. For a modern, efficient dual-flush toilet, I’d focus on a one-piece elongated design with a skirted trapway and a low-flow setting around 0.8–1.1 GPF. EPA WaterSense toilets use 1.28 GPF or less and can substantially reduce toilet water use compared with older models.

What I'd buy

For a typical bathroom, I'd choose the DEERVALLEY 1.0/1.28 GPF if keeping the price around $300, or the TOTO Aquia IV if you're willing to spend more for a premium model.

One important thing before ordering: measure the rough-in—the distance from the finished wall behind the toilet to the center of the floor drain/closet bolts. 12 inches is common, but 10- or 14-inch rough-ins exist, and the toilet needs to match.

Also check whether your existing toilet is standard or chair height, and whether you want elongated or round. Home Depot's current modern dual-flush WaterSense selection includes both one- and two-piece models in different rough-ins and heights.

If you tell me your budget (e.g. under $300, $500, or $1,000) and whether you have a 12-inch rough-in, I can narrow this to the 3 best models for your bathroom.

Upgrading to a modern, dual-flush toilet is an excellent way to elevate your bathroom's design while lowering your water bill . The most critical factor in choosing a modern toilet is opting for a one-piece, fully skirted design . Skirted trapways eliminate the traditional, hard-to-clean curves behind the bowl, replacing them with smooth, sleek exterior surfaces that look highly contemporary and prevent grime buildup.

Here are top specific choices depending on your budget and style preference:

• Features a completely seamless, skirted trapway that provides a stunning, high-end minimalist appearance.

• Utilizes a highly efficient dual-flush setup (typically 1.1/1.6 GPF or a specialized 1.28 GPF system).

• Includes a top-tier soft-closing seat with durable stainless steel hinges for silent use.

• Offers an ultra-modern, European-inspired square-off profile that pairs beautifully with minimalist decors.

• Uses a powerful Dual Vortex flush technology that maintains maximum cleanliness while using only 1.1 or 1.6 gallons per flush.

• Features premium custom finish options for the top flush button, like brushed gold or matte black, to match your vanity hardware.

• Perfect if you want an ultra-efficient model, offering an impressive ultra-low 0.8 GPF option for liquid waste and 1.28 GPF for solids.

• Features a slightly more compact elongated footprint, making it ideal for freeing up space in smaller modern bathrooms.

• Highly rated for powerful, quiet siphonic jet flushing action that minimizes repeated flushes.

Critical Specifications to Check Before You Buy

To avoid returning a heavy item, make sure you verify these three standard metrics in your bathroom:

1. Rough-In Measurement : This is the distance from the finished wall behind the toilet to the center of the floor bolts holding the toilet down. The standard size is 12 inches , but older homes sometimes require a 10-inch or 14-inch rough-in.
2. Bowl Height : Decide if you prefer standard height (approx. 15 inches, ideal for households with children) or "Comfort/Chair Height" (17+ inches, which is much easier on the knees for adults).
3. WaterSense Certification : Check for this label to ensure the toilet meets strict EPA criteria for efficiency, which can save you up to 4,000 gallons of water annually and may qualify you for local utility rebates.

To help you choose the perfect fit, what is the rough-in measurement of your current toilet? Sharing your budget or if you need an ADA-compliant chair height model would also help.

Absolutely. For a modern-looking, efficient dual-flush toilet, I’d focus on a one-piece, elongated, skirted model. The skirted exterior gives you the clean contemporary look and is easier to wipe down.

EPA WaterSense is a good benchmark: certified toilets use 1.28 gallons per flush or less on the full flush while meeting performance requirements.

2. Check the height : Decide whether you want standard height (~15 inches) or ADA-compliant chair-height/comfort height (~17 to 19 inches) for easier sitting and standing.
