I want to replace my old toilet with a more efficient, dual-flush model that has a modern design.

Absolutely. For a replacement, I’d look for a one-piece, elongated, dual-flush toilet with a skirted bowl and a WaterSense label. EPA says WaterSense-labeled toilets use 1.28 gallons per flush or less and are independently certified for both efficiency and flushing performance.US EPA+1

Current options worth considering

• American Standard H2Option 0.92/1.28 GPF - $419.09 (The Home Depot)

• WOODBRIDGE Everette 1.28 GPF - $304.20 (The Home Depot)

• HOROW Matte White 1.1/1.6 GPF - $251.30 (The Home Depot)

• Swiss Madison Beau 1.1/1.6 GPF - $269.99 (The Home Depot)

• DeerValley Ace 1.28/1.0 GPF - $287.90 (Lowe's)

• American Standard H2Option — 0.92/1.28 GPF dual flush, elongated chair-height design. A particularly water-efficient conventional option.

• WOODBRIDGE Everette — 1.28 GPF dual flush, one-piece skirted design with a contemporary appearance.

• HOROW Matte White — 1.1/1.6 GPF, one-piece ADA/chair-height design with a distinctive matte-white finish.

• Swiss Madison Beau — 1.1/1.6 GPF, sleek one-piece styling and soft-close seat.

• DeerValley Ace — 1.0/1.28 GPF, one-piece chair-height design and soft-close seat.

One important detail: don't judge efficiency just by the "dual flush" label. WaterSense certification uses the toilet's tested effective flush volume, and EPA's current consumer guidance recommends looking for the WaterSense label rather than simply choosing a low advertised number.US EPA+1

Before ordering, measure your existing toilet's rough-in (usually 12 inches), check whether you want standard or chair height, and verify whether the seat is included. If you give me your budget (e.g. under $300/$500), preferred height, and whether you want white or a modern color, I can narrow these down to a few suitable models.

You can find modern, efficient dual-flush models like the Swiss Madison St. Tropez 1-Piece Toilet or the Kohler Wellworth Dual-Flush Toilet to upgrade your bathroom.[1]

Key Steps to Replace Your Toilet

1. Measure the rough-in size : Measure the distance from the wall (not the baseboard) to the floor bolts holding your current toilet. Standard size is 12 inches.
2. Turn off the water supply : Locate the shut-off valve behind the toilet, turn it clockwise, and flush the toilet to empty the tank.
3. Disconnect the supply line : Use a wrench to detach the water supply hose from the bottom of the tank.
4. Remove the old toilet : Uncap and remove the floor bolt nuts, pry off decorative caps if present, and carefully lift the old unit straight up off the wax ring.
5. Clean the flange and insert a new wax ring : Stuff a rag in the open drain pipe to block sewer gases while you scrape away the old wax seal. Remove the rag, then press a new wax ring onto the floor flange.
6. Set the new toilet : Align the base holes with the floor bolts and lower the toilet straight down. Press firmly to seal the wax ring.
7. Secure and reconnect : Tighten the bolt nuts evenly (do not over-tighten or you might crack the ceramic base), attach the water supply line, and turn the water back on.

Popular Dual-Flush Options

Model	Type	Average Price	Key Feature
Swiss Madison St. Tropez	One-Piece	$255	Sleek skirted trapway
HOROW Dual Flush R01D	Two-Piece	$229	Chair-height comfort

If you want to narrow down your choice, tell me:

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

Upgrading to a modern, dual-flush toilet is a great way to cut down on water usage while giving your bathroom a clean, contemporary aesthetic. Skirted trapways and one-piece designs are especially popular for that sleek look and easier cleaning.

Here are a few well-reviewed, modern dual-flush options ranging from streamlined one-piece toilets to high-tech smart models:

Swiss Madison Ivy One-Piece Toilet ($281 on Home Depot / Wayfair ): Combines a seamless modern silhouette with a dual vortex flush and chic hardware finish options (like brushed gold) to elevate your bathroom's look.

WOODBRIDGE Smart Bidet Toilet ($1,199 on Home Depot ): If you want ultra-modern luxury, this integrates a high-efficiency dual flush (1.0 / 1.6 GPF) with auto open/close, a foot sensor, and a heated seat.

DeerValley Wall-Hung Concealed Tank Toilet ($399 on Wayfair ): Perfect for a minimalist or ultra-contemporary bathroom remodel, saving floor space with an in-wall concealed tank.[1][2][3][4]

To help narrow down the best fit, could you tell me:

• What is your rough-in measurement (the distance from the wall to the floor bolts, usually 12 inches)?
• Are you looking for a standard floor-mounted toilet or a wall-hung/smart unit?

Absolutely. For a modern replacement, I’d focus on a one-piece, elongated, dual-flush toilet with a skirted exterior and WaterSense certification. EPA says WaterSense-labeled toilets use 1.28 gallons per flush or less and are independently tested for performance.US EPA

What I'd check before ordering

The biggest issue isn't the appearance—it's fit. Measure:

• Rough-in: distance from the finished wall to the center of the floor bolts, usually 12", but 10" and 14" are also common.
• Bowl shape: elongated generally gives a more modern look and more sitting room.
• Height: chair/comfort height is typically easier to sit down and stand up from.
• Seat: check whether it's included; some otherwise identical models don't include one.
• Water efficiency: look for the WaterSense label, rather than relying solely on a manufacturer's "high efficiency" claim.US EPA

One wrinkle: EPA's current WaterSense page says its newer Version 2.0 specification is currently paused, with Version 1.2 remaining in effect until further notice. So I'd verify the specific model's current WaterSense certification before buying.US EPA

If you tell me your budget (e.g. under $300, $500, or $1,000) and whether your current toilet has a 10", 12", or 14" rough-in, I can narrow these down to the most suitable models.

Absolutely. For a modern replacement, I’d prioritize dual-flush + WaterSense certification + an elongated, skirted one-piece design. EPA says WaterSense toilets use 1.28 gallons per flush or less while meeting performance requirements, and dual-flush models let you use a smaller flush for liquid waste.US EPA+1

One important check before ordering: measure your existing toilet's rough-in—the distance from the finished wall behind the toilet to the center of the floor drain, typically 10, 12, or 14 inches. Also check whether you want standard or comfort/ADA height.

If you tell me your budget (e.g. under $300, $500, or $1,000), rough-in size, and whether you prefer white or another finish, I can narrow this to the 3 best choices for your bathroom.
