Purchasing a toilet is a decision that blends practicality with personal preference, impacting your daily comfort, bathroom aesthetics, and even your utility bills. With countless models on the market—ranging from basic budget options to high-tech luxury fixtures—finding the perfect fit can feel overwhelming. This detailed step-by-step guide breaks down the process into manageable steps, exploring critical factors like size, style, flush technology, and more to ensure you choose a toilet that seamlessly suits your bathroom and lifestyle.
Step 1: Measure Your Space with Precision
The foundation of any toilet purchase is ensuring it fits your bathroom physically. A mismatch in measurements can lead to installation headaches or an impractical layout, so start here.
-
Rough-In Distance: This is the measurement from the wall behind the toilet to the center of the drainpipe or floor bolts. The industry standard is 12 inches, fitting most modern homes. However, older homes might have 10-inch or 14-inch rough-ins. To measure, locate the bolts at the base of your current toilet (remove the caps if needed) and measure to the finished wall (not the baseboard). A wrong rough-in means either returning the toilet or modifying your plumbing—a costly fix.
-
Width and Depth: Toilets vary in footprint. A typical two-piece model might be 28–31 inches deep (front to back) and 18–21 inches wide, while compact or one-piece designs can shave off a few inches. Measure your available space, accounting for nearby fixtures like vanities or tubs. Building codes often require 15 inches of clearance from the toilet’s centerline to any obstruction and 24 inches in front for legroom.
-
Height Clearance: Check the vertical space above the toilet. Tanks on two-piece models can reach 30–32 inches high, while one-piece toilets are often shorter (26–29 inches). Ensure there’s no overlap with windowsills, shelves, or cabinets that could block tank access or lid movement.
Pro Tip: Use a tape measure and notepad to sketch your bathroom layout, marking doors, vents, and other obstacles. This visual aid helps when comparing toilet dimensions online or in-store.
Step 2: Decide Between One-Piece and Two-Piece Toilets
The structural design of a toilet affects its look, maintenance, and installation process. Here’s a closer look at your options.
-
One-Piece Toilets: These feature a seamless tank-to-bowl design, offering a sleek, modern appearance with fewer crevices for dirt to hide. They’re easier to clean but tend to be heavier (80–120 lbs) and pricier (starting at $200–$300). Installation can be trickier due to the weight, and repairs might require replacing the entire unit if the bowl or tank fails. Example: Kohler Santa Rosa.
-
Two-Piece Toilets: With a separate tank and bowl bolted together, these are more traditional and budget-friendly (often $100–$250). They’re lighter to handle (tank and bowl can be installed separately), and if one part breaks, you can replace just that component. However, the seam between tank and bowl can collect grime. Example: Kohler Highline Classic.
Consideration: If you value a minimalist look and have help for installation, a one-piece is ideal. For cost savings and DIY ease, a two-piece is a practical choice.
Step 3: Choose the Right Bowl Shape
The bowl’s shape influences both comfort and how much space the toilet occupies.
-
Round Bowls: Measuring about 16–17 inches from front to back, round bowls are compact and perfect for small bathrooms, powder rooms, or homes with young kids (easier for little ones to use). They’re less comfortable for adults due to the smaller seating area and can feel cramped over time.
-
Elongated Bowls: Extending 18–19 inches, these provide more room and better ergonomics, making them the go-to for most modern bathrooms. They’re especially comfortable for larger individuals but require more floor space, which could crowd a tight layout.
Detailed Insight: In a bathroom under 30 square feet, a round bowl saves precious inches. For master suites or family bathrooms, elongated bowls enhance comfort and are worth the extra space. Test both shapes in a showroom if possible to feel the difference.
Step 4: Select the Ideal Height
Toilet height—measured from floor to rim (excluding the seat)—affects ease of use and accessibility.
-
Standard Height (14–15 inches): Common in older homes, this height suits shorter users or children but can strain knees when standing up, especially for taller adults or seniors.
-
Comfort Height (17–19 inches): Also called “chair height,” this matches a typical dining chair and meets ADA accessibility standards. It’s easier on joints, making it ideal for aging-in-place homes, tall individuals, or anyone with mobility challenges.
Extra Detail: Comfort Height toilets often feel more luxurious and are increasingly standard in new builds. Add a seat (typically 1–2 inches thick) to the rim height for the final sitting level—test it to ensure it feels natural. Brands like Kohler (Highline) and Toto (Drake) excel in this category.
Step 5: Evaluate Flush Systems
The flush mechanism determines how well the toilet clears waste, how much water it uses, and how loud it is.
-
Gravity Flush: Water flows from the tank to the bowl using gravity—simple, quiet, and low-maintenance. Most use 1.28–1.6 GPF. They’re reliable for light use but may need multiple flushes for heavy waste.
-
Pressure-Assisted Flush: Compressed air boosts the flush (e.g., Kohler Pressure Lite, 1.6 GPF), sending waste further down the drain. It’s clog-resistant and powerful but louder and pricier, with more complex internals.
-
Dual Flush: Two buttons or levers offer a low flush (0.8–1.0 GPF) for liquids and a full flush (1.6 GPF) for solids. It’s eco-friendly and versatile but can confuse users, and repairs may cost more.
In-Depth Tip: For busy households, pressure-assisted or dual-flush systems shine. In quiet settings (e.g., near bedrooms), gravity flush keeps noise down. Check MaP scores (Maximum Performance testing) online—scores above 800 grams indicate top flushing power.
Step 6: Prioritize Water Efficiency
Water usage impacts both sustainability and your budget.
-
1.6 GPF: The former standard, still effective but less efficient than modern options.
-
1.28 GPF: WaterSense-certified toilets use 20% less water than 1.6 GPF models, saving up to 16,500 gallons yearly per household. They balance power and conservation well.
-
1.0 GPF or Less: Ultra-low-flow options cater to eco-conscious buyers, though weaker flushes may require double flushing, negating some savings.
Extra Insight: Look for WaterSense labels and local utility rebates (sometimes $50–$100). High-efficiency models like Toto Eco Drake (1.28 GPF) prove you don’t need lots of water for performance.
Step 7: Align Style with Your Bathroom
A toilet isn’t just functional—it’s part of your décor.
-
Traditional: Curved edges, ornate bases, and white finishes suit vintage or cozy spaces. Think American Standard Town Square.
-
Contemporary: Clean lines, flat tanks, and one-piece designs fit modern or minimalist bathrooms. Example: Kohler Veil.
-
Colors and Finishes: White dominates, but biscuit, black, or gray can make a statement. Matte or glossy finishes add flair but may limit fixture pairing options.
Detail: Match the trip lever (chrome, bronze) to your faucets. A bold color works in a guest bath; stick to neutral in shared spaces for resale value.
Step 8: Explore Extra Features
Modern toilets offer upgrades for convenience and hygiene.
-
Soft-Close Seats: Hinges prevent slamming—great for kids or late-night use.
-
Self-Cleaning: Systems like Kohler ContinuousClean use tablets to keep bowls fresh.
-
Bidet Functionality: Add-on seats or built-in sprayers elevate cleanliness.
-
Smart Features: Heated seats, nightlights, or auto-flushing appear in luxury models (e.g., Toto Washlet).
Consideration: Features add $50–$500 to the price. Prioritize based on need—bidets are trending for health-focused buyers.
Step 9: Set a Realistic Budget
Toilets span a wide price range.
-
Budget ($100–$300): Basic gravity-flush, two-piece models (e.g., Glacier Bay).
-
Mid-Range ($300–$600): Enhanced features like Comfort Height or dual flush (e.g., Kohler Cimarron).
-
Luxury ($600–$2,000+): Designer looks, smart tech, or premium materials (e.g., Toto Neorest).
Detail: Include $20–$100 for a seat and $100–$300 for pro installation if needed. DIY cuts costs but risks leaks if done poorly.
Step 10: Research Brands, Reviews, and Warranties
Compare top brands and dig into feedback.
-
Kohler: Known for style and innovation (e.g., ContinuousClean).
-
Toto: Leaders in efficiency and flush performance (e.g., Eco UltraMax).
-
American Standard: Affordable, reliable options (e.g., Cadet 3).
-
Warranties: Typically 1–5 years—check coverage for flush valves and ceramics.
Tip: Read reviews on retail sites like Home Depot or Amazon for real-world insights on flush power, durability, and installation quirks.
