Best Toilet Repair Kits at Home Depot (2026 Reviews)

Top toilet repair kits sold at Home Depot to fix leaks, runs, and noisy fill valves

Last Updated: 2026-01-13

Toilet repair kits are one of the most cost-effective DIY plumbing purchases a homeowner can make. Whether you're dealing with a constant running toilet, a weak flush, or wobbly tank hardware, a good repair kit from Home Depot can restore reliable performance without a call-out fee. Home Depot carries a wide range of options from brands like Fluidmaster, Korky, Danco, and American Standard, so you can match parts to your toilet type and budget. When shopping at Home Depot, focus on compatibility (universal vs. brand-specific), included parts (fill valve, flapper, flush valve seat, tank bolts), and build quality (plastic vs. brass hardware). Also consider ease of installation: many kits are designed for a single-person swap without turning off the water at the main supply. This guide reviews five top kits available at Home Depot, compares price ranges and features, and offers buying and installation tips to help you choose the right repair kit for your bathroom.

Quick Summary

  • Home Depot stocks trusted brands (Fluidmaster, Korky, Danco, American Standard) with both universal and model-specific kits.
  • Look for kits that include both fill valve and flapper for the best value and fewer trips to the store.
  • Universal kits make most installs simple, but measure your tank height and mounting type to ensure fit.
  • Higher-priced kits can include brass bolts and longer warranties; budget kits are fine for basic fixes.

Buying Guide

How to Choose the Right Toilet Repair Kit

Start by identifying the problem: is the toilet running, leaking at the tank base, or not refilling properly? A running toilet often needs a new flapper or fill valve; leaks at the base may require new bolts and gaskets. Check whether your toilet is one-piece or two-piece and note the tank height and fill-valve mounting type. Home Depot’s product pages list compatibility details and usually indicate whether a kit is universal or brand-specific. If you’re unsure, universal kits like many Fluidmaster and Korky options cover most toilets and are sold at Home Depot with clear return policies. For brand-loyal solutions, choose OEM kits (for example American Standard parts) to guarantee fit. Also consider water efficiency: newer fill valves can help reduce refill volume and save on utility bills.

Key Features to Consider

Materials and durability matter: brass-plated bolts and stainless hardware resist corrosion better than plain plastic. Flapper design is important—rubber flappers seal well but degrade over time; newer polymer flappers can last longer. Adjustable fill valves are helpful because they accommodate different tank heights and provide easy water level adjustments. Also evaluate what the kit includes. The best Home Depot kits include both the fill valve and flapper plus bolts and washers to avoid multiple trips. If a kit omits bolts, you may need to buy them separately—factor that into cost comparisons. Finally, check the warranty and product reviews on Home Depot’s site to gauge real-world durability.

Installation Considerations

Most toilet repair kits are designed for DIY installation with common tools: an adjustable wrench, screwdriver, sponge, and towel. Before starting, turn off the toilet shutoff valve and drain the tank. Many Fluidmaster and Korky kits advertise tool-free adjustments or quick-connect fill valves that simplify installation for one person. Allow 30–60 minutes for a first-time install. When replacing tank bolts, seat the gasket properly to prevent leaks. If you encounter a cracked tank or corroded valve seat, stop and consult a professional—Home Depot’s in-store associates or a FindTrustedHelp plumbing pro can advise on parts or repairs beyond a kit’s scope.

Warranty and Support

Warranty coverage varies: many premium kits include 1–5 year limited warranties, while budget kits may have minimal coverage. Fluidmaster and Korky typically offer robust customer support and clear return policies through Home Depot, making claims and exchanges straightforward. Keep your Home Depot receipt or online order number to simplify any warranty process. For OEM parts like American Standard, warranty and support are often handled by the manufacturer, which is helpful if you need model-specific guidance. If you buy at a local Home Depot store, ask a plumbing associate to confirm compatibility and warranty terms before purchase.

Frequently Asked Questions

Can I use a universal repair kit on any toilet I buy at Home Depot?

Universal kits are engineered to fit most two-piece and many one-piece toilets, and Home Depot stocks several universal options that handle a wide range of tank sizes. However, some toilets—particularly one-piece models or brand-specific designs—may need OEM parts. Check the kit’s specified tank height range and mounting type. If in doubt, bring a photo or model number to Home Depot or consult FindTrustedHelp pros for confirmation.

How long does it take to install a toilet repair kit from Home Depot?

A typical install takes 30–60 minutes for a first-time DIYer. Replacing a flapper or fill valve is often quicker, while replacing tank-to-bowl bolts or swapping multiple components takes longer. Follow the included instructions and shut off the water before starting. If you hit corroded bolts or a damaged tank, the job may take longer or require professional help.

Are parts sold at Home Depot covered by warranty?

Yes—many brands sold at Home Depot, like Fluidmaster, Korky, and American Standard, offer limited warranties on parts. Coverage depends on the manufacturer and the specific kit. Keep your Home Depot purchase receipt or order number, register the product if required, and check the packaging or product page for warranty length and exclusions to simplify claims.

What should I do if my new fill valve from Home Depot still causes a running toilet?

First, confirm the fill valve height and water level are adjusted according to the instructions. Check that the flapper seats properly and that the overflow tube isn’t cracked or too short. Sometimes the flapper or seat needs additional adjustment or the chain length is incorrect. If problems persist after following install steps, contact Home Depot support or a FindTrustedHelp plumber for diagnosis—there may be a damaged flush valve seat or a crack in the tank.

Can I return a toilet repair kit to Home Depot if it doesn’t fit?

Home Depot generally accepts returns of unused products within their return window; bring your receipt or order confirmation. Opened kits may also be returnable depending on condition and local store policy. For used components, warranty claims go through the manufacturer. Contact your local Home Depot customer service for exact return steps and to confirm whether a specific item is eligible for return.

Final Thoughts

Home Depot offers a range of toilet repair kits to suit different needs: from budget-friendly Danco and Korky kits for landlords and quick fixes, to full-featured Fluidmaster kits that provide durable components and easier installation. For American Standard toilets, brand-specific kits give the best fit but cost more. If you want a single purchase that handles the most common toilet problems, the Fluidmaster 400CRP7 (editor’s pick) is a strong, reliable choice. For buyers prioritizing value without sacrificing function, the Korky 528BP is the best-value option. Before buying at Home Depot, confirm compatibility with your toilet model, measure tank height, and decide whether you want premium hardware like brass bolts. If you’re unsure, Home Depot associates and FindTrustedHelp plumbing professionals can help you select the right kit and, if needed, provide installation service. A well-chosen repair kit typically saves money and time compared with a full replacement or a service call.
