I am planning to install a bidet. Who sells conversion kits for standard toilets?

If you have a standard toilet, you usually do not need to replace the toilet. Many companies sell retrofit bidet conversion kits, which are usually either:

• Bidet attachments — thin units that mount under your existing toilet seat and connect to the toilet’s water supply.
• Bidet toilet seats — replace your existing seat and add features like adjustable sprays, heated seats, warm water, dryers, and remotes.

Here are some common sellers and brands:

Retailers

• The Home Depot — carries many bidet attachments and seats, including models from BIO BIDET, Brondell, TUSHY, Delta, American Standard, and others.
• Lowe's — sells bidet-function toilet seats and bidet toilet products.
• Walmart — carries budget bidet attachments and seats from multiple manufacturers.
• Amazon — has a very wide selection of retrofit bidet attachments and seats.

Popular bidet conversion brands

• TUSHY — well-known under-seat bidet attachments; many models install without electricity.
• BIO BIDET — offers both simple non-electric attachments and higher-end electric bidet seats.
• Brondell — makes attachments and bidet seats designed for many standard toilets.
• LUXE Bidet — known for affordable non-electric bidet attachments.
• American Standard — sells non-electric and electric bidet seats that retrofit existing toilets.
• Kohler — offers bidet seats and integrated bidet products.

What to check before buying

1. Toilet shape: round-front vs. elongated bowl.
2. Seat mounting holes: most retrofit seats fit standard two-hole toilet mounts, but check measurements.
3. Power availability: - No outlet nearby → choose a non-electric attachment or seat.

• Outlet nearby → electric seats can add warm water, heat, dryer, and remote controls.

4. Clearance: Some toilets with very close tanks or unusual shapes may not fit certain seats.

For a first installation, a non-electric bidet attachment ($30–$100 range) is usually the simplest way to try one. A heated electric bidet seat ($200–$600+) is the more comfortable upgrade.

If you tell me your toilet brand/model (or whether it is round or elongated) and whether you want warm water, I can narrow down compatible kits.

Many retailers and specialized suppliers sell bidet conversion kits and attachments for standard toilets, ranging from simple cold-water sprayers to warm-water retrofit systems.

If you'd like, tell me:

• Do you prefer a cold-water attachment or a warm-water hookup?
• Is your toilet a one-piece or two-piece model?

I can help you choose the right kit for your setup.

Several popular brands and major retailers offer bidet conversion kits and attachments that easily retrofit onto standard round or elongated toilets. Depending on whether you want a simple mechanical attachment (no electricity required) or a full electronic bidet seat replacement, here are the top options:

Popular Bidet Brands (Direct & Online)

• TUSHY: Famous for their sleek, non-electric mechanical bidet attachments that install under your existing toilet seat in about 10 minutes . They run entirely on your home's water pressure . You can buy them directly on the TUSHY Official Website.
• Brondell: Offers everything from basic eco-seat attachments to advanced warm-water electronic bidet seats. Available on the Brondell Official Website or via major home goods retailers.
• Luxe Bidet: Known for highly-rated, affordable mechanical attachments (like the NEO series) available directly through the Luxe Bidet Store or major online marketplaces.

Major Retailers

• Mass Retailers: Target and Walmart stock affordable entry-level non-electric bidet attachments online and in select locations.
• Online Marketplaces: Amazon features the widest variety of budget-to-luxury conversion brands (Luxe, Bio Bidet, Brondell, TUSHY).

If you can share whether you prefer a non-electric mechanical attachment (simpler, cheaper) or an electric bidet seat (heated water/seat), I can help you narrow down specific model recommendations.

Yes. If you have a standard existing toilet, you usually don’t need to replace the toilet—you can add a bidet attachment underneath the existing seat. Consumer Reports notes that several well-known attachments are inexpensive and relatively easy to install.

Here are some good current options:

• TUSHY Classic 3.0 Bidet Attachment - $129.00 (TUSHY Inc)

• Brondell FreshSpa Comfort+ Bidet Attachment - $39.98 (The Home Depot)

• Bio Bidet SlimEdge Bidet Attachment - $43.99 (The Home Depot)

• LUXE Bidet NEO 185 - $49.99 (Target)

• Kohler PureWash M100 - $31.22 (The Home Depot)

• TUSHY — popular, easy-install attachments; TUSHY says its attachments fit most standard toilets.

• Brondell — offers both simple non-electric attachments and more sophisticated heated bidet seats. Its attachments are designed for standard toilets.

• Bio Bidet — good inexpensive attachments, including dual-nozzle models.

• LUXE Bidet — particularly good for a basic, inexpensive retrofit; its NEO series starts around $40.

• Kohler — also makes attachable bidet systems if you'd prefer a major plumbing-fixture brand.

What I'd recommend

If you want simple and inexpensive, I'd look at the LUXE NEO 120/185 or Brondell FreshSpa.

If you want more features and a nicer experience, consider a bidet toilet seat rather than an attachment. That replaces your existing seat and can provide heated water, a heated seat, dryer, etc.—but you'll generally need a nearby GFCI electrical outlet for the powered models.

One important thing before ordering: check whether your toilet is round or elongated and whether it is a one-piece, two-piece, or skirted toilet. Some unusual "French curve" toilets have compatibility issues.

If you tell me your toilet brand/model (or send me a photo of the toilet), I can narrow it down to the conversion kits that will fit it.

You can purchase bidet conversion kits for standard toilets from major home improvement centers, mass retailers, and online marketplaces.

Concrete Product Examples

Add to list A budget-friendly mechanical conversion system that allows for both hot and cold water mixing without using electricity. It features enamel-coated hardware to prevent rust.

Add to list An ultra-thin (0.24 inches) mechanical attachment that fits standard two-piece toilets without causing a seat gap. It includes dual nozzles for rear and feminine washes, built-in splash guards, and a durable braided stainless steel water hose.

Add to list A highly rated, entry-level ambient water attachment. It installs in minutes under your existing seat using basic household tools and features adjustable water pressure dials.

To help you narrow down the best choice, what shape is your toilet bowl (round or elongated), and do you have an electrical outlet near the toilet?

Yes. For a standard existing toilet, you generally want a bidet attachment or a non-electric bidet seat rather than a separate bidet fixture. These install under/replace the existing toilet seat and connect to the toilet’s water supply. Brondell says its standard attachments can typically be installed in about 20 minutes.

What I'd recommend

For a first installation, I'd choose a non-electric under-seat attachment. They're inexpensive, don't require an electrical outlet, and generally take around 10–20 minutes to install. Brondell says its attachments come with the parts needed for a standard installation.

Before ordering, check whether your toilet is round or elongated and whether it's a standard two-piece toilet. Also check clearance around the tank and seat bolts—some toilets with curved/skirted designs can require special hardware.

If you tell me whether your toilet is round or elongated and your approximate budget (e.g. under $50, $100, or $200), I can narrow it down to the 2–3 best choices.

Where to Buy Them

You can purchase these conversion kits from major home improvement retailers, big-box stores, pharmacies, and online direct-to-consumer storefronts:

• Home improvement centers like The Home Depot and Lowe's stock a robust selection in-store and online.
• General retailers like Target and Walmart carry various entry-level and mid-tier models.
• Specialized online vendors like BidetKing offer curated selections and technical support for specific toilet compatibilities.

If you'd like to narrow down your choices, let me know:

• Do you prefer a non-electric attachment or a heated electric bidet seat?
• Do you have access to a hot water line under your sink if you want warm water?

Yes. What you’re looking for is usually called a bidet attachment, bidet toilet-seat attachment, or bidet conversion kit. These retrofit your existing toilet rather than requiring a new toilet.

Major places that sell them

• The Home Depot — carries a large selection, including Brondell, Bio Bidet, Kohler, TUSHY, and others. Current listings include basic non-electric attachments around $40–$70.

• Lowe's — carries Brondell, TUSHY, Kohler, HOROW, and other bidet attachments.

• Walmart — sells inexpensive retrofit attachments, including Brondell and Mainstays.

• Target — carries Brondell and Luxe Bidet attachments.

• Ace Hardware — also carries Brondell retrofit attachments.

A few types to consider

Basic cold-water attachment:
This is the simplest and least expensive. It mounts underneath your existing toilet seat and connects to the toilet's water supply.

Warm-water attachment:
Uses a connection to your home's hot-water line, so you get temperature adjustment without electricity.

Electric bidet seat:
Replaces your existing toilet seat and can provide heated water, heated seat, dryer, remote control, etc. These cost considerably more and require an electrical outlet near the toilet.

For example, a basic Brondell attachment is currently around $45, while a TUSHY warm-water attachment is around $149.

One important thing: check your toilet's shape and dimensions before buying. Brondell, for example, recommends checking the spacing between the seat bolts and clearance between the bolts and toilet tank; certain one-piece, skirted, or French-curve toilets can require additional hardware.

If you tell me whether your toilet is round or elongated, and whether you want cold or warm water, I can narrow it down to a few good conversion kits and current prices.

A wide variety of home improvement retailers, specialty plumbing brands, and online marketplaces sell bidet conversion kits and non-electric attachments designed to fit standard round or elongated toilets for $25 to $100 on average. Major vendors carrying these mechanical retrofit systems include Home Depot, Lowe's, Walmart , and online plumbing suppliers like NuFlush and Medex Supply.
