NuFlush is best for budget-conscious DIY installers who need a basic conversion kit with hot/cold water connections—very affordable and easy to install, but lacks premium electric-seat features.
TUSHY fits buyers who want an easy-install, stylish attachment with self-cleaning nozzles and broad compatibility—good all-around balance but typically pricier than the most basic kits.
Brondell is the top pick when you need a low-profile/thin attachment to fit tight toilet clearances—recommended for slim designs, though not the cheapest choice compared with basic attachments.

Types of Conversion Kits
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.

You can find these at Home Depot, Lowe's, Target, Ace Hardware, Walmart, and directly from the manufacturers. For example, Home Depot currently carries Brondell, Bio Bidet and TUSHY attachments, while Lowe's carries Brondell and TUSHY.
One important thing to check before buying: measure whether your toilet is round or elongated, and check the bolt spacing/tank clearance. Brondell, for example, specifies 5¼–8 inches between mounting holes for many of its attachments.
If you tell me your toilet brand/model (or send me a photo of the toilet) and whether you want cold water, warm water, or a heated seat, I can narrow this down to the 2–3 kits that will fit your toilet best.
Yes. If you have a normal existing toilet, you have several good retrofit options. These are usually called bidet attachments or bidet toilet seats.

If you want warm water without electricity, there are options such as the TUSHY Spa 3.0 or LUXE NEO 320, but they require connecting to the sink's hot-water supply.
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.

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.

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.

Before buying, check whether your toilet is round or elongated and whether it has enough clearance around the seat mounting bolts. Some specialty toilets—particularly skirted, one-piece, or French-curve designs—can require additional hardware.
