What Type of Bidet Do You Have? Three Options
Before buying, identify your situation:
| Type | What It Is | Install Time | Price Range | Requires |
|---|---|---|---|---|
| Bidet Attachment | Thin plate that slides under the toilet seat. Cold water only (or cold + warm). | 10-15 minutes | $30-$100 | Nothing special |
| Bidet Seat | Full toilet seat replacement with built-in bidet nozzle. | 20-30 minutes | $100-$600+ | Outlet nearby for electric models |
| Handheld Sprayer | Sprayer mounted next to the toilet on the wall. | 20-30 minutes | $20-$50 | Drill, mounting |
For 90% of people doing their first install: get a bidet attachment. It's the easiest, cheapest, and works on any toilet without needing an electrical outlet.
How We Chose
We researched dozens of options, analyzed thousands of verified reviews on Amazon and Reddit, and cross-referenced expert recommendations from Wirecutter long-term testing, RTINGS.com measurements, and Consumer Reports. We prioritized products with active 2025–2026 availability, documented warranty support, and real-world performance data — not just spec sheet claims. Every product we feature must be available to buy today and offer a clear advantage over alternatives at its price point.
Check These Before You Buy
- Toilet shape: Measure your toilet bowl from the mounting holes to the front rim. Round toilets = 16.5 inches. Elongated = 18.5 inches. Most bidets specify compatibility. When in doubt, elongated seat attachments fit both with a slight overhang that doesn't affect function.
- Water shutoff valve: Look behind the toilet, near the floor, for a small oval handle or knob on a braided hose. Turn it clockwise to confirm it works. If it hasn't been touched in 20 years and won't turn, call a plumber before you buy a bidet.
- Hot water connection (heated seat/water bidets): Electric seat bidets need a grounded three-prong outlet within 4 feet of the toilet. No outlet? Get a cold-water attachment instead.
Tools You Need
- Adjustable wrench (or channel-lock pliers)
- Old towel or rag
- Teflon tape (plumber's tape) -- about $2 at any hardware store
- That's it. No drill, no cutting, no soldering.
Step-by-Step: Installing a Bidet Attachment (Cold Water)
Video for this section: LUXE Bidet official installation video -- shows exactly how the T-valve connects in real time on a real toilet.
Step 1: Turn Off the Water (30 seconds)
Find the water shutoff valve behind the toilet, low on the wall. Turn clockwise until it stops. Flush the toilet to empty the tank. Flush again to confirm the tank doesn't refill. What it looks like when off: The toilet bowl water level drops slightly after flushing and the tank stays empty. If water continues trickling in, the valve isn't fully closed -- turn harder or call a plumber.
Lay your towel on the floor behind the toilet to catch drips.
Step 2: Disconnect the Water Supply Hose (2 minutes)
The braided metal or white plastic hose runs from the shutoff valve up to the bottom of the toilet tank. Using your adjustable wrench, grip the large nut at the bottom of the tank and turn counterclockwise. Have your towel ready -- a few cups of water will spill. What it looks like: The nut turns freely after 3-4 turns, then the hose pulls away. A small amount of water drips from both the hose end and the tank fitting. This is normal -- it's just residual water from the tank.
Step 3: Attach the T-Valve (3 minutes)
The T-valve (included with every bidet attachment) is a Y-shaped brass fitting that splits the water supply -- one branch goes to the toilet tank, the other goes to the bidet. Wrap 2-3 layers of Teflon tape clockwise around the threads of the tank's inlet fitting before attaching the T-valve. This is the step most beginners skip, and it causes nearly every post-install drip.
Thread the T-valve onto the tank inlet fitting by hand first (clockwise), then tighten with the wrench. One to one-and-a-half turns past hand-tight is correct. Do not overtighten: cracking a plastic fitting means a $3 part and a trip to the hardware store. Thread the original supply hose back onto the bottom of the T-valve and tighten similarly.
What it looks like when done right: The T-valve sits straight, both connections are finger-tight plus about a quarter turn. The third port (the bidet supply port) is pointing toward the bidet.
Step 4: Remove the Toilet Seat (2 minutes)
Look underneath the toilet bowl at the back for two plastic nuts holding the seat bolts. Unscrew them counterclockwise by hand or with the wrench. Lift the seat and lid straight up and off. What it looks like: Two round plastic caps at the back of the bowl hide the bolts underneath. Pop the caps off, unscrew the nuts, and the whole seat lifts free.
Step 5: Position the Bidet Plate and Reinstall the Seat (3 minutes)
Slide the bidet attachment plate under the toilet seat mounting position, aligning its holes with the bolt holes in the toilet bowl. The nozzle should face toward the back of the bowl. Reinstall the seat on top of the bidet plate, threading the bolts through both. Tighten the nuts -- snug but not cranked down. Test that the seat doesn't wobble.
Step 6: Connect the Bidet Water Supply Hose (2 minutes)
The bidet attachment comes with a braided supply hose with fittings at each end. Connect one end to the bidet's inlet port on the attachment (usually on the right side) and the other end to the open port on the T-valve. Hand-tighten only -- these are usually plastic fittings with rubber washers inside that seal when compressed. Do not use Teflon tape on these connections -- the rubber washer provides the seal. Teflon tape will prevent the washer from seating correctly.

The LUXE Bidet Neo 120 is the correct starting point for bidet adoption in North American households — it attaches between the toilet seat and bowl using the existing water supply connection, requires no electrical outlet, and costs under $35. The single cold-water nozzle retracts when not in use and self-cleans before each use. Installation takes 15-20 minutes with a screwdriver and adjustable wrench. The pressure control dial adjusts from a gentle rinse to a more assertive clean. Compared to the LUXE Bidet Elite 3 in this lineup, the Neo 120 uses a plastic nozzle rather than stainless steel — functionally equivalent for most users, with the Elite 3 offering stainless steel for users who prefer a more durable or hygienic-feeling nozzle material. Versus the TUSHY Classic 3.0, LUXE Neo 120 is less expensive and the market category leader by review volume — the TUSHY has better design aesthetics for modern bathrooms. Both the LUXE and TUSHY mechanical attachments serve as the entry tier compared to the Brondell Swash and TUSHY Ace seat upgrades, which replace the toilet seat entirely and add heated seat, warm water, and remote control. For a first bidet purchase with zero commitment required, the Neo 120 eliminates every barrier to trying bidet use. Best for first-time bidet users who want the lowest-cost, lowest-commitment entry to the category.
TUSHY Classic 3.0 Bidet Attachment
“The TUSHY Classic 3.0 is the most design-forward mechanical bidet in this guide. It cleans effectively and installs quickly, but its main differentiator is aesthetics—it looks intentional in a modern ”

The TUSHY Classic 3.0 is the design-forward option in the mechanical bidet attachment category — TUSHY built their brand on making bidets accessible and aesthetically intentional in bathrooms where prior bidet attachments looked utilitarian and out of place. The Classic 3.0 fits beneath a standard toilet seat with a clean profile, available in multiple color options that coordinate with modern bathroom hardware finishes. The pressure and angle controls are accessible and intuitive. Functionally, the Classic 3.0 performs equivalently to the LUXE Neo 120 and Elite 3 — all three are cold-water mechanical attachments with similar cleaning performance. The TUSHY's differentiation is visual integration and brand experience. At a slightly higher price than the LUXE Neo 120, you are paying for the design quality and the TUSHY brand. Compared to the Brondell Swash 300 and TUSHY Ace 2.0 full seat replacements in this lineup, the Classic 3.0 is a mechanical attachment only — it does not include heated seat or warm water, which are the features that make the full seat upgrades worth the higher cost. For buyers who want a bidet that looks intentional rather than functional-only and are fine with cold water, the TUSHY Classic 3.0 is the right choice. Best for style-conscious buyers remodeling or updating a bathroom where the bidet attachment needs to look as designed as the rest of the space.

The Brondell Swash 300 is the category step-change in this bidet guide — where the LUXE and TUSHY mechanical attachments clip under your existing toilet seat for cold-water cleaning, the Swash 300 replaces the toilet seat entirely and adds heated seat, remote-controlled warm water wash with adjustable temperature and pressure, and a quiet-close lid. For users who have tried a cold-water bidet attachment and want the full experience without an expensive Japanese-style integrated toilet, the Swash 300 is the bridge product. The warm water wash is the single largest comfort improvement over cold-water attachments — particularly important in winter months when cold-water bidets are used reluctantly. The remote control allows adjustment without reaching around the toilet. Installation requires a nearby electrical outlet for the heated functions. Compared to the TUSHY Ace 2.0 below it in this lineup, the Swash 300 is by Brondell, a brand with longer-standing US market presence in bidet seats; the Ace 2.0 is TUSHY's equivalent entry. Both add heated seat and warm water at comparable price points. The Swash 300 has more user reviews and an established reliability track record. Versus the mechanical attachments on this page, the Swash 300 is significantly more expensive but provides the features (warm water, heated seat) that make daily bidet use consistently pleasant regardless of season. Best for users who want the full bidet seat experience without a full bathroom remodel.
TUSHY Ace 2.0 Electric Bidet Seat Elongated with Heated Seat and Warm Water
“Best premium TUSHY — electric heated seat and dryer for the full bidet experience.”

- Heated seat adjustable to 5 temperatures
- Warm air dryer

- Remote control included

The TUSHY Ace 2.0 is the premium electric bidet seat in this guide — a full toilet seat replacement with heated seat, warm water wash with adjustable temperature, an air dryer, and a deodorizer. It represents the closest approximation to a Japanese-style Washlet available as a retrofit product without professional plumbing. The heated seat is the winter comfort feature that makes the difference between a bidet you use occasionally and one you prefer to alternatives: cold bidet seats in cold bathrooms are a significant barrier to adoption that the Ace 2.0 eliminates. The air dryer reduces or eliminates toilet paper use for drying. The deodorizer addresses the most private bathroom odor concern. Compared to the Brondell Swash 300 in this lineup, both products are electric bidet seats at a similar price tier — TUSHY is the more marketing-forward brand with a strong direct-to-consumer presence; Brondell has a longer track record in the North American bidet market. Real-world performance between the two is comparable. Versus the mechanical attachments (LUXE, TUSHY Classic) earlier in this lineup, the Ace 2.0 is significantly more expensive and requires an electrical outlet, but the heated seat and warm water make daily use substantially more comfortable. Best for users who tried a cold-water bidet and want the full electric seat experience, or anyone who wants maximum bidet functionality in a single retrofit product.
