Smart Toilets and Bidet Upgrades on a Budget

The most affordable way to get smart toilet features is usually not a smart toilet at all. A smart toilet seat on the toilet you already own gives you warm-water washing, a heated seat and a dryer for far less than an integrated model. A non-electric bidet attachment costs even less. Budget integrated smart toilets do exist, but they come with trade-offs worth understanding first.

A note on this page: we don’t publish prices because they change constantly, and we don’t rate products. When you see “top-rated” on a retail listing, that reflects customer star ratings on that site, not our assessment. This guide is based on manufacturer documentation, not physical testing. See our methodology.

Below, we walk through each budget route from least to most expensive, what you get and give up, and how to judge a low-cost integrated toilet.

The four budget routes at a glance

Route	Relative cost	What you get	What you give up
Non-electric bidet attachment	Lowest	Water wash using your existing seat; no outlet needed	Usually cold water only; no heated seat or dryer
Electric smart seat (budget to mid-range)	Low to moderate	Warm-water wash, heated seat, dryer, deodorizer, remote on many models	Auto flush; needs an outlet near the toilet
Budget integrated smart toilet	Moderate	Bidet built into a new toilet; often auto flush	Brand support and features vary; full toilet replacement
Name-brand integrated smart toilet	Highest	Full automation, sanitizing systems, established support	Mostly beyond a budget

Route 1: a non-electric bidet attachment

A non-electric attachment is a thin unit that sits between your toilet and seat. It connects to the toilet’s water supply with a T-valve and sprays water when you turn a dial or lever. There’s no outlet, no wiring and very little to go wrong.

Most attachments use cold water, and they don’t heat the seat or dry you. Some connect to a sink’s hot water line for warm water, but that adds plumbing. For a renter, a guest bathroom or anyone trying bidet washing for the first time, an attachment is the lowest-risk start. Our bidet seat vs. attachment guide compares the two in depth.

Route 2: an electric smart seat on your existing toilet

This is the route most budget shoppers should consider first. An electric bidet seat replaces your current seat and adds the core smart toilet features. You keep the toilet, so there’s no plumber, no wax ring and no disposal.

Here’s what the seats in our researched list offer, according to their manufacturers:

• Alpha JX2: tankless water heating, a heated seat with a stated 89 to 100°F range, a warm-air dryer and a backlit remote with two user presets. Alpha Bidet highlights its low stated standby power draw.
• Bio Bidet BB-2000: rear, front, vortex and turbo wash modes, a self-rinsing stainless nozzle, a dryer, a deodorizer, and both a remote and a side panel.
• Brondell Swash 1400: separate front and rear stainless nozzles, on-demand water heating, a dryer, a carbon deodorizer, an LED nightlight and a remote with two presets.

All three come in round and elongated versions. The trade-offs: you need a grounded outlet near the toilet, and seats don’t usually add auto flush. Premium seats such as the TOTO WASHLET S7A add an automatic lid, but sit well above budget territory.

Specifications from manufacturer product pages, checked November 2026. Models and availability change — confirm details on the listing before you buy. No prices are shown because they change frequently.

Route 3: a budget integrated smart toilet

Several lower-cost brands sell integrated bidet toilets, often online. They can make sense if your old toilet needs replacing anyway. HOROW is one example that publishes detailed product pages on its own store, and it shows how much features vary within a single brand:

• HOROW T05: HOROW lists a built-in tank and booster pump, four ways to flush (auto, foot touch, remote and manual), a heated seat, a warm-air dryer, an automatic deodorizer, a nightlight and a 12-inch rough-in. Power-outage flushing needs a battery pack sold separately. It lists EPA WaterSense, cUPC and ETL certifications.
• HOROW T16: HOROW lists front and rear wash with instant warm water, a heated seat, auto and remote flush, and a 12-inch rough-in. The page doesn’t list a dryer or an automatic lid.
• HOROW X70: HOROW lists rear and feminine wash, instant water heating, a warm-air dryer, an automatic lid, a nightlight and a foot-kick flush.

Several of these were marked sold out when we checked HOROW’s store in November 2026, so availability changes. We have not physically tested any of them, and we’re not ranking them; they illustrate what to compare.

How to judge a budget integrated toilet

1. Feature list, line by line. Don’t assume a “smart toilet” includes a dryer, auto lid or warm water. Confirm each one.
2. Certifications. Look for plumbing and electrical safety listings such as cUPC and ETL or UL, and WaterSense if water use matters to you. The EPA says WaterSense toilets use 1.28 gallons per flush or less.
3. Warranty and support. Check the length, what’s covered, and whether there’s a US support line and parts supply.
4. Rough-in. Most models are for a 12-inch rough-in, the most common size according to TOTO. Some brands offer 10-inch versions.
5. Electrical. Check the amperage listed and whether the cord reaches your outlet without an extension cord.
6. Water pressure and power-outage flushing. Pump and tankless designs depend on adequate supply and power. Find out how the toilet flushes in an outage.
7. Return policy. A heavy toilet is hard to send back. Know the terms before you order.

Route 4: name-brand sets as a step up

If your budget can stretch, TOTO’s WASHLET+ sets pair a TOTO toilet with a WASHLET seat and hide the power cord and water hose. TOTO lists sets starting with the WASHLET S2. It’s a cleaner look than a standalone seat with a name-brand warranty, though it costs more than the routes above.

Where to spend and where to save

On a budget, it helps to rank features by how much you’ll use them every day.

Worth paying for

• Warm water. For most people this is the difference between trying a bidet and using it daily. Tankless (instant) heating avoids running out partway through a wash.
• Adjustable pressure and position. Basic but essential for comfort.
• A self-cleaning nozzle. Common even on budget seats, and it makes upkeep easier.
• A heated seat. Especially welcome in colder climates.

Often safe to skip

• App control and ambient lighting. Nice extras, but they rarely change the daily experience.
• Many specialty spray modes. Most people settle on one or two.
• An automatic lid. Helpful for some users with limited mobility, but it adds cost and parts.

If you or someone in your home has mobility limits, the priorities shift. See our guide for older adults.

How to read “top-rated” listings

Retail star ratings can be useful, but read them carefully:

• Check how many reviews there are, not just the average.
• Read the most recent and the most critical reviews, which often reveal durability or support problems.
• Make sure reviews are for the exact model and version you’re buying.
• Be cautious when every review is five stars or reviews appear in a sudden burst.
• Look for comments about installation, warranty claims and customer service, not just first impressions.
• Remember that a high rating on one retailer doesn’t carry over to a different model number or a newer version.

Frequently asked questions

What’s the cheapest way to get a bidet?

A non-electric bidet attachment. It uses your existing seat and water supply and needs no power. You give up warm water, a heated seat and drying on most models.

Are cheap smart toilets reliable?

We can’t say from testing, because we don’t test products. What you can check is the warranty, certifications, the availability of parts and support, and recent customer reviews of the exact model.

Do budget smart toilets need an electrician?

They need a grounded, GFCI-protected outlet within cord reach. If you don’t have one, a licensed electrician should add it. Check the amperage on the product page, too.

Is a smart seat better value than a budget smart toilet?

If your toilet is in good shape, usually yes. A seat delivers the core comfort features without replacing the toilet. A budget integrated toilet makes more sense when the old toilet needs replacing anyway.

Why don’t you list prices?

Prices change too often to stay accurate. For dated price ranges based on manufacturer listings, see how much a smart toilet costs.
