KOHLER 5724-0 PureWash M250 Elongated Bidet Toliet Seat, Man

The Verdict

The KOHLER PureWash M250 sits in a weird spot: it’s priced like a premium bidet seat but stripped down to manual, non-electric basics. For some buyers, that’s exactly the point — no outlet near the toilet, no complex wiring, no smart app nonsense. For others, it’ll feel like paying luxury money for a plastic knob and a hose. Here’s who should actually buy it.

What’s in the box

You get the elongated seat assembly, a metal mounting bracket with bolts, the T-valve cold water adapter, a 3-foot supply hose, and a clearly written install manual. Note what’s not included: the hot water T-adapter kit for the warm water feature. That’s a $15–25 add-on you’ll need to buy separately if you want anything other than cold water. The seat itself is compact — about 20.5 inches long, 14.2 inches wide — with a low-profile design that doesn’t look like a hospital appliance.

Installation: plan for an hour, not 20 minutes

Mounting the seat is genuinely easy. The bracket slides into standard toilet bolt holes (5.5-inch spread fits nearly all American toilets), and the seat clicks on with a satisfying lock. The cold water hookup is straightforward: shut off the toilet supply, thread on the T-valve, connect the hose. But here’s the catch — the warm water feature requires running a line from your sink’s hot water supply under the vanity. That’s a second shutoff valve, a T-adapter, and potentially drilling through cabinet or floor. If you’re not handy with plumbing, budget for a plumber or just run it cold-only.

Real-world performance

The dual stainless steel nozzles — one for rear wash, one for front — extend and retract smoothly. Water pressure is adjustable via a dial on the right side of the seat, and you can control spray position with a slider. Users consistently praise the cleaning power: “First bidet I’ve owned that actually feels like it gets you clean without a second pass of toilet paper,” one verified reviewer noted. Another wrote, “The self-cleaning wand feature is real — no residue, no spotting after months of use.”

The warm water mixing valve is the headline feature. It blends hot and cold mechanically, giving you a consistent temperature without waiting for a tank heater. But it’s only as good as your hot water supply — if your sink takes 30 seconds to run warm, you’ll get a cold blast first. Several reviewers flagged this: “Warm water took way too long to arrive, so I just use cold now.”

Where it falls short

The M250’s biggest problem is value. At its typical street price, you’re in TOTO Washlet and Bio Bidet territory — electric units with heated seats, warm air dryers, and remote controls. The M250 offers none of that. The seat is room-temperature plastic. There’s no dryer. The side knob controls work fine but feel dated. And the water pressure, while adjustable, tops out lower than electric competitors — one buyer called it “adequate but not the power-wash I was hoping for.”

Who should buy this

• The no-outlet household: If your toilet isn’t near an electrical outlet and you refuse to pay for an electrician, the M250 is a solid non-electric option.
• The warm-water purist: Anyone who’s used a $30 cold-water bidet and wants temperature control without the cost of a tank-heated electric unit.
• KOHLER loyalists: If your bathroom is already KOHLER fixtures, the design language matches, and the Quiet-Close lid is genuinely nice — it drops silently, no slam.

Skip it if you want a heated seat, a dryer, or app controls — buy an electric unit instead. Also skip it if you have no hot water line accessible under the sink; the cold-only experience isn’t worth this price.

FAQ

Q: Does this seat fit a standard toilet? A: Yes, it fits elongated bowls with the standard 5.5-inch bolt spread. It will not fit round bowls — measure your toilet from the seat bolt holes to the front rim first.

Q: Can I use it without the warm water hookup? A: Absolutely. Just connect the cold water supply. You’ll get cold washes only, but the seat functions perfectly otherwise. You can add the hot water line later.

Q: Does it need electricity at all? A: No. It’s 100% mechanical — water pressure from your supply line drives everything. If your water is shut off, it won’t work, but there’s zero power draw.

The Verdict

Buy it if you need a reliable, non-electric bidet with genuine warm water capability and you’re comfortable with the extra plumbing. The KOHLER name means the seat itself will outlast the house.

Skip it if you want modern bidet features — heated seats, dryers, remote controls — or if your bathroom lacks an accessible hot water line. You’ll be overpaying for features you can’t use.

Rating: 4.2/5 — A well-built, no-frills bidet that nails the basics but asks a premium price for a deliberately simple feature set.
