The Instrument Desk · Three Working Tools
Don't take the desk's word for it. Run the instruments.
Every number on BidetVerdict can be re-derived by hand — so we built the benches where you do it. Rebuild any flagship score from its six criteria. Answer four questions and watch the fit logic work. Price an installation line by line, from the same ledger the guides print.
Nothing here collects data. The tools run entirely in your browser — and every one of them prints its full working below, for readers whose browser runs no scripts at all.
Score explorer
Bio Bidet Bliss BB-2000 · Electric seat · Street $489–$559 (Oct 2026) · Recommended
8.8×0.22 + 8.7×0.18 + 8.5×0.18 + 7.8×0.12 + 7.8×0.14 + 9.0×0.16 = 8.50 → 8.5
Read the full scorecard — Bio Bidet Bliss BB-2000
The right-hand column is each criterion's contribution to the total — criterion score × published weight, from the methodology. If your arithmetic disagrees with ours, the scorecard is wrong and the corrections policy applies.
The full record, printed — the no-script fallback
The explorer above is an instrument, not a gate. The complete flagship record stands in print whether or not it runs:
| Model | Wash ×.22 | Hygiene ×.18 | Comfort ×.18 | Controls ×.12 | Cost ×.14 | Build ×.16 | Total |
|---|---|---|---|---|---|---|---|
| Bio Bidet Bliss BB-2000 | 8.8 | 8.7 | 8.5 | 7.8 | 7.8 | 9.0 | 8.5 |
| Brondell Swash 1400 | 8.6 | 8.8 | 8.4 | 8.0 | 7.2 | 8.4 | 8.3 |
| TOTO Washlet C5 | 8.1 | 9.2 | 8.3 | 8.4 | 6.4 | 7.9 | 8.1 |
| Luxe Bidet Neo 120 | 7.4 | 7.0 | 5.2 | 6.8 | 9.6 | 8.2 | 7.3 |
| Brondell EcoSeat 101 | 7.0 | 7.2 | 5.8 | 6.4 | 8.4 | 8.0 | 7.1 |
| Tushy Classic 3.0 | 7.2 | 7.4 | 5.4 | 7.8 | 6.2 | 7.6 | 6.9 |
The fit checker
Bowl, outlet, budget, tenure — the four facts that decide this category. The pick comes with its reasoning printed, not just its name.
The logic is the desk's published buying sequence — form, outlet, fit — applied in that order. It recommends from the scored record only; where your answers land outside the flagship six, it says so and points at the class file instead of inventing a pick.
The same checker, in print — the no-script fallback
Every branch of the checker, argued in a table. If the instrument above cannot run, nothing is lost:
| Your situation | The desk's pick | Why |
|---|---|---|
| Renting, any outlet, under $150 | Luxe Neo 120 (7.3) | Fully reversible; strongest wash-per-dollar on the record |
| Renting, budget above $150 | Tushy Classic 3.0 (6.9) | The premium attachment: angle adjustment and finish, still reversible |
| Owner, no outlet, under $150 | Luxe Neo 120 (7.3) | Cheapest honest entry; EcoSeat 101 ($90–$125) if a complete seat is preferred |
| Owner, no outlet, $150+ | Brondell EcoSeat 101 (7.1) | Dual-nozzle complete seat; no wiring, line-temperature water accepted |
| Owner, outlet, under $150 | Luxe Neo 120 (7.3), for now | No flagship electric fits the band; budget selects within a class, never between classes |
| Owner, outlet, $150–$450 | Electric class — under-$300 file | Warm water is reachable at this band, below flagship prices |
| Owner, outlet, $450+, elongated | Bio Bidet Bliss BB-2000 (8.5) | Top score on the record; 3-year full warranty |
| Owner, outlet, $450+, round | TOTO Washlet C5 (8.1) | Highest hygiene score in the file; round SW3083 named in the line |
| Bowl shape unmeasured | Any pick, provisional | Measure first — 18.5″ vs. 16.5″ — per the sizing guide |

Driven by the same ranges the installation ledger prints — device class, the outlet question, and who does the water work.
What the instruments refuse to do
None of them invents a number. The explorer recomputes published scores; the checker recommends only from the scored record and shows its logic; the calculator adds printed ledger ranges and calls the result a planning range, not a quote. A tool that hides its working is a funnel — the desk builds instruments.
