Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.
Tushy Spa 3.0 comes out ahead by a narrow margin (4.4 vs 4.6). The gap is mostly about buyers wanting warm water without electrical install — read the strengths below before deciding.
The SimpleSpa Thinline is the entry-level pick — Brondell's bare-bones cold-water attachment at $35. Best for first-time bidet shoppers testing the concept.
The Spa 3.0 is the warm-water non-electric pick — Tushy's Spa version connects to a sink hot line for warmth without electrical install.
Cheapest pick. Aggressive spray. Cold only.
Warm water without electricity. Requires sink hot line. Cheaper than electric warm-water picks.
