Does Round or Elongated Cost More? What Four Listings Actually Show

Shoppers measuring their toilet bowl before buying an electric bidet seat usually assume one thing without ever checking it: that the round version, being physically smaller, should cost less than the elongated one. It's an intuitive guess — less plastic, less shell, less seat. mijashy's catalogue appears to confirm it. The brand's round electric bidet seat lists at $139.99, and its elongated model in the same line lists at $169.99 — a flat $30 gap, round coming in cheaper, exactly as the intuition predicts.

Then IYTATA's catalogue breaks the pattern completely. Its round model and its elongated model, both electric, both from the same "102" line, both list at the identical $169.99. No discount for the smaller bowl. No premium for the larger one. Put the two brands side by side and you get two different, equally real answers to the same question — which means the question "does round cost less?" doesn't actually have one answer. It has a per-brand answer, and we pulled the two clearest examples in our catalogue to show exactly what that looks like in practice.

One honest note before we get into the numbers: everything below comes from reading each of these four Amazon listing titles word for word and comparing what's printed against the price charged. We don't run a testing lab, haven't had these seats in a bathroom, and aren't claiming to know what's inside either shell beyond what each seller chose to state. Where a listing doesn't name something, we say so instead of guessing.

Why a smaller bowl shouldn't automatically mean a smaller price

A round bowl is genuinely smaller than an elongated one — typically a couple of inches shorter front to back — so the assumption that a round seat uses less material isn't wrong on its face. But an electric bidet seat isn't priced like a sheet of plastic sold by the square inch. The bulk of what a brand is charging for sits inside the shell: a water heater, a pump, motors that move and oscillate the wand, a control board, a remote or side panel, and on fuller-featured models an air dryer, a deodorizer and a night light. None of those components get smaller or cheaper just because the outer shell is a few inches shorter. The shell itself — the molded lid and seat you actually sit on — is a small fraction of a $140–$170 bill of materials.

That's the reason bowl shape, on its own, is a weak predictor of price across this category, and it's worth checking against real listings rather than assuming. We've made a version of this point before: our look at MIJIC vs KioGro's identical $130 price bracket found that two sellers in the same bracket can print wildly different numbers of named features, and our breakdown of Delta's Refresh Standard vs Premium tiers found a $25.50 gap that tracked one specific added feature, not a size change at all. mijashy and IYTATA give us the cleanest version of the same test applied specifically to bowl shape: one brand's pricing moves with it, the other brand's doesn't move at all.

Lined up this way, a pattern jumps out that has nothing to do with bowl shape directly: within each brand, the listing with the shorter named-feature list is the cheaper one, and the listing with the longer named-feature list is the pricier one — or, in IYTATA's case, the two lists are so close in length that the price doesn't move at all. Bowl shape and feature count happen to travel together in mijashy's catalogue. They don't in IYTATA's. That distinction is the whole article, and it's worth walking through each pair on its own.

Read mijashy's two titles exactly as written. The round model's full title is: "mijashy Electric Bidet Toilet Seat, Round, Warm Water, Heated Seat." Strip out "Electric" and "Round" as descriptors rather than features, and two functional claims remain — warm water and a heated seat. The elongated model's title reads: "mijashy Bidet Toilet Seat, Elongated, Electric, Warm Water, Air Dryer, Heated Seat and Slow Close Lid, Front and Rear Wash, Night light, Wireless Remote, 102 (Elongated)." The same two basics are in there, plus five more: an air dryer, a slow-close lid, front-and-rear wash, a night light, and a wireless remote. That's a $30 price gap sitting on top of a five-item gap in what the two titles actually claim.

Worth flagging honestly: the elongated listing carries a model tag, "102 (Elongated)," that ties it to a specific numbered line. The round listing's title carries no model number at all — just "Round." So while we're calling this "the same model line" because both are mijashy electric seats built around the identical warm-water-and-heated-seat core, that framing rests on the shared brand and shared basics, not on a printed model code linking the two the way IYTATA's titles do for its own pair, below. If a visible "same SKU family" guarantee matters to you, mijashy's own listing titles don't hand you one for the round model — the full Amazon listing page is where to check further, not this comparison.

What we can say cleanly: mijashy's $30 gap tracks almost exactly with its five-item feature-naming gap. Whether the round shell is also missing a night light and a wireless remote in reality, or simply wasn't written into that particular title, isn't something either title answers on its own — a shorter title states less, it doesn't necessarily prove less. But as a pricing pattern, mijashy's round model is priced like the leaner listing it reads as, not like a discount on the same fully-featured seat in a smaller shape.

IYTATA's two titles are the cleanest same-brand, same-price comparison in this pair. The round model's full title: "IYTATA Electric Bidet Toilet Seat, Warm Water with Air Dryer, Heated Seat and Slow Close Lid, Front and Rear Wash, LED Nightlight, Wireless Remote, Round, 102D." The elongated model's full title: "IYTATA Electric Bidet Toilet Seat, Elongated, Warm Water with Air Dryer, Heated Seat and Slow Close Lid, Adjustable Water Temperature, Front and Rear Wash, LED Nightlight, Wireless Remote, 102." Line them up word for word and seven functional claims appear on both: warm water, air dryer, heated seat, slow-close lid, front-and-rear wash, LED nightlight, wireless remote. The only item that appears on one and not the other is "Adjustable Water Temperature," named on the elongated listing alone.

Unlike mijashy, IYTATA's two model numbers make the same-line relationship explicit rather than implied: the round model is tagged "102D," the elongated model is tagged "102." Same base number, a letter appended for the round variant — about as close to a printed guarantee that these are two bowl-shape versions of one product as a listing title gets in this catalogue. And despite the elongated version naming one more feature than the round one, IYTATA charged exactly $169.99 for both. No markup for the extra named item, no markdown for the smaller shell.

We'll flag one coincidence without reading too much into it: mijashy's elongated listing is also tagged "102," the same number IYTATA uses for its own elongated model. Whether that reflects a shared OEM shell sold under two different storefront names, or is simply an unrelated model number two sellers happened to pick, isn't something either title tells us — we have no teardown and won't guess at a shared manufacturer from a matching number alone. It's worth knowing the coincidence exists, and worth not treating it as proof of anything beyond that.

Shop the listing, not the bowl shape

The honest takeaway from these four listings isn't "round is cheaper" or "shape doesn't matter." It's that bowl shape is not, by itself, a pricing variable you can rely on across brands — it's a variable some brands choose to price around and others don't, and the only way to know which kind of brand you're buying from is to check the two specific listings in front of you. mijashy's $30 gap looks like confirmation of the "smaller equals cheaper" instinct right up until you check IYTATA, where the exact same instinct would cost you nothing to act on, because IYTATA never built shape into its price in the first place.

If you're shopping by bowl shape because that's the fit constraint your bathroom hands you — which, practically, it usually is — the useful move is to stop assuming a discount or a premium exists for your shape and instead compare what each brand's specific listing names at its specific price, the same way we compared whether a second nozzle is worth paying for or whether a fancier-sounding wash mode reflects anything different underneath. A round bowl doesn't owe you $30 off. It also doesn't owe anyone else $30 more. What you're actually paying for, in both of these catalogues, is whatever that brand's title decided to name — and bowl shape, on its own, turned out to predict almost none of it.

One more number worth sitting with: of the three elongated-or-round seats priced at $169.99 here, two are from different brands and one is round. Shape told you nothing about which of those three would cost the same as the other two. The named feature list told you almost everything.
