Kornhaus Romanshorn

The Vertragsbestimmungen und Kundeninformation, the contract terms every Kornhaus Romanshorn booking is made under, states the building's one hard limit in four words: "Im Kornhaus ist keine Küche vorhanden," there is no kitchen in the Kornhaus. That single sentence explains most of what follows. The building is a heritage-listed former grain warehouse on the Romanshorn harbour front, described on the operator's own homepage as a structure that "im 19. Jahrhundert als Getreidespeicher diente," served as a grain store in the 19th century, before being converted, the same site says, "nach einem mehrjährigen Umbau," after a multi-year renovation, into what it now calls a first-class event location. What that renovation actually produced is three floors of raw event space, each rented by the hour, with everything a wedding needs beyond four walls and a roof, the kitchen included, either billed as a separate item or left for the couple to arrange themselves.

Three rented floors, priced by the hour

The wedding page names two of the building's three rooms, Kornsaal and Kornspeicher; the third, Kleines Kornlager, sits on the general rooms list rather than the wedding page itself. Each room's own facts page gives a size, a capacity and a flat hourly tariff, none of it wedding-specific. The Kornsaal runs 340 m² with a 4 m ceiling, holds up to 180 people, seats 120 at round eight-person tables, and comes fitted with a projector and screen, a video wall and sound equipment; renting it costs CHF 2'400.00 for up to 8 hours, CHF 2'900.00 for up to 12 hours, and CHF 500.00 for every further 4 hours, with setup time already counted against the clock. The Kornspeicher costs the same, CHF 2'400.00 for 8 hours and CHF 2'900.00 for 12, but is a different kind of room: 710 m² with a 5.10 m ceiling, seating up to 400 at long tables, with a CHF 15.00-per-person surcharge added above 240 guests. That 400-person figure runs well past the venue's own homepage pitch, which advertises the whole property for "bis zu 280 Gästen," up to 280 guests; the Kornspeicher's own facts page is the more detailed of the two documents, and the number used here. The smallest room, Kleines Kornlager, is 110 m² with two ceiling heights, 5.10 m and 2.30 m, fitted only with a projector, and holds 50 people standing or 10 seated at a block table; it rents for CHF 300.00 up to 4 hours, CHF 400.00 up to 8, and CHF 500.00 up to 12.

The room the operator calls "industrial" has no lights or sound built in

The Kornspeicher is the room the operator's own copy sells hardest on its history: "Der Kornspeicher überzeugt durch sein industrielles Ambiente mit historischer Decke, alten Säulen und grossen Sprossentüren mit Sicht auf das Hafenbecken," the Kornspeicher wins guests over with its industrial ambience, historic ceiling, old columns and large mullioned doors looking onto the harbour basin. It is also, by that same room's own facts sheet, the one of the three with no built-in lighting or sound system at all: "Technik: Licht- und Tontechnik nicht vorhanden." A couple booking the exposed beams and old columns for 400 guests is booking the room that, on the operator's own account, arrives with the least technical infrastructure of the three; the projector, video wall and house sound stay in the smaller Kornsaal.

No kitchen, so catering runs through the operator or costs extra to leave

The missing kitchen sets up everything the terms document says about food. "Das Catering ist grundsätzlich über die SBS zu beziehen," catering must generally be sourced through SBS, the Schweizerische Bodensee-Schifffahrt AG, the company that leases and runs the Kornhaus's event and gastronomy space: "Die SBS ist Pächterin der Event- und Gastronomieflächen im Kornhaus." A couple can bring an outside caterer only as an exception, and only by paying what the document calls a Gastronomieablöse, a catering buyout, of CHF 18.50 per person. Even then, "die Benutzung von vorhandenem Inventar, einem Teil der Infrastruktur und Reinigung sind in der Gastronomieablösesumme nicht enthalten," use of the existing inventory, part of the infrastructure and cleaning are not included in that buyout, and an SBS staff member has to be present throughout, billed separately at CHF 65.00 an hour. What an outside caterer gets on site is a prep room, not a kitchen: "Dem externen Caterer steht ein Vorbereitungsraum zur Verfügung," and cooking itself is barred inside the building, "in den Innenräumlichkeiten darf nicht gekocht werden." Refrigeration, crockery, cutlery, glassware and table linen are all left to the customer or the outside caterer to bring in.

A menu that names itself after the company's other business

Staying with SBS's own kitchen turns up a detail that has nothing to do with grain storage and everything to do with the company running the building. The fixed event menu SBS publishes for Kornhaus bookings has five tiers, and every one is named for a role or a fitting on a ship: a Matrosenmenü, sailor's menu, at CHF 39.50 per person (the vegetarian version costs the same); a Kapitänsmenü, captain's menu, at CHF 56.50 (CHF 41.00 vegetarian); a Schiffermenü, boatman's menu, at CHF 60.50 (CHF 48.00 vegetarian); a Bullaugenmenü, porthole menu, at CHF 74.00 (CHF 56.00 vegetarian); and an Ankermenü, anchor menu, topping the list at CHF 82.00 per person (CHF 64.00 vegetarian). A couple who brings their own wine instead of ordering from SBS's own list pays a corkage fee of CHF 30.00 per 75 cl bottle or CHF 20.00 per 50 cl bottle, covering glass rental, service and washing up; an outside wedding cake costs CHF 3.50 a head as a cover charge.

Furniture beyond what's in the room is billed to the couple

The room rental buys the shell and whatever furniture the Kornhaus already owns; anything else is a separate line item. "Die Bestuhlung erfolgt nach Absprache mit der SBS," seating is arranged in consultation with SBS, and if a couple wants furniture the building doesn't already stock, the terms are direct about who pays for it: "wird dieses extern angemietet," it gets rented in externally, "und die Kosten sind durch den Kunden zu tragen," and the costs are borne by the customer. Nothing on the site prices that external furniture rental in advance; it gets negotiated once a couple asks for something the Kornhaus doesn't have on hand.

The same events team as the boat wedding page

Kornhaus Events is not an independent business. The Impressum names the operator as Schweizerische Bodensee-Schifffahrt AG, trading here as Kornhaus Events, at the same Romanshorn address, Friedrichshafnerstrasse 55, and the same events line, +41 71 466 78 40, that answers for the company's lake cruises. The two contacts named on the Kornhaus wedding page, "Ihr Eventteam: Belma Selman, Flavia Scandella," your event team, are the identical pair named as SBS's events team elsewhere in this guide's coverage of the company's ship weddings. The Kornhaus's own wedding page makes the link explicit rather than incidental: under a section headed "Trauung auf dem See," marriage on the lake, it invites a couple to "Verbinden Sie Ihre Hochzeitsfeier im Kornhaus mit einer Trauung auf See," combine their Kornhaus reception with a ceremony on the water, sailing out for the vows and returning to the granary for dinner. That matters because the Kornhaus itself offers no ceremony of any kind: nothing on its wedding page, its room pages or its terms document mentions a registry office, a Zivilstandsamt, or any officiant. A couple wanting the ceremony and the reception in one place has to leave the building for the water, where SBS's own captain performs what the company's boat material states outright is not a legally binding ceremony, before the party returns to the Kornhaus for the meal.

A private couple prepays the full room; a Swiss company pays 30 percent

Payment terms in the contract document split by customer type. On confirmation, SBS sends an advance invoice; unless agreed otherwise, "Firmen aus der Schweiz [werden] 30% der Raummiete in Rechnung gestellt," Swiss companies are billed 30% of the room rental upfront, while "Firmen aus dem Ausland sowie Privatpersonen werden 100% der Raummiete berechnet," foreign companies and private individuals, the category a wedding couple falls into, are billed 100% of the room rental in advance. The remaining invoice, covering consumption and any extras, is generally issued after the event, due within 30 days. Cancelling a confirmed booking costs a rising share of both figures: 30% of the room rental with catering free of charge up to 90 days out, 50% of the room rental, still with free catering, from 89 to 30 days out, 80% of the room rental plus 50% of the catering from 29 to 7 days out, and 100% of both inside 7 days.

A cutoff date on the homepage, and no English version of any page

One line on the homepage sits outside all of this and is worth reading exactly as printed: "Wir nehmen Anfragen für Veranstaltungen im Kornhaus bis ausschliesslich 23.12.2026 entgegen," inquiries for events at the Kornhaus are being accepted only up to and excluding 23 December 2026. The site gives no reason for the cutoff and no other page elaborates on it; a couple planning a wedding for any date after that should raise it directly with the events team rather than assume the booking calendar simply continues past it. The whole site, terms document and menus included, runs in German only. There is no language switcher and no alternate-language version of any page, so nothing here confirms whether the events team that answers for the ferry line's bookings can run a Kornhaus wedding in English too.

Renting a floor, assembling the rest yourself

Kornhaus Romanshorn suits a couple who wants a genuinely large, honestly industrial hall on the water, columns, old ceiling timber and all, and who doesn't mind stitching the rest of the day together from a printed tariff: a room by the hour, a fixed menu named after the operator's own ships, corkage and cake fees if they bring their own, and furniture rented in on top of whatever else is missing. It won't suit a couple who wants one wedding package covering food, drink, furniture and the ceremony together, since none of that is bundled here and the ceremony itself isn't offered on site at all. What the operator sells, on its own paperwork, is square metres and hours; everything that turns that into a wedding is priced, and named, separately.
