Key Takeaways
Compare both quotes against one scope, one operating profile and one time horizon.
Article 68 of Directive 2014/24/EU separates four useful life-cycle cost groups.
A blank price is an unresolved cost. It isn't a zero.
Name the exact heater, controls, stones, electrical work and commissioning in each quote.
Keep factory work, transport, offloading and site work on separate lines.
Make every supplier assumption traceable to a drawing, manual, schedule or written exclusion.
Two outdoor sauna quotes can show different totals and still describe different jobs. We assemble and check saunas before shipment in Klaipėda, so we see exactly where factory scope ends and site scope begins. By the end of this article, you'll have one comparison sheet that exposes missing work before a procurement committee compares price.
A European hotel should compare two outdoor sauna quotes only after both suppliers price the same life cycle, not merely the same cabin. Put acquisition, transport, offloading, site works, electrical installation, commissioning, energy, maintenance, downtime and end-of-life on one sheet. Use the same operating profile and evidence rules for both suppliers. Any blank stays blank. It doesn't become zero. The lower headline price wins only after every included, excluded and unpriced line is visible.
A sauna quotation usually stops where the supplier's responsibility stops. The hotel project doesn't.
That distinction matters before anyone compares totals. One supplier may quote a completed cabin. Another may quote a kit, a heater and a drawing. Both documents can be accurate. They aren't comparable.
There is a useful structure already written into European procurement law. Article 68 of Directive 2014/24/EU groups life-cycle costs into acquisition, use, maintenance and end-of-life. It also says the buyer should state the data suppliers must provide and the method used to calculate the result.
A private hotel isn't automatically bound by public procurement rules. The structure is still good. It forces the buyer to publish the measuring stick before seeing which supplier it favours.
Now bring that logic into the sauna quote.
The current HUUM electric-heater support guidance shows why a product name isn't enough. For several heater families, the delivery set excludes stones, the controller and the power cable. HUUM also states that a certified electrician must complete the electrical work under local rules. A line reading “HUUM heater included” leaves several costs unanswered.
Our own cube-sauna specification creates a different hand-off. The sauna is delivered fully assembled, while the buyer arranges the local crane or heavy-duty forklift for offloading. Again, the product statement can be complete while the site budget remains incomplete.
This isn't a trick in either quote. It's a boundary.
Your comparison sheet must show it.
Use one row for every hand-off. Don't bury three trades inside “installation”. The person who owns a row must be named before contract award.
Cost line | Supplier A | Supplier B | Evidence required | Hotel-side owner |
|---|---|---|---|---|
Cabin and internal fit-out | Included / excluded / unpriced | Included / excluded / unpriced | Signed specification and drawings | Procurement |
Heater, controller, stones and accessories | Exact models and delivery-set list | Spa operations | ||
Factory assembly and pre-shipment check | Inspection record and scope statement | Project manager | ||
Freight to the property | Incoterm, route and delivery point | Logistics | ||
Offloading and final positioning | Weight, lifting points and access plan | Main contractor | ||
Base, drainage and surrounding works | Site drawing and local contractor price | Architect | ||
Electrical supply and final connection | Load data, cable route and electrician quote | Electrical contractor | ||
Commissioning and handover | Test record, manuals and staff briefing | Engineering | ||
Planned energy use | Shared operating profile and calculation | Finance | ||
Maintenance, consumables and spare parts | Model-specific schedule and parts list | Engineering | ||
Downtime allowance | Hotel's own disruption assumptions | Operations | ||
End-of-life work | Removal responsibility and stated assumptions | Asset manager |
The empty cells are deliberate. They stop invented precision.
If a supplier can't price a local trade, mark the line “buyer to price”. Then obtain that local price before comparing totals. Never move an unknown into an “included” subtotal because someone expects it to be small.
Start with the result the hotel needs, not the product each supplier wants to sell. Define intended use, location, guest capacity, operating pattern, access route, heater type and the documents required at handover.
Here's how you check it. Send the same one-page brief to both suppliers. If either supplier changes an assumption, record the change beside its price. Don't let assumptions disappear inside email threads.
“Included” means the signed scope names the item and the responsible party. “Excluded” means the buyer knows it must be purchased elsewhere. “Unpriced” means the project still carries uncertainty.
Here's how you check it. Ban empty cells from the approval sheet. Use one of those three labels, then attach the source page from the quotation, drawing or manual.
The factory hand-off, delivery hand-off and site hand-off are different events. A completed cabin can still need freight, lifting equipment, a prepared base and a final electrical connection.
Here's how you check it. Draw the unit's route from factory floor to operating position. Put a company name beside every lift, connection and inspection. Our separate guide on whether an outdoor sauna should arrive assembled or flat-pack helps define that first boundary.
Don't accept two energy figures calculated from different guest patterns. Choose one operating profile and apply it to both designs.
Here's how you check it. Ask for the exact heater model and rated input. Then show the buyer's arithmetic:
comparison energy input = rated kW × planned heated hours × local price per kWh
Label this as a comparison scenario, not measured consumption. Thermostat cycling, glass area, weather, ventilation and user behaviour can change real use. If a supplier has comparable meter data, keep the raw record and its operating conditions beside the estimate.
Maintenance is planned work. Downtime is operational exposure. Combining them hides both.
Here's how you check it. Require the schedule for the exact heater and cabin, plus a list of consumables and replaceable parts. HUUM's current guidance, for example, tells owners to check stone condition once a year or after 300 heating hours. That isn't a universal rule for every heater. It proves the interval must come from the chosen model's current instructions.
For downtime, use the hotel's own numbers. Count internal labour, external call-out, guest recovery and any closed-booking effect that management is prepared to defend. If the property assigns no monetary impact, record that decision explicitly. Don't let the supplier invent it.
The winning offer should leave a small evidence pack, not just a lower total. It needs enough information for a different employee to understand the decision a year later.
Ask each supplier to return this block in writing:
Cabin model and revision:
Exact heater and controller models:
Items supplied loose or excluded:
Factory assembly completed: yes / no / partial
Delivery point and freight term:
Offloading responsibility:
Required site works:
Required electrical works:
Commissioning responsibility:
Maintenance documents attached:
Consumables and recommended spare parts:
Warranty scope and exclusions:
Removal responsibility at end of use:
Every unpriced assumption:
Then attach four things: the signed specification, installation drawing, current manuals and responsibility schedule. A brochure can introduce a product. It can't close a cost line.
You don't need a complicated financial model. Take the next two quotes, add the twelve rows above and refuse to score either until every blank has an owner. The number at the bottom will finally describe the same job.
The cheapest sauna is a claim. A complete scope is evidence.
Yes. A lower quotation can remain lower after every cost line is normalised. The point isn't to favour the expensive supplier. It is to test both suppliers with the same scope, operating profile, evidence standard and time horizon before calling either one cheaper.
Use the property's approved holding or capital-planning horizon, then apply it identically to both offers. There is no honest universal period for every hotel. State the horizon, usage assumptions and replacement assumptions on the first page so finance can reproduce the result.
Yes, but label it as a buyer scenario. Use the same planned heated hours, local tariff and exact heater data for both offers. Keep measured supplier data separate unless its room, climate and operating pattern are genuinely comparable to the proposed hotel installation.
Build it from the hotel's own operations. List staff time, external call-out, guest recovery and any closed-booking effect management recognises. Use zero only when the responsible manager signs off that assumption. The supplier should provide service facts, not invent the hotel's loss.
Price work controlled by the site through local contractors: access preparation, base and drainage, lifting, electrical supply, final connection and any local approvals. The supplier must still provide the dimensions, loads, interfaces and drawings those contractors need to quote the work properly.
No. Directive 2014/24/EU governs public procurement, so its legal duties don't automatically apply to a private hotel. Its cost structure remains useful because it separates acquisition, use, maintenance and end-of-life, and requires the calculation method to be visible before offers are judged.
