The sauna houses in detail

Karibu MELO 3 sauna house complete set
- Complete set with 9 kW heater and 18 kilograms of sauna stones: no heater search, no compatibility questions
- 38 millimetre solid wall planks, sauna-grade sturdy for year-round use
- Karibu is one of the most established German suppliers of garden and sauna houses
- The 9 kW heater requires a 400-volt connection, so a qualified electrician needs to be part of the budget

Karibu garden sauna with anteroom
- Anteroom as a wind-protected changing area and storage space: this is what makes winter use really comfortable
- Two loungers and, according to the manufacturer, space for two to four people
- 9 kW heater with external control is already included in the set
- Bronzed glass door gives the house a high-quality appearance
- At 396 x 225 centimetres, the house needs serious space in the garden and a correspondingly large foundation

Karibu sauna house MELO 3 without heater
- Same 38 millimetre house as our favourite, but without a heater: you choose the technology and control yourself
- Untreated wood gives you complete freedom with stain and colour shade
- Ideal if you already own a heater or want to invest in a better model
- Heater, stones and connection come on top, and for many the complete set works out better in the end

Karibu garden sauna 195.6 x 189.9 cm
- Just under two by two metres of footprint: fits in smaller gardens and on existing paved areas too
- Solid spruce and a 9 kW heater: a full-fledged sauna house despite compact outer dimensions
- Depending on the federal state, the small footprint also eases the permit question, but only the building authority can settle that bindingly
- No anteroom: changing and cooling down take place outdoors or in the house

Karibu sauna house Helmi
- Choice between untreated wood and modern terra grey: the garden decides the look, not the catalogue
- Heater optionally configurable, from entry-level setup to comfort equipment
- Karibu construction with the backing of an established manufacturer
- Anyone looking for maximum floor area for the money gets more sauna per euro with the classic Karibu houses

Home Deluxe Hygge Deluxe
- Deliberately modern appearance that stands apart from the classic log cabin look
- At around 230 x 220 centimetres, a balanced middle ground between a compact house and an XXL model
- Home Deluxe is established as a supplier in the infrared and home sauna sector
- You should check the heater setup and scope of equipment carefully in the product description before buying
Sauna house or barrel sauna: the honest comparison
The sauna house is the grown-up form of the garden sauna: vertical walls, full headroom on both upper and lower bench, and a floor plan that can be furnished sensibly. Larger models add an anteroom that serves as a wind-protected changing area, towel store and transition zone between 90 degrees and winter air. The barrel sauna counters with a faster heat-up time thanks to its smaller air volume, lower weight and its undeniable eye-catcher factor, but its curve wastes space in the corners. Our rule of thumb: anyone who uses a sauna regularly and comfortably is better off with the house, and anyone who wants a garden eye-catcher with a small foundation is better off with the barrel. Our garden sauna overview compares both designs in detail, and the barrel sauna comparison shows the best barrels.
Foundation and three-phase power: what you need to prepare
A sauna house is not a piece of furniture but a small building project. The first job site is the ground: level, load-bearing and permanently dry. Depending on the soil, a concrete slab, a strip foundation or neatly laid paving slabs on compacted gravel have proven effective, plus a capillary-break build-up against rising damp and some air beneath the foundation timbers. The second job site is the power: the 9 kW heaters common here run on 400 volts, and the underground cable from the house connection to the sauna house and the connection itself must be handled by a qualified electrician. Plan for cable, trench and connection costs from the start. Our sauna heater buying guide explains which heater output suits which cabin size; you will find bucket, ladle, thermometer and sauna light in the accessories section.
Wall thickness: what 38 millimetres mean
For garden houses, 28 millimetres counts as standard, while sauna houses such as the MELO 3 rely on 38 millimetre solid planks, and for good reason: the thicker wall stores more heat, warps less under the extreme swings in temperature and humidity, and keeps the heater from running continuously in winter. Even thicker walls or additional insulation improve the energy balance further, but drive up price and assembly effort. For private year-round use, 38 millimetres is in our view the sensible sweet spot; more important than the last millimetre of wall are a tight roof, a good door and a properly set up heater.
Planning permission: ask first, then build
The uncomfortable truth first: whether your sauna house needs a building permit is decided not by the retailer but by the state building regulations of your federal state together with the local development plan. In many places small outbuildings are exempt from procedure up to a certain number of cubic metres, but a sauna house with a firing appliance or heater is sometimes assessed more strictly than a tool shed, and setback distances to the neighbour almost always apply. Our advice: before ordering, call the building authority with a floor plan and a site sketch, which costs nothing and spares you expensive demolition. We have summarised the typical rules, exemption limits and pitfalls in the guide Garden sauna and permits.
Which sauna house suits whom
The short decision aid from the editorial team: anyone building for the first time and wanting a coherent overall package should take the MELO 3 complete set, where house, heater and stones fit together from the factory. If year-round use with the family is the priority, the Karibu garden sauna with anteroom is the most comfortable solution, and its two loungers and external heater control make the difference in everyday use. Technically minded DIY equippers should go for the MELO 3 without heater and put together their preferred combination. For smaller plots the compact Karibu at just under two by two metres is intended, while design-conscious buyers choose the Helmi in terra grey or the modern Hygge Deluxe from Home Deluxe. If you are still undecided between designs, our Sauna Finder leads you to the right solution in a few questions.
How we assessed
Our editorial rating weighs four criteria: the substance of wall thickness, wood quality and construction, the heater package including control, the equipment from doors to loungers to anteroom, and everyday practicality from assembly, footprint and running costs. The basis is manufacturer and retailer information as well as documented user experiences, not our own assembly on the editorial plot, and that is exactly how we label it. You will not find invented measurements or fantasy prices here, and our editorial team stands behind that. Price classes instead of daily prices: for sauna houses, mid-range means the middle four-figure range, and the premium class goes beyond that. The price in the linked shop is always what counts.
Conclusion
A garden sauna house is the most long-term sauna decision you can make, and that is exactly why the order matters: first clarify the building authority and electricity questions, then plan the foundation, then choose the house. The MELO 3 complete set takes most decisions off beginners' hands, while the porch model rewards anyone who wants to sauna in January too. Calculate honestly: house, electrics, foundation and accessories together make up the real budget. After that, though, you have something in the garden that gets better every winter.
