What we're praised for most often
- Delivery as agreed. The building arrives on the agreed day, sometimes even ahead of schedule, and many take their first sauna the very evening it's delivered.
- Changes to the standard model. The positions of windows and doors, the width of the sauna benches, an extra log course or converting the sauna into a guest house are all possible, and the designer often suggests a better solution.
- Service. Questions are answered quickly, and the sales approach doesn't feel pushy.
- The löyly. The löyly is the most common thing praised in written reviews: about a third mention it. Recurring words are ”oxygen-rich”, ”moist” and ”soft”, and many praise the flow of replacement air from the floor edges.
- Quality and price. Sturdy logs, wide sauna benches and open pricing: prices are on show, and you don't have to guess the total price.
What we get criticised for
- Small shortcomings in the delivery. For example, missing parts, spots dented in transit or slips in the finishing. According to customers, these are usually put right quickly, but in individual cases the repair has taken a long time or the compensation has been small.
- Transport arrangements. The exact delivery day has sometimes only become clear a few days beforehand, and the width of the access route to the plot should have been confirmed earlier.
- Choosing the size. A few customers would now buy a model one size larger.
Based on the feedback, we have, among other things, clarified our guidance on the access route.

Questions about customer experiences
What are people's experiences of Ehta?
251 customers have responded to our customer satisfaction survey, giving an overall rating of 4.7/5 and an NPS of 86. Customers most often praise the löyly, a delivery that went as agreed and the chance to customise a standard model.
Does an Ehta building arrive on the agreed day?
Keeping to the delivery schedule is the second most common praise in the reviews. The exact time of transport is confirmed a few days beforehand, and it's worth confirming the plot's access route already at the ordering stage.
Can an Ehta model be modified?
Yes. Customers have changed, among other things, the positions of windows and doors, the width of the sauna benches and the height of the building, as well as turning the sauna into a guest house.
What if there's something wrong with the delivery?
Missing parts and transport damage are repaired under warranty. According to the reviews, most cases are dealt with quickly.
