Frequently asked questions
Does the price include a stove or heater?
No. The hot tub is supplied without a stove or heater. An upgraded 2 kW heater set is available as an optional extra. It works best alongside a primary heater such as a wood-burning stove or a more powerful electric heater.
How is it delivered?
Fully assembled on a pallet by tail-lift truck. Because of its size and weight, please make sure there is suitable access for unloading. It needs to be placed on a solid, level surface.
What should I check when it arrives?
Inspect the hot tub for damage before signing the delivery receipt. If you find any, note it on the delivery document, take photos and report it to us within 7 days.
What warranty is included?
A 2-year factory warranty for private use, or 6 months for commercial use, starting on the date of delivery. It covers defects in materials and workmanship, provided installation and use follow the guidelines. The tub must be installed within two weeks of delivery to remain under warranty.
Can I cancel my order?
You can cancel before production begins for a full refund. Once production has started, cancellations and refunds are not possible because each hot tub is custom made.

Let customers speak for us
This is a great sauna. We specifically liked this format instead of the barrel saunas. Delivery took around 6 weeks. We built it ourselves from flat pack which was relatively easy if you’re mechanically minded. We’ve had our first of many sessions in it and it’s wonderful. Even just sitting in there with no burner is really relaxing. Espeically with your morning coffee. We highly recommend Roman Oasis for their amazing product, service and support along the way.
We couldn't be happier with our Baltresto 2-person oval wood-fired hot tub. From the ordering process through to delivery, everything was smooth and well organised. The quality of the craftsmanship is excellent, and once set up it became an instant focal point in our garden.
The wood-fired heater brings the water up to temperature surprisingly quickly and creates a lovely traditional hot tub experience. It's the perfect size for two people, making it ideal for relaxing after work or enjoying an evening outdoors. The insulated cover helps retain the heat, and the whole tub feels very solid and well made.
We've been impressed with both the product quality and the overall experience, and would happily recommend Baltresto to anyone looking for a high-quality wood-fired hot tub.
This wood-fired barrel sauna is perfection. The barrel shape heats up fast and circulates steam beautifully with no cold spots. The wood stove creates a deep, relaxing heat and amazing crackling ambience that electric models can't match. It looks stunning and smells incredible. Worth every penny! I had a fun building it with my dad and a mate. Definitely needed their help! Roman oasis was so easy to contact via WhatsApp and I asked loads of questions all the time, great service from start to finish. They even checked up on me a month or so later just to check all was okay.
From our first enquiry to its first use we have had no problems, easy to order, customer service is fantastic, delivery was quick and efficient. We have hesitated for a long time as only have a very small garden but so glad we went for it. Would highly recommend to anyone thinking about one. Ours is the oval woodfired 2 person hot tub, with 1 light and standard bubbles which is just perfect. Insulated lid keeps hot tub warm and just needs a quick wee fire to top up the heat. Wooden steps finish off the look. Put our parasol over the hot tub and sat out in the rain tonight!!! So happy with our purchase, thanks to all at Roman Oasis.
From the enquiry stage, the staff provided helpful information via WhatsApp. Although there was a slight delay in production, they kept us updated throughout the process. Delivery was initially unsuccessful due to a courier issue, but the company was accommodating and worked with us to arrange a smooth delivery. There were also some minor defects on arrival, and while these shouldn't have been present, the company responded appropriately and took steps to rectify them.
The Ella Cube Sauna itself is very good and performs as expected. Reaches temps of 70-90 in less than 15 minutes and reaches 100+.
Overall, while there were a few issues along the way that affected the experience, the company was responsive and willing to resolve problems when they arose.
A special thanks to Louis for his help throughout the process and for assisting in getting the issues resolved.
Firstly I have to say how great Louis from Roman Oasis was throughout the whole experience with his knowledge and communication. The Sauna is absolutely amazing and we couldn't be happier with the whole experience.
Thanks again Roman Oasis
Roman Oasis were so helpful. Louis was on hand to help with any questions, delivery instruction and after service. I could not fault their customer service.
The sauna itself is absolutely stunning. We have very high standard and it certainly lives up to those.
Instruction manual was helpful and easy to understand
What a fabulous experience.
Helpful staff, easy to order, kit arrived safely, easy to assemble.
I’ve used this every day and it’s quick to heat up, very comfortable for one person.
I love it couldn’t recommend it more highly.
I received my Baltresto wood fired hot tub well within the time stated and was kept up date with progress throughout the build process. I ordered the flat pack self build tub as access to my garden is limited. The tub and heater were delivered right to my drive way and everything was packed and protected extremely professionally. It was easy remove the stainless steel hex screws from the pallet and protection and move the components parts to my garden. The tub was pretty easy straightforward to assemble with very clear instructions, the last piece was a bit tricky but went in with a little help holding the slats in that need to be moved out to get a really tight fit. The heater and chimney fitted easily and heated the tub up nicely after about 1.5 hours. Well recommended.
I purchased the Baltresto hot tub a few weeks ago. I had to go for the kit form of hot tub, as I have limited space to get anything into my garden. It arrived on time and packed really well. Assembly was very straight forward and easy. I opened for a few extras which took a little thinking about, but we're also straight forward to fit. As expected there were leaks when filling it up for the first time, but once the wood was wet and had expanded, the leaks all closed up. The wood fire heating system was quicker than I expected it to be and works exceptionally well - can't wait for the winter now). I have had plenty on nice times in it in the last few weeks , enjoying the late summer evenings and the crystal clear nights with a glass of wine. Exceptionally pleased with the idea and the outcome, I am sure it's going to be a lot of fun.
first off can I just say the customer service was amazing kept up to date with messages to let me know how everything was going up until the shipping date. packaged and wrapped amazingly. Easy to place with 2 people by hand once unwrapped, takes a little to get the fire attached but easy enough. excellently made and looks the business. very comfy to sit in and the fact its a woodburner makes it all the better. Can't say enough about Roman Oasis and their product absolutely brillaint.
The perfect alternative to other hot tubs! We purchased the Oslo after researching more cost effective options online. It’s great! Gets toasty hot without too much waiting, great bubbles and LED lights. We use it so often and are such a fan. Service from Roman Oasis was amazing and such quick delivery!
Broken part was delivered within days
As I'm getting older, I decided to invest more in my health. After seeing podcasts on cold plunge benefits and from personal research, I had to get the real thing. Addicted. I have had the chillax tub for just over 3 weeks now, and if I don't get in first thing in the morning ,my day feels slugish... Additionally, the team at Roman Oasis made the delivery and setup as simple as possible with great help from Louis over the phone. Couldn't recommend them more, Thanks!
